What Is a Firewall and Its Role in AI Security?

Introduction: In today’s enterprise landscape, generative AI tools like ChatGPT and Microsoft 365 Copilot are double-edged swords. On one hand, they supercharge productivity; on the other, they create new avenues for sensitive data to slip out unnoticedsornsecurity.com. Traditional cybersecurity defenses are struggling to keep up. Consider a scenario where an employee at a bank pastes confidential client data into an AI chatbot to get quick analysis. A conventional network firewall might not flag this as a threat – after all, the employee willingly sent the data to an allowed external service. Yet the risk is very real: 75% of organizations have already experienced at least one security incident from employees oversharing sensitive information via AI. This phenomenon, often termed “shadow AI” (akin to shadow IT), means staff are using AI tools outside official oversight, potentially leaking data through the “front door” without any malware or hacker involved. The result? Confidential data can reside on external AI provider servers beyond the company’s control, raising alarm bells for security teams and regulators alike.

The stakes are especially high in regulated industries like banking, insurance, fintech, payments, telecommunications, auditing, legal services, and public institutions. These sectors handle mountains of sensitive data – from personal financial records to health information and legal documents – under strict compliance requirements. A leaked customer account detail or patient record via an AI prompt isn’t just an IT mishap; it could be a compliance nightmare under laws like GDPR in Europe or KVKK in Turkey. Regulators have made it clear that using AI doesn’t exempt companies from data protection obligations. (Italy’s Data Protection Authority even temporarily banned ChatGPT in 2023 over privacy concerns!). With fines reaching up to €20 million or 4% of global turnover for mishandled personal data under GDPR/KVKK. CISOs and compliance officers are rightly anxious about AI usage turning into a costly breach or legal fiasco.

So how do we embrace AI’s benefits without sacrificing security and compliance? In this article, we’ll explore the answer through a familiar concept in cybersecurity: the firewall. We’ll break down what a firewall is in the traditional sense, then examine its evolving role in the age of AI. Most importantly, we’ll introduce the emerging idea of an “AI firewall” – a new layer of defense for monitoring and controlling AI interactions in real-time. By the end, you’ll understand how combining traditional firewalls with AI-aware security measures can help your organization innovate safely. Let’s dive in.

Firewall 101: Definition and Evolution in Network Security

A firewall is a fundamental network security system that monitors and controls incoming and outgoing network traffic based on predetermined rulesakamai.com. In essence, it acts as a barrier or gatekeeper between a trusted internal network and untrusted external networks (like the internet). By examining data packets and deciding whether to allow or block them, a firewall helps prevent unauthorized access and filter out malicious traffic. This real-time traffic filtering is a cornerstone of any robust cybersecurity strategy, ensuring that only legitimate, policy-compliant communications flow in and out of your network.

Over the decades, firewalls have evolved significantly. Early firewalls were simple packet filters, checking packets’ source/destination addresses and ports. Modern next-generation firewalls (NGFWs) take things to the next level. An NGFW is not just a port-and-IP filter – it combines the classic firewall functions with deeper threat detection capabilities like Intrusion Prevention Systems (IPS), deep packet inspection, and even malware analysis. Essentially, NGFWs merge the roles of firewall and intrusion detection system (IDS) into one platform, giving security teams more visibility into application-layer traffic and potential attacks. Many NGFWs and related endpoint security solutions also incorporate AI in cybersecurity, using machine learning to detect anomalies or known threat patterns in network flows. For example, an AI-powered NGFW might automatically recognize and block a traffic pattern that resembles a botnet command-and-control communication or flag unusual data exfiltration behavior.

Despite these advancements, the meaning of a firewall at its core remains the same: enforce your security policy at the boundary. If traditional firewalls are the sentries at your castle gates, they decide which visitors (network connections) to let in or out based on a trusted rulebook. But what happens when the “visitor” is an AI conversation that looks innocuous from the outside? This question brings us to the crux of AI security risks and why even the smartest NGFW may not fully protect us in the new era of GenAI.

The Rise of AI Security Risks in the Enterprise

企業において、AIセキュリティのリスクが急増しています。 ( Pardon the brief language switch—let’s get back to English! ) Today’s enterprises are rapidly adopting generative AI across departments, but this enthusiasm comes with new vulnerabilities. Unlike a virus or hacker intrusion that a firewall or IDS might catch, AI-related data leaks often occur via authorized channels in unforeseen ways.

One major risk is “shadow AI” usage – employees using AI tools without IT’s approval or knowledge. Think of a marketing analyst plugging customer data into a free AI copywriting tool, or an engineer asking ChatGPT to help debug code by providing snippets of proprietary source code. These well-intentioned uses can lead to confidential information leaving the company’s secure perimeter. As noted, employees themselves admit to this oversharing: nearly 48% confessed to uploading sensitive corporate data to public AI tools. Each such incident is essentially an unguarded data export that traditional security tools might never notice.

Why are these AI data leaks so concerning? For one, they violate data security compliance controls. Privacy laws like GDPR, Turkey’s KVKK, HIPAA in healthcare, and various financial regulations all demand strict control over personal and sensitive data. When an employee pastes client personal info into an AI prompt, they could be effectively transferring regulated data to a third party without any contract or assurance of protection. For example, a bank employee using ChatGPT might inadvertently share account details, breaching GDPR or banking secrecy laws; a doctor might feed patient information into an AI tool, violating HIPAA; a lawyer could input confidential case details, risking client confidentiality and privilege. These scenarios are not hypothetical – they have driven some organizations to put blanket bans on external AI tools until they can mitigate the risks.

Secondly, intellectual property (IP) and trade secrets are at stake. AI models like large language models (LLMs) learn from provided input. If employees input proprietary code or designs, there’s a chance that data could surface in another user’s output or be stored on the AI provider’s servers. A well-known case involved Samsung engineers who inadvertently leaked sensitive semiconductor code and internal notes to ChatGPT; fragments of that data were reportedly found in later AI outputs, leading Samsung to ban ChatGPT use internally. No company wants to find its “secret sauce” regurgitated by a public AI service.

Third, there’s the reputational hit. If news breaks that your firm’s confidential information showed up in an AI-generated response or, worse, was exposed publicly due to an AI integration, customers and partners will lose trust fast. Just imagine the headlines: “Financial Giant’s Client Data Found in AI Chatbot Response.” This kind of story not only invites regulators to investigate but also erodes your brand’s credibility.

Finally, AI systems themselves can be manipulated in ways that pose security risks. Cyber attackers are exploring prompt injection and adversarial inputs to make AI models behave in harmful ways. For instance, an attacker could craft an input that tricks an AI assistant into revealing other users’ data or executing unauthorized actions. This is a whole new category of threats – where the “attack” is a cleverly designed prompt. Traditional firewalls or endpoint protections don’t understand AI behavior well enough to catch this. It underscores that cybersecurity and AI now intersect in complex ways: we not only have to use AI to defend against threats, but also defend against threats to and through AI.

In summary, generative AI introduces a host of data security and compliance challenges that legacy defenses weren’t built to handle. Companies face a visibility gap – lack of insight into AI data flows and usage – which makes managing these risks difficult. So, where do we go from here? The answer isn’t to throw out our firewalls and DLP systems, but to augment them with AI-aware controls. Enter the concept of an AI firewall.

Traditional Security Tools vs. GenAI: Where They Fall Short

Before we define the AI firewall, it’s important to understand why our existing tools – the firewalls, DLPs, and monitoring systems we’ve relied on for years – are not enough on their own in the GenAI era. Traditional firewalls and Intrusion Detection Systems (IDS) excel at catching known bad signatures, suspicious IP addresses, unusual port activity, and so on. They operate largely at the network level (layers 3 and 4 of the OSI model, and NGFWs up to layer 7 for known application protocols). Data Loss Prevention (DLP) systems add another layer, scanning for sensitive data patterns (like credit card numbers or keywords) in outgoing emails, file transfers, or USB copies.

However, GenAI usage turns data exfiltration into a semantic, context-driven problem rather than a straightforward rule violation. As one security expert aptly said, “Our old tools govern files and folders, but not how AI models connect the dots across data silos.”sornsecurity.com In other words, an AI can infer and generate sensitive information without directly copying a file or database record. For example, an employee could ask an AI, “Summarize the client list from our Q4 sales report,” and the AI might produce a summary that accidentally includes personal data or confidential figures. No file was “stolen,” but sensitive info still got output and possibly shared. A legacy DLP looking for exact patterns might not flag this if, say, specific keywords or number formats weren’t on a blacklist.

Network firewalls, by design, don’t inspect the content of an AI conversation. They see an HTTPS connection to an AI service (e.g., to openai.com or Anthropic’s API) and, if that destination is allowed by policy, the encrypted traffic flows through. The firewall can’t discern whether the payload of that connection was “User uploaded source code and customer data.” From the firewall’s perspective, it was just another allowed HTTPS session. Even an advanced WAF (Web Application Firewall) that a company might deploy to protect its own web apps won’t help if employees are using external AI services – those AI APIs are outside the organization’s perimeter and control.

Traditional DLP solutions also struggle with GenAI. Many DLPs rely on pattern matching (like regex for SSNs or classification of documents). GenAI prompts and outputs are unstructured plain language. They may contain sensitive info in disguised forms (e.g., an employee might prompt an AI with a paragraph of text that includes some client PII mixed in). Without semantic understanding, legacy DLP might miss that. In fact, traditional DLP wasn’t designed for real-time prompt/response flows. It often works on stored data (scanning file servers) or at egress points like email. GenAI interactions are dynamic, often API-driven, and can occur through encrypted channels that evade classic DLP hookup points.

The consequence is a visibility and control gap. Security leaders report that AI adoption revealed blind spots in their governance and policy enforcement 73% of executives in one survey said that using GenAI exposed shortcomings in how they monitor and control data. Clearly, plugging this gap requires something new.

In summary, while firewalls, IDS, and DLP remain critical pieces of a cybersecurity solution, they need backup when it comes to AI. We need a way to inspect and control AI-specific data flows and behaviors – essentially, a firewall for AI. Let’s unpack what that means.

What Is an “AI Firewall”? A Modern Approach to AI Security

Illustration: Conceptual visualization of real-time AI data flows being monitored and filtered – analogous to how a traditional firewall monitors network traffic.

An AI firewall (sometimes called a “firewall for AI”) is an emerging class of security solution designed specifically to protect AI systems and interactions. It’s not a physical device like a network firewall, but rather a software layer or service that sits between users (or applications) and an AI model, monitoring the inputs (prompts) and outputs (responses) in real time. In essence, it acts as a gatekeeper for AI, much like a network firewall does for network traffic, but at the application and data level of AI workflows.

Think of an AI firewall as having two main jobs:

1. Prevent bad things from reaching the AI (input filtering) – for example, detecting and blocking a prompt that tries to make the AI divulge confidential info or execute a harmful action.

   
   

2. Prevent bad or sensitive things from leaving the AI (output monitoring) – for example, stripping or alerting on any response that contains private data, offensive content, or other policy violations.

Crucially, an AI firewall understands natural language and context, not just network protocols. It uses techniques from NLP (Natural Language Processing) and machine learning to analyze prompts and responses. This way, it can catch subtle issues that a normal firewall would miss. For instance, a traditional firewall cannot detect if an AI’s text output contains a company secret – but an AI firewall can scan that text for sensitive patterns or anomalous content before it ever reaches the end-user.

What kind of threats and policies can an AI firewall handle? According to recent analyses, AI firewalls are being built to address a wide range of AI-specific risk vectors :

Prompt Injection Attacks: These are inputs designed to manipulate the model (like an attacker trying to make the AI ignore its instructions and reveal system secrets). An AI firewall can detect known malicious prompt patterns or abnormal prompt structures and block them.

• Data Leakage and PII Exposure: If a prompt or an AI response includes personally identifiable information (PII) or other confidential data (like client names, addresses, code snippets, etc.), the AI firewall can flag or redact that, enforcing data privacy policies. This is key for complying with regulations like GDPR, HIPAA, CPRA, and others that demand no unauthorized personal data sharing.

  
  

• Toxic or Inappropriate Content: AI models might sometimes produce biased, inappropriate, or harmful content. AI firewalls can filter out or modify such toxic outputs to uphold company ethics and prevent reputational harm.

  
  

• API Abuse and Misuse: In scenarios where your company offers an AI API (say a customer-facing chatbot), an AI firewall helps throttle and inspect usage – preventing misuse like DDoS attacks on the AI endpoint, or detecting bots scraping data via the AI. It enforces rate limits and watches for abnormal usage patterns, similar to how an application firewall would, but tuned to AI usage.

  
  

• Model Security and Integrity: Some AI firewalls also guard against attempts to reverse-engineer or exploit the AI model itself (for example, an attacker probing an LLM to extract its training data or to get it to output restricted info). They serve as a shield around the model, ensuring it only sees and says what it should.

It’s important to note that “AI firewall” is a new concept, and different vendors might implement it in various ways. Some might integrate it into the model-serving platform, others might deploy as a proxy or plugin in front of popular AI services. The common thread, however, is real-time, AI-aware filtering and control. In practice, an AI firewall could be a cloud service, an on-prem appliance for internal AI systems, or even an SDK that you integrate into your applications that use AI. The goal is the same: bring the kind of policy enforcement we expect at the network level into the realm of AI interactions.

How AI Firewalls Complement Your Existing Security Stack

You might be wondering, do we really need a whole new “firewall” for AI? Can’t our existing network security tools handle this if we tweak them a bit? The reality is that AI firewalls are meant to augment, not replace, traditional security. They operate at a higher level of abstraction – understanding content and intent, not just packets and protocols. Here’s how an AI firewall works hand-in-hand with your current defenses:

• Deeper Inspection Beyond the Network Layer: While a next-gen firewall or WAF inspects network traffic (IP addresses, ports, URLs, etc.), an AI firewall dives into the semantic content. For example, your NGFW might allow HTTPS traffic to OpenAI’s API (since that’s an approved service), but the AI firewall will inspect what is being sent over that connection – e.g., is an employee’s prompt including a social security number or other sensitive text? It’s like moving the security checkpoint from just the city gates (network perimeter) to also screening the conversation happening in the town square (the AI’s input/output).

  
  

• Behavioral Analytics for AI Usage: Traditional security monitors user behavior in terms of logins, file access, network anomalies. AI firewalls add behavior analysis for AI – they learn what normal prompt activity looks like in your organization and can spot anomalies. If suddenly an employee who never used AI before is now pasting huge chunks of database extracts into a chatbot at 2 AM, that’s an anomaly worth investigating. This is analogous to User and Entity Behavior Analytics (UEBA) in security, but tailored to AI interactions.

  
  

• Adaptive Policy Enforcement: AI firewalls can enforce context-aware rules. For instance, you could set a policy: “Block any prompt that contains more than 100 customer records or any output that contains credit card numbers.” Traditional DLP might catch credit card numbers, but it won’t know what constitutes a customer record in a prompt. The AI firewall, however, can use AI/NLP to recognize if a user is attempting to dump a customer list into an AI. These policies can also tie into user identity – e.g., only allow Finance department users to use a certain AI tool and only for specific purposes, etc. Integration with Identity and Access Management (IAM) means the AI firewall can apply role-based restrictions on AI usage (just like network firewalls integrate with Active Directory for user-based access rules).

  
  

• Audit and Compliance Logging: One unsung benefit of an AI firewall is the detailed logging of AI interactions. For compliance officers, having a record of “who prompted what and what the AI responded” is gold. If regulators or auditors come knocking to ask how you prevent sensitive data leakage to AI, you can show them the AI firewall logs and policies as evidence of data risk management controls. This helps meet frameworks like the NIST AI Risk Management Framework’s guidance on monitoring and governing AI systems. It also aligns with emerging standards like ISO/IEC 42001:2023, which emphasizes continuous monitoring and risk mitigation across the AI lifecycle.

In short, think of the AI firewall as the missing puzzle piece that makes your “AI and cybersecurity” picture complete. You still need your network firewall to keep hackers out and your traditional DLP for classic channels like email – but now you also have coverage for the new AI frontier. The result is a more holistic threat detection and prevention strategy that spans from the network layer all the way up to the AI application layer.

Real-World Examples: Who Needs an AI Firewall the Most?

Every organization using AI should start considering these controls, but let’s zero in on a few high-risk, regulation-heavy environments to see how an AI firewall could be a game changer:

• Banking and Financial Services: Banks have strict data confidentiality rules and are frequent targets of fraud. Imagine a bank employee using an AI assistant to draft an investment report and inadvertently including some client account details in the prompt. An AI firewall would catch that and either block or redact the sensitive bits, preventing a possible breach of financial privacy laws. Many banks have outright banned external AI tools after scares of traders pasting strategies or code into ChatGPT. With an AI firewall, instead of a blunt ban, banks could allow safe usage – employees get the AI help, while the “AI guard” ensures no customer PII or insider info leaks out. This balanced approach preserves innovation (important in fintech competition) while satisfying regulators that data isn’t flying out uncontrolled.

  
  

• Healthcare Organizations: Doctors and researchers are keen to use AI for insights, but patient data is heavily protected under laws like HIPAA. An AI firewall in a hospital setting could enable clinicians to use a genAI tool to summarize medical notes or suggest treatment options without risking a HIPAA violation. For example, if a doctor tries to input a patient’s name or medical record number into the prompt, the AI firewall can scrub it or warn them. Additionally, it can ensure AI outputs don’t include any other patient’s data. This is critical because if an AI was trained on some hospital data, it might accidentally include real patient info in responses – the firewall would act as a sanitizer. The net effect: healthcare can harness AI for efficiency (e.g., drafting discharge summaries) and still maintain data security management and patient confidentiality.

  
  

• Legal Firms and Audit/Consulting Services: These businesses thrive on client trust and confidentiality. An attorney may want to use an AI tool to polish a contract draft, but putting client contract clauses into an external AI risks breaching attorney-client privilege or NDAs. With an AI firewall, the firm can allow AI usage but automatically block any attempt to input personally identifiable client data or large excerpts of contracts unless the AI tool is approved and secure. Audit and consulting firms similarly deal with sensitive financials and plans – the AI firewall can prevent inadvertent sharing of, say, a client’s financial spreadsheet via an AI prompt. In these industries, even a single accidental leak could tarnish reputations, so the risk management provided by AI-aware controls is invaluable.

  
  

• Public Sector and Defense: Government agencies are exploring AI to improve citizen services and analyze data, but they also handle sensitive citizen data and even classified info. Here, an AI firewall could enforce that no classified keywords or sensitive personal data get sent to external AI systems. It can also ensure that AI tools used internally comply with sovereignty requirements (for example, not sending data to an overseas server). Given that public institutions are accountable to strict standards and public scrutiny, having an AI firewall provides assurance that any AI deployment is compliance-proof and secure by design.

Across all these examples, a common theme emerges: visibility and control. Organizations can’t manage what they can’t see. An AI firewall gives security teams visibility into AI usage (who’s using which AI tool, and what data is involved) and control to enforce policies in real time. This is especially crucial in industries facing both heavy regulations and motivated adversaries. It’s no surprise that early adopters of AI firewall-like solutions are often in banking, healthcare, and other sensitive fields.

Best Practices for Implementing AI Security (Actionable Tips)

Introducing AI into your enterprise requires not just technology, but also process and culture changes. Here are some actionable best practices – a multi-pronged approach – to bolster AI security in your organization:

1. Discover and Monitor “Shadow AI”: First, get a handle on what AI tools your employees may already be using. Conduct surveys, check logs for calls to AI APIs, and use discovery tools if available. You can’t protect what you don’t know exists. Simply awareness of widespread AI usage can build the case for management to invest in oversight tools. Many companies are surprised to find dozens of unsanctioned AI apps in use, from coding assistants to marketing content generators.

   
   

2. Establish Clear AI Usage Policies: Develop guidelines that specify what data can or cannot be shared with AI systems. For example, policy may state “No customer personal data or confidential source code should be input into external AI tools.” Also clarify which AI tools are approved for use (perhaps certain vetted, enterprise-friendly ones) and which are off-limits. Communicate these policies through training and internal memos so employees understand the risks (share those Samsung and Italy stories!). When people realize AI prompts could inadvertently leak data, they are more likely to think twice before copy-pasting sensitive info.

   
   

3. Implement Technical Controls (AI Firewalls/DLP for AI): This is where tools like an AI firewall come into play. Evaluate solutions that can provide real-time GenAI monitoring and data leak prevention. The ideal tool should intercept prompts and responses on the fly, whether in the browser, through an API, or integrated in chat platforms. For instance, Sorn Security’s approach is a modern example – it offers real-time detection and blocking of sensitive data in AI prompts across popular tools like ChatGPT, Microsoft Copilot, Claude, etc., acting as an AI usage firewall. Such a tool can instantly enforce your AI policies (from step 2) by technically preventing violations, rather than relying solely on user diligence.

   
   

4. Integrate AI Risk Management into Governance Frameworks: Treat AI risks as part of your enterprise risk management. Align your controls with frameworks like the NIST AI Risk Management Framework (AI-RMF) and ISO 42001. For example, NIST’s AI-RMF suggests continuous monitoring and incident response plans for AI systems – ensure your AI firewall feeds into your SOC (Security Operations Center) workflows and you have playbooks if a policy violation or attack is detected. If your industry has specific guidelines (e.g., the EU AI Act for certain AI uses), factor those in as well. Regularly audit AI interactions and maintain logs; this not only helps in compliance but also in improving the system (e.g., tuning the AI firewall to reduce false positives over time).

   
   

5. Train and Empower Employees: People are a crucial line of defense. Provide training sessions on the do’s and don’ts of AI use. Encourage employees to leverage AI for productivity safely – that means understanding what’s sensitive and why it shouldn’t be shared. Also, foster a culture where if someone discovers a new useful AI tool, they bring it to IT/security for vetting rather than using it under the radar. Consider an internal ambassador program where tech-savvy staff in each department act as points of contact for AI questions and escalate any concerns.

   
   

6. Plan for the Future (Stay Updated): The AI landscape and related regulations are evolving quickly. Assign someone (or a team) to stay abreast of developments – be it new AI capabilities (which might introduce new risks), emerging security tools, or legal changes. For example, keep an eye on the EU AI Act progress, new guidelines from authorities like the Information Commissioner’s Office, or updates to standards. Adapt your policies and tools accordingly. An AI firewall solution that updates its threat intelligence (for new prompt injection techniques or data exposure patterns) will be valuable here.

By implementing the above, you create a layered defense: policies + training prevent many issues at the source; an AI firewall and other controls catch incidents in real time; and oversight/governance ensures continuous improvement and compliance. This layered approach echoes the defense-in-depth strategy long preached in cybersecurity – now extended to the AI domain.

Conclusion: Embracing AI Innovation – Securely and Responsibly

Firewalls have long been guardians of the enterprise network, enforcing the motto “trust but verify” at our digital borders. In the age of AI, we need to apply the same principle to the content and conversations happening with generative AI systems. AI security is now a board-level concern: executives know AI can boost competitiveness, but they are equally wary of becoming the next headline due to an AI-induced data breach. The solution is not to retreat from AI, but to advance our security controls.

By understanding the meaning of a firewall in both traditional and modern contexts, we recognize that while the old firewalls protect our network perimeters, new “AI firewalls” are required to protect our data and compliance perimeters in the era of cloud AI services. These tools give us real-time visibility and control over AI usage – illuminating the shadow AI lurking in organizations and erecting safeguards where needed. They operate in tandem with existing cybersecurity solutions (network firewalls, IDS/IPS, DLP) to fill the critical gaps unique to AI. When done right, this means enterprises can confidently deploy AI to employees and integrate AI into products, without opening the floodgates to sensitive data leakage or regulatory violations.

In practice, implementing an AI firewall and strong AI governance brings immediate benefits: CISOs get a dashboard of every AI interaction; compliance officers get peace of mind that GDPR, KVKK, or HIPAA rules aren’t inadvertently broken; and IT leaders can allow innovative AI tools knowing there’s a safety net in place. It’s about enabling safe innovation. As Gartner might put it in their thought leadership style – the enterprises that thrive will be those that embrace AI boldly, but manage AI risk intelligently.

Remember, security is a continuous journey. Generative AI is a fast-moving field, and threats will evolve. But with frameworks like NIST AI-RMF guiding risk management, and solutions like AI firewalls providing technical guardrails, you can stay ahead of the curve. Encourage your team to be vigilant and report AI-related anomalies, keep refining your policies as you learn, and leverage the expertise of security partners.

Finally, if you’re looking to take the next step in concretely protecting your organization’s AI usage, consider exploring solutions like Sorn Security’s real-time GenAI data leak detection and compliance platform. Sorn Security’s platform essentially functions as an AI firewall – monitoring every AI prompt, blocking unauthorized data sharing, and logging it all for audit. It’s an example of how modern technology can address this very modern problem in a practical way. By deploying such measures, you can transform AI from a risky wildcard into a well-governed ally.

In conclusion, firewalls and AI can coexist in harmony: the key is updating our security mindsets and toolkits to guard the new channels through which data flows. With the right approach, your enterprise can reap the rewards of generative AI while staying secure, compliant, and in control. It’s time to unlock AI’s potential – safely and responsibly.

Implementing these strategies will not only protect your data but also build trust with customers and regulators as you harness AI.
