• Outsourcing pen testing often delivers better ROI, providing access to specialized expertise, unbiased insights, and scalable testing capabilities.

Penetration testing, or “pen testing,” is a simulated cyberattack that helps identify and mitigate security risks before malicious actors can exploit them. In recent years, pen testing has changed significantly due to the rise of AI. Although AI empowers penetration testers to work faster and smarter, it also arms attackers with powerful, evolving tools that make intrusions far more efficient and harder to detect.

This guide explores the impact of penetration testing in AI. We’ll cover what penetration testing is, how AI is reshaping it, the benefits and risks of AI, and how organizations can integrate penetration testing into compliance frameworks like NIST AI RMF and ISO/IEC 42001. You’ll also learn about the CTEM framework and how third-party AI penetration testers like Trava Security can help you.

What Is Penetration Testing?

A penetration test is a service provided by third-party security experts that approaches your systems from a hacker’s perspective. It can uncover vulnerabilities that in-house security teams may miss.

What Is the Primary Goal of Penetration Testing?

The benefits of penetration testing go beyond checking a box on your compliance checklist.

Finding and patching exploitable vulnerabilities

The main goal of penetration testing is to uncover and fix known and unknown vulnerabilities in an organization’s web applications, endpoint security, and networks before hackers find and exploit them. 

Imagine a company shifting to a hybrid work model. Employees now have access to private databases from home. While convenient, these new access points expand the company’s attack surface. Fortunately, the company’s cybersecurity company can run penetration tests to simulate how hackers might exploit weak passwords, misconfigured VPNs, or insufficient multifactor authentication (MFA) to gain unauthorized access. If the tests reveal vulnerabilities in these areas, security teams can immediately strengthen authentication protocols, patch misconfigurations, and tighten endpoint security.

Determining the efficacy of security measures

Cybersecurity teams can also use penetration testing after implementing security upgrades to assess the effectiveness of those changes. For example, suppose your team recently rolled out a new endpoint detection and response (EDR) solution to protect against unauthorized access and malware. A penetration test could simulate an attacker trying to bypass the new system in various ways, such as deploying fileless malware and attempting to escalate privileges on employee devices.

If the test shows that attackers can still evade detection under certain conditions, your team can determine where and how EDR configuration needs to be strengthened. 

Supporting regulatory compliance

To avoid lawsuits, fines, and losing client trust, you must comply with relevant security regulations such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). Pen tests can help you prove compliance with these regulations by making sure your controls work as intended.

What Is Penetration Testing as a Service (PTaaS)?

More organizations are shifting to Penetration Testing as a Service (PTaaS), which allows companies to conduct security assessments more efficiently and frequently than traditional methods. 

Unlike traditional pen testing, which is usually a one-time event conducted annually or after big changes, penetration testing as a service offers ongoing coverage that keeps pace with evolving threats, offering on-demand access to testing teams, continuous assessments, and dashboards that integrate results into security workflows.

How Often Should You Perform Penetration Testing?

Penetration testing isn’t a one-time procedure. Nor is it just a box you check annually. The best pen testing frequency depends on your company’s size, risk profile, and industry. Other factors to consider include:

• Change frequency: Consider testing more frequently if your applications or infrastructure undergo major changes.
• Industry requirements: Highly regulated sectors, such as healthcare, finance, and government, typically require more frequent testing.
• Risk tolerance: Companies that face high risks (i.e., those that process sensitive health data) should invest in more assessments for protection.
• System complexity: The more endpoints, applications, networks, and integrations your IT network has, the larger your potential attack surface. Accordingly, your pen testing frequency should be higher when your IT network is larger.
• Company resources and budget: Smaller firms that handle less sensitive data and fewer systems may not need to undergo pen testing as frequently. However, they still benefit from penetration testing to catch vulnerabilities early and build trust with customers and investors. For leaner teams, partnering with budget-friendly third-party pen testing vendors can provide the right balance of security coverage and cost efficiency.
• Mergers, acquisitions, or digital transformation projects: Anytime your organization integrates new systems, migrates data, or connects with an acquired company’s infrastructure, your attack surface significantly expands. These transitions often introduce hidden vulnerabilities — think misconfigured permissions, unpatched legacy systems, or insecure third-party integrations — that attackers can exploit.

Depending on your industry, different compliance standards outline how often you should conduct testing to stay compliant and avoid penalties. Here are suggested pen testing frequencies for various frameworks and compliance requirements:

Keep in mind that every organization’s needs are different. An intro call with the right penetration testing company can help determine the best pen testing frequency for you.

How Penetration Testing Supports Security and Compliance

Penetration testing isn’t just about protecting assets — it’s a necessity for compliance and governance. It’s also part of a larger security framework: continuous threat exposure management (CTEM).

Continuous Threat Exposure Management (CTEM)

CTEM is a cybersecurity strategy that highlights continuous monitoring. It requires organizations to continually test their environments for weaknesses so they can fix them before threat actors exploit them. Pen testing fits neatly into this framework by validating whether defenses work under simulated pressure.

To implement CTEM, you need to follow these steps:

• Scoping: Determine which assets in your digital infrastructure should be monitored — for example, the systems, processes, and people linked to your most valuable business data.
• Discovery: Identify potential vulnerabilities and points of exposure across your infrastructure.
• Prioritization: Prioritize threats based on their potential impact. For example, your CTEM program may allocate more resources to secure a customer database containing sensitive personal information than to a low-risk internal application.
• Validation: Verify whether the identified threats are potentially exploitable.
• Mobilization: Take steps to minimize and remove risks once they are found.

How Does AI Impact Penetration Testing?

AI is reshaping penetration testing by automating routine tasks and helping testers work more effectively. Its applications span the full testing lifecycle, from streamlining basic workflows to modeling emerging attack trends. 

One of the clearest ways to understand this shift is through the rise of AI-powered penetration testing.

What Is AI-Powered Penetration Testing?

AI-powered penetration testing is the use of AI-based tools and techniques to augment traditional pen testing practices.  Instead of relying solely on manual efforts, AI-driven tools automate repetitive tasks, accelerate vulnerability research, and even help forecast emerging attack patterns. This makes penetration testing steps faster, more comprehensive, and better suited to keeping pace with today’s rapidly evolving threat landscape.

Many organizations access AI-powered penetration testing through Penetration Testing as a Service (PTaaS), which combines automation, AI-driven analysis, and expert human testers to deliver continuous, on-demand coverage. This mixed approach ensures that vulnerabilities are identified quickly and validated accurately.

AI-powered penetration testing provides several clear benefits for penetration testers:

• Automate routine AI-powered penetration testing steps and other workflow components, such as reconnaissance, log analysis, and anomaly detection. This gives testers more time and energy to focus on higher-value activities like exploitation and remediation planning.
• Accelerate vulnerability discovery through large language models (LLMs), which can surface relevant documentation, suggest methodologies, and even generate draft proof-of-concept exploits. LLMs can help testers find weaknesses faster during short engagement windows.
• Protect your organization from future exploits by modeling new attack trends and helping testers simulate new threats before they become mainstream. In doing so, teams can boost defenses in advance — for instance, simulating ransomware campaigns that leverage AI-generated phishing lures before attackers deploy them at scale.
• Speed up research into new or unfamiliar technologies that third-party testers may not be familiar with, such as cloud services, containerization (i.e., Docker and Kubernetes), AI/ML environments, and Internet of Things (IoT) devices. This leads to faster ramp-up time and ensures that tests are comprehensive even in environments that would normally require deep specialized knowledge.
• Build skills by using AI-enhanced labs and AI forecast models to learn and simulate new attack trends and techniques. This hands-on training helps them assess whether your systems are equipped to handle the latest threats and adapt defenses proactively.

AI-Powered Penetration Testing’s Risks and Limitations

While AI for penetration testing is fast, its outputs can’t be treated as final answers. Pen testing requires accuracy and context that only human expertise provides. Without oversight, organizations risk running tools they don’t fully understand, missing vulnerabilities or creating a false sense of security.

Some of the risks of relying too heavily on AI pen testing include:

• Skill degradation: Over-reliance on AI-powered penetration testing tools can erode hands-on skills and critical thinking, especially among junior testers. For example, if testers always rely on AI to generate exploit scripts, they may lose the ability to write or customize them manually when the need arises.
• Data privacy risks: Data passed through AI tools may be used for model training, potentially leading to data leaks and compliance issues. For instance, uploading firewall rules or internal IP ranges to a public AI tool could make that information retrievable by others using the same platform.
• Contextual blind spots: AI often lacks a nuanced understanding of system architecture, business logic, and user behavior, leading to missed vulnerabilities. For instance, an AI tool might flag a misconfigured form field but overlook the fact that the workflow allows privilege escalation through a multistep process that only a human tester would notice. This is why strong AI governance frameworks — which define how teams select, monitor, and audit AI tools — are critical for security teams adopting AI-enhanced tools. This podcast explores the core pillars of AI governance and why human oversight must remain central to your penetration testing strategy.

The rise of generative AI in penetration testing has also lowered the barrier for launching attacks, making it easier for threat actors to:

• Automate attacks: Attackers can use AI to create phishing lures, malicious scripts, and even deepfake content at scale.
• Equalize skills: Thanks to AI, even amateur hackers, or “script kiddies,” with limited technical knowledge can now generate complex attacks using AI tools. This means attacks are more likely to happen.
• Attack scalability: Experienced threat actors can use AI to automate reconnaissance, scale payload delivery, and diversify their attacks faster than ever.

AI as a New Attack Surface

An attack surface is the sum of all possible points where an unauthorized user could try to access a system or its data. Traditionally, this includes exposed servers, unpatched applications, and unsecured endpoints. With the rise of AI, the attack surface has expanded in new directions, with even AI systems themselves becoming new sources of vulnerabilities. Techniques such as model poisoning, prompt injection, and data leakage can create exploitable weaknesses that traditional penetration tests may not detect. 

As such, any AI-generated output must go through strict human review and AI security risk consulting to ensure safety. Teams that blindly trust AI-generated results may:

• Miss vulnerabilities due to unreviewed scripts or misinterpretations.
• Rely too heavily on AI-generated findings without cross-verifying.
• Overlook new AI-specific attack techniques, such as jailbreaks or injections.
• Assume AI tools are up to date when they may not be.

Keep in mind that attackers have all the time in the world, but pen testers are working against the clock. AI can speed things up, but only when combined with human judgment, contextual awareness, and double-checking. Otherwise, teams risk creating a false sense of security that leaves critical vulnerabilities exposed.

How Can Penetration Testing Help Companies Prove Compliance With AI Security Frameworks?

As AI systems become more powerful and deeply embedded in business operations, governments, investors, and regulators are putting increasing pressure on organizations to present clear evidence that these technologies are secure and trustworthy. 

That’s where AI security frameworks like the NIST AI Risk Management Framework (RMF) and ISO/IEC 42001 come in. These frameworks offer structured guidance for identifying, measuring, and mitigating the unique risks associated with AI systems. They emphasize the importance of risk assessment, accountability, and continuous improvement — all of which are supported by penetration testing. A well-scoped and well-documented pen test provides concrete, auditable proof that your organization is proactively identifying real-world vulnerabilities, validating mitigation strategies, and aligning with emerging AI security standards.

Here’s how penetration testing can help demonstrate compliance with both the RMF and ISO/IEC 42001.

NIST AI Risk Management Framework (RMF)

Developed by the National Institute of Standards and Technology, the NIST AI RMF helps organizations design, develop, or use AI systems to manage the risks associated with AI and promote the responsible and trustworthy use and development of AI systems. It’s intended to be voluntary, non-sector-specific, rights-preserving, and use-case agnostic, giving organizations in all sectors and of all sizes the flexibility to implement the framework approaches.

Here’s how penetration testing supports NIST AI RMF functions:

ISO/IEC 42001

ISO/IEC 42001 is the world’s first standard for AI management systems. It establishes requirements for organizations to establish an AI management system — a structured set of policies, objectives, and processes that ensure AI is developed and deployed responsibly. The standard is designed to help companies build trust, demonstrate accountability, and comply with emerging AI regulations.

ISO/IEC 42001 is organized around several areas:

• Leadership and governance: Ensuring that top management sets clear roles, responsibilities, and accountability for AI.
• Risk assessment and planning: Requiring organizations to identify AI-related risks, opportunities, and impacts.
• Operational controls: Implementing processes for data quality, transparency, explainability, and bias mitigation.
• Performance evaluation and improvement: Mandating monitoring, audits, and continual improvement of AI systems.

Penetration testing plays a direct role in supporting these areas. Besides meeting the standard’s requirement to document and manage risks, it also provides real-world validation that controls work under pressure.

For example, testers may probe whether an AI-powered chatbot is vulnerable to malicious prompt injections or whether an ML system can be manipulated through adversarial data inputs. Showcasing resilience against these attacks shows stakeholders and auditors that the company isn’t just complying with ISO 42001 — it’s also proactively testing, monitoring, and improving its AI systems in line with the standard’s intent.

Why You Should Outsource Penetration Testing

While some companies build in-house security teams, outsourcing penetration testing often delivers stronger results at a lower cost. Third-party providers bring specialized expertise, impartial insight, and advanced tooling that in-house staff rarely have the bandwidth to develop. Many organizations now explore models like PTaaS and Continuous Threat Exposure Management (CTEM as a Service) as part of their outsourcing strategy, though the core benefits can be achieved by outsourcing penetration testing on its own.

Key benefits of outsourcing penetration testing include:

• Specialized expertise: External testers work across industries and environments, giving them up-to-date knowledge of the latest attack methods, exploits, and tools. Internal teams, by contrast, are usually focused on day-to-day operations and may not have the time to stay ahead of emerging threats.
• Unbiased perspective: Outside providers can spot blind spots and assumptions that internal teams might overlook. This impartial view helps uncover vulnerabilities that would otherwise slip through.
• Scalability and cost efficiency: Hiring and maintaining a dedicated in-house pen testing team is expensive. Outsourcing allows you to scale testing to your budget, compliance requirements, and evolving risk profile without the overhead of salaries, tools, and ongoing training.
• Continuous coverage: Many third-party providers now offer ongoing assessments and real-time reporting, moving beyond once-a-year testing. This ensures vulnerabilities are caught as your systems and attack surface change.
• Audit and stakeholder confidence: Independent test results carry more weight with auditors, investors, and regulators. They show that your company is taking proactive, external steps to validate its defenses.

How Do You Maximize Return on Investment (ROI) on Your Penetration Testing Budget?

Finding and partnering with a third-party vendor is only the first step. Organizations still need to be strategic about how they invest in pen testing. Here are some best practices for getting the most out of your pen testing budget:

• Determine testing frequency according to business risk level: Highly regulated or high-risk sectors, such as healthcare, finance, and government, may require quarterly testing. On the other hand, smaller organizations might find annual PTaaS coverage sufficient.
• Scope tests properly: Make sure that you accurately determine the scope. If it is too narrow, you may miss critical vulnerabilities. But if the scope is too broad, resources can be wasted. The right vendor can help you pick the best scope based on your environment and compliance obligations.
• Treat results as ongoing input, not a one-time report: Use penetration test findings to remediate your IT systems continually. When paired with CTEM, every round of testing builds on the last. The result is a continuous cycle of fixes and improvements that strengthen your defenses with every pass.
