Artificial intelligence (AI) and machine learning (ML) are revolutionizing many areas of technology, and cybersecurity is no exception. There is increasing talk of the impact of these technologies on the evolution of both attack methods and defense strategies. Penetration testing, as a key component of security verification, is also facing AI/ML-driven changes. Understanding the potential opportunities, but also the challenges, of these technologies is key to the future of effective security testing. Nflo closely follows these trends to adapt its services and deliver the highest quality security assessment.

How is AI/ML already being used in cyber security tools?
Artificial intelligence and machine learning are already widely used in various cyber security tools and platforms, supporting analysts and automating certain tasks. One of the main areas is advanced data analysis and anomaly detection. ML algorithms can analyze vast amounts of system logs, network traffic or user behavior, identifying unusual patterns that may indicate an ongoing attack or security breach, often much faster and more effectively than a human.
AI/ML is also used in prevention and response systems. SOAR (Security Orchestration, Automation and Response) platforms use AI to automate responses to detected incidents, such as blocking malicious IP addresses, isolating infected systems or triggering appropriate procedures. EDR (Endpoint Detection and Response) and XDR (Extended Detection and Response) tools use ML to detect advanced malware (malware) and endpoint attacks, often based on behavioral analysis rather than just known signatures.
In the field of Threat Intelligence, AI helps process and correlate information from various sources (hacker forums, vulnerability reports, attack data) to identify new campaigns, trends and techniques used by cybercriminals. This allows for faster understanding of the evolving threat landscape and proactive adjustment of defense strategies.
Next-generation security information and event management (SIEM) systems are increasingly integrating ML algorithms to improve incident detection accuracy, reduce false alarms and prioritize alerts that require analyst attention. AI also supports vulnerability analysis, helping to assess risk and prioritize remediation based on context and potential impact.

What opportunities does AI/ML open up for penetration testing?
The potential of AI and ML in the context of penetration testing is significant, although still largely in the development and exploration stage. One promising opportunity is to accelerate and improve the reconnaissance and vulnerability discovery phase. AI algorithms can potentially analyze large amounts of target data more quickly, identify potential attack vectors and suggest the most promising next courses of action for the pentester. ML-based tools can also more effectively detect known vulnerabilities in more complex environments.
AI/ML may in the future support the automation of more complex tasks that today require manual intervention. One can imagine systems capable of autonomously combining identified vulnerabilities into attack chains (exploit chains) or adaptive testing, where the tool adjusts its techniques on its own in response to the defense mechanisms it encounters. This could significantly increase the efficiency and scope of testing, especially in large and complex environments.
Another area is improving performance analysis and reporting. AI can help automatically correlate and group vulnerabilities found, assess their risk in a business context (once properly “trained” on organization-specific data), and generate more precise and personalized remediation recommendations. This can reduce the time needed to analyze the results and prepare the final report.
AI-based tools can also help simulate more realistic and adaptive attacks by mimicking the behavior of specific criminal groups or adjusting attack vectors in real time. This could raise the level of realism of Red Team exercises and allow a better assessment of an organization’s defense capabilities in the face of dynamic threats.
Will AI replace pentesters? The role of human creativity and intuition.
Despite the growing capabilities of AI and ML, the thesis that human pentesters will be completely replaced by artificial intelligence seems unlikely for the moment. Penetration testing is much more than technical scanning for known vulnerabilities. Human creativity, critical thinking skills, intuition and the ability to understand the business context - qualities that current AI systems do not possess - play a key role.
AI excels at repetitive tasks, analyzing large data sets and identifying patterns, but has difficulty thinking “out-of-the-box,” adapting to completely new situations or making decisions based on incomplete information. Pentesters often have to improvise, combining seemingly unrelated facts and exploiting subtle flaws in logic to get around security measures - it takes human ingenuity.
Understanding the business context is key to assessing the real risks of vulnerabilities. The pentester is able to assess what impact exploiting a given gap would have on the company’s business, allowing it to prioritize actions accordingly. AI, even if it identifies a technical weakness, may not be able to accurately assess its significance without a deep understanding of the organization’s business goals and processes.
Ethical issues and decision-making also remain the domain of humans. Penetration testing requires responsible decisions about the scope of the tests, the techniques used (so as not to disrupt production systems) and the interpretation of the results. Entrusting such decisions to fully autonomous AI systems raises serious questions. Therefore, a more likely scenario is synergy - AI as a powerful tool to support and augment the work of human experts, not replace them.
What new security challenges does AI itself pose (e.g., attacks on ML models)?
In addition to new defense capabilities, the development of artificial intelligence also creates new challenges and attack vectors. One is attacks on the machine learning models themselves (Adversarial AI). Attackers may try to manipulate the input data in such a way as to “fool” the model and make it misclassify (e.g., pass malware as a safe file) or leak the information it was trained on.
Another threat is data poisoning, where an attacker inserts specially crafted data into an ML model’s training set to intentionally disrupt its operation or create a “backdoor.” Model theft (model stealing) is another risk, where an attacker attempts to replicate or steal a valuable, trained AI model, which is often a company’s key intellectual property.
The use of AI by cybercriminals themselves also poses serious challenges. AI can be used to automate and scale attacks, generate more convincing phishing messages (e.g., deepfake audio/video), crack passwords faster, or create malware that can adapt and evade detection. The arms race between defenders and attackers in the field of AI is already underway.
These new threats require the development of new security testing methodologies specifically targeting AI/ML systems. Traditional pentesting approaches may be inadequate for assessing models’ resilience to adversarial or data poisoning attacks. It is becoming necessary to develop AI security (AI Security) expertise and tools.

Which half of the work is automatable today
Automation is good at what is repetitive and decidable: is this host patched, is this port still open, did the last release reintroduce a known weakness. It is weak where the significance of a finding depends on business context — an authorisation flaw only matters once you know who the user is and what they can reach. Treating both halves as one budget line is how organisations end up buying scans and calling them tests.
The repetitive half is worth running continuously with validation by exploitation rather than annually: that is the model behind RidgeBot.
