YesWeHack Deploys AI Agents to Hunt Bugs, Redefining the Pentest

PARIS, France – June 25, 2026 – In a cybersecurity landscape where attackers are increasingly leveraging AI to accelerate their campaigns, the defense is fighting fire with fire. YesWeHack, a leading European offensive security platform, today announced the launch of Agentic Pentest, an on-demand solution that deploys autonomous AI agents to probe corporate defenses. The move signals a significant strategic shift in how enterprises can approach vulnerability management, promising to deliver actionable security findings on the same day a test is initiated.

This isn't just another automated scanner. The solution is already being rolled out at French industrial giants Dassault Systèmes and Sanofi, along with other CAC 40 companies, lending immediate enterprise-grade credibility to the technology. By moving from simple automation to AI-driven autonomy, the Paris-based firm is betting that it can provide the speed, scale, and efficiency that modern Security Operations (SecOps) teams desperately need to keep pace with adversaries.

From Automation to Autonomy: The Agentic Shift

For years, penetration testing—or pentesting—has been a largely manual, time-intensive, and costly endeavor, relying on skilled human ethical hackers to simulate attacks. While effective, this traditional approach often struggles to match the relentless pace of software development and the sheer scale of modern digital attack surfaces. YesWeHack's Agentic Pentest aims to shatter this paradigm by using autonomous AI agents to conduct black box, grey box, and white box testing across web applications, APIs, and mobile apps.

These agents are built on advanced frontier AI models, capable of more than just pattern recognition. They can plan multi-step actions, utilize tools, and adapt their strategies with minimal human intervention to uncover complex attack paths. This capability is crucial for identifying not just isolated weaknesses, but how they can be chained together to create a significant breach.

“Agentic Pentest is faster and simpler to set up and run than traditional human-led pentesting, while offering broader coverage, greater scalability and lower costs,” commented Guillaume Vassault-Houlière, CEO and co-founder of YesWeHack. “This enables SecOps teams to identify and remediate vulnerabilities more quickly – an imperative as attackers become increasingly empowered by AI and exploitation windows continue to shrink.”

The business implications are clear. By providing validated findings as the test progresses, the solution drastically shortens the feedback loop between discovery and remediation. This allows security teams to move from a reactive posture to a proactive one, continuously hardening their defenses against high-impact vulnerabilities like those on the OWASP Top 10 list.

The Human-in-the-Loop Imperative

Despite the power of its new AI, the company is adamant that this is about augmentation, not replacement. The rise of agentic AI has stoked fears of job displacement across many industries, and cybersecurity is no exception. However, YesWeHack's strategy is built on a “human-in-the-loop” philosophy, ensuring that human expertise remains the ultimate arbiter of risk.

The AI agents operate within strict guardrails developed by the firm to protect the confidentiality and integrity of customer systems. Furthermore, customers can opt for a 24/7 in-house triage team to validate, reproduce, and enrich the AI's findings. This service guarantees zero false positives, a persistent challenge for purely automated tools that often flood security teams with unactionable alerts. By filtering out the noise, human experts can focus their attention on vulnerabilities that pose a genuine, provable threat.

This approach reframes the role of the human pentester. Instead of spending hours on repetitive reconnaissance and scanning, they are elevated to a more strategic function: analyzing the complex, nuanced findings flagged by the AI, understanding business context, and simulating the creative, out-of-the-box thinking that remains a uniquely human skill. This partnership allows organizations to leverage the machine's speed and scale alongside the human's critical thinking and ingenuity.

Critically, YesWeHack has committed that data generated by its massive bug bounty programs—which leverage a community of over 150,000 ethical hackers—will not be used to train the AI models for Agentic Pentest. This decision demonstrates a clear respect for its human hacker community and addresses potential ethical concerns around data usage, reinforcing trust in its hybrid model.

A Unified Front Against Evolving Threats

Agentic Pentest does not operate in a vacuum. Its true value for the enterprise is its integration into YesWeHack's broader exposure management platform. For a Chief Information Security Officer (CISO), managing risk is about having a single, coherent view of the organization's security posture. Disparate tools create data silos and operational friction.

YesWeHack addresses this by unifying the findings from Agentic Pentest alongside those from its other core services: human-led Bug Bounty programs, Continuous Pentesting, and Vulnerability Disclosure Policies. This integrated platform provides centralized remediation workflows, analytics, and reporting, simplifying compliance and giving leadership a clear, consolidated view of cyber risk. This focus on operational efficiency is a direct appeal to the bottom line, turning security from a cost center into a streamlined business enabler.

This strategic vision is further bolstered by the 2025 acquisition of cybersecurity audit firm Sekost, whose customers will now gain access to the new AI-driven capabilities. The acquisition expands YesWeHack's market footprint and provides a ready-made channel for wider adoption of its integrated security model.

As the solution is already live on external attack surfaces, the company has its sights set on the future, with a roadmap that includes developing support for internal testing scopes. This planned expansion shows a commitment to providing comprehensive, end-to-end security validation, solidifying the partnership between human experts and their new AI counterparts in the ongoing battle to secure the enterprise.
