Ondrej Vlcek’s New AI Startup Aisle Emerges from Stealth to Change the Rules of Cybersecurity

Cybersecurity has always been complex, but today it poses an even greater challenge for companies. Thanks to AI, attackers now have access to new technologies that allow them to target their victims more effectively, faster, and more cheaply than ever before. Aisle is an AI-native system capable of autonomously identifying, diagnosing, and—once approved by a human—remediating vulnerabilities in complex software applications and IT systems. The first version of the product is entering the market after a year of intensive development and research.

“The rapid development of AI brings us many new useful tools and is transforming entire industries. But in the realm of cybersecurity, this shift has so far benefited attackers more than defenders,” says Ondřej Vlček, founder and CEO of Aisle. “Aisle wants to put the advantage back into the hands of those fighting these attackers. With our team, we’re trying to solve perhaps the most challenging cybersecurity problem of all: how to quickly and accurately detect and fix vulnerabilities in corporate systems. We want to give the people responsible for system security hope that a fully cleared vulnerability backlog doesn’t have to be science fiction.”

Aisle offers a solution that cuts the time required to fix vulnerabilities—from the current weeks or even months—to mere hours or even minutes. All fixes are verified against a continuously updated AI model of the company’s software environment. Aisle operates at such scale that it can reduce the accumulated number of unresolved vulnerabilities from the usual hundreds of thousands or millions down to zero, and it can uncover security flaws invisible to human experts.

Today, the company is emerging from stealth after a year of work by a nearly 40-member team and product testing with design partners, including originally Czech companies Productboard, Ataccama, and Livesport. The research division at Aisle is led by one of the company’s founders, top AI scientist Stanislav Fort. His team was tasked with developing a solution that none of the current major players in cybersecurity possess. “The goal was to build an autonomous end-to-end system that can identify potential threats in real depth and then—under human supervision—automatically eliminate them. Even during the testing phase, Aisle successfully found and fixed vulnerabilities in some of the world’s most critical software projects,” explains Stanislav Fort.

Aisle is the project of three founders. In addition to Stanislav Fort, the founders include former Avast (later Gen) CEO Ondřej Vlček and Jaya Baloo, who previously served as head of security at several global companies. Ondřej Vlček serves as CEO at Aisle, while Jaya Baloo holds the role of COO. The team includes senior members with degrees from universities such as Stanford, Cambridge, MIT, Caltech, and ETH, and with work experience from major tech firms. The technical team also includes members from Israel, which is a global cybersecurity powerhouse.

Renowned angel investors have also supported the company in its early stages. They include Google’s Chief Scientist and legendary engineer Jeff Dean, Hugging Face co-founder Thomas Wolf, Datadog CEO Olivier Pomel, Microsoft Chief Product Officer and former Google VP Aparna Chennapragada, podcaster Dwarkesh Patel, and one of the most influential researchers in modern machine learning and former Director of ML at Apple Ian Goodfellow.

“Aisle is a mission I devote all of my working time to. I consider cybersecurity an extremely important issue. We want to develop a product that helps not only large corporations but also organizations maintaining open-source projects that power our critical infrastructure. Protecting them from increasingly sophisticated cyberattacks will become ever more crucial for functioning democratic societies,” concludes Ondřej Vlček in his Linkedin post.

Existing tools are unable to reliably detect deep vulnerabilities and overwhelm security teams with false positives. Some newer products do add AI features, but still fail to deliver the required accuracy, speed, and scalability—especially when it comes to automatically fixing and validating those fixes in real software environments.

Aisle is an AI-native system capable of autonomously identifying, diagnosing, and remediating vulnerabilities even in very complex applications and IT infrastructures. However, humans still have the final say—full control over the entire system remains in their hands, and they can review and approve individual findings and fixes before they are deployed to production.

The system creates a live model of an organization’s software environment, which is continuously updated and learns from every interaction. Aisle can simulate changes and detect regressions, potential outages, and other issues in advance, before individual pull requests are created. It has deep contextual understanding and can handle code repositories and dependency graphs of any size, making it suitable for deployment even in the complex environments of large enterprises.

Aisle is at the forefront of a new generation of autonomous vulnerability management. Its AI-native system uncovers vulnerabilities that traditional tools cannot detect and autonomously generates and tests fixes, reducing resolution time from weeks or months to hours or minutes—while maintaining human oversight.

Aisle transforms vulnerability management from a costly, thankless bottleneck into a scalable, autonomous process that gives defenders a technological advantage and significantly increases an organization’s resilience to cyberattacks.
