Aisle was started last year by Ondrej Vlcek, the ex-chief executive of Avast, a Czech antivirus provider.

Cohere to Acquire AISLE for Enhanced Cybersecurity Capabilities Cohere, a Canadian AI firm, announced its intention to acquire AISLE, a cybersecurity startup based in Prague, on October 15, 2026. AISLE specializes in autonomous systems that detect and remediate vulnerabilities in software, having identified over 500 previously unknown vulnerabilities in its first year. The acquisition aims to bolster Cohere's cybersecurity capabilities amid growing concerns about AI's dual-use potential in both defending and attacking systems. AISLE's technology has reportedly outperformed many existing solutions in the open-source ecosystem. Following the acquisition, AISLE's co-founders will assume key leadership roles within Cohere, which plans to invest significantly in Prague to establish it as a global hub for AI cybersecurity. Financial details of the deal have not been disclosed. 6 sources 25
