Canadian AI company Cohere announced on October 15 that it has signed a letter of intent to acquire AISLE, a cybersecurity startup that builds autonomous systems to discover and remediate previously unknown vulnerabilities in critical software. Cohere described the move as a proposed agreement rather than a closed deal, and the financial terms were not disclosed. AISLE said it will share more details as the transaction progresses, and that its focus for customers and partners remains continuity and stronger products.
AISLE, founded in 2024, combines foundation models with specialized security expertise, large-scale code analysis, rigorous validation and automated remediation. Its systems are designed to find flaws in complex production software, verify that the findings are real, and help produce fixes that maintainers can trust. That is a different corner of cybersecurity from the detection and response tools most AI vendors sell: AISLE hunts for the unknown bugs already sitting in widely used code, before attackers find them.
The track record behind the deal is unusually concrete for a young company. In its first year out of stealth, AISLE says it discovered more than 500 previously unknown vulnerabilities that were assigned CVE identifiers, spread across more than 100 codebases. Those findings included all 12 vulnerabilities in OpenSSL's January security release and 18 of the 24 CVEs in curl's latest release. Cohere notes that the zero-day findings are independently reviewed by the relevant software maintainers, a check that separates genuine discoveries from the false positives that plague automated scanning.
AISLE's team will join Cohere, and its three founders take senior roles. Ondrej Vlcek, AISLE's chief executive and a former CEO of Czech antivirus maker Avast, will become Senior Vice President, Cohere Cyber, leading a newly established global cybersecurity business. Jaya Baloo will become Cohere's Chief Information Security Officer, responsible for security across the company. Stanislav Fort, who led AISLE's research as its chief technology officer and chief scientist, will become Vice President, AI Security, working with Cohere co-founder and CTO Ivan Zhang to connect security research with core model development and training. Cohere also plans a substantial long-term investment in Prague, expanding AISLE's existing presence there and establishing the city as its global center for AI cybersecurity.
For Cohere, the acquisition fits the sovereign AI platform it has been assembling, following its acquisitions of Reliant AI and Aleph Alpha. The company argues that as organizations move AI from experimentation into production, security has become one of the factors that decide whether adoption succeeds, especially for enterprises and governments that need deployments in private cloud, on-premises and fully air-gapped environments. Cohere expects AISLE's technology to strengthen threat detection, governance and monitoring for AI agents, and protections for sensitive data and mission-critical systems.
There is also a research bet underneath the deal. Both companies say model capability and the specialized system around a model reinforce each other, and Cohere wants to explore how difficult, verifiable security problems can help evaluate and improve future models. Vulnerability hunting is well suited to that test: a claimed bug either reproduces or it does not, and a patch either works or it does not. If the combination delivers, discovering, validating and fixing vulnerabilities becomes a continuous capability inside a frontier AI company, rather than an occasional audit bought from outside.
