Cohere signs letter of intent to acquire cybersecurity firm AISLE

Cohere confirmed on October 15, 2026, that it has signed a letter of intent to acquire AISLE, a cybersecurity startup that builds autonomous AI systems to find, verify, and help fix previously unknown vulnerabilities in critical software. The announcement, posted on both companies’ sites, marks a significant move by the Canadian AI lab into the vulnerability-hunting sector. The financial terms of the proposed transaction were not disclosed.

Deal Structure and Leadership Changes

The agreement is currently a non-binding letter of intent, a step that precedes a leading agreement. According to BetaKit, AISLE’s approximately 50 full-time employees will join Cohere. AISLE CEO Ondrej Vlcek, the former CEO of antivirus company Avast, will join Cohere as senior vice-president of a new cybersecurity unit called Cohere Cyber. Co-founder Jaya Baloo will become Cohere’s global chief information security officer, and co-founder and CTO Stanislav Fort will serve as vice-president of AI security.

While Reuters describes AISLE as a San Francisco-based startup with an engineering hub in Prague, BetaKit reports that AISLE’s Prague headquarters, which hosts an engineering hub, will become Cohere’s Prague office. The joint announcement states that the Prague office is intended to become Cohere’s Prague office if the transaction closes.

AISLE’s Technology and Track Record

AISLE was founded in 2025 by Vlcek, Baloo, and Fort, who have backgrounds at Google DeepMind and Anthropic. The company’s technology uses AI to identify, validate, and help remediate previously unknown vulnerabilities in complex production software. According to the announcement, AISLE identified more than 500 previously unknown vulnerabilities assigned Common Vulnerabilities and Exposures (CVE) identifiers across more than 100 codebases in its first year. These included all 12 vulnerabilities in OpenSSL’s January security release and 18 of the 24 CVEs in curl’s latest release. The vulnerabilities were independently reviewed by the relevant software maintainers.

Cohere co-founder Ivan Zhang wrote in an X post that there are "meaningful gaps in solutions available for [cyber] defenders," and that many organizations face a tradeoff between securing systems and exposing intellectual property to providers. Zhang stated that with AISLE, Cohere will "continue to empower defenders with a truly sovereign platform that they can fully trust to secure their most critical systems."

Strategic Context and European Expansion

The acquisition aligns with Cohere’s strategy to expand its sovereign AI capabilities in Europe, where governments and enterprises seek AI systems that meet strict requirements for security, privacy, and data sovereignty. Cohere has previously acquired Reliant AI and announced a partnership with Germany’s Aleph Alpha. The proposed deal would further strengthen Cohere’s presence in the region, adding AISLE’s engineering hub to its European footprint.

Cohere stated that "Increasingly capable AI systems are transforming both cybersecurity and the threats organizations face, and defensive capabilities must advance just as quickly." The company aims to combine AISLE’s autonomous security research with its frontier-model development to improve cybersecurity systems and create opportunities to use complex, verifiable security tasks to assess and enhance future AI models.

Why it matters

This move signals Cohere’s intent to differentiate itself from US-based AI labs by focusing on sovereign, on-premises deployment for government and regulated industries. By acquiring a specialized vulnerability-discovery firm, Cohere is integrating security directly into its AI infrastructure, addressing a critical pain point for enterprises that cannot send sensitive code to external clouds. The deal also highlights the growing convergence of AI development and cybersecurity, as labs race to apply frontier models to both defensive and offensive security challenges.
