Cohere Acquires AISLE, and the Team Now Operates as Cohere Cyber

AISLE said on November 10 that Cohere has formally acquired it, that the deal closed that morning, and that the team will serve customers as Cohere Cyber. Ondrej Vlcek is SVP of Cohere Cyber. Co-founder Jaya Baloo is becoming Cohere's CISO. Stanislav Fort, who led the engineers, is VP of AI Security. Neither company has disclosed a price.

The numbers

• The close is November 10, 2026, according to AISLE's post that day. Lupa.cz reported the same close, citing Vlcek's LinkedIn announcement.
• AISLE says the platform has found more than 650 CVEs in the last 14 months. In October, Cohere and AISLE both said more than 500 previously unknown CVEs in the first year out of stealth, across more than 100 codebases, including all 12 vulnerabilities in OpenSSL's January security release and 18 of 24 CVEs in curl's then-latest release. Those October counts are the companies' own, and they said maintainers reviewed the findings.
• AISLE called itself the third AI company with European roots to join Cohere, alongside Aleph Alpha and Reliant AI. Cohere said on May 19 that it was acquiring Reliant AI, a biopharma research company with operations in Montreal and Berlin. On September 16 Cohere signed a definitive combination agreement with Germany's Aleph Alpha that was still subject to regulatory approvals, with leadership appointments effective on closing.
• No purchase price appears in the November 10 AISLE post, the October 15 Cohere post, or The Globe and Mail's account of the October letter of intent. The Globe reported then that terms were not disclosed.

Who takes which job

Cohere's October 15 post described a proposed agreement and named the same three roles in the future tense. AISLE's November 10 post treats them as in effect. Vlcek leads the new cybersecurity business. Baloo, AISLE's co-founder and CISO, is becoming CISO of Cohere. Fort is VP of AI Security, and AISLE said the engineers he leads have already finished a first cyber sprint inside Cohere.

"We founded AISLE to solve a global problem, and by combining with Cohere, we have a chance to have a global reach and serve customers across the world's critical infrastructure and defense organizations."

Lupa also described Baloo as Cohere's CIO as well as CISO. AISLE's own post says CISO. This story uses AISLE's title. AISLE said it is joining a team of more than 1,000 people, and that Prague is becoming Cohere's global center for AI cybersecurity and autonomous security systems. Cohere's October post said the company planned a long-term investment in the city and would make it that center.

Where this sits next to the Series E

The acquisition is a separate event from the financing Ultrathink covered in Cohere's Series E. That round, announced October 29, targets up to CAD $7 billion at a CAD $35.7 billion valuation and was still open when that story ran. Cohere's October 29 release pointed at this year's deals for Aleph Alpha, Reliant AI, and AISLE while the AISLE transaction was still a proposal. The November 10 post is the acquired company's account that the proposal has closed.

Cohere's own blog, as of this writing, still leads with the October 15 proposed agreement. A matching close notice from Cohere was not on that blog. The October post said AISLE was founded in 2024 and builds systems that find, check, and help fix previously unknown vulnerabilities, including in private cloud, on-premises, and air-gapped deployments.

What we are watching

The price is still undisclosed. A Cohere closing post would confirm the account AISLE and Lupa have already published. Aleph Alpha is the loose end in the "third European company" line. AISLE grouped it with Reliant AI as a company that has joined Cohere. Cohere's September 16 post still had that combination waiting on regulators, with the new operating and research titles taking effect only at closing. The 650 CVE figure is AISLE's November count, up from the 500 figure both companies used in October.
