Cohere moves to buy AI cybersecurity startup AISLE

By Leo Marchandon

Oct ‌15 (Reuters) - Canadian ​AI ​lab Cohere said on Thursday it had signed a letter of intent to buy ‌AISLE, a San Francisco-based cybersecurity startup that uses AI to ⁠detect vulnerabilities in software.

The tie-up would add cybersecurity to the ‌business entity Cohere is ‌assembling through its merger with Germany's Aleph Alpha, a combination reported to be worth about $20 billion, and extend ​its European footprint with AISLE's engineering hub in Prague.

Cohere said the acquisition reflected its continued investment ⁠in Europe and would deepen its presence across the region, strengthening ​European AI.

The deal is aimed at boosting the combined group's security and threat detection capabilities for ​enterprise and public sector clients, ‌with private deployment available on the customer's own system.

"Increasingly capable AI systems are transforming ⁠both cybersecurity and the threats organizations face, and defensive capabilities must advance just as quickly," Cohere said.

AISLE was founded ⁠in 2025 by Ondrej Vlcek, former CEO of Czech antivirus maker ​Avast, with co-founders from Google DeepMind and Anthropic.

AISLE said its AI found more than 500 new bugs in widely used ‌software in its first year, including 12 vulnerabilities in OpenSSL, a free program that ‌encrypts internet traffic for banks, governments and messaging ⁠apps, which were fixed ‌after their discovery.

The ​terms of the deal were not disclosed.
