Cohere buys two security startups to add cyber defense and secure code review

Cohere is bringing software security into its enterprise AI business through two acquisitions announced as complete on November 13, 2026. Its announcement adds AISLE’s vulnerability-discovery systems and cubic’s AI code review, pairing cyber defense with secure development for enterprises and governments that want to keep AI—and the data it handles—under their control.

Financial terms were not disclosed. The announcement joins two transaction timelines: AISLE said its acquisition formally closed on November 10, when it began serving customers as Cohere Cyber. Cubic separately confirmed its acquisition on November 13.

Finding vulnerabilities versus reviewing changes

AISLE’s work targets previously unknown weaknesses in complex software already in production. Its approach combines foundation models with specialist security knowledge and large-scale code analysis. The process includes validating a suspected vulnerability and assisting with a fix, rather than stopping at a warning that something might be wrong.

AISLE reported that its platform discovered more than 650 vulnerabilities assigned CVE identifiers in the 14 months before its November 10 announcement, according to Unite.AI.

Cubic addresses the review of code changes and the wider task of understanding a codebase. Cohere says its platform can find bugs and security vulnerabilities and automatically remediate issues. Founder and CEO Paul Sanglé-Ferrière and his team will help integrate enterprise coding capabilities into Cohere’s platform.

The shared requirement: customer-controlled infrastructure

Cohere positions both additions around organizations requiring private-cloud, on-premises or air-gapped deployments—networks isolated from external connections. It specifically describes cubic’s review agents as built for on-premises and air-gapped environments. Cohere calls its approach sovereign AI: organizations retain ownership of their data, infrastructure and operations while using advanced AI.

A security business with a Prague base

AISLE’s three co-founders are taking leadership roles across the new business, corporate security and AI research:

• Ondrej Vlcek will lead Cohere Cyber as senior vice president.
• Jaya Baloo will oversee security across Cohere as chief information security officer.
• Stanislav Fort will become vice president of AI Security, joining core model research and training while leading AI security research.

Cohere also plans a substantial long-term investment in Prague, expanding AISLE’s existing presence. The city is intended to become its global center for AI cybersecurity and autonomous security systems.

For existing cubic customers, the immediate commitment is continuity: the company says its product will remain available and fully supported. Its team will keep developing it inside Cohere, with further improvements planned.
