Cyera Agrees to Acquire Oasis Security for $1B to Safeguard Proliferating AI Agents
Cyera acquires Oasis Security for approximately $1 billion to strengthen its position in the emerging market of AI agent security, as enterprises increasingly deploy autonomous AI systems that require new identity management and monitoring capabilities.
A Major M&A Move in the AI Security Space
Data security company Cyera has announced it signed a letter of intent to acquire Oasis Security for approximately $1 billion, marking one of the largest deals in the emerging field of AI agent security.
The deal was announced on Tuesday, July 28, 2026, and is expected to be paid mostly in cash with the remainder in Cyera shares.
The Players
Cyera
- Recently raised $600 million at a $12 billion valuation
- Shares investors Accel and Cyberstarts with Oasis Security
- Has been on an acquisition spree, recently purchasing Index Ventures-backed Ryft and Genie Security (which was less than one year old)
- Surpassed $150 million in annual recurring revenue (ARR) as of last month's reporting
- Has raised about $2.3 billion in total funding across multiple rounds
Oasis Security
- Founded in 2022
- Focuses on non-human identities, primarily AI agents
- As the number of AI agents proliferates, companies must deploy cybersecurity software that monitors these agents' behavior and grants them permission to access other software
- Has raised about $195 million from investors including Accel, Craft Ventures, Cyberstarts, and others
Why This Deal Matters
The acquisition highlights a surging market for cybersecurity providers defending enterprises against AI-weaponized threats. As AI agents become more autonomous and capable, the need for robust identity management and security monitoring grows exponentially.
Post-acquisition, Cyera plans to integrate Oasis's technology into a unified identity and data security platform, strengthening its position in the enterprise security market.
The Broader Context
This deal comes at a critical time for AI security: - AI agents are increasingly being deployed across enterprises - Traditional cybersecurity approaches are struggling to keep pace with autonomous AI systems - The number of AI agents proliferating faster than defensive capabilities can scale - Companies need new tools to monitor AI agent behavior and grant appropriate access permissions
Cyera's acquisition spree demonstrates investor confidence in the AI security market, even as the company remains far from profitable despite its strong ARR growth.
Shared Investor Backing
Both Cyera and Oasis share investors Accel and Cyberstarts, suggesting these backers see significant opportunity in the intersection of AI agents and cybersecurity. This shared ownership structure may facilitate the deal's execution and integration.
