Onyx Security: sovereignty score and 8 European alternatives

Onyx Security sells what it calls a secure AI control plane for enterprise AI agents. The platform discovers sanctioned and shadow AI across SaaS, cloud, endpoints and code, and gives visibility into prompts, responses and agent actions. It enforces security and governance policies, which teams can define in natural language, and a supervisory Guardian Agent monitors the platform and can block an action, require human approval or redirect the agent. Listed integrations include Anthropic, OpenAI, Amazon Bedrock Agents, Microsoft Copilot Studio and Google. It is delivered as a vendor-operated platform.

Onyx Security came out of stealth in March 2026 and lists offices in Tel Aviv, Israel, and New York. Israel is outside the EU and EEA. The company operates a Trust Center that lists compliance certifications and subprocessors on request. The sources consulted do not state where the platform is hosted and describe no self-hosted option or open-source edition, so European organisations should ask where their data is processed.

Why digital sovereignty matters with Onyx Security

Onyx Security is headquartered in IL, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Onyx Security hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Onyx Security is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Onyx Security together with your other vendors and gives a total score, a heatmap and the main risk drivers.
