Pillar Security: sovereignty score and 8 European alternatives

Pillar Security offers a platform for discovering, testing, securing and governing AI agents. Its modules cover AI discovery and posture management, including an inventory of AI assets and shadow AI found through agentless integrations; red teaming with multi-turn attacks and validation of vulnerabilities; runtime guardrails that also address PII, PHI, credentials and secrets; and governance and compliance, including policy enforcement and compliance mapping. The vendor lists role-based access control and a SOC 2 Type II report. Deployment can be cloud, self-hosted or hybrid, including in the customer's own VPC with its own data and models.

Pillar Security is based in Tel Aviv, Israel, and was founded in October 2023, according to press coverage. Israel is outside the EU and EEA. The self-hosted and VPC option allows a European organisation to choose the region in which the platform and its data run. The sources consulted do not name hosting regions for the cloud version and do not describe an open-source edition.

Why digital sovereignty matters with Pillar Security

Pillar 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.

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

Pillar 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 Pillar Security together with your other vendors and gives a total score, a heatmap and the main risk drivers.
