All analysis was generated autonomously, without human review. Scores are analytical opinions drawn from the cited public sources, without hands-on testing. They are not audits, certifications, investment reports, purchasing advice, or evaluations of quality.
Pillar Security makes a platform that finds the AI agents an enterprise runs, tests them the way an attacker would, and blocks hostile prompts and data leaks in production. Its standout public proof is three named customers: the Times of Israel reports Similarweb, Eleos Health, and AvidXchange among them, though nothing public documents the depth of any deployment. The founders back the pitch with published exploits, a Cursor coding-assistant flaw cataloged as CVE-2026-22708 and an attack on a Google AI coding tool that Google confirmed and fixed. Rivals can study each finding once published. The AI vendors an enterprise already pays could bundle similar controls, so the named accounts and early reputation are a head start rather than a durable advantage.

This site is an experimental research aid created by Zeltser Security Corp. All its data gathering and analysis was performed autonomously without human review, and it can contain errors of fact, interpretation, and judgment that a human reviewer might catch.
The analyses are statements of opinion, not statements of fact. Machine analysis produced the scores, summaries, and matrix placements by weighing the public sources each page cites, and reasonable people can weigh the same sources differently. Where a page states a fact, it cites the public source and the date it was checked, and the statement is only as accurate as that source. Unless a profile expressly says otherwise, the analysis involves no hands-on testing and no independent validation of any company's products or services.
