Raised a $28M Series A (announced 2026-03-12) atop a $12M 2024 seed, bringing total funding to $40M.
Software is already used by Fortune 500 companies and named regulated customers Shutterfly and Tekion.
Series A closed 2026-03-12 with Bessemer Venture Partners, Picture Capital, and Red Dot Capital Partners, with plans to double headcount.
Extending endpoint monitoring to cover AI tool activity, not just human behavior, is a timely but incremental extension of existing endpoint-monitoring approaches.
Named enterprise customers in regulated industries is a positive signal, though no independent detection-efficacy benchmark was located.
Monitoring how both employees and AI tools interact with endpoints is an increasingly relevant concern as AI tool usage spreads across the enterprise.
Why CISOs Should Care
Bold Security monitors employee and AI-tool activity on enterprise endpoints in real time, aiming to rethink endpoint protection for a world where both humans and AI agents interact with corporate devices and data.
What Makes It Different
Explicitly extends endpoint monitoring to AI tool usage/activity alongside human employee behavior, rather than treating endpoint security as a purely human-behavior or malware-signature problem.
The Matrix Verdict
47/100 — EMERGING / UNRANKED
Fast-growing endpoint security vendor already used by Fortune 500 and regulated customers (Shutterfly, Tekion); reasonably substantiated for its stage given named customer references.
Editorial Note: Claims vs. Verified Findings
Funding, founder, and named-customer claims (Shutterfly, Tekion) verified via Calcalistech and Dealroom. Efficacy of the AI-tool-activity monitoring approach is vendor-described.
