Eclypsium Went Below the Operating System - and Found the Enterprise’s Soft Underbelly
Security teams learned to watch apps, identities, and operating systems. Eclypsium built a business around the layer underneath - the firmware and components everyone trusted because almost nobody could inspect them.
Binarly
Binarly is a firmware and software supply chain security company that reads the code no one else looks at - the layer below the operating system. Its AI-powered Transparency Platform analyzes firmware binaries to surface known and unknown vulnerabilities, malicious implants, misconfigurations and cryptographic weaknesses, then builds a genuine software bill of materials by reconstructing dependencies from the binary itself rather than trusting a manifest. Founded in 2021 by veteran reverse engineers Alex Matrosov and Claudiu Teodorescu, the company has disclosed hundreds of high-impact firmware vulnerabilities, including the widely covered PKfail Secure Boot flaw.

A Stanford Certified Project Manager, Castro is an operator's operator - the person who turns deep research and patented technology into enterprise revenue, partnerships, and trust with customers like Meta and Dell.
