Eclypsium provides security solutions focused on protecting hardware, firmware, and software infrastructure throughout the digital supply chain. The company was founded in 2015 by former Intel security researchers Yuriy Bulygin and Alex Bazhaniuk, who previously developed CHIPSEC, an open-source platform for hardware security assessment. The company's platform addresses vulnerabilities in infrastructure code that exist below the operating system level, including threats embedded in chips, firmware, and low-level code. Eclypsium's technology provides visibility into device supply chain risks that traditional security tools cannot detect, covering threats from manufacturing through deployment. The platform enables organizations to identify and mitigate security issues in critical hardware and firmware components across their enterprise infrastructure. This includes securing devices from BIOS and UEFI firmware to embedded controllers and other components that operate beneath traditional security layers. Eclypsium conducts independent security research on infrastructure vulnerabilities and shares findings publicly. The company serves enterprise customers who need to establish trust in their hardware and firmware supply chains, particularly for organizations with distributed device fleets and complex supply chain dependencies. The company's approach combines threat research with practical security tools designed to make infrastructure security manageable as part of standard IT operations rather than requiring specialized expertise for each assessment.
