About Xeol

Pronounced Zee-O-L. End-of-life (EOL) and outdated software are a black box of vulnerabilities with very limited remediation paths. These 2 factors combine to make managing them a necessary proactive practice. Xeol enables enterprises and Fortune 500s to create a proactive EOL management program that directly contributes to better vulnerability management and lower cyber insurance.
