Crosslayer Labs

Crosslayer Labs provides outside-in monitoring of customer Internet infrastructure to detect impersonation attacks against websites and APIs before they cause damage, comprehensively discovering and tracking dependencies across DNS records, BGP routing, TLS certificates, and JavaScript resources. The platform correlates security signals across these different layers of the network stack to identify patterns consistent with hijacking or spoofing attempts, then delivers actionable alerts that include root cause analysis and concrete remediation steps rather than raw, unprioritized data. Crosslayer Labs was founded by a team out of a Princeton University network security research lab whose founders previously invented Multi-Perspective Issuance Corroboration, a technique now adopted by every major certificate authority including Google, Apple, and Amazon to secure the issuance of HTTPS certificates protecting hundreds of millions of websites worldwide. The company applies that same multi-perspective philosophy to continuously protect organizations against the next generation of website and API impersonation threats.
