Protect, monitor and defend your Internet presence
Crosslayer Labs detects impersonation attacks on websites and APIs. We provide "outside-in" monitoring of customer infrastructure, comprehensively discovering and monitoring all Internet dependencies, including DNS, BGP, TLS certs, Javascript. We correlate signals from different layers of the Internet stack to identify attack patterns. Our alerts are actionable and contain root cause analysis/remediation recommendations. Our founding team is world renowned for previously inventing the MPIC standard adopted by all the major CAs including Google, Apple, Amazon. The MPIC standard is securing over 700 million websites via the issuance of over 3 billion digital certificates, and is now a global internet standard that protects every single HTTPS connection.
Crosslayer Labs provides protection, monitoring, and defense for web infrastructure, focusing on securing websites and APIs through ongoing threat detection and attack surface analysis. It emphasizes multi-layer security intelligence and first-party/third-party monitoring to prevent breaches and hijacks.
The platform discovers and analyzes the attack surface of APIs and web services, monitors and correlates attack signals across network layers, and delivers security analytics and ongoing monitoring to detect and mitigate threats. It leverages multi-layer threat correlation to proactively identify patterns and provide rapid response and mitigation.
Who it’s for: Enterprises and organizations with web infrastructure relying on HTTPS, APIs, and online services that require continuous protection and threat detection across multiple network layers.

I am am innovator in web and network security. I invented Multi-Perspective Issuance Corroboration (MPIC) which now secures every single HTTPS connection. I am currently focusing on building the Crosslayer Labs platform for web resource integrity.
I'm a recent PhD graduate from Princeton and security researcher. I've worked with the CA/Browser Forum to turn my research on TLS certificate security into ecosystem-wide requirements which now improve the security of every HTTPS connection you view in your browser. Before starting Crosslayer with my long-time research collaborators, I was a visiting research at Google and Corelight Labs.
I am a professor at Princeton University and co-founder of Crosslayer Labs (YC W26). I specialize in the field of cybersecurity/privacy and am the recipient of the ACM Grace Hopper Award. My research has helped secure every single web connection (HTTPS) worldwide and enhanced the security of deployed LLMs (e.g., GPT 3.5 and GPT4V at OpenAI).
TLS certificates no longer guarantee website authenticity. We built Crosslayer Labs to stop hackers from stealing user credentials.
Crosslayer Labs detects attacks that impersonate websites and APIs by monitoring a domain’s entire network stack to identify hijack attempts. The company, built by researchers who previously helped secure HTTPS at scale, offers MPIC-based certificate corroboration to defend against credential theft and site impersonation for high-risk sectors like fintech, banking, and health care.
