Verisign

Verisign operates some of the internet's most fundamental infrastructure. Founded in 1995 and headquartered in Reston, Virginia, the company runs the authoritative registry for the .com and .net top-level domains and, under an agreement with ICANN, performs essential root zone maintenance functions supporting the security, stability and resiliency of the global domain name system. It is publicly traded on Nasdaq under the ticker VRSN.

The company's proprietary DNS registration and resolution infrastructure handles billions of queries a day, connecting millions of users to websites worldwide. The .com registry has recorded 100 percent DNS uptime for more than 27 years, an operating record that reflects both engineering priorities and the reliability demands of a rising cyberthreat environment.

Technical work spans DNS and domain name registry infrastructure, DNS registration and resolution systems, DNSSEC, public-key cryptography, digital certificates and post-quantum cryptography, together with internet infrastructure security and resiliency more broadly. Verisign's history includes earlier work in public-key cryptography and digital certificate services.

Operations are global. The company is publicly traded and its engineering focus is on infrastructure built for dependability at internet scale.
