The ousted founder and chief executive of online information service Individual Inc has turned up ValiCert a small private company developing products and services said to validate and prevent the misuse of digital certificates. Yosi Amram is now president and chief executive of Sunnyvale, California-based ValiCert Inc having been entrepreneur-in-residence at venture capitalists Draper Fisher Jurvetson. ValiCert’s products will enable certificate issuers to revoke certificates that have been compromised, will enable applications to check the validity of certificates before accepting them; and let users obtain proof of the validity of their certificate and present it, along with their certificate, to applications. There are two products, the ValiCert Validation Server, which revokes certificates and the ValiCert application toolkit, which adds the ability to check the validity of a certificate to applications such as email, browsers, and brokerage trading applications. Applications get certified by contacting a ValiCert-enabled certificate server directly or through the ValiCert Certificate Validation Service. The products are in limited beta right now with developers and public key infrastructure vendors. Amram was pushed out as chief executive by Individual’s board last July.
