With its multi-layered defense approach, Semperis offers the industry’s most comprehensive security technology for hybrid AD and other identity systems, combined with incident response expertise.

The security-focused firm has grown rapidly, enabling it to launch its own partner program known as Vigilance. This allows other companies to benefit from the market position of Semperis by offering its solutions as part of an overall business model.

Semperis’ patented technology protects over 50 million identities from cyberattacks, data breaches, and operational errors. As it has become increasingly well-known, its qualities have been widely acknowledged, and is trusted to fend off cyber attacks by the likes of Hertz, Starbucks and Independence Blue Cross.
