Silverfort is on a mission to bring identity security everywhere, and allow organizations to operate without fear or disruptions. Fueled by a belief that enterprises and their identity teams deserve better, we found a way to break down the silos of identity security—eliminating the critical gaps and blind spots left behind by a patchwork of point solutions. After years of research, we found a way to break free from these limitations. Silverfort created the only end-to-end identity security platform that secures all identities—humans and machines, on-prem and in the cloud. Our patented Runtime Access Protection (RAP) technology seamlessly integrates with the entire IAM infrastructure and secures it from within with unmatched visibility, analysis, and inline enforcement of security controls. This innovative approach brings protection to all resources in all environments, including ones that were previously impossible to secure, such as legacy systems, service accounts, command-line tools and IT/OT infrastructure. Finally, enterprises can stay ahead of the evolving identity threats, minimize their attack surface, stop breaches before they can spread, close compliance gaps, and break free from countless limitations and endless efforts. Silverfort is the identity security platform the industry deserves, earning us the trust of more than 1,000 leading organizations, including several Fortune 50 companies.  This is identity security done right. Join Silverfort, and be part of a team that’s pushing the boundaries of identity security—no compromises, no blind spots, no limits.
