Virsec Systems

Virsec Systems is a San Jose, California-based cybersecurity company founded in 2015, specializing in workload protection and patchless vulnerability mitigation for critical applications and software supply chains. The company's flagship product, OTTOGUARD.AI, uses patented zero-trust technology to autonomously neutralize both known and zero-day threats at runtime — without requiring patching — achieving zero Mean Time to Remediate (MTTR). Virsec protects against ransomware, memory-based attacks, and software supply chain compromises by locking down workloads in milliseconds, providing complete visibility into deployed software, and continuously enforcing integrity. The platform addresses the 'patch treadmill' problem facing security and application teams, reducing exploitable vulnerabilities by up to 90% and eliminating the need for emergency patch cycles and downtime. Virsec serves enterprise customers across industries handling legacy and mission-critical software environments.
