NSS Labs

NSS Labs LLC provides continuous control validation for cybersecurity and AI systems, supporting governance, risk, and compliance programs. Originally founded in 2007 as NSS Labs, Inc., the company built a reputation for independent, evidence-based testing of security products against real-world threats. After ceasing operations in 2020, it re-emerged in 2025 as NSS Labs LLC, a privately held company operated by its executive team. The company's core offering is Minion by NSS Labs, an AI-enabled continuous control validation platform that performs automated, real-world testing of cybersecurity controls and AI systems at scale. The platform evaluates security effectiveness using a test infrastructure that includes over 4,000 exploits, more than 1,000 evasion techniques, and over one million malware samples updated daily. These are combined dynamically to simulate realistic attack scenarios, including exploits, malware, evasions, and false positives. NSS Labs targets enterprises, service providers, and security vendors seeking data-driven validation of their security tooling, moving from periodic point-in-time assessments to continuous, measurable testing. The company's leadership includes veterans of the original NSS Labs and founders of CyberRatings.org, a related nonprofit focused on cybersecurity product testing and ratings.
