rThreat is a cybersecurity company that develops a platform for the evaluation and validation of cybersecurity solutions using real-world threat artifacts. The platform provides clients with an on-demand testing environment that operates within their existing corporate security infrastructure, enabling organizations to assess how their defenses perform against both known and unknown threats. A distinguishing aspect of rThreat's approach is its use of real known and unknown zero-day artifacts — malicious samples not yet publicly disclosed or patched — to simulate genuine attack scenarios. This allows security teams to measure how their existing cybersecurity tools and processes respond to advanced and novel threats, rather than relying solely on simulated or sanitized test data. The company incorporates artificial intelligence into its evaluation methodology to support the assessment of cybersecurity systems and solutions. rThreat also develops test-oriented unknown artifacts specifically designed for stress-testing security controls, positioning this capability as a core differentiator in its offering. rThreat's target market includes companies and institutions seeking a pragmatic, evidence-based approach to validating their security posture. The platform is intended for use by security professionals who need to verify the effectiveness of their defensive tools and operational processes against realistic threat scenarios, including targeted attacks. The company is headquartered in Bellingham, Washington, USA.
