Who it fits
From its own pages, the company sells mainly to organisations that want to extend their own team with a 24/7 Security Operations Center. Its industry pages speak of protecting insurance operations, defending financial services, defending patient data and clinical operations, protecting portfolio companies, and stopping threats before they disrupt production. The pages also say Atlas connects to any signal across your current security tools, which reads as a fit for teams that already run security tools. The security operations center entry names boards, regulators, and cyber insurers as parties that require a human accountability layer.Our reading is that the pages address teams that need evidence-backed exploitability confirmation rather than severity scores. The pages point to organizations running Validated CTEM programs. The pages point to organizations managing cyber risk in subsidiaries and in M&A deals, including before a deal closes.
