Unified Security Posture Management Across External, Internal, and Cloud Attack Surfaces

Founded in 2016 and dual-headquartered in Seattle and Geneva, C2SEC sells a cloud-native Unified Security Posture Management platform to global enterprises, with a stated customer base of financial institutions, high-tech companies, insurers, and industrial conglomerates across North America, Europe, and APAC. The founding team comes out of Microsoft, IBM, and Swisscom, and the company reports backing from Sequoia, Microsoft for Startups, the F10/Tenity incubator, and the Trust Valley. The pitch is consolidation: replacing several point posture tools with one system of record.

The platform is organized as six modules feeding a correlation layer the company calls the Fusion Center. External Attack Surface Management performs agentless discovery of internet-facing IPs, domains, certificates, and shadow IT; On-Premise Scan runs inside the customer network through a Docker connector, combining CVE banner correlation with active vulnerability testing so scan data stays local; Continuous Exposure Validation runs safe automated exploitation to confirm which findings are genuinely reachable. Cloud and SaaS Posture cover AWS, Azure, GCP, Kubernetes, Microsoft 365, and Google Workspace.

The claimed differentiator is cross-domain correlation rather than module count. Fusion Center builds one classified asset inventory and maps attack paths spanning environments, treating an external exposure tied to an unpatched internal service as a single critical finding instead of two unrelated alerts, then prioritizes by exploitability and blast radius. Vendor Risk Management applies the same external scanning technology to third and fourth parties. Compliance mapping spans CIS, NIST, ISO 27001, SOC 2, PCI-DSS, DORA, NIS2, and CISA SCuBA baselines.
