Vigilant is an identity intelligence platform designed for data center environments. It unifies IAM roles, physical access controls, device behavior, and environmental conditions into a continuous identity view — referred to internally as "Truman Identities" — covering the full scope from perimeter to core infrastructure. The platform correlates identity signals with operational and environmental data (power, cooling, sensors, incident activity) to surface anomalies before they affect service. It detects irregularities such as shared credentials, off-path movement, and after-hours access activity across data center zones including co-location facilities, enterprise and private data centers, hyperscale operations, and restricted IT areas. Vigilant generates correlated, normalized access logs and audit trails designed to support compliance with SOC 2, ISO 27001, PCI-DSS, and Zero Trust frameworks. It is designed to integrate with legacy systems without requiring full replacement, allowing incremental modernization of existing security infrastructure. The platform is part of a broader Secure Passage solution suite that includes Dragon (a log normalization and data engine), Strategic Services (consulting for IAM and physical access integration), and Behavioral Threat Assessment (insider risk detection tooling).
