Exostar builds secure collaboration and risk management infrastructure for industries where a breach isn't an inconvenience - it's a regulatory event or a national security concern. Founded in 2000 and headquartered in Herndon, Virginia, the company operates across aerospace and defense, life sciences, healthcare, and consumer services. Its platform serves over 150,000 organizations, including 10 of the 20 largest pharmaceutical companies. The threat model here is supply-chain trust: how do you let thousands of external partners access shared systems without creating an identity sprawl problem that attackers can exploit?
The technical stack centers on identity and access management delivered as cloud services. The Managed Access Gateway (MAG) is the core IAM layer - a secure, cloud-based service that federates authentication across organizational boundaries. The broader Exostar Platform wraps that identity foundation into digital transformation tooling, enforcing compliance and trust guarantees for regulated workflows. This is identity-first security architecture applied to multi-enterprise collaboration at scale.
For security engineers, the draw is specificity: these aren't generic enterprise IAM deployments. You're dealing with CMMC compliance requirements in defense, GxP validation in pharma, and HIPAA constraints in healthcare - all simultaneously, across a partner ecosystem that can't be walled off. The work lives at the intersection of zero-trust principles, cloud-native platform engineering, and regulatory domain expertise.
