Tang is a free key management tool. Penta Security D.AMO Key Management System (KMS) is a commercial key management tool by Penta Security Inc.. Compare features, ratings, integrations, and community reviews side by side to find the best key management fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams protecting stateless services or ephemeral infrastructure in airgapped or hostile networks should choose Tang for its ability to bind decryption to network presence rather than individual credentials. The free, open-source model (670 GitHub stars) means you can deploy it without vendor lock-in and audit the binding mechanism yourself. Skip Tang if your threat model requires per-user key derivation or if your decryption clients can't maintain reliable network connectivity to a single Tang server; network presence is a weaker signal than possession for most cloud-native architectures.
Penta Security D.AMO Key Management System (KMS)
Enterprise security teams managing encryption keys across multiple database platforms will get the most from Penta Security D.AMO KMS because its dual-control architecture separates security administrator and DBA authority, eliminating single-points-of-failure in key access. The system covers the full NIST PR.AA identity and access control requirement through PKI-based authentication and role-based access controls, with support for Oracle, MSSQL, DB2, MariaDB, and PostgreSQL in a single deployment. Skip this if you need cloud-native key management or multi-region failover; D.AMO is strictly on-premises and built for organizations already committed to managing encryption infrastructure locally.
Tang is a network-based server that binds encrypted data access to network presence, allowing data decryption only when clients are connected to the specific network where the Tang server operates.
