Not yet. MongoDB Atlas and self-managed MongoDB use TLS with classical key exchange for client connections. Data at rest uses AES-256 (quantum-resistant), but TLS transport encryption is vulnerable to quantum attack.
Key Takeaway: MongoDB is NOT quantum safe. Scan your MongoDB infrastructure with QScout to identify all TLS connections and key management dependencies. Enable encryption at rest (AES-256) as a baseline. Monitor MongoDB security advisories for PQC announcements.
MongoDB is NOT fully quantum safe today. **Current State:** MongoDB uses TLS 1.2/1.3 for client-to-server and replica set member connections. MongoDB Atlas encrypts data at rest using AES-256 (quantum-resistant). Client-side field-level encryption (CSFLE) and Queryable Encryption use classical key wrapping. **PQC Progress:** MongoDB has not publicly announced PQC migration plans: - **MongoDB Atlas**: Classical TLS for all connections. - **CSFLE**: Uses RSA or AWS/Azure/GCP KMS for key wrapping (classical). - **MongoDB drivers**: All use classical TLS. **HNDL Risk:** Database connections carry queries, results, and credentials. Intercepted MongoDB TLS traffic could reveal database schemas, query patterns, and actual data values. Database credentials transmitted over classical TLS are also at risk. **What Organizations Should Do:** Audit all MongoDB connections, replica set configurations, and Atlas peering configurations. Enable encryption at rest. Use QScout to discover all database cryptographic dependencies.
| Full Name | MongoDB and MongoDB Atlas |
| Category | database |
| Quantum Vulnerability | MongoDB TLS connections use classical key exchange (RSA/ECDH) vulnerable to quantum attack. AES-256 at-rest encryption is quantum-resistant. |
| NIST Status | MongoDB has not publicly announced alignment with NIST PQC standards. |
| Deprecation Timeline | MongoDB has not published PQC migration timelines. |
| Replaced By | MongoDB TLS will need to migrate to ML-KEM for key exchange when driver and server PQC support is available |
