Is SAP Quantum Safe?
Not yet. SAP has acknowledged the quantum threat and initiated research into post-quantum cryptography, but SAP S/4HANA, SAP BTP, and SAP cloud services have not completed the transition to PQC algorithms.
Key Takeaway: SAP is NOT quantum safe. Scan your SAP landscape with QScout to discover all cryptographic dependencies including RFC, SNC, and API connections. Prioritize SAP data with long-term confidentiality requirements.
- Modality
- SaaS Platform
- Vulnerability
- SAP TLS and SNC connections use classical cryptography vulnerable to quantum attack. SAP data often has decades-long confidentiality requirements amplifying HNDL risk.
- NIST status
- SAP has acknowledged PQC but has not publicly confirmed NIST FIPS 203/204/205 adoption timelines for production services.
- Replaced by
- SAP communication protocols will need to migrate to ML-KEM and ML-DSA when PQC support is available
- Deprecation
- SAP has not published firm PQC migration timelines for cloud or on-premises products.
Technical Analysis
SAP is NOT fully quantum safe today.
Current State
SAP uses TLS 1.2/1.3 for cloud service connections, RFC/SNC for on-premises communication, and X.509 certificates for authentication. SAP Cloud Platform Identity Authentication uses classical cryptography.
PQC Progress
SAP has shown awareness of the quantum threat:
- SAP Security Research: Has published PQC research and participated in industry discussions.
- SAP CommonCryptoLib: The core crypto library used across SAP products — PQC integration status is not publicly confirmed.
- SAP BTP: Business Technology Platform uses classical TLS.
- SNC (Secure Network Communications): On-premises SAP connections use classical algorithms.
HNDL Risk
SAP systems contain core business operations data: financial records, supply chain data, manufacturing processes, customer data, and trade secrets. Much of this data has 10-30 year confidentiality requirements, making HNDL risk severe.
What Organizations Should Do
Audit all SAP connections including RFC, SNC, IDoc, BAPI, and OData/REST API integrations. Identify SAP data with long-term confidentiality requirements. Use QScout for comprehensive SAP cryptographic surface discovery.
