- Maintain audit trail for regulatory reporting
Government Contracts (CMMC, FedRAMP)
If pursuing government customers:
- CMMC (Cybersecurity Maturity Model Certification): Required for Department of Defense contractors
- FedRAMP: Required for cloud services used by federal agencies
Both build on SOC 2 foundation but add specific requirements.
Privacy Regulations (GDPR, CCPA)
If handling personal information:
- Implement Privacy Trust Service Criteria
- Data subject rights (access, deletion, portability)
- Privacy impact assessments
- Data processing agreements
Future-Proofing: Preparing for Quantum Threat to Cryptography
While not directly related to SOC 2, forward-thinking quantum startups should prepare for post-quantum cryptography:
- Monitor NIST post-quantum cryptography standards
- Plan migration from RSA/ECC to quantum-resistant algorithms
- Implement crypto-agility (ability to swap algorithms)
This demonstrates security maturity and may be a customer differentiator.

Achieving SOC 2 compliance as a quantum computing startup requires adapting traditional security frameworks to the unique challenges of quantum technology. By implementing robust controls around quantum IP protection, multi-tenant quantum hardware access, processing integrity, and availability, you not only satisfy audit requirements but build a genuinely secure and reliable quantum platform.
SOC 2 certification signals to enterprise customers that you take security seriously and have the operational maturity to handle their most sensitive quantum workloads. In the competitive quantum computing landscape, this trust is invaluable.
The quantum future is bright—and secure.
