Temporal Cloud offers a secure and efficient solution for orchestrating mission-critical workflows while maintaining high levels of data privacy and security. It prevents data exposure by encrypting sensitive payloads within the user's environment and ensuring no inbound connectivity is required, as workers communicate with Temporal over outbound HTTPS connections. Key features include mutual TLS secured with client certificates from the user's Certificate Authority, role-based access control, and private connectivity options through AWS PrivateLink or Google Cloud Private Service Connect. Temporal's design supports compliance with standards like SOC 2 Type II, HIPAA, and GDPR, and provides operational defense through SSO-gated access, regular audits, and penetration testing. By maintaining data and code within the user's environment and offering secure debugging tools, Temporal ensures that enterprises can run sensitive workflows without compromising speed or security, ultimately reducing risk and facilitating faster, secure deployment of business applications.
