Identifies and remediates non-quantum-safe cryptographic configurations in Azure including classical TLS key exchange, RSA and ECC keys in Key Vault, and classical certificate algorithms. Maps findings to NIST PQC standards FIPS 203, FIPS 204, and FIPS 205. Use when assessing quantum readiness of Azure infrastructure or building a Cryptographic Bill of Materials.
Queries Azure Monitor activity logs and sign-in logs to detect suspicious administrative operations, impossible travel, and privilege escalation.
Detect abnormal access patterns in Azure Blob Storage by analyzing Storage Analytics and diagnostic logs. Identifies after-hours bulk downloads, access from new IP addresses, unusual API calls (GetBlob spikes), and potential data exfiltration.
Auditing Microsoft Entra ID (Azure Active Directory) configuration to identify risky authentication policies, overly permissive role assignments, and guest user risks.
Conduct cloud security audits using Center for Internet Security (CIS) benchmarks for Azure. Covers interpreting CIS Foundations Benchmark controls, running automated assessments, and maintaining continuous compliance monitoring.
Establish SAML 2.0 identity federation between on-premises Active Directory and Microsoft Entra ID (Azure AD) for seamless cross-domain authentication and SSO.

OpenShield identifies gaps in the logging required for an effective SIEM:
AZ-STOR-004 (Diagnostic Logs), AZ-IDN-009 (Role Assignment Alerts)AZ-IDN-007 (MFA Status), AZ-IDN-002 (Conditional Access)Enable Microsoft Sentinel on a Log Analytics workspace.
Ingest Entra ID Sign-in/Audit logs and Azure Activity logs.
Example: Detect impossible travel or mass resource deletions.
Use Logic Apps to automatically disable compromised Entra ID accounts.
