Cloud Security Architecture

Cloud security is not a configuration review. It is an ongoing operational discipline — managing IAM permissions that drift over time, tuning security services that require interpretation to be useful, and building the monitoring pipelines that tell you when something is wrong before a breach occurs. Axiom Sovereign builds and hardens cloud security architectures in AWS, Azure, and Google Cloud, then transfers a documented, operational system to your team.

What We Build

Cloud Security Assessment

Configuration review across IAM, network security, data protection, logging, and monitoring. Findings mapped to CIS Benchmarks or CSA Cloud Controls Matrix. Prioritized remediation plan.

IAM Architecture Build

Least-privilege IAM policy design and implementation. Service account hardening. Privileged access controls. Just-in-time access for administrative functions. Permission boundary implementation.

Security Service Configuration

AWS: GuardDuty, Security Hub, Config, CloudTrail. Azure: Defender for Cloud, Sentinel, Policy, Monitor. GCP: Security Command Center, Cloud Audit Logs. Tuned for your environment, not default settings.

Misconfiguration Remediation

Direct remediation of identified misconfigurations — not a findings report, but hands-on implementation. Public S3 buckets locked down. Overly permissive security groups corrected. Encryption enabled.

Monitoring and Alerting

Security event monitoring pipeline built and tuned. Alerts configured for high-signal events: IAM changes, large data exports, failed authentication patterns, public resource exposure.

Architecture Documentation

Documented cloud security architecture: what controls are in place, how they are configured, what they detect, and how to maintain them. Your team inherits an operational system with full documentation.

Framework Alignment

Cloud security engagements are aligned to established industry benchmarks and frameworks, producing documentation that satisfies audit and compliance requirements:

CIS Benchmarks (AWS, Azure, GCP) — Configuration baseline hardening against CIS Level 1 and Level 2 controls
CSA Cloud Controls Matrix (CCM) — Cloud-specific security controls aligned to CCM v4
NIST CSF 2.0 — Cloud security implementation mapped to CSF Protect and Detect functions
NIST SP 800-144 — Guidelines on security and privacy in public cloud computing
