Cybersecurity Consulting Firm – Cyber Castellum
Assess your cloud security posture and avoid expensive misconfigurations and data breaches.
As organizations shift critical workloads to the cloud, traditional security assumptions no longer apply. Misconfigurations, identity sprawl, and poor visibility can leave even compliant environments exposed.
Cyber Castellum helps you assess and strengthen your cloud security posture—whether you use AWS, Azure, Google Cloud, or a hybrid model. We evaluate your cloud controls against best practices like CIS Benchmarks, NIST CSF, and CSA CCM to identify weak points and reduce attack surface.
Every security control—from access restrictions to patching—depends on well-managed system configurations. Yet many organizations lack centralized oversight or consistent baselines across environments.
We assess your cloud platforms against leading security frameworks and provider-specific best practices, surfacing misconfigurations and risks.
We identify overly permissive roles, ineffective segmentation, and access risks in your cloud and enterprise environments.
Evaluate system settings against secure configuration benchmarks—whether on-prem, virtualized, or in the cloud.
Review of your policies, standards, and roles to ensure security is embedded in decision-making, not just documentation.
We test how well your governance translates to real-world implementation—bridging the gap between “what’s on paper” and “what’s in place.”
Receive practical guidance to mature your cloud governance model, strengthen accountability, and prepare for audit scrutiny or scaling operations.
