Our Services

Cybersecurity Compliance Assessments & Audit Consulting

We help organizations prepare for, navigate, and succeed in regulatory and third-party compliance audits without the guesswork.

Compliance Assessments & Audit

Independent, Objective, Audit-Ready.

In today’s regulatory landscape, audits are not optional—they're expected. Whether mandated by your client, industry, or a government contract, failing to meet compliance requirements can halt business, trigger penalties, or damage reputation.

At Cyber Castellum, we offer expert-led compliance assessments that benchmark your existing cybersecurity controls against recognized standards such as NIST 800-53, CMMC, HIPAA, PCI-DSS, ISO 27001, and SOC 2. We don’t just run through a checklist—we deliver tailored insights, prioritize your gaps, and help you prepare to pass any audit with confidence.

OUR TRUE WORDS

Why Prepare With Us? Because Failure Isn’t an Option.

Third-party audits can be stressful—but not if you’re prepared. Our assessment approach is built for transparency, actionability, and audit success.

  • Understand your posture against multiple compliance frameworks
  • Receive audit-style evaluations from experienced security consultants
  • Fix the gaps before your auditors find them
  • Build trust with regulators, clients, and business partners
  • Achieve certified, defensible results—backed by documentation
  • Get expert support before, during, and after your audit engagement
