In depth

A four-layer view of this service.

Context, scope, delivery and impact — written for buyers, boards, auditors and search engines alike.

Layer 01 — Context

Context & Why It Matters

01

Independent security audits are increasingly requested by boards, regulators, cyber insurers, prospective acquirers and enterprise customers as objective evidence that controls are designed and operating effectively.

  • Unlike a certification audit (which only tests against the chosen standard), a MAST security audit is tailored to the baseline most relevant to the audience — ISO 27001 Annex A, NIST CSF 2.0, CIS Controls v8, CBUAE, SAMA, NCA ECC or a custom hybrid.
Layer 02 — Scope

Scope & What It Covers

02

Coverage typically spans governance, risk management, asset management, identity and access management, data protection, network security, endpoint and server security, cloud security (AWS, Azure, GCP), application security and SDLC, vulnerability and patch management, security monitoring and incident response, third-party risk, business continuity and physical security.

  • The depth of testing — design, implementation or operating effectiveness — is agreed upfront.
Layer 03 — Approach

Our Approach & Delivery

03

Lead Auditors (ISO 27001 LA, CISA, CRISC) execute a four-stage engagement: scope, fieldwork, report and validate.

  • Fieldwork combines interviews with system owners, documented evidence review, configuration sampling, log review, control walkthroughs and limited technical testing.
  • Findings are risk-rated using a documented methodology (likelihood × impact), with clear root-cause analysis and prioritised remediation.
Layer 04 — Impact

Business Impact & Outcomes

04

An independent, written report suitable for the board, audit committee, regulator, insurer or customer — typically delivered in 4–8 weeks.

  • Findings drive a remediation roadmap with owners and timelines; high-risk findings are usually closable within 90 days.
  • Re-test of remediated findings is included so the report can be re-issued as a clean attestation.

What auditors and regulators expect to see.

What an independent security audit produces — the artefacts the board, regulator or customer will expect to see.

    Baseline (ISO 27001 Annex A / NIST CSF / CIS / CBUAE / NCA ECC), systems and locations agreed in writing.

  • Evidence sampling plan

    Risk-based sampling across people, process and technology controls.

  • Control walkthroughs and tests

    Interview notes, screenshots, configurations and log extracts retained.

  • Risk-ranked findings register

Independent assurance signal

Faster customer security reviews

Replaces dozens of bespoke questionnaire responses.

Pre-certification confidence

Surfaces gaps before a formal certification audit starts the clock.

Benchmarking

Maturity score comparable to peers in the same sector and geography.

FAQ

Frequently asked questions.

Is this the same as a penetration test?+

No. A security audit reviews controls, processes and evidence; a penetration test actively exploits technical weaknesses. Most clients run both.

How long does a security audit take?+

Typically 4 to 8 weeks: 1 week scoping, 2 to 4 weeks fieldwork, 1 to 2 weeks reporting, with re-test on demand.

Which baseline should we audit against?+

Choose the framework your stakeholders care about — ISO 27001 Annex A for certification audiences, NIST CSF 2.0 for board / US buyers, CIS Controls for technical baselining, CBUAE / SAMA / NCA ECC for regulator submissions.

Are your auditors independent?+

Yes — auditors are ring-fenced from implementation engagements with the same client to preserve independence. Where we have implemented, a separate firm performs the certification audit.

Will the report be acceptable to our customers?+

Yes — our reports are accepted by enterprise procurement, insurers and regulators. We provide an executive summary that can be shared under NDA.

Can you audit our cloud environment?+

Yes — AWS, Azure, GCP and OCI configuration audits aligned to CIS Benchmarks and the CSA CCM are part of our standard offering.

Do you provide a remediation team?+

Optional. Many clients prefer their own team to remediate with our methodology guidance; others retain us for fixed-fee remediation.
