Scope of work

What's in every audit

A systematic review across your entire IT environment — infrastructure, policies, people, and processes.

Network security assessment

Firewall rules, network segmentation, VPN configuration, and external exposure analysis.

Vulnerability scanning

Automated and manual scanning of all internal and external systems for known vulnerabilities.

Penetration testing

Ethical hacking to validate the real-world exploitability of discovered vulnerabilities.

Identity & access review

Privilege analysis, MFA coverage, and Active Directory / Entra ID configuration.

Compliance gap analysis

ISO 27001, CIS Controls, and sector-specific regulatory requirements.

Security policies review

Documentation, acceptable use, incident response, and business continuity plans.

Endpoint security audit

EDR coverage, patch levels, encryption status, and device management posture.

Cloud configuration review

Azure, AWS, and Microsoft 365 security settings, data residency, and access controls.

Phishing resilience test

Simulated phishing campaigns and staff awareness benchmarking.

AI-attack readiness

Where your existing controls handle AI-augmented threats (deepfake BEC, prompt injection of agent integrations, autonomous vuln-scanning) — and where they don't.

Sibling engagement

Concerned specifically about AI tool usage?

The Cybersecurity Audit covers AI-attack readiness in your existing controls. The AI Usage Audit goes deeper on what AI tools your employees are using and the data flowing through them.

Process

How an audit works

Structured, transparent, and minimally disruptive to your operations.

01

Discovery call

A direct conversation with a senior consultant — no forms, no sales team. We learn your environment, priorities, and compliance obligations.

02

Scoping & agreement

We define the audit scope, methodology, and timeline. You approve before we begin. No surprises.

03

Technical assessment

Remote and on-site testing across your agreed scope. Typical duration: five to ten business days.

04

Analysis & validation

Findings are validated, de-duplicated, and risk-scored against your specific business context.

05

Report & debrief

A full written report — executive summary and technical detail — plus a live debrief with the consultant who ran the assessment.

06

Remediation roadmap

A prioritised action plan you can act on immediately. We can also manage remediation as part of our managed services.
