SOC 2 readiness audit

Assessment of controls against the Trust Services Criteria to identify gaps before your SOC 2 Type I or Type II examination.

Review of data protection controls, processing activities, consent mechanisms and documentation against UK GDPR and GDPR requirements.

Custom framework audit

Internal audit against any framework or bespoke control set, including Cyber Essentials, NIST CSF, PCI DSS and sector-specific requirements.

Use cases

When to commission an internal audit

Internal audits are a mandatory requirement for most certification frameworks, and a valuable tool for continuous improvement beyond compliance.

Pre-certification readiness

Identify control gaps before your external certification audit to avoid surprises and reduce the risk of non-conformities.

Annual surveillance audit preparation

Prepare for ISO 27001, SOC 2 or other annual surveillance audits by validating that controls remain effective and evidence is audit-ready.

Board and audit committee assurance

Provide independent assurance to your board or audit committee that information security controls are operating effectively.

Post-incident review

Following a security incident or near-miss, an internal audit validates that root causes have been addressed and controls strengthened.

Regulatory compliance validation

Demonstrate to regulators, customers or partners that your controls meet the requirements of applicable frameworks and regulations.

Continuous improvement programme

Embed regular internal audits as part of your ISMS or compliance programme to drive ongoing improvement and maintain certification.

Process

How we conduct internal audits

A structured, evidence-based audit methodology that delivers findings your team can act on and your auditors will accept.

01

Scope definition and planning

We agree the audit scope, objectives, methodology and timeline. You receive a formal audit plan for sign-off before fieldwork begins.

02

Evidence collection

We request and review policies, procedures, system configurations, logs and other evidence to assess control design and implementation.

03

Control testing

We test the operating effectiveness of controls through interviews, walkthroughs, sample testing and technical inspection.

04

Gap analysis and risk rating

We identify control gaps and weaknesses, rate each finding by risk severity and map them to your framework obligations.

05

Draft report and management response

We issue a draft report for management review. You provide responses and agree remediation actions before the final report is issued.

06

Final report and follow-up

We issue the final audit report and schedule a follow-up review to track progress against the management action plan.
