Security Auditing

Protect your critical systems

Security auditing is a systematic examination of an organization’s information systems, processes, and policies to assess their security strengths, weaknesses, and overall effectiveness in safeguarding data and assets from potential threats.

The IT landscape of your organization – and therefore its cyber attack surface – can change dramatically within a short period of time, for instance, when you add new hardware, software or office locations.

For this reason, regular information security audits are an essential tool to ensure that your cyber defenses remain fit for purpose.

Our approach is holistic, aiming to cover various aspects of cyber security auditing and providing actionable insights to enhance an organization’s security posture. The goal is to assist in creating a robust defense against potential cyber threats while aligning with industry standards and regulations.

What we do

Whether you require a cloud security assessment, a build or a code review, our expert team can help.

We produce a comprehensive audit report with an executive summary and vulnerabilities listed in order of risk, with our remediation recommendations.

Cloud Security Audit - AWS, Microsoft Azure or Google Cloud Platform

Each cloud service has its own terminology and configurations, requiring a number of specific security checks – but overall, the audit process is similar .
Dionach will identify information assets such as instances, storage, identity management (Active Directory, IAM), databases, key vaults, and then carry out a comprehensive range of checks .

Build Review

Our auditing team carries out build reviews of standard operating system builds, either servers or endpoint, such as Windows 10, Windows Server, Linux servers or Mac OSX.

Build reviews are based on the appropriate standards such as the specific CIS Benchmark or the specific NCSC End-User Device Security Guidance.

We carry out a full range of checks on a server VM or endpoint build that you provide.

Code Review

Our consultants provide security reviews of the application code. We generally follow the OWASP code review guide. First, we determine the threats and context of the application and then we carry out a code review by sampling different areas of code to determine the effectiveness of a range of controls. The code review will involve both static analysis and manual review to identify potential vulnerabilities.

If required, we will review the code to determine compliance with the supplied or best practice coding standards, to ensure that the code can be maintained and supported.

Why Conduct Regular Security Auditing?

Highlight any vulnerabilities or weaknesses that put you at risk of a security breach.
Assess whether you have the necessary infrastructure and security policies in place – and whether those policies are being followed.
Identifying and fixing vulnerabilities proactively helps prevent security breaches.

Data Security and Protection Toolkit (DSPT) 2025/2026 CAF

The new DSPT for 2025/2026 is now more closely aligned to the NCSC Cyber Assessment Framework (CAF). This means more outcome-based auditing, focused on how well organisations achieve the intended security and governance goals. Organisations are required to have an independent audit assessment to the agreed CAF-aligned DSPT audit framework. Dionach can provide these independent […]

From Policy to Practice: Penetration Testing for ISO 27001

ISO 27001:2022 is the international standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). While the standard does not explicitly mandate penetration testing, it remains a critical supporting activity for demonstrating technical assurance and verifying the effectiveness of security controls. By incorporating regular, scoped, and risk-aligned penetration testing into their […]
