Network & IT Security Audits
An independent review of your network, systems and controls: what an attacker could reach, what is misconfigured, and what to fix first, mapped to NIS2, ISO 27001 and GDPR.
What are Security Audits?
A security audit is a systematic evaluation of your company's information system, measuring its conformance against established criteria. These criteria can include internal policies, legal regulations, industry standards, and cybersecurity best practices.
Key Areas We Assess
- Security Policies & Procedures
- Access Control Management
- Vulnerability Assessment
- Network Security Analysis
- Compliance Verification
What a network security audit covers
Every audit is scoped to your environment, but most cover the same core areas. This is the checklist we work through.
Perimeter and firewall rules
Exposed services, firewall and ACL rules, egress filtering, and anything reachable from the internet that shouldn't be.
Network segmentation
VLANs and trust zones: whether a compromised laptop can reach servers, backups or OT systems it has no business touching.
Remote access and VPN
VPN and RDP exposure, MFA coverage, and the access paths your vendors use.
Identity and Active Directory
Privileged accounts, password policy, stale accounts, and the common AD misconfigurations attackers use to escalate.
Vulnerabilities and patching
Authenticated vulnerability scanning of servers, endpoints and network devices, and how quickly patches actually land.
Wireless networks
Encryption, guest network isolation and rogue access points.
Logging and detection
Whether the logs an investigation would need exist, are retained, and are watched by anyone.
Backup and recovery
Whether backups are offline or immutable, tested, and out of an attacker's reach.
Email security
SPF, DKIM and DMARC, and how phishing and spoofed mail are filtered.
Cloud configuration
Microsoft 365, Azure, AWS or Google Cloud settings that widen your attack surface.

Audit, vulnerability scan or penetration test?
| Service | What it answers | When to choose it |
|---|---|---|
| Vulnerability scan | Which known vulnerabilities and misconfigurations exist | Continuously, as hygiene between deeper reviews |
| Security audit | How your network, controls and processes measure up against good practice and regulation | First, when you need the full picture, or before NIS2 or ISO 27001 work |
| Penetration test | What an attacker could actually achieve by chaining weaknesses | Before a system goes live, after major changes, and at least yearly |
Network security audit FAQ
How often should we audit our network?
At least once a year, and after any major change: a new site, a cloud migration, a merger or a security incident. Organisations in scope of NIS2 should tie audits to their risk assessment cycle.
How long does an audit take?
It depends on scope: the number of sites, servers and cloud services. We give you a timeline together with the quote.
Will the audit disrupt our operations?
No. Scans are scheduled and throttled together with your team, and anything that could touch production is agreed in advance.
How much does a network security audit cost?
It depends on the size of the environment and how deep the testing goes. We quote once we understand your scope: sites, systems and cloud services.
Does an audit make us NIS2 compliant?
An audit shows where you stand and what to fix. Compliance comes from putting those fixes in place along with the processes NIS2 requires, such as risk management and incident reporting. We help with the technical side of both.
Does an audit include a penetration test?
An audit covers vulnerability scanning and configuration review. Where the scope calls for it, it can be extended with manual penetration testing of selected systems.
