Beyond the Perimeter

Your Internal Network Is Your Operational Core

An organisation's internal network and related services form its operational core. While internal network assessments are frequently conducted after external assessments as part of a layered security strategy, they remain critically important rather than secondary.

A defence-in-depth approach ensures that if any single security control fails—whether on the network perimeter or at any internal host—additional controls can mitigate, prevent, or detect malicious activity. Organisations commonly maintain strong external security while leaving internal networks vulnerable, creating what's often described as a “hard shell with a soft centre.”

Internal network assessments address this imbalance by providing realistic insights into the security posture once an external breach has occurred.

What happens if an attacker bypasses your external defences?

This assessment answers that crucial question. Understanding this scenario allows organisations to strengthen controls throughout their infrastructure rather than relying solely on perimeter protection.

Don't rely on a hard shell alone.

Why It Matters

What Sets Us Apart

Real-World Testing by Qualified Experts

Using proven methodologies and an attacker’s mindset, we assess your internal network from both authenticated and unauthenticated perspectives. This dual approach reveals genuine vulnerabilities in your organisation’s internal threat landscape.

Reduced Risk

Comprehensive assessments identify security issues before malicious actors do. Our internal infrastructure reviews can be tailored to focus on mission-critical networks that underpin your core business functions.

Systematic Approach

We combine industry-recommended practices for consistent, reproducible results with custom, experience-led activities that demonstrate real-world risk scenarios.

Internal Assessment Questions

An internal infrastructure assessment evaluates the security of your internal network, servers, and services from the perspective of an attacker who has already bypassed your external defences. It identifies vulnerabilities that could be exploited to move laterally, escalate privileges, or access sensitive data.

While external penetration tests focus on perimeter defences visible from the internet, internal assessments simulate threats from within your network—such as a compromised employee device, a rogue insider, or an attacker who has breached the perimeter. Both are essential components of a layered security strategy.

We recommend conducting internal infrastructure assessments at least annually, or whenever significant changes are made to your network architecture, systems, or security controls. Regular assessments ensure that new vulnerabilities are identified and addressed promptly.

Assessments cover Active Directory, internal servers, databases, network segmentation, wireless networks, file shares, internal web applications, and any other services accessible within your network environment.

Our assessments are designed to minimise operational impact. We work closely with your team to schedule testing during appropriate windows and use controlled techniques that avoid service disruption while still providing thorough coverage.
