Internal Infrastructure Penetration Testing

Once inside your network—whether through phishing, social engineering, or compromised credentials—attackers can move laterally to access sensitive systems and data. Internal infrastructure penetration testing helps uncover these hidden weaknesses, simulating real-world attacks to reveal where your internal defences need strengthening.

We’re Specialist

Why It Matters

Internal threats—whether from malicious insiders or external attackers who breach perimeter defences—can have severe consequences. Our CREST-accredited testers assess your internal infrastructure to detect misconfigurations, insecure systems, and access control flaws before they can be exploited.

What You’ll Gain

01

Reveal Hidden Vulnerabilities

Gain visibility into insecure or unpatched systems, weak protocols, and poorly configured services that attackers could exploit to gain deeper access.

 

02

Enhance Access and Identity Controls

Strengthen internal authentication processes, protect privileged accounts (such as domain admins), and guard against password cracking, brute-force attempts, and lateral movement.

 

03

Protect Sensitive Data and Systems

Prevent unauthorised access to mission-critical information, detect pathways that allow attackers to persist undetected, and secure internal communications and file transfers.

What is Internal Infrastructure Penetration Testing?

Internal infrastructure penetration testing simulates an attacker who already has internal access to your environment—whether via a compromised laptop, malicious employee, or phishing victim. The goal is to identify weaknesses that could be used to:

01

Escalate privileges

02

Move laterally across your network

03

Bypass internal controls and monitoring

Our testing combines manual techniques and advanced tooling to replicate real-world internal threats, providing actionable insight to close security gaps and protect your organisation from within.
