Test Your
Internal
Network
Defences
We simulate insider threats and lateral movement within your network to identify vulnerabilities that could be exploited by a compromised employee, contractor, or attacker who has breached your perimeter.
What We Test
Your Internal Network Infrastructure
Once inside your perimeter, attackers move fast. We test every layer of your internal network to find the paths they would take to reach your critical assets.
Active Directory & Domain Services
Testing AD misconfigurations, weak GPOs, Kerberos attacks, and privilege escalation paths that could give an attacker domain admin access.
Network Segmentation
Validating that network zones are properly isolated and that lateral movement between segments is restricted as intended.
Privilege Escalation
Identifying paths from standard user to administrator through misconfigured services, unpatched systems, and credential exposure.
Internal Services & Protocols
Testing SMB, RDP, SSH, database services, and internal web applications for weak authentication, default credentials, and known vulnerabilities.
Wireless Networks
Assessing Wi-Fi security including WPA2/3 configuration, rogue access points, evil twin attacks, and guest network isolation.
Credential & Password Security
Testing password policies, credential storage, and authentication mechanisms across the internal environment for weaknesses.
Why It Matters
Benefits of Internal Testing
Your perimeter is only one layer. Understanding what happens after a breach is critical to reducing business risk.
Expose Insider Threats
Discover what a malicious insider or compromised account could access, from file shares to domain admin.
Validate Network Segmentation
Confirm that sensitive systems like finance, HR, and production are properly isolated from general network traffic.
Identify Privilege Escalation Paths
Map the exact routes an attacker would take from a standard user account to full domain compromise.
Meet Compliance Requirements
Internal penetration testing satisfies requirements under Cyber Essentials Plus, ISO 27001, PCI DSS, and SOC 2.
Test Incident Detection
Validate whether your SIEM, EDR, and SOC can detect real attacker techniques like pass-the-hash, Kerberoasting, and lateral movement.
Reduce Blast Radius
Identify and fix the weaknesses that would allow a single compromised endpoint to escalate into a full network breach.
Our Process
How It Works
A structured, transparent process from scoping through to remediation support.
Scoping
We agree on testing scope, objectives, access levels, and rules of engagement for your internal environment.
Reconnaissance
Internal network mapping, service discovery, and enumeration of Active Directory, shares, and services.
Exploitation
Manual testing of identified weaknesses including privilege escalation, lateral movement, and data access.
Reporting
Detailed report with executive summary, attack paths visualised, and prioritised remediation guidance.
