Your network is the foundation everything else runs on. A weakness at the network level doesn't just expose one system — it can give an attacker access to all of them.
Crimson Wall's network penetration testing service simulates the techniques employed by real attackers to identify vulnerabilities in your network architecture, configuration, and connected devices. We don't stop at finding weaknesses — we demonstrate what an attacker could actually achieve with them in your specific environment.
What we assess
Perimeter Defences
Firewalls, DMZ configuration, external-facing services, and the robustness of your network boundary against external attack.
Internal Segmentation
Assessment of whether an attacker who gains internal access can move freely through your network or is constrained by effective segmentation.
Wireless Networks
Assessment of wireless infrastructure security as part of a holistic network security picture.
Remote Access & VPN
Security assessment of VPN gateways, remote desktop services, and other remote access solutions — a common initial attack vector.
What you get
- A realistic picture of what an attacker can achieve against your network
- Vulnerabilities ranked by actual exploitability and business impact
- Specific, actionable remediation guidance for your network team
- Evidence of security due diligence for regulatory bodies, insurers, and clients
- Insights that often improve both security posture and network performance
Internal vs. external testing: We offer both external network testing (simulating an outside attacker) and internal testing (simulating a compromised endpoint or malicious insider). Many organisations benefit from both perspectives.
