How does Internal Network Pen Testing work?

Internal Network Penetration Testing works by our team simulating cyberattacks against an organisation's internal network infrastructure to identify vulnerabilities and weaknesses. It involves assessing the security controls, configurations, and architecture of internal networks, including servers, workstations, and other network devices. Through a combination of manual testing and automated scanning, potential vulnerabilities are uncovered and prioritised for remediation. Testing can be completed by plugging a device into the local network, accessing the local network via a VPN, or our test team can be made available to visit the test site (additional cost).
