Internal Network Pentest
With an internal network pentest we test the resilience of your internal network, servers and workstations, the way an attacker who is already inside would. Think of someone who obtained login credentials through phishing, or a vulnerable workstation that serves as a stepping stone to critical systems.
An IT landscape often consists of multiple parts, such as a mobile app or website. In a no-obligation introductory conversation we determine the right scope together, so the pentest fits your situation exactly.

[ 01 ]Vulnerabilities
Example internal network vulnerabilities
The goal of an internal network pentest is to expose vulnerabilities in your organization's network before cybercriminals do. Click through examples of common vulnerabilities uncovered during internal network pentests. We describe the risk level and impact, just as we do in our independent pentest report.
Misconfigurations
Misconfigured firewalls, unnecessary open ports or default management interfaces reachable from the internal network give an attacker who is already inside direct extra footholds.

[ 04 ]Pentest methods
Pentesting methods
Black, Grey or White box? Pick a method below and see instantly how much knowledge the ethical hacker gets up front, and therefore how realistic the attack is.
The hacker starts completely blind
Black box Pentest
In a black box penetration test the organization gives the ethical hacker no information about the systems and IT structure up front. The ethical hacker only receives a scope consisting of a URL and/or IP addresses.
What the hacker sees up front

“I've capped off 5+ years of experience as an ethical hacker with an OSCP, OSED, OSWE, OSEP & OSCE3 certification. With that knowledge, I make sure your networks, websites, and mobile applications are tested thoroughly.”
