What we test

How far can an attacker get once they're inside?

Internal penetration testing starts from a position inside your network. The scenario is simple: assume someone has already gotten in. Maybe through a phishing email. Maybe through a compromised contractor account. Maybe through a vulnerability in an internet-facing system. Once inside, how far can they go?

We test what an attacker could access, escalate to, and exfiltrate from inside your environment. Active Directory environments, internal servers, workstations, shared file systems, and network segmentation are all in scope.

Testing can be conducted on-site at your location or remotely through VPN or jump-box access. We'll agree on the method during scoping.

Who it's for

Businesses that need to know their internal exposure

External testing tells you how someone gets in. Internal testing tells you what happens after they're already in. Both questions matter.

After a phishing incident
If someone clicked a malicious link or entered credentials on a fake page, your perimeter may already be compromised. Internal testing helps you understand what exposure that created and what was reachable.
PCI DSS compliance
PCI DSS requires annual internal penetration testing for any business that stores, processes, or transmits cardholder data. We format our report output to support your compliance documentation.
Assessing insider threat exposure
How much damage could a disgruntled employee or a compromised contractor account cause? Internal testing answers this with evidence, not assumptions.
Before the Bundle
If you're considering external and internal testing together, the Pentest Bundle covers both in one coordinated engagement and includes 8 hours of remediation support. Better value than booking separately.
