Network Security Testing

External perimeter assessment, internal lateral movement, segmentation validation, and Active Directory abuse paths, the same tradecraft real intruders use.

What it is

We assess your network from the outside in and the inside out. External perimeter, internal lateral movement, segmentation validation, and the Active Directory attack paths that turn one foothold into domain dominance.

Kerberos abuse, NTLM relays, GPO escalation, BloodHound graphs. We use the real tradecraft, then hand you the map and the fixes.

An optional assumed-breach scenario starts us with workstation-level access, modelling exactly what a phished employee gets an attacker to.

FAQ

Questions security leads actually ask.

What does network security testing cover?

External perimeter assessment, internal lateral movement, segmentation validation, and the Active Directory attack paths (Kerberos abuse, NTLM relays, GPO escalation) that turn one foothold into domain dominance.

What is the assumed-breach option?

An optional scenario that starts the test with workstation-level access, modelling exactly what a phished employee hands an attacker.

How long does a network test take?

One to four weeks, depending on scope and the vectors in play.

What do we receive?

External and internal findings reports, an Active Directory attack-path graph (BloodHound export), a segmentation matrix of what reached what, a prioritized hardening playbook, and an executive risk summary.

Do you retest fixes?

Yes. The engagement includes verification of remediations after hardening.
