Infrastructure Security Testing

Network & Infrastructure Penetration Testing

Internal and external network penetration testing to find lateral movement paths before attackers do.

Once an attacker has a foothold — a phished credential, a compromised laptop — infrastructure weaknesses determine how far they can move. We simulate this: testing your internal and external network perimeter, Active Directory configuration, and segmentation controls to map exactly how far a compromised account or device could reach, and close those paths before a real incident does.

Who Needs This

Enterprises with internal networks, Active Directory environments, and any organization that has never validated how far a single compromised endpoint could reach.

What's Included

External perimeter testing — exposed services, firewall policy validation, port scanning

Internal network penetration testing and lateral movement simulation

Active Directory security review — privilege escalation, Kerberoasting, misconfigurations

Network segmentation validation between critical zones

Firewall and VPN configuration review

Full attack-path report showing how far a single compromise could spread

Frequently Asked Questions

What's the difference between internal and external network testing?

External testing simulates an attacker with no prior access probing your internet-facing perimeter. Internal testing simulates an attacker who already has a foothold — a phished laptop or compromised VPN account — and measures how far they can move inside your network.

Will this testing disrupt our production network?

We agree on testing windows and rules of engagement upfront specifically to avoid disruption, and exploitation is performed safely with rollback plans for any higher-risk techniques.

Do you test our Active Directory environment specifically?

Yes — AD misconfigurations are one of the most common lateral-movement and privilege-escalation paths we find, so it's a core part of internal infrastructure testing.
