What we look for

Internal network vulnerabilities we hunt for

Most breaches do not stop at the perimeter, they spread. We test how far a single foothold can reach through your network, your segmentation, and your Active Directory.

Active Directory Attacks

Abuse of Active Directory to escalate from a standard user to domain admin.

We test for

  • Kerberoasting and AS-REP roasting
  • ACL and delegation abuse
  • Weak GPOs and privileges
  • Domain privilege escalation

Lateral Movement

Techniques that spread a single foothold across the whole network.

We test for

  • Credential harvesting and reuse
  • Pass-the-hash and pass-the-ticket
  • SMB and remote execution
  • Trust and share abuse

Segmentation & Access Control

Flat networks that let one compromised host reach everything.

We test for

  • VLAN and segmentation testing
  • Reachability of sensitive zones
  • Firewall and ACL gaps
  • Exposed internal services

Credential & Service Weaknesses

Weak secrets and insecure services waiting on the internal network.

We test for

  • Default and weak credentials
  • Cleartext protocols and secrets
  • LLMNR and NBT-NS poisoning
  • Service misconfiguration

FAQ

Frequently asked questions

What teams most often ask before scoping internal network penetration testing.

Still have questions?
01What does an internal network penetration test simulate?

It simulates an attacker who already has a foothold inside your network, whether from a phishing email, a rogue device, or a compromised host, and tests how far they can move, whether segmentation holds, and whether Active Directory can be abused.

02Do you test Active Directory?

Yes. Active Directory is central to most internal networks and a primary target, so we test for the common escalation and lateral-movement techniques attackers use to reach domain admin.

03How is testing performed?

We test from a device or foothold inside your network, either on-site or through a provided appliance or virtual machine. We agree the exact approach during scoping.
