Internal Network Penetration Testing

Assumed-breach testing of lateral movement and privilege escalation inside the perimeter.

Overview

Internal network penetration testing is assumed-breach testing from inside your perimeter — modeling how an attacker with an initial foothold moves laterally, escalates privilege, and reaches sensitive data.

What we test

Where attackers get in — and where we look.

Lateral movement paths

Privilege escalation

Segmentation gaps

Credential harvesting

Sensitive data access

How we test

A proof-driven methodology.

Scope & recon

We agree objectives and rules of engagement, then map what you actually expose.

Map the attack surface

Enumerate entry points, roles, and trust boundaries a real attacker would target.

Manual exploitation

Certified testers exploit flaws by hand — chaining issues scanners never connect.

Prove impact

Every finding ships with a working, reproducible proof-of-exploit and business context.

Report & retest

Risk-ranked report with fixes, then a retest that confirms each issue is closed.

What you get

Proof you can act on.

Reproducible proof-of-exploit

Every finding ships with a working exploit and evidence.

Risk-ranked report

CVSS + business context, prioritized for your team.

Remediation guidance

Actionable fixes mapped to each finding.

Retest to verified fix

We confirm closure — proof it’s fixed, not assumed.

Related programs

Make it continuous.

Pair this test with a program that keeps coverage live between engagements.

FAQ

Internal Network Penetration Testing — questions buyers ask.

What does “assumed breach” mean?

We start with the access a real attacker would have after phishing one employee, then show how far that access can be pushed — lateral movement, privilege escalation, and data access.

Do you need to be on-site?

No — we can test remotely via a provided device or connection, or on-site if preferred.

Is Active Directory included?

AD is often the fastest path to domain compromise; we can include it here or scope dedicated Active Directory testing.

Prove what an attacker could actually do.

A short scoping call, no obligation.
