Network Penetration Testing

We test what your network exposes to the internet, and how far an attacker could move once inside.

§ 01Overview

External testing assesses your perimeter from an outside attacker's view. Internal testing assumes a foothold and establishes how far an attacker could move and escalate. Both end with reproducible findings, a documented attack path, and a retest.

§ 02What we test

The surface we cover

External perimeter

Internet-facing services, applications, and misconfigurations an outside attacker would target.

Internal movement

How far an attacker who already has a foothold can move across the network.

Privilege escalation

Paths from a low-privilege position toward domain or system control.

Segmentation

Whether network boundaries actually contain an attacker, or let them spread freely.

Exposed services and credentials

Weak, default, or exposed services and credentials that open the door.

§ 03How we approach it

A clear methodology, every time.

Scope and rules

Targets, exclusions, and rules of engagement agreed in writing up front.

Recon and access

We map the surface and attempt initial access using real attacker tooling and techniques.

Move and escalate

We move through the environment and escalate toward the agreed objective, reporting critical findings immediately.

Report and retest

A report with reproducible findings and a documented attack path, plus a retest of the fixes.

§ 04What you get

Results you can act on.

Every engagement ends with documented findings and evidence, written for the technical team and for the board.

FAQ

Questions, answered

What is the difference between external and internal testing?

External testing assesses your perimeter from the outside. Internal testing assumes an attacker already has a foothold and establishes how far they could move and escalate. Most organizations benefit from both.

Will testing disrupt the network?

We adapt scope to your risk tolerance and agree anything that could affect availability in advance. Sensitive environments are tested with extra care.

Do you retest the fixes?

Yes, a retest within 90 days is included.
