Internal penetration testing Know what happens after an attacker gets in.

Most serious breaches start with one foothold inside the network. Internal penetration testing shows how far an attacker could go from there, before a real one finds out for you.

What you getKnow how far one compromised account or device could spread, and which internal weaknesses to fix first.

What it is

We simulate an attacker with network access or insider knowledge. We look for privilege escalation paths, lateral movement routes, password weaknesses, Active Directory flaws and detection blind spots, then chain them together the way a real adversary would to reach what matters most to your business.

What your team gets

The attack paths from a single foothold to your most valuable systems and data
Weak passwords, risky permissions and Active Directory flaws, ranked by real risk
Where your monitoring did and did not notice us

How it works

Scope it together

We agree on what is in bounds, what matters most to your business and how we stay safe while testing.
We attack, carefully

Our ethical hackers work like a real adversary inside the agreed limits. If we find something serious, we call you right away instead of waiting for the report.
Walk through the results

You get findings in plain language, ranked by business risk, with clear fixes your team can carry out.
Confirm the fixes

We retest what you fixed, so you know the problem is truly solved.

Year-round partnership

Make it part of year-round support.

Internal penetration testing is available as part of HackerGuards, our year-round support. Instead of one test a year, our ethical hackers keep testing as your environment changes, so new weaknesses close before an attacker finds them.
