Network penetration testing. Internal and external, started today

Test your network the way an attacker actually moves through it.

A real intrusion doesn't stop at the perimeter — it moves laterally once it's in. We test both your external attack surface and your internal network, tracing how an attacker who gets a foothold could move, escalate, and reach what matters. Start online, no scoping call.

Why teams test the whole network

Perimeter testing alone doesn't answer "what happens after a breach starts."

External testing tells you what's reachable from the internet. Internal testing tells you what happens next — how far an attacker who gets a foothold (phishing, a compromised laptop, a rogue device) could move before anyone noticed. Full network penetration testing covers both: the perimeter and what's behind it.

What audit-grade means

Five commitments that separate a real pentest from a quick-find scan.

"Audit-grade" is a category, not a slogan. It means the report holds up to your auditor's review, your prospect's security team, and your insurance underwriter — not because we say so, but because of what we commit to do on every engagement.

Internal + external scope

One engagement covers both your perimeter and your internal network segments.

Lateral movement testing

We test how far a foothold could spread — privilege escalation, lateral movement, and access to sensitive systems.

Retest from scratch

When you remediate, we retest everything from scratch, not just the listed findings. New issues that surfaced since the original test get reported too.

Honest pricing

Published list pricing by the number of assets you want tested. No quote, no negotiation, no sales-rep discount theater.

Self-serve, no calls

Answer a few quick questions, purchase, and receive your report. Standard scope needs no scoping call.

Coverage, not quick wins

Bug-bounty and PtaaS testing chases quick wins.
A real network pentest is graded on coverage, not the first finding.

The cheap pentest options inside compliance platform marketplaces optimize for time-to-first-finding. They're excellent at surfacing the obvious. They're not designed to trace how far a foothold could actually spread.

Quick-find testing

Bug-bounty and PtaaS researchers race for the first finding. Coverage of the rest of your network, internal or external, isn't the goal of the system.

Scanner-only testing

Automated tools find what they recognize. Lateral movement, privilege escalation, and access to sensitive systems aren't things a scanner can trace.

Audit-grade testing

Every service on every in-scope asset, perimeter and internal alike. If you list it, we test it.

Honest pricing

Published rates. No quotes. No sales calls.

Network scope ranges from a single office to multi-site environments with internal segmentation. Pricing scales with the number of hosts, IPs, or cloud endpoints you want tested.

How pricing works: The first asset covers the essential work every engagement requires — scoping, setup, validation, and reporting. Pricing scales with your environment from there. Count each public-facing host, IP, or cloud endpoint you want tested — they don't have to be contiguous or in the same network. If you have more than 256 assets, contact us.

Network Pentest FAQ

What teams ask before they buy a network test.

What's the difference between this and the External page?
External testing covers only what's reachable from the internet. This engagement adds internal network testing — what an attacker could do after getting a foothold inside your network. Choose this page if you want both.
How do you test internal segments — remotely or on-site?
Typically via a testing appliance or VPN access you provide into the internal segment; on-site testing can be arranged if needed. Tell us your environment when you order.
How long does it take?
There's no sales queue to wait on — scoping starts as soon as you check out. Duration scales with the number of assets and network segments in scope; we'll confirm your specific timeline before testing begins.
Is there a sales call?
No for standard scope — choose from the pricing table and checkout online. Email hello@pentestexpress.com if your internal segmentation needs discussion first.
What if I need a retest after remediation?
We retest everything from scratch, not just the listed findings. Free retest within 14 days of report delivery. From day 15 through day 60, retest is 25% of the original price. After 60 days, a full re-engagement is recommended because the environment has typically drifted.
Can our procurement team approve this without a custom SOW?
Yes for standard scope. Pricing is fixed and published. The standard authorization and rules-of-engagement are in our Terms of Service — most procurement teams clear it in days, not weeks. If your process specifically requires a Statement of Work, select that option at signup and we'll send it for signature through DocuSign instead of running payment through Stripe.
