How Much Does an External Network Penetration Test Cost? (2026 Pricing by Scope)
An external network penetration test in 2026 typically costs between EUR 2,500 and EUR 10,000 (roughly USD 2,700 to USD 10,800), set by the number of live internet-facing IPs and exposed services, not the size of your company. At Budget Security the basis is a transparent day rate from EUR 849/day, so a small perimeter of a handful of public hosts runs 3 to 4 days and a large multi-IP footprint with many exposed services runs 8 to 12. You can scope your own in minutes below.
That range is narrower than an internal test for one reason: an external pentest is bounded by what an outside attacker can actually reach. It targets your internet-facing perimeter, the firewalls, VPN gateways, mail, DNS, and web services that face the public internet. Below are the variables that move the price, real 2026 ranges by perimeter size, and why an objective scope beats a sales-call estimate.

What Drives the Price of an External Network Pentest
Two things set the day count, and the day count sets the price. There is no fixed sticker because no two perimeters look the same.
Number of live IPs and exposed services
Your public IP footprint is the single biggest cost driver. A tester enumerates every live host, then probes every service each one exposes. Ten IPs that each run only HTTPS is a fast job. Three IPs that run mail, VPN, a web app, an admin panel, and a legacy FTP service is slower, because each exposed service is its own attack surface.
- A small perimeter of 1 to 5 live IPs with a handful of services is a 3 to 4 day job.
- A mid-size footprint of 5 to 20 IPs with mixed services runs 4 to 7 days.
- A large estate of 20+ IPs across several netblocks, or a heavy service mix, runs 8 to 12 days.
IP count is a proxy, not the whole story. A single IP fronting a complex web application can take longer than ten IPs that only answer on port 443.
Depth and goal: compliance readiness vs full exploitation
What you want out of the test changes the price as much as the perimeter size does.
- Compliance readiness (proving perimeter controls for ISO 27001, SOC 2, or NIS2) is goal-bounded. The tester confirms the exposed surface is hardened, documents the evidence an auditor needs, and stops there. Fewer days.
- Full exploitation (break through the perimeter, prove an outside attacker can gain a foothold, then show what that foothold reaches) is open-ended by design. You pay for the tester to push as far as a real attacker would. More days.
Picking the wrong goal wastes budget. A company that needs SOC 2 evidence does not need a full breach simulation, and a company worried about a public-facing breach is not served by a checkbox scan.
The external scope stops at the perimeter. The moment you want to test what happens after a breach, lateral movement, Active Directory, privilege escalation, that is an internal network pentest, which is priced and scoped separately.
2026 External Network Pentest Price Ranges by Perimeter Size
Use this as a sizing guide, not a quote. The ranges assume a remote test with a compliance-plus-exploitation scope, billed on a transparent day rate from EUR 849/day.
| Perimeter size | Typical scope | Days | Price (EUR) | Price (USD approx.) |
|---|---|---|---|---|
| Small (1 to 5 live IPs, few services) | Firewall, web, mail, readiness focus | 3 to 4 | EUR 2,500 to 3,400 | USD 2,700 to 3,700 |
| Mid-size (5 to 20 IPs, mixed services) | VPN, web apps, mail, DNS, some exploitation | 4 to 7 | EUR 3,400 to 6,000 | USD 3,700 to 6,500 |
| Larger (20 to 50 IPs, multiple netblocks) | Several netblocks, heavy service mix | 7 to 10 | EUR 6,000 to 8,500 | USD 6,500 to 9,200 |
| Large estate (50+ IPs, broad exposure) | Wide public footprint, deep exploitation | 10 to 12 | EUR 8,500 to 10,000+ | USD 9,200 to 10,800+ |
USD figures are approximate conversions for buyers sizing a budget in dollars and will move with the exchange rate. The day rate, not the table, is the source of truth.
For a typical SMB with a single office and a modest public footprint (a website, mail, and a VPN gateway), expect the small-to-mid band: 3 to 5 days, around EUR 2,500 to 4,800. A lean perimeter with one or two services lands at the lower end; multiple netblocks and a real break-in objective land higher.

Scope and price your testWhy AI Goal-Based Scoping Prices This More Accurately Than a Sales-Call Estimate
Here is the part the ranges above cannot tell you: where your perimeter actually falls inside them.
The traditional way to find out is a sales call. A senior pentester listens to your description, makes a subjective judgment, and quotes days. That judgment carries a built-in safety margin, because the estimator is guessing and would rather over-scope than run out of days mid-test. You pay for that margin.
Budget Security replaces the guess with an objective process. You register your internet-facing assets once, then pick the asset plus the goal (external network test, ISO 27001 readiness, NIS2, full exploitation) and a budget. The scoping AI proposes a test plan: how many days, what depth per service, exactly what gets tested.
Then it shows you the tradeoff live. Add a day and you see which service gets deeper coverage. Remove a day and you see precisely what gets cut, and whether the scope still meets your stated compliance goal. If a scope no longer guarantees the SOC 2 evidence you need, it tells you why. No estimation drift, no padded margin, no "contact sales" black box.
The test itself is run by OSCP-certified people, around 30 of them, with years of working history together. We kept the caliber of a premium consultancy and replaced the delivery model. Results come through a dashboard with an issue tracker, re-tests, and full engagement history, not an encrypted PDF that gets buried in a folder.
Transparent pricing is the consequence of that process, not a discount. Objective scoping removes over-scope waste, the platform removes project-management overhead, and self-serve removes the sales cycle. The fair price falls out of removing those costs. This is also why a scope-specific number beats a generic figure: if you want the wider context, the full pentest cost guide covers every test type, but your real number comes from scoping your actual perimeter.
External vs Internal Network Pentest: What Changes the Price
People often price these together, but they answer different questions, and the difference drives the cost.
- An external network pentest attacks your internet-facing perimeter from the outside: the firewalls, VPN, mail, DNS, and web services a remote attacker can reach with no prior access. Scope is bounded by your public IP footprint, so it is usually smaller and cheaper.
- An internal network pentest assumes the attacker is already inside (a phished employee, a rogue device, a stolen laptop) and measures how far they get across Active Directory, lateral movement, and privilege escalation. That is a larger surface, so it tends to run more days and cost more.
Most SMBs preparing for NIS2, SOC 2, or ISO 27001 need both, scoped together: the external test proves the perimeter holds, the internal test proves a breach would not become a catastrophe. You can size each one separately in the calculator, or scope them as a pair. For the internal side, see the companion guide on internal network pentest cost.
