In the UK, a web application penetration test from an independent consultancy typically ranges from around £3,000 to £10,000+ per application, usually billed as a day rate (commonly £700–£1,200 per day) over a 5–10 day engagement. Larger firms with sales overhead and certifications often sit at the higher end.
Vesperis Security works differently: fixed pricing from £1,000 per web application, with no day rates and no hidden fees. You see the price before you commit, and it doesn't change because a test took a day longer.

Volume discounts apply automatically — the more applications in the engagement, the lower the per-app price. You can build an exact quote with the calculator in a few seconds.
Why fixed pricing?
Day-rate pricing pushes the risk of a slow estimate onto you and makes budgeting hard. A fixed per-application price means you know the cost up front, it's easy to get sign-off internally, and there's no incentive for anyone to pad the hours. For most small-to-mid-size applications, it also works out cheaper than a traditional consultancy.
What affects the cost of a pen test?
- Number of applications — the main driver, and where volume discounts help.
- Size and complexity — a large app with many distinct modules, or separate admin and customer portals, may be scoped as more than one application. We always confirm this during scoping, before any charge.
- User roles — more privilege levels mean more access-control testing.
- Retesting — with us, one retest of your fixes is included free, so it isn't an extra line item.
What's included in the price
Every engagement includes manual, expert-led testing, an executive and technical report, risk-rated findings, remediation guidance, and a free retest of fixes. There are no separate charges for the report or the retest. See exactly what a web application penetration test covers.
Is there a discount available right now?
Yes — as we build out our client portfolio we're running a limited introductory launch offer of 50% off every quote, and it stacks on top of the volume discounts above. The price shown in the calculator already reflects it.
