Cost guide
Web Application Penetration Testing Cost
Web application penetration testing at Invadel starts at $5,200 for a small application, fixed in writing before any work begins. That price buys senior, manual testing against the OWASP Top 10 and your own business logic, an executive summary and full technical report, and a free retest of every fix.
Small
A single application with one or two user roles, a contained feature set, and standard authentication, such as a marketing site with a login or an early-stage product.
Medium
An established product with several user roles and an admin panel, third-party integrations, and more workflows to abuse, or two smaller applications tested together.
Large
A large or multi-tenant platform with many roles, complex business logic, extensive APIs, and several integrated components tested together as one system.
What moves the number
What drives the cost of web application penetration testing
Number of user roles and tenants
Every role and tenant multiplies the access-control testing, because we check what each one can reach and whether any can cross into another. More roles means more authorization paths to exercise by hand.
Size of the application
A larger feature set means more forms, workflows, and states to test. Counting the distinct screens and user journeys during scoping is how we size the effort rather than guessing from a homepage.
Business logic complexity
Payments, multi-step approvals, quotas, and pricing rules are where the serious findings live, and they take time to understand and abuse. The more custom logic your product runs on, the more testing it needs.
Authenticated versus anonymous
Testing behind the login, across every role, finds far more than an anonymous pass. Providing an account for each role is expected and keeps the price down; having us create them adds effort.
Modern front ends and integrations
JavaScript-heavy single-page apps, GraphQL back ends, and third-party integrations each add surface. They are tested at the same depth as server-rendered pages, which the scope has to account for.
Production versus staging
Testing against a dedicated staging environment is faster and safer. When production is the only option, agreeing rules of engagement and safe testing windows adds a little coordination to the scope.

Keep it tight
How to keep the price down
- 01Provide a working test account for every user role and tenant up front. Building them for us, or testing role by role without them, adds time we would rather spend finding flaws.
- 02Point us at a staging environment that mirrors production. It is safer to test hard, avoids production rules of engagement, and lets your team fix against the same build.
- 03Scope to the application that matters most this quarter rather than everything at once. A tightly defined target is cheaper now, and the rest can follow on its own timeline.
- 04Share your architecture, API docs, and any prior test or scanner output during scoping. The less time we spend mapping the application, the more of the fee goes into testing it.
Timeline
Onboarding begins within 24 hours of a signed proposal, and testing usually starts within a week of scoping. A small application runs about a week of testing followed by reporting. Medium and large applications, with more roles and workflows, take longer. We share any critical finding the moment we confirm it, and the free retest follows your fixes.
FAQ
Questions about web application penetration testing cost
01How much does a web application penetration test cost?
It starts at $5,200 for a small application, fixed in writing before work begins, with no hourly billing and a free retest of remediated findings included. Medium applications start at $7,800 and large or multi-tenant platforms at $12,500 and up. Your exact figure is confirmed in writing from your scope details, no sales call required. See the pricing page for every service.
02What makes one web application test cost more than another?
Mainly the number of user roles, the size of the feature set, and how much custom business logic the application runs on. Authenticated testing across every role finds the most, so more roles and more workflows mean more to test. A large multi-tenant platform with heavy APIs sits at the top of the range.
03Is the retest really free?
Yes. After your team fixes the findings we retest them at no extra cost and update the report to show them closed, which is the evidence an auditor or customer actually wants. It is part of the fixed price, not billed as a second engagement.
04Can we lower the price by testing only part of the application?
Yes. Scoping to the application, or the features, that matter most this quarter is a legitimate way to keep the number down, and the rest can follow later. We help you draw a sensible boundary during scoping rather than testing everything at once.
05Does the price change if you find something serious mid-test?
No. The price is fixed before work starts and does not move because testing surfaced more than expected. We share critical findings the moment we confirm them so you can begin fixing, and the number on your proposal is the number you pay.
