Web application penetration testing companies compared

This page is for buyers who need a pentest of one or more web applications and want a shortlist. The table filters the PentestCompare dataset to providers whose pages state web app testing. It runs A to Z, no provider pays for position, and each fact links to the provider's own page with the date we checked it.

What does a web application penetration test cover?#

A web application penetration test is an authorized attempt to break a web app and prove what an attacker could do. The tester works from the outside, or signed in as a normal user, and tries to reach data or actions the account should not reach.

The standard reference for the work is the OWASP Web Security Testing Guide. Its stable release is v4.2 (the "latest" branch is development work toward 5.0). Providers also name the OWASP ASVS, a list of security requirements for web apps, as a coverage target. ASVS 5.0.0 was published on 30 May 2025.

Four areas make up most scopes:

• Authentication and session handling: login, password reset, tokens, multi-factor steps.
• Access control: whether user A can read or change user B's records, and whether a normal user can reach admin functions.
• Input handling: injection, cross-site scripting, file upload, server-side request forgery.
• Business logic: flows that follow the rules of the code but break the rules of the business, such as applying a coupon twice.

Ask the provider to confirm which areas are in the quote. A scanner-only product usually covers input handling. Access control and business logic need a person or an agent that holds several accounts.

Who needs a web application pentest, and when?#

You need one when customers, auditors or your own risk review ask for evidence that someone tried to break your app. Common triggers are a first enterprise sale, a security questionnaire, a major release that changes login or billing, and a compliance cycle.

Compliance frameworks do not all require a pentest. For example, SOC 2 names penetration testing only as one example of an evaluation. See our guide to SOC 2 penetration testing providers before you buy for an audit, and ask your auditor what they accept.

Test when the app is stable enough to hold real flows. A test of a half-built app finds issues that the next release removes.

What should you ask web app pentest providers?#

Ask for written answers to these six questions before you compare quotes. The full question list has more.

1. Which roles and test accounts will the tester use, and who creates them?
2. Is the API behind the front end in scope, and are API endpoints that the front end never calls in scope?
3. Does the report include requests and responses for each finding, so your developers can reproduce it?
4. What does the quote say about retesting: how many rounds, and for how long?
5. Can we see a sample report before we sign?
6. Which testing runs on your production system, and which limits apply (rate, uploads, email sending)?

The table has a column for the sample report and one for the provider's retest statement. Many providers answer "Not published" for turnaround. That is a fact about their pages and not a judgment of the work.

What drives the price of a web application pentest?#

Scope drives price more than any other factor. The provider's own price pages name these drivers:

Published prices in the dataset show the range. As of 9 November 2026, Intruder listed its single pentest at $3,500 per test (Intruder). Stingrai listed an autonomous pentest at US$3,000 per assessment (Stingrai). CYBRI listed a web application test starting at $5,000 per engagement (CYBRI). Secure Ideas listed its smallest web application test at $13,600 starting flat fee (Secure Ideas). These are start prices for the smallest scope each provider lists, so they are not comparable quotes. Most providers quote on request; the cost guide lists more providers' prices.

How do you read the table?#

Read the table as a screening step, not a ranking. Rows are sorted A to Z. A row shows what the provider states on its own pages, and "Not published" means we found no statement.

Use the Delivery filter above the table to split the field. Manual depth, compliance packaging and continuous or automated testing are different products that all use the words "web application penetration testing". Pick the delivery model first, then compare price, retest terms and sample reports inside that group.

Check the sample report column before anything else. A public sample report lets you judge the evidence standard without a sales call. Our guide to judging a provider by its sample report lists what to look for.

Which scoping mistakes cost the most?#

Four mistakes appear in most quotes that later change.

• Scope names the domain but not the roles. The tester then has one account and cannot test access control between users.
• The API is left out. Modern web apps put most logic in the API, so a front end only test misses it.
• Third-party systems sit in scope without permission. Payment, email and identity providers have their own testing rules. Get written permission or exclude them.
• The test runs against production with no limits. Agree limits on uploads, password guessing and email sending first.

Use the scoping checklist to build a scope like this one. It covers roles, API size, environments and limits.
