Testing Services

A vulnerability scan uses automated tooling to flag known weaknesses in a web application. A penetration test goes further, showing how well your existing defenses hold up against a real-world attacker who chains those weaknesses together, abuses business logic, and works toward your data the way a cybercriminal actually would.

Web application security testing is the umbrella term for any evaluation of how secure a web app is, from automated scans to code review. A web application penetration test is the deepest form of it: senior testers manually attack the application the way a real adversary would and validate which weaknesses are genuinely exploitable. When a client, auditor, or framework asks for web application security testing, a manual penetration test is the strongest evidence you can provide. Buyers often call the same engagement website penetration testing, which usually means this test scoped to a public-facing site.

Initial testing for most engagements takes approximately one week. Once we confirm any critical findings, we share them right away alongside an executive presentation of the results and clear remediation guidance. After your team applies the fixes, we run a full retest at no additional cost.

Our dedicated security specialists tailor the breadth and depth of testing to your application's architecture and its cloud deployment and service model. We combine automated dynamic analysis with heavy manual testing of the user-facing interface, validating it against the OWASP Top Ten and the wider OWASP Testing Guide to confirm real, exploitable impact rather than theoretical risk.

Any organization that relies on a web application to run its business or handle sensitive data. It is an essential tool for confirming that your security controls actually work, and for meeting compliance mandates that apply to your application. Most organizations benefit from testing annually, or twice a year for higher-risk or frequently updated applications.

Our web application penetration tests start at $5,200 for a small application, with the price fixed before work begins, no hourly billing, and a free retest of remediated findings is included. Medium applications start at $7,800 and large or multi-tenant platforms at $12,500 and up, with your exact figure confirmed in writing from your scope details, no sales call required. You can see starting prices for every service on our pricing page.

Yes. Most serious findings live behind the login. We test every role and tenant you provision, from anonymous visitor through end user to administrator, and look specifically for horizontal and vertical access-control failures between them. Provide a test account for each role during scoping and we exercise all of them.

Gray box is the default for most web application tests: we get credentials and documentation, which lets us spend the engagement on depth instead of guesswork. Black box models an outside attacker with nothing, useful for a first look at a public application. White box adds source code and is the most thorough option when you pair the test with a secure code review. Our guide to black, gray, and white box testing covers the trade-offs.

We test against staging or a dedicated test environment whenever one exists. When production is the only option, we agree rules of engagement in advance: no denial-of-service techniques, no destructive payloads, defined testing windows, and immediate escalation of anything critical. Fixed scope means you know exactly what is being tested and when.
