Application Penetration Testing

Manual testing for web apps, stores, and customer portals. We test how your business logic can be abused, not just scanner output. Retest included.

The vulnerability that costs you money is almost never a CVE.

It's the discount code that stacks with itself. The checkout that trusts a price submitted by the browser. The order ID in a URL that returns someone else's order when you increment it. The password reset that works without the token. The endpoint that checks whether you're logged in but never checks whether the record belongs to you.

Automated scanners can't find these. There's no signature for "this application's rules can be bent." Finding them requires someone who understands what your application is for.

What We Test

Web applications, e-commerce stores, SaaS platforms, customer and patient portals, internal tools, and the backends behind mobile apps.

Authentication and sessions. Login flows, password reset, multi-factor implementation, session lifetime, token handling, and account takeover paths.

Authorization. Whether a standard user can reach admin functions. Whether one customer can reach another customer's data. Tested from every role, not assumed from the code.

Business logic abuse. Pricing, discounts, quantities, refunds, workflow sequencing, race conditions in checkout and booking. The tests specific to your application that nobody else will run.

Injection and input handling. SQL injection, cross-site scripting, template injection, file upload handling, deserialization.

Configuration and exposure. Security headers, error messages leaking internals, debug endpoints left enabled, verbose responses.

The OWASP baseline. Top 10 and ASVS-aligned coverage, so the standard ground is documented for your auditors and customers. Then we spend the remaining time on what's specific to you.

How It Works

Scoping. We agree exactly what's in scope, which environment, what credentials and roles we need, and what happens if we find something critical mid-test. That last one matters — you're told immediately, not in the report three weeks later.

Authorization. Nothing begins without signed written authorization. If you're on a hosted platform, we confirm the provider's testing policy first.

Testing. Manual, authenticated, across every user role. Automated tooling supports the work; it doesn't replace it.

Reporting. An executive summary for leadership, plus technical findings with reproduction steps, evidence, business impact and specific remediation guidance — written so a developer can fix the issue without booking a call. The call is included anyway.

Retest. Once you've remediated, we verify the fixes and reissue the report. Included in the engagement, not billed separately, because a finding you can't prove is closed isn't closed.

Questions We Get Asked

Production or staging?
Staging, where it genuinely mirrors production. Where it doesn't — and it usually doesn't — we test production carefully, in agreed windows with agreed constraints. We'll talk through the tradeoff honestly rather than defaulting to whichever is easier for us.

How long does it take?
Typically one to three weeks, depending on application size, number of user roles and complexity. Scoping tells us which.

We need a report for a customer's security review. Will this satisfy them?
Usually. Tell us at scoping who's asking and what they require, and we'll make sure the deliverable answers their questionnaire directly.

What if you don't find anything serious?
Then the report says so, and that's a legitimate result you can hand to a customer. We don't inflate findings to justify an invoice.
