Web Application Penetration Testing

A web application penetration test goes beyond automated scanning to manually identify vulnerabilities in your web applications, portals, and APIs. Automated scanners catch the obvious issues. Manual testing finds the business logic flaws, authentication bypasses, and chained vulnerabilities that scanners miss entirely.

What Gets Tested

Authentication and session management, authorization controls, input validation (SQL injection, cross-site scripting, command injection), API security, file upload handling, business logic flaws, and data exposure. Testing follows the OWASP Testing Guide methodology and covers the OWASP Top 10 as a baseline.

How It Works

The tester works through your application as both an unauthenticated outsider and an authenticated user (if credentials are provided) to identify vulnerabilities at every access level. Each discovered issue is manually verified and exploited to confirm real-world impact. Testing is performed remotely against your production or staging environment, depending on your preference.

What You Receive

A detailed report with each vulnerability documented including the affected endpoint, request/response evidence, severity rating, and step-by-step remediation guidance your developers can act on directly. Findings are rated using CVSS scoring so your team can prioritize fixes by actual risk.

Who Needs This

Any business that operates a customer-facing web application, client portal, e-commerce platform, or API. If your application handles user data, processes payments, or controls access to sensitive information, it needs manual security testing beyond what a scanner provides.

How an engagement works

Scope

We define what's in bounds, your goals, and any operational constraints. For OT and production systems, safety and uptime come first.

Test

Hands-on testing the way a real attacker works. Findings are exploited and verified manually, proof of impact, not just a scanner flag.

Report

A prioritized report with clear remediation steps and proof of impact, written to be acted on, not a 200-page scanner dump.

Retest

Once your team has remediated, I re-verify the fixes so you can prove the issues are actually closed.

Frequently asked

How long does this take?

Most small-business engagements run one to two weeks from kickoff to final report, depending on scope and the number of targets. You'll get a clear timeline before any testing starts.

Will testing disrupt my operations?

Safety and uptime come first, especially for OT and production systems. We agree on rules of engagement up front, schedule intrusive testing around your operations, and I check in before doing anything risky.

Is the testing automated or manual?

A human drives every engagement and validates each finding by hand. Modern tooling (including AI) helps widen coverage and speed up the tedious parts, but you're paying for verified, exploitable findings, not raw scanner or model output.

Do you offer a retest after we remediate?

Yes. Once your team has fixed the findings, I re-verify the affected issues so you can demonstrate to customers, auditors, or leadership that they're actually closed.
