Web Application Penetration Testing
Break your web app before attackers do
Certified testers exploit every flaw in your web application by hand, from broken access control to injection, and hand you a working proof-of-concept for each one.
Automated scanners flag a login form and move on. We log in as another user, pull their records, and show you exactly how it happened. SiegePoint's web application penetration test is a hands-on, exploit-driven review of your app's authentication, authorization, and business logic, run by testers who hold OSCP and OSWE and mapped to the SOC 2, ISO 27001, PCI DSS, or HIPAA control each finding touches.
What we test
Where we focus.
Broken access control (IDOR / BOLA)
Reaching another tenant's data by changing an ID, forging a role, or skipping a check.
Authentication and session flaws
Credential stuffing, weak or bypassable MFA, fixed session tokens, and JWT tampering.
Injection (SQLi, XSS, SSTI)
SQL, cross-site scripting, and template injection that reach your data or run code.
Server-side request forgery (SSRF)
Forcing your server to hit internal services, cloud metadata, or credential endpoints.
Business logic abuse
Price tampering, coupon stacking, replay, and workflow steps run out of order.
Insecure deserialization and file handling
Object injection, unsafe uploads, and path traversal that lead to remote code execution.
Data exposure and misconfiguration
Secrets in responses, verbose errors, missing security headers, and permissive CORS.
API and GraphQL abuse behind the app
Mass assignment, over-permissive queries, and hidden endpoints your UI never shows.
How it works
From scope to retest.
Scope
A short call to map your app: user roles, tenancy model, key workflows, and the endpoints that matter. You get a fixed price and a fixed timeline before any testing starts.
Test
Certified testers work by hand across authenticated and unauthenticated roles, chaining issues and exploiting each one with a working proof-of-concept, never a raw scanner dump.
Report
You get a ranked report: severity by real business impact, reproduction steps, evidence, remediation guidance, and every finding mapped to its SOC 2, ISO 27001, PCI DSS, or HIPAA control.
Retest
Once your team ships fixes, we retest every finding to confirm it actually holds. The retest is free and included in the engagement.
What you get
In your report.
- ✓A working proof-of-concept for every confirmed finding, signed off by a certified tester
- ✓Severity ranked by real business impact, not just a raw CVSS number
- ✓Step-by-step reproduction and clear remediation guidance for each issue
- ✓Every finding mapped to the SOC 2, ISO 27001, PCI DSS, or HIPAA control it affects
- ✓A free retest after fixes, plus a clean attestation letter for auditors and customers
Questions
Answers, up front.
Do you actually exploit findings or just scan?
We exploit. Every issue in the report is proven with a working proof-of-concept and reviewed by a certified tester, so your engineers never waste time chasing a false positive.
Will this satisfy our SOC 2 or PCI requirement?
Yes. The test meets the annual penetration testing requirement, and each finding maps to the specific control it affects with the evidence an auditor expects to see.
How long does a web app test take?
Most engagements run one to two weeks depending on app size and the number of roles. We scope it on a short call and commit to a fixed price and timeline up front.
