Web application pentest
Web application pentesting focused on business risk
We test user journeys, server-side logic, and trust boundaries the way a motivated attacker would use them.
Manual business-logic testing extends OWASP WSTG and ASVS coverage across authentication, authorization, and chained weaknesses.
01 / Coverage
What we test
We confirm boundaries and critical journeys before testing so the work reflects your business risk.
Identity and sessions
Registration, sign-in, recovery, MFA, session handling, and role bypasses.
Business logic
Abuse of payments, limits, order states, and multi-step workflows.
Input and server side
Injection, SSRF, file upload, deserialization, and unsafe data processing.
Browser and integrations
XSS, CSRF, CORS, WebSockets, third-party components, and client-side secrets.
02 / Method
An assessment you can defend to engineers and auditors
We combine manual investigation, tooling, and evidence control. A specialist validates every reported finding.
- 01
Model the threats
Confirm architecture, roles, valuable data, and the journeys with the highest plausible impact.
- 02
Investigate manually
Explore application behavior and use tools where they improve depth and coverage.
- 03
Prove the impact
Reproduce safely, preserve useful evidence, and remove false positives from the report.
- 04
Support the fix
Walk through findings, prioritize remediation, and retest the implemented controls.
03 / Outputs
Material built for decisions and remediation
The report explains risk to leaders and gives engineers reproducible steps without scanner noise.
PENTEST.RED / WEB / 01
Engineering report
Reproduction steps, evidence, impact, affected components, and practical remediation guidance.
Executive brief
Material attack scenarios, priorities, and a concise view of the system’s exposure.
Readout session
A live walkthrough for engineering, product, and security stakeholders.
Retest
Validation of fixes and likely bypasses within the agreed retest window.
How long does a web application pentest take?
Most engagements take one to three weeks. Timing depends on roles, features, integrations, and depth; we confirm the calendar after a short scoping call.
Do you need source code?
No. Black-box and grey-box testing fit most goals. Source access can be added for deeper review of critical components.
Can you test production?
Yes, when the risk is acceptable and the rules of engagement allow it. We agree testing windows, rate limits, prohibited actions, and emergency contacts first.
Do you retest fixes?
Yes. The retest confirms the original path is closed and checks for obvious bypasses.
