Cyber Security Services- Securing Fortune 100 companies since 2014
Our web application penetration testing finds the flaws attackers use to reach your data: broken access control, injection, authentication weaknesses and business logic errors that automated scanners cannot see. Testing is manual and follows the OWASP Web Security Testing Guide, with every finding proven, rated and explained so your developers can fix it. It is one part of our penetration testing services.
Customer portals, SaaS platforms, e-commerce sites and internal business applications, tested against the OWASP Top 10 and beyond.
REST and GraphQL APIs behind your web and mobile applications, tested against the OWASP API Security Top 10.
Login, single sign-on, multi-factor authentication, password reset and session handling, where small mistakes often lead to full account takeover.
We study how your application is meant to work and then try to misuse it: skipping steps in a workflow, manipulating prices or quantities, abusing roles and approvals, and accessing other customers’ data.
We agree on the applications, environments, user roles and test accounts in scope, and whether testing runs against production or a staging copy, documented in a Statement of Work and authorization letter.
We map every page, endpoint, role and data flow, review API documentation where available, and identify the functions an attacker would target first.
Testers work through the OWASP Web Security Testing Guide by hand, supported by tools, and exploit what they find to show real impact, such as reading another customer's records.
You receive an executive summary and a developer-friendly technical report with reproduction steps, request and response evidence, severity ratings and specific fixes for each finding.
Our testers answer your developers' questions during remediation and retest fixed findings, giving you a clean retest letter for customers and auditors.
Schedule a scoping call with our penetration testing team. We will define the right engagement for your environment, compliance requirements, and budget, and deliver findings that drive real security improvement.

Scanners find known patterns such as missing headers and outdated libraries. They cannot tell whether one customer can read another customer's data or whether a workflow can be abused. Those access control and business logic flaws are where most serious web application findings come from, and finding them takes a person.
Either. Staging is safer for destructive tests and is preferred when it closely matches production. Production testing is common for read-only and access control testing and is planned to avoid disruption.
Yes. Mobile and single-page applications are only as secure as the APIs behind them, and we test those APIs directly against the OWASP API Security Top 10.
Yes. SaaS companies use our web application penetration test reports and retest letters as evidence for SOC 2 audits, ISO 27001 and enterprise customer security questionnaires.
A small web application typically costs $4,000 to $8,000 to test. A larger web application with APIs typically falls in the $10,000 to $30,000 range. We provide a fixed quote after a free scoping call.
Most applications take one to three weeks of testing, depending on the number of pages, roles and API endpoints.
