Overview
From fintech lenders and patient portals to e-commerce checkouts and B2B SaaS, US web applications are judged on access control and data protection. We test every role and workflow by hand, map findings to the OWASP Top 10, PCI DSS and SOC 2 criteria, and explain the business impact in plain English for engineering and leadership.
Web applications are where your customers, your data and your revenue meet — and they are the most common entry point in real-world breaches. Our web application penetration tests go well beyond the OWASP Top 10 checklist to find the issues that actually lead to data exposure.
We test as every user role you have, and for SaaS platforms we test across tenants: can one customer read, modify or delete another customer's data? Can a standard user reach admin functions? Can a checkout, approval or refund workflow be manipulated? These questions require human understanding of how your application is supposed to work.
Testing follows the OWASP Web Security Testing Guide (WSTG), with findings mapped to the OWASP Top 10:2025 so they are easy to communicate to stakeholders and auditors.
How testing works for US organizations
- Signed scope and written authorization before any testing, including hosting and cloud provider permissions
- Testing windows agreed around your US time zone at scoping, including after-hours windows for production
- Fully remote delivery, with internal and wireless access via VPN or a shipped test device, so no travel costs
- Reports mapped to SOC 2, PCI DSS, HIPAA and customer questionnaires, with a fixed price in USD
What's included
Our approach
- Application walkthroughWe learn your roles, data model and critical workflows — ideally with a short call with a product owner.
- Mapping & discoveryWe crawl and proxy the application, identify hidden endpoints and enumerate parameters.
- Authenticated manual testingEach role is tested against every function and object, alongside targeted tooling.
- Exploit chainingLower-severity issues are combined to demonstrate realiztic attack paths.
- Report, debrief & retestClear evidence and fixes for developers, followed by verification of remediation.

Frequently asked questions
Gray-box or black-box — which is better?
Gray-box (with test accounts and some documentation) gives the deepest coverage for the budget and is what we recommend for most applications. Black-box is useful for simulating an external attacker against public functionality.
How do you price a web application test?
Effort is driven by the number of user roles, dynamic pages, API endpoints and complex workflows. We provide a fixed price after a short scoping call.
Can you test applications behind a WAF?
Yes. We can test with the WAF in place, allow-list our IPs for depth, or do both to evaluate the WAF's effectiveness.
Are you a PCI QSA or ASV, FedRAMP 3PAO or CMMC C3PAO?
No. We don't claim any of those statuses on this site. Most penetration tests for SOC 2, HIPAA, PCI DSS Requirement 11.4, the FTC Safeguards Rule and customer due diligence don't require them. If your contract, assessor or program requires a specific accredited provider, tell us at scoping and we'll say plainly whether we can meet it. See US compliance requirements.
Do you quote in US dollars?
Yes. US proposals are fixed-price and quoted in USD, with scope, effort, deliverables and payment terms set out in writing before work starts. See our US pricing guide for published market ranges.
