Penetration Testing for web apps, mobile apps, APIs and cloud
We test your application like an attacker would. Agents we built run thousands of tests in parallel, our specialists verify every finding, trace the attack path and engineer the fix down to the code. Built for SaaS companies, startups and software vendors.
What we test
One engagement can cover every surface a company runs:
- Web applications and their backends.
- Mobile apps for Android and iOS.
- APIs, REST and GraphQL.
- Cloud environments on AWS and Azure.
- Infrastructure and the external attack surface.
How an engagement works
Agents run the broad part: thousands of parallel tests across code, configuration and network behavior. Human specialists take over where context matters. They confirm each finding with a proof of concept, follow how an attacker would move through the system and rank the consequences. We test only systems you own or may test.
What you receive
A written report with the evidence behind each finding, a CVSS severity, the attack path and fix guidance. From the Growth plan we engineer the fix itself down to the affected code and retest it. The report is technical evidence, not a certificate.
Evidence from audited software
The public ledger lists 387+ audited apps and 262+ critical findings. These full reports show how we document what we find:
- SAP: A Chinese push SDK in a field-service app, and Firebase keys hardcoded across five apps.
- Nike: Development and production push credentials hardcoded in the shipped build.
- Strava: A hardcoded key and a security configuration that protects nothing.
- Revolut: The largest third-party SDK in the series and what it sends to a US company.
Every other investigation is in the full evidence ledger.
Start with the Domain Security Test
The Domain Security Test examines one domain from the outside: read-only, from a European IP address, with no login and no payloads. A researcher reviews your request and replies within one business day.
Plans and prices are on the Access page, the agents behind every review on The Squad page.
Plans and prices are on Access, the agents behind every review on The Squad and the frameworks we measure against on Standards.
Put your domain to the test. Submit it for an initial external security assessment of your publicly accessible attack surface.
No login, no payloads and no changes to your systems.
A researcher reviews your request before testing begins and responds within one business day. You'll receive a short written report covering our findings, likely attack scenarios, potential financial impact and recommended next steps, alongside an exportable security intelligence graph connecting the findings.
Questions about penetration testing
How is this different from a vulnerability scan?
A scan lists possible weaknesses. We confirm each finding with a proof of concept and show what an attacker could do with it.
Do you test APIs and cloud environments?
Yes. The scope covers web and mobile apps, REST and GraphQL APIs, AWS and Azure environments and infrastructure.
Do you help fix what you find?
Yes. We engineer fixes down to the affected code and retest them.
How long does it take and what does it cost?
The Security offer on the Access page states a delivery estimate of 5 business days. Plans and prices are on the Access page.
