What we
test for.

Find the weaknesses that put your applications, accounts, and customer data at risk. Expert-led security testing, powered by frontier AI.

From your domains to the actions behind sign-in.

We look everywhere, to protect what matters to your business.

We tailor the checks to your application, using OWASP web and API testing guidance to investigate the weaknesses attackers could exploit.

Examples of web application and API testing, with the business risk each area addresses.
Testing area	What we look for	What’s at risk
01Domains & public exposure	Exposed subdomains, revealing files and error messages, weak TLS settings, and known vulnerable software.	Information that gives an attacker a way in.
02Sign-in & sessions	Weak login and password-reset flows, exposed tokens, and sessions that can be reused or taken over.	Your customers’ and employees’ accounts.
03Permissions & roles	Whether one user can reach another’s records, cross customer boundaries, or perform administrator actions.	Private data and privileged access.
04Inputs & file handling	Injection, cross-site scripting, unsafe uploads, file-path traversal, and requests to unintended internal services.	Application data and the systems behind it.
05API security	Missing access checks, sensitive data in responses, and writable fields that let users change protected values.	The data exchanged between your services.
06Business logic	Manipulated prices, reused discounts, skipped approval steps, and simultaneous requests that break your rules.	Revenue and the integrity of key workflows.

These are examples of the checks we can scope for your application. The test plan reflects your systems, access, and priorities.

Beyond the public homepage

With agreed test accounts, we explore how different users move through your application and inspect the API requests behind their actions.

We test whether the permissions hold when a request changes, a step is skipped, or smaller weaknesses are combined.

For example

We compare access across test accounts and check that the application enforces ownership at the API, as well as in the interface.

Autonomous testing finds potential issues. EXP Frontier reviews the evidence and helps your team move towards a verified fix.

01
Investigate the issue.
Explore the agreed application and test how it responds to suspicious inputs, requests, and user actions.
02
Review the evidence.
Confirm the finding, explain its impact, and give your team a clear recommendation in the EXP Portal.
03
Verify the change.
Your team deploys the fix. We retest the issue and record the reviewed result.
