We know where to look.
What we review

One audit. Four lenses.
No blind spots.

Your app is more than its code. We examine the full experience, from the first click to the failure states your AI builder forgot.

⌁01

Security

Authentication, authorization, exposed secrets, database rules, APIs, dependencies and abuse paths.

  • Can users access what they shouldn’t?
  • Can data or money be manipulated?
◎02

User experience

Clarity, navigation, responsive behavior, accessibility and the moments that make users quit.

  • Can a new user succeed unaided?
  • Does every state explain what’s next?
◇03

Payments & trust

Checkout, subscriptions, webhooks, entitlements, cancellation and the signals that earn confidence.

  • Do payments change access safely?
  • Does your product feel credible?
↻04

Edge cases

Failures, retries, duplicates, empty states, expired sessions and everything outside the happy path.

  • What happens when services fail?
  • Can users recover without support?
What we catch

Common issues that
cost trust and revenue.

These are examples, not a fixed checklist. We follow real user journeys and investigate every relevant issue we discover within your selected audit scope.

Web applications only. We currently audit browser-based web apps and responsive mobile-web experiences. Native iOS and Android applications are not accepted. After payment, we will email you about the NDA, secure access and the remaining onboarding details. Large, regulated, multi-product or unusually complex systems may require a custom scope. We will always confirm this before beginning.
Good to know

Questions,
answered.

Still unsure which audit fits? Email us and we’ll point you in the right direction.

Do you use automated scanners?+

We use professional tools where useful, but every audit is led and verified by experienced humans. You receive real judgment and context, not an exported scanner report.

Will you sign an NDA?+

Yes. We can provide a mutual NDA before you share credentials or repository access. We can also review your standard NDA.

Do you audit native mobile apps?+

Not currently. AuditFlare accepts browser-based web applications, including responsive mobile-web apps, but not native iOS or Android apps.

Will you fix the issues you find?+

Your report includes practical remediation guidance. If you want hands-on implementation, we can scope a separate fixed-price remediation sprint after the audit.

Is this a certified penetration test?+

No. These are launch-readiness, UX and application-security audits. Compliance attestations and formal enterprise penetration tests require a separately scoped engagement.
