Services  /  Application security

Your app, tested by an adversary.

Web, API, and mobile applications, tested the way a real attacker would, by hand, across every layer, from access control to business logic. Every finding comes with a working proof-of-concept and a clear fix.

The point

You'll know exactly how you'd be breached.

Not a list of theoretical CVEs from a scanner. A hand-tested, exploit-backed picture of what a real attacker would do to your application, and the specific things to fix first.

What we test

Every layer, by hand.

Aligned to the OWASP testing guide, then pushed past it into the logic and identity abuse scanners never reach. Hover to explore.

01 · Authorization

Broken access control

The web's number-one risk, and the one automated tools miss most. We test every object, every role, and every identifier by hand, horizontally and vertically.

$ GET /api/v2/orders/40219 cookie: userA
200 OK owner: userB ← not yours

02 · Input validation

Injection, everywhere

SQL, XSS, SSTI, and command injection, tested across every input, including the ones your framework claims to handle for you.

CRITSQL injection · report export
HIGHStored XSS · comment field

03 · Business logic

Abuse cases no tool finds

The flaws unique to your app: negative quantities, skipped steps, replayed requests, race conditions. No scanner understands your workflow. We do.

04 · Authentication

Paths to account takeover

Login, MFA, password reset, and session handling, the full set of paths a real attacker chains to become one of your users.

HIGHPassword-reset token reuse
MEDMFA not enforced on API

05 · API testing

REST & GraphQL

Object-level authorization, mass assignment, introspection leaks, and rate-limit bypass, the API-specific classes that web scanners skip.

How we work

Manual-led, evidence-first.

01

Recon & mapping

Enumerate the app, its stack, and every input, role, and workflow.

02

Manual + tooled testing

Human-led testing across every domain, Burp-assisted, never scanner-only.

03

Exploit & prove

Chain findings into a working, reproducible proof-of-concept.

04

Report & retest

A prioritised report, a live debrief, and a free retest of your fixes.

Proof · Government

Upload to remote code execution.

An unsafe file-upload turned into remote code execution on the server, alongside IDOR flaws exposing other users' records, each proven on the live application, with the exact steps to reproduce and fix.

Technical report

Every finding with evidence, impact, and remediation.

Remediation pack

Concrete fixes, prioritised by what to close first.

Detection recipes

Rules so your SOC can spot the same attack next time.

Live findings stream

Critical issues shared the moment we find them.

Retest letter

Written verification that your fixes actually hold.

Questions, answered

The usual questions.

How long does a web app test take?

Most engagements run one to two weeks depending on scope. You get a fixed timeline and a fixed number before we start.

Production or staging?

Either. We agree on the environment, test windows, and safety rules together in the scoping call.

Will testing disrupt the application?

No. We test carefully and never run destructive payloads without explicit, written sign-off.

What do you need from us?

A scope, environment access, and test accounts for each user role. We handle the rest.
