Manual, adversarial testing of your iOS and Android apps — insecure storage, weak transport, tampering and backend authorisation gaps exploited on real, rooted and jailbroken devices. NCSC CHECK-certified testers.
Book a scoping call See the methodologyA published binary can be downloaded, decompiled and instrumented by anyone. Every secret embedded in the app, every trust decision made on the device and every assumption your API makes about "the official client" is available to a patient adversary.
Rooted and jailbroken devices, Frida hooks and traffic proxies let an attacker bypass certificate pinning, defeat local checks and observe exactly what your app does with your data.
API keys, third-party credentials and hardcoded tokens are recoverable from any distributed app. If your backend trusts them, so can an attacker.
Automated tools flag known library versions and missing flags. The flaws that hurt — client-side trust abuse, session handling gaps, weak re-authentication on sensitive actions — need a human adversary.
Mobile apps hold session tokens, personal data and payment flows in an environment you don't control. The flaws that dominate are the kind a careful manual test finds first.
Of mobile applications would fail even basic security testing, per industry assessment research.

Mobile app penetration testing is a controlled security assessment in which qualified testers analyse and attack iOS and Android applications, their local storage, communications and backend interactions to uncover exploitable weaknesses that could expose data, sessions or sensitive functions.
Tests applications in hostile device conditions, including rooted and jailbroken environments where local controls can be manipulated.
Examines storage, caches, logs, keychains and transport paths for credentials, tokens and sensitive information that should remain protected.
Challenges certificate pinning, anti-tamper controls, client-side trust and instrumentation defences the way a determined attacker would.
Tests the APIs and services behind the app because mobile security depends on what the server trusts, not just what the binary contains.
Mobile penetration testing puts a certified human attacker at your app — decompiling the binary, instrumenting it on rooted and jailbroken devices, intercepting its traffic and attacking the backend APIs it relies on. The goal is to prove what actually hurts: extracted session tokens, bypassed biometric checks, replayable transactions, cross-user data exposure.
Our CHECK-certified testers work from the same mindset as a real adversary: map what the app trusts, abuse what it assumes, and prove impact — can a hooked device bypass local authorisation? Does a revoked session still work offline? Can the app's traffic be replayed against your API without the app at all?
The result is a report written for decisions: every finding with an attack chain, business impact, severity you can defend, and remediation your developers can implement.
As a UK provider working under the NCSC CHECK scheme, our testing is recognised across UK government, financial services and regulated industries — and maps directly to Cyber Essentials Plus, ISO 27001, UK GDPR, DORA and NIS2 obligations.
A scanner reads your manifest. A penetration tester reads your app the way a hostile device does — and finds the trust assumptions no static check will ever flag.
We audit app sandboxes, keychains, logs, backups and caches for tokens, PII and credentials that survive where they shouldn't.
NCSC CHECK-certified professionals instrument your app by hand on rooted Android and jailbroken iOS devices — with the judgment to spot what a scanner scores as noise but an attacker scores as a way in.
Platform-specific weaknesses — Android exported components and cleartext traffic, iOS pasteboard leakage and keychain handling — tested on each.
SSL pinning defeat, root/jailbreak detection evasion, Frida instrumentation, repackaging and anti-tamper assessment — the attacks your app will actually face.
Every finding ships with the reproduction, the code-level cause and the concrete fix — written so your team can reproduce, understand and close it without a call.
Fixes often introduce new flaws. We re-verify every remediation against the original attack chains at no extra cost — so your report ends clean, not half-patched.
Every engagement follows the same business-first process — scoped precisely to the systems that matter to your P&L.
Prompt injection, model abuse, RAG data leakage and agent tool misuse — tested before your AI goes live.
ApplicationsAuthentication flows, business logic and the full OWASP Top 10 — attacked the way a real adversary would.
ApplicationsREST and GraphQL endpoints, token handling, and authorisation gaps exposed through the interfaces your partners rely on.
NetworksExternal perimeters, internal networks and Active Directory — from internet-facing foothold to domain compromise.
ApplicationsiOS and Android apps dissected for insecure storage, weak transport and tampering risks on real devices.
NetworksCorporate Wi-Fi, rogue access points and WPA2/WPA3 weaknesses — tested on-site, at your offices.
Six phases, from scoping through to ongoing assurance. Every phase is documented, every finding is actionable.
We inventory your app builds, backend endpoints and authentication flows, agree test devices, builds and environments, and set the rules of engagement — so testing never collides with your production users.
Manual adversarial testing against the OWASP MASVS and Mobile Top 10: storage and keychain analysis, transport security, tampering and instrumentation, session handling and backend authorisation — chained into real attack paths.
Every finding written as an attack chain — the technique, the data or privilege reached, the business consequence — with reproduction steps, evidence, MASVS mapping and a fix your developers can act on. Reports land within 5 working days.
We stay with your developers — by call or on-site — reviewing patches, advising on architecture and confirming each fix closes the flaw rather than redirecting it.
We replay the full attack chains, not just the individual findings — because a patched flow is worthless if the same flaw survives on a sibling path.
Apps ship weekly. We re-test on your release cadence — every sprint, month or quarter — so new builds arrive tested, not untested.
Fixed-fee, CHECK-certified, scoped around your real builds and endpoints. One call is enough to size it.
