(Why founders sign us for security)

You need penetration testing services. We ship the test and the receipts your acquirer asks for.

Thirty-one pen tests since 2019. Senior engineers only, no junior hand-off. The report we hand you is the one procurement clears, the auditor signs, and the acquirer’s CTO reads without flinching.

The founder this page is for60-page questionnaire · held pen-test asked for · deal on hold

Nadia’s biggest deal stalled on one line in a security form. “Attach your latest independent pen-test report.

01

Her UK SaaS was doing fine. Then a 60-page vendor security questionnaire landed, and the one line she couldn’t answer held the contract: a held, independent penetration test. Two in-house engineers had run a quick scan months earlier. No scope, no methodology, no report procurement would accept.

02

We scoped it on a Monday, tested across the week, and walked her through every finding by severity. OWASP Top 10, the API surface, the cloud config, the auth flow. Each issue had a reproduction, a fix, and a retest path. The remediation roadmap, not just the holes.

03

Two weeks later the fixes were in, the retest was clean, and the report shipped with the questionnaire. Procurement cleared it in days and the deal closed at ask. This page is for the founder who recognises that paragraph.

What we test

Six surfaces, every engagement

A web application pen test that only hits the login page isn’t a pen test. We test the surfaces attackers actually use and the ones your auditor asks about. Each card maps to a section of the report you hand procurement.

Surface-01

Web application (OWASP Top 10)

Injection, broken access control, auth flaws, and misconfiguration against your live web app. Every finding carries a reproduction, a severity, and the exact fix.

Surface-02

API + authorisation testing

IDOR, broken object-level authorisation, rate limits, and token handling. We test whether one tenant can read another tenant’s data, the question your buyer cares about most.

Surface-03

Cloud + infrastructure config

Public buckets, over-broad IAM roles, exposed metadata, weak segmentation. AWS by default, comfortable on GCP, Azure and Cloudflare. The misconfig that turns one bug into a breach.

Surface-04

External + network surface

An external pen test of what the internet can reach: exposed services, forgotten subdomains, stale endpoints, leaked credentials. The surface you stopped looking at two pivots ago.

Surface-05

Mobile (iOS + Android)

Insecure storage, certificate pinning, hard-coded secrets, and the API traffic behind the app. Tested against the OWASP Mobile Top 10 when your scope includes a mobile client.

Surface-06

Report + retest included

Every engagement ends with an evidence-grade report, a remediation roadmap ranked by severity, and a retest after you ship the fixes. The held report procurement accepts.

Eight security pains we hear in every scoping call

The pain. The day-1 answer.

Every founder who emails us about penetration testing services is fighting one of these eight things. Each one stalls a deal, fails an audit, or scares an acquirer. Each one has a direct answer.

  1. 01
    The procurement bounceReport

    “Our enterprise prospect asked for a held pen-test report and we had none.”

    Evidence-grade report procurement accepts. A scoped, methodology-backed report with findings, severities, fixes, and a retest. The document that clears a vendor security review in days, not months.

  2. 02
    The cross-tenant fearAPI test

    “Can one customer read another customer’s data? We genuinely don’t know.”

    Authorisation tested at the object level. We hammer IDOR and broken object-level authorisation across your API. If a tenant boundary leaks, you hear it from us with a reproduction, not from a customer.

  3. 03
    The scan-isn’t-a-test gapMethodology

    “We ran an automated scanner once. The auditor said that’s not a penetration test.”

    CREST-aligned manual testing. Scanners find the noise. Senior engineers find the chained, logic, and authorisation bugs that matter. A defined scope and methodology, not a tool dump.

  4. 04
    The vibe-coded MVPAudit

    “We shipped fast with AI tools and now we’re raising. Is any of it safe?”

    Production-readiness pen test. AI-generated code ships auth holes, missing rate limits, and no audit log by default. We find them, rank them, and hand you the fix list before diligence does.

  5. 05
    The cloud misconfigCloud test

    “Our app is solid, but I’ve no idea what our AWS config exposes.”

    Infra config tested with the app. Public buckets, over-broad IAM, exposed metadata, weak segmentation. We test the cloud the app runs on, because that’s where one bug becomes a breach.

  6. 06
    The SOC 2 panicEvidence

    “SOC 2 wants annual pen testing and we’ve never had a clean report on file.”

    Audit-ready evidence pack. A report mapped to the controls your auditor checks, with a remediation log and a retest attestation. SOC 2 stops being a panic project and becomes a tick.

  7. 07
    The findings-with-no-fixRoadmap

    “Our last pen test gave us a PDF of problems and zero help fixing them.”

    Remediation roadmap, ranked. Every finding ships with the exact fix and a severity. Senior engineers who build for a living, so the advice is buildable, not generic. We pair with your team if you want it.

  8. 08
    The diligence flagRetest

    “The acquirer’s CTO wants proof the issues were actually fixed, not just listed.”

    Retest included in the engagement. After you ship the fixes, we test them again and attest the result. The retest line is what an acquirer’s CTO reads to close the security section of diligence.

Penetration testing toolkit · manual-first

Three tiers, one defensible methodology, findings you can reproduce.

Tier 1 is the manual testing every engagement runs on. Tier 2 is the tooling that scales the coverage. Tier 3 is the evidence and infrastructure side, because we test the cloud your app actually runs on.

Penetration testing services · honest answers

What founders actually ask before booking a pen test

Pain-first, soft-second. The questions every founder asks once a deal, an audit, or a raise depends on the answer.

The 5-day scoped audit is fixed at £8K. A full engagement, web, API, cloud and the report, typically lands between £8K and £35K depending on the surface area. We scope it precisely at the start so the number is fixed before we test. No day-rate, no scope creep, and if we can’t hit your budget we tell you in the first call.

Your auditor is right. A scanner finds the noise, the known signatures and obvious misconfigurations. A penetration test is senior engineers manually chaining bugs, testing authorisation logic, and finding the issues a tool can’t reason about. Our penetration testing services are manual-first and CREST-aligned, with a defined scope and methodology, which is what procurement and auditors actually accept.

You get an evidence-grade report: scope, methodology, every finding with a reproduction and a severity, a remediation roadmap, and a retest attestation once you ship the fixes. It maps to the controls in a SOC 2 or vendor security review. It’s the document procurement teams accept and acquirer CTOs read. Most of our clients attach it straight to the questionnaire and clear in days.

No. In thirty-one penetration tests since 2019 we’ve caused zero production incidents. We agree rules of engagement before we start, test against a staging mirror where that’s the right call, throttle destructive checks, and stay in close contact with your on-call. Safety is part of the scope, not an afterthought.

Yes, and it’s one of the most common reasons founders call us. AI-generated code ships with predictable holes: missing authorisation checks, no rate limits, no audit log, secrets in the wrong place. We run a production-readiness pen test, rank what we find, and hand you the fix list before your diligence or your first enterprise customer does.

We hand you a remediation roadmap, not a wall of problems. Every finding carries the exact fix and a severity, written by engineers who build production software for a living, so the advice is buildable. We’ll pair with your team through the fixes if you want it, then retest and attest the result. The retest is part of the engagement, not an upsell.

We’re a London studio and we keep your data in-region. Testing artefacts, evidence, and the report are handled under a signed DPA with SCCs for any cross-border processing. We’re happy to sign an NDA before you share a single endpoint. Data residency is part of the scope, and we put it in writing.

Yes. Many clients run an annual penetration test with us to satisfy SOC 2 and renew enterprise contracts, with a light advisory retainer in between for new surfaces and questions. The report maps to your controls and ships with a retest attestation each year. Notice is 30 days either way, and you can pause or resume any month with no lock-in.
