The 2024-2025 UK record

None of them were brute-forced. Every one started with a person, a password, or a supplier.

Read the names from the last two years. Jaguar Land Rover went dark on 31 August 2025, in what the Cyber Monitoring Centre rates the most damaging cyber incident in British history. Marks & Spencer lost around £300 million in operating profit over Easter and switched off online orders. The Co-op confirmed attackers accessed the data of 6.5 million members and stood over empty shelves across its stores. Attackers hit Synnovis in June 2024, and NHS England recorded more than 10,000 cancelled or postponed acute appointments and over 1,700 cancelled operations across affected London trusts. An attacker phished a person, reused a leaked password, or walked in through a supplier nobody was watching. You do not need a JLR-sized target to share their weakness. An attacker breached 43% of UK businesses in the last year, and phishing did most of it, according to the Cyber Security Breaches Survey 2025/2026 (DSIT). An auditor checks whether your controls exist on paper. An attacker checks whether they hold. We run the second test.

White-label delivery

We run the engagement under your brand. The client in London stays your client and never sees RTP. You set the price, you keep the margin.

Outcome: enterprise-grade work shipped under your name.

Red team assessment

We attack like a real adversary would: external surface, people, applications. Then we hand you the walk-through and the fix.

Outcome: a ranked list of the doors, with evidence.

Penetration testing

Targeted, scoped testing of a system, application or network. Clear findings, clear remediation, signed off by a CREST operator.

Outcome: a board-ready report you can act on.

A year of retests

One test, then we re-check as you change. RTP Robin keeps watch so what you see is exploitable today, never a snapshot from last quarter.

Outcome: cover that moves with your business.

What partners and clients say

Names withheld. The work is confidential, so these are anonymised: a role, a sector, a city. The voices are real to the kind of partner and client we work with in London.

  • We resell their red team under our badge. The client gets CREST-certified work, we get a wholesale price that holds our margin, and we have never been undercut on a renewal. It let us keep accounts we would have lost to a bigger name.

  • We are FCA-regulated, so a tick-box was never going to satisfy me. They got into our customer portal through a path our last pen test missed, then handed me a report the board and our auditor both used as-is. The fixes came ranked, not a flat list of 200 issues.

Questions, answered

The honest answers

Every assessment starts where an attacker would: outside, watching, looking for the one door left ajar. We find it, then we show you the walk-through.

What does it cost?

Start with a free audit: a short call and a free first-look scan. We scope the paid red team with you on the call, so you pay for the work and nothing else. For context, the average most-disruptive breach cost a medium or large UK business around £10,830 in 2024 according to the Cyber Security Breaches Survey (DSIT), and M&S lost roughly £300 million in 2025. The work costs far less than the breach it prevents.

Will this disrupt our operations?

No. We agree the rules before we start: what is in scope, what is off-limits, what we never touch. Nothing gets deleted or broken. Your business runs as normal while we test. You decide whether your team knows it is happening or finds out from the report.

Is this legal?

Yes. Every engagement runs under a signed authorisation that you sign first. We test only what you own and approve, within the boundaries we set together. The work follows CREST-aligned methods and UK law throughout.

We passed Cyber Essentials and our audit. Why do we need this?

An audit checks whether your controls exist on paper. An attacker checks whether they hold under pressure. Those are different tests. JLR, M&S and the Co-op all had certificates and budgets, and all three went dark. An attacker breached 43% of UK firms last year, per the Cyber Security Breaches Survey 2025/2026 (DSIT). We run the test the auditor cannot.

What do we actually get?

A prioritised list of how an attacker would breach you, ranked by how easily each door opens, with the exact fix for each one. It is written so your board, your FCA or ICO reporting, and your Cyber Essentials Plus assessor can all use it directly. No 100-page jargon dump. The finding first, then how to close it.

What happens after the free audit?

You fix the doors we found, in priority order. If you want continuous cover, RTP Robin turns one paid test into a year of unlimited re-tests, with human verification on every finding, so you never go stale between tests. Most firms start with the free audit and move up once they have seen what we find.
