If none of this sounds familiar, you probably don't need it.
The deal is stuck behind a security review
An enterprise customer has sent a 200-line questionnaire, or asked for your ISO 27001 certificate. Procurement won't move until it's answered.
Nobody in the building has done this before
There's no ISMS, no risk register, no Statement of Applicability, and no obvious person to own any of it.
The quotes came back at £20k and six months
Which is real money at your stage, for something you can't yet tell is being done well or badly.
You bought a tool and it didn't help
A dashboard turned green and you still couldn't answer the auditor's third question. The tool was never the hard part.
What a founding place gets you
The same platform everyone gets, at a rate nobody after you will get.
The full platform, not a cut-down version
ISO 27001 management system, UK and EU GDPR essentials, registers, evidence vault, audits and management review — unlimited users on every plan.
Onboarding with a lead auditor
Your setup session is with me, not an account manager, so the scope and the Statement of Applicability are right from day one.
The price locked for two years
Your founding rate holds for 24 months, so a renewal increase can't land on you next year.
Modules when you need them
28 framework modules — SOC 2, HIPAA, PCI DSS, ISO 22301, TISAX, EU AI Act and more — added at any point without a rebuild.
What it costs
The first 20 paying customers on a Starter, Business or Scale annual plan take 20% off the tier price, locked for 24 months. If 20 places are not taken the offer closes on 31 March 2027 regardless.
- ✓20% off the Starter, Business or Scale plan price, held for 24 months
- ✓14-day free trial first, no card needed — you only pay once you've seen it working
- ✓Unlimited users at every tier, so growing the team doesn't grow the bill
- ✕Certification body audit fees are yours — those are paid direct to your auditor and I can't waive them
- ✕Penetration testing and Cyber Essentials assessment fees sit outside the offer
- ✕Modules are always at list price — the founding rate applies to the plan price only
- Annual plans only. Month-to-month is at list with a 10% premium and cancels any time.
- Modules are always at list — the founding rate applies to the tier price only.
- Enterprise is outside the offer.
- Not combined with any other discount; if you also qualify for the charity, education or two-year prepaid discount you take whichever is better.
- From month 25 the list price in force at the time applies, disclosed at signup and in the order, with the CPI + 2% renewal cap from then on.
Who it's for
20 places, and I'd rather be straight now than three weeks in.
A good fit
- ✓UK or EU, from a founding team up to around 500 employees
- ✓A real certification or customer deadline you're working towards
- ✓Someone internal who can own the management system day to day
- ✓Happy on an annual plan — that's what the founding rate is for
Not a fit
- ✕Wanting month-to-month billing — that stays at list price
- ✕Needing a certificate in under eight weeks — that isn't a thing I can honestly promise
- ✕Enterprise groups over 500 employees — those are quoted separately, and the offer doesn't apply
- ✕Looking for someone to run it entirely for you with no internal owner
How it works
No discovery call with a rep, no sequence of nurture emails.

Get certified
You keep working in the platform, and I'm on the end of the phone when the auditor asks something awkward.
Who you'd be working with

I'm Simon Green, founder of Sentinel42. 20 years experience in GRC — most of it spent getting organisations through the exact process this platform runs.
I've taken a UK SaaS provider to ISO 27001 certification and SOC 2 Type 2 attestation as its Head of Information Security, and worked across the NHS, financial services and energy. I sit on the other side of the table too, as a qualified lead auditor — which is the main reason I know which parts of this genuinely matter and which parts are theatre.
