Your Martyn's Law preparedness, recorded and evidenced - not just assumed.
Gryphon walks your team through every requirement of the Terrorism (Protection of Premises) Act 2025 — capturing decisions, justifications, and improvement plans. The result: a live preparedness dashboard you can stand behind.
For single venues and multi-site operators · No security expertise required
Does the Act apply to you?
The Act covers a wide range of premises with a public-facing use, with proportionality applied throughout.
Local authorities
Mixed-tier portfolios under one account.
Hospitality & leisure
Venues where attendance and layouts shift.
Schools & places of worship
Standard tier with large, open-access crowds.
Healthcare & retail
Complex sites with high footfall and turnover.
Out of scope
Fewer than 200 expected
No statutory obligations. Good practice is still worthwhile.
Standard tier
200 to 799 expected
Notify the SIA. Procedures in place for evacuation, invacuation, lockdown, and communication.
Enhanced tier
800 or more expected
All standard tier duties, plus public protection measures, a documented record submitted to the SIA, and a designated senior individual.
The threshold is based on who you reasonably expect to be present. Gryphon's scope assessment walks you through it.
The weight responsible persons are carrying
Most organisations in scope are not security specialists. They are being asked to translate statutory guidance into something workable — and then keep it that way.
128 pages of guidance
Statutory text written for regulators, not for the people who actually run buildings.
Scope has nuance
Reasonable expectation, not maximum capacity. Easy to land on the wrong starting point.
Decisions need reasoning
The SIA considers why you decided something, not only what you decided.
Records drift
Layouts change, events change. A static document goes stale fast.
Deadlines creep up
Enhanced tier requires resubmission to the SIA within 30 days of a material change.
Staff change, knowledge doesn't transfer
Procedures documented in someone's head aren't procedures at all.
One platform, calmly maintained
Gryphon gives organisations the structure to work through each obligation in the right order — and the prompts to keep it current as things change.
Plain-English guidance
Every field explains what the law expects and what a thoughtful answer looks like.
Structured, section by section
The Act broken into ordered steps, so nothing is missed and nothing is rushed.
Reasoning captured
Decisions, intent, and timeframes recorded — not just ticks in boxes.
Stays current
Change detection, deadline tracking, periodic review prompts. Maintained, not filed away.
How it works
A guided process from first question to ongoing record.
Establish your position
Answer guided questions about your premises. Gryphon determines your tier and explains what applies.
Work through each requirement
Section by section, with context. Record what is in place, what is planned, and when.
Maintain it as a living record
Material changes flagged. Submission deadlines tracked. Reviews prompted. No last-minute scramble.
Why responsible persons choose Gryphon
The point isn't to look prepared. It's to genuinely be prepared — with a record that reflects the work done.
An evidencing record that holds up
Decisions, reasoning, and arrangements captured in one place — defensible if asked.
Preparedness as a process
Not a one-off document. A maintained record that moves with your organisation.
Steady progress, no panic
Build the record over months, calmly, instead of producing it in haste before an inspection.
Designed for the responsible person
For facilities managers and operations leads — no security-specialist background assumed.
Plans where there are gaps
Where something isn't yet in place, record what your organisation intends to do, and when.
Deadlines tracked for you
30-day resubmission windows and review cycles surfaced before they become a problem.
Show your organisation takes security seriously
Gryphon gives you a clear, structured record of your compliance activity — built around the obligations that matter under Martyn's Law.
Evidence that holds up
A documented record showing your organisation engaged seriously with its security responsibilities — exactly what the SIA expects.
Works alongside your advisors
Gryphon complements professional security advice. Use it alongside your consultants — it's the record-keeping layer they don't provide.
You stay in control
Your organisation owns the record. Gryphon supports the responsible person — structuring the process so nothing falls through the cracks.
Put down the spreadsheet. Pick up the platform.
The calmer route to compliance is also the more defensible one.
