Security & trust

Security and data protection

Composure holds your customers’ contact details and the facts of their incidents. Here is where that data lives, how it is protected, and what we commit to in writing.

Hosted in London Two-factor sign-in for admins A person approves every AI draft
Infrastructure and access

UK-hosted, and clear about everything else

Your data is stored in the UK. Where any supplier processes it elsewhere, we say so.

Where your data lives

Stored in the UK (London). Email delivery runs in the EU (Ireland). AI drafting, text messages and WhatsApp messages are processed in the United States under UK transfer safeguards. Every supplier, what it handles and where is on our sub-processors page.

Encryption

Encrypted at rest with AES-256 by our hosting provider (Supabase, London), and in transit with TLS. Every connection uses HTTPS. Backed up automatically every day; backups are kept for 7 days.

Two-factor sign-in

Admins must sign in with an authenticator app, and the server enforces it, not just the browser. You can require it for all your staff, and for a customer’s portal contacts.

Sign in with Microsoft

Your team can sign in with their Microsoft accounts, so your own Microsoft security policies, including multi-factor and Conditional Access, apply. People can be added and removed automatically from your Microsoft groups.

Read-only connections

Connecting HaloPSA or Microsoft Entra ID asks only for read access, and our setup guides show you how to grant exactly that. The credentials you give us are stored encrypted.

Each MSP walled off

Every MSP’s data is separated inside the database itself, not just hidden by the app. One MSP can’t read another’s data, even if a screen had a bug, and a customer’s portal contacts see only their own organisation.

Role-based access

People reach only the data and actions their roles allow, and can hold several roles. Every rule is enforced in the app and again in the database.

Composure support access

If our support team needs to see your account, access is time-limited and recorded, and your admins can see it in the app.

A record of every send

Who sent each communication, to whom, and who approved it is recorded with the time on each incident and report. Privileged actions, such as password and two-factor resets and support access, are recorded too.

AI safeguards

AI-assisted, never AI-autonomous

The AI drafts. A person on your team decides what your customers receive.

A person approves every draft

Every AI-drafted update, maintenance notice and RCA waits for a person to approve it before it is sent. Two automatic emails are the exception: “Service restored” (our fixed wording, which you can skip) and the final “Resolved” email (your own template), both lightly polished by AI and checked so no facts change.

Careful wording, checked twice

The AI is told to keep hostnames, blame and speculation out of customer updates. On Communicate, each RCA is also scored by a separate AI reviewer, and wording that carries liability risk needs executive sign-off.

Your data isn’t used to train AI

Our AI provider does not train on the incident details we send it, and deletes them within 30 days.

Data protection

Your data, your rights, in writing

What we commit to is in our Data Processing Agreement, under UK GDPR.

Data Processing Agreement

Our DPA is part of the agreement you accept at sign-up. We’ll countersign a copy on request.

Sub-processor changes

We give 30 days’ notice before adding a sub-processor, by email to your admins, and you can object.

Requests from individuals

Your admins can find, correct, export and delete contacts and users in the app.

Retention

How long we keep each kind of data is set out in our Privacy Notice and DPA.

Our commitments

If a personal data breach affects your data, we tell you within 48 hours, so you can meet your own 72-hour deadline
We never sell your data or share it for anyone’s marketing
We self-assess against the OWASP Application Security Verification Standard (four times since July 2026, every finding and fix recorded), and automated checks test the database’s security every day
Honest about what’s next: an independent penetration test hasn’t been carried out yet, and we’re not yet ISO 27001 or SOC 2 certified. SOC 2 Type I, then ISO 27001, is our plan
Access to production is restricted to the people who run the service
