Supplier assurance
Security posture
The controls in place today, where your data is processed, who we are, and where our assurance programme stands. Written for the person who has to check.
Controls in place
- Tenant isolation
- Row-level security on every tenant table, with an adversarial test suite that seeds two organisations and attempts cross-organisation reads, updates and inserts on each one.
- Enforced in: DATABASE
- Append-only audit trail
- A database trigger blocks update and delete on the audit table — for your administrators and for us.
- Enforced in: DATABASE
- Full drafting log
- Every drafting call is recorded in full — instruction, model, response, timing — and can be reproduced later.
- Enforced in: LOG
- Multi-factor authentication
- Available to every user, and enforced at sign-in once a user has enrolled.
- Password policy
- A 12-character minimum, with complexity rules and a check against known breached passwords.
- GDPR export and erasure
- Self-serve: an administrator can export everything the organisation holds, or erase the account with a typed confirmation that cascades through the database and file storage.
- Uploaded source files
- Pre-construction packs and other uploaded PDFs are purged automatically after 30 days.
- Your documents
- Remain yours. Export any document, or everything your organisation holds, whenever you choose.
Data and processing
