Evidence operations without the annual scramble

Marrow Grange Compliance builds software for teams that must answer questions about their own controls on demand. We collect evidence from the systems you already run, keep it mapped to the frameworks you are assessed against, and make the present state of a control something you can query rather than reconstruct.

The problem we work on

Assurance is still largely run as an annual reconstruction. Screenshots are gathered by hand, spreadsheets drift, and a team spends weeks assembling a picture of a system that has already moved on. The deeper cost is not the effort but the blind spot: on an ordinary working day, nobody can say whether a given control is actually holding.

What we provide

• Scheduled, read-only evidence collection from cloud accounts, identity providers, ticketing systems and code hosts
• Control definitions maintained independently of any one framework and mapped outward, so a single piece of evidence satisfies every scheme it belongs to
• Exception registers with named owners, expiry dates and a full trail of who accepted what
• Time-boxed reviewer workspaces that let an assessor read evidence without touching the underlying systems

Who we serve

Our customers typically run between two hundred and four thousand people in financial services, health technology and public sector supply chains. They share a shape: a small assurance function accountable for a much larger control environment, and an engineering organisation with no patience for manual screenshots.

Engagement

Work begins with a scoping session covering frameworks in play, systems holding evidence, and the review calendar. Most teams have a first framework mapped and collecting within three weeks. Historical evidence does not need migrating; prior artefacts attach as static records and are superseded as live collection takes over.
