Broad enterprise suites
Large, modular GRC platforms that cover most regimes through separately licensed modules, usually with a long implementation and a dedicated administrator.
Best fit: Large organisations with a compliance team big enough to own configuration, and budget that tolerates a multi-module licence.
Point tools
Focused products that do one job well — consent, DSAR intake, cookie scanning, vendor questionnaires — and integrate loosely with whatever else you run.
Best fit: Teams with one acute, well-bounded problem, who accept that the register tying everything together lives somewhere else.
Consultancies and managed services
People rather than software: an external DPO or advisory retainer that produces the documentation on your behalf, often in documents you then own.
Best fit: Organisations without in-house expertise who need judgement more than tooling, and who can accept that the output is a snapshot.
Compliance operations platforms
Systems that connect to what you already run, derive the records from live signals, and keep them current between audits rather than regenerating them before one.
Best fit: Teams whose systems change faster than documents can be maintained by hand, and who need to evidence a current state on demand.
