Mercator

Judgement

What it is

Complete system

What it does

Maps an organisation's information system from business processes down to physical infrastructure, following the ANSSI cartography method, with dependency views and CVE links.

Adopt it when

A security or compliance team must produce and maintain an information-system map for NIS2, ISO 27001 or French ANSSI requirements.

Watch out

Its value depends on someone keeping the map current by hand or through imports; it does not discover assets on its own.
