Our review
This is a privacy-first take on GRC. The page lists Proteus-Cyber Ltd, 20-22 Wenlock Road, London N1 7GU, England and Wales company 07239733.
The software is marketed as Proteus NextGen. We went through the home, solutions, terms and privacy pages on 4 November 2026.
Which London entity
English law and the English courts govern the site terms.
The terms give a registered office in Maidenhead while the footer shows London; we could not square the two.
Scope next to Archer
Listed topics: data mapping, PIA and DPIA, risk assessment, vendor risk with transfer impact assessments, consent, breach notification, and continuous testing of controls.
Archer reaches across enterprise risk, audit and compliance. Proteus-Cyber stays on privacy.
Legal position built into controls
The vendor says controls are picked automatically, based on criteria the customer sets for each privacy regulation.
Templates exist for GDPR and CCPA, so non-European law is covered too.
Points against
Neither amounts nor data location appear. Audit and enterprise risk modules are not on show, and the footer and terms disagree on the address.
Who Proteus-Cyber fits
Privacy officers and compliance staff who need data mapping, DPIA and vendor assessments together.
