Step 1 of 5 0%

01 // Detection & Response

These controls determine how quickly you detect and respond to threats.

e.g. CrowdStrike, SentinelOne, Defender for Endpoint

Security Operations Centre or Managed Detection & Response service

Written plan that's been exercised/tabletop tested in the last 12 months

02 // Access Control

Controls that limit attacker movement and privilege escalation.

Multi-factor authentication on email, VPN, admin portals, cloud apps

Controlled admin access, credential vaulting, just-in-time access

VLANs, micro-segmentation, or zero trust network architecture

03 // Prevention & Hygiene

Proactive controls that reduce your attack surface.

Advanced email filtering, DMARC, sandboxing, link protection

Regular scanning, patching cadence, prioritised remediation

Regular phishing simulations, security training for all staff

04 // Recovery Readiness

Your ability to recover when (not if) something goes wrong.

Regular backups with tested restores, offline/immutable copies

05 // Organisation Profile

Industry and size affect breach costs and attacker targeting.
