Common Sense Cyber Security

Amethyst Cyber Group

Penetration testing, Cyber Essentials, red teaming, consultancy, and readiness support for organisations that need clear evidence of their security posture.

Penetration Testing

Find exploitable weaknesses before attackers do.

Web, API, mobile, infrastructure, cloud, wireless, and authorised physical testing with clear evidence and remediation advice.

Managed Vulnerability Scanning

Keep visibility between point-in-time tests.

Scheduled scanning, triage, reporting, and remediation tracking across external, internal, cloud, and authenticated assets.

Red Teaming

Test resilience against realistic attack paths.

Objective-led exercises that test controls, detection, response, identity resilience, segmentation, and authorised physical scenarios.

Purple Teaming

Improve detection through joint attack and defence work.

Collaborative exercises that help defenders observe techniques, tune controls, validate telemetry, and improve response workflows.

Governance and Compliance

Turn technical controls into usable evidence.

Cyber Essentials certification, optional readiness, CIS alignment, build reviews, supplier assurance, and control evidence support.

Standards we work to

  • Cyber Essentials certification
  • CIS Benchmark alignment
  • IPI professional standards
  • Joint Code of Ethics
  • Evidence-led reporting
