Threat-led services, defender-ready outcomes

Who we are

Threat-led experts focused on defender outcomes

Nemesis Group blends offensive tradecraft with collaborative detection engineering so you leave every engagement with tuned alerts and clear playbooks. We maintain a defender-focused presentation with high-contrast, blue-forward delivery.

Our teams operate with evidence-first reporting, pre-agreed rules of engagement, and executive-ready narratives that translate technical findings into business impact.

How we work

Engagements map to ATT&CK, include purple collaboration, and prioritize detections and fixes you can deploy quickly.

  • Realistic objectives with defined success criteria
  • Attack path evidence, replay steps, and remediation owners
  • Detection tuning during the exercise—not afterward

  • Hardening guidance that protects critical infrastructure first
  • Runbooks and playbooks ready for SOC, engineering, and leadership
