SpecterOps

SpecterOps is an adversary-focused cybersecurity company built to help organisations understand how threat actors manoeuvre against them. Founded by former US Department of Defense red team operators, the firm brings a military-grade adversarial analysis mindset to commercial security testing.

SpecterOps is CREST-accredited and offers penetration testing, red team engagements, and purple team assessments. Their red team methodology is rooted in real-world adversary tradecraft, focusing on post-initial access techniques including lateral movement, privilege escalation, and Active Directory attack paths. Their purple team service provides actionable results that drive immediate improvements to detection capabilities.

The company is also known for creating BloodHound, the widely used open-source tool for mapping Active Directory and Azure attack paths. BloodHound Enterprise is their commercial product for identity attack path management. SpecterOps releases numerous free and open-source security toolsets and provides training in adversary tactics, techniques, and procedures.
