Our Red Teaming services simulate advanced persistent threats to test your organization's detection and response capabilities comprehensively.
ReactiveZero's Red Teaming operations are designed to rigorously test your organization's defensive capabilities against sophisticated, multi-faceted attacks. We emulate the tactics, techniques, and procedures (TTPs) of real-world adversaries to provide a realistic assessment of your security resilience, identify blind spots, and improve your incident response readiness. For continuous, automated adversary emulation between engagements, explore our R0 autonomous red-team appliance.
Every engagement runs as a controlled adversary emulation. Here is the operation opened up phase by phase, with the moments your defenders are meant to catch us.
Each phase names the defensive signal your blue team is placed to catch, the same map we walk together in the debrief.
An assumed-breach engagement starts from the realistic premise that an attacker is already inside — through a phished laptop, a leaked credential or a malicious insider — and asks what happens next. Rather than spending the budget getting in, we begin with a foothold and focus on what matters: how far an adversary can move, what they can reach, and whether your team detects and responds in time. Mapped to MITRE ATT&CK, it is an efficient way to test detection and response and suits TIBER-NL and DORA TLPT scenarios.
A full-spectrum red team operation emulates a real adversary from start to finish. We begin with external reconnaissance and open-source intelligence, gain initial access through phishing, exposed services or physical and social engineering, then establish command-and-control and work towards agreed objectives such as reaching a crown-jewel system or dataset. Throughout, we test whether your people, processes and technology detect and respond. Every action is mapped to MITRE ATT&CK and safely deconflicted with your team, producing a realistic measure of resilience for TIBER-NL and DORA TLPT programmes.
Purple teaming turns an adversarial test into a collaborative one. Our red team executes attack techniques side by side with your blue team or SOC, so defenders can watch each step, confirm whether their tooling generated an alert, and tune detections on the spot. We work methodically through the MITRE ATT&CK techniques most relevant to your threat model, measuring detection and response coverage as we go. You finish with a clear map of what you catch, what you miss and concrete, validated improvements to your logging, alerting and playbooks.
