Red-Team & Adversary Emulation Tools 2026
Red-team and adversary emulation tools let your offensive operators behave like a real attacker inside your environment: establishing command and control, moving laterally, escalating privilege, and running the specific techniques a threat actor would use against you. The category spans full C2 frameworks, scripted adversary emulation platforms mapped to MITRE ATT&CK, and purple-team tooling that runs attacks and measures detection in the same loop. If you run an internal red team, manage an MSSP offering, or just want proof your detections actually fire, this is where you test the assumption that your defenses work before someone else does it for you.
We cover 148 Red-Team & Adversary Emulation tools, 134 free and 14 commercial.

How to choose Red-Team & Adversary Emulation tools
- Map coverage to MITRE ATT&CK: check which tactics and techniques the tool actually exercises, and whether that overlaps the threats relevant to your industry.
- Decide what you are buying: an operator-controlled C2 framework, a scripted emulation platform, or a purple-team loop that measures detection. Most teams eventually want more than one.
- Weigh evasion against current EDR and detection stacks, since tooling that detonates loudly is fine for purple-team scoring but useless for testing realistic stealth.
- Inspect the operational footprint: how the tool manages implants, logging, and cleanup, because anything you run in production becomes a liability if it persists or leaks.
- Factor in skill level and team size: some platforms run guided, repeatable attack chains, while raw C2 frameworks assume an experienced operator who knows the tradecraft.
- Confirm licensing and authorized use fit your context, especially for client-facing engagements, regulated environments, or anything an MSSP resells.
Red-Team & Adversary Emulation Tools FAQ
Common questions about Red-Team & Adversary Emulation tools, selection guides, pricing, and comparisons.
They let security teams simulate real attacker behavior against their own environment. This includes command-and-control (C2) frameworks that operate implants and beacons, adversary emulation platforms that run scripted attack chains mapped to MITRE ATT&CK techniques, and purple-team tools that execute those attacks while measuring whether detections fire. The point is proving your defenses work, not assuming they do.
A scanner finds exposures; adversary emulation tests what happens after one is exploited. Rather than cataloging weaknesses, these tools reproduce the specific tradecraft of a named threat actor or technique: lateral movement, credential theft, persistence, and exfiltration. Compared to a one-time pentest, emulation is repeatable and often continuous, so you can rerun the same attack after tuning a detection and confirm the gap closed.
A C2 framework is the operator's tool: it manages implants, beacons, and post-exploitation actions during an engagement, optimized for stealth and operator control. A purple-team platform is the measurement layer: it fires known techniques on a schedule and checks whether your SIEM, EDR, or analysts caught them. Many programs use both, with the C2 framework driving the attack and the purple-team workflow scoring the defensive response.
A lot of mature, widely-used tooling here is open source and free, covering credential operations, scripted ATT&CK emulation, and full C2. Open source is often the right starting point for an internal team. Commercial tools tend to add managed evasion against current EDRs, hardened operational security, reporting, support, and licensing controls that matter for client-facing or regulated work. The deciding factor is whether you are building capability internally or delivering engagements at scale.
