Who We Are

Act Before You Need to React.

"We exist to answer one question: do your defenses actually work?"

SCYTHE is the leading Adversarial Exposure Validation platform, continuously testing whether your defenses actually work against the threat actors targeting your industry right now.

We don't test in sandboxes. We run real MITRE ATT&CK-mapped adversary campaigns in your live environment, validating your EDR, SIEM, and SOC end-to-end, on a continuous schedule. No surprises. No assumptions.

Who We Serve

Built for the Enterprises Adversaries Target Most

SCYTHE is trusted by security teams defending some of the world's most complex and targeted environments — from global financial institutions to critical infrastructure operators and federal agencies.

Financial Services

Banks, insurers, and asset managers use SCYTHE to validate controls against the nation-state and ransomware actors targeting global capital markets.

Critical Infrastructure

Energy, utilities, and manufacturing operators validate across IT/OT boundaries — safely, without production risk — against actors like VOLTZITE and Sandworm.

Federal & Defense

Government agencies and defense contractors use SCYTHE to meet RMF and CMMC requirements and build repeatable, evidence-based validation programs.

Healthcare

Health systems validate their detection and response capabilities against ransomware groups that consistently target patient data and clinical operations.

What SCYTHE Does

Continuous Validation. Real Adversaries. Your Actual Environment.

Your EDR vendor validates their product in their lab. SCYTHE validates it in yours — against the specific techniques being used against your industry, right now. That's a different test with a different answer.

Named Threat Actor Emulation

Run full kill-chain campaigns mapped to APT28, VOLTZITE, Sandworm, and more — in your live environment, not a sandbox.

EDR & SIEM Validation

Know whether CrowdStrike, Splunk, Sentinel, or QRadar are actually detecting what they should — before an attacker finds out they aren't.

IT / OT Boundary Testing

Production-safe, agentless deployment for OT/ICS environments — covering the convergence points real adversaries exploit.

Purple Team Collaboration

Red and blue teams see results simultaneously. Gaps get fixed in the session — not three weeks later in a debrief.

The Team

Built by Practitioners, for Practitioners

SCYTHE's leadership team brings together decades of offensive security, enterprise technology, and federal defense experience. We've been on both sides, and we built SCYTHE to solve the problems we couldn't solve with anything else on the market.
