EDR Validation

Is your CrowdStrike or Defender actually working?

Your EDR is configured and running. But when was the last time you proved it would catch a real attack? SCYTHE continuously validates EDR detection coverage against real adversary behavior — so you know, not assume.

Why gaps exist

Why EDR tools miss threats even when properly deployed

A correctly licensed, correctly deployed EDR still misses threats for four predictable reasons.

Configuration drift

Security policies change, exclusions accumulate, and deployment gaps widen over time. The EDR configured six months ago is not the same EDR you have today.

Evasion techniques

Advanced adversaries use living-off-the-land techniques, process injection, and signed binary proxy execution that many EDR policies don't catch by default.

Untested detection logic

Most organizations have never run a real adversary technique against their EDR to confirm it fires an alert. They trust the vendor's ATT&CK map — not their environment.

Regression after changes

Every OS update, EDR agent upgrade, or policy change is a potential regression event. Without continuous testing, you won't know until an attacker finds the gap first.

Continuous testing at production scale

SCYTHE runs validation tests automatically on a configured schedule (daily, weekly, or triggered by change events) so you always have a current picture of your EDR coverage rather than a point-in-time snapshot from your last engagement.

Multi-stage campaign testing, not isolated techniques

Most EDR evaluation tools test single techniques in isolation. SCYTHE emulates realistic multi-stage attack chains (initial access, execution, persistence, lateral movement, credential access, exfiltration) because real adversaries chain techniques together in ways that single-technique tests miss.

Response chain validation

SCYTHE doesn't just test whether the EDR detects a technique, but it validates the entire chain: detection fires → alert generates in SIEM → SOC workflow triggers → response action executes. A detection that fires but doesn't generate a usable alert is not a working detection.

Regression testing after changes

When you upgrade your EDR agent, change a detection policy, add a new system to scope, or modify a SIEM integration, SCYTHE automatically re-runs your validation suite to confirm nothing regressed.

Outcomes

What You'll Know After Running SCYTHE Against Your EDR

Clear, actionable evidence — not a list of assumptions your team has to manually verify.

Coverage map

Which MITRE ATT&CK techniques your EDR detects, and which it misses — visualized against the ATT&CK matrix showing actual coverage density, not vendor-claimed coverage.

False negative rate

What percentage of adversary techniques execute without generating a detection, tracked over time so you can see whether coverage is improving or degrading.

Alert quality

When a detection fires, does it generate a useful, actionable alert — or alert fatigue noise? SCYTHE measures alert fidelity alongside detection rate.

Regression history

A timeline of every detection regression: when it happened, what change preceded it, and whether it has been remediated.

Detection improvement evidence

As your team tunes detection logic, SCYTHE shows the before-and-after — measurable proof that your investment in detection engineering is working.

The Business Case

From Assumed Coverage to Measured Assurance

Continuous validation turns assumptions into evidence. Based on customer-reported outcomes.

Is SCYTHE safe to run against a production EDR?

Yes. SCYTHE is designed specifically for production-safe adversary emulation. Tests are controlled and configurable, all actions are logged and auditable, and destructive capabilities require explicit authorization. SCYTHE is actively used in production environments at Fortune 500 enterprises, financial institutions, and healthcare organizations.

Will SCYTHE cause false positives in our SOC during testing?

SCYTHE integrates with SOAR and ticketing platforms so your SOC can optionally suppress or tag alerts generated during controlled testing periods. You control the test window and scope.

How is this different from running Atomic Red Team or Caldera?

Atomic Red Team and Caldera are open-source tools that require significant manual operation. SCYTHE provides a production-grade platform with automated scheduling, reporting, SIEM/EDR bidirectional integration, multi-stage campaign capabilities, AI-assisted test generation, and managed service options for teams without dedicated red team staff.

How long does it take to see results?

Most organizations begin identifying detection gaps within the first week of deployment. Because SCYTHE runs continuously, the coverage picture improves over time as your team acts on the findings.
