    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 — and even commodity malware — 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 coverage map — not their actual 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.

    WHY GAPS EXIST

    EDR validation is continuous, evidence-based, not assumed.

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

     

    Does my EDR detect this specific technique against this specific target system? Does the detection generate an alert in my SIEM? Does the alert trigger the correct SOC workflow? Did a recent change break a detection that was previously working?

    THE SOLUTION

    How SCYTHE Validates Your EDR

    Four validation pillars, running continuously in your live environment, not in staging.

    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.

    SUPPORTED PLATFORMS

    Validated against the platforms your team actually runs.

    Bidirectional integrations with the most widely deployed enterprise EDR and SIEM platforms.

    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.

    COMMON QUESTIONS

    Frequently asked questions

    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.
