Your EDR vendor says their product catches 99% of threats. Privilege Zero finds out what that other 1% looks like in your specific environment — and whether it's the 1% that matters.
Endpoint controls are only as good as their configuration. Default exclusion paths created during installation. Overly broad application whitelist rules. DLP policies that miss common exfiltration techniques. An EDR policy that was tuned to reduce alert noise but went too far. Privilege Zero tests your actual deployed controls — not a reference implementation — to produce a detection coverage percentage that reflects reality.
We execute structured bypass techniques against your live endpoint environment and correlate the results against alert telemetry. Every technique either fires an alert or it doesn't. The output is an evidence-based coverage metric — not a vendor benchmark score.
Behavioural detection, process injection, API hooking, memory scanning
Typical gap: 35% undetected
Signature, heuristic, and ML-based file detection
Bypassed by most obfuscation
Data classification, channel monitoring, exfil prevention
Significant channel gaps common
Execution whitelisting, LOLBin blocking, script control
LOLBin gaps most common
Enumerate all deployed endpoint agents, version levels, policy configurations, exclusion lists, and tamper protection settings. Identify policy gaps before active testing begins.
Verify that agents cannot be disabled or uninstalled by a local admin, standard user, or malicious process — testing the tamper resistance that prevents an attacker from simply turning off your controls before proceeding.
Execute a structured series of EDR bypass techniques: AMSI bypass, ETW patching, API unhooking, process injection variants, reflective DLL loading, and signed binary proxy execution — recording alert status for each.
Deploy benign malware simulation artefacts replicating real malware behaviour patterns — testing both signature-based and behavioural detection logic with obfuscated and non-obfuscated variants.
Test DLP rules against real exfiltration channel techniques and application control policies against LOLBin execution, script obfuscation, and application whitelist bypass methods.
Correlate all tested techniques against alert telemetry to produce per-control detection percentages. Deliver vendor-specific policy configuration changes — not generic recommendations — for each identified gap.
Detection rate heatmap per control category — showing exactly which bypass technique classes evade each deployed control.
Documented proof-of-concept for every successful bypass — with logs confirming the absence of alerts for each tested technique.
Vendor-specific configuration changes for your EDR/AV/DLP platform — tested against your environment, not generic vendor hardening guides.
Complimentary retest of all critical bypasses after policy changes are applied — confirming the improvements actually closed the gaps.
We test against your deployed configuration, in your environment. Not a benchmark. Not a demo. Your actual controls, your actual gaps.
