EDR and AV Effectiveness Testing
Validate whether your endpoint protection tools block, detect, or miss real-world attack behaviours — across EDR, AV, EPP, and XDR platforms.
The Valitrix endpoint module safely simulates real attacker techniques against your live EDR, AV, EPP, and XDR — then shows which ones were blocked, detected, logged, or missed. For the discipline itself, see the Endpoint Security Validation guide.

This page vs the validation guide
This is the product page — how Valitrix tests your live EDR, AV, EPP, and XDR. The Endpoint Security Validation guide explains the discipline: what the practice is, why it differs from a pentest, and how to measure endpoint control coverage. Use the guide to learn; use this page to evaluate the module.
The Valitrix endpoint module…
The Valitrix endpoint module tests live EDR, AV, EPP, and XDR by executing controlled adversary techniques on approved endpoints and recording whether each one was blocked, detected, logged, or missed.
Valitrix EPSV validates endpoint defences by safely simulating attacker techniques such as script execution, credential access, privilege escalation, persistence, defense evasion, ransomware behaviour, and data staging. The result is evidence-based visibility into what your endpoint tools stop, what they detect, and what they miss.
Unlike a static configuration audit, EPSV triggers actual control responses — so you see real prevention and detection rates, not assumed ones. Every result is mapped to a MITRE ATT&CK technique, giving security teams a shared language for gaps, risk, and remediation priority.
Valitrix EPSV helps by…
Running controlled, MITRE ATT&CK-mapped simulations on approved endpoints and measuring whether each attack was blocked, detected, logged, or missed — then surfacing actionable remediation for every gap.
Security teams use EPSV to…
Continuously prove the real effectiveness of EDR, AV, EPP, XDR, and SIEM controls between red team engagements — and to validate improvements after policy changes, tuning exercises, or tooling updates.
The main outputs are…
A per-technique detection and prevention scorecard, ATT&CK coverage heatmap, missed-detection list with remediation guidance, SIEM visibility assessment, and executive-ready risk reporting.
Endpoints remain a primary initial foothold for attackers. Yet the effectiveness of EDR, AV, and EPP tools depends on correct policy configuration, telemetry tuning, and operational response workflows — none of which can be assumed.
Exclusions, policy exceptions, and default configurations routinely create blind spots that go undetected until an attacker exploits them.
Weak SIEM correlation and noisy EDR alerts cause security teams to miss genuine detections buried in high-volume alert queues.
Vendors test against their own benchmarks. EPSV tests against your actual environment, your configuration, and your telemetry pipeline.
Policy updates, software rollouts, and exclusion changes silently degrade detection coverage. Continuous validation catches drift before attackers do.
Endpoint Security Validation (EPSV) covers the full breadth of real-world endpoint attack techniques — from initial access and credential access through to defense evasion and exfiltration.
Validate whether your endpoint protection tools block, detect, or miss real-world attack behaviours — across EDR, AV, EPP, and XDR platforms.
Every simulation maps to a specific ATT&CK tactic and technique, giving you a measurable coverage picture against the industry-standard adversary framework.
Safely test encryption activity patterns, process injection, payload staging, and persistence behaviour without executing real malware in your environment.
Validate detection of PowerShell abuse, WMI, LOLBins, obfuscated scripts, and command-line interpreter abuse — the techniques that most often evade signature-based controls.
Assess whether endpoint controls detect LSASS access attempts, token manipulation, UAC bypass behaviour, and privilege escalation paths from standard user to system.
Confirm that endpoint telemetry reaches the SIEM, correlation rules trigger, and meaningful alerts are generated — not just that the endpoint tool ran.
Measure whether your controls detect AMSI bypass, process injection, timestomping, and other evasion techniques used to disable or blind security tooling.
Convert every missed detection into a prioritised tuning action — including hardening steps, detection logic recommendations, and remediation evidence for retesting.
Choose from a library of MITRE ATT&CK-mapped endpoint attack scenarios or run a full kill-chain campaign across your approved test endpoints.
Valitrix agents execute inert, scope-approved simulations — triggering real control responses without causing data loss or system disruption.
Each simulation records whether the behaviour was blocked, detected, logged only, or missed — and whether the event reached your SIEM and generated an alert.
Results are automatically tagged by ATT&CK tactic, technique ID, and risk severity — giving you a coverage heatmap and gap summary your team can act on.
Valitrix surfaces actionable remediation guidance for each gap. Retest the same techniques after tuning to confirm your controls have improved.
An 8-stage APT kill chain executed against a live endpoint. Each stage maps to a MITRE ATT&CK technique and shows a real detection outcome — blocked, detected, or missed.

Endpoint Security Validation (EPSV) produces concrete, evidence-backed outputs that security teams can use for remediation prioritisation, executive reporting, and compliance evidence — not just a list of vulnerabilities.
EPSV does not only show whether an attack ran. It shows whether your endpoint control blocked it, detected it, logged it, and created useful investigation evidence — and maps each outcome to the MITRE ATT&CK technique that was simulated.

Results are mapped to MITRE ATT&CK technique IDs, providing a common framework for communicating gaps to detection engineers, SOC teams, and executive stakeholders.
Confirm your EDR configuration, policies, and telemetry are working before wider deployment.
Re-validate detection coverage whenever EDR policies, exclusions, or SIEM rules are modified.
Run safe ransomware-behaviour simulations to confirm your controls detect encryption activity and persistence mechanisms.
Provide detection engineers with repeatable, evidence-backed validation of EDR and SIEM rule improvements.
Generate ATT&CK-mapped, time-stamped validation evidence for compliance requirements and board-level cyber resilience reporting.
Confirm that endpoint events are correctly ingested, normalised, correlated, and generating actionable alerts downstream.
Evidence-based control effectiveness, risk reduction measurement, and executive-ready reporting that replaces assumptions with proof.
Reduce missed detections, improve alert quality, and validate that analyst investigation workflows receive useful telemetry and context.
Tune EDR and SIEM detection logic, validate Sigma-style rule improvements, and confirm coverage gaps are closed after remediation.
Validate endpoint architecture, hardening baseline, and telemetry design against real adversary behaviour before and after major changes.
Generate repeatable validation evidence mapped to security controls and ATT&CK for frameworks, audits, and cyber resilience programmes.
Valitrix EPSV is designed to run controlled, authorised simulations against scope-approved endpoints only. All simulated payloads are inert and designed to minimise disruption — triggering security controls without causing data loss, system instability, or service interruption. Simulations must follow your organisation's approved testing scope, change management window, and endpoint allowlisting or exclusion process before execution.
Valitrix does not execute real malware. The distinction between safe behaviour simulation and destructive malware execution is a core principle of the platform.
Every simulation result in Valitrix EPSV is tagged with a MITRE ATT&CK technique ID. When your EDR or SIEM misses a technique, the result is not just a red flag — it is a specific, mapped gap that your detection engineers can act on directly.
EPSV surfaces remediation guidance alongside each missed detection: hardening steps, detection logic recommendations, and the expected control response — so teams know exactly what to tune, not just that something is wrong.

Illustrative sample — results depend on your endpoint configuration, EDR policy, and SIEM correlation rules.
Every result is backed by simulation evidence — not assumed coverage scores. You see exactly what was blocked, detected, and missed.
EPSV is not a one-time test. Run campaigns continuously, retest after tuning, and track control drift over time across your environment.
Endpoint, email, network, and SIEM validation work together in Valitrix — so you see how endpoint gaps interact with the rest of your security stack.
Prevention ratio, detection coverage, SIEM visibility, and ATT&CK coverage are all measurable outputs — not qualitative summaries.
Generate executive-ready risk reports and granular technical remediation guidance from the same validation run.
MITRE ATT&CK alignment means every gap you fix is a technique an adversary can no longer exploit silently in your environment.
Endpoint detections feed your SIEM and sit alongside email and network controls. Valitrix validates the full security stack — not just individual tools.
Run a guided Valitrix EPSV demo and see how endpoint simulations expose missed detections, weak prevention rules, and SIEM visibility gaps — before attackers exploit them.
