Cybereinforce Threat Enforcement

Microsoft Defender does not block URLs
on Chrome and Firefox.
Most security teams overlook this.

Cybereinforce closes Defender’s browser enforcement blind spot by applying deterministic, browser-level URL blocking directly inside Chrome and Firefox while using your existing Defender IOC intelligence.

Full URL path enforcement Sentinel-ready telemetry Audit evidence
65–75%

of enterprise employees use Chrome or Firefox as their primary browser. That’s where most phishing, malware delivery, and credential theft happens.

What Defender can’t do

  • ❌ Enforce full HTTPS URL paths on Chrome / Firefox
  • ❌ Inspect URLs hidden by TLS encryption
  • ❌ Reliably enforce when QUIC / Encrypted Client Hello are enabled

What Defender actually sees

  • ✔ SNI / FQDN only (not full URL paths)
  • ✔ Decisions after TCP/TLS handshake completes
  • ✔ Events logged as ConnectionSuccess even when blocked

Expectation vs Reality vs Enforcement

Expectation

  • IOC blocks URLs everywhere
  • HTTPS inspection sees the full path
  • “Blocked” means blocked
  • SOC can investigate confidently
  • Compliance evidence exists

Reality (Defender today)

  • URL paths enforced only in Edge
  • TLS hides paths in Chrome / Firefox
  • Network Protection sees FQDN only
  • Ambiguous ConnectionSuccess events
  • Hard-to-prove enforcement for audits

Cybereinforce

  • Full URL path enforcement in the browser
  • Deterministic block + redirect
  • Automated IOC ingestion from Defender
  • Structured security events
  • Sentinel analytics, workbooks & retention

What Cybereinforce adds

Browser-level URL enforcement

Full URL path blocking inside Chrome and Firefox, independent of TLS visibility.

Automated IOC ingestion

Defender IOC lists are pushed automatically via Logic Apps and APIs.

Deterministic user experience

Clear block page instead of bypassable warnings or silent failures.

Structured security events

Every block, admin action, and anomaly becomes an investigation-ready event.

Customer-owned SIEM storage

Events land in the customer’s Log Analytics workspace for retention and hunting.

Sentinel analytics & workbooks

Prebuilt rules and dashboards for immediate SOC visibility.

How it works (end to end)

Defender IOC Lists │ ▼ Logic App (Customer Tenant) │ ▼ Cybereinforce Enforcement API │ ▼ Browser Extension (Chrome / Firefox) │ ├─ URL Blocked (Deterministic) ├─ User Redirected to Block Page └─ Security Event Generated │ ▼ Azure Log Analytics (CybereinforceCTE_CL) │ ▼ Microsoft Sentinel Analytics & Workbooks

This is Defender’s blind spot. Now it’s visible.

Cybereinforce does not replace Microsoft Defender. It completes it where most users actually browse.

If your SOC relies on IOC-based blocking, but your users rely on Chrome or Firefox, then without browser-level enforcement you are not blocking URLs but you are only blocking domains.
