Chrome 0-days keep landing. Your safest bet is an EDR/XDR with strong exploit mitigation for browsers, real-time telemetry, and rapid response. Here are the 5 platforms we trust for 2025—and how to deploy them for maximum catch rate.
TL;DR — Pair browser exploit mitigations with XDR telemetry and strict policy baselines.
- Kaspersky XDR/EDR: world-class exploit research + protection; strong record on Chrome 0-days.
- Microsoft Defender for Endpoint: built-in Exploit Protection policies for browsers + tight Windows visibility.
- CrowdStrike Falcon: high-fidelity detections, threat intel, rapid rules for emerging 0-days.
- Palo Alto Networks Cortex XDR: granular exploit-prevention modules for browsers & memory corruption.
- Sophos Intercept X: mature exploit technique blocking (Lockdown), great for mixed estates.

Background: Why browser 0-days evade AV
Modern Chrome exploits chain multiple bugs (renderer → broker → sandbox escape) and live in memory. Traditional file-based AV misses this because there’s no classic “malware file” to scan—just JIT’d shellcode, ROP chains, and abused browser APIs. Your controls must include exploit mitigations for the browser process, memory telemetry, and rapid threat-intel coverage when a new CVE drops.
Top 5 EDR/XDR Picks (2025)
1) Kaspersky EDR / XDR
Why we like it: Kaspersky’s research arm (GReAT) regularly finds Chrome 0-days, and that research flows into protections fast. Strong exploit detection plus response tooling makes it a standout for browser threats.
Best for: orgs that want elite exploit telemetry and multi-OS coverage without rebuilding their stack.

2) Microsoft Defender for Endpoint
Why we like it: Native Exploit Protection policies apply mitigations to Chrome/Edge processes and integrate with MDE alerts for triage. Easy to standardize across Windows fleets; good browser hardening baselines.

3) CrowdStrike Falcon (EDR/XDR)
Why we like it: Rapid intel + detections when new exploits appear, strong behavioral analytics, and fast rule content for emerging CVEs. Excellent for fast-moving 0-day cycles.

4) Palo Alto Networks Cortex XDR
Why we like it: Granular exploit-prevention modules (reconnaissance, memory corruption, code-execution) that specifically call out browser exploitation, plus rigorous policy profiles you can tune by risk.

5) Sophos Intercept X
Why we like it: Mature technique-based exploit blocking (e.g., Lockdown) with explicit protections for web browsers and vulnerable apps; good fit for mixed estates and SMB→mid-market.

Deployment Playbook: High-signal policies
- Harden the browser process: Enable exploit mitigations (CFG, DEP, ASLR, ACG) for chrome.exe/msedge.exe via your EDR policy (MDE Exploit Protection, Cortex EPMs, Sophos Safe Browsing).
- Contain the blast radius: Force least-privilege, block unsigned drivers, and disable unneeded extensions; isolate high-risk browsing in a separate profile/VM.
- Telemetry first: Stream endpoint events to your XDR/SIEM; alert on browser crashes spawning shells, LOLBins, or script hosts.
- Patch velocity: Use vendor RSS/API to auto-prioritize Chrome rapid channel updates when a 0-day drops.
Detection Tips & Triage
- Look for chrome.exe spawning cmd.exe/powershell.exe/wscript.exe or suspicious child browsers.
- Correlate crash dumps with network egress to rare domains; watch for JIT spray / ROP-like telemetry where exposed.
- Hunt for token theft & cookie access from non-browser processes post-exploit; rotate sessions quickly.

FAQ
Q: Which setting matters most for Chrome 0-days?
A: Enforce exploit mitigations on browser processes (DEP/ASLR/CFG/ACG) and block suspicious child-process spawns; stream telemetry to XDR.
Q: Can EDR stop an unknown 0-day without a patch?
A: Yes—technique-based exploit blockers (memory corruption, ROP/JOP, shellcode) can interrupt the chain even before a patch ships.
Q: Do I need browser isolation too?
A: For high-risk users, yes. Pair EDR/XDR with isolation or a hardened profile/VM.
