B
GOOD
The algorithm scores this router 81/100 - a solid B. Asus's mid-range Wi-Fi 6 router delivers the same structural score as the flagship models - because the score reflects ownership, authorization, and support, not hardware specs. AiProtection is included free. The security foundation is identical to Asus's more expensive hardware.
  • Taiwan company (Asus) - not subject to China's National Intelligence Law. Full ownership points.
  • FCC authorized, no review pending. Full FCC points.
  • Active firmware - Asus's update cadence applies equally to mid-range models. Full support points.
  • AiProtection (Trend Micro) free on this model - identical threat protection to flagship Asus routers
  • WPA3, network segmentation, and custom DNS all supported
  • 2023: CISA advisory named Asus firmware vulnerabilities (CVE-2023-39238) - Asus patched within a reasonable window
  • No built-in VPN - third-party service required
  • Auto-updates disabled by default - the single most important change to make on this router
  • Asus router firmware CVE history: Asus routers have had critical vulnerabilities including CVE-2023-38033 and related 9.8-rated flaws. Most are patched quickly - but only if auto-updates are enabled.
  • Auto-updates disabled by default: Asus requires you to manually enable automatic firmware updates. Without this, critical security patches are missed unless you check manually.
  • AiProtection requires Trend Micro cloud: Asus's AiProtection relies on Trend Micro's cloud service. This adds a third-party dependency. Review Trend Micro's privacy policy if data minimization is a concern.

Live Network Check BETA

The report above reflects your router’s model record. This check runs live probes against your current network to detect issues static analysis cannot - DNS hijacking and admin interface exposure.

🔍
DNS HIJACK CHECK
Detects if your DNS has been silently rerouted to intercept your traffic
🌐
WAN EXPOSURE
Tests if your router admin panel is reachable from outside your home

🔒 Security capabilities comparison
We benchmark your router against Rio Router across 8 dimensions so you can see exactly what gaps exist - and what a fully-covered setup looks like.

Zero-Trust Device Admission
Every new device is blocked by default - admin must approve it once, even if it has the right password
Not available
Available
Network Segmentation (VLANs)
Devices on your network are isolated from each other, so a hacked smart TV can't reach your laptop
Partial

Router-Level VPN for All Devices
All traffic - including smart devices that can't run VPN apps - is encrypted before leaving your home
Partial
Available
Domain Allowlisting
Block everything except approved sites; more effective than trying to blacklist billions of harmful URLs
Available
Available
Granular Password Control
Separate passwords per network zone - changing one doesn't affect others
Partial
