HIGH RISK
TP-Link's premium Wi-Fi 7 mesh. The most expensive TP-Link mesh system - and the same Chinese government legal jurisdiction applies regardless of price or specs.
  • Federal investigation - applies across all TP-Link: The DOJ investigation is about ownership structure and legal jurisdiction, not any individual product's specs or price point.
  • Investment risk - forced sale or ban possible: A premium Wi-Fi 7 system represents a significant investment. The ongoing investigation creates material risk of forced sale or ban affecting future support and firmware updates.

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

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
Available
Router-Level VPN for All Devices
All traffic - including smart devices that can't run VPN apps - is encrypted before leaving your home
Not available
Available
Domain Allowlisting
Block everything except approved sites; more effective than trying to blacklist billions of harmful URLs
Not available
Available
Granular Password Control
Separate passwords per network zone - changing one doesn't affect others
Partial
Available
Guest Auto-Expiry
Guest devices are automatically removed when they leave; neighbors can't reconnect without re-approval
Not available

Active Threat Monitoring
DNS filtering, firewall, activity logs, and ongoing security patch support

We use Rio Router as the benchmark because it’s the only consumer router built to score 8/8 on this framework - it shows you what a fully-covered setup looks like, not just what’s typical. See Rio →
