AT RISK
Spectrum's DOCSIS 3.1 gateway (modem + router combo). Technicolor hardware with Charter's management. US company, standard ISP limitations. Technicolor has a mixed CVE history - Spectrum patches are the primary security mechanism.
  • Technicolor vulnerability history: Technicolor's product line has had significant vulnerabilities. Spectrum patches these, but response times have varied.
  • Spectrum remote management: Spectrum has remote configuration access to this device.
  • Limited advanced security configuration: ISP gateways don't support VPN, device isolation, or custom DNS filtering by default.

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

Router-Level VPN for All Devices
All traffic - including smart devices that can't run VPN apps - is encrypted before leaving your home
Locked
Available
Domain Allowlisting
Block everything except approved sites; more effective than trying to blacklist billions of harmful URLs

Granular Password Control
Separate passwords per network zone - changing one doesn't affect others
Locked

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 →
📋 What you should do
1
Change Wi-Fi and admin passwords from device label defaults
2
Contact Spectrum if you believe firmware is significantly out of date
3
