B
BETTER THAN MOST
The Verdict

This is one of the better routers on the market - and it still has gaps that matter. The RT-BE58U is manufactured in Taiwan. Without router-level VPN or strict network segmentation, your work laptop, banking sessions, security cameras, and any infected smart device all share the same flat network.

A B grade is a relative ranking in a market where the floor is low. The gaps are real, they just aren’t urgent.

  • Your home network is more exposed than it should be

    Your home network is more exposed than it should be. Your work laptop, banking sessions, security cameras, and smart home devices all pass through this router - a flaw here gives an attacker leverage over all of them at once.

    Foreign manufacture - Taiwan, no US exemption: The RT-BE58U is manufactured in Taiwan. Under the current scoring rubric, no US manufacturing exemption is on file, applying the foreign manufacture penalty.

  • A real gap that affects every device sharing this Wi-Fi

    It affects every device sharing this Wi-Fi - your work laptop, your phone, your kids' devices, your security cameras. Not the most urgent threat on the page, but a real edge an attacker can use to reach the rest.

    Show technical detail

    Asus CVE history - patched but notable: Asus routers have had critical vulnerabilities including CVE-2023-38033. Most are patched quickly - but only if auto-updates are enabled.

  • A small gap that still touches every device on this network

    A small gap, not an urgent one - but it still touches everything on this network: your work laptop, your phone, your security cameras, and any guest device that joins the Wi-Fi.

    Show technical detail

    Auto-updates disabled by default: Asus requires manual opt-in for automatic firmware updates. This is the single most important configuration step on any Asus router.

full standard
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

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
