Is the Asus RT-BE58U safe?

Solid, with a few gaps.

It has 1 of the 8 protections we check and gets regular security updates, but it has 1 serious security finding.

Your router passed. Here’s what it still can’t do.
  • Block unknown devices from joining
  • Stay outside China’s legal reach
  • Remove guests when they leave

Rio does all 8 protections we check. $179.99 with code CHECKED20.

The risks

What this means for you

The top 3 risks, most serious first.

  1. Serious

    It’s made abroad, so the FCC’s 2026 foreign-made router rule applies

    The RT-BE58U is manufactured in Taiwan. no US manufacturing exemption is on file, applying the foreign manufacture penalty.

  2. Moderate

    Its software has a long record of security flaws

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

    Do this: Enable automatic firmware updates immediately (Advanced Settings → Administration → Firmware Upgrade)
    Source: CISA Advisory AA23-158A
  3. Minor

    Asus requires manual opt-in for automatic firmware updates

    This is the single most important configuration step on any Asus router.
