The algorithm scores this router 81/100 - a solid B. The structural score is near-maximum: Taiwan ownership, active FCC authorization, and ongoing firmware support all check out cleanly. The B instead of A comes from the capabilities side - strong but not complete, with no built-in VPN and no zero-trust device isolation.
- Ownership (Taiwan): Asus is a Taiwanese company - not subject to China's National Intelligence Law. Full ownership points.
- FCC status: Fully authorized, no review pending. Clean regulatory standing. Full FCC points.
- Support: Active - Asus patches faster than most consumer router vendors. Full support points.
- AiProtection (Trend Micro) included free - blocks malware and botnet domains in real time without a subscription
- WPA3, network segmentation, and custom DNS all supported - solid capability floor
- No built-in VPN - requires a third-party service or manual router-level VPN setup
- 2023: CISA advisory named Asus firmware vulnerabilities (CVE-2023-39238) - Asus patched within a reasonable window, faster than most competitors
- Auto-updates are OFF by default - you must enable them manually or patches won't apply
- Authentication flaw - patched promptly: A remote authentication vulnerability was found and patched by Asus in a reasonable timeframe - better than most consumer router vendors.
- Some China assembly - supply chain nuance: Some Asus hardware is assembled in China. As a Taiwan company, Asus is not subject to China's National Intelligence Law.
