The algorithm scores this router 22/100 - an F. The NVG589 is 2014-era DSL hardware that AT&T stopped actively updating years ago. The F grade is driven by near-zero capability score combined with end-of-support status pulling the structural score down. Clean US ownership is noted - but hardware this old with no updates is unsupported regardless of who made it.
- AT&T is a US company - no Chinese state jurisdiction concerns. Partial ownership credit in the algorithm.
- Decade-old hardware - designed in 2014, when today's threat landscape did not exist
- AT&T no longer actively updates the NVG589 - any vulnerability discovered now will not be patched
- Zero capability score - no WPA3, no network segmentation, no DNS filtering, no modern security features
- Known authentication vulnerability (CVE-2017-14117) - patched at the time, but the patch cycle has since stopped
- Contact AT&T and request a free upgrade to the BGW320 - it scores significantly higher
- End of active support - 2014 hardware: The NVG589 is over a decade old. AT&T no longer issues regular firmware updates for it. Newly discovered vulnerabilities are not likely to be patched.
- Known authentication vulnerabilities: Authentication bypass vulnerabilities were documented in this device. While patched at the time, the patch cadence has since stopped.
- ISP remote management: AT&T has remote management access to this gateway by default.

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.

What you should do
1
Contact AT&T and request a gateway upgrade to current-generation hardware
2
If upgrade is unavailable: change all default credentials and disable remote management where possible
3
Place a separate router behind the gateway for additional security
