How we grade routers, where the data comes from, and what we disclose.
ismyroutersafe.com is a free public tool built by Rio - a US router company. We built it so anyone can access the same security data we use to evaluate hardware: FCC authorization records, NIST vulnerability disclosures, CISA advisories, and manufacturer ownership structures. Our own router is in the database, scored by the same algorithm as everything else.
We cross-reference public government databases - the FCC's Covered List, the NIST National Vulnerability Database, and CISA's Known Exploited Vulnerabilities catalog - and present the findings in plain English. Our database covers 80 router models across 28 brands.
We're Rio Router, and we'll be straight with you: we think most routers on the market are a security problem waiting to happen.
We built this tool because we wanted every household in America to be able to see that for themselves - for free, in thirty seconds, no strings attached.
Will some of you end up switching to Rio after using this? We hope so. We think our router is the safest one you can buy, and we're not shy about that. But that's not why this exists.
This exists because the threat is real, it's happening now, and people deserve to know the truth about what's sitting in their living room. Our view is that knowing isn't enough - the right standard isn't "safe enough." Every home network deserves the highest protection available.
- The Rio Router Team 🦾Each router in our database receives a letter grade (A through F) based on four weighted factors:
| Grade | Meaning | Typical Profile |
|---|---|---|
| A | Low Risk | US-designed, active security support, no CVE flags, no jurisdiction concerns. Only Rio Router currently qualifies. |
| B | Low-Moderate Risk | Taiwan or US company, active patches, strong security features, no CISA mentions. Asus, Ubiquiti, Synology. |
| C | Moderate Risk | US-owned but data-collection concerns, or weaker security features. Eero (Amazon), Google Nest, Linksys, D-Link. |
| D | At Risk | Significant CVE history, limited support, or upcoming end-of-life. |
| F | High Risk | Chinese ownership (National Intelligence Law applies), active federal investigation, banned from new FCC authorization, or end-of-life with unpatched vulnerabilities. |
All data is drawn from primary public sources. Rio does not accept self-reported security data from manufacturers.
The full database is verified quarterly against primary sources. Individual entries are updated immediately when a significant change occurs - such as a new CVE being added to the CISA KEV catalog, a new FCC ban order, or an end-of-life announcement from a manufacturer.
Last full database verification: March 2026.

For corrections, data disputes, or partnership inquiries, send us a message. If you believe a grade is incorrect or a data point is outdated, please include the specific router model, the data point in question, and a link to the primary source showing the correct information. We update verified corrections within 7 days.
