Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on caniuse.com and not a lookalike like c-aniuse.com.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

Safety FAQ
Common questions about this site, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- Our automated security review found no threat indicators on caniuse.com. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.
- caniuse.com passed our automated security checks with a trust score of 93/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.
- Yes. caniuse.com presents a valid TLSv1.3 certificate issued by Let's Encrypt · R13, expiring in 59 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.
- caniuse.com is 16.2 years old, registered on 4/27/2010 through Tucows Domains Inc.. Scam domains are often freshly registered — a site under 6 months old warrants extra caution.
- No. All 92 antivirus engines in our malware network report caniuse.com as clean.
- No. caniuse.com is not currently listed on the major browser blocklist feeds that modern browsers use.
- caniuse.com resolves to an IP operated by InMotion Hosting, Inc. in US (usage type: Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad, but unusual geography for a brand's claimed country is one of many signals we weigh.
- This is a permanent record of the scan run on June 19, 2026. The verdict and evidence above reflect that scan and do not change on their own. If circumstances around caniuse.com have changed, MalwareTips staff can run a fresh scan, which re-runs every check from scratch and publishes an updated report.
