A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

What to do
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 nic.cz and not a lookalike like n-ic.cz.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, 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 nic.cz, so it appears legitimate. All 92 antivirus engines we queried report it clean, it ranks among the world's most-visited sites, and the domain is 28.7 years old, registered on October 29, 1997 — established domains are far less likely to be scams. Even so, always double-check the exact address in your browser, because phishing emails routinely spoof real, trusted domains like this one.
- nic.cz passed our automated checks with a trust score of 95/100. No antivirus engines or major blacklists flagged it at the time of the last scan, and its signals line up with an established, legitimate site. Treat any unexpected login prompt or payment request on it with the same caution you would anywhere.
- Yes — and this is worth understanding. Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from nic.cz), and legitimate sites are occasionally compromised on specific pages. A clean verdict means the site itself checks out today; it does not mean every email or link claiming to be from nic.cz is genuine. Always reach the site by typing the address yourself rather than clicking links in unexpected messages.
- No — all 92 antivirus and blocklist engines in our malware network currently report nic.cz as clean. That's a good sign, though antivirus coverage is only one of the many signals we weigh, and brand-new scam sites can appear clean before vendors catch up.
- No — nic.cz is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.
- nic.cz is 28.7 years old, registered on October 29, 1997. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.
- Yes — nic.cz presents a valid TLSv1.3 certificate issued by Let's Encrypt · YE2, valid for another 56 days. Important caveat: SSL only encrypts the connection between you and the site — it does not verify who runs it. Almost all scam sites now have valid SSL too, so a padlock alone never means "safe".
- nic.cz resolves to an IP operated by CZ.NIC, z.s.p.o. in CZ (Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.
- Yes — nic.cz ranks in the global top 100,000 most-visited sites, which means it has substantial real-world traffic. Genuine popularity doesn't automatically make a site safe, but throwaway scam domains almost never reach this level of traffic, so it's a meaningful point in the site's favour.
- This report is a record of the scan run on July 14, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about nic.cz has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
