Our automated security review found no threat indicators on cwi.nl. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.

Is cwi.nl safe to use?

cwi.nl passed our automated security checks with a trust score of 95/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.

Does cwi.nl have a valid SSL certificate?

Yes. cwi.nl presents a valid TLSv1.3 certificate issued by Hellenic Academic and Research Institutions CA · GEANT TLS ECC 1, expiring in 150 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.

How old is the cwi.nl domain?

cwi.nl is 40.2 years old, registered on 4/30/1986 through SURF B.V.. Scam domains are often freshly registered — a site under 6 months old warrants extra caution.

Has cwi.nl been flagged by antivirus engines?

No. All 92 antivirus engines in our malware network report cwi.nl as clean.

Is cwi.nl on any phishing or malware blacklists?

No. cwi.nl is not currently listed on the major browser blocklist feeds that modern browsers use.

Where is cwi.nl hosted?

cwi.nl resolves to an IP operated by CWI Amsterdam The Netherlands in NL (usage type: Commercial). 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.

How often is the cwi.nl report updated?

This is a permanent record of the scan run on July 10, 2026. The verdict and evidence above reflect that scan and do not change on their own. If circumstances around cwi.nl have changed, MalwareTips staff can run a fresh scan, which re-runs every check from scratch and publishes an updated report.

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 cwi.nl and not a lookalike like c-wi.nl.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.
