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 isc.org and not a lookalike like i-sc.org.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.
- OpenDiscuss this site on the forum

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 isc.org. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.
- isc.org passed our automated security checks with a trust score of 97/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.
- Yes. isc.org presents a valid TLSv1.2 certificate issued by GlobalSign nv-sa · GlobalSign Atlas R3 DV TLS CA 2025 Q4, expiring in 167 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.
- isc.org is 32.2 years old, registered on 4/4/1994 through Tucows Domains Inc.. Scam domains are often freshly registered — a site under 6 months old warrants extra caution.

- No. isc.org is not currently listed on the major browser blocklist feeds that modern browsers use.
- isc.org resolves to an IP operated by Fastly, Inc. in US (usage type: Content Delivery Network). 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.
- Yes. isc.org sits in the global top-100k on Cloudflare Radar, which means it has substantial real-world traffic. That does not automatically make it safe, but established brands almost always rank here and throwaway scam domains almost never do.
