About Signum — Website Trust Check
**Is this site safe — or are you about to get scammed?**
Signum scans any website you're visiting and gives you an instant AI-powered trust verdict. Powered by 15 threat intelligence sources, it tells you if a site is legitimate, suspicious, or a scam — in plain English.
**Why Signum?**
In 2024, people lost $12.5 billion to online scams. That's up 25% in a single year. Fake shops, phishing pages, and crypto fraud sites now look identical to legitimate websites. The padlock in your browser means nothing — it only confirms your connection is encrypted, not that the site is safe.
Signum checks the signals that actually matter:
→ Domain age and registration history
→ SSL certificate validity and issuer trust level
→ IP neighbourhood — is the site hosted alongside known scam sites?
→ VirusTotal and 14 other threat databases
→ Brand impersonation detection via AI visual analysis
→ Certificate transparency logs
→ WHOIS and DNS anomalies
→ Social media presence verification
→ Payment page detection (crypto, suspicious checkout flows)
**How it works**
1. Click the Signum icon while browsing any website
2. Press "Check this site"
3. Get an instant risk score (0-100), verdict, and plain-English explanation of every red flag found
No technical knowledge required. Built for anyone who shops online, transfers money, or clicks links from emails.
**What you'll see**
• Risk score from 0-100
• Verdict: Likely Safe / Suspicious / Danger
• Warning banner for high-risk sites
• Key findings explaining exactly what's wrong
• One-click access to the full detailed report
**Who uses Signum**
→ Online shoppers verifying new stores before paying
→ Business owners vetting suppliers and vendors
→ Anyone who received a suspicious link by email or message
→ IT teams checking domains reported by employees
→ Parents protecting family members from scams
**Free to use. No account required.**
Signum is free for basic scans. No personal data collected, no browsing history stored. We only scan the domain you explicitly request — nothing happens automatically.
