What if no known indicators are found but the link still seems suspicious?

Trust your instincts. A result of no known indicators means our checks matched nothing, not that the destination is safe. New phishing sites are created constantly and may not appear in any threat database for hours or days. If something feels wrong, do not click.

Free URL Safety Scanner

Check a link for known threat indicators before you click it. ScanTotal combines reputation data, URL heuristics and live probing, then reports what those checks actually found. Completely free, no account required.

What Is a URL Scanner?

A URL scanner checks a web address before you visit it. Instead of clicking a link and hoping for the best, you paste the URL into a scanner first. The scanner checks the address against threat databases, phishing blocklists, and malware registries, then reports what those checks found: known malicious indicators, suspicious characteristics, or nothing matching at all.

ScanTotal's URL scanner checks every link against Google Safe Browsing, the same database that powers Chrome's built-in warnings, along with additional threat intelligence sources. You get results in seconds. The verdict names what we actually found: a confirmed threat, suspicious characteristics, no known indicators, or an incomplete check if one of the engines did not answer. We do not report a link as safe, because no automated check can prove that.

When Should You Scan a URL?

Any time you receive a link you weren't expecting, or from a source you don't fully trust, scan it first. The most common situations:

Links in text messages (SMS): Smishing scams send fake delivery notifications, banking alerts, and prize messages with malicious links. Among the fastest-growing threats targeting mobile users.
Links in emails: Phishing emails impersonate banks, retailers, and government agencies. The link may look legitimate but lead to a credential-stealing fake site.
Links shared on social media: Scammers spread links through Facebook, Instagram DMs, WhatsApp groups, and X. Even links from known contacts can be malicious if their account was compromised.
Shortened URLs: Services like bit.ly and t.co hide the real destination. There's no way to know where a shortened link leads without scanning it first.
Links from unknown senders: Any message from someone you don't recognize containing a link should be treated with caution until verified.

How ScanTotal's URL Scanner Works

ScanTotal uses a proprietary three-engine detection system that goes far beyond simple database lookups. All three engines run simultaneously and their results are combined for a comprehensive verdict.

Engine 1, URL Safety Analysis (Heuristic)

Analyses the URL structure itself for suspicious patterns. Detects raw IP addresses instead of proper domains, non-standard ports, suspicious path keywords commonly used by malware distributors, dangerous file extensions, excessive subdomains, and URL shorteners. Scores every URL on a 0-100 risk scale with colour-coded results.

Engine 2, ScanTotal Active Analysis (Deep Probe)

Proprietary technology that actively probes URLs in real-time. Detects actual file types being served using binary signature analysis, revealing whether a URL secretly serves an executable instead of a web page. Identifies known malware families (Mirai, Sora, Gafgyt, and others), analyses server behaviour and response patterns, detects servers that selectively serve content to download tools like wget, and examines redirect chains for evasion techniques.

Engine 3, Google Safe Browsing

Cross-references against Google's threat database, one of the world's largest repositories of known phishing pages, malware distribution sites, and deceptive content, updated continuously.

Results from all three engines are combined into a single verdict: threats detected, high risk, use caution, no known indicators, or checks incomplete when an engine does not answer. No known indicators means our checks matched nothing; it is not a certification that the destination is safe. You also get a detailed breakdown of every check and what was found.

What Threats Does URL Scanning Detect?

Phishing sites: Fake websites designed to look like real banks, retailers, or social networks, built to steal your login credentials or payment details.
Malware distribution pages: Sites that automatically download malicious software to your device, or trick you into downloading infected files.
Scam pages: Sites running fake competitions, fraudulent investment schemes, romance scams, or tech support scams designed to take your money.
Command and control (C2) servers: Infrastructure used by cybercriminals to manage malware already installed on compromised devices.
Deceptive content: Pages using misleading information or fake security warnings to trick you into taking actions that benefit an attacker.

Tips for Staying Safe From Malicious Links

Always check the sender before clicking any link in a message. If an email claims to be from your bank, visit their official website directly rather than following the link.
Look at the full URL carefully. Legitimate companies use their primary domain (e.g., paypal.com). Be suspicious of extra words, hyphens, or numbers in the domain name.
Treat urgent messages with extra caution. Urgency ("your account will be closed in 24 hours") is the number one psychological tactic used in phishing attacks.
On a computer, hover your mouse over any link before clicking to see where it actually leads.
Enable Google Safe Browsing in your browser settings for automatic protection. Use ScanTotal for an additional manual check on specific links you're unsure about.

Frequently Asked Questions

Is ScanTotal's URL scanner completely free?

Yes, completely free with no registration required. Paste any URL and get instant results at no cost.

Does ScanTotal store the URLs I submit?

No. We analyze your URL and return results immediately. We do not store URLs, build profiles of your activity, or share your data with third parties. Your privacy is protected by design.

Can the scanner check shortened URLs like bit.ly?

Yes. We resolve shortened URLs to their final destination and scan that destination, so you get results for the actual page the link leads to, not just the shortening service.

What if no known indicators are found but I am still suspicious?

Trust your instincts. A result of no known indicators means our checks matched nothing, not that the link is safe. New phishing sites are created constantly and may not appear in any threat database for hours or days. If something feels wrong, urgent language, a slightly off domain, an unexpected sender, do not click.

Can I scan URLs on my mobile device?

Yes. ScanTotal works on all devices. If you receive a suspicious link on your phone, open ScanTotal in your mobile browser, paste the URL, and check it before tapping.

How does ScanTotal detect malware URLs that other scanners miss?

ScanTotal uses a proprietary three-engine detection system. Unlike traditional scanners that only check databases of known threats, our Active Analysis engine probes URLs in real-time to detect what they actually serve, catching zero-day threats that no database has catalogued yet.

What does the URL risk score mean?

The risk score (0-100) combines multiple analysis engines. A higher score indicates more suspicious characteristics. Scores above 50 trigger caution warnings, and our system flags confirmed malware indicators with a Threats Detected alert.
