About this extension
Browse Safely -Not every link or text is what it appears to be.

BUILT FOR SAFER BROWSING

Whether you're browsing websites, reading emails, researching online, or navigating unfamiliar pages, stay alert to deceptive links and suspicious URLs.
Protect yourself against common link-based deception techniques and make more informed decisions about which links to trust.

URL SPOOFING PROTECTION

Malicious websites use misleading link text, lookalike domains, Unicode characters, and deceptive URLs to trick you into visiting the wrong website.
PhantomGlass helps detect suspicious links before you click, adding an extra layer of security to your everyday browsing.
Designed to identify common URL deception and link-based phishing techniques.

• Link Text Mismatch Detection
Identify links where the displayed text or domain doesn't match the actual destination URL.

• URL Spoofing Detection
Detect potentially deceptive URLs designed to imitate legitimate websites and mislead users.

• Typo-squatting Detection
Identify suspicious domains that resemble popular websites through misspellings, character substitutions, and other lookalike techniques.

• Unicode & Homograph Detection
Flag suspicious use of visually similar Unicode characters that may make a deceptive domain appear legitimate.

• Suspicious Link Identification
Highlight potentially deceptive links directly on webpages, helping you recognize suspicious destinations before interacting with them.

CLIPBOARD SWAP ATTACKS

BLOCK DIRECT IP

WHY PhantomGlass ?

‣ Phishing attacks exploit visual deception not vulnerabilities.
‣ PhantomGlass exposes deceptive links, visibility where links actually lead.
Proactive link detection: Identify suspicious links before clicking.
‣ Works automatically: 0-click scan, detect link deception without requiring click or manually check each URL.
‣ Seamless browsing: No need to copy and paste URLs into external scanners.
Improve your awareness of suspicious links while browsing.

IMPORTANT INFORMATION

‣ This extension evaluates links and their destinations, not the overall safety or content of a website.
‣ It identifies suspicious link characteristics that may indicate deception or phishing. It doesn't guarantee that a link is malicious or safe.
‣ This is a supplementary security tool, not a complete antivirus or phishing protection solution.
‣ Detection isn't guaranteed. Some suspicious links may go undetected, and legitimate links may occasionally be flagged.
Always verify URLs before entering passwords, payment details, or other sensitive information.
