About this extension
LibraCyber Browser Defender Enterprise (previously Mantra) provides comprehensive protection for your employees by safeguarding against a variety of online threats.
The extension prevents password exposure by alerting you when your professional password is used on third-party websites or for different accounts, reducing the risk of credential theft.
It uses Artificial Intelligence to detect phishing attacks, adding an additional layer of protection for users' credentials and financial data.
It actively monitors and prevents dangerous downloads that could harm your devices, ensuring that only files you consider to be safe are allowed.
It offers protection against unsafe browsing by blocking access to websites flagged as dangerous, thereby protecting data and users from potential cyber threats.
It identifies and blocks harmful browser extensions that could compromise your security.
It also detects ClickFix attacks, in which deceptive web pages silently copy malicious shell commands to the clipboard and try to trick users into pasting them into Run, Terminal or PowerShell.
It includes Data Loss Prevention safeguards that warn users when they paste sensitive information into AI assistants or other monitored web applications, helping prevent accidental data leaks.

How are passwords saved and used?
During the setup process, we will pass the password through a process that generates a fingerprint. This fingerprint will be used to check if the user is typing their professional password on websites that do not correspond to your professional domain and to prompt them about it. We never store the password. We only store the fingerprint locally, in each user's browser storage.
