To protect confidential data that you enter on websites of banks and payment systems (such as bank card numbers and passwords for online banking), as well as to prevent funds from being stolen when you make online payments, Kaspersky Security Cloud prompts you to open such websites in Protected Browser.

Protected Browser is a special browser operating mode designed to protect your data as you access bank or payment system websites. Protected Browser is started in an isolated environment to prevent other applications from injecting their code into the process of Protected Browser. Kaspersky Security Cloud creates special profiles for the Mozilla Firefox and Google Chrome browsers to prevent third-party add-ons from affecting the operation of Protected Browser. The application does not affect your data that the browsers may save in the profiles created for them.

If you are using Chromium-based Microsoft Edge, Google Chrome, Mozilla Firefox, or Internet Explorer, Protected Browser is opened in a new window.

The application uses the Kaspersky Protection extension to provide a number of Protected Browser functions.

Browsers that do not meet the software requirements cannot operate in Protected Browser mode. Instead of such browsers, either Chromium-based Microsoft Edge or another browser configured in application settings starts in Protected Browser mode.

It is impossible to run Protected Browser under the following conditions:

  • check box is cleared in the Enable Self-Defense subsection of the General section of the application settings window;
  • Javascript is disabled in the browser.

Running Protected Browser in Yandex Browser

Kaspersky Security Cloud supports securing your financial transactions in Yandex Browser with some limitations. To run Protected Browser, the application injects a special script into the web page (and traffic). The Kaspersky Protection extension is not available. The Private Browsing and Anti-Banner components operate but cannot be configured in Yandex Browser.

Protected Browser capabilities

In Protected Browser mode, the application provides protection against the following types of threats:

  • Untrusted modules. The application runs a check for untrusted modules every time you visit a bank or payment system website.
  • Rootkits. The application scans for rootkits at Protected Browser startup.
  • Invalid certificates of bank or payment system websites. The application checks certificates when you visit a bank or payment system website. The check is performed against a database of compromised certificates.

Protected Browser status

When you open a website in Protected Browser, a frame appears on the borders of the browser window. The color of the frame indicates the protection status.

The frame of the browser window can display the following color indications:

  • Green frame. Signifies that all checks have been performed successfully. You can continue using Protected Browser.
  • Yellow frame. Signifies that checks have revealed security problems that need to be resolved.

    The application can detect the following threats and security problems:

    • Untrusted module. Computer scanning and disinfection is required.
    • Rootkit. Computer scanning and disinfection is required.
    • Invalid certificate of a bank or payment system website.

    If you do not eliminate the threats detected, the security of the bank or payment system website connection session is not guaranteed. Events involving the launch and use of Protected Browser with reduced protection are recorded in the Windows event log.

About protection against screenshots

To protect your data when you browse protected websites, Kaspersky Security Cloud prevents spyware from taking unauthorized screenshots. Protection against screenshots is enabled by default. Protection against screenshots is running even if hardware virtualization is disabled.

About clipboard data protection

Kaspersky Security Cloud blocks unauthorized access by applications to the clipboard when you make online payments, thus preventing theft of data by criminals. Such blocking is active only if an untrusted application attempts to obtain unauthorized access to your clipboard. If you copy data manually from the window of an application to another application's window (for example, from Notepad to a text editor window), access to clipboard is allowed.

Clipboard protection is not running if hardware virtualization is disabled on your computer.

If Protected Browser is started under the Microsoft Windows 10 operating system, Kaspersky Security Cloud will block interaction of Universal Windows applications with the clipboard.
