# Neuroprotect: protected mode


_Protected mode_ is a mode that [Yandex Browser](https://browser.yandex.com/) enables on bank and payment system pages to make electronic payments more secure. In protected mode, Yandex Browser activates [strict verification of certificates](https://browser.yandex.com/help/en/security/safe-mode.md#sertificates). If the certificate is verified, Yandex Browser [disables extensions](https://browser.yandex.com/help/en/security/safe-mode.md#extensions#extensions), and [its interface is modified](https://browser.yandex.com/help/en/security/safe-mode.md#switch-on). Protected mode is part of [Neuroprotect](https://browser.yandex.com/help/en/security/protection.md), which is an integrated security system.

## Check certificates {#sertificates}

In protected mode, Yandex Browser enables strict verification of [HTTPS](https://en.wikipedia.org/wiki/HTTP) certificates. Protected mode is not enabled if:

- There are [problems with a certificate](https://browser.yandex.com/help/en/security/untrusted-sertificates.md#others), for example, a bank certificate is expired, invalid, or not trusted.
- An [unknown certificate](https://browser.yandex.com/help/en/security/untrusted-sertificates.md#unknown) installed to your operating system by a program or the network administrator is used.
- A [certificate installed by a special program](https://browser.yandex.com/help/en/security/untrusted-sertificates.md#antivirus) is used.


{% note alert %}

If protected mode has not been enabled, it is unsafe to make electronic payments and we do not recommend doing this.

{% endnote %}



## Disabling extensions {#extensions}

In the protected mode, Yandex Browser disables all extensions except password managers verified by Yandex. This is to prevent [malicious extensions](https://browser.yandex.com/help/en/security/check-extensions.md#bad-extensions) from stealing or tampering with your payment information.

The extensions are re-enabled when you exit protected mode.


## Enabling the mode {#switch-on}

 Protected mode is enabled by default when payment pages are open. When this happens, the upper panel and [tabs](https://browser.yandex.com/help/en/navigation/about.md) of Yandex Browser turn dark gray, and the name of the mode and the <svg width="20" height="20" viewBox="0 0 20 20" fill="none" xmlns="http://www.w3.org/2000/svg"><title>Безопасный режим</title><g clip-path="url(#svg-liofm7rg__clip0_11780_81773)"><path fill-rule="evenodd" clip-rule="evenodd" d="M10 3.9397L4.73337 6.94923C4.87276 8.95478 5.11628 10.6484 5.62367 12.0834C6.33073 14.0829 7.56938 15.6417 10.0001 16.7619C12.4324 15.6417 13.6706 14.083 14.3772 12.0836C14.8843 10.6487 15.1273 8.955 15.2666 6.94924L10 3.9397ZM16.5625 6.25003C16.4309 8.61807 16.1886 10.7092 15.5558 12.5001C14.6853 14.9633 13.076 16.8585 10 18.1251C6.92572 16.8585 5.31618 14.9633 4.44518 12.5001C3.81192 10.7092 3.56906 8.61807 3.4375 6.25003L10 2.5L16.5625 6.25003Z" fill="#27C55A"/></g><defs><clipPath id="svg-liofm7rg__clip0_11780_81773"><rect width="20" height="20" fill="white"/></clipPath></defs></svg> icon appear in the [SmartBox](*smart-link).
