SSL certificate

Updated: 30.10.2026Reading time: 1 minute

An SSL certificate (strictly speaking, a TLS certificate) confirms that a website belongs to its domain and lets the browser open an encrypted HTTPS connection. Without one, browsers show “Not secure”.

A certificate protects data in transit between visitors and the server: forms, sign-ins and payments. It does not make the website’s own code secure — that takes updates and protection.

We choose the right certificate, install it, redirect to HTTPS and check the chain. PositiveSSL starts at RUB 5,800 per year.

Critical severityTwo vulnerabilities in the PHP core. Fixes are already available.

Protect your website: update PHP

Under certain conditions, an attacker can execute code on the server without a login or password. The website, passwords, keys and any other data the PHP process can access are at risk.

Fixed releases:

Leave the update to specialists

We’ll check your website and server, update PHP, the CMS and extensions with compatibility in mind, and fix any other vulnerabilities we find.

Technical details

Install the fixed release of your branch or your OS vendor’s patched package; there is no need to move to 8.4 specifically. PHP 8.1 and earlier have no official fixes — check for a vendor patch or plan a move to a supported branch.

Updating the CMS alone is not enough: PHP itself must be fixed on the server. Before updating, make a backup and check compatibility; afterwards, restart the PHP services (PHP-FPM, web server) and test your websites.
