Yes, Piwik PRO uses HTTP Strict Transport Security (HSTS) to secure your web traffic. This ensures that your website or app only communicates with Piwik PRO via a secure https:// connection.
You don’t need to set anything up. Piwik PRO automatically uses HSTS and rejects tracking requests sent from insecure http:// connections.
However, keep in mind that some firewalls may block https:// connections. If a visitor accesses your site from behind such a firewall, their session won’t be tracked.
