  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Riot Android

    Riot Android

    A glossy Matrix collaboration client for Android

    Riot Android is the original Android client for the Matrix network — a decentralized, secure communication protocol — that enables users to send end-to-end encrypted messages, join rooms, conduct voice and video calls, and interact across federated communities without relying on centralized servers. As the predecessor to Element X, Riot Android laid the groundwork for mobile access to Matrix while providing advanced features like threaded replies, rich media handling, room moderation, and custom notification controls. It integrates tightly with Android’s native platform capabilities, offering background sync, push notifications, and account management while keeping user cryptographic keys secure on the device for privacy. Users appreciate Riot’s ability to join public or private communities hosted across different Matrix servers, making it useful for both personal and organizational communication with interoperability at its core.
