  1. Snare Open Source and Enterprise Agents
    Snare recommends upgrading from its Open Source Agents to its Enterprise Agents solution. From Snare’s website:
    We know that there are still plenty of users around the world who lean on our open source agents so we still make them available to download. We would like to reiterate that they have been out of date for years and we highly recommend that you use Snare Enterprise Agents.
