If you have already registered, login here and click the ET Open menu to get access. There is no charge and no credit card information required.
Coming benefits of using a code to download your rulesets will include in the near future – being able to see logs of which of your sensors have pulled which platform, and alerts when a sensor does not update within a defined period.
Coming soon we’ll also have a ruleset manager and load rating system to allow you to manage load and choose rules based on quantified performance!
