  2. 2.
    Had the relevant log shipping endpoints & credentials shared via the Netacea portal.
  3. 3.
    Provided a list of all known, safe and trusted list users, partners & 3rd party apps. This includes a list of trusted bots & automated tools. Any information on known bad actors is also valuable.
  4. 4.
    Provided a list of protection use cases and the pathways that are vulnerable to each.
