You would like the ability to monitor incidents in specific Slack accounts.
The Slack Securlet defaults to show results for all Slack accounts.
For selecting specific Slack accounts to monitor, go to CloudSOC > Securlets > Slack and then click Accounts and chose the account(s) you would like to monitor. The Securlet for Slack page will now only populate logs/events for that account. This will default back to all account on your next session.
