When you first begin using Securly you would need to integrate your G Suite OUs with the Securly UI. This is essential to map the filtering policies to the correct OUs.
G Suite to Securly integration is a one-time process and all subsequent user updates to your G Suite OUs are dynamically updated to Securly. Only when you delete any OU in G Suite do you need to do a manual import. To learn how the G Suite to Securly OU import works, click here.
