Thank you for posting in the Community, @isocertifier.

Yes, information security is implemented for data transfer to ensure that data is protected from unauthorized access, tampering, and interception.

For more information, I suggest reaching out directly to Hubspot support. Since QuickBooks Online only receives data from HubSpot, you can find the HubSpot support page in the QBO App Store.

Comment below if you require further assistance with information security. I'll be here to lend a hand.
