For G Suite.
There is an unfamiliar access type: so called Atom feed in G Suite activity.
What is this?
The Activity of the Atom feed is the one recorded when you check new incoming mail on Gmail using the tools such as RSS Reader.
Every time when the HDE Secure Browser uses this feature to check the unread mails on Gmail, the activity of the Atom feed is recorded.
This is the access which appears when the unread Gmail check settings of the HDE secure browser is set [To be notified]. This is not such a fraudulent access.
