Non-Marketo User Able To View Entire Contact Record

Hello! 

I am just starting to create report subscriptions for my sales team. I love the Company Web Activity Report, which displays Person, Company (or inferred company), location, pageviews etc. 

In the report email, upon clicking either the name or the pageview links, the user is able to open up the entire contact record and view all of the tabs (even if they're not a registered Marketo user in our instance).

They can view, not edit, but I am wondering if there is a way to lock down certain tabs or have only the "Activity Log" section available? 

Thank you !
