Buckle Down on Data Protection
Ensuring the right data controls are in place is usually a major part of any conversation about Microsoft 365 security, Hevesi says of his calls with customers.
'Data protection is probably the biggest trend,' he notes. 'How do I protect my data, how do I know where it's going, is it secured, making sure sensitive data is encrypted when it leaves.'
Many businesses inadvertently leave data vulnerable when they turn on Teams, email, SharePoint, and other applications without turning on data loss prevention (DLP), Hevesi says. 
'A lot of organizations are opening things up now, especially as we're working from home,' he says. Employees may be using personal devices to access corporate resources; as a result, they may need access to Microsoft applications from laptops or desktops that lack protections.
But when left permissive, these apps open the door for employees to create a new team, share information externally, or take other risky actions. Once shared data starts to circulate, IT and security teams then have to scan what's out there to see if they can lock it down.
He advises practitioners to enable stricter permissions early on, so they have time to properly configure DLP and educate employees on security practices. These restrictions can then be lifted when tools are in place, features are turned on, and employees know how to use them.
'We say start with locked down external sharing until you get the DLP and the data classification and data monitoring of the CASB (cloud access security broker) in place, and then train employees on how to do this properly,' he explains. It's safer to be more restrictive while employees are being trained, then open up permissions so they can meet business needs.
