With a workforce that was becoming more mobile – leaving the office for onsite deployments for customers, client visits and events – we needed to put in place some extra security measures to better protect our corporate data and our users’ identities. 


We set up a project to implement and deploy Microsoft Enterprise Mobility and Security, which added an extra layer of security to our existing deployment of Microsoft 365 and its peripherals. 

What did we implement? 

  • Multi-factor Authentication (MFA) for all users (Microsoft Intune) 
  • Conditional Access Policies (Microsoft Intune) 
  • Mobile Device Management (Microsoft Intune) 
  • Mobile Application Management (Microsoft Intune) 
  • Safe Attachment Policy (M365 Security + Compliance)
  • Safe Links (M365 Security + Compliance) 
  • DomainKeys Identified Mail (DKIM)
  • Data Loss Prevention (DLP) Policy 

As Microsoft 365 leverages Azure Active Directory (AAD) for user identity management, it was the obvious choice to implement Microsoft Intune to add an additional layer of security for users signing into the Microsoft 365 service. It also provides additional control for our IT admins.

All corporate apps now require MFA when logging in, users can’t take screenshots of corporate data on their phones or copy and paste data from corporate apps to non-corporate apps. IT admins can also wipe all corporate data from users’ personal devices remotely if needed.  

M365 Security and Compliance has had a positive impact on the security of emails and preventing user error. Safe Attachment and Safe Links more rigorously scan emails for malicious links and attachments, identifying them before they reach the user. DKIM signatures have been added to our custom domains in Microsoft 365 so recipients know our email messages actually came from legitimate users within our organisation.

Our services team (Cloud Know How) made sure that all users were aware of the changes. They also supported those that wished to continue to access corporate data from their personal devices in getting set up.  


We now have greater control over our users’ accounts which is of high importance due to the greater levels of mobility of our workforce – working from home and travelling to customers when able. There is also less risk associated with user error due to M365 Security and Compliance imposing background checks before data even reaches the user

Implementing the additional layer of security offered by Microsoft Enterprise Security + Mobility has really given us much greater peace of mind. Our teams are more confident when accessing corporate data remotely and feel safer in their email inboxes!
