• Microsoft 365 Business Standard: Available for organisations with 300 users or less. It provides baseline security, but we strongly recommend reviewing your data estate & security technology before moving forward with a Copilot purchase, and alternative information governance controls in place.
  
  
• Microsoft 365 E3 or A3: Includes core security controls. It bundles Office 365 and EMS but does not include Microsoft Defender. We advise you review your data estate & security technology before moving forward with a Copilot purchase, and alternative information governance controls in place.
   
• Office 365 E5: Provides baseline security. It includes a license for the Office 365 suite, without EMS, but with Defender and other security features like identity access and management, information protection, and insider risk management.
   
• Office 365 E3: Offers minimal security. We strongly recommend reviewing the licensing and upgrading to one with more security controls in place. 

Please note that the above licensing recommendations are based on the security features of each license and are not exhaustive. We recommend that you review your organisation’s security needs and consult with a security expert before making a decision.
