Following our earlier blogs on the E5 Security add-on and E5 Compliance add-on for Business Premium, Microsoft has now provided more clarity and insight on how SMBs can take advantage of these protections.
From September 2025, Microsoft 365 Business Premium customers will have access to new subscriptions: Defender Suite and Purview Suite for Business. These are not the old E5 add-ons - they’re entirely new licences designed to deliver enterprise-grade security and compliance in a way that’s simpler, more accessible, and more cost-effective for small and medium-sized businesses.
Whether you’re securing remote teams, protecting sensitive data, or simply want to sleep easier at night, these new add-ons give your business extra layers of security, smarter compliance tools, and automated protections - all integrated into the Microsoft 365 environment you already use.
