Good News for SME Law Firms: Enterprise-Grade AI and Data Protection Now Accessible

For years, advanced AI tools and enterprise‑level data protection and security have been out of reach for smaller law firms.


That’s changing. Microsoft has introduced licensing updates that make Microsoft 365 Copilot and Microsoft Purview available to firms with up to 300 users - all on Microsoft 365 Business Premium.


This is a game‑changer for SME law firms wanting to innovate without compromising client confidentiality or compliance.

What’s Changed for firms with up to 300 users?


Until recently, firms needed to buy costly E3/E5 licences to access Microsoft’s most powerful compliance and AI tools. Now, if you’re already on - or upgrade to - a significantly lower-cost Business Premium licence (which includes Purview and Defender for enterprise level governance, compliance, and data protection).  You can then make the most of the growing range of AI applications with potential to radically improve productivity when implemented and rolled out effectively.

You can currently get a  25% promotional discount for a 365 Business Premium AND 365 Copilot Business bundle. Well worth taking!


We recommend Business Premium and Teams Premium alongside Copilot 365 and/or other legal-specific tools with the benefits and potential readily justifying the investment - backed up with an affordable, effective route to enterprise‑grade security and AI governance.  If you are considering AI or looking to upgrade your data management, security and cyber protection, now will be the best time to do it. 


🌟We can help you put these tools in place and work with you on the Strategy, IT Framework, Plans, Policies, Training and Procedures needed to make AI work for you.


What these tools unlock for your firm .. to let you get started:

  • Purview Suite with AI data protection gives you a similar level of data security, compliance, and monitoring as the largest firms - without the complexity or cost. Including tools for data loss prevention (DLP), sensitivity labelling, auditing, and insider risk management.

Why are Purview and these new AI data protection features important for law firms?


As AI becomes part of daily legal work, it’s vital to know exactly where your client data is, how it’s being used, and that nothing confidential is slipping through the cracks. Purview and its new AI-focused protections give you:


  • Visibility: See who is using otherwise untraceable AI tools (like Copilot, ChatGPT and an array of other legal and non-legal tools) and how they interact with your firm’s documents and emails.


  • Control: Set clear boundaries to ensure that sensitive information is only accessed by the right people and never leaves your secure environment.


  • Compliance: Meet SRA, GDPR, and client requirements with automated monitoring and reporting - without extra admin burden.


  • Peace of mind: Know that your firm is protected against accidental data leaks or misuse as you adopt new AI-powered ways of working.


At Carton & Co, we help law firms move from informal AI experimentation to a structured, strategic approach - balancing innovation with risk, and giving your teams the confidence to use AI safely.

  • How to upgrade to Business Premium and activate Purview Suite

  • How to ensure your firm’s policy is practical, not just theoretical
