The Client
TLT is a UK law firm operating across local, national and international markets. Working within a highly regulated environment, the firm manages large volumes of sensitive and confidential client information across legal and business operations, making strong governance and security controls essential.
The Challenge
As interest in AI tools continued to grow across the business, TLT wanted to introduce Microsoft Copilot in a secure and controlled way that aligned with legal confidentiality requirements and governance obligations.
Because Copilot operates within existing Microsoft 365 environments, the firm needed confidence that data access, permissions and governance controls were operating consistently and that sensitive information would remain appropriately protected.
Key challenges:
- Ensuring AI adoption aligned with legal confidentiality requirements.
- Strengthening governance around sensitive and client data.
- Improving visibility into data access and sharing practices.
- Applying identity and access controls consistently across Microsoft 365.
The Solution
CWSI worked closely with TLT and Microsoft to assess the organisation’s Microsoft 365 environment and strengthen the governance and security controls needed to support secure AI adoption.
Through a structured assessment, CWSI helped identify areas where governance controls could be strengthened while ensuring the environment remained practical for day-to-day use.
Solution Components:
- Microsoft 365 readiness assessment for Microsoft Copilot.
- Review of identity, access and governance controls.
- Refinement of sensitivity labelling and data classification controls.
- Ongoing collaboration to support secure long-term AI adoption.
The Result
The engagement delivered a stronger governance and security foundation for Microsoft Copilot adoption, helping TLT move forward with confidence while maintaining appropriate protection around sensitive and client information.
By improving visibility and aligning governance controls more consistently across Microsoft 365, TLT established a scalable foundation for future AI initiatives.
Key Outcomes
- Secure foundation established for Microsoft Copilot adoption.
- Stronger alignment between identity controls and governance policies.
- Increased confidence in protecting sensitive and client information.
