Mimecast extends governance platform with Claude Enterprise

Mimecast, a global leader in securing humans, data and AI, has extended its Governance, Compliance & Insights (GCI) platform to enterprise AI conversations. The first AI data source Mimecast GCI integrates with is the Claude Compliance API to ingest Claude Enterprise conversation content, bringing AI data into the same unified experience for archiving, eDiscovery, DSARs, supervision and legal hold workflows that organisations already use.

While organisations race to embrace the benefits of integrating AI into their business, the scale of the risk AI brings to compliance is coming into focus. According to IBM’s 2025 Cost of a Data Breach Report, 63% of organisations that experienced an AI-related breach had no governance policy in place. 

With the European Union AI Act’s August 2026 enforcement deadline approaching and the Securities and Exchange Commission elevating AI governance to a top examination priority, the question for regulated enterprises and any business subject to legal or regulatory audits is no longer whether to govern AI, but how quickly they can demonstrate they already do.

With this integration, Mimecast customers can now preserve, search, produce and archive Claude Enterprise conversations, file attachments, projects, and generated artifacts, using the same workflows and legal hold controls they rely on for every other data source. No new interface. No retraining. Just one unified governance experience that now includes enterprise AI.

Mimecast built the integration using the Claude Compliance API, which provides read-only access to Claude Enterprise conversation content. The API enables compliance and security platforms to surface Claude activity alongside the other enterprise applications they already protect, closing a governance gap that has grown alongside AI adoption.

“Employees across every function are now using AI tools to draft documents, analyze data, and make consequential business decisions. These conversations contain business information that organisations have a legal obligation to govern,” said Rob Juncker, Chief Product Officer, Mimecast. “We’ve spent years building the flexible infrastructure to govern email and the expanding collaboration footprint. AI conversations are now happening at the same scale, with the same sensitivity, and most organisations have zero visibility into them. Leveraging this integration enables Mimecast customers to adopt Claude Enterprise at scale with the necessary visibility and controls to unlock the value of Claude.”

The Mimecast GCI Claude Enterprise integration is designed to meet every organisation where they are – whether they’re a growing mid-market business or a global enterprise navigating complex regulatory demands. On day one, GCI customers gain four primary capabilities:

• Legal hold, eDiscovery and DSARs: Preserve content under legal hold, target relevant data quickly, and respond to discovery, internal investigations, and DSARs without needing to send large volumes of data to external third parties. Search and produce Claude Enterprise conversations, file attachments, projects and artifacts alongside emails and collaboration platform data scoped by custodian, date range or keyword, using the same unified interface your teams already rely on.
  
• Sensitive data monitoring and policy monitoring: Surface sensitive content in Claude conversations — PII, account numbers, confidential IP, product codenames – using the same Boolean and natural-language policy engine already deployed across your data estate.
  
• Compliance archiving and preservation: Continuously archive Claude Enterprise conversations and artifacts with tamper-evident retention. Place custodians under hold and preserve data with a single click, covering all connected data sources at once.
  
• Corporate insights across your data estate: Surface patterns across Claude conversations, email, Teams, and Slack simultaneously — flagging sensitive-topic drift, high-risk custodians, and regulated data exposure wherever it lives.
