Proofpoint acquires Nuclei to boost AI workplace compliance tools

Proofpoint has acquired Nuclei, a technology company specialising in compliance archiving and AI-driven data enrichment for workplace communications.

The acquisition will see Proofpoint extend its digital communications governance offering with additional capabilities to capture, retain, and analyse communications data across collaboration platforms such as Microsoft Teams, Slack, Zoom, Webex, WhatsApp, and RingCentral Voice.

Proofpoint has outlined that it will continue to support integration with a broad range of archive and data governance platforms, ensuring its connectors can deliver compliant interoperability for a wide variety of customer environments.

Harry Labana, Senior Vice President and General Manager of Proofpoint's DCG Business Unit, said: "This acquisition enables us to accelerate our mission to deliver the most advanced and comprehensive AI-powered digital communications compliance platform in the market today, and we are excited to welcome Nuclei's talented team to Proofpoint.

"By combining Proofpoint's leading human-centric security platform with Nuclei's pioneering technology, we can provide our customers with enhanced regulatory compliance while unlocking valuable insights from conversational data, which will be a game changer, particularly for highly regulated industries."

The Nuclei platform offers several features for organisations, including the ability to capture and archive data from more than 100 applications. It can automatically collect messages, attachments, and metadata from a wide range of collaboration tools.

AI transformation tools available through Nuclei include speech recognition in over 120 languages, real-time transcription, automatic translation, and video analysis. These functions are intended to help organisations derive actionable insights from their communication data.

The platform is also designed for seamless integration with several major compliance archives, including Proofpoint, Smarsh, Global Relay, Arctera, and Microsoft Purview, to support organisations in meeting regulatory requirements.

Nuclei's infrastructure is built on a serverless architecture on Amazon Web Services. It incorporates real-time compliance and security measures such as third-party audits by firms like Vanta, as well as end-to-end encryption that protects data in transit and at rest from capture through to storage.

The value of human communication as a source of insight, process automation, and risk identification is a key area that Nuclei seeks to address by enabling capture, archiving, and analysis of communications data for intelligence extraction and compliance assurance.

Eric Franzen, Chief Executive Officer of Nuclei, said: "At Nuclei, our mission is to democratise access to the world's most valuable data by transforming workplace communications into structured, compliant, and actionable information.

"This vision has fuelled our innovation from the start. Partnering with Proofpoint allows us to extend that impact by helping the world's largest organisations boost productivity across hundreds of collaboration platforms while staying ahead of growing regulatory requirements."

Proofpoint holds the status of a Leader in the 2025 Gartner Magic Quadrant for Digital Communications Governance and Archiving Solutions, based on completeness of vision and ability to execute.
