Modernizing Chat Review: Magnet Axiom Cyber's New RSMF Grouping for eDiscovery

Chat and messaging data today is at the center of many internal investigations, HR cases, and eDiscovery workflows.

Whether the source isSlack, Teams, WhatsApp, iMessageor any other modern communication platform, the volume and density of conversations can quickly overwhelm those reviewing the evidence if it is not presented in a clean and structured way.

Now, with an improvement in your export flowRSMF (Relativity Short Message Format), Magnet Axiom Cyberaddresses this challenge.

Introducing RSMF exports in configurable groupings

Axiom Cyber ​​now allows examiners to export RSMF files in standardized time-based segments:1 day, 1 week, 1 month or 1 year.

Instead of generating a single monolithic RSMF file containing months or years of messages, browsers can now createfragments controlled and ready for reviewof conversation history.

This granular export option solves several pain points that private sector teams often experience when delivering chat evidence to review platforms such asRelativityeitherNuix:

  • Better usability for reviewers:Reviewers no longer have to scroll through huge threads to find relevant content. Breaking chats into logical time segments reflects natural communication patterns and reduces browsing fatigue.

  • Better alignment with “unitization” practices in eDiscovery:eDiscovery historically relies on grouping by date to make document sets more manageable. RSMF fragment exports align chat evidence with that same principle, treating conversations as discrete, reviewable “documents.”

  • Focused Privilege and Responsiveness Review:Attorneys can quickly isolate periods associated with key events, custodians, or potential policy violations, without loading irrelevant historical data.

  • More efficient processing and lower hosting costs:Smaller RSMF files can be processed faster and often hosted at a lower cost, helping legal teams control eDiscovery spend.

Why Bundled Chat Exports Matter in Private Sector Investigations

In corporate environments, investigations rarely focus on a single message: they focus oncommunication patterns. Segmenting chat exports allows organizations to analyze these patterns more accurately, map the flow of communication to business events, and better correlate messages with logs, documents, or other system artifacts.

For eDiscovery teams, bundling RSMF exports also reduces the risk ofover-harvesting. Instead of sending an entire multi-year thread to outside counsel, teams can deliver only the periods tied tolitigation holds, claims or compliance triggers. This means a narrower scope, less review effort, and clearer defensibility.

A more defensible and manageable way to deliver chat evidence

By giving Axiom Cyber ​​users the ability to export RSMF in segments byday, week, month or year, Magnet Forensicsis aligning computer forensics workflows with the reality of modern eDiscovery. It is a practical improvement that helps professionalsDFIR, legal teams, HR investigators, and compliance staff to handle chat data with more structure, speed, and confidence.

As message-based communication continues to dominate corporate operations, innovations like these are not just conveniences: they are necessary to keep investigations efficient, defensible, and aligned with legal review standards.
