Ostentus review
A focused, auditable presentation workflow for RelativityOne-centered litigation teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ostentus is Delium’s evidence-presentation product for legal teams working in RelativityOne. It supports depositions, trials and arbitrations by helping litigators prepare and sequence evidence, present documents and pages, and maintain records of hearing activity. The product is suited to teams that want controlled presentation workflows within the RelativityOne environment, particularly when presentation accuracy and an auditable event history matter.
Preparation and live presentation are the product’s clearest strengths. Teams can arrange evidence in sequence, publish documents at selected pages, and apply highlights or zoom levels. Practice Mode supports witness examinations and mock trials, while role-based and personalized views can tailor what participants see. An optional hot-seat operator workflow adds another operating model for hearings. These capabilities give Ostentus a focused approach to exhibit management and evidence control rather than a general-purpose litigation workspace.
RelativityOne is central to the product’s fit: evidence can be presented directly from that environment without exporting data. Automatic, downloadable presentation logs and searchable records of published evidence and hearing events add useful accountability for proceedings. Pricing is handled through Delium’s sales process, with prospective users directed to book a demonstration. Ostentus should suit RelativityOne-centered litigation teams that need preparation, presentation, practice, and recordkeeping in one workflow. Teams using another review platform, or seeking a wider case-management system beyond evidence presentation, should look elsewhere.
