TOP MISSING FEATURES

Why Jatheon Is a Better Option

All-in-one archiving

Mimecast archive covers email and some collaboration tools, but misses critical channels like SMS, WhatsApp, iMessage, social media, and voicemail. Regulated firms often need costly third-party add-ons to fill the gaps. Jatheon eliminates this with one platform that natively captures 25+ data types, email, texts, social, instant messaging, video, and more, removing cost and complexity.

All-in-one archiving

Flexible data-retention policies

Your data needs to meet different rules. We give you granular control over your data’s lifecycle, allowing you to create specific retention rules based on groups, jurisdictions, or data types. This flexibility ensures you can easily meet complex global and industry-specific regulations (e.g., GDPR vs. SEC Rule 17a-4).

Flexible data-retention policies

Simple and modern interface

Mimecast reviews often point out to the platform’s complex interface, particularly in the administrative and search functions. This can create slower workflows for IT, legal, and compliance teams who need to work under time pressure. In contrast, Jatheon is designed for a seamless user experience, with a modern, intuitive UI that makes it easy for your teams to search, review, and manage archived data efficiently, saving valuable time and reducing the learning curve.

Simple and modern interface

Powerful ediscovery capabilities

Jatheon’s powerful ediscovery tool is built for speed and precision, with advanced search capabilities (including AI-assisted review), legal-centric workflows, and robust case management tools that help compliance and legal teams respond to requests quickly and accurately, which is particularly important for regulated industries with frequent audits and litigation.

TESTIMONIALS

We use it primarily for open records requests. Searching is a breeze through 10 years of email. By adding filters, you can narrow your results down to exactly what you need. You can export to PDF for easy viewing and to MBOX for sending to the attorneys. Ediscovery is another solid use case for this product. The lawyers will love you.

IT Manager in Education

I’ve been using Jatheon for several years. Their product is reliable and works well. They also provide fantastic support. We recently went through a migration to one of their newest email archive appliances, and it went very smoothly. In a short time, they had the new appliance online, and all the data from the old appliance migrated over.

Senior Network Administrator in Healthcare and Biotech

The ease and user-friendly interface is what drew me to this product. During the setup, it was very smooth working with the person from Jatheon. Very quick responses if I had any questions. Overall experience is definitely 5-star.

Director of Network IT in Education

WThe product works very well, and the support is excellent. It is easy to deploy and use. We have a few of these features in another service we have, but that platform is nowhere as intuitive as this product.

Director, Systems & Programming in Education

The platform is consistently stable. Searches and exports run quickly enough that they don’t become a bottleneck for legal or compliance work.
