TOP MISSING FEATURES
Why Jatheon is a stronger
alternative to Office 365
Industry-leading advanced search
Jatheon’s advanced search lets you create and execute complex searches by filtering emails matching different criteria, keywords, and phrases. Based on the latest search technology, it lets you run fast, repeatable, organization-wide investigation searches across huge volumes. Results can be filtered, saved, and exported for review or ediscovery, giving compliance teams confidence and precision during audits and investigations.

Advanced export
Jatheon’s export process is built for real-world investigations at scale. Whether you’re exporting 500K or several million emails, the system completes it without forcing you to break the task into artificial batches. Large exports are automatically generated as multiple manageable PST files. Microsoft 365 exports are structured around predefined package and PST size limits — an approach many users describe as cumbersome when dealing with high-volume, time-sensitive requests.

Fully customizable user roles
With Jatheon, you can fully customize roles and permission levels to protect sensitive data. The platform comes with three default roles: Admin, Compliance Officer, and End User, all of which you can customize. Plus, you can add new roles and define them based on departments, user groups, seniority levels, or any other criteria applicable to your organization and its unique needs.

Centralized archive for all your communication channels
Jatheon delivers true multi-channel communications archiving, capturing email, chat, collaboration tools, mobile messaging, social media, and files in one centralized, compliant archive. While Microsoft 365 provides strong retention for its native workloads like Exchange, Teams, OneDrive, and SharePoint, extending coverage to platforms such as Slack, Zoom, WhatsApp, and social media often requires connectors and third-party capture workflows. Jatheon gives you everything in a single platform.

Support for ediscovery and compliance
Jatheon’s comprehensive enterprise data archiving features help you browse through all business communication channels and retrieve data essential for ediscovery requests. You will minimize costs associated with FOIA requests and ensure full compliance with key regulations in your industry.

Seamless migration and no vendor lock-in
Migrating legacy archives into Microsoft 365 is often slow, incomplete, or costly. Jatheon provides fast, verified migration from more than 30 legacy systems, without losing metadata or compliance context. Microsoft 365 customers retain data ownership, but data portability, advanced ediscovery, and large-scale exports may depend on licensing tiers and tooling. Jatheon removes export fees and simplifies data portability with no contract termination costs.

Frequently asked questions
Everything you need to know about the product and billing
Why should my organization consider Jatheon as an alternative to Microsoft Office 365?
Microsoft 365 is primarily designed for productivity and collaboration, not compliance archiving. Jatheon offers a dedicated, AI-enabled archiving platform that captures data across all communication channels, supports advanced ediscovery, and ensures full regulatory compliance, making it a stronger Office 365 alternative for regulated industries.
Can Jatheon archive Microsoft 365 and other communication platforms together?
Yes. Jatheon integrates with Microsoft 365 and captures data from email, Teams, OneDrive, and other sources. It also archives Slack, Zoom, social media, and mobile data, which gives organizations a unified archive across all platforms.
What makes Jatheon a better Office 365 alternative for ediscovery?
Jatheon’s ediscovery tools include advanced search with Boolean, proximity, and fuzzy operators, legal hold tags, tagging and redaction options, and export in multiple formats. Office 365’s native tools require additional licensing and lack the same level of control and speed.
Is Jatheon a secure and compliant alternative to Office 365?
Absolutely. Jatheon is built on AWS infrastructure, with encryption in transit and at rest, role-based access control, and compliance with FOIA, FINRA, HIPAA, GDPR, and other major regulations, making it a secure Office 365 alternative for public and private sector organizations.
How does Jatheon handle retention and legal hold compared to Office 365?
Unlike Microsoft 365, where retention policies can be complex and tied to storage limitations, Jatheon provides transparent, policy-based retention and flexible legal hold management. Users can easily preserve, manage, and release records across multiple data types.
