The Jatheon alternative with review built in, not bolted on.
Jatheon is a pure-play archiving vendor with appliance and cloud options — genuinely comparable ground, since Grotabyte also runs on-premise. The difference is what happens after capture: semantic search, early case assessment, TAR with defensible recall, and productions counsel can file, without moving data to a second system.

Why teams switch from Jatheon to Grotabyte
The capabilities that matter most when your archive has to do more than store email.
The archive is also the review platform
Jatheon archives and searches. Grotabyte runs early case assessment before any index is built, TAR with a held-out control set and elusion testing, privilege review with redaction as removal, and Concordance DAT plus Opticon OPT productions with family-aware Bates numbering — against the archive itself, so nothing is collected twice.
Search by concept, not just keyword
Semantic search lets reviewers ask questions in natural language and retrieve results by meaning — combined with Boolean, proximity, entity, and metadata queries for precision.
AI conversations become records
Claude Enterprise chats, projects, attachments, and agent sessions are captured through Anthropic's Compliance API and archived alongside email. Each turn is kept as its own record rather than a transcript per conversation, so a supervision policy can catch the prompt that leaked the client list and a hold scoped to a date range knows which day it was said.
Investigations in minutes, not months
Customers have cut eDiscovery timelines from months to minutes, with chain of custody, legal holds, TAR/CAL review with elusion testing, and Concordance DAT + Opticon OPT productions with Bates numbering built in.
Deploy your way
On-premise or cloud from the same build — deployment is one environment variable, not a different edition. Per-tenant OIDC single sign-on routed by verified domain, passwordless email sign-in, and ten least-privilege roles, so security and IT keep full control.
Compliance across every mandate
A sealed, hash-chained ledger, retention policies, defensible deletion, and workflows for FOIA statutory deadlines, SEC/FINRA supervision, HIPAA, and CJIS — purpose-built for regulated industries.

Frequently asked questions
What teams evaluating Grotabyte against Jatheon ask most.
Grotabyte replaces email-centric archiving with one archive across Microsoft 365, Google Workspace, on-prem Exchange, IMAP, AI assistants, and legacy PST files. Most teams migrate an existing Jatheon archive via standard imports (PST, OST, EML, MSG, MBOX) and expand coverage to Teams chats, files, and AI conversations.
