The Smarsh alternative you can run on your own hardware.
Smarsh is a communications governance platform with very broad channel coverage, and on breadth it is ahead. Grotabyte is the alternative for teams who need the archive to run where their policy says it runs — on-premise, cloud, or operated by us from the same build — with AI conversations kept as individual records rather than transcripts.

Why teams switch from Smarsh to Grotabyte
The capabilities that matter most when your archive has to do more than store email.
Where the archive runs is your decision
Smarsh captures more channels than Grotabyte does, and on breadth of capture it is ahead — if you need social, voice and every messaging network in one place, say so and we will tell you honestly. Grotabyte competes on control of the archive itself: one build that runs on-premise against your own filesystem, NAS or SAN with record keys that never leave the machine, in cloud storage you nominate, or operated by us — and storage dedicated to your tenant in every case.
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 Smarsh 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 Smarsh archive via standard imports (PST, OST, EML, MSG, MBOX) and expand coverage to Teams chats, files, and AI conversations.
