Enterprise-focused Email Archiving & Compliance Platform
A compliance-ready platform built for scale, security, and verification. Designed to handle tens of terabytes of email data with zero tolerance for data loss.
The Problem
Most archiving solutions fail in one of three ways: they mix business logic with ingestion, treat security as an afterthought, or collapse under real-world data volumes. 1Archiver started with a simple question: 'What if we built an email archiver the way it should actually be built — safe, secure, fast, and defensible in court?'
Architectural Challenges
The platform needed to handle tens of terabytes of email data, multiple providers (IMAP, Exchange, Gmail), and complex legal holds with zero tolerance for data loss.
Our Approach
Instead of rushing to implementation, we treated this as a systems engineering problem, not a CRUD app.
1. Designing for Compliance First
We separated responsibilities at a system level:
- Connectors (The Edge): Responsible only for fetching raw email data (IMAP/Exchange/Gmail). Stateless, no filtering.
- Workers (The Muscle): Responsible for data integrity (SHA-256 hashing, Deduplication, Secure blob storage).
- Compliance Core (System of Record): Authoritative source for retention policies, legal holds, audit logs, and access control.
2. Security Was a Default, Not a Feature
Every decision was made assuming hostile environments:
- Immutable data once ingested
- Tamper-evident audit logs
- Clear separation between raw data and indexed/searchable metadata
- No connector allowed to 'decide' what data is important
3. Built for Scale from Day One
We designed the system to scale horizontally:
- Streaming ingestion via message queues
- Workers that scale independently from the UI
- Search indexes decoupled from raw storage
- Metadata-driven schemas to support future features without migrations
4. Technology Choices That Serve the System
We intentionally avoided 'over-engineering' while choosing tools that survive enterprise workloads:
- Use battle-tested components where correctness matters
- Favor explicit data flows over hidden magic
- Design schemas assuming audits, not demos
The Outcome
1Archiver is now a compliance-ready platform, not just an MVP.
Key Achievements
- Secure, verifiable email ingestion
- Clear separation of concerns
- Scalable search across massive datasets
- Architecture ready for on-prem and cloud deployments
- Built to pass audits, not just demos
