ViewExport vs Onna
Overall: ViewExport is a lightweight eDiscovery tool focused on Slack, which can be bought and launched within minutes. Onna has more data sources and connectors, is much more expensive, and requires a full sales process to purchase an annual license.
Solution Comparison
ViewExport doesn't yet have connectors for Teams, Google, or others. We just focus on Slack, so we're easier to use and priced appropriately.

Private Equity Owned or Closely Held?
When you do business with ViewExport, you're working directly with the partners who own and operate the business. Your quality of customer support is stellar. There's nothing wrong with buying from a PE-backed enterprise; it's just different.

The Slack export viewer built for review and audit.
Legal and IT teams hit walls fast: no way to filter by date range, no way to search across DMs or private channels without triggering "joined channel" alerts, and no way to make sense of raw JSON files without hours of manual effort.
Native Slack tools don’t support scoped date searches well
Filtering Slack messages by date range isn’t easy natively—making legal holds, audit prep, and early case assessment slow and error-prone.
Accessing private channels in Slack notifies users — not ideal for audits
Joining private channels triggers alerts and raises red flags in sensitive HR, compliance, or internal investigations.
Slack exports come in raw JSON, unreadable without technical help
Parsing Slack’s JSON exports eats up billable hours and internal IT time before legal review even begins.
Enterprise-Grade Security, Built for Legal Workflows
ViewExport is designed with strict security, access controls, and audit trails to meet your legal, IT, and compliance standards.
Immuntability
Audit logs are locked by default and cannot be altered or removed by any user — including administrators. This preserves a tamper-proof record of activity for legal defensibility and regulatory assurance.
Retention
All audit logs are automatically retained for a minimum of 12 months, in line with common legal and regulatory requirements. Optional custom retention settings allow longer storage where needed.
Access Control
Only designated administrators with the correct roles and permissions can view or query audit logs. This reduces exposure risk and aligns with internal access control policies and compliance frameworks.
Encryption
Audit logs are encrypted at rest using industry-standard protocols. This ensures that sensitive access data remains secure, even in the unlikely event of a system compromise.
Sensitive Data Protection
Passwords, access tokens, and API keys are automatically filtered and excluded from all logs, preventing accidental logging of high-risk secrets, and protecting both internal systems and user privacy.
Compliance Support
Audit logging helps you align with your GDPR, SOC 2, ISO 27001, and HIPAA compliance requirements. Combined with access control and retention policies, we support your audit-readiness out of the box.

Which Slack plans is ViewExport compatible with?
We're compatible with all Slack plans: Free, Pro, Business, and Enterprise.
Can I upload private Slack channel and message data?
You can upload anything that is included with the .ZIP file that contains your .JSON exports from Slack. If those files contain private channel data, they'll be searchable in ViewExport as well. However, we can't help you get data that Slack doesn't already give you.
What does the implementation process entail?
There's no implementation required: ViewExport is as easy as setting up an account, and uploading a .ZIP file. That said, we're happy to walk you through configuration and best practices.
