Hadrius is an AI-native compliance platform built for SEC and FINRA regulated RIAs and broker-dealers. If you’re evaluating an all-in-one compliance OS — covering communications archiving, marketing review, trade surveillance, and employee oversight in a single platform — it may be on your list. Here’s how Comma Compliance compares across architecture, channel coverage, and exam readiness.
At a Glance
Hadrius is a broad compliance OS covering marketing review, trade surveillance, employee oversight, and communications archiving. Its channel list is not publicly documented, and coverage of encrypted mobile channels like iMessage and Signal is unconfirmed. Personal vs. business conversation filtering, custom policy matching, and case management depth are undocumented. Comma Compliance is purpose-built for communications compliance: capture, archive, supervision, policy matching, and exam-ready case management across 35+ confirmed channels — with open-source transparency and flat per-user pricing.

When Hadrius may be a better fit
- The firm needs trade surveillance — monitoring employee and client trading against restricted lists, blackout windows, and pre-clearance.
- They’re a small RIA wanting a single vendor for their entire compliance program — not just communications archiving, but the full SEC compliance stack in one place.
- Mobile capture isn’t the priority. If the firm primarily communicates over email and Slack on corporate devices, Hadrius’s weaker mobile channel coverage is less of a concern.
The Channel Transparency Gap
Hadrius claims 30+ channels but does not publicly document which channels are covered. Coverage of encrypted mobile channels like iMessage and Signal is unconfirmed. Comma Compliance covers 35+ channels, published and verifiable, including iMessage, WhatsApp, Signal, and Android — with open-source capture pipelines for WhatsApp and Signal so firms can see exactly how capture works before they buy.
The Pricing Transparency Gap
Hadrius does not publish pricing, requiring a custom quote before firms can evaluate cost. Comma Compliance offers flat per-user pricing — no custom quotes, no per-connector fees, no surprises.
Due Diligence
Questions to Ask Any Compliance Vendor
- 01
Where exactly is the message first captured - at the point of delivery, or after a backup or sync cycle?
- 02
What conditions must be true for a message to be captured? What happens if any of those conditions aren't met?
- 03
If a user edits or deletes a message before capture occurs, what version gets archived?
- 04
Can you show documentation - architecture diagrams, code, or an independent audit - of how your capture actually works?
- 05
Where are encryption keys stored, and who controls them?
- 06
Are all channels included in the base price, or are there per-connector fees?
- 07
Are there export or egress fees?
- 08
Does your case management workflow support regulatory examination prep?
- 09
Can cases be opened directly from flagged message threads?
- 10
Is any client data used to train your models? Under what conditions?
- 11
Can we adjust, refine, or contribute feedback to my policy models? (e.g., different languages, customer-complaint responses)
