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](/platform-integrations), 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.
