Transparency
Comma’s WhatsApp and Signal capture methods are published on GitHub. You can read them, audit them, share them with legal, and ask detailed questions before signing. No NDA required.
MirrorWeb’s capture methodology — including how its Trusted Contacts app intercepts and archives messages at the device level — is not publicly documented. For firms with IT security review requirements before deployment, understanding the capture architecture is a prerequisite, not an afterthought.
Pricing
Comma publishes its pricing publicly. One flat rate, all channels included, exports free. MirrorWeb markets “clear pricing” but requires a discovery call before you see a number. Knowing the cost up front changes how fast you move through procurement.
For enterprise deployments — multi-entity networks, broker-dealer groups, RIA aggregators, custom data residency, or private cloud — talk to us about enterprise pricing.
The App Requirement
MirrorWeb’s mobile capture requires employees to download the Trusted Contacts app on their personal devices. That’s a meaningful deployment hurdle: employee adoption, device policy approvals, IT rollout, and ongoing management of app versions across a workforce. For firms operating under BYOD policies, asking employees to install compliance software on personal phones adds friction — and creates a gap whenever someone doesn’t.
Comma does not run on employee devices. No app to install, no MDM enrollment, no local footprint. Archiving happens off-device. If the message is delivered, it’s captured, regardless of whether the employee has updated an app or opted in that week.

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)
