- Slack stores messages on US servers — every confidential discussion is a cross-border transfer without adequate safeguards for most EU regulated firms
- Slack has no concept of matter or client — confidential conversations about clients are mixed with lunch plans
- ShieldChat is end-to-end encrypted, Singapore-hosted (EU Frankfurt Q3 2026), linked to client/matter records, and audit-trailed
- HD voice and video calls are included via LiveKit — no Zoom needed
We need to say something uncomfortable: a lot of regulated businesses are using Slack, Teams, or WhatsApp for internal conversations that include confidential client information. Partner names, deal details, risk assessments, draft SARs, KYC concerns. All of it sitting in application servers operated by US companies, subject to US law, accessible under US government requests, and with no connection to the client record it relates to.
This is not a theoretical risk. This is how data breaches happen. This is how professional privilege gets complicated. This is how regulatory investigations find things you didn't intend to share.

The problem with consumer-grade messaging for regulated professionals
No matter context
When a partner sends a Slack message saying "I'm worried about the Carlson file — the UBO structure looks off," that message has no connection to the Carlson client record, no connection to the AML case file, and no connection to the compliance officer's task queue. The concern gets discussed and then disappears into the message history. Nothing is actioned. Nothing is documented. Nothing is connected to the people responsible for managing it.
No audit trail you own
Slack's audit logs are available on Enterprise Grid. So is your conversation history — to Slack, as a US company subject to US legal process. You do not own your message data. When a regulatory investigation requests communications records, you are at the mercy of a third-party company's data retention policies, export formats, and legal cooperation timeline.
Data residency
Slack's EU Data Residency feature moves some data to EU servers. But metadata, search indexes, and certain product functions still process data in the US. For truly Singapore-hosted communications with no US touchpoints, you need a different solution.

What ShieldChat changes in practice
The most immediate change is that internal conversations about clients become part of the client record. When the team discusses a KYC concern in ShieldChat, that discussion can be linked to the client's compliance file — creating a complete, searchable record of what was discussed, who said what, and what was decided. No more "I thought you were handling it."
The second change is culture. When people know their compliance conversations are properly governed and documented, they communicate more precisely. They escalate concerns in writing. They close loops. The act of having a proper record creates better professional habits.
The WhatsApp problem
While we're at it: WhatsApp. Used by professionals everywhere for quick client questions and team coordination. Owned by Meta. Data processed for advertising purposes. Not subject to any data processing agreement with your firm. Not auditable. Not GDPR-compliant for professional communications containing personal data. The FCA in the UK has fined firms specifically for WhatsApp-based communications that bypassed record-keeping requirements. This is real enforcement risk, not hypothetical.
Can ShieldChat replace our entire Slack workspace?
Yes — ShieldChat has channels, direct messages, threads, file sharing, voice and video calls, and a full mobile app. Teams that switch from Slack report the transition takes about a week to feel natural. The compliance integration makes it genuinely better for regulated work, not just equally good.
What about WhatsApp with clients?
Client-facing WhatsApp is a separate issue. For outbound client communications, HubSecure Secure Mail is built for governed client messaging. For clients who insist on WhatsApp, you should at minimum have a policy that no confidential matter details are shared via that channel — and document the policy.
