Read this page as one judge. Each weighs the same scores by what they care about.

The Compliance Counsel

Weighted verdict

Will one day have to produce this archive, edits and deletions included, to a regulator or a court. Wants legal hold, an export a lawyer can work from, retention per channel, and an audit trail that survives the admin who made the change.

Same scores as the panel view — this lens weights them the way this judge cares.

Channels, threads & search

How this is scored

The daily surface: channel model, threading, mentions, files, and whether search can find a decision made eighteen months ago.

0 — Flat group chats with no threads; search covers recent messages only, and history is capped.

3 — Channels and direct messages with basic search, but threading is awkward or absent and file handling is a plain attachment list.

5 — Public and private channels, real threads, mentions and reactions, file sharing with previews, and full-text search across the whole history.

8 — Cross-organisation or guest channels with clear boundaries, message editing history, pinned and saved items, search with filters by channel, person and date, and a documented history limit or none at all.

10 — The archive is a working knowledge base: search that ranks well across years, threads that stay readable, channel lifecycle management (archive, rename, merge) without losing history, and export of a conversation in a form a human can read.

Report an error

The Compliance Counsel

Dedicated rooms, one-to-one and group chat, and a genuinely rich set of search filters by contact, file, image, video, link and flag are evidenced — but conversation threading amounts to replies that encapsulate the original message, and the captured pages state that search and filters are unavailable under Standard encryption, so an organisation's discovery surface depends on which encryption mode an admin chose. We found no public information on a documented history limit, message-edit history, pinned items, or exporting a conversation in a form a human can read, which is what a production request will eventually require. 2 3 4 7 8

Report an error

Encryption & access control

How this is scored

What is encrypted and against whom, plus who can reach which room. Judged on documented mechanism, since "encrypted" in this category usually means the vendor holds the keys.

0 — Transport encryption only, undocumented; no role model beyond admin, guests indistinguishable from members.

3 — TLS and encryption at rest with vendor-held keys, basic roles, and guest access that mostly works.

5 — The above plus configurable roles per channel, SSO, guest accounts with scoped visibility, and a clear statement of what the vendor can read.

8 — Optional end-to-end encryption for direct messages or private rooms with the trade-offs named, device verification, session management an admin can revoke, and documented key handling.

10 — End-to-end encryption as a first-class mode — documented or open cryptography, cross-device key management that ordinary users survive, identity verification, and the vendor stating plainly what it cannot decrypt.

Report an error

The Compliance Counsel

End-to-end encryption is a documented, admin-selectable mode with the trade-offs named plainly — web access restricted, monitoring unavailable, users responsible for their own private keys and locked out if they lose them — alongside role-based permissions at feature level, LDAP/Active Directory/SSO, and admin-enforced MFA with five methods and idle timeout. It sits below the top band because we found no public information on device or identity verification, on session management an administrator can revoke, and the cryptography is named (AES-256, public-private keypair) but not published for independent review. 4 5 6 7

Report an error

Retention, discovery & co-determination

How this is scored

The archive as a legal object: retention policies, export for discovery, audit, and the monitoring features a works council will ask to have switched off.

0 — No retention policy, no export beyond a manual copy, no audit log, and presence or activity analytics that cannot be disabled.

3 — Manual export of some data and a global history limit, but no per-channel retention, no audit log and no admin control over analytics.

5 — Configurable retention per channel or workspace, admin export in a documented format, an audit log of administrative actions, and status or presence that a user can control.

8 — Legal-hold and eDiscovery export including edits and deletions, retention executed per policy and evidenced, full admin audit trail, and activity analytics switchable off organisation-wide.

10 — Built to pass a works agreement and a subpoena on the same day: granular retention with documented deletion, discovery export a lawyer can use, complete audit, and no individual-level productivity scoring anywhere in the product.

Report an error

The Compliance Counsel

The one strong item is the audit claim — every action logged, exportable, SIEM-ready via Syslog — the kind of trail that can survive the administrator who made the change. But we found no public information on retention policy configuration per channel or workspace, legal hold, eDiscovery export including edits and deletions, or any export format a lawyer could work from; the only retention-adjacent statement is that on your own servers you decide how long data is kept, which is a custody claim rather than a policy engine. Self-destructing and disappearing messages are marketed features, and nothing documents how deletions are captured for a later production. 4 6 7

Deployment & data custody

How this is scored

Whether the customer can hold their own archive: self-hosting, private cloud, open source, federation, and what an exit actually looks like.

0 — Cloud-only, proprietary, with export limited to a partial archive.

3 — Cloud-only, but with a documented full export in an open-ish format.

5 — A private-cloud or dedicated-instance option, or a self-hosted edition that lags the cloud significantly; full export documented.

8 — A genuine self-hosted edition close to feature parity, or open-source core with a documented upgrade path, plus complete export including files and metadata.

10 — Custody is the customer's: open-source or source-available server, self-hosting supported as a first-class deployment, open protocol or federation, and a migration path in and out that the vendor documents rather than resists.

Report an error

The Compliance Counsel

Custody is genuinely on offer: a self-hosted server installed with Docker or a Windows installer in four documented steps, deployable into your own AWS, Azure or GCP tenancy, on MySQL 8+ you can inspect, with a fully air-gapped edition and named defence and government customers. The vendor markets the on-premise edition as an alternative to open-source platforms, and we found no public information on a documented full export including files and metadata, or on a migration path in or out — which is the other half of custody. 2 6 7

Report an error

Integrations & extensibility

How this is scored

Bots, webhooks, app framework, identity — whether the chat becomes the place work is noticed, and whether that is buildable without a partner agreement.

0 — No API, no webhooks, no bots.

3 — Incoming webhooks and a handful of native integrations; no bot framework, no documented limits.

5 — Documented REST API, incoming and outgoing webhooks, slash commands, a bot account model, and SSO.

8 — A proper app framework with interactive components, event subscriptions with retries, SCIM provisioning, documented rate limits and a sandbox.

10 — A platform: versioned API with a deprecation policy, an app directory or plugin system with permissions a customer can audit, and integrations the vendor maintains rather than lists.

Report an error

The Compliance Counsel

Zapier is offered bidirectionally with ready-made templates and a handful of native apps such as Gmail, Zoom and Asana, and there are documented backend APIs, JavaScript chat SDKs and SSO. We found no public information on webhooks of the vendor's own, slash commands, a bot account model, SCIM provisioning, documented rate limits or a sandbox. 7 8 9

Report an error

European sovereignty

How this is scored

Where the archive and its metadata live, who the contracting entity is, which subprocessors touch it. Independently sourced by the sovereignty pipeline; scored here as this buyer weighs it.

0 — Non-EU vendor and contracting entity, hosting unstated or non-EU, subprocessors unnamed.

3 — EU data residency offered for message content while metadata, search indexes or support tooling remain non-EU, or the contracting entity sits outside the EU.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain — notifications, AI features, analytics — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, full subprocessor list published, any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor European, certification published, and a self-hosted option that removes the question.

Report an error

The Compliance Counsel

Nothing in the captured pages establishes the vendor's legal entity or jurisdiction, its ownership, where a SaaS archive and its metadata would be hosted, or a single subprocessor — every attribute I would need for a data-processing agreement is unstated. The mitigating fact is that the product can run entirely on the customer's own infrastructure, including air-gapped, which removes the processing chain from the question, and European defence bodies appear among the named customers. 6 7

Pricing transparency

How this is scored

Whether a buyer can compute the annual invoice for their headcount — including the retention, compliance and guest features they actually need — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A per-user headline exists, but the tier where retention control, SSO or compliance export begins is unstated.

5 — Per-user prices public with billing period stated, but at least one commonly needed capability (unlimited history, SSO, eDiscovery) sits in an unpriced enterprise tier.

8 — Every tier priced publicly with per-user maths, history and storage limits, feature boundaries, minimum term and VAT treatment stated; self-hosted licensing priced too where offered.

10 — Complete price computability: annual invoice derivable for a given headcount and deployment choice, including guest users, storage and any per-instance licence.

Report an error

The Compliance Counsel

We found no public prices at all: the on-premise pricing page routes every buyer to a tailored quote within one business day, so the annual invoice is a sales conversation, and we found no public information on per-user maths, storage or history limits, minimum term or VAT treatment. A 15-day full-featured trial without a credit card is reasonable evaluation access, but it does not let a buyer compute an invoice for their headcount from public pages. 2 4 6 7
