The Works Council Advocate

Weighted verdict

Knows that a chat log is a record of who spoke to whom at what hour. Wants presence a person controls, no individual activity scoring anywhere, retention that deletes rather than hides, and analytics that can be switched off across the organisation.

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

Scored by The Works Council Advocate

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 Works Council Advocate

Group chats, reactions, polls and file sharing are confirmed, but the evidence shows no threads, no channels, no mentions, and no search capability at all — eighteen months back, a decision here is found by scrolling, if the client still holds it. External communication is only a 'coming soon' EasyConnect. This sits between the flat-chats anchor and the basic-search anchor, closer to the bottom. 1 2

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 Works Council Advocate

End-to-end encryption is not an option, it is the product, with the vendor stating plainly that 'not even Threema has access', plus Perfect Forward Secrecy, open source code and regular independent audits. I dock a point only because the evidence is silent on device verification, cross-device key handling and admin session revocation — everything else here is what I would demand in a works agreement. 1 2

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 Works Council Advocate

The only retention numbers in the whole sheet are for website cookies, forms and truncated IP logs — nothing on message retention policy, admin export, eDiscovery or an audit log for the product itself. On the plus side for co-determination: no activity analytics or individual scoring is evidenced anywhere, and there is an off-hours policy plus availability status, which is exactly the presence control I ask for. Absence of the legal-tooling half pulls this down to just above the manual-copy anchor. 1 3

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 Works Council Advocate

OnPrem self-hosting with air-gapped operation, white-labeling and an admin API is genuine custody, not a checkbox, and the cloud runs on the vendor's own servers in named Zurich data centres. But the evidence evidences no export or migration path in or out, no federation, and OnPrem is priced 'custom' rather than sold as a first-class public deployment — so a real exit is asserted, not documented. 1 2

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 Works Council Advocate

There is a real API surface — integration API, admin API, Broadcast API with bots and feeds, MDM, metered gateway credits — but no webhooks, no slash commands, no app framework, no SCIM, no documented rate limits or sandbox, and directory sync with AAD costs extra without a stated price. This is automation plumbing above the webhook anchor, well short of the documented-API-platform anchor. 1 2

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 Works Council Advocate

The contracting entity Threema AG is Swiss, not EU — they even need an Art. 27 GDPR representative in Bonn — and hosting is on their own servers at a named ISO 27001 colocation partner in Zurich, which is geographically European but contractually outside the EU. Only one subprocessor (Livestorm, Ireland, webinars) is disclosed, and the pipeline itself marks product subprocessor exposure unknown. Switzerland on own infrastructure is better than most non-EU setups, but the entity and the undisclosed chain keep this just above the bottom anchors. 3 1

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 Works Council Advocate

Core at EUR 3 and Professional at EUR 5 per user per month, with annual billing stated, lets a buyer compute the SaaS invoice for any headcount. But the compliance-relevant choices — self-hosted OnPrem at 'custom', and AAD sync as an unpriced additional charge — sit behind a sales conversation, and minimum term and VAT treatment are unstated; only a 30-day trial is public. 2 1
