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

The Data Protection Officer

Weighted verdict

Sees a ticket archive for what it is: years of personal data customers typed themselves, including the things they should not have. Wants retention that executes, redaction, an audit of who read what, and an answer on whether vendor support can open a ticket.

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

Scored by The Data Protection Officer

Ticketing, queues & SLA

How this is scored

The engine: how work is routed, prioritised, escalated and measured — and whether an agent can find the ticket they need among ten thousand.

0 — A shared mailbox with labels; no ownership, no status model, no history beyond the thread.

3 — Tickets with assignment and open/closed status, but routing is manual, there are no SLA timers and search covers subject lines only.

5 — Queues with rules-based routing, priorities, a working status model, SLA timers with breach warnings, and full-text search across ticket bodies.

8 — Business-hours-aware SLA policies per queue or customer, escalation chains, macros and triggers, merge and split, and reporting on first-response and resolution time by agent and queue.

10 — The workload is managed rather than merely tracked: capacity-aware assignment, SLA per contract with reporting an account manager could show a customer, audit of every status change, and search that finds the ticket from a half-remembered phrase.

Report an error

The Data Protection Officer

Routing is real — 'Omnichannel-Verteilung' at Team tier, skills-based distribution at Professional, macros ('Vorformulierte Antworten'), triggers and dashboards are all listed. But the evidence is silent on SLA timers, escalation chains, merge/split and search, and the audit of every status change I'd want on the compliance side appears only as Enterprise-plan audit logs [E3 via E2 features]. 1 2

Channels in one queue

How this is scored

Email, chat, phone, portal, messengers and social — judged on what actually lands in the same queue with the same history, not on how many channel logos the marketing page carries.

0 — Email only.

3 — Email plus one more channel, but the second lives in its own inbox: no shared history, and a customer who switches channel starts again.

5 — Email, a web form or portal and live chat all landing as tickets in one queue, with the customer's history visible whichever channel they used.

8 — The above plus telephony integration with call logging, at least one messenger (WhatsApp, Signal or similar) with its consent handling stated, and a customer portal where a requester can see their own tickets.

10 — Channel is an implementation detail: every channel including voice and messengers writes to one conversation with one history, agents answer from one screen, and the customer can move between channels mid-issue without repeating themselves.

Report an error

The Data Protection Officer

Email, live chat, telephony, messaging, community forums and a customer portal are all evidenced, with omnichannel routing and a 'unified platform across voice and digital channels' claim pointing at one queue. Held back from full marks because no messenger is named and no consent handling is stated anywhere — precisely the page an auditor turns to first. 1 2

Report an error

Knowledge base & deflection

How this is scored

Whether the product reduces the number of tickets as well as organising them: public help centre, article workflow, suggestions to agents and to customers.

0 — No knowledge base; answers live in agents' heads and old tickets.

3 — A basic article list, public or internal, with no editorial workflow, no versioning and no link between articles and tickets.

5 — A searchable public help centre with categories, draft and publish states, and agents able to insert an article into a reply.

8 — Article suggestions to the customer before they submit and to the agent while they answer, multilingual articles, review dates that flag stale content, and reporting on which articles deflect.

10 — Knowledge is a managed asset: gaps identified from unanswered tickets, article performance measured against ticket volume by topic, versioned content with approval, and deflection reported as a number the team can act on.

Report an error

The Data Protection Officer

A knowledge base, community forums and a public Guide help centre with custom-domain TLS exist, and AI Agents plus 'Automatische Hilfe' automate answering with claims of up to 80% automation. But nothing on editorial workflow, versioning, article-to-ticket linkage or deflection reporting — knowledge is present, not managed. 1 3

Customer data protection

How this is scored

A ticket archive is personal data written by the data subject. Retention, deletion, access control, subject rights, and what the vendor does with attachments — judged on what executes rather than what is promised.

0 — No retention policy stated, no deletion path, agents all see everything, and no DPA is published.

3 — A DPA on request and coarse roles; deletion is described as something the customer arranges, and there is no stated retention period.

5 — A signable DPA published, configurable agent roles and queue-level visibility, a stated retention period, and deletion of a requester's data that can actually be executed.

8 — Automatic retention rules per queue or data category, attachment handling stated, an audit log of who opened which ticket, documented support for access and erasure requests, and pseudonymisation or redaction of ticket content.

10 — Built for a data-protection audit: retention executed and evidenced per category, field-level redaction, full audit trail, subprocessor list published, and the vendor's own support access to customer instances documented and consent-gated.

Report an error

The Data Protection Officer

Redaction is genuinely native and executable — manual redaction of comments, secure attachment deletion, and automatic credit-card redaction down to logs and database entries — with documented subject-rights tooling (access, rectification, deletion, objection) and a published subprocessor list. But the configurable retention policies, data masking and access logs sit in a paid add-on, audit logs begin only at Enterprise, and the evidence never answers whether Zendesk's own support can open a customer ticket. 3

Report an error

Integrations & API

How this is scored

The systems a helpdesk has to reach — CRM, shop, order management, identity — and whether the API is documented for building or gated behind a partner conversation.

0 — No API and no named integrations; context is copied in by hand.

3 — A handful of native integrations and a read-mostly API, with no webhooks and no documented rate limits.

5 — Named integrations for common CRM and shop systems, a documented REST API with keys, webhooks for the core ticket events, and SSO.

8 — Maintained bidirectional integrations, customer context from other systems shown inside the ticket, SCIM provisioning, documented rate limits and a sandbox.

10 — A component rather than a destination: versioned API with a deprecation policy, event streaming both directions, an app framework for in-ticket extensions, and integrations the vendor maintains rather than lists.

Report an error

The Data Protection Officer

'APIs und Entwickler:innen', an AI App Builder and a sandbox environment are evidenced, with SAML/OIDC SSO on the security page. Not a single named integration — no CRM, no shop — and no webhooks, rate limits or SCIM anywhere in the evidence. 1 2 3

European sovereignty

How this is scored

Where the ticket archive lives, who the contracting entity is, which subprocessors touch it, and whether vendor support can read customer data. 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 hosting offered as an option while the contracting entity is non-EU, or the subprocessor list is absent.

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

8 — EU or DACH hosting with a named data-centre provider, EU contracting entity, full subprocessor list published, and any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor in the EU, certification published, and a self-hosted or private-cloud option for buyers who need the archive on their own infrastructure.

Report an error

The Data Protection Officer

The contracting entity is Zendesk, Inc. of San Francisco, and EEA hosting is merely one option among US, AU and JP on AWS — EU residency as an opt-in, not a standard. The published subprocessor list with names and locations is to their credit, but there is no EU entity, no self-hosted path, and nothing governing vendor support access to EU-hosted instances. 2 3

Pricing transparency

How this is scored

Whether a support lead can compute the real annual invoice for their agent count — including the channels and features they actually need — from public pages alone.

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

3 — A per-agent headline exists, but the tier where the needed channel or SLA feature begins is unstated, or light-agent and contact limits are not mentioned.

5 — Per-agent prices public for the main tiers with billing period stated, but at least one commonly needed capability (telephony, messengers, SLA policies) sits in an unpriced bundle.

8 — Every tier and add-on priced publicly with per-agent maths, billing period, minimum term and VAT treatment stated; only genuinely custom enterprise work lacks a number.

10 — Complete price computability: a calculator or table producing the annual invoice for a given agent count and channel selection, including usage-metered channels and overage.

Report an error

The Data Protection Officer

Three Suite tiers and three add-ons carry public per-agent prices with the billing period stated, and even telephony is priced at 82 €/agent/month. But VAT treatment and minimum terms are unstated, Enterprise is 'Vertrieb kontaktieren', and the advanced data protection add-on — the one I would need — has no price on the captured pricing page at all. 2
