The Data Protection Officer

Weighted verdict

Reads every workflow as a chain of transfers. Asks where the execution log keeps its copy of the payload and for how long, which subprocessors and AI model providers a step sends data to, whether payloads can be masked, and what the approval trail records about employees before the works council asks.

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

Process design, forms & approvals

How this is scored

Modelling the process people take part in: a visual designer or BPMN, forms, approval steps with roles and substitutes, deadlines and escalation, and versioning of a process that is already running — judged on whether a business owner can change a process without breaking the instances in flight.

0 — Linear trigger-action chains only; no human steps, no forms and no statement on approvals or roles.

3 — A visual builder with branching and a simple approval step, but approvers are named individuals rather than roles, there are no deadlines or escalation, and changing a process has no versioning.

5 — A visual designer with conditions and parallel paths, built-in forms, approval steps assigned to roles or groups, deadlines with reminders, and versions of a process kept with the running instances on their original version.

8 — BPMN 2.0 modelling or an equivalent documented notation, substitutes and escalation chains, multi-stage approvals with four-eyes rules, forms in German with validation and file upload, a task inbox for participants, and a test or simulation mode before publishing.

10 — The process is a governed asset: version history with diff and rollback, migration of running instances to a new version documented, process analytics on cycle time and bottlenecks per step, and the design documented well enough that a business team can maintain it without the vendor.

Report an error

The Data Protection Officer

A running process is genuinely editable without breaking it: changes can apply to the single instance or publish as a new minor version, node properties carry assignee, deadline and escalation settings, and forms come with validation groups, file upload and a participant task list, with a debug mode for trial execution. We found no public information on the modelling notation, on substitutes, or on multi-stage approvals with a four-eyes rule, which is what the top of this scale asks for. 6 10 5 2

Connectors, API & on-premise reach

How this is scored

Reaching the systems a European company actually runs: maintained connectors judged by name rather than count, a generic HTTP and webhook step, custom connectors, and a way to reach systems behind the firewall without opening it.

0 — No connectors beyond email, and no API or webhook step.

3 — A large connector count on a logo wall, with no statement of which actions each supports or who maintains them, and no generic HTTP step.

5 — Named connectors with their triggers and actions documented, including Microsoft 365 and at least one ERP or accounting system common in DACH (e.g. SAP, DATEV, Microsoft Dynamics), a generic HTTP/REST step, inbound webhooks, and a documented API to start and query workflows.

8 — Custom connectors buildable from an OpenAPI description or code, an on-premise agent or self-hosted runner reaching internal databases and file shares, SOAP and database steps, OAuth handled per connection, and connector maintenance ownership (vendor, partner or community) stated.

10 — Integration is engineered: a versioned public API with a deprecation policy, connector changelogs, rate limits per connector published, event-driven triggers rather than polling where the source allows it, and the vendor maintaining the German-market connectors (DATEV, SAP, ELO or d.velop) itself.

Report an error

The Data Protection Officer

Integration is engineered rather than a logo wall: a generic HTTP step covering the common verbs and content types, SQL over a custom JDBC connected system, SOAP calls carrying WS-Security UsernameToken, OpenAPI-based integrations and OAuth per connected system, with Snowflake and Kafka connectors named and tiered. We found no public information on connectors for Microsoft 365 or DACH ERP systems, on inbound webhooks, on an API to start and query workflows, or on who maintains each connector. 8 12 7 2

Execution, error handling & monitoring

How this is scored

What happens when a step fails at 3 a.m.: retries, error paths, alerting, an execution history someone can search, limits on runtime and throughput, and a status page that admits incidents.

0 — Nothing stated about failed runs; an error stops the workflow silently.

3 — Failed runs are marked and an email is sent, but retries are manual, execution history is short or undocumented, and runtime and throughput limits are unstated.

5 — Automatic retries with configurable back-off, an error path or error workflow, a searchable execution log with input and output per step, failure alerts by email or chat, and runtime, payload and rate limits documented.

8 — Replay of a failed run from the failing step, idempotency guidance, queueing and concurrency controls, execution history retention stated per plan, monitoring exportable to the customer's own tools, and a public status page with incident history and an uptime commitment.

10 — Operations are designed for production: an SLA with service credits, horizontal scaling or high-availability setup documented for self-hosted installs, dead-letter handling, end-to-end tracing across workflows, and post-incident reports published.

Report an error

The Data Protection Officer

Failures are visible rather than silent — an Errors tab per process, Process History, configurable timeouts, graceful error returns from connector reads — and the HTTP log's copies of the payload are opt-in, truncated at 100,000 characters, capped at 7 days and 100 MB, masked of credentials and readable by system administrators only; a cloud SLA of 99.8–99.99% and high availability at 1-minute RPO are published. We found no public information on retry behaviour with back-off, on failure alerting, on replay from the failing step, on execution-history retention per plan, or on a public status page. 10 8 2 2

Governance, credentials & audit trail

How this is scored

Keeping automation from becoming shadow IT: roles and permissions, SSO, where connection credentials are stored, separate environments with controlled publishing, an audit trail of changes and approvals, and what the execution log retains of the payload. An approval record is also a record of employees' behaviour, so what the trail captures matters to a works council.

0 — Single-user accounts or one shared login; no roles, no audit log and no statement on credential storage.

3 — Admin and member roles and shared team folders, but credentials are visible to anyone who can edit a workflow, there is no audit log, and execution payloads are kept without a stated period.

5 — Role-based permissions per workflow or folder, SSO via SAML or OIDC, credentials stored encrypted and usable without being revealed, an audit log of workflow changes, and the retention period of execution data stated.

8 — Separate development, test and production environments with a publishing approval, SCIM provisioning, external secret stores supported, payload redaction or log-off per workflow, configurable execution data retention, and the audit trail exportable — with the fields it records about users described.

10 — Governance a works council and an auditor can both sign off: field-level masking of personal data in logs, delegated administration per department, a central inventory of every workflow and connection with its owner, certifications published (ISO 27001 or SOC 2), and documentation of what the platform records about individual users.

Report an error

The Data Protection Officer

From a data-protection seat this is the best-evidenced area: the Secure Credentials Store encrypts values and masks them in the interface, integration logging can be switched off per workflow and per console, truncates bodies, masks Authorization and credential headers, never outlives 7 days or 100 MB and is administrators-only, while Process History records executed actions and administrator roles gate start, pause and cancel. We found no public information on single sign-on, SCIM provisioning, separate environments with a publishing approval, an exportable audit trail, or which fields the trail keeps about individual employees — the record a works council asks to see — though SOC 1, SOC 2 and SOC 3 attestations are published. 12 8 10 2 11

Report an error

Hosting options & portability

How this is scored

Where the engine runs and whether the workflows can leave: cloud regions, self-hosted or on-premise editions, the licence of the engine, and export of workflow definitions in a format another tool or a later version can read.

0 — Cloud-only with no stated region, and no export of workflow definitions.

3 — Cloud-only with a region named, and an export that produces a proprietary file only the same product can import.

5 — An EU cloud region selectable, workflow definitions exportable as documented JSON or BPMN 2.0, and an API to read definitions and execution history for backup.

8 — A self-hosted or on-premise edition with its system requirements documented, workflow definitions versionable in Git, the engine's licence published, and a documented migration path between cloud and self-hosted in both directions.

10 — The customer owns its automation: an open-source or source-available engine, definitions in an open standard executable elsewhere, air-gapped installation supported, and a stated exit process that hands back definitions, credentials metadata and execution history in documented formats.

Report an error

The Data Protection Officer

The engine runs where the customer chooses: self-managed Kubernetes with validated platforms, tested versions, a customer-provided relational database inside or outside the cluster, high-availability and autoscaling options, a migration tool from server-based installations, and licence mechanics documented down to the 6-day temporary key. We found no public information on exporting workflow definitions in a format another tool could read, on holding definitions in Git, or on a documented migration between cloud and self-hosted in both directions. 14 14 2 13

European sovereignty

How this is scored

Who the contracting entity is, where workflows execute and where execution logs with their payload copies are stored, and who the subprocessors are — including the AI model providers behind any AI steps. Independently sourced by the sovereignty pipeline. A self-hosted edition counts only for the data that actually stays on the customer's servers.

0 — Non-EU vendor and contracting entity, execution location unstated, and subprocessors unnamed.

3 — An EU region offered as an option while the contracting entity is non-EU, or the subprocessor list is absent, or AI steps send data to model providers of unstated location.

5 — EU execution and log storage as standard and an EU contracting entity, but parts of the chain — AI steps, support access, telemetry — are non-EU without an explained safeguard.

8 — EU execution on named infrastructure, EU contracting entity, subprocessor list published with locations including AI providers, a DPA covering execution payloads, and a self-hosted option that sends no workflow data to the vendor.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, AI steps runnable on European or self-hosted models, certification published, and a self-hosted edition that works without any call home.

Report an error

The Data Protection Officer

The chain of transfers cannot be located: the independently sourced provenance places the vendor in Virginia, USA, and the captured pages name no execution or log-storage region, publish no subprocessor list, and name no provider or location behind the AI Agents and AI Copilot steps, while the privacy policy expressly steps aside for processing in the processor role. The documented self-managed edition, with workflow data on the customer's own cluster and database, is the only stretch of that chain I can place, and it earns the single point. 3 2 14

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the monthly cost of their own processes from public pages alone: what the billing unit is (task, operation, execution, run, user or flow) and what counts as one, the allowance per tier, overage prices, and the cost of premium connectors, self-hosting, environments and AI steps.

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

3 — A starting price exists, but the billing unit is undefined or what counts as one task or execution is unstated — the invoice is unknowable.

5 — Tier prices public with the billing unit defined and the monthly allowance given, but at least one commonly needed piece (overage, premium connectors, extra environments, self-hosted licence, AI steps) is unpriced.

8 — Every tier priced publicly with its unit, allowance and limits, overage priced per unit, premium connector and add-on prices listed, self-hosted licensing stated, minimum term and VAT treatment given.

10 — Complete price computability: the monthly cost derivable for a given number of workflows, runs and steps per run, with a published calculator or worked examples, every add-on and overage on a public page, and the effect of loops and retries on the count explained.

Report an error

The Data Protection Officer

The billing unit is stated — per user, per month, per app — and per-tier allowances are public, including AI Action limits of 200K, 500K and 1M per month, bot counts and portal limits. The captured pricing pages carry no monetary figure for any tier, and we found no public information on overage prices, premium connector costs, self-hosted licensing, minimum term or VAT treatment, so the monthly cost of a buyer's own processes is not computable. 2 2
