The short version

  • Only Keil MDK has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keil MDK pricing for Essential and Professional subscriptions not disclosed on primary site; Transcend value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • Prices and features above were last checked on 31 August 2026.

Transcend

  • A privacy team that currently fulfils requests by emailing system owners and wants machine evidence that deletion actually occurrednot Keil MDK

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

Transcend

  • Value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • Pricing is quoted and scales with data volume and integration count, so the cost grows precisely as the company grows, and there is no public anchor to negotiate against at renewal.
  • It is deep on fulfilment and consent but thinner than OneTrust on wider governance, third party risk and ethics programme management, so a large enterprise privacy office may end up running two vendors.
  • Deployment requires engineering time to install and authorise integrations into production data stores, which means the privacy team cannot buy and implement it alone and the project competes with engineering roadmap.
  • Automated deletion against production systems is a destructive operation, so organisations without good staging environments and confident data ownership move slowly and often run the tool in advisory mode for months before letting it execute.

Answered from the vendors’ own pages

Keil MDK: Does Keil MDK have a free version?

Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.

Source
Transcend: How is Transcend different from a subject request ticketing tool?

It executes the request against your systems through integrations rather than routing a task to a person. That is the whole product, and it is why the deployment requires engineering involvement.

Keil MDK: How much do Keil MDK paid editions cost?

Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.

Source
Transcend: What does it cost?

Nothing is published. Reported deals begin around 10,000 US dollars a year and rise with data volume, integration count and modules such as AI governance.

Transcend: Can it replace OneTrust?

For subject rights, consent and data mapping, often yes. For third party risk, ethics reporting and wider GRC programme management it is narrower.

Transcend: Does it handle unregistered systems?

It scans for personal data silos rather than relying solely on a declared inventory, which routinely surfaces systems the privacy register did not contain.
