Have questions about this site?

What is this site?

  • This website is Hornbill's new product documentation website and is currently under development.
  • It is intended that all existing and future public-facing documentation we produce will be available to search, browse and share.
  • Hornbill's current documentation is available at Hornbill Wiki but over time this content will be migrated to this documentation site.
  • Please feel free to have a look around at any time.

Why has Hornbill created this site?

  • Hornbill's products have moved on considerably since we introduced it almost 10 years ago. At the time, the MediaWiki tool was sufficient, but we have outgrown it.
  • Our customers are more enterprise focused and more self-sufficient than ever before, so for 2023 and beyond we have established a new documentation platform and team to drive our documentation initiative forwards.
  • We are aiming to deprecate the use of Hornbill Wiki for most Hornbill related documentation.
  • We want to enable our growing partner network with product resources and information, documentation beyond our Wiki approach is required.
  • We could definitely do with some help, and may even pay for some! If you have domain knowledge and would like to help, please check out our Hornbill Docs Contributor Guide and contact the Hornbill docs team at

What will this site be good for?

  • Community contribution will be facilitated, encouraged, and most welcome.
  • High quality documentation, will be kept up to date as rapidly as our products evolve.
  • Real-time content search and discovery.
  • Articles organized into books, books into libraries, creating a more natural and logical structure to our documentation.
  • Legacy API documentation and various other documentation sources will all be consolidated into a single unified documentation system.
  • Documentation available in browser as well as printable/viewable as PDF on demand.
  • Personalized documentation experience, allowing dark/light mode, article subscriptions, social media sharing and other useful features.
  • Almost all publicly available documentation on will be open-source and available to fork on GitHub, allowing customers to derive their own custom documentation around Hornbill products should they wish to.

What is the timeline for this site?

  • We have taken the decision to publish and make available early, there is very little content at this time.
  • As and when we have completed/usable documentation, it will be published here.
  • We have a host of additional features we wish to add over time, so please watch this space.
  • We expect most of our existing documentation should be reviewed/migrated to over the coming months.
  • The documentation project will be ongoing, will continue to expand, evolve and improve day-by-day.

Subprocessors and Partner Suppliers

Hornbill partners with a number of organizations for services that contribute to the delivery of our platform service as described in our Terms of Service. Because our suppliers provide us with services that we use in order to deliver our service to our customers, our suppliers could be considered subprocessors.

What is a Subprocessor

A subprocessor is a third-party data processor engaged by Hornbill, which includes other entities from within the Hornbill Group, who has or potentially will have access to or process Service Data (which may contain Personal Data). Hornbill engages different types of subprocessors to perform various functions as set out below.

Security by Design

Hornbill designs its platform applying a “Secure by Design” philosophy. In the case of partnering with third-party contractors or subprocessors, Hornbill’s platform is designed to eliminate or minimize to the greatest possible extent exposure of customer data to subcontractor/subprocessor personnel. A good example of this would be, while we partner with data center providers we either provide our own hardware or buy/lease bare metal upon which we run our own software stack.

Contractual Safeguards

Hornbill requires all of its subprocessors to satisfy equivalent obligations as those obligations delivered under Hornbills Terms of Service, including, but not limited to…

  • Must process any Personal Data in accordance with Hornbills obligations under its Terms of Service.
  • In relation to any activity that constitutes sub-processing activity, they will only use personnel who are reliable and subject to a contractually binding obligation to observe data privacy and security, to the extent applicable, pursuant to applicable data protection laws;
  • They will ensure they provide regular training in security and data protection to personnel to whom they grant access to any Personal Data;
  • They will implement and maintain good technical and organizational measures (including measures aligned with those to which Hornbill is contractually obliged to deliver insofar as they are equally relevant to the sub-processor’s processing of Personal Data on Hornbill’s behalf) and provide an annual industry recognized certification that evidences compliance with this obligation.
  • They will promptly notify Hornbill about any actual or potential security breach; and
  • They will cooperate with Hornbill in order to deal with requests from data controllers, data subjects, or data protection authorities, as applicable.

Due Diligence

Hornbill uses all commercially reasonable steps in its sub-processor selection and partnering process in order to evaluate the security, privacy, and confidentiality practices of its subprocessors that will or may have access to or process service data. This policy does not give Hornbill Subscribers any additional rights or remedies and the details provided here should not be construed as a binding agreement.

The information here is only provided to illustrate Hornbill’s approach to selecting and engaging with subprocessors as part of providing the overall service to our customers.

Infrastructure and Data Storage subprocessors Hornbill does not operate its own data centers, instead, we partner with Tier 1 data center providers. Our computing model is either co-location or bare metal lease, in both cases, the software stack is entirely managed by ourselves.

Partner Subprocessors

Customer data is stored in an appropriate geographic data center and personal data is not transferred outside of the country or controlling region unless the prior written consent of the Customer has been obtained and one of the exceptions outlined in Hornbill’s Terms of Service applies.
