Technical Specifications

Provenance

Avius Surveys and Avius Optimus software is developed by Avius Ltd in the UK, no part of it is outsourced or subcontracted.

The Avius servers have been built and are maintained by Avius Ltd.

The Avius Surveys and Avius Optimus software have been developed by Avius Ltd in the UK and uses standard industry software such as Qlik, Microsoft, Mongo etc.

Avius Surveys uses some commodity third party components in the Avius Surveys application and Avius Optimus to provide support for hardware scanners, data parsing, data storage etc.

Written comments in Avius Surveys and Avius Optimus responses may be processed by WebPurify and Google Translation APIs depending on customer preference to aid in filtering out profanity and translating comments into different languages. The comments are not sent with any additional survey response data and Avius Ltd does not provide a way to identify the customer or site.

 

Security

Avius Surveys devices are configured with PIN codes to deter theft and prevent customers accessing anything but the Avius Surveys application functionality. Once a survey response has been sent to the servers, the response is deleted from the local device’s storage.

Avius Surveys devices that are reported stolen can often be remotely locked and tracked.

Data transferred to and from the Avius Surveys and Avius Optimus servers is via HTTPS and is TLS/SSL encrypted. Passwords are passed through a strong one-way hashing algorithm and the original password information is not stored.

The data is stored on dedicated servers in a well-established tier 2, UK based data centre, where bio-metric credentials are required to gain access to the building.

 

Connectivity design

Avius Surveys devices connect to the internet using either Wi-Fi or Cellular connectivity. The internet connection is used to connect to our servers which are hosted in a data centre in the United Kingdom and to the device manufacturer’s notification, application and operating system update services.

Each Avius Surveys device once setup can operate without internet connectivity by storing completed survey responses locally on the device. This is limited only by the storage space available on the device.

Whilst operating offline, the Avius Surveys device will not receive updates to the survey, theme, Avius Surveys application or device operating system.

 

Network traffic

Once an Avius Surveys device is set-up and running, the most frequent traffic will be survey responses. These will occur whenever a customer completes a survey on the device.

Health checks run every 30 minutes (this is customisable) for the device to report its status to Avius Surveys support. Occasionally the Avius Surveys application will be updated to add new functionality or resolve issues.

When requested by the customer, their survey or theme will be updated and these changes will be pushed to the Avius Surveys device.

Avius Surveys devices may also receive operating system updates from the device manufacturer designed to maintain the performance and security of the underlying platform. The application may leverage new functionality provided by these updates from time-to-time, this will require the customer to run the device manufacturer’s update.
