Openera runs on enterprise-grade cloud server infrastructure provided by Amazon AWS. The full system, data and documents are backed-up each night. This ensures that in the event of any service failure or accidental deletion of data that it can be easily retrieved from the previous day back-up.
The service operates using 256bit SSL encryption. This means that all traffic to and from the server is encrypted and secure. This is a similar level of security typically utilised for banking and financial transaction systems and has been implemented to ensure that all data and documentation is secure.
