Client Case Studies
By far the best proof is experience.

Castelain has worked with some of the largest organisations and government departments within the Asia Pacific region, and across multiple industries.
These clients have mission critical, high availabilty systems that we have helped to keep online and safe from intrusion. We have designed and implemented highly useable but secure ways of authenticating and managing users – both internally, as well as outside the firewall, extending into our clients' customer bases.
