The security of your data is our number one priority.  The datacenter in which we host our virtual servers has achieved ISO 27001 certification and passed SAS70 Type II audits.  Multiple HIPAA-compliant web applications are hosted in the datacenter.  Our search applications use a mix of declarative and programmatic authentication to secure access.  Access passwords are a number-letter mix and at least eight characters long to prevent brute-force attacks.  We are constantly considering ways to improve application security.
