• Independent networks for backups, management and public services ensure the highest levels of security and performance by segregating traffic on physically separate networks.
• 99.99% Core Network Service Level Agreement

*In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe.

• Back up is to a dedicated server in a Tier 4 data centre in the North Island to accommodate additional archiving, data management and disaster recovery.
  

• Private Data Centre – invited, escorted access only
• No signage, nondescript building
• Single entry and exit point, using biometric devices and man-trap access
• Network cameras monitoring and recording all movement – no blind spots
• Perimeter fencing encompasses the data centre with CCV (closed circuit video) surveillance cameras recording all entry/exit points and open areas
• Security patrols nightly at random times to ensure the location remains secure. After hours access to the location is via keypad entry only

• Segregated fire-rated power room, independent biometric access

• The server is patched and all applications kept-up-to-date
• The database does NOT listen for remote connections
• Exess review security on a regular basis and act promptly on any identified issues
