High security needs/high IT expertise

This practice does not only grant Internet access to all networked computers, but it does also provide web

services (e.g. practice website, online appointment system etc) from within the practice premises, and/or it

uses the Internet for virtual private networking VPN – e.g. a link between branch surgeries). This practice

will probably operate its own mail server.

However, even practices with lesser security demands would benefit from firewalls of this category. Both

software products and appliances in this category often have additional features, such as more than one

WAN (Internet) port, allowing you to balance multiple broadband connections for better performance and

failover capabilities.

Recommendation: Dedicated customised gateway computer with ‘DMZ’ and VPN tunnelling capabilities

and stateful packet inspection firewall. It is strongly recommended that you choose products with good

commercial support unless you have outstanding IT security expertise within your staff. Alternatively, more

sophisticated (and expensive) firewall appliances may be suitable. Choosing a product with load balancing/

failover capabilities over at least two WAN (Internet) ports is highly desirable if you depend on availability

of Internet services and can afford multiple ISP services.
