Why Upgrading from the ISA to the TMG Firewall is a Good Thing

imageOK – I understand. The ISA 2004 or 2006 firewall you’re using has been doing a great job and has been rock solid over the years. Why should you upgrade that ISA firewall to TMG when the ISA firewall has been working like a champ all these years?

There are several good reasons – some of them include:

  • TMG firewalls have built in URL filtering
  • TMG firewalls support outbound SSL bridging, which enables SSL inspection (which prevents malware from hiding from the firewall)
  • TMG firewalls include the Network Inspection System (NIS), which enables robust network level IDS/IPS
  • TMG firewalls include strong web antimalware capabilities right out of the box
  • TMG firewalls are native 64 bit firewalls, which makes them more scalable, more stable, and more secure than 32 bit solutions
