Netflow v9, but it's not similar to netflow v9 that most routers exports, could cause issues with certain collectors It also has a fail-login delay block, to protect from brute-force or mis-used from failed logins

  • Fortinet fortiguard is quite awesome and very mature and advanceīoth unit allows for common management protocols with the fortinet allowing you to changing ssh/telnet ports and restricting access to a user.
  • IDS protection is part of the appliance hardware ( no add-on card/module, no special licensing or restrictions ).
  • requires some IDS engine or card and managed separately & possible license restrictions.
  • Supports for custom rules, but not very user friendly.
  • Duplicates can be installed with no warning, causing issues when auditing policies Policies are built between zones to zone or interface to interface similar to juniper. Uses a ACL approach for the ingress/egress interface and no other direction is requiresĬisco also eliminates duplicate by disallowing the entry of duplicate acl lines within a single access-list Getting better, but ipv6 support is still quite new in the ASA lineupīeen ipv6 enabled for at least 6+ years now, but we still don't have OSPFv3 authentication :(
  • one big configuration file, with no separations for the unique vdoms.
  • by default all interfaces are part of the vdom root, so enabling vdom support does not drop any interfaces/policies or configurations if your going from a vdom-less to vdom-concept.
  • Vdom supports all open routing protocols ( rip,ospf,bgp,is-is), and not as restrictive.
  • Supports a minimum of 10 vdom ( virtual domains ).
  • Just the pure enabling of the multi mode context feature, requires a reboot.
  • Also the context configuration files management, is awkward and confusing, the first time that you deploy the configurations files.
  • And then in multi context mode, your limited to just OSPF or EIGRP only (ipv4) and no dynamic routing protocols for ipv6
  • Context in ASA don't support any remote-access vpn, and until recently no dynamic routing protocols.

  • Cisco contexts are very restrictive, typically you are limited to 3-4 contexts ( except a ASA5505 no contexts available ).
  • Supports blackhole routes via null-interface Typically one relies on the next-hop device, or just ACL'ing off the traffic Only has 1 or 2 license types ( vdom and forticlients ) Licensing is not additve ( e.g if you have 25 vpn peers and want 25 more, you have to buy a 50 vpn peer license and can't buy a 25 peer license ) In this post we will go over some of the difference between these 2 models of firewalls.Ĭisco has a whole gamlet of licensing that can be applied, and it can be quite confusing
