  • ASA is our VPN concentrator. The client and server are very stable and very easy to use
  • ASA also offers Intrusion Prevention, to an extent. This is also very useful for an improved security posture for a small company
  • ASA allowed us to scale very quickly. We could onboard clients, partners, and consultants and give them a great onboarding experience as well
  • Administrative costs with ASA are low. It's very easy to administer.
Cons
  • For small companies that require DLP, ASA could add a basic DLP system
  • ASA has an easy web administration screen. It's look-and-feel could be improved
  • ASA could develop and/or promote agentless VPN access
