Our company was facing a problem of user complaints with network performance despite the fact that we used Cisco ASA and Cisco IPS. When we scanned the mail server with antivirus we found a lot of threats that couldn't be treated, so we need to use IronPort. Cisco IronPort mail security was very helpful by blocking threats, viruses, worms and Trojans from attacking the mail accounts and user PCs.
Room for Improvement:
-Added cost and delay to the network traffic, but performance did remain stable.
-Requires knowledge and operation time to manage an added security device to the network devices besides IPS and ASA.
Cisco IronPort is Cisco's new network access controller (NAC). Cisco IronPort email and web security products are used online with the firewall Cisco ASA and Cisco IPS to filter attacks, threats, phishing and data loss.
