It has the IMS engine, Intelligent Multi-Scan engine, and it does a good job, right out-of-the-box, of blocking the vast majority of things that should be blocked.

Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number...

We like the in-built features, like the email filtering based on the IP and domain. Cisco has its own blacklisted domains and IPs, which is very good. This filters around 70 percent of emails from spam, and we are seeing fewer false positives with this.

The user interface was quite friendly, it was quite easy to use, unlike some other Cisco products. Anybody could use it. You don't have to be familiar with IT to be able to handle navigating it.

We're consolidating two to three arrays down to one which means that our data center footprint has decreased by like 90%. So we're saving 90% of our space, and it also is much better on power and everything else in our data center. And on top of that, the performance is much, much better than our older arrays.
The most valuable feature is the performance and compression. The most useful tool is CloudIQ.

There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system.

Users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification.

At one point, there was a zero-day attack. The Cisco appliance detected it and stopped it, helping us out. We avoided the attack and potential damage.

It integrates with Active Directory and we can limit specific users to using specific applications.

It would be nice to have an easier way to check on the health of the system, how stressed these appliances are. Sure, you can do it, but it would be helpful to have an easier way to do it, maybe even at a glance.

We have occasionally had hardware problems because we are using an appliance-based solution, but that might change. We may consider going to virtual systems.

The solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working.

We didn't get any malware, but a few phishing emails, maybe one or two, slipped in.

We've had a couple of little things come up, but for the most part, they've been pretty stable.

They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters.

One of the things that Cisco could improve on with IronPort is the support. Cisco doesn't really have enough engineers who have full, hands-on knowledge of IronPort. Knowledge of it is not something you can find easily compared to other security appliances.

The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user.

I would like them to add some clustering or high availability features.

The hardware is not up to the mark. Two to three times a year we have complete downtime.
