Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"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.""Because we scan products, and there is a lot of critical data, security is very important in these cases.""It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP.""It integrates with Active Directory and we can limit specific users to using specific applications.""I can customize the configuration and policies.""It blocks bulk marketing messages, graymail, spam, and provides advanced malware protection.""The most valuable features are protection against ransomware and spam.""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."

Cons
"I would like them to add some clustering or high availability features.""The initial setup was complex because I have two sites with physical clusters.""The hardware is not up to the mark. Two to three times a year we have complete downtime.""The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI.""I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services.""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.""We didn't get any malware, but a few phishing emails, maybe one or two, slipped in.""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."

Pricing and Cost Advice
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000.""In addition to the standard licensing, there is a cost for SMARTnet as well.""Pricing depends on your environment and which model you want to buy.""Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user.""The license was not per user, the license model was per feature. You could choose anti-virus, anti-spam, etc. It was feature-based and charged yearly.""There were no other costs in addition to the standard licensing fees.""We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point.""It is not that costly. We pay for the solution through a contractor and pay an annual fee."
