Threat intelligence with fast attack detection enables comprehensive email protection
In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam. This could result in users not opening genuine emails. We have highlighted this to Cisco because sometimes phishing or marketing campaigns, which are genuine, are incorrectly flagged as spam. The solution should better analyze the actual content rather than only focusing on the email header or origin.

Quotes from Members

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

Pros

"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"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..."
"Cisco Secure Email's most valuable is email certification."
"It has the ability to tell us, after an email has been delivered, where else it went, once it got inside. Maybe it's something we wanted it to stop and it didn't stop it, but it notified us later that it was something that it should have stopped. It can give us a trajectory of all the other places that it went internally and it can tell us what files were transferred as well."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"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."
"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."
"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job."
"It is stable and reliable."
 

Cons

"I would rate the stability a six out of ten. We had multiple issues with the stability."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"The pricing needs to be reconsidered or enhanced."
"We cannot manage multiple devices from a single UI."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"My opinion on the licensing of this solution is that it is a mess that needs sorting out. I am not particularly bothered by pricing as I administer it and make recommendations for people to buy or not to buy."
"The solution could be less expensive."
 

Pricing and Cost Advice

"As per market availability, this solution is more expensive than other vendors."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"The price is significantly high."
"There were no other costs in addition to the standard licensing fees."
"The solution is expensive."
"It is a reasonably priced solution."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
