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

"The tool has a DLP solution which we can implement. Its database is updated regularly."
"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."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"It's a bit easy to handle Cisco Secure Email; it's not that difficult. For the logs, which are in PDF format, it's not hard to read them. We don't need Wireshark much to analyze the logs."
"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."
"It blocks bulk marketing messages, graymail, spam, and provides advanced malware protection."
"It is stable and reliable."
 

Cons

"We cannot manage multiple devices from a single UI."
"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."
"The reporting functionality needs to be improved."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"The tool's pricing can be improved."
"I am not satisfied with the solution's reporting and logging."
"I have some frustrations with the user experience in the interface, specifically with regard to making a list of people for whom I want to allow email access."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The price is significantly high."
"The licensing was all transferred."
"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."
"The pricing is good."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"There were no other costs in addition to the standard licensing fees."
"Cisco Secure Email is expensive, but we get what we pay for."
"Pricing depends on your environment and which model you want to buy."
