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

"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."
"The most valuable feature is the different content filters we are using, such as DKIM."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"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."
"Cisco Secure Email's most valuable is email certification."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"Administration of the email domains and custom filters are easily done via the web interface."
"It is stable and reliable."
 

Cons

"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."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"I am not satisfied with the solution's reporting and logging."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"The primary areas for improvement are the pricing and the complexity of deployment."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"The solution could be less expensive."
 

Pricing and Cost Advice

"There were no other costs in addition to the standard licensing fees."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"Pricing depends on your environment and which model you want to buy."
"It is an expensive product. I rate its pricing an eight or nine."
"The solution is expensive."
"As per market availability, this solution is more expensive than other vendors."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"There are additional fees for adding features."
