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.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

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

Pros

"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"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 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."
"The most valuable features are protection against ransomware and spam."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"It is a user-friendly product."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
 

Cons

"I would like to see features like AI since it is currently an area that the product lacks."
"The user interface is a bit complex."
"The scalability must be improved."
"Licensing is quite complicated for a number of customers, including ourselves."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"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."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"Pricing depends on your environment and which model you want to buy."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"The pricing is good."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"It is a reasonably priced solution."
"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."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
