Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

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 tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"Anti-Spam and Advanced Malware Protection are the most valuable features; they provide protection from most email threats and we also have the option to block Zero-day attacks."
"There are a lot of filters for scam emails and things like that work out of the box. You can also use the antivirus features. I like its features."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"The most valuable feature is the different content filters we are using, such as DKIM."
"It provided a platform to sell a service to customers."
"It integrates with Active Directory and we can limit specific users to using specific applications."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"A stable solution."
"Go for it! I think it's an excellent product with great technical support."
"Ability to create your own content-filtering policies with relative ease."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
 

Cons

"The product's GUI for the dashboard needs improvement."
"They can do it better with web links, with the URLs."
"The initial setup was complex because I have two sites with physical clusters."
"There could be additional DLP functionality for it."
"Licensing is quite complicated for a number of customers, including ourselves."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"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."
"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."
"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"It is a relatively expensive option compared to other alternatives."
"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."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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."
"As per market availability, this solution is more expensive than other vendors."
"The solution is expensive."
"There are additional fees for adding features."
