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

"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."
"It provided a platform to sell a service to customers."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"The most valuable features are protection against ransomware and spam."
"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."
"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."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"The pricing needs to be reconsidered or enhanced."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"There could be additional DLP functionality for it."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
"The product's GUI for the dashboard needs improvement."
"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 scalability must be improved."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"The licensing was all transferred."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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 expensive, but we get what we pay for."
"Pricing depends on your environment and which model you want to buy."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
