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.

Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job."
"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."
"The system enables end users to manage their own whitelists/blacklists."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"The technical support from Cisco is perfect."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"This solution is easy to use."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"I highly recommend it as one of the best choices."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"It's very easy to deploy and configure."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
 

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."
"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 primary areas for improvement are the pricing and the complexity of deployment."
"I am not satisfied with the solution's reporting and logging."
"The tool's pricing can be improved."
"I would like them to add some clustering or high availability features."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change. We may consider going to virtual systems."
"The physical appliance has been discontinued, although the platform still exists."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The solution is a bit expensive. It could be cheaper."
"This solution could be improved by integration with Sandbox."
"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
 

Pricing and Cost Advice

"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"The product's price falls on the higher side when compared to the other products on the market."
"The pricing is good."
"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."
"The price is significantly high."
"I rate the pricing a ten out of ten on a scale where one means it is less cost-effective, and ten means it is the most cost-effective solution."
"The solution 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."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
