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

"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."
"I can customize the configuration and policies."
"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"Cisco IronPort mail security was very helpful by blocking threats, viruses, worms and Trojans from attacking the mail accounts and user PCs."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"It is a user-friendly product."
"The security features are valuable."
"The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution."
"Cisco's technical support is very good."
"It's very easy to deploy and configure."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"I highly recommend it as one of the best choices."
"On ease of use, it rates very high."
"It has an efficient email filtering feature."
 

Cons

"The user interface of the Email Security Gateway should be improved."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"We use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"The area of license renewal should be improved. We normally renew our license every year. There is a feature called smart licensing, and I switched from the legacy mode to the smart licensing mode because of what I thought smart licensing does. I thought it would make licensing renewal seamless and very swift, but ever since I've switched to smart licensing, each time I want to renew my license, it is a whole lot of headache. The process is not smooth, and I had to keep calling Cisco TAC to see how the issue can be resolved. At one point, I wanted to revert back to the legacy mode, but I can't revert. Once you switch from the legacy mode to the smart licensing mode, you can't revert. They should improve on the visibility of the smart licensing mode so that it can indeed be smart and easier to use for the license renewal every year. That is one challenge."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"This solution could be improved by integration with Sandbox."
"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."
"The solution is a bit expensive. It could be cheaper."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The pricing could always be better."
"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

"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"It is an expensive product. I rate its pricing an eight or nine."
"It is a relatively expensive option compared to other alternatives."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"The pricing is good."
"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."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
