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

"You are never secure without some solution from Cisco."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"The product's initial setup phase was easy."
"From a functionality perspective, the platform is great."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"Apart from the improvement needed to the filters, it was all good."
"It provides good IT assistance."
"Overall, it is a very good product, and I'm very happy with it."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The product offers protection, email security, anti-spam, and antivirus."
"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"This solution is easy to use."
 

Cons

"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"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."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"In future releases, I would like to see two main improvements come to mind. First, the current solution requires maintaining two separate operating systems for FTD, which can be cumbersome. I'd love to see a single operating system for the FTD box."
"The area of license renewal should be improved. We normally renew our license every year."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"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."
"The user interface is a bit complex."
"The search area has room for improvement."
"The pricing could always be better."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"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."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The physical appliance has been discontinued, although the platform still exists."
"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 behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
 

Pricing and Cost Advice

"The licensing was all transferred."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"It is an expensive product. I rate its pricing an eight or nine."
"The pricing is good."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"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."
