Room for Improvement: Cisco Secure Email requires better integration with third-party reporting tools and enhancements in CLI management. Users have noted challenges with rule-setting, desiring user interface improvements and better hardware reliability. Cisco Secure Email Threat Defense could enhance its collaboration with other tools, improve intuitive reporting, and develop a smarter search function. Both products would benefit from better phishing protection and additional sandboxing, along with cost reductions for broader accessibility.

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.

Senior Cybersecurity Engineer at a financial services firm with 11-50 employees
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

"The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"The most valuable features are protection against ransomware and spam."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"Administration of the email domains and custom filters are easily done via the web interface."
"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
More Cisco Secure Email pros
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"Secure Email Threat Defense's scalability is good."
"The solution is stable."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"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."
"It has an efficient email filtering feature."
"I highly recommend it as one of the best choices."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

Cons

"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The user interface of the Email Security Gateway should be improved."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"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."
"The pricing needs to be reconsidered or enhanced."
"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 primary areas for improvement are the pricing and the complexity of deployment."
"Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way."
More Cisco Secure Email cons
"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."
"We encounter issues while searching for missing emails."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The pricing could always be better."
"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."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"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."
More Cisco Secure Email Threat Defense cons
 

Pricing and Cost Advice

"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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."
"It is a super big router that costs a few hundred thousand dollars."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"The price is significantly high."
"The solution is expensive."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
More Cisco Secure Email pricing and cost advice
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"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."
