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.

Improved email threat visibility and security posture through adaptive reputation and analytics
I have experience with Cisco and other vendors like Sophos. I have more than 10 years of experience in this field. I worked with the Adaptive Reputation Management feature of SonicWall. Machine learning plays an important role in updating threat intelligence, particularly with SonicWall. The pricing for SonicWall Email Security is reasonable and budget-friendly. My overall rating for SonicWall Email Security is 8 out of 10 because, apart from the areas that need improvement, it was overall good.

Quotes from Members

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

Pros

"Secure Email Threat Defense's scalability is good."
"It's very easy to deploy and configure."
"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 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."
"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."
"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."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"There are no wasted extras and the interface is really simple, so even if you don't have an IT background you can understand the working procedure and how systems are monitored."
"The most valuable feature of SonicWall Email Security is the blocking of emails using keywords. If there are any particular keywords in the subject, that we want to block from receiving from a particular person we can do it. Additionally, the blocking of emails is easy. we can release that one and we can block some of the keywords also like that."
"SonicWall Email Security has benefited the company by preventing attacks, protecting us from threats such as ransomware and phishing, and notifying the IT team when phishing emails have been blocked."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"It is a very scalable solution."
"There are no wasted extras and the interface is really simple."
"We always get ROI from the product we are using; it is completely flexible and acceptable according to our security requirements over the last four years and currently."
"This solution has been really good for us and I recommend using it."
 

Cons

"The search area has room for improvement."
"We encounter issues while searching for missing emails."
"The physical appliance has been discontinued, although the platform still exists."
"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."
"This solution could be improved by integration with Sandbox."
"The solution is a bit expensive. It could be cheaper."
"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."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Updates could be released more frequently."
"I am not satisfied with phishing protection, as it falls completely under the email domain security."
"Other than that, really I think the features are perfect, but attachment controls are so important it hurts the usability of the product."
"SonicWall Email Security is scalable, but the price per license is expensive."
"There could be definition updates included in the subscription."
"The technical support from the company is not always very good at solving issues, but they offer access to a good community of users where problems are easily solved."
"The after-sale support needs improvement. They don't have representation in my country."
"The pricing could be improved."
 

Pricing and Cost Advice

"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"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 platform offers a yearly license."
"We have a two-year license subscription and the price is very high."
"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."
"I rate the application’s pricing a five out of ten."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
"Our customers purchase the solution's yearly license."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
