Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. 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. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

I do not work with Cloud Secure Edge, CSE, or SMA apart from SonicWall NSA. I am not satisfied with phishing protection, as it falls completely under the email domain security. The customizable policy configuration does not help to tailor email security overall because our systems are not integrated with SonicWall Email Security. We are not using reporting and analytics because it requires completely different software. While all required features are available in SonicWall Email Security for SMBs and startups, we lack analytics features. They provide an option to purchase a complete separate product for analytics, but despite initially having purchased the paper license, due to technical limitations or changes, we cannot use that product. Now they require additional fees to access the analytics feature.

Quotes from Members

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

Pros

"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."
"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."
"This solution is easy to use."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"I highly recommend it as one of the best choices."
"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."
"Secure Email Threat Defense's scalability is good."
More Cisco Secure Email Threat Defense pros
"The anti-spam aspect of the solution is its most valuable feature."
"The product is easy to manage in terms of configurations."
"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 uses multi-layer cloud security."
"The pricing for SonicWall Email Security is reasonable and budget-friendly."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"This solution provides very good email security that protects us against spamming and malware."
"SonicWall Email Security uses multi-layer cloud security."

Cons

"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 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."
"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."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"We encounter issues while searching for missing emails."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
More Cisco Secure Email Threat Defense cons
"The reporting needs improvement."
"The pricing could be improved."
"The platform's control panel needs enhancement."
"The protection level for email security isn't 100%. I'm still getting some spam and junk mail."
"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"
"The pricing could be improved."
"They should integrate the solution with third-party platforms."
"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."

Pricing and Cost Advice

"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."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
"We have a two-year license subscription and the price is very high."
"The platform offers a yearly license."
"I rate the application’s pricing a five out of ten."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"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."
"Our customers purchase the solution's yearly license."
