Provides comprehensive threat protection with suggestions for modernizing controls
I use the email gateway as the core of the email exchange between the Internet and our domain. The email gateway serves as the email exchanger The product offers protection, email security, anti-spam, and antivirus. It includes threat intelligence with advanced malware protection and many…
Swapnil Kulkarni - PeerSpot reviewer
Has consistently supported security needs for mid-sized teams with affordable deployment
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

"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."
"It's very easy to deploy and configure."
"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."
"The product offers protection, email security, anti-spam, and antivirus."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Secure Email Threat Defense's scalability is good."
"The solution is stable."
"Setup was easy. It took about 30 minutes."
"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."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"The anti-spam aspect of the solution is its most valuable feature."
"The most valuable feature is that it protects from spam."
"There are no wasted extras and the interface is really simple."
"This solution provides very good email security that protects us against spamming and malware."
 

Cons

"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"The pricing could always be better."
"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."
"We encounter issues while searching for missing emails."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The physical appliance has been discontinued, although the platform still exists."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
"A lot of spoofed emails are still coming to the end-user, so the configuration for this option needs to be improved."
"The platform's control panel needs enhancement."
"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"
"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."
"They need well-trained partners in Nigeria."
"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."
"They should integrate the solution with third-party platforms."
"The reporting needs improvement."
 

Pricing and Cost Advice

"It is expensive compared to other vendors."
"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."
"The feedback from vendors and customer is that it is expensive."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"Our customers purchase the solution's yearly license."
"The platform offers a yearly license."
"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."
"We have a two-year license subscription and the price is very high."
