Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

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

"The email policy configuration options in Microsoft EOP are satisfactory."
"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."
"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."
"The initial setup was easy. The configuration process is very straightforward."
"It's all running in the backend, so it doesn't affect the app functionality."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"Overall, I think it's really a great product."
"We can migrate seamlessly without any disruptions to our operations."
"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."
"There are no wasted extras and the interface is really simple."
"This solution has been really good for us and I recommend using it."
"The pricing for SonicWall Email Security is reasonable and budget-friendly."
"It is a very scalable solution."
"Behind the reason we chose SonicWall for my company is it has excellent packet analysis of normal and SSL encrypted traffic, application intelligence visualization and control, multiple Gigabit Ethernet LAN and WAN ports, flexible configuration and redundancy options."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"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."
 

Cons

"The product's end-of-life cycle could be extended."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"Microsoft Exchange Online Protection is quite a difficult product."
"The solution needs to improve its backup."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"There could be definition updates included in the subscription."
"Other than that, really I think the features are perfect, but attachment controls are so important it hurts the usability of the product."
"The reporting needs improvement."
"Policy deployment could be time consuming and represents an area for improvement in SonicWall Email Security."
"Previously, we had an issue with a faulty appliance and had to wait over two weeks for a replacement."
"I am not satisfied with phishing protection, as it falls completely under the email domain security."
"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."
"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."
 

Pricing and Cost Advice

"The price of Microsoft Exchange Online Protection is reasonable."

"Online Protection is fairly expensive."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"It is a low-price solution."
"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."

"We have a two-year license subscription and the price is very high."
"I rate the application’s pricing a five out of ten."
