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.

Pricing and Cost Advice

"The solution should reduce the cost."

"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."
