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.

System Administrator at Ador Powertron Ltd.
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.
