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.

Security suite has protected individual devices from threats, while installation and network features require improvements
BIG-IP is actually the LTM, Link Load Balancer, which comes with ASM, meaning Application Security Module. It consists of multiple modules, such as ASM, SWG, and a domain DNS manager. ZoneAlarm allows defining trusted and public networks, which helps maintain security in public Wi-Fi environments. It offers comprehensive protection, securing PCs against threats. Users do not experience any system slowdowns while scanning. Harmony Browser protects all your browsing activity and is bundled with Harmony Endpoint and Harmony Connect. It provides a small but effective security layer and sometimes comes packaged with the larger Harmony suite.

Cons

"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
