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.

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."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"Online Protection's most valuable feature is its admin interface."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The product's most valuable feature is third-party integrations."
"It offers great security against malware and other threats."
"ZoneAlarm provides us with very good security and we are using both of the modules, including antivirus as well as firewall features, and it is very easy and stable for us."
"The product's most valuable feature is the detection engine due to its ability to identify threats."
"The phone access scan stands out as the most valuable feature for me."
"I strongly recommend ZoneAlarm as a simple but efficient solution, especially if your organization doesn't have a dedicated budget for providing a security solution for BYOD devices."
"It is quick and easy to configure."
"User friendly design and interface"
"The solution maintains reasonable scalability."
"It gives us security for the users' mobiles and ends up protecting us in a significant way."
 

Cons

"I think the implementation could be more streamlined."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The solution must improve the user experience."
"The tool's classification for bulk email is cumbersome."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The price could be lower."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"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."
"I have used it in the past for personal desktops and for systems at small startups, but I would not recommend it as an enterprise level firewall security solution."
"I would like it to be integrated with the Check Point centralization solution like Infinity Portal. It would be great to be able to manage it through the same website."
"Currently, the client is only available for the Windows Operating System but it would be good if it were released for Mac OS as well."
"The solution's efficiency in threat containment and overall protection needs improvement."
"ZoneAlarm should be a light application that does not take too much memory in mobile phones."
"We'd like better performance of the network equipment. There are high-speed environments where an immediate response is required."
