John Rallo - PeerSpot reviewer
Offers excellent visibility into vulnerabilities and the attack surface itself
Attack surface reduction and limiting attack surface vectors are valuable features. It's helpful to isolate specific devices and get super granular with the features they offer. The visibility into the attack surface is good. It gets highly granular. I don't work on that side, but the people who do tell me they get more visibility.
Nagendra Nekkala - PeerSpot reviewer
A highly stable solution that protects computers from viruses, spyware, and hackers
ZoneAlarm doesn't require much maintenance. You only need to update the application when there are any latest updates. ZoneAlarm is deployed on-cloud in our organization. With an increase in the bring your own device concept, ZoneAlarm should be part of every device to help us make the operational work very easy. Overall, I rate ZoneAlarm a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The integration of Defender, Security Center, and the Microsoft compliance score, is the feature we use most to share the results with our clients and to create a roadmap together."
"Defender for Endpoint allows us automatic resolutions if a unit is compromised or if a user clicks a malicious link."
"The main features of this solution are that it handles everything by itself and is well integrated."
"It's very easy to scale because it comes built-in with Windows 10, and you just need to enable it. This can be done on scale using group policies or through Endpoint Manager on cloud or Intune."
"Its simplicity is the most valuable. It also has very good integration. We like it."
"The primary advantage is that you don't need to install it. It's included in the Windows 10 delivery."
"The threat hunting service is very useful for a security professional."
"Microsoft Defender for Endpoint is easy to load and it runs quietly in the background, unlike other solutions."
"The phone access scan stands out as the most valuable feature for me."
"The solution really focused on giving more security than an antivirus."
"The product's most valuable feature is the detection engine due to its ability to identify threats."
"ZoneAlarm protects all computers from viruses, spyware, and hackers."
"The solution maintains reasonable scalability."
"It is quick and easy to configure."
"It gives us security for the users' mobiles and ends up protecting us in a significant way."
"This antivirus is regularly updated, and the updates can be scheduled."
 

Cons

"Defender's cloud integration could be improved."
"The interface isn't necessarily intuitive to a nontechnical person. You can get stuck in the little endpoint security portal. Sometimes, if you uninstall a competitive product, the end user doesn't always know if it's running or if they're protected even though it's silently running. There could be a notification, widget, or something that's resident on the screen for at least a bit, especially if you're doing remote support. You want to talk them through it, but sometimes, we're not allowed to look at the PCs we support."
"Microsoft Windows Defender doesn't have a game mode."
"It would be helpful if they included XDR features, on top of the EDR functionality."
"Its price could be better."
"It can get a bit laggy sometimes. Other than that, we don't have any issues. They constantly tweak it and fix it up based on users' feedback. It has improved a lot over the past four years. Defender for Endpoint never really used to be a good endpoint security solution, but over the past couple of years, Microsoft has invested heavily in it. So, it has come a long way in all aspects of endpoint security. If they want to make it better, they should just continue investing in the current path of what they've been doing over the past couple of years."
"Updates are not coming out of preview quickly enough and it is holding back on the development of the product."
"It is using a large space in your memory all the time. While an antivirus will use some of your memory, if they could reduce the load of the antivirus to some extent that would be good."
"They should release a single update with all the necessary characteristics to avoid being in a cycle of consecutive updates."
"The solution's efficiency in threat containment and overall protection needs improvement."
"We'd like better performance of the network equipment. There are high-speed environments where an immediate response is required."
"Some of our users say that the interface is a little bit outdated for 2020, and want it to be more modern and cozy."
"ZoneAlarm should be a light application that does not take too much memory in mobile phones."
"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."
"Perhaps the primary area for potential enhancement is to make it faster, ensuring a more seamless experience while maintaining robust security features."
 

Pricing and Cost Advice

"When customers haven't deployed the solution and don't have licenses, it can be expensive to start from scratch."
"The price is fair for the features Microsoft delivers. If you want tailor-made features, you have to mix different licenses. It isn't straightforward."
"The licensing costs for Microsoft Defender for Endpoint are reasonable."
"It isn't cheap, but it's reasonable and fair."
"The solution is free with Windows."
"The licensing fee is a function of your Office 365 license. The feature set you get is a function of the license as well. There is probably an E2 version, an E3 version, and an E5 version. There are several versions, and not all features are the same. So, you might want to check what features you're expecting because you might get shocked. If you only have an E3 license, the capability isn't the same."
"Pricing for Microsoft Defender for Endpoint is competitive. Out of the bundle, you will get a lot of security, if I talk about Microsoft E5, for example, and get a lot of benefits. If the customer goes and purchases a different solution, it will cost more, so pricing for Microsoft Defender for Endpoint is quite reasonable at the moment. There isn't any challenge in terms of pricing, for example, I didn't see a customer who pulled back because of the price. Some prices could be negotiable, and sometimes, as a sales point, the two become negotiable, but they don't bill one and pull back because of the pricing. If you have an E5 license, you get everything."
"We have a bundle where the price includes all Microsoft products."
"This is a freeware product and I recommend using it."
"We have to pay a yearly licensing fee for ZoneAlarm, which is cheap."
"I rate the product pricing a seven out of ten."
"The pricing is reasonable, with a yearly renewal license costing seventy dollars."
"We use the free version of the software, but it can be upgraded to the paid Extreme Security edition."
