NaySan @ Suraj Verma - PeerSpot reviewer
Has effectively blocked sophisticated attacks and malicious activities while providing excellent support
Microsoft Defender for Endpoint is very good, but one suggestion is that in some products, we may need to configure security-related settings, whereas Microsoft Defender for Endpoint works completely differently, providing automatic recommendations and actions that we may need to perform ourselves. Regarding the pricing of Microsoft Defender for Endpoint, during the last three years, we set up the product and sold it, but we faced difficulties because Microsoft pricing is always the same. For example, whether I purchase Microsoft Defender for Endpoint for one year or for the next three years, the pricing remains constant with no discounts available. In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment. Microsoft should consider this option to remain competitive, but otherwise, everything else is fine.

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

"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."
"We apply the DLP policies across a range of endpoints and it is very accurate when reporting vulnerabilities, including those in email attachments."
"We have liked the fact that it comes with Microsoft Windows 10 and it is constantly updated with all new virus definitions. It is also updated with new security features on a regular basis."
"There are a couple of features, such as isolating the devices or connecting the device and connecting live response."
"The integration with all variations of Microsoft Defender, for Endpoint, 365, and Cloud is valuable."
"It has Kusto Query Language (KQL), so we can use our own queries to find anything."
"It is stable and very easy to use."
"The antivirus is the most valuable feature."
"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."
"Personally, I find the Game Mode of the Firewall very useful."
"The solution really focused on giving more security than an antivirus."
"ZoneAlarm protects all computers from viruses, spyware, and hackers."
"It is easy to use through interfaces and easy to configure each of the customizations we created based on the characteristics that we wanted."
"It is quick and easy to configure."
"The phone access scan stands out as the most valuable feature for me."
 

Cons

"The price, in general, could always be a little bit cheaper."
"Right now, there's a portal for Azure, portals for Microsoft Office, and portals for endpoints. It would be good to have only one portal and integrate everything."
"On the Mac OS platform, there is no parity between Windows and Mac OS. The solution is very feature-rich and very well-integrated into Windows, and I guess baked into Windows 10 and Windows 11. Whereas, on the Mac OS platform, there is still some work there to give it a more feature-reach platform."
"Features like device inventory continue to lack essential workstation drill-downs showing the entire device information with the least effort."
"The application control feature requires improvement."
"Threat intelligence has the potential for improvement, particularly by integrating more sources."
"I think Microsoft needs to improve some of the security aspects of Defender. The email part, in particular, needs to be improved in terms of security effectiveness."
"Its user interface (UI) can be improved. Currently, in the console, you have to dig down for certain things. They've got many different layers to get to things instead of having it all on the surface. You have to go three folds lower to get to specific functionality or click a particular option. It would be good if we can manage the console through menus and instead of three clicks, we can do things in one click. They need to change the UI and work on it in terms of a better user experience."
"ZoneAlarm should be a light application that does not take too much memory in mobile phones."
"Perhaps the primary area for potential enhancement is to make it faster, ensuring a more seamless experience while maintaining robust security features."
"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."
"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."
"They need to update and improve the features available for Mac."
"We'd like better performance of the network equipment. There are high-speed environments where an immediate response is required."
"They should release a single update with all the necessary characteristics to avoid being in a cycle of consecutive updates."
"The support is not always so effective."
 

Pricing and Cost Advice

"The solution is included with Microsoft Windows."
"This solution is part of an enterprise license we have."
"For me, the pricing is very good, but for management it's very expensive. Other solutions are less expensive. But when I present all the information and all the reports they say, "Well, it's expensive, but the cost-benefit is very good.""
"Microsoft Defender for Endpoint is an expensive solution."
"Microsoft Defender for Endpoint is more affordable compared to some other endpoint solutions."
"Even if you are not registered as a not-for-profit, the offering that they have is definitely worth consideration. This is in the sense that the E5 stack just gives you so many benefits. You get your entire productivity suite through Microsoft 365 apps. You get all your security and identity protection. You get the Defender for Endpoint and Defender for Identity. You get the cloud access security broker as well. You get Azure Active Directory Premium P2, which gives you so many good things that you can configure and deploy. You don't have to configure them on day one, but you have access to so many different tools that will protect your data, security, endpoints, and identities that you could build out a security strategy 18 months long, and slowly work your way through it, based on what you have available to you through your license."
"Pricing can always be lower."
"The nice thing about Defender and Sentinel is that the cost is based on the data logs that you ingest from the Defender endpoints and data connectors. I don't have to buy a 25- or 50- or 1,000-user or enterprise license. I can buy one license at a time."
"We have to pay a yearly licensing fee for ZoneAlarm, which is cheap."
"This is a freeware product and I recommend using it."
"I rate the product pricing a seven out of ten."
"We use the free version of the software, but it can be upgraded to the paid Extreme Security edition."
"The pricing is reasonable, with a yearly renewal license costing seventy dollars."
