6.5
Symantec Endpoint Security's customer service is efficient, while technical support responses vary, affected by locality and language issues.
The level-one support seems disconnected from subject matter experts.
I rate Microsoft support 10 out of 10.
Due to our size, we don't have access to direct technical support, but the knowledge base, Microsoft Learn, and the articles available are really good.
In some cases, it rates as high as ten out of ten, while in others, it can be as low as eight.
There is no support in the German language, which is a problem for many public tenders.

We managed to scale it out in a short amount of time, with two months of planning and three months of implementation on 10,000 computers.
Microsoft Defender for Endpoint is scalable enough to handle various devices across environments, whether they are laptops, Android devices, or operating in hybrid environments.
Compatibility is its main feature.
Symantec Endpoint Security is quite scalable, and it is very important for large clients.

Defender for Endpoint is extremely stable.
I have encountered issues where I had to uninstall and reinstall the product on end users' computers to view the logs again.
Previously, we used to have multiple servers such as GUP servers and numerous servers for pushing updates, but we reduced it and transitioned almost 30,000 devices to CrowdStrike, which was easy to manage.
 

Room For Improvement

Microsoft Defender for Endpoint faces interface complexity, slow detection, high CPU usage, integration issues, and seeks improvements in multiple areas.
Symantec Endpoint Security faces challenges with virus detection, resource consumption, complex management, integration, and needs improved threat protection and support.
Repeated interactions are necessary due to Level One's lack of tools and knowledge, hindering efficient problem-solving and negatively impacting our experience with Microsoft support.
In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment.
We use Microsoft partners to help govern the platform, and as part of an alliance, we want to gather data from each tenant and combine them for a complete view.
Device management is not very good and I am not enabling it in my organization due to security reasons.
I would like to see improvements in the scanning part of the solution, specifically to enhance the CPU and hard disk usage during scanning and updates to prevent disruption during work hours.
It is cumbersome to use, particularly in handling firewall management.
 

Setup Cost

Microsoft Defender for Endpoint offers flexible pricing, making it competitive and cost-effective compared to standalone security products.
Symantec Endpoint Security provides a reasonably priced solution with discounts for specific sectors, offering value despite cheaper alternatives.
Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs.

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.
Kumbesh Rajagopal - PeerSpot reviewer
Management becomes easier with minimal complications, but improvement in support tools needed
Regarding areas of improvement for Symantec Endpoint Security, there are many changes, and the support portal tool is complicated compared to other tools. When trying to get service from Symantec, the process is complex. I'm not sure whether it's because of my project or something else. Though it is easy to manage, easy to get, easy to install, and works efficiently for managing policies, we faced a significant disadvantage. We wanted to add multiple hashes because of numerous new alerts coming, but we could only add them one by one, which is a considerable disadvantage in Symantec.
