Automatically isolates threats and integrates with logging to reduce response time
Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

Provides end-to-end antivirus protection and has good stability
Symantec Endpoint Protection provides end-to-end protection. Along with antivirus protection, it has a lot of key areas, including intrusive prevention, firewall features, and application and device control. It can integrate with other Broadcom solutions, such as Symantec Messaging Gateway and Symantec DLP. If you want to send an email, it gets scanned through endpoint protection and DLP. We get all Symantec functionality in a single pane.

Quotes from Members

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

Pros

"Overall, this is a good product and I have never been disappointed with it."
"Since we started using this product, we have not had any breaches."
"It performs well. The stability is seamless."
"I find the entire Microsoft Defender for Endpoint valuable because it finds not just definition-based threats but also behaviors."
"It can reach our applications and PC activities in the cloud."
"I am using it for very simple purposes. It is perfect and quite effective. I have been using it for a while, and I have never had any virus infection, data leak, or other security breaches. It works fine for standalone purposes. If you log on to OneDrive, it has ransomware protection."
"Defender is stable enough and is competitive with the other products in the market."
"It is very simple to use and easy to scan systems."
"The most valuable feature is NetFlow threat protection."
"Symantec Endpoint Protection provides end-to-end protection. Along with antivirus protection, it has a lot of key areas, including intrusive prevention, firewall features, and application and device control."
"The great advantage in using this product is it creates multiple services."
"The technical support services are excellent."
"They have a very simple and easy implementation; they have been around for a long time, and they have been very easy to deploy, support, and manage."
"Endpoint to network is a good feature, it can protect the line."
"You don't have to buy a separate email security platform. You can enable that using their endpoint, and I like that. You don't have to have two agents running on the same box."
"The product integrates well with our systems, and we have not encountered any problems."
 

Cons

"The major area for improvement is the integration with a managed service provider."
"The solution has minimal customization options, especially compared to Mandiant, so we want to see more scope for customization. A single portal for customization would also be a welcome addition."
"Microsoft Defender for Endpoint is secure but when it comes to security all solutions could improve security."
"Some integration components for Mac should be added. We use both Windows 10 desktops and Mac desktops, but presently, the Mac component is still lagging a bit behind."
"The solution could improve by providing more integration."
"Sometimes it is a little lacking, but for the most part, they are able to provide exactly what I need."
"The frequency of the patching, and the frequency of the updates, are not included with the free version."
"We would like to see more tools for managing on-premises security... Sometimes, we have the tools, like Defender, to manage security in the cloud, but because we are so focused on the cloud, we forget the fact that we need to be sure about the security of the on-premises environment, specifically Active Directory."
"The support has dropped down to a five out of ten."
"The support for new OSs and older OSs could be a little tighter. They need to be more upfront about what protection services they're going to provide on new OSs. I haven't seen the Windows 11 version out yet. It is either already released in Beta, or the Beta will be released soon. There could be a little bit more advanced updates on what they're doing to help protect Windows 11 environments. They can let us know in advance so that we know it is going to be protected. We can't roll out the new OS without putting end-point protection on it. So, they should tell us what is their support model for that, and what are they doing to protect Windows 11. They're not telling me, and that's a criticism. The same issue is applicable to all the other antivirus tools. It is not just Symantec; all of them have this problem."
"The product's support services need improvement."
"They could enhance the solution to work across all devices, including Android, iOS, and Mac, and make it more user-friendly."
"There are limits with respect to blocking files by hash value or blocking IP addresses, and these limits should be removed."
"Not ideal for advanced threat protection."
"Solutions like CrowdStrike, ESET, and SentinelOne have really jumped ahead on behavioral and algorithm-based detection capabilities. Symantec is trying to catch up, but they still have some limitations of being an old-school AV protection program and adding AI and behavioral learning and detection algorithm."
"The administration interface needs a lot of improvement. It should be UI based, and simple. They need to improve it. It's pretty much not that friendly compared to what we were using as Bitdefender before. It's okay but is improving, actually."
 

Pricing and Cost Advice

"We mostly use Microsoft products. We use Office 365, and we use Azure. We're also a Microsoft partner. So, the licensing was much cheaper for us, and at the same time, a lot of the features that we were looking for were included in Defender."
"This solution is part of Windows and comes included with it."
"It came with Windows."
"The solution is included with Microsoft Windows."
"The solution is free."
"Microsoft Defender is an expensive product in my country."
"The product is free of charge and comes integrated into Windows."
"The license cost is around $35 per machine, which is not expensive compared to other products."
"Symantec Advanced Threat Protection's pricing is comparable."
"The price is quite expensive."
"Pricing is good. It is nice to have a great product at a fair price."
"The pricing of this solution is inexpensive and affordable."
"Symantec Endpoint Protection has an average price."
