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.

Real-time file security has reduced incident tickets and improves threat detection accuracy
The best features of Symantec Protection Engine include machine learning, file reputation, and real-time scanning. It efficiently handles heavy loads through ICAP and cloud-based processing, reducing the burden on endpoints compared to Trend Micro and other endpoint security solutions. Its centralized control is also noteworthy. Through machine learning, it detects both known and unknown malware and malicious URLs, in addition to performing signature-based scans that assist SOC teams in analysis. The solution is highly effective in leveraging both machine learning and file reputation. Regarding centralized control, it offers a unified management console for policy deployment and provides real-time visibility through dashboards, helping save significant administrative time. Symantec Protection Engine has had a positive impact on our organization by enhancing our overall security posture. It effectively blocks a high volume of file-based threats across more than 200 servers, saves SOC analysts time in endpoint remediation, and streamlines compliance processes. It further strengthens security through real-time scanning and machine learning-based quarantine, blocking phishing payloads in SharePoint uploads before they reach endpoints, thereby reducing incidents by 30–40% compared to signature-only tools.

Quotes from Members

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

Pros

"Defender for Endpoint has significantly improved our security posture."
"The solution provides protections and reports about strange behavior and automatically blocks some of it. I love the way that statuses are represented."
"Defender for Endpoint is a good competitor for those looking for an EDR solution, and for those looking for a complete security suite, it's one of the better choices."
"We can react to threats faster and stop them from spreading from one machine to another. It protects from suspicious email attachment downloads. It will lock down the SOC and the workstations."
"Microsoft Defender for Endpoint's threat intelligence has helped us prepare for potential threats before they hit and take proactive steps."
"The solution has an easy-to-use interface, is always updated, and is user-friendly."
"One feature I like the most is vulnerability management, which shows any vulnerable software or OS present in my environment. Microsoft Defender for Endpoint provides a complete overview and also recommends the steps to mitigate the vulnerabilities or threats. Most of the other antivirus or EDR solutions generally don't provide vulnerability management. It is an add-on that Microsoft Defender for Endpoint provides."
"When it comes to the comprehensiveness of the threat protection from these products, so far I have seen how it's able to pick up the smallest script that is hidden in any type of malicious file."
"Symantec Protection Engine's been a game-changer for us at Kantar—blocks like 80-85% of file-based threats right at the gateway before they hit our 200 servers, cutting down endpoint incidents big time."
"What I appreciate in Symantec Protection Engine is the Virtual Policy Manager (VPM) and the Application Name feature, which are really effective."
"The operational efficiency with the high-performance scanning of Symantec Protection Engine is very good."
"Symantec Protection Engine is a cheaper and rock-solid product where basic anti-spam features and threat intelligence are needed."
"The best features that I like the most include the threat intelligence network, which is effective in protecting against evolving threats."
"Symantec Protection Engine has improved my security posture by helping me identify potentially malicious files before they reach users or critical systems, and the automated scanning process has also reduced manual efforts for my team, allowing us to focus on other security tasks and respond to threats more efficiently."
"Symantec Protection Engine provides me with the option of both cloud and on-premise solutions, which stands out for both me and my clients."
"The biggest advantage of Symantec Protection Engine is that one tool protects all, and it is centrally managed."
 

Cons

"Defender's cloud integration could be improved."
"There is complexity in accessing the dashboard."
"The solution could be even more secure and provide an even higher level of security."
"It could be easier when it comes to managing exceptions."
"My main issue with the tool is that there are too many menus."
"The onboarding and deployment could be more user-friendly, and there is room to grow in some of the reports. I don't want them to be oversimplified or overly complex, but there is room for improvement in the reporting it can do. It's relatively minor."
"The system can always be simplified and have a better integration check."
"Microsoft Defender in the basic form is not very useful for managing the security environment. The free version is not capable of covering the needs of centralized management, EDR, and behavioral analysis. If you don't have the commercial version, you can't have centralized management and set up the policies and other things. Each client is a standalone installation, which is not useful for security in an enterprise model."
"I would like to see improvements in reporting and troubleshooting capabilities for Symantec Protection Engine, as more detailed insights and simplified diagnostics would make day-to-day administration easier."
"As for pricing, I would say it is a little expensive compared to competitors, and I think the vendor could achieve more market growth if the pricing were more reasonable."
"We have scenarios in which Symantec Protection Engine misses some threats, spam, and targeted attacks that Proofpoint can catch with AI security features."
"To improve Symantec Protection Engine, I suggest simplifying its integration with other tools, as it is more complex compared to Trend Micro and CrowdStrike."
"I have concerns about scalability."
"While I have mentioned many advantages of Symantec Protection Engine, there are areas for improvement, particularly the dashboard features."
"For the improvement of Symantec Protection Engine, the engine did not work with their basic engine when I was working, which was almost three or four years before."
"Price is a significant area for improvement. The pricing is quite expensive, and it is particularly high for regular customers."
 

Pricing and Cost Advice

"This solution is part of Windows and comes included with it."
"The price of Microsoft Defender for Endpoint is reasonable. Other solutions are more expensive, such as ClowdStrike."
"Its price at the moment is very good because you get a lot of value for your money, especially with the subscriptions. If you have the E1, E3, or E5 enterprise subscription, you pay per month per user, and you get almost an infinite number of solutions. If you compare the price to the number of solutions that you get, it is a very good deal."
"It isn't cheap, but it's reasonable and fair."
"We have seen ROI. Most of the other competing alternatives will cost up to around $30 per user device. We average 400 devices. Therefore, the amount that we save each year is 400 times $30."
"It's included with the Windows Operating System, I don't pay for any licensing fees."
"It is so expensive. It isn't cheaper than McAfee or other solutions."
"Buying individual point products would've cost us a lot more money than one integrated solution that also capitalizes on Teams Voice and things of that nature. Given our size, buying individual products would have easily cost us a million dollars."
