Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.
William Tuleja - PeerSpot reviewer
Integration with existing tools boosts management efficiency
The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong. Often, it just links back to a generic KB article without additional information. When it happens, it requires extra detective work. This issue doesn't occur often but can be annoying.

Cons

"I am not satisfied with Microsoft's technical support. There are challenges with the knowledge and experience of the support staff, frequent redirection between departments, and slow response times."

"The pricing of Microsoft Defender for Business has a long way to go since people are still preferring solutions such as CrowdStrike and Palo Alto."
"If I need logs and don't have local storage bundled with Defender, I need to add workspace and log analytics, which is costly for storing logs of 2 GB, 5 GB, 10 GB."
"We face a licensing issue with Windows 11 Enterprise not reflecting in our portal, which affects activation. Microsoft's support did not resolve this issue, even after sharing remote desktop and screen details."
"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."

Pricing and Cost Advice

"Defender for Business is included by default with an Office 365 premium subscription."
"It has to get more competitive because we are starting to see some of the competitors providing better pricing, and some of it, of course, is to gain market share. The Defender product pricing is probably a little higher than the competitors."
"The tool is cheap, while some other solutions are more expensive. I remember the tool cost about five euros for a workstation or for a user on a monthly basis."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"The tool's cost has been a little high, but I do not think it was terrible."
