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.

Creates robust rules for communication and data security, boosting compliance measures
I was talking with some engineer from Microsoft about how we can audit our web page. They create or add to Microsoft Purview Communication Compliance that part, the Layer seven of the OSI model, to check the application and maintain a good practice of coding. I've tried the web page part, and it works great. However, monitoring and compliance for web applications could be improved.

Quotes from Members

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

Pros

"Microsoft Defender for Business stands out due to its ease of use, particularly due to the fact that many of my customers already use Microsoft and Azure."
"If you're an Intune user, you can bring in certain capabilities like system-hardening policies, which further enhances the security."
"Everything is stable. There have been no technical errors or stability issues."
"The most effective features of Microsoft Defender for Business include its threat detection and response capabilities in managing vulnerabilities and ransomware attacks."
"I haven't had any problems with the tool's stability."
"Defender's main strength is its integration with Microsoft Sentinel, offering valuable insights."
"It is scalable."
"The interface is quite user-friendly."
"Customer support is excellent."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"The time it saves is very useful."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
 

Cons

"I have an open case for close to two months with no responses or updates, except for an email response, and I've made four or five phone calls regarding the Microsoft Interconnect for AD and cloud tenant."
"Defender's threat protection should be fine-tuned to reduce false positives. It could be more targeted, reflecting a continuous evolution in detecting. Also, it could be easier to integrate into other environments."
"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"It is not quick to make exclusions or specific configurations compared to other antiviruses on the market."
"The technical support from Microsoft is very poor. I would rate it a one, as their technical staff are very junior and take a long time to respond to simple questions."
"The user interface has a lot of features which can make it complex and hard to adapt to for some users."
"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"The security could always be improved."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"Monitoring and compliance for web applications could be improved."
"The product should incorporate more automation with the help of AI."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
 

Pricing and Cost Advice

"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's cost has been a little high, but I do not think it was terrible."
"Defender for Business is included by default with an Office 365 premium subscription."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"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."
