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.

Insightful detection and prevention of data loss mitigates legal risks and reduces potential lawsuits
Microsoft Purview Insider Risk Management was helpful in performing investigations after alerts were received. I was able to quickly identify the source of issues, which was valuable for data loss prevention. Additionally, it has saved us money on lawsuits and the loss of important confidential information that could lead to legal issues.

Quotes from Members

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

Pros

"I haven't had any problems with the tool's stability."
"The solution includes attack-savvy service and risk protection, part of data center management, and offers an effective single-dashboard view with Microsoft 365."
"Microsoft Defender for Business is good for small and medium-sized businesses. It offers solid security flexibility and integration with tools like Microsoft Lighthouse and some other software. It takes some of the features of Defender for Endpoint EDR and provides those services for small and medium-sized business environments."
"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."
"I recommend Microsoft Defender for Business to startup organizations looking for a plug-and-play solution."
"The security features are valuable because they come with more capabilities that other licenses do not have, including the enterprise license like E3."
"The most valuable feature of the solution is its central console."
"It is scalable."
"Insider Risk Management's graphing is highly specific and useful. You can see the last six months of data for the Microsoft tenant. You can easily find what you need. For example, you can filter for alerts about devices, emails, etc."
"The best thing about Purview is that it's easy to integrate with our day-to-day environment. We have Active Directory, and Word and Excel. Using a third-party vendor and trying to integrate with our existing environment would be much more challenging."
"Microsoft Purview Insider Risk Management was helpful in performing investigations after alerts were received."
 

Cons

"The areas where Microsoft Defender for Business could improve include the support, installation process, and wiki. I should be able to find solutions to issues quickly without having to delve too deep."
"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."
"The security could always be improved."
"Talking with the tool's technician about any problem is very complicated."
"Technical support could be faster to respond."
"Threat protection could be improved even though it is already a built-in feature."
"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"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 reporting capabilities sometimes leave a little to be desired. It could be improved in terms of producing reports to provide information to the C-suite or others."
"For certain things, you need to install an agent. I understand it's for integrity, but if there could be a clientless solution for certain aspects, it would make life easier."
"The user interface also isn't user-friendly. When we introduce Insider Risk Management to our clients, they often find it difficult to understand. There is too much information, and the UI is not scalable. Also, entry-level IT technicians are not always interested in learning something new. It should be clearer and easier to understand."
 

Pricing and Cost Advice

"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."
"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's cost has been a little high, but I do not think it was terrible."
