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.

Facilitates compliance and records management but needs user-friendly enhancements
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. The importance of Microsoft Purview Communication Compliance building taking into account critical regulations from around the world is very significant. It helps us stay up to date. While I don't need the functionality, Purview delivers data protection across multi-cloud and security platform environments, including AWS and GCP. It takes into account critical regulations from around the world. It helps us stay up to date with what's going on. We can show compliance in real-time. It's very easy to pull records. The time it saves is very useful.

Cons

"We faced some issues while running some applications on Mac."
"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."
"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."
"Additionally, the pricing policy poses a challenge, particularly in multi-year contracts, where other solutions like Trend Micro offer more affordable options."
"The threat detection capabilities require significant customization for multistage threat detection."
"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."
"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."
"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."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"The product should incorporate more automation with the help of AI."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Since we're a nonprofit, we get pretty good discounts on the tool."
