Enhanced visibility and exposes vulnerabilities but needs more integration

I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

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.

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."

It takes some of the features of Defender for Endpoint EDR and provides those services for small and medium-sized business environments."

"I recommend Microsoft Defender for Business to startup organizations looking for a plug-and-play solution."

"The most effective features of Microsoft Defender for Business include its threat detection and response capabilities in managing vulnerabilities and ransomware attacks."

More Microsoft Defender for Business pros

Cons

"The integration is not as seamless compared to competitors like Palo Alto."

"With Microsoft, support is always crazy, it's not easy to get support."

"Further integration across different Microsoft products would be an improvement."

"We faced some issues while running some applications on Mac."

"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."

"The user interface has a lot of features which can make it complex and hard to adapt to for some users."

"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 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."

"The threat detection capabilities require significant customization for multistage threat detection."

"Additionally, the pricing policy poses a challenge, particularly in multi-year contracts, where other solutions like Trend Micro offer more affordable options."

"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."

Pricing and Cost Advice

Information not available

"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."

"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."
