Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

"I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."

Cons

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Configuration at the mid-level could be improved for the support team."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"To improve Microsoft Defender for Office 365, it would be nice to have more accessibility for users to see on their end what they are doing that could cause a threat."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"Several simulation options are available within 365, and the phishing simulation could be better."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"The technical support needs improvement."
 

Pricing and Cost Advice

"The pricing has become expensive."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The license is expensive because the cost is based on the number of users."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"It's a user-base subscription."
"The pricing is normal. Considering its popularity, it's not overpriced."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The solution is overly priced."
