Essential security capabilities, plenty of email protection, and enhanced data loss prevention

What is our primary use case?

This solution is a mixed product. It can be used for email security and for information protection which is basically data loss prevention. Many people do this type of setup for DLP, but it is under Microsoft's naming convention, they call it Microsoft Information Protection(MIP).

Pros and Cons

  • "Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
  • "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."

What other advice do I have?

The solution is really good, but not perfect, nothing is. They have done a very good job, they just have a little ways to go. The way their documentation is constructed, connecting the dots holistically is something people find hard and that is the reason they call people like me because I know how to connect the dots. I rate Microsoft Defender for Office 365 a nine out of ten.

Easy to set up with no configuration required, and the support is good

What is our primary use case?

We are using it with Laptops that go directly to the end-user. We used the Defender because it was already there.

Pros and Cons

  • "The good part is that you don't have to configure it, which is very convenient."
  • "We need a separate license and we don't know how to get the license that is required."

What other advice do I have?

I feel Defender is a product that is good enough, especially for small to medium-size businesses. I would rate this solution an eight out of ten.

Protects from zero-day threats and ensures that attachments and links are safe, but has a lot of false positives and should have only one plan that takes care of everything

Pros and Cons

  • "Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
  • "In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."

What other advice do I have?

I would advise others to do a proof of concept for at least a month before taking a decision. I would rate Microsoft Defender for Office 365 a eight out of ten.
