Find out what your peers are saying about Microsoft, Cisco, TitanHQ and others in Email Security."Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The product is not resource-intensive."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The solution could be less expensive."
"The installation is not so straightforward."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The solution is complex and not easy to use."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"While it's quick and easy, the initial setup could be more user-friendly."
"I'd like to have better support from the product in the future."
"They should improve the cookies management feature."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
