- "Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."

Chief Information Security Officer at Suri Services, SC
Excellent support, good functionality, and useful protection against online threats
Pros and Cons
- "It offers great security against malware and other threats."
- "It doesn't protect against everything. We do need protection for, for example, endpoints."
What is our primary use case?
I primarily use the solution for online protection. It protects us from malware and spam, among other threats.
I can employ my own policies, for example, attached files and email, and I can apply security to them and analyze threats that may come in. I put together the best configurations to help protect the users.
How has it helped my organization?
It has offered effective protection to help us avoid email issues. For example, my CEO in the past had been compromised with malware. When we deployed this solution, we've been able to avoid issues.
What is most valuable?
The functionality is good.
It helps maintain protection. It can protect our Microsoft operations. It offers great security against malware and other threats.
Technical support is excellent.
It is stable.
The solution can scale.
It offers good value for money.
What needs improvement?
It doesn't protect against everything. We do need protection for, for example, endpoints.
We'd like Citrix and Linux identity protection. We need security beyond just email so that we can avoid malicious threats.
For how long have I used the solution?
I've been using the solution for five years in total.
What do I think about the stability of the solution?
It is stable. I'd rate the reliability ten out of ten. There are no bugs or glitches and it doesn't crash or freeze.

Positive
How was the initial setup?
The initial setup was very easy. It was not difficult. We had good documentation in order to assist us. There's a lot of information available.

The pricing is expensive, however, it is valuable to have, so that pricing is okay.
What other advice do I have?
I'm not sure which version of the solution we're using.
Overall, I would rate the solution ten out of ten. I'm very pleased with the solution.
Which deployment model are you using for this solution?

Technical Support Manager at It Outsourced
A stable email protection tool that needs to make its implementation phase easier for smaller businesses
Pros and Cons
- "In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
- "Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
What is our primary use case?
Not a lot of our company's clients actually get Microsoft Exchange Online Protection (EOP) implemented in their IT environments.
My company's clients use Microsoft Exchange Online Protection (EOP) for email protection.
What is most valuable?
The most valuable feature of the solution is that it is a one-stop shop going through Microsoft. You don't have to worry about additional out-of-the-box features since the solution already offers a very good amount of basic protection or security for your emails. Most of our clients are small-sized businesses, so it suits them fine.
What needs improvement?
Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily. Microsoft's competitors work a lot better since their products come out of the box directly, and one needs to turn them on to make them work. Microsoft Exchange Online Protection (EOP) requires a lot of configuration, support, and management. The aforementioned areas can be considered for improvement.
For how long have I used the solution?
I have been using Microsoft Exchange Online Protection (EOP) for five years. I work at an IT support company that resells, implements, and offers support for Microsoft products.
What do I think about the stability of the solution?
My company hasn't faced any stability issues with the solution.
What do I think about the scalability of the solution?
My company hasn't had the need to use the solution's scalability, but I believe that it is a scalable product.
My company works with small to medium-sized businesses, where even among the medium-sized ones, we prefer the smaller ones.
How are customer service and support?
In general, my company is happy with Microsoft support, and we haven't needed support specifically for Microsoft Exchange Online Protection (EOP).
I rate the technical support an eight to nine out of ten.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup of the solution does not consist much of installing it, but meeting the needs of our company's clients. The setup phase requires quite a bit of planning.
There is no standard amount of time taken when it comes to the deployment of the solution. After our company's clients are prepared to make payments toward the solution, it takes around four hours to deploy the solution.
What's my experience with pricing, setup cost, and licensing?
The solution falls on the higher or more expensive side of the spectrum.
What other advice do I have?
The maintenance of the solution is neither too easy nor too difficult. The maintenance is not so easy because what tends to happen is things get set up, and those decisions don't get revisited regularly. There needs to be some process where the settings, decisions, and configurations get reviewed to determine whether they still meet the company's clients' needs regularly.
The solution can be more beneficial for medium and large-sized businesses compared to the smaller ones.
I rate the overall solution a six out of ten.

Cloud Infrastructure Engineer at Netsurit
Highly capable when it comes to protecting against phishing attacks and malware threats
Pros and Cons
- "The scalability is pretty good; it does what it is supposed to do."
- "The reporting needs a little bit of improvement."
What is our primary use case?
We use it for email protection.
What is most valuable?
Microsoft Exchange Online Protection is very good when it comes to anti-phishing and anti-malware. And the fact that it has an impersonation feature for the domain as well as users.
What needs improvement?
The reporting needs a little bit of improvement. When you compare it to Mimecast features and data porting tools, it's less superior compared to EOP.
Another area of improvement could be pricing. So Exchange Online Protection has a higher price compared to its competitors.
For how long have I used the solution?
I've been working with it for over three years now.
What do I think about the stability of the solution?
I would rate the stability a nine out of ten.
What do I think about the scalability of the solution?
I would rate the scalability an eight out of ten. The scalability is pretty good; it does what it is supposed to do. I haven't encountered many issues because Microsoft regularly updates its product.
We're just over 650 users in our company using this solution.
How are customer service and support?
The customer service and support have been really helpful. Whenever we raise a support ticket with them, they respond in a timely manner, and almost 99.9% of the time, issues are resolved.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have used MessageLabs in the past, and I would say that EOP is better than MessageLabs in terms of the interface and ease of use.
How was the initial setup?
The initial setup is easy. Moreover, it is easy to maintain. The deployment model is cloud-based, but we are in a hybrid environment. So it does protect our on-premises environment as well.
What about the implementation team?
The initial deployment was done by our IT team. In our IT department, I would say roughly 12 people are required for maintenance.
What's my experience with pricing, setup cost, and licensing?
It's a high price. When comparing it to Microsoft Defender and Mimecast, it is more expensive.
What other advice do I have?
I would definitely require using this solution. Overall, I would rate the solution a nine out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure
