We use it for email protection.
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?
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

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.
What do I think about the scalability of the solution?
I'd rate the solution eight out of ten in terms of scalability. It can scale.
How are customer service and support?
Microsoft support is excellent. They are very helpful and responsive.
How would you rate customer service and support?
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.
What's my experience with pricing, setup cost, and licensing?
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?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Sr. Network Administrator at ACMC
An easy solution with a straightforward setup
Pros and Cons
- "It is an easy solution."
- "The security features could be better."
What is our primary use case?
It is an easy solution. It is useful for local users and our company because we use Microsoft 365. It is also free with Microsoft 365.
What needs improvement?
The security features could be better and more secure in the next release.
For how long have I used the solution?
We have been using this solution for two years.
What do I think about the stability of the solution?
It is stable.

How are customer service and support?
We've used technical support a few times, and they've helped us.
How was the initial setup?
The initial setup was straightforward. It has already established standards that are configured.

Technical Operations Manager at BTSERVISI
Is scalable, stable, and fairly easy to install
Pros and Cons
- "It's definitely scalable."
- "Microsoft has some training portals, but more could be developed."
What is most valuable?
It's definitely scalable.
What needs improvement?
The price could be lower.
Microsoft has some training portals, but more could be developed.
Additional documentation could be added.
What do I think about the stability of the solution?
It's stable if you take care of it, but it's not an install-it-and-forget-about-it kind of product. You have to maintain it.
What do I think about the scalability of the solution?
It's definitely scalable.
How are customer service and support?
The quality of the technical support is good, but the speed could be better. I would rate it at three on a scale from one to five.
How would you rate customer service and support?
Negative
How was the initial setup?
It's neither very easy nor very complex to deploy Microsoft Exchange Online Protection. It's in-between. On a scale from one to five, I would rate deployment at three.
What's my experience with pricing, setup cost, and licensing?
The price could be lower.
What other advice do I have?
On a scale from one to ten, I would rate this solution at eight.

Solutions Architect at One Click
Protects our customers from spammers
Pros and Cons
- "It has a really nice web-based administration console."
- "I think the implementation could be more streamlined."
What is our primary use case?
It's a spam filter and an antivirus solution. It protects our clients from spammers.
What is most valuable?
It has a really nice web-based administration console. Thanks to this, our clients are not tied to a particular server or workstation. They can just hit a URL anywhere in the enterprise and view the console.
The included patch management system is really good. It keeps itself up to date which is critical when you're dealing with anti-virus and spam filtering. Overall, I think it's really a great product.
What needs improvement?
It kind of has a heavy footprint — in terms of an implementation footprint. I think the implementation could be more streamlined. The implementation could be more flexible in terms of allowing users to pick and choose where they want to deploy.
Personally, I like to be able to pick and choose what I'm implementing and where I am implementing it in the environment instead of having to install the whole stack.
In the next release, I would like to see them add some features beyond just spam and anti-virus. Maybe some bulk email tools — in terms of being able to send them from within the environment. Send group emails, send information to the administration team; I'd like to see them add some MailChimp kind of functionality or mailing lists.
Instead of just providing spam and anti-virus filtering, I'd like to see them add more feature functionality. The one thing that I don't like is that it's very much a point product. It just does what it does, very specialized. I think this industry as a whole is going away from point products and heading towards suites — integrated suites that do a number of different things. I think that they would be wise to fold this into a broader overall suite of products.
For how long have I used the solution?
I have been using Microsoft Exchange Online Protection for roughly 15-16 years.
What do I think about the stability of the solution?
This solution is exceptionally stable. It scales excellently for what it's used for.
How are customer service and technical support?
The technical support is outstanding.
How was the initial setup?
The initial setup is straightforward.
What was our ROI?
ROI-wise, this solution has been great.
What other advice do I have?
If you're interested in using this solution, make sure you understand the technical requirements and deploy it somewhere where it will have access both inside and outside that it needs. Inside, it needs to see the mail stores, and outside it needs to be able to download the packages that it needs to provide the spam and anti-virus filtering with protection.
Overall, on a scale from one to ten, I would give this solution a rating of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Server Technician at Matupunuka ICT
A stable and scalable filtering solution
Pros and Cons
- "We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
- "When the product is being updated, it changes some of the setups. The support team is also not good."
What is our primary use case?
We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features.
What is most valuable?
What needs improvement?
When the product is being updated, it changes some of the setups. The support team is also not good.
For how long have I used the solution?
I have been using Microsoft Exchange Online Protection since 2019.
What do I think about the stability of the solution?
It is a stable solution.
What do I think about the scalability of the solution?
It is a scalable solution. I've recommended the solution for small, medium, and large enterprises.
How was the initial setup?
The initial setup is straightforward. But if you do not know what you are doing then it can be troublesome. There are a lot of terms that they use for their online product. But we need to familiarize ourselves with the old jargon.
The customers try to deploy it on their own and when they fail they involve us. The deployment takes a day because you still have to document everything you did. You still have to show the local admin what to do, and how to manage it. I can do the deployment myself, but I do it together with the local guys so that we can all be on the same load.
What's my experience with pricing, setup cost, and licensing?
The pricing of the solution is reasonable. We are usually local, and most of our clients are in the development phase. So they're taking the governmental discount. We do not pay for extra support.
What other advice do I have?
I advise people to use it. I rate the overall solution a nine out of ten.

Cloud Analyst at Cloud2Go
Is stable, scalable, and easy to administer
Pros and Cons
- "The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
