Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Ease of deployment and cost-effectiveness boost operational efficiency
I have recommendations for increasing dashboard customization. Currently, we are using custom dashboards, but they are not effectively customizable. If they provide better customization options, it would be easier to understand everything in a single dashboard instead of navigating through dropdown menus to see reports. Additionally, log retention is currently 30 days, but some customers request to extend it to 60 days. Having 60 days of log retention would be helpful for maintaining logs.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup is just a standard process."
"We can migrate seamlessly without any disruptions to our operations."
"The pre-set policies and configuration analyzer are the most valuable features."
"The scalability is pretty good; it does what it is supposed to do."
"It's all running in the backend, so it doesn't affect the app functionality."
"It's definitely scalable."
"The email policy configuration options in Microsoft EOP are satisfactory."
"You can use the product to create special accounts."
"Compared to other email solutions such as Cisco, price-wise, we get this solution within 50 to 60% of the average."
 

Cons

"The solution needs to improve its backup."
"It would be helpful for customers if Plan 1 features were included with EOP."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"The security features could be better."
"The solution must improve the user experience."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"I think the implementation could be more streamlined."
"Threat intelligence is adequate because they are using Microsoft GTI threat intelligence, but we need to increase protection against phishing and spam mails."
 

Pricing and Cost Advice

"The solution should reduce the cost."
"The product is expensive."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"It is a low-price solution."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution falls on the higher or more expensive side of the spectrum."
