Reporting could be one of the areas for improvement, as they could put more reporting into Microsoft Exchange Online Protection (EOP) natively rather than requiring additional licensing or connecting to other parts of the Microsoft suite, but it depends on the license you have. There aren't significant concerns with Microsoft Exchange Online Protection (EOP), as it depends on what customers expect; if they expect more features, then it depends on what Microsoft 365 license they have. The important thing is to ensure they are using all the security features they get with their licensing. The basic one is Microsoft Exchange Online Protection (EOP). While it's nice to have more functionality, that's available through other licensing programs with Microsoft. While we'd prefer more features, as a basic tool, it's fine, but more advanced features come with the add-ons from other parts of the Microsoft 365 licensing. One feature that could improve Microsoft Exchange Online Protection (EOP) is automated malware detection, where it actually analyzes the file offline in a sandbox to determine if it's safe, potentially reducing false positives.

I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

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

Pros

"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"It provides security to both on-premises and Azure infrastructures."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"The initial setup was easy. The configuration process is very straightforward."
"Online Protection's most valuable feature is its admin interface."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"The product's most valuable feature is third-party integrations."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
"I like its ability to detect and block."
 

Cons

"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"Microsoft has some training portals, but more could be developed."
"The solution lacks to elaborate on its spam policies."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"The reporting needs a little bit of improvement."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
 

Pricing and Cost Advice

"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The price of Microsoft Exchange Online Protection is reasonable."
"The price could be lower."
"The solution is priced high and could be less expensive compared to other solutions."
"The solution should reduce the cost."
"Online Protection is fairly expensive."
"The product's pricing is competitive for the US market."
"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."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
