Email security effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.

Improves decision-making with clear verdict explanations and works well across multiple environments
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

"Data loss and data leakage prevention are well deployed which helps businesses to scale and expand effortlessly without any trouble."
"The first most remarkable thing is the integration with the Office 365 solution, which is easy, fast, and totally transparent for the user."
"It is fast and quite effective in terms of preventing any security incidents."
"The incorporated AI capabilities are particularly notable, functioning as AI versus AI, and it has protected us from various threats with a nice dashboard that shows if anything is missed by MS 365."
"The advanced phishing protection is proactive in catching threats before users even see them; it does not just block obvious spam, it can spot subtle impersonation attempts and suspicious links that appear legitimate at first glance."
"The dashboard provides information to investigate more about malicious activity and blocked emails."
"It helped us to bring security compliance and ensure system robustness throughout."
"The option to set a copy is beneficial."
"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."
"So far, I do not see any problem with Sublime Security's support or their customer service."
 

Cons

"They could continue to offer more stringent security policy measures for threat point management."
"The only area for improvement is the language of the support. The support is only available in English."
"The sanitization on the file needs improvement."
"It's not fully integrated with Google Workspace, and the statistics don't update in real-time."
"They should consider a module that allows the customizing of reports so we can generate executive information for the client (to explain in simple language the general security situation in the SaaS environment)."
"There is always room for improvement and growth."
"From time to time, the system's administrators notice the increase in the false-positive alerts being reported by CloudGuard SaaS."
"They could help us be integrating features with solutions from third parties."
"With Sublime Security, so far, I have seen a lot of false positives, and it is something that can bring a lot of administrative overhead."
"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."

"I rate the platform’s pricing a seven and a half."
"The product’s price is very high."

"The product is expensive."
