Sentiment score
7.1
Sublime Security efficiently scales with growing email volumes and evolving threats, supporting enterprise expansion while maintaining performance.
Despite nearly doubling the number of mailboxes and adding significantly more detection rules, the service remains just as fast as it was when we first implemented it.

Its scalability is also good, as it can scale with the number of protected mailboxes or users, or as email volume grows, supporting enterprise development across Microsoft 365 or Google Workspace.

Stability Issues

Sentiment score
8.5

Sentiment score
8.6
Sublime Security is highly praised for stability, reliability, zero-crash performance, efficient threat handling, and scalable infrastructure.
Sublime Security acted quickly; once Microsoft alerted Outlook about the incoming email, Sublime Security managed to pull it from the stream before it had a chance to appear in the user's inbox.

Room For Improvement

Users feel Avanan needs improvements in Active Directory dependency, email quarantining, AI logic, training, UI, performance, pricing, mobile app, and integrations.
Sublime Security requires enhanced reporting, better integration, improved automation, and accessible pricing to appeal to mid-sized businesses.
One breach could potentially put a small company out of business, so having a tool such as this might save them from that fate.

Sublime Security could be improved by enabling more integration, better customization of alerts, and more detailed reporting.
Soc Analyst at a manufacturing company with 10,001+ employees
Regarding needed improvements, I think the documentation is generally useful, but I would appreciate more beginner-friendly guidance and practical SOC examples, particularly around setting up detections, tuning rules, and integrating Sublime Security with SIEM and SOAR platforms.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

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.
