Sublime Email Security Platform Reviews & Product Details

Easy to deploy, with excellent out-of-the-box coverage. It requires minimal configuration, and the Sublime team handles most of that after the deployment. Review collected by and hosted on G2.com.

It currently lacks outbound features. I understand these are on the roadmap, but they’re still missing as of now. Review collected by and hosted on G2.com.

API-based deployment that quickly catches phishing and BEC with low false positives, clear reporting, and simple policy tuning. Review collected by and hosted on G2.com.

Limited advanced reporting and audit exports, uneven integration depth, and an admin UI that lacks fast search/bulk actions; pricing also ramps up quickly as mailboxes grow. Review collected by and hosted on G2.com.

What’s great about Sublime is how flexible it is. If you’re into that sort of thing, you can geek out on detection rules, figure out why something was quarantined, go on threat hunts, and even create your own detection rules. You can also set up automation to make your security ops simple; or if you’d rather, you can just deploy it and forget about it – it’s completely up to you. Deployment literally takes 5 minutes and the customer support team is pretty much an extension of your existing team - no ask is too small. Review collected by and hosted on G2.com.

There’s not much to dislike, but if I had to pick something, it would be the learning curve for some of the more advanced features. However, once you get the hang of it, the platform becomes a powerful tool, and the flexibility it offers is well worth the initial effort. Review collected by and hosted on G2.com.

Sublime is a reliable, trustworthy platform that consistently delivers proactive rule logic and timely, dedicated customer support. It's user-friendly platform and minimal learning curve has been critical in enhancing my D&R team's operations. The Sublime team also goes above and beyond in their reception to feedback, quickly iterating on feature requests and enhancements to the platform. It's clear we share aligned goals, making this one of the most valuable partnerships my team has. Review collected by and hosted on G2.com.

No complaints here! I've interacted with the platform frequently over the years, and two things have remained consistent: its reliability and ease of use, and how everyone on the team is exceptionally technical, responsive, kind, and committed. They consistently go above and beyond to facilitate a strong, collaborative working relationship and ensure a seamless detection-to-response pipeline. Review collected by and hosted on G2.com.

The ease of the deployment and rapid response to evolving email security threats. We were able to enable it for a large organization and have it work immediately, allowing us to start remediating threats in our email environment. Sublime is constantly pushing out detection rules for the newest threats and picking up on things way before any other tool could. Review collected by and hosted on G2.com.

I have yet to find something I dislike about the product. Review collected by and hosted on G2.com.

We recently swapped our SEG from a competitor to Sublime and the experience so far has been excellent. Sublime’s team and our CSP have been readily available to bring our team up to speed and aid in making the transition seamless. Having full transparency over our detection rules has elevated our teams ability to detect and respond to email threats. Review collected by and hosted on G2.com.

There is a significant learning curve required to fully utilize Sublimes capabilities, specifically regarding MQL. However, Sublime overs public and private training sessions to increase our ramp up rate. Review collected by and hosted on G2.com.

I love how easily it is it implement, its effectiveness, and how transparent the whole software is about what it detect & why. You will very quickly see a return on investment due to much cleaner inboxes, rid of malware, phishing attempts and other attacks. They continually add new features and detections. I feel sublime is the best email security platform out there right now, and one of the strongest tools at our disposal. Review collected by and hosted on G2.com.
