## About Sublime Email Security Platform
Sublime’s agentic platform stops more email attacks with less work. Our AI agents work like a digital SOC team in your environment, triaging and blocking advanced threats while adapting protections at adversary speed. It provides full transparency and automation by default, with control on demand for advanced teams, eliminating vendor bottlenecks or one-size-fits-all limits. Core Outcomes (The What): - Stop More Attacks with Fewer False Positives - block sophisticated threats (BEC, novel phishing, QR-based phishing) and reduce the false positives that waste time and disrupt workflows. Our tailored protections deliver a demonstrably higher catch rate, validated by the world&#39;s most demanding security teams. - Automate the Abuse Mailbox - Our Autonomous Security Analyst (ASA) automates triage, investigation, and remediation of user-reported email, cutting MTTR from hours to seconds and freeing your SOC team to focus on the threats that matter most. - Adapt Defenses Automatically. - When a missed attack is identified, we can create new coverage in hours. Our Autonomous Detection Engineer (ADÉ) generates, backtests, and deploys org-specific coverage, eliminating vendor ticket limbo. Differentiators (The How): - A Team of Agents using AI, Not Just a Black Box - Sublime deploys a team of specialized agents - like an analyst and a detection engineer - that use AI to protect, triage, and adapt your defenses. Unlike an opaque, monolithic AI, our agentic approach provides full transparency into every action, with visible decision history, message lineage, and backtests. - Org-Specific Protection, Not One-Size-Fits-All - Our Distributed Detection Model (DDM) is the foundation of our platform. It runs per-environment coverage that adapts to the unique attacks you face, allowing us to safely deploy protections that would be noisy in global models - something centralized systems simply can’t support. This means higher day-one efficacy and fewer false positives. - Autonomous by Default, Control on Demand - By stopping more attacks and reducing false positives, Sublime delivers a superior autonomous experience that requires less work. For advanced teams, the platform is fully extensible, allowing you to author your own detections and hunt for threats with a level of precision that one-size-fits-all solutions can&#39;t. Innovative organizations including Spotify, Snowflake, Brex, Elastic, Compass, Anduril, SentinelOne, and others rely on Sublime to secure the business and keep teams focused on strategic defense. 🔗 Learn how Sublime helps security teams stop more attacks with less work at sublime.security

## Sublime Email Security Platform Reviews
  ### 1. Accurate Out of the Box, Transparent Detections, and Powerful Automations

**Rating:** 5.0/5.0 stars

**Reviewed by:** John H. | Senior Email Engineer, Enterprise (> 1000 emp.)

**Reviewed Date:** February 11, 2026

**What do you like best about Sublime Email Security Platform?**

I like that Sublime has a high degree of accuracy out of the box negating a long tuning process. The regular updates to existing and creation of new core detections keeps us well protected. The ability to create custom detection, create bespoke automations is a massive plus point. I like that the detection logic is transparent, so you always know why something was flagged. The API features also make it simple to integrate into existing workflows and remove repetitive manual tasks.

**What do you dislike about Sublime Email Security Platform?**

Sublime develops and releases new valuable features regularly that we would love to use. Unfortunately, inconsistencies in regional hosting outside of the direct control of Sublime can mean that sometimes these valuable new features don’t appear in our region right away.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime greatly strengthens our overall detection stack by adding defence in depth, its automated remediation of threats and it's automated analysis and remediation of user‑reported phishing significantly reduces manual investigation time whilst maintaining or improving response quality.

  ### 2. Flexible Detection Rules with Sublime Email Security

**Rating:** 5.0/5.0 stars

**Reviewed by:** Jack G.

**Reviewed Date:** February 17, 2026

**What do you like best about Sublime Email Security Platform?**

I appreciate how user-friendly both the UI and API of the Sublime Email Security Platform are, which allows me to create in-depth detections and automations easily. I like that Sublime MQL facilitates deep customization when creating detection rules, capturing specific scenarios with various email attributes. The platform provides complex detection rule creation that would be challenging with other solutions, and it's impressive how the functions in MQL allow for intricate rule construction, down to prevalence within the configured tenant. The powerful language of Sublime provides extensive coverage with its rules, which is another aspect I find valuable.

**What do you dislike about Sublime Email Security Platform?**

Availability of ASA via the Sentinel integration? Allowing the summary to be forwarded to Sentinel.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

I use Sublime Email Security Platform for creating complex detection rules efficiently with MQL. The user-friendly UI and API enable seamless detection and automation, and the platform's powerful customization allows specific email scenarios to be captured.

  ### 3. Transparent Email Threat Detections That Build Trust and Speed Response

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Graphic Design | Mid-Market (51-1000 emp.)

**Reviewed Date:** February 05, 2026

**What do you like best about Sublime Email Security Platform?**

One of the strongest aspects of Sublime is how transparent its detections are. Instead of operating as a black-box filter, Sublime clearly shows why an email was flagged, including the specific signals, patterns, or behaviors that triggered the alert. This makes it much easier for IT and security teams to quickly validate threats, reduce false positives, and build trust in the system’s decision-making. That level of visibility also improves incident response and supports better long-term tuning, since administrators can understand exactly what the platform is catching and why.

**What do you dislike about Sublime Email Security Platform?**

Sublime is primarily focused on detection and response rather than bundling broader end-user awareness or auxiliary security features, so organizations looking for an all-in-one suite may need to pair it with separate tools. In our case, moving from Avanan to Sublime also meant giving up some nice-to-have features such as geographic threat maps, Shadow IT visibility, and certain built-in reporting elements that were more readily available in the Avanan platform.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime has been particularly effective in reducing the volume of business email compromise (BEC) and impersonation attacks that previously slipped through our legacy email filtering tools.

  ### 4. Advanced Threat Protection with Stellar Support

**Rating:** 5.0/5.0 stars

**Reviewed by:** Rob C. | IT Cloud Security Engineer

**Reviewed Date:** February 09, 2026

**What do you like best about Sublime Email Security Platform?**

I really like that the Sublime Email Security Platform is simple to use and very customizable, which is important for our large and sometimes complex organization. We love that the engineers are also the support team and are always happy to help, whether by jumping on a call or messaging in Teams. It's easy and straightforward to manage, thanks to this hands-off approach where it basically does everything itself.

**What do you dislike about Sublime Email Security Platform?**

The only thing I can think of is there's a feature that only processes data in the US (ADE and the ability to automatically share emails with Sublime), whereas we need everything to be processed in the UK. It's just very key for us that everything's in the UK.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

I use Sublime Email Security Platform as a post email proxy against advanced phishing threats. It's able to identify AI-generated threats that traditional gateways and detection services can't detect.

  ### 5. Enterprise-Level Security, Effortless Onboarding

**Rating:** 5.0/5.0 stars

**Reviewed by:** Andrew M.

**Reviewed Date:** December 29, 2025

**What do you like best about Sublime Email Security Platform?**

I like that the Sublime Email Security Platform feels like an enterprise product and it was really easy to onboard our Google Workspaces account, all for free. I appreciate how it helps filter out malicious and spam content, while also allowing us to whitelist customer email domains and craft specific rules. The comprehensive rules make decision-making straightforward. Additionally, reviewing actions taken by the system has become an important internal security process to ensure we reduce false positives. The platform's interactive wizard automated our setup process, making it very easy to get started, and it feels very complete for the price point, especially since we're under the threshold for free use.

**What do you dislike about Sublime Email Security Platform?**

It takes a little bit of trial and error to learn how to apply actions to the 700+ built-in rules, I would of appreciated some additional help/guidance on setting up rule actions from within the console.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

I use Sublime Email Security Platform for inbound email security, anti-phishing, anti-spam, filtering malicious content, whitelisting domains, and creating specific rules. It enhances security review processes, offers comprehensive rules, easy onboarding, and is free for small teams.

  ### 6. Best-in-Class Email Protection with Exceptional Usability

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.)

**Reviewed Date:** February 06, 2026

**What do you like best about Sublime Email Security Platform?**

What stands out most about Sublime is how effectively it combines best-in-class email protection with exceptional usability. The platform does a great job of blocking phishing, malware, and other advanced threats without impacting user experience — false positives are minimal, and legitimate communications flow without friction.

**What do you dislike about Sublime Email Security Platform?**

Overall the experience has been positive

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime Email Security Platform is solving several key challenges in our email security stack — especially around advanced threat detection, phishing resistance, and policy enforcement. Before Sublime, it was harder to tailor protections to specific user groups and unique risk scenarios in our organization. The platform’s customizable rules engine has been a game-changer — it allows us to define precise policies that align with our business needs and security posture, such as rules based on sender behavior, attachment characteristics, internal user risk profiles, or domain spoofing patterns.

This flexibility means that we can block or quarantine high-risk email types proactively, while reducing false positives for trusted communications. As a result, we’ve seen fewer successful phishing attempts, faster incident response, and less noise for our security team, which in turn improves operational efficiency. The ability to fine-tune rules without waiting for vendor intervention has also helped us stay agile as threats evolve.

Overall, Sublime helps us protect our users more effectively, cut down on security overhead, and enforce consistent policies that match our risk tolerance — all while maintaining email usability for the business.

  ### 7. Best-in-Class Security Platform

**Rating:** 5.0/5.0 stars

**Reviewed by:** Patrick L. | Information Security Manager, Mid-Market (51-1000 emp.)

**Reviewed Date:** August 29, 2025

**What do you like best about Sublime Email Security Platform?**

The platform is incredibly intuitive, giving us full visibility into email threats without complex setup or management. The dashboards and alerting make it easy to stay ahead of attacks. The ability to customize detection rules and workflows is a huge plus. We’re not locked into a one-size-fits-all product—it adapts to our environment.

We were able to connect Google Workspace and start seeing results in less than 10 minutes.

**What do you dislike about Sublime Email Security Platform?**

Sublime's Message Query Language (MQL) is powerful and incredibly useful for creating detection rules and automations, but it does require some trial and error and time spent with documentation to be able to use it to its full potential.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

We are solving a number of issues with Sublime:
- The Google Workspace-native email security tools are cumbersome to use and don't provide much visibility into why something was flagged. Sublime provides a lot of detail on attack signals and message details, allowing our Security team to analyze potential threats faster.
- Sublime's detection of malicious emails is very good. During our first week, a number of employees received a well crafted phishing email that Google did not detect, but Sublime flagged it as malicious instantly.
- Sublime allows us to automate the response to malicious emails, which reduces the risk to end users and saves Security teams valuable time.

Allows for hands-off handling of email security with high confidence. Great integrations with newer-gen security awareness training products, and great integration with Microsoft and Google built-in reporting tools

  ### 12. Reliable detection out of the box, unrivalled support, transparency and endless customisation.

**Rating:** 5.0/5.0 stars

**Reviewed by:** John H. | Enterprise Platforms &amp; Services - Senior Email Engineer, Enterprise (> 1000 emp.)

**Reviewed Date:** June 06, 2025

**What do you like best about Sublime Email Security Platform?**

I'm a big fan of the transparency of the platform and how you can see the what, the why, the how a threat was detected and prevented.

The limitless ability to tune and customize detections to provide the best coverage for our organisation (whilst still providing reliable coverage right out of the box). Initial deployment is a piece of cake.... In just a few clicks you are ingesting historic data and detecting threats.

Another stand-out to me is the excellent slack community where you can not only engage directly with the Sublime team for support but where other customers can share ideas, detections and threats they have seen.

**What do you dislike about Sublime Email Security Platform?**

I find it hard to offer criticism of Sublime as any "dislikes" I had have been addressed by Sublime since we became a customer.

If I had to be pressed I would like to see some improvement in the native reporting abilities of the platform and the capability to export these reports for consumption.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime has been a game-changer in tackling advanced email threats. It gives me real peace of mind knowing our environment is well protected.
The level of security it provides allows us to focus on other tasks without constantly worrying about email threats.

**Reviewed Date:** February 09, 2026

**What do you like best about Sublime Email Security Platform?**

- Easy setup
- Helpful customer success & customer support team
- Good amount of flexibility and customisation options due to the inherent transparency of the platform

**What do you dislike about Sublime Email Security Platform?**

- Some rough edges (e.g. audit logs are not quite there yet ; sometimes the UI doesn't link to the appropriate place ; encoding issues ; replies to user reports)
- Slightly more false positive than competitors
- Delay on planned features

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Reducing the amount of phishing email that we receive as an organization to decrease the risk of a successful phishing attempt.

  ### 15. As my colleague one said: "It's built for analysts by analysts"

**Rating:** 5.0/5.0 stars

**Reviewed by:** Christopher C. | Principal Information Security Engineer, Enterprise (> 1000 emp.)

**Reviewed Date:** May 21, 2025

**What do you like best about Sublime Email Security Platform?**

It’s one of the few tools we’ve implemented that truly just works. Low maintenance, no tuning—it just does what it’s supposed to do.

**What do you dislike about Sublime Email Security Platform?**

Sublime just works and I can't think of any downsides of someone using Sublime. Product is awesome, the Sublime folks are amazing and could not say anything bad about it.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

We needed a solution that could reliably detect threats and automate remediation to free up analyst time for more strategic security initiatives. Before Sublime, analysts were spending hundreds of hours handling phishing cases, with each investigation taking 10-15 minutes and often requiring follow-on actions from Elastic’s Incident Response team.

After deploying Sublime, the number of investigations dropped by 62% within the first quarter, but the percentage is likely higher due to benign reports unrelated to phishing.

  ### 16. Easy Deployment with Excellent Out-of-the-Box Coverage

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Legal Services | Enterprise (> 1000 emp.)

**Reviewed Date:** February 06, 2026

**What do you like best about Sublime Email Security Platform?**

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.

**What do you dislike about Sublime Email Security Platform?**

It currently lacks outbound features. I understand these are on the roadmap, but they’re still missing as of now.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

It captures malicious emails that were missed by the email gateway. It’s also one of the very few products that offers complete UK datacentres for processing email data.

  ### 17. Fast, Accurate Phishing Protection with Effortless Deployment

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Airlines/Aviation | Enterprise (> 1000 emp.)

**Reviewed Date:** November 18, 2025

**What do you like best about Sublime Email Security Platform?**

API-based deployment that quickly catches phishing and BEC with low false positives, clear reporting, and simple policy tuning.

**What do you dislike about Sublime Email Security Platform?**

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.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

It tackles the biggest email-borne risks—phishing, BEC/impersonation, vendor fraud, and malware in links/attachments—using API-based detection and automated remediation to remove threats quickly. That means fewer incidents and account takeovers, less noise for users and the SOC, faster investigations with unified quarantine/forensics, and clearer reporting for compliance. Net result: higher user confidence, lower risk, and shorter mean time to detect and respond.

  ### 18. Excellent Email Security Platform

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Retail | Enterprise (> 1000 emp.)

**Reviewed Date:** June 03, 2025

**What do you like best about Sublime Email Security Platform?**

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.

**What do you dislike about Sublime Email Security Platform?**

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.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime helps us address the ongoing challenge of advanced phishing attacks. It has reduced our workload by automatically detecting and quarantining threats, allowing us to focus on other critical tasks.

  ### 19. Proactive and simplified email security

**Reviewed by:** Verified User in Entertainment | Enterprise (> 1000 emp.)

**Reviewed Date:** May 23, 2025

**What do you like best about Sublime Email Security Platform?**

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.

**What do you dislike about Sublime Email Security Platform?**

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.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Sublime has helped significantly enhance our email threat detection and response, by identifying sophisticated campaigns, automating rule logic, and integrating seamlessly with our SOAR, SIEM, and greater workflow. Overall, it's helped us shift from a more reactive approach to a more proactive stance on email security.

  ### 20. Best in the business for email security

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Education Management | Enterprise (> 1000 emp.)

**Reviewed Date:** May 21, 2025

**What do you like best about Sublime Email Security Platform?**

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.

**What do you dislike about Sublime Email Security Platform?**

There is not much to dislike about Sublime, it has worked since day one and has had a huge, positive impact for our organization.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Our previous email security solution would not identify novel phishing threats and would constantly allow malicious emails to land in user's inboxes. Since implementing Sublime and enabling the auto-quarantine feature, we have seen a drop in 60% of user reported phishing emails. Sublime is constantly catching and remediating emails long before the end user ever sees them.

**Reviewed Date:** May 21, 2025

**What do you like best about Sublime Email Security Platform?**

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.

**What do you dislike about Sublime Email Security Platform?**

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.

**What problems is Sublime Email Security Platform solving and how is that benefiting you?**

Building custom detections specific to our environment and allowing my team to automate processes via their API

  ### 23. The best security software I have used
