Sublime Security
Agentic email security for enterprise BEC and targeted phishing
Sublime is the right call for mature security teams that want to cut the busywork on BEC and targeted phishing without losing visibility. The two AI agents genuinely automate triage and rule authoring, and the evidence-backed verdicts give you auditable decisions—something black-box gateways can't match. But if you don't have in-house detection engineers to review auto-generated rules, the value fades fast; look at Proofpoint or Abnormal Security instead.

Skip Sublime Security if you don't have in-house detection engineering expertise to review and tune AI-generated rules, or if you're seeking a fully managed, set-and-forget email security solution.
Pricing is contract-only, so you can't evaluate cost without a sales call, and there may be a minimum contract commitment.
Pricing is custom and contact-based, which fits enterprises that already have detection engineering resources and want to negotiate based on volume. For smaller teams, the lack of transparent tiers may feel prohibitive compared to per-user pricing from Proofpoint or Abnormal Security, which publish list prices.

About Sublime Security
Sublime Security helps enterprise security teams take control of email threats like business email compromise (BEC), vendor email compromise (VEC), credential phishing, and callback phishing. Instead of relying on a static gateway, the platform uses two AI agents: the Autonomous Security Analyst (ASA) triages user-reported emails automatically, while the Autonomous Detection Engineer (ADÉ) authors custom detection rules tailored to your organization within hours. That combination shifts your SOC from repetitive triage to handling threats that require human judgment. A defining feature is full transparency: every detection decision comes with evidence-backed verdicts, so analysts can see exactly why an email was flagged. Legacy gateways like Proofpoint or Mimecast often behave as black boxes, but Sublime positions itself as the auditable alternative. Custom detection rules are written in Sublime Script, a YARA-like language, letting in-house teams translate their knowledge of their attack surface into precise, testable detections. A dedicated threat hunting interface supports proactive investigation, and native integrations with Microsoft 365 and Google Workspace mean the platform works where your mail already lives. Sublime reports operational gains that matter to lean SOCs: 80% faster user report investigation, 30% fewer false positives than other API-based email security solutions, and up to 70% reduction in false positives overall. A free EML Analyzer handles ad-hoc email analysis for quick lookups. In July 2026, the company launched advanced graymail protection into public beta, which tackles bulk and newsletter noise so analysts can stop drowning in marketing messages that aren't real threats. For organizations with in-house detection engineering talent, Sublime offers adaptive coverage without the vendor bottleneck from managed detection teams. It's not a set-and-forget solution; it rewards teams that invest in writing and tuning custom rules. If you lack
Behind the Verdict
Sublime isn't for everyone, and that's fine. If your team has detection engineers who can write and tune rules, this is one of the few email security tools that lets you turn your own threat knowledge into precise detections. The ADÉ agent speeds up rule authoring, but you still need to review what it produces—this platform rewards teams that treat detection as an ongoing practice, not a one-time setup. Where it really shines is cutting through the noise. The evidence-backed verdicts mean your analysts spend less time second-guessing alerts and more time on real threats. Legacy gateways like Proofpoint or Mimecast often leave you with black-box decisions; Sublime gives you a clear view of why something was flagged, which is huge for audits and for building trust in your security operations. The new graymail protection in public beta is a welcome addition. If your analysts are drowning in newsletter and bulk email alerts, that feature alone could save hours each week. It's still beta, so expect some rough edges, but it shows Sublime is listening to real SOC pain points. When should you pass? If you have no in-house detection talent, the core value fades. Auto-generated rules still need human review, and without that expertise, you might end up with a platform you can't fully leverage. Likewise, if you only need basic spam filtering, this is overkill—you'd be paying for depth you'll never use. Compared to managed competitors like Abnormal Security or Proofpoint, Sublime is the DIY, high-control option. Those alternatives are easier to adopt but lock you into their detection logic. Sublime gives you the keys, but you have to know how to drive. If you've been burned by vendor bottlenecks and want to own your detection stack, it's worth a close look. In practice, we'd

Real-world workflow fit
Concrete scenarios for the personas Sublime Security actually fits — and what changes day-one when you adopt it.
A user forwards a suspicious email that might be a BEC attempt. The analyst submits it to Sublime, and the ASA agent automatically triages it, pulling headers and content, and assigning a risk score with evidence.
Outcome: The analyst reviews the evidence-backed verdict, determines it's a BEC attempt, and initiates automated quarantine and alerting—cutting investigation time by 80%.
The team wants to detect a newly observed VEC pattern targeting their finance team. The engineer uses the ADÉ agent to auto-author a custom detection rule in Sublime Script, then tests it against historical email data.
Outcome: The rule goes live within hours, providing adaptive coverage without waiting for a vendor-managed update.
Use Cases
- Detect and block business email compromise attacks in real-time
- Automate incident response for account takeover alerts
- Write custom detection rules for vendor email compromise scenarios
- Prioritize phishing alerts using machine learning triage
- Investigate email threats with full header and content visibility

Where the pricing makes sense
The company stage and team size where Sublime Security's pricing actually pencils out — and where peers do it cheaper.
Pricing is custom and contact-based, which fits enterprises that already have detection engineering resources and want to negotiate based on volume. For smaller teams, the lack of transparent tiers may feel prohibitive compared to per-user pricing from Proofpoint or Abnormal Security, which publish list prices.
Setup time & first value
How long it actually takes to get something useful out of Sublime Security — broken out by persona, not the marketing-page minute.
For a SOC analyst, basic setup with Microsoft 365 or Google Workspace integration can take less than a day to start triaging user-reported emails. Writing custom rules with Sublime Script may take a few days to a week depending on complexity and team experience.
