Sublime Security
Agentic email security that triages reported phishing and writes backtested Sublime Script detections
Buy Sublime if reported-phishing volume is eating your detection engineers alive and you want detections you can read and tune. ASA plus ADÉ target the exact hours that hurt, and visible evidence beats a risk score every time. Pass if nobody on the team can own a detection-review queue, because the transparency becomes work rather than relief.

Skip Sublime if you want a set-and-forget filtering appliance and have nobody on staff to review, approve and tune detections in Sublime Script.
Every new detection waits for a human click, so the real cost is analyst hours for review and approval, not just the licence.
Sublime is scoped and quoted per engagement rather than sold as a published self-serve tier, which puts it in the same buying motion as enterprise email security platforms and above per-mailbox SEG list pricing. The free analyzer and analyzer API let you test detection quality on real messages before any budget conversation.

About Sublime Security
Sublime Security aims at the piece of email security nobody wants to staff: the abuse mailbox. User-reported phishing arrives all day, and for most enterprise SOC and detection-engineering teams it becomes a second job on top of the first. Sublime runs specialist AI agents on that work instead of collapsing each report into a score you can't inspect. The Autonomous Security Analyst (ASA) takes a report from intake through to a verdict, and the Autonomous Detection Engineer (ADÉ) authors new detections matched to your environment, backtests them, and holds them for one-click approval before they go live. The vendor claims 80% faster user-report investigation and a 70% cut in false positives. Every verdict ships with its matched detections, signal analysis, and supporting evidence, so an analyst can trace why a message was flagged. Detections are written in Sublime Script, a YARA-like language your engineers can read, test, and tune, backed by a behavioral threat-hunting interface and automated quarantine, alert, and remediation actions. Coverage runs from BEC and vendor email compromise through credential, callback, QR code, and ICS phishing, plus prompt injection and malware or ransomware in email. Email DLP is generally available, and advanced graymail protection entered public beta in July 2026 to separate bulk noise from real reports. Tailored phishing simulations and training went GA in October 2026. It deploys natively over Microsoft 365 and Google Workspace, and a free analyzer plus analyzer API lets you scan suspicious messages before any rollout. Set against legacy secure email gateways, Sublime trades opaque scoring and set-and-forget filtering for a detection-engineering workflow your team owns. It reads closer to an open detection platform than a filter appliance: you buy authorship and evidence, not a black box.
Behind the Verdict
The reported-phishing queue is where email security tooling usually goes to die. Legacy gateways throw a score at you and move on; your analysts rebuild the reasoning by hand, message by message. Sublime's bet is that agents can do the first pass and show their work. In practice that means ASA reads a report, matches it against detections, and hands back evidence an analyst can check in seconds rather than minutes. We'd reach for this when you already have detection engineers who want to own rules. ADÉ authors org-specific coverage, backtests it against your mail, and waits for a human to approve. That last step matters. The vendor sells hours-not-months coverage, and the backtest gate is what keeps that from being a firehose of unvetted rules. Where it bites is staffing. If your security team is one or two people, a review queue with a backtest step is homework you won't finish. Teams that want a set-and-forget appliance should look elsewhere, and shops that only need basic spam and malware filtering will pay for machinery they never touch. The closest mental model isn't another SEG vendor; it's an email detection platform you configure. Sublime Script is the product, not a side feature. The free analyzer and analyzer API are the honest way to test that premise before committing budget. Start there, scan a week of real reports, and see whether the evidence output actually shortens your analysts' day. One caveat on the numbers: the 80% faster investigation and 70% false-positive reduction come from Sublime's own customer stories, not independent benchmarks. Treat them as direction, not a contract. And the roadmap moves fast (graymail beta in July 2026, phishing simulations GA in October 2026), so pin down what's GA versus beta before you consolidate tools on it.

Real-world workflow fit
Concrete scenarios for the personas Sublime Security actually fits — and what changes day-one when you adopt it.
A user reports a suspicious invoice email. ASA pulls the message, runs the detection library, assembles the matched detections and signal analysis, and returns a verdict with evidence attached.
Outcome: The analyst reviews a readable verdict instead of rebuilding the investigation from headers, and the message is quarantined through an automated response action.
ADÉ spots a gap in coverage against vendor email compromise patterns in your environment, drafts a Sublime Script detection, backtests it against historical mail, and queues it for review.
Outcome: The engineer approves or edits one detection in a click rather than writing YARA-like rules from scratch, and the new detection goes live with a tested false-positive profile.
You run real reported messages through the free analyzer and the analyzer API to see how Sublime's detections score against your current stack.
Outcome: You get a concrete read on detection quality and false-positive rate on your own mail before committing to a rollout.
Use Cases
- Automate triage of user-reported phishing from intake to verdict
- Generate and backtest detections tuned to your own mail environment
- Investigate BEC and vendor email compromise with evidence-backed verdicts
- Audit exactly why a message was flagged using matched detections and signal analysis
- Quarantine and remediate threats automatically after analyst approval
- Hunt for behavioral patterns across email with a threat-hunting interface
- Filter bulk and newsletter noise out of the abuse queue with graymail protection
- Scan a suspicious message ad-hoc with the free analyzer before a rollout
Models Under the Hood

Limitations
- Sublime Security requires technical expertise to write and maintain custom detection rules in Sublime Script.
- The payoff scales with the tuning effort you invest, so teams without dedicated detection-engineering staff will extract far less.
- Set-and-forget filtering is not what this product is built to be.
- The vendor's efficiency figures (80% faster investigation, 70% fewer false positives) are its own comparisons against a replaced stack, not independent benchmarks.
- Advanced graymail protection is still in public beta as of July 2026.

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.
Sublime is scoped and quoted per engagement rather than sold as a published self-serve tier, which puts it in the same buying motion as enterprise email security platforms and above per-mailbox SEG list pricing. The free analyzer and analyzer API let you test detection quality on real messages before any budget conversation.
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.
Analysts get value the day reported messages start flowing into ASA, since verdicts arrive with evidence attached. Detection engineers need longer — expect a working session to learn Sublime Script syntax and the approval queue. Teams on Microsoft 365 or Google Workspace deploy natively rather than through a gateway swap.
Switching to or from Sublime Security
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a legacy secure email gateway: run reported messages through the free analyzer first to compare detection quality, then move triage to ASA while keeping the gateway in monitor mode.
- →From Microsoft 365 native filtering alone: deploy natively over the tenant and route the abuse mailbox into ASA so reported phishing gets an evidence-backed verdict.
- →From Google Workspace native filtering alone: deploy natively over the Workspace tenant and start with ADÉ-generated detections before writing Sublime Script rules by hand.
- ↗To a legacy secure email gateway: export your Sublime Script detection logic first — the rule library is the asset you'd lose, and gateway vendors express the same intent as opaque policy settings.
- ↗To a managed detection service: hand over the verdict evidence trail and detection inventory so the new provider inherits your tuned false-positive profile.

Choose Multifactor if you need secure credential sharing with teams or AI; choose Sublime if you're a security team battling advanced phishing attacks. They are not direct competitors.
Aura vs Sublime Security
Choose Aura if you want an all-in-one family safety suite covering identity, device, and parental controls; it's a bundled approach with credit monitoring and VPN. Choose Sublime Security if your primary need is advanced email threat detection (BEC, phishing) with custom rules and low false positives, requiring a dedicated security team. They serve different markets and rarely overlap.
Bylaw vs Sublime Security
Choose Bylaw if you build AI agents that perform sensitive business actions and need to prevent decisions based on stale or conflicting evidence. Choose Sublime Security if your priority is defending against advanced email threats like BEC and VEC with custom detection rules. They solve entirely different problems, so your use case dictates the choice.
Openbrowserclaw vs Sublime Security
Sublime Security and Openbrowserclaw serve completely different needs: one is a paid enterprise email security platform for advanced threat detection, the other is a free client-side AI assistant for personal productivity. Choose Sublime if you're a security team combating BEC/phishing; choose Openbrowserclaw if you want a privacy-focused local AI for browsing and coding without any cost.
Vibeguard vs Sublime Security
Choose VibeGuard if you're a developer using AI coding assistants and need a free, open-source way to prevent sensitive data leaks without complex setup. Opt for Sublime Security if you're a security team in a mid-to-large enterprise facing advanced email threats and need AI-driven detection with low false positives. They solve completely different problems—privacy for AI coding vs. email security.
Atomic Agent vs Sublime Security
Choose Atomic Agent for local, private, autonomous task automation without cloud dependency — ideal for developers. Choose Sublime Security if you need enterprise-grade AI email security to combat BEC, VEC, and phishing with low false positives. They serve completely different needs.
Android Mobile Security Sandbox Testing vs Sublime Security
These two products don't compete — they're aimed at different security disciplines entirely. If you test Android apps manually and want a repeatable Magisk/Burp/Objection sandbox in minutes, JAMBOREE is the free answer. If you run an enterprise SOC drowning in user-reported phishing and want agentic triage plus custom detections, Sublime Security is the enterprise purchase. Buying one tells you nothing about whether you need the other.
Aperture vs Sublime Security
Aperture and Sublime Security solve completely different problems. Aperture is for hiring teams wanting to replace resume screening with evidence-based, fraud-proof behavioral interviews. Sublime is for security teams needing an AI email gateway to stop BEC and phishing. Choose based on your pain point: applicant volume vs. email threats.
Duck Ai vs Sublime Security
Duck.ai and Sublime Security are not competitors; they serve entirely different needs. Duck.ai is a free, privacy-focused AI chat service ideal for individuals who want anonymous AI interactions without logging. Sublime Security is an enterprise-grade email security platform for combating advanced phishing and BEC attacks. Choose based on your need: personal privacy vs. organizational email protection.
Hcaptcha vs Sublime Security
These tools serve completely different categories: hCaptcha protects against bots and fraud on websites, while Sublime Security defends against email threats. A buyer should choose based on their primary attack vector. If you need bot and fraud mitigation with privacy compliance, hCaptcha is the clear choice. For email security against BEC and phishing, Sublime is specialized, but its pricing is opaque.
Moltis vs Sublime Security
Moltis and Sublime Security serve entirely different needs. Moltis is a free, self-hosted AI agent for developers who want full control, multi-channel automation, and privacy. Sublime Security is a commercial email security platform for enterprise security teams battling advanced phishing and BEC.
