About
Sublime Security is a next-generation email security platform that leverages autonomous AI agents to protect organizations from phishing, business email compromise (BEC), malware, callback phishing, QR code phishing, and other advanced email-based attacks. Unlike legacy solutions that rely on static, opaque detection methods, Sublime deploys a team of specialized AI agents that automatically adapt defenses to each organization's unique threat landscape. Two core AI agents power the platform: ASA (Autonomous Security Analyst), which instantly triages user-reported emails and clears abuse mailboxes without manual analyst involvement, and ADÉ (Autonomous Detection Engineer), which proactively authors, backtests, and deploys new org-specific detections for emerging threats—often within hours of a novel attack being identified. The platform provides full transparency into every detection decision, including matched detections, signal analysis, and clear evidence—eliminating the black-box problem common to legacy email security vendors. Security teams can also deploy their own custom detection policies independent of vendor queues. Sublime is purpose-built for enterprise security teams, MSSPs, and detection engineers who need to reduce false positives, automate incident response, and operate faster than adversaries. Customers report 80% faster user report investigations, 30% fewer false positives compared to other API email security solutions, and over 70% lower email security spend through tool consolidation.
Key Features
- Autonomous Security Analyst (ASA): AI agent that instantly triages user-reported emails, clearing abuse mailboxes and freeing security analysts from repetitive manual triage work.
- Autonomous Detection Engineer (ADÉ): AI agent that proactively authors, backtests, and deploys org-specific threat detections for emerging attacks in hours—not months—with one-click analyst approval.
- Explainable Detections: Full transparency into every detection decision with matched detections, signal analysis, and clear evidence surfaced for every alert, eliminating black-box verdicts.
- Custom Detection Policies: Security teams can write and deploy their own org-specific detection rules without waiting on vendor queues, enabling true independence and tailored coverage.
- Broad Attack Type Coverage: Detects BEC, credential phishing, callback phishing, QR code phishing, malware, ransomware, ICS phishing, and email bombs across inbound email flows.
Use Cases
- Automating triage of user-reported phishing emails to clear abuse mailboxes without manual analyst effort
- Detecting and blocking business email compromise (BEC) and spear-phishing attacks targeting executives and finance teams
- Rapidly deploying org-specific detection coverage for novel email threats within hours of their emergence
- Consolidating multiple email security tools onto a single adaptive platform to reduce spend and operational complexity
- Empowering detection engineers to build, backtest, and deploy custom email threat detection policies at scale
Pros
- Autonomous AI Agents Reduce Workload: ASA and ADÉ eliminate manual triage and detection engineering tasks, delivering documented efficiency gains of up to 5x for security teams.
- Full Transparency and Explainability: Every detection is backed by visible signal analysis and evidence, enabling analysts to trust and act on results without second-guessing opaque verdicts.
- Rapid Adaptation to Novel Threats: New org-specific detections are authored and deployed within hours of a novel attack being identified, far outpacing traditional vendor update cycles.
- Proven Cost and Efficiency ROI: Customers report 70%+ lower email security spend via tool consolidation and 30% fewer false positives compared to competing API-based solutions.
Cons
- Enterprise-Focused Pricing: Sublime Security is designed for enterprise and mid-market organizations; pricing is not publicly listed and may be inaccessible for small teams or individuals.
- No Self-Serve Free Trial: Prospective customers must request a demo to evaluate the platform, with no self-service onboarding or publicly available free tier advertised.
- Email-Only Security Scope: The platform is specialized for email-based threats and does not extend coverage to endpoint, network, or other attack surface areas.
Frequently Asked Questions
What types of email threats does Sublime Security detect?
Sublime detects a wide range of threats including business email compromise (BEC), credential phishing, callback phishing, QR code phishing, malware, ransomware, ICS phishing, and email bombs, among others.
How does the Autonomous Detection Engineer (ADÉ) work?
ADÉ is an AI agent that monitors for emerging threats, authors new org-specific detection rules, backtests them against historical data, and presents them for one-click approval—delivering new coverage in hours rather than months.
Does Sublime Security integrate with existing email and security tools?
Yes, Sublime integrates with major email platforms via API and supports SOAR (M-SOAR) workflows, threat intelligence operationalization, and provides a full API for custom automation and integrations.
How is Sublime different from legacy email security solutions?
Legacy solutions use static, opaque detection that cannot adapt to AI-powered attacks and leave analysts with unexplained verdicts and high false positives. Sublime uses autonomous AI agents that provide explainable, org-specific, and continuously evolving defenses without vendor bottlenecks.
Can security teams write and deploy their own detection rules?
Yes. Sublime supports custom detection policies and detection engineering, allowing security teams to author and deploy org-specific rules independently without depending on vendor update queues.
