About Sublime Security

Sublime Security sells email security software that offers AI-powered protection against modern email threats. Sublime says legacy security solutions cannot keep up with AI-powered attacks. Sublime says a centralized detection model gives every customer the same blind spots and that updates take weeks or months. Sublime says its platform deploys a team of specialized AI agents that autonomously stop targeted attacks.[2][5]

Sublime names two agents. ASA, the Autonomous Security Analyst, triages, investigates and resolves user-reported emails in seconds. Sublime says ASA clears the queue and provides transparent verdicts with investigation logs. ADÉ, the Autonomous Detection Engineer, generates new org-specific detections, backtests them and deploys coverage in hours. ADÉ creates and backtests org-specific coverage, then proposes it for deployment with approval in a click.[2][10]

Sublime says its distributed detection model adapts coverage to the customer's environment and generates new defenses in hours. Sublime's Distributed Detection Model adapts with every message an organization sends and receives. Detection methods named by Sublime include natural language understanding, computer vision, file explosion and dynamic link analysis. Sublime recursively unpacks files, URLs and images to find hidden payloads, and decodes QR codes, extracts text with OCR and uses computer vision to spot phishing pages. Sublime groups related messages so analysts can investigate once and remediate across all affected mailboxes. Sublime supports threat hunting through historical email data using Sublime's detection language. Sublime can automatically quarantine, delete, or warn users the moment a threat is detected. Sublime finds and remediates malicious calendar invites (ICS phishing).[2][5][11]

Sublime applies the same detection engine that powers inbound protection to catch sensitive data before it leaves the environment. Sublime says built-in DLP detections cover personal, payment, health and credential data. Sublime says ASA investigates each flagged message and blocks confirmed violations before delivery. Sublime says teams can manage inbound and outbound email protection in one platform, with one detection engine and one console.[5][6]

Tailored Phishing Simulations and Training is a Sublime add-on that uses attacks detected in the customer's environment to prioritize and create relevant simulations. Sublime lets customers choose a Sublime-curated template, turn a malicious email detected in their environment into a simulation, or generate one from a scenario they describe. When employees click, Sublime delivers immediate, attack-specific training on the email and signals they missed.[7]

Sublime connects to Microsoft 365 or Google Workspace via API, with no MX record changes. Sublime offers multi-tenant SaaS, single-tenant SaaS, or self-hosted deployment, and self-hosting is available to Enterprise customers. In the Enterprise-only option, Sublime says the software runs in the customer's VPC, and Sublime provides updates but can never access the data. In the other option, Sublime runs the software in its own VPC and operates it like traditional SaaS. Sublime stores and manages detection rules in GitHub, and exposes REST APIs to integrate email security data into existing workflows and tools. Sublime sends enriched telemetry to a SIEM and triggers playbooks in a SOAR. Sublime ingests threat feeds, YARA signatures and indicators of compromise (IOCs). Sublime works alongside Microsoft Defender for Office 365, and works alongside Google Workspace.[5][10][11][12][13]

Sublime offers a plan that is free for individual security practitioners getting started on Sublime Cloud. Sublime sells a plan with the full platform, premium support and advanced controls. Snowflake observed a decrease in false positives and in the time spent managing email security after implementing Sublime. Elastic uses Sublime for email security. Sublime says US Signal strengthens email defense while simplifying operations. Josh spent 10 years in offensive cyber initiatives and red teaming in the private sector, and he started Sublime to build a product that would stop phishing, which was always the fastest way for him to gain access to a network.[2][5][6][7][8][11]
