Ideal Customer
- Sublime Security primarily targets enterprise security teams, with its own positioning explicitly stating it builds 'email security for the organizations that can least afford to get it wrong — enterprises with complex environments, high-value targets, and zero tolerance for disruption.' Representative enterprise customers include Spotify, Snowflake, Zscaler, Elastic, Anduril, and Ramp, indicating a sweet spot among technology-forward companies with mature security operations centers (SOCs).
- The platform also serves mid-market organizations effectively, particularly through MDR and MSSP partners such as At-Bay, which uses Sublime to deliver enterprise-grade email protection to its mid-market and SMB insured base.
Key Differentiators
- Sublime Security's core differentiator is its 'Distributed Detection Model' (DDM) — instead of applying a one-size-fits-all global detection ruleset, it generates and tunes detection coverage specific to each customer's email environment, closing organization-specific blind spots that centralized models leave open.
- Its proprietary Message Query Language (MQL) enables Detection-as-Code: transparent, human-readable, auditable detection rules that security teams can write, backtest against historical email data, and deploy — a capability compared to Sigma/YARA/Snort but purpose-built for email.
Industries Served
- Sublime Security's website explicitly highlights Financial Services, Education, and SaaS/Technology as its primary named verticals, with dedicated landing pages and marketing for each.
- Healthcare is also a demonstrated vertical — Coronis Health, a healthcare revenue cycle management company handling PHI as a HIPAA business associate, is a featured customer case study.
Service Coverage
- Sublime Security is headquartered in Washington, D.C. and operates as a global SaaS platform serving customers across North America, Europe, and Asia.
- Its workforce is concentrated predominantly in North America (approximately 91%) with a growing presence in Northern Europe (approximately 9%), and the company has stated its intent to expand its global reach following its Series C funding.
Partnerships
- Sublime Security operates a formal, 100% channel-led go-to-market model launched in April 2026, under VP of Worldwide Partners & Alliances Timm Hoyt (previously at Sumo Logic, Druva, and PagerDuty).
- The partner program includes Reseller, MSP/MSSP/MDR, and Technology Alliance tiers, with named partners including GuidePoint Security, Myriad360, Bytes Software Services (UK), Nomios (Europe), and Black Hills InfoSec.
Company Size & Ownership
- Sublime Security was founded in 2019 by Josh Kamdjou (CEO) and Ian Thiel (COO), and has grown rapidly from approximately 19 employees in 2023 to roughly 296–308 employees as of mid-2026 — a headcount increase of nearly 1,490% over three years.
- ZoomInfo estimates annual revenue at approximately $66.6 million, while LeadIQ's estimate ranges more broadly at $500M–$1B (likely reflecting ARR run-rate projections post-Series C); the company reported 100% growth in annual recurring revenue in the first half of 2025 alone.
Compliance & Certifications
- Sublime Security maintains a public Trust Center (trust.sublime.security) documenting its internal security controls, which reflects a security program built by former offensive security professionals with multiple control layers including data encryption at rest, portable media encryption, code of conduct enforcement, and contractor confidentiality requirements.
- The company has not publicly announced FedRAMP authorization; however, it acknowledges FedRAMP and self-hosting requirements as use cases its platform is designed to accommodate, including a self-hostable Docker deployment option for regulated customers.
