Company Overview

About Transmit Security

Transmit Security is an enterprise cybersecurity company specializing in customer identity and access management (CIAM). Founded in 2014, the company offers a unified platform that integrates identity orchestration, passwordless authentication, fraud detection, and identity verification into a single developer-friendly API suite. Its low-code orchestration engine allows enterprises to design and automate complex identity journeys — such as step-up authentication, account recovery, and progressive profiling — without rebuilding authentication from scratch.

Business Model & Competitive Advantage

The company raised $543M in a Series A round in June 2021 — the largest Series A in cybersecurity history — reflecting the strategic importance of CIAM as enterprises shifted from siloed authentication tools to unified identity platforms. Transmit Security exceeded $100M in annual recurring revenue and grew revenue 40% year-over-year in the first half of its post-funding period, while expanding its customer base 51%. It serves many of the world''s largest banks, insurers, and global retailers, whose customers collectively transact more than $2 trillion in annual commerce through Transmit-secured experiences.

Competitive Landscape 2025–2026

Transmit Security was recognized as a Leader in the 2025 Gartner Magic Quadrant for Access Management and the Forrester Wave for CIAM Q4 2024. The platform competes with Okta Customer Identity Cloud, Ping Identity, and ForgeRock in the enterprise CIAM segment. Its key differentiators include native fraud detection (not bolted on), AI-driven risk scoring integrated directly into authentication flows, and an orchestration layer that lets identity teams manage journeys without engineering bottlenecks. Transmit is headquartered in Boston with R&D and operations in Israel.
