Transmit Security

Transmit Security is a cybersecurity firm with its headquarters located in Israel. The company specializes in providing authentication and identity verification solutions for organizations. Its platform enables businesses to verify users without relying on traditional passwords. Services are delivered through programmable interfaces such as APIs and SDKs. These tools are intended to be embedded directly into customer‑facing and internal applications.

Transmit Security’s technology emphasizes passwordless authentication methods, including biometric verification, magic links, and hardware‑based tokens. It also offers multi‑factor authentication that combines something the user knows, has, and is. A risk‑engine continuously evaluates contextual signals such as device reputation, location, and behavior to adjust authentication strength in real time. The system is designed to provide seamless user experiences while meeting strong authentication requirements. Developers can integrate the services using the provided SDKs for mobile, web, and desktop environments.

The firm’s primary market includes major financial institutions, reflecting a focus on sectors with stringent regulatory and security demands. By addressing compliance frameworks such as PSD2, GDPR, and various banking security standards, Transmit Security positions itself as a provider of regulated‑grade authentication. Its adaptive risk approach helps organizations balance security with usability, a consideration that is especially relevant in high‑volume consumer banking applications. The company’s solutions are marketed as reducing fraud and account takeover while lowering friction for legitimate users. This sector specialization informs its product roadmap and feature prioritization.

In February 2020, attackers gained access to Transmit Security’s file‑sharing system, which is used to distribute software components to clients. The breach exposed over a thousand email addresses, phone numbers, and other contact information, along with internal communications and binary files. The company publicly disputed claims that passwords were compromised and asserted that no proprietary source code was leaked. It also confirmed that client application data remained unaffected by the incident. Following the discovery, Transmit Security shut down the compromised file‑sharing service and undertook a forensic review. The episode highlighted the importance of securing distribution channels even for providers of authentication technology.
