Push Security is a Series A–funded Identity Threat Detection & Response (ITDR) vendor founded in 2021, headquartered in London with a North America HQ in Boston, serving a global market with current emphasis on the US, UK, and Central Europe. ITDR has become increasingly central to cybersecurity as identity becomes the effective “perimeter,” and attackers more frequently rely on phishing, credential theft, and other identity-driven techniques. In this context, Push Security is positioned as an innovative, fast-rising provider aiming to detect and respond to identity-based attacks through a differentiated telemetry strategy.
The company’s core approach uses browser telemetry to deliver identity discovery, monitoring, and threat detection across common browsers without requiring endpoint installation. This browser-centric visibility supports detection of techniques such as MFA-bypassing phishing kits, session theft, and credential stuffing, as well as behaviors like password reuse and interaction with malicious web applications. By correlating browser telemetry with endpoint, network, and log sources, the platform seeks to surface attack patterns that traditional ITDR tools may miss, while also complementing established security stacks.
Push Security emphasizes integration with SIEM and XDR platforms to enrich existing detection and response workflows with identity-relevant signals. Strengths include unique insights into user interaction and attack behavior, reduced deployment complexity, and applicability for both small organizations and large enterprises. Challenges include a primary focus on browser-based threats that may leave other ITDR areas less covered, lower brand recognition relative to established competitors, and the operational need for organizations to absorb and operationalize a new telemetry stream. The broader ITDR market is expected to grow and converge with SIEM/XDR ecosystems, with ongoing consolidation and movement toward unified identity protection platforms.
