Bit9

Bit9 is a cybersecurity company known for its focus on endpoint protection and application control. The core offering centers on preventing untrusted software from executing by enforcing allowlists of approved applications, drivers, and services, while monitoring endpoint activity for signs of misuse. The approach combines on‑device enforcement with cloud‑based reputation data and centralized policy management, enabling administrators to define rules for software installation, execution, and device usage.

Bit9 technologies emphasize prevention through strict application control and code integrity, supplemented by visibility into software inventory and security events. The platform typically supports integration with incident response workflows and can feed data into security information and event management systems, aiding detection, investigation, and compliance efforts. Because of its emphasis on trusted software baselines, Bit9 has been described as an early adopter of application allowlisting, a strategy that has influenced later endpoint protection and integrity solutions.

Over time, Bit9’s solutions have become part of broader enterprise security offerings through partnerships and integrations within the cybersecurity landscape. The company’s work in application control, file reputation, and endpoint governance has contributed to ongoing conversations about prevention-centric security models in modern networks.
