Bit9 + Carbon Black was founded in 2002 and headquartered in Waltham, Massachusetts. The company specialised in endpoint security, developing solutions for threat detection and advanced persistent threat protection across organisational networks.
Bit9's original offering focused on application whitelisting and device control, providing comprehensive visibility into software running across endpoints. In 2014, Bit9 merged with Carbon Black, combining their technologies into an integrated endpoint threat prevention, detection, and response platform. The merged entity leveraged cloud-based threat intelligence and behavioral analysis to identify malicious activity in real time, enabling continuous monitoring of endpoint activity and rapid response to security incidents.
The company served a broad customer base spanning government agencies, Fortune 1000 enterprises, and various industries requiring robust cybersecurity protections. In 2019, VMware acquired Carbon Black, and the combined entity was subsequently rebranded as VMware Carbon Black, continuing to offer next-generation endpoint security solutions.
