twistlock

Twistlock was a cybersecurity company specializing in container security for Docker and cloud-native applications. Its platform provided image scanning, runtime protection, and compliance enforcement across containerized workloads and cloud environments, including Kubernetes and major cloud providers.

Core capabilities included container image scanning for vulnerabilities and misconfigurations in registries, runtime defense to monitor and block malicious behavior at the host and container level, and policy-driven security across build and runtime stages, with centralized management and reporting.

Twistlock operated as an independent company before being acquired by Palo Alto Networks in 2019 for approximately $410 million. The acquisition integrated Twistlock technology into Palo Alto Networks' cloud security portfolio, ultimately becoming part of Prisma Cloud and expanding container and cloud workload protection with vulnerability management, compliance, and runtime defense features.
