The Container and Kubernetes Security segment refers to technologies and solutions designed to protect containerised applications and Kubernetes environments from vulnerabilities, cyber threats, and configuration errors. Containers and Kubernetes orchestration are widely used in modern software development and deployment because they enable efficient scaling, portability, and faster release cycles. However, they also introduce unique security challenges related to runtime protection, access control, image integrity, and vulnerability management — areas that specialised security tools aim to address.

A central focus of Container and Kubernetes Security solutions is safeguarding container images and environments throughout the application lifecycle. This includes scanning container images for known vulnerabilities before deployment, enforcing security policies, and ensuring that only trusted images are used in production. By identifying weaknesses early in the development process, organisations can reduce the risk of exploitable flaws reaching live environments. These practices are critical for minimising risk in cloud-native applications that depend on microservices and frequent updates.

In Kubernetes environments, security tools help enforce proper configurations and access controls. Kubernetes manages application deployment, scaling, and networking across clusters of servers, but misconfigurations or insecure defaults can create attack surfaces that cyber threats can exploit. Security platforms provide capabilities such as role-based access control (RBAC), network segmentation, and admission control policies to limit unintended access and lateral movement within clusters. Continuous monitoring and alerting further help detect unusual activity or potential breaches.

Runtime protection is another important aspect of Container and Kubernetes Security solutions. Security tools observe container behaviour in real time, detecting anomalies, suspicious processes, or unexpected communication patterns that could indicate an attack. When threats are identified, these systems can trigger alerts, isolate affected containers, or execute automated responses to mitigate impact. This level of monitoring helps organisations maintain resilience even when threats evolve rapidly.

Compliance and audit capabilities are also integrated into many container security tools. Organisations must often adhere to regulatory standards and internal governance frameworks that require visibility into changes, configurations, and access events. Security solutions provide audit trails, reporting, and policy enforcement to ensure compliance with industry best practices and regulatory requirements. These features support both security teams and organisational leadership in maintaining accountability.
