Your containers aren’t isolated. Here’s why that’s a problem. microVMs, VMMs and container isolation.

In today's fast-paced tech environment, developers and AI agents are rapidly writing and deploying code, often using package managers like npm to include numerous dependencies with minimal scrutiny, which can inadvertently introduce security vulnerabilities. The widespread use of containers, often mistakenly seen as secure boundaries, further exacerbates the risk, as they share the host kernel, making them susceptible to container escapes that can compromise sensitive information and system access. To mitigate these risks, secure runtimes like gVisor and Kernel-based Virtual Machines (KVM) offer enhanced isolation by providing strong sandboxes that prevent untrusted code from affecting the host environment. These tools are critical for ensuring the security of multi-tenant services and workloads generated by AI or other automated systems, as they offer VM-level security within container workflows, thus protecting infrastructures from potential breaches. Organizations like Northflank leverage these technologies to provide secure runtime environments that isolate workloads effectively, ensuring robust protection against unauthorized access and lateral movement while maintaining efficient orchestration in cloud environments.
