Tigera: Default vs. Third-Party Kubernetes Networking Stacks: A Technical Evaluation

Native networking tools provided by Kubernetes vendors are standard “Day 1” choices because they are pre-installed and free. However, as clusters scale, these default stacks often lack the deep Layer 7 visibility, advanced micro-segmentation, and egress controls required for production security.

This webinar helps platform teams evaluate the architectural trade-offs between utilizing the “out-of-the-box” networking stack versus adopting a specialized third-party platform.

• What is good enough?: Analyzing where native tools (VPC CNI) reach their limits?
• Security Islands: Challenges in Managing Fragmented Security Models
• Distro Dependency: How relying on bundled networking creates lock-in that prevents consistent operations across other environments
• Advanced Capabilities: Evaluating critical features often missing from default stacks, including granular egress controls and deep packet inspection.
