Service Mesh vs API Gateway: Security Implications

Leave a Comment / Infrastructure /

Security should move at the speed of your pipeline. As organizations modernize with Kubernetes and microservices, two key components often appear in the architecture: the API gateway and the service mesh. Both handle communication, but their security responsibilities differ. Understanding where each control fits prevents gaps in protection and avoids overlapping complexity. What Is an […]

Kubernetes API server request flow with admission controllers enforcing security policies

Kubernetes Admission Controllers: Security Use Cases – Complete Guide

Leave a Comment / Infrastructure /

Security should move at the speed of your pipeline. When teams scale to multiple clusters, visibility gaps grow fast — so embedding preventive controls directly into your Kubernetes API layer becomes critical. In practice, admission controllers serve as security gatekeepers that intercept API requests before persistence, enabling policy enforcement, validation, and mutation of resources. As

Container Supply Chain Security: Image Signing and Verification

Leave a Comment / Cloud Security /

In the modern CI/CD pipeline, the container is the new currency of deployment. But just like any currency, it can be counterfeited. A maliciously altered base image, a library with a hidden vulnerability, or a tampered application layer can introduce critical risks into your environment the moment you run docker pull or kubectl apply. Securing the container supply

Securing Serverless Functions Security should move at the speed of your pipeline. Serverless computing accelerates development by removing infrastructure management, but it also introduces new attack surfaces. Functions run with high privilege by default, generate ephemeral logs, and depend heavily on third-party triggers. This guide explains the security challenges of serverless functions, compares AWS, Azure,

Illustration of multi-tenant Kubernetes cluster with security isolation between tenants.

Multi-Tenant Kubernetes Security Challenges

Leave a Comment / Cloud Security /

When teams scale to multiple clusters, visibility gaps grow fast. Kubernetes was designed for flexible container orchestration, but in multi-tenant environments, security risks multiply. Enterprises that run multiple teams or customers in the same cluster face isolation, identity, and compliance challenges that go beyond single-tenant setups. This article explains the most pressing multi-tenant Kubernetes security
