In modern software development, particularly with cloud-native and container-based applications, security is a critical factor. Vulnerabilities in container images, dependencies, and Infrastructure as Code (IaC) configurations can lead to significant risks. To identify and address these vulnerabilities, various tools are available. Three of the most well-known and widely used tools in this space are Grype, Aqua Trivy, and Snyk.
In this post, we compare these three tools, highlighting their strengths, weaknesses, and use cases to help you decide which tool best fits your security needs.
