Developer security tools are easy to buy and hard to choose. Code scanners (SAST), dynamic testing of running apps (DAST), container and dependency scanners and infrastructure-as-code checks each catch different problems, and most teams need more than one. This page brings together every security scanner comparison and guide on the site.
A sensible order for a small team: scan dependencies and container images in CI first, add static analysis on pull requests, check Terraform and Kubernetes files before they are applied, then add dynamic testing against a staging environment. The comparisons below look at what each tool detects, how noisy it is, how it fits a pipeline and what it costs.
How to choose developer security tools
Start with what you ship
If you ship containers, an image scanner gives the fastest return: it finds known vulnerabilities in base images and packages with almost no setup. Open-source scanners such as Trivy and Grype are good enough for most teams; the open-source container scanners guide and Trivy vs Grype vs Snyk compare them.
Know the three kinds of testing
SAST reads your code, DAST attacks the running application and IAST watches it from the inside while tests run. They overlap less than vendors suggest, which is why the DAST vs SAST vs IAST comparison is worth reading before buying anything.
Watch the noise
The best developer security tools are the ones people do not learn to ignore. Measure false positives on your own code before rolling a scanner out to every repository, and prefer tools that can fail a build only on new, high-severity findings. The Snyk review and Snyk vs GitHub Advanced Security look at this in practice.
Cloud platforms
Once workloads run across several cloud accounts, a cloud-native application protection platform (CNAPP) gives one view of misconfigurations and exposed assets. These are expensive, so compare carefully: Wiz vs Prisma Cloud and the Wiz alternatives cover the main options.
A sensible starting stack
For a small team: an open-source image and dependency scanner in CI, static analysis on pull requests, an IaC checker for Terraform, and a scheduled DAST scan of staging. Add a commercial platform only when you can name the gap it fills. The guides on this page help you choose developer security tools that catch real problems without slowing every merge.
