Dockle vs Sysdig Secure

Dockle is a free, self-hosted container image linter focused on security and Docker best practices. It scans images for vulnerabilities and checks settings against CIS Docker Image Benchmarks, along with Docker- and Linux-specific issues such as empty passwords and duplicate user or group IDs. Results can be displayed or saved in JSON and SARIF formats. Users can set an exit level and ignore selected checkpoints through command options, environment variables, or a .dockleignore file. The project documents continuous-integration use and provides a GitHub Action, with examples for Travis CI, CircleCI, and GitLab CI. Dockle can access private images in Docker Hub, Amazon ECR, Google Container Registry, and self-hosted registries. It can also scan an image archive created with docker save by using the --input option. Installation routes include Homebrew, Linux distribution packages, Windows binaries, version managers, source builds, and Docker. Dockle runs on Linux, macOS, and Windows and is listed under the Apache-2.0 license.

Sysdig Secure is a cloud-native application protection platform for cloud environments, containers, Kubernetes, hosts, and serverless workloads. It uses runtime insights to prioritize risks that are exploitable in a customer’s environment. Threat detection runs in real time using Falco rules, machine learning, and drift control; vulnerability scanning is available with agent-based or agentless approaches and prioritizes vulnerabilities in use. Cloud Attack Graph connects vulnerabilities, misconfigurations, and excessive permissions to map potential attack paths. Sysdig Sage is an AI assistant for security search, vulnerability management, threat investigation, and response. The platform connects to AWS, GCP, and Azure, and documents integrations including Git, Jira, Snyk, Docker Scout, Splunk, Elasticsearch, and Syslog. Sysdig describes support for on-premises, air-gapped, and private cloud environments. Deployment is hybrid, with licensing based on hosts or compute instances for CSPM. The documented agent supports Linux distributions and Windows Server 2019 and later; the vulnerability CLI scanner is available for Linux and macOS. Pricing is by quote rather than displayed.
