Clair vs Deepfence ThreatMapper

Clair is free, self-hosted software that continuously scans container images for vulnerabilities in operating-system bases, installed packages, and programming-language components. Clients use its API to index images and match them against known vulnerabilities. Clair updates its vulnerability database as new issues appear and can reanalyze images without rereading their complete contents. It supports OCI Distribution and Docker v2 images, and lists RHEL, Alpine, Ubuntu, Debian, Oracle, Photon, and SUSE distributions, plus Java, Python, Golang, and Javascript. Deployment options include microservices, monolithic installations, CI pipelines, and disconnected environments. Clair can run as an indexer, matcher, notifier, or combo process. It uses PostgreSQL for persistence and is released as a Quay.io container, with the clairctl command-line tool among its artifacts. Clair runs on Linux, supports registry scanning, and is licensed under Apache 2.0. Runtime protection is not provided.

Deepfence ThreatMapper is a self-hosted security tool that discovers production workloads and ranks threats by exploit risk. It maps pods, containers, applications, and infrastructure, then generates runtime software bills of materials for running workloads and operating systems and checks them against multiple vulnerability feeds. It also detects exposed keys, tokens, and passwords in containers and host filesystems, and evaluates infrastructure settings against CIS, PCI-DSS, HIPAA, and other benchmarks. The Threat Graph links vulnerability, secret, and compliance findings with network flows, security groups, and live status. Its management console runs in containers on a Docker host or dedicated Kubernetes cluster, providing HTTPS administration and API automation. One console can manage different workload types across on-premise and cloud deployments. Documented integrations include Slack, PagerDuty, Jira, Splunk, ELK, Sumo Logic, and AWS S3; image-build scanning supports CircleCI, Jenkins, and GitLab. The project is free under the Apache 2 license. Windows Server support is experimental and not suitable for production use.
