Deepfence SecretScanner review
A focused open-source scanner for secrets across containers, directories, and host filesystems.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Deepfence SecretScanner is an open-source tool for detecting exposed secrets in container images, local directories, and host filesystems. It is aimed at security teams, developers, and operators who need a focused scanner for deployed or locally accessible content. Its detection coverage includes passwords, API keys, encryption keys, SSH keys, and tokens, matched against approximately 140 secret types. The tool runs as a Docker container and is available for Linux and self-hosted environments.
Pricing is straightforward: SecretScanner is open source, with no paid plan structure described. The published capabilities center on scanning container images, directories, and host filesystems, then emitting findings in JSON. Configurable excluded extensions and paths help teams narrow scans around their environment and reduce unwanted coverage. SecretScanner can also be used within Deepfence ThreatMapper, giving teams using that platform a broader place to incorporate the scanner. Docker support makes containerized execution part of the operating model rather than an optional integration layer.
SecretScanner’s main strength is its narrow, practical focus: it combines container and filesystem coverage with recognizable secret categories and machine-readable output. That makes it a fit for teams building scanning into Linux or self-hosted security workflows, particularly where JSON findings can feed downstream processes. Its scope is less suited to teams whose primary workflow is repository management, pull requests, pre-commit checks, or push protection. Those teams should choose a repository-focused alternative. Pick SecretScanner when container images and filesystems are the assets you need to inspect; look elsewhere when source-control workflow features are central.
