Dow Jones Hammer is a multi-account cloud security tool for AWS. It identifies misconfigurations and insecure data exposures within most popular AWS resources, across all regions and accounts. It has near real-time reporting capabilities (e.g. JIRA, Slack) to provide quick feedback to engineers and can perform auto-remediation of some misconfigurations. This helps to protect products deployed on cloud by creating secure guardrails. Documentation Dow Jones Hammer documentation is available via GitHub Pages at https://dowjones.github.io/hammer/.
