25 Open-Source Cybersecurity Tools for Teams on Any Budget
Summary
A roundup of 25 open-source tools for security automation, AI-agent governance, secrets scanning, cloud and pipeline audits, monitoring, forensics, and incident response.
Key points
- Allama and ShipSec Studio provide visual workflow orchestration for security operations.
- Asqav signs AI-agent actions and links them in a hash chain; Sage intercepts agent operations, while Scenario automates red-team exercises.
- Betterleaks scans repositories, directories, and standard input for exposed credentials; Conjur manages application secrets and identity.
- Cloud-audit scans AWS environments and provides remediation guidance; Plumber checks GitLab CI/CD configurations for compliance gaps.
- CERT UEFI Parser supports analysis of UEFI software, while mquire analyzes Linux memory dumps without external debug information.
- OpenClaw Scanner detects autonomous AI agents in corporate environments; SecureClaw adds auditing and rule-based controls for agent environments.
