vuls
Vuls is an agent-less vulnerability scanner written in Go that detects security issues across Linux, FreeBSD, containers, and other environments. It pulls from multiple vulnerability databases (NVD, OVAL, security advisories) and can run without root privileges or SSH in certain modes, making it suitable for continuous scanning in CI/CD pipelines.

What vuls is
Agent-less Go application that performs vulnerability assessment by querying installed packages against NVD, OVAL, and distribution-specific security advisories. Supports multiple scan modes (remote SSH, local, server/HTTP), can detect non-OS package vulnerabilities via lockfiles and CPE scanning, and integrates with GitHub and OWASP Dependency-Check.

Best use cases
Implementation considerations
- Choose scan mode based on environment: Fast Scan (no root, no agents) for minimal overhead; Fast Root Scan for process-level detection; Remote (SSH-based) for centralized management; Server/HTTP for air-gapped targets.
- Plan vulnerability database refresh strategy: offline mode requires pre-downloaded DB for CentOS, Debian, RHEL, Fedora, Ubuntu, Oracle Linux. Real-time scanning requires internet access to NVD, OVAL, and advisory feeds.
- Integrate SSH key management and network connectivity between Vuls scanner and remote targets; Server mode eliminates SSH but requires HTTP/HTTPS ingress from target systems.
- Configure output routing (email, Slack, TUI Viewer, Web UI via VulsRepo) and retention policy for scan results; no built-in patch management, so coordinate findings with separate change management workflow.
- Validate OS/distribution support: Alpine, Amazon Linux, CentOS, Alma, Rocky, Debian, RHEL, openSUSE, Fedora, Ubuntu, FreeBSD, Windows, macOS are listed; test with your specific OS versions before production rollout.
When to avoid it — and what to weigh
- You need automated remediation — Vuls explicitly does not update vulnerable packages; it only detects and reports. Requires separate orchestration for patch deployment.
- GPL-3.0 incompatible with your license strategy — GPL-3.0 requires derivative works to be open-source. If you cannot distribute modifications under GPL-3.0, commercial or proprietary embedding is problematic without seeking legal review.
- You require pre-authorization scanning of external cloud infrastructure — While Vuls works well with AWS without pre-authorization per the README, integration with other cloud providers or strict access control policies may require verification.
- Real-time, zero-latency vulnerability alerting is critical — Vuls relies on periodic scans (CRON-based); it is not designed for streaming real-time threat detection or immediate anomaly response.
License & commercial use
GPL-3.0 (GNU General Public License v3.0). Copyleft license: derivative works and modifications must be distributed under GPL-3.0, with source code made available.
Commercial use of unmodified Vuls is permissible under GPL-3.0. However, if you modify, embed, or integrate Vuls into proprietary products, you must distribute the modified source under GPL-3.0. Internal business use of unmodified software is allowed. Requires legal review before embedding in closed-source systems or SaaS offerings.

Vuls is a scanning and detection tool, not a defense mechanism. No exploit execution or active remediation. Considers: (1) Scanner identity and SSH keys require protection; (2) Scan results contain sensitive asset inventory and vulnerability data—protect output and logs; (3) Agent-less scanning reduces attack surface on targets compared to agent-based alternatives; (4) Offline mode isolates scanner from internet in air-gapped networks; (5) No security audit or formal security testing data provided in README. Requests for vulnerability disclosures or security posture should be directed to project maintainers.
Alternatives to consider
OpenVAS
Full-featured vulnerability assessment platform with active scanning, agent-based and agent-less modes, and authenticated/unauthenticated scans. Heavier resource footprint; different license (AGPL-3.0 core, some modules proprietary). Better for comprehensive IT asset discovery.
Trivy (Aqua Security)
Lightweight, container-focused vulnerability scanner (Apache 2.0 license) that excels at scanning container images, filesystems, and application dependencies. Simpler CI/CD integration, broader OS/arch support. Less suitable for OS-level system scanning at scale.
Qualys VMDR / Rapid7 Nexpose
Cloud-managed SaaS vulnerability management platforms with real-time threat intelligence, automated remediation workflows, and compliance reporting. Proprietary, recurring cost, but eliminate local infrastructure and database management overhead.
