grype
A vulnerability scanner for container images and filesystems
A vulnerability scanner for container images and filesystems. Easily install the binary to try it out. Works with Syft, the powerful SBOM (software bill of materials) tool for container images and filesystems. Scan the contents of a container image or filesystem to find known vulnerabilities. Find vulnerabilities for major operating system packages. Find vulnerabilities for language-specific packages. You can also choose another destination directory and release version for the installation. The destination directory doesn't need to be /usr/local/bin, it just needs to be a location found in the user's PATH and writable by the user that's installing Grype. If you're using GitHub Actions, you can simply use our Grype-based action to run vulnerability scans on your code or container images during your CI workflows. -

tfsec
Security scanner for your Terraform code
tfsec is a static analysis security scanner for your Terraform code. Designed to run locally and in your CI pipelines, developer-friendly output and fully documented checks mean detection and remediation can take place as quickly and efficiently as possible. tfsec takes a developer-first approach to scanning your Terraform templates; using static analysis and deep integration with the official HCL parser it ensures that security issues can be detected before your infrastructure changes take effect. Checks for misconfigurations across all major (and some minor) cloud providers. Applies (and embellishes) user-defined Rego policies. Supports multiple output formats: CLI, JSON, SARIF, CSV, CheckStyle, and JUnit. Configurable (via CLI flags and/or config file). Very fast, capable of quickly scanning huge repositories. Plugins for popular IDEs available (JetBrains, VSCode and Vim). -

garak
The LLM vulnerability scanner
garak checks if an LLM can be made to fail in a way we don't want. garak probes for hallucination, data leakage, prompt injection, misinformation, toxicity generation, jailbreaks, and many other weaknesses. garak's a free tool, we love developing it and are always interested in adding functionality to support applications. garak is a command-line tool, it's developed in Linux and OSX. Just grab it from PyPI and you should be good to go. The standard pip version of garak is updated periodically. garak has its own dependencies, you can to install garak in its own Conda environment. garak needs to know what model to scan, and by default, it'll try all the probes it knows on that model, using the vulnerability detectors recommended by each probe. For each probe loaded, garak will print a progress bar as it generates. Once the generation is complete, a row evaluating the probe's results on each detector is given. -

Flan Scan
A pretty sweet vulnerability scanner
Flan Scan is a lightweight open-source network vulnerability scanner designed to make it easy to detect exposed services, open ports, and associated vulnerabilities across IP ranges or network segments as part of security audit and compliance workflows. It is essentially a thin wrapper around the widely-used Nmap scanner, augmenting it with scripts and tooling that transform raw Nmap output into vulnerability-focused reports that map detected services to known CVEs, making results more actionable for administrators and auditors. Flan Scan supports automated builds via Docker and can be deployed in containers or Kubernetes clusters, allowing organizations to run scans consistently across distributed environments. Users provide target IPs or CIDR ranges, and the tool orchestrates Nmap scans with version detection and the “vulners” NSE script, collects results, and outputs aggregated reports in formats like LaTeX, markdown, or JSON. -

Vuls
Agentless vulnerability scanner for Linux/FreeBSD
Vuls is open-source, agent-less vulnerability scanner based on information from NVD, OVAL, etc. Vuls uses multiple vulnerability databases NVD, JVN, OVAL, RHSA/ALAS/ELSA/FreeBSD-SA and Changelog. Vuls v0.5.0 now possible to detect vulnerabilities that patches have not been published from distributors. Remote scan mode is required to only setup one machine that is connected to other scan target servers via SSH. If you don't want the central Vuls server to connect to each server by SSH, you can use Vuls in the Local Scan mode. Fast scan mode scans without root privilege, no internet access, almost no load on the scan target server. Deep scan mode scans in more detail. It is possible to acquire the state of the server executing some commands. Vuls v0.5.0 warns not-restarting-processes which updated before but not restarting yet. And detect processes affecting software update in advance. -

Brakeman
A static analysis security vulnerability scanner for Ruby on Rails app
Brakeman is a free vulnerability scanner specifically designed for Ruby on Rails applications. It statically analyzes Rails application code to find security issues at any stage of development. Brakeman now uses the parallel gem to read and parse files in parallel. By default, parallel will split the reading/parsing into a number of separate processes based on number of CPUs. In testing, this has dramatically improved speed for large code bases, around 35% reduction in overall scan time. Brakeman will now track and return very simple literal values (e.g. strings, hashes of literals, arrays of literals) from very simple class methods (e.g. single line). Since ActiveRecord enums essentially generate some class (and instance) methods that return fixed literal values, the above class method return values is also used to support enum. -

Cake Fuzzer
Security testing tool for CakePHP based web applications
Cake Fuzzer is an open-source project meant to help automatically and continuously discover vulnerabilities in web applications created based on specific frameworks with very limited false positives. Currently, it is implemented to support the Cake PHP framework. Cake Fuzzer is based on the concept of Interactive Application Security Testing (IAST). The goals of the project are: - create an automated process of discovering vulnerabilities in applications based on the CakePHP Framework; - no application knowledge requirement or pre-configuration of the web application; - result with minimal or close to 0 amount of false positives; - require minimal security knowledge to run the scanner. -
