Security tools
Introduction
When it comes to security tooling for Linux and other platforms, there is enough to choose from. Unfortunately, many tools and scripts are outdated or lack high-quality documentation. We are volunteering to index and categorize all security tools with an open source license.
Top 100
The database currently consists of 521 security tools. Looking for new tools? The top 100 tools is a great start.

Top 10 tools
Every week the list of tools is ranked. This is the current top 10 of tools, based on manual reviews and automatic project health measurements.
1. Faraday (collaboration tool for penetration testing)
collaboration, penetration testing, security assessment, vulnerability scanning
Faraday helps teams to collaborate when working on penetration tests or vulnerability management. It stores related security information in one place, which can be easily tracked and tested by other colleagues.
2. Brakeman (static code analyzer for Ruby on Rails)
code analysis
Brakeman is a static code analysis tool for Ruby on Rails to perform a security review. It comes as an open source project with optional commercial support.
3. Frida (reverse engineering tool)
black-box testing, reverse engineering
Frida allows developers and researchers to inject custom scripts into black box processes. This way it can provide a hook into any function, allowing to trace executed instructions. The source code is not needed. Frida even allows direct manipulation and see the results. The tool comes with bindings for different programming languages, allowing to interact with processes. Example of the bindings that Frida provides include Python, Swift, .NET, Qt/Qml, and C API.
4. Vuls (agentless vulnerability scanner)
system hardening, vulnerability scanning
Vuls is a vulnerability scanner for Linux and FreeBSD. It is written in Go, agentless, and can use a remote login to find any software vulnerabilities. It has multiple levels of scanning, from a fast scan up to a deep scan with extensive analysis.
5. Zeek (network security monitoring tool)
security monitoring
Zeek helps to perform security monitoring by looking into the network's activity. It can find suspicious data streams. Based on the data, it alert, react, and integrate with other tools.
6. mitmproxy (TLS/SSL traffic interception)
network analysis, penetration testing, security assessment
The mitmproxy tool allows to intercept, inspect, modify, and replay traffic flows. It may be used for pentesting, troubleshooting, or learning about SSL/TLS.
7. Suricata (network IDS, IPS and monitoring)
information gathering, intrusion detection, network analysis, threat discovery
Suricata can be used as part of a Network Security Monitoring (NSM) ecosystem. You could use it to log HTTP requests, log and store TLS certificates, extract files from flows and store them to disk.
8. Lynis (security scanner and compliance auditing tool)
IT audit, penetration testing, security assessment, system hardening, vulnerability scanning
Lynis can detect vulnerabilities and configuration flaws. Where a typical vulnerability scanner will just point out vulnerabilities, Lynis aims for an in-depth audit and continuous improvement. For this reason, it needs to be executed on the host system itself. By seeing the system from the inside out, it can provide more specific details than the average vulnerability scanner.
9. IVRE (reconnaissance for network traffic)
digital forensics, information gathering, intrusion detection, network analysis
IVRE is a framework to perform reconnaissance for network traffic. It leverages other tools to pull in the data and show it in the web interface.
10. Cryptomator (client-side encryption for cloud services)
data encryption
Cryptomator is a multi-platform tool for transparent client-side encryption of your files. It is used together with cloud services to ensure you are the only one who can access the data.
