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 Unfortunately, many tools and scripts are outdated or lack high-quality documentation.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. MISP (Malware Information Sharing Platform)
fraud detection, information gathering, threat hunting
MISP collects, stores, and distributes security indicators and discovered threats. This makes the platform useful for those involved with security incidents and malware research. Users benefit from having a well-tested platform to structure the vast number of data points available when it comes to security threats. The tooling allows interaction with other tools, like security incident and event management (SIEM) and intrusion detection systems (IDS).
2. 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.
3. ClamAV (malware scanner)
malware analysis, malware detection, malware scanning
ClamAV is a popular tool to detect malicious software or malware. While it calls itself an antivirus engine, it probably won't encounter many viruses, as they have become rare. It is more likely to find other forms of malware like worms, backdoors, and ransomware. ClamAV can be used in a few ways, from doing an occasional scan up to scanning in batch. ClamAV does not do on-access scanning but can be combined with other tools to obtain similar functionality. ClamAV is often u…
4. 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.
5. Buttercup for desktop (cross-platform password manager)
password management
The typical users have at least a multitude of ten when it comes to passwords. Ensuring that every website has a unique password and remembering, is almost impossible. Passwords managers like Buttercup help with the generation and secure storage of these secrets. It is freely available and open source, making it a good alternative for commercial options.
6. 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.
7. osquery (operating system query tool)
compliance testing, information gathering, security monitoring
The osquery tool allows querying your Linux, Windows, and macOS infrastructure. It can help with intrusion detection, infrastructure reliability, or compliance.
8. 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.
9. 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.
10. 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.
