Useful software. Clear choices. A better way to find what you need.
OpenSnitch is an interactive Linux application firewall that observes outbound connection attempts, prompts for decisions, and applies rules by application or destination, helping users understand and control which programs communicate over the network.
LuLu is a macOS outbound firewall that alerts users to unknown network connections and applies allow or block rules, helping people inspect application traffic and decide which programs should be permitted to communicate externally.
WireGuard provides encrypted network tunnels using public-key identities and compact configuration, enabling administrators to connect devices or networks through a VPN protocol that is integrated into Linux and available through clients on other platforms.
ClamAV is an open-source malware-scanning engine with command-line and daemon interfaces, signature updates, and archive inspection, commonly used to check files or integrate scanning into mail, storage, and upload-processing systems.
Wazuh is a security monitoring platform that collects endpoint events, checks configurations, detects file changes, and correlates security information, giving teams a centralized view of systems through agents, analysis services, and dashboards.
Suricata is a network threat-detection engine that inspects traffic, applies detection rules, and records protocol events, supporting intrusion detection, prevention, and network security monitoring when deployed where relevant packets can be observed.
Zeek is a network-analysis framework that turns observed traffic into structured logs and events, with a scripting language for custom analysis, helping defenders investigate activity and build detections from protocol-level context across their networks.
ZAP is a web-application security testing tool that intercepts HTTP traffic, analyzes responses, and runs automated scanning workflows, helping developers and testers investigate weaknesses in applications they are authorized to assess during development.
Trivy scans software artifacts and configuration for known vulnerabilities, exposed secrets, and misconfigurations, supporting container images, repositories, and Kubernetes-related workflows while producing reports and software bills of materials for development and security teams.
QEMU is a machine emulator and virtualizer that can run guest operating systems and software for different processor architectures, with hardware-acceleration options and command-line controls for developers, testers, and virtualization systems.
VirtualBox is a desktop virtualization application that runs guest operating systems in virtual machines, with configurable hardware, snapshots, networking, and management tools for testing applications or maintaining separate environments on one physical computer.
virt-manager is a graphical desktop interface for libvirt virtualization that creates and manages virtual machines, adjusts virtual hardware, and displays resource use, primarily serving Linux users operating KVM and related virtualization backends.
GNOME Boxes simplifies desktop virtualization with guided operating-system installation, resource controls, snapshots, and device sharing, helping Linux users try another operating system without managing the full complexity of a server virtualization platform.
UTM is a virtualization and emulation application for Apple platforms that wraps virtual-machine configuration in a graphical interface, letting Mac users run compatible operating systems or emulate older hardware without managing raw QEMU commands.
Rufus is a Windows utility for creating bootable USB drives from operating-system images, formatting devices, and selecting compatible boot settings, helping users prepare installation or recovery media for computers they need to set up.
Ventoy prepares a USB drive with a boot menu that can load multiple image files, allowing users to copy supported ISO and other images onto the device and choose between installation or recovery environments at startup.
balenaEtcher writes operating-system images to USB drives and SD cards through a guided desktop interface, then validates the result, making it useful for preparing boot media for single-board computers and other supported devices.
GParted is a graphical partition editor for creating, resizing, moving, checking, and copying disk partitions, with a bootable live environment available for working on storage that cannot be changed while its operating system is running.
