NetGuard
A simple way to block access to the internet per app
NetGuard is an open-source Android firewall app that lets users control internet access on a per-app basis without requiring root access, making it a straightforward and flexible way to improve privacy and data usage management on mobile devices. By creating a local VPN service on the device, NetGuard intercepts and selectively blocks or allows network traffic for individual applications and addresses, supporting both Wi-Fi and mobile connections according to user preferences. This means you can block internet access for specific apps to save bandwidth, extend battery life, or prevent unwanted background connections while still letting other apps communicate normally. NetGuard’s interface is simple, with toggles to allow or deny access and optional settings for screen-on behavior, roaming, system apps, and notification of internet usage, giving users fine-grained control over network behavior. -

Zeek
Zeek is a powerful network analysis framework
Zeek has a long history in the open source and digital security worlds. Vern Paxson began developing the project in the 1990s under the name “Bro” as a means to understand what was happening on his university and national laboratory networks. Vern and the project’s leadership team renamed Bro to Zeek in late 2018 to celebrate its expansion and continued development. Zeek is not an active security device, like a firewall or intrusion prevention system. Rather, Zeek sits on a “sensor,” a hardware, software, virtual, or cloud platform that quietly and unobtrusively observes network traffic. Zeek interprets what it sees and creates compact, high-fidelity transaction logs, file content, and fully customized output, suitable for manual review on disk or in a more analyst-friendly tool like a security and information event management (SIEM) system. -

fping
High performance ping tool
fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts. fping has a very long history: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool for network diagnostics and statistics. There was no official fping release from 2002 until end of 2011. Various patches existed, but were never integrated "upstream". Also, the official maintainer didn't answer emails, so I decided to just step up and take over maintenanceship.To mark this change of maintenance, and avoid confusion, I decided to call it version 3. Besides a new maintainer, fping now also features a completely rewritten main loop implementation which improves performance significantly. The run time is now close to the theoretical time required to send and receive the pings under the specified parameters. -

CrowdSec
Firewall able to analyze visitor behavior & provide adapted response
CrowdSec - an open-source massively multiplayer firewall able to analyze visitor behavior & provide an adapted response to all kinds of attacks. It also leverages the crowd power to generate a global IP reputation database to protect the user network. Crowdsec shouldn't, and didn't crash any production so far we know, but some features might be missing or undergo evolutions. IP Blocklists are limited to very-safe-to-ban IPs only (~5% of the global database so far, will grow soon). A modern behavior detection system, written in Go. It stacks on Fail2ban's philosophy, but uses Grok patterns & YAML grammar to analyse logs, a modern decoupled approach (detect here, remedy there) for Cloud/Containers/VM based infrastructures. Once detected you can remedy threats with various bouncers (block, 403, Captchas, etc.) and blocked IPs are shared among all users to further improve their security. Crowdsec is an open-source, lightweight software, detecting peers with aggressive behaviors. -

OpenSnitch
OpenSnitch is a GNU/Linux port of the Little Snitch firewall
OpenSnitch is a GNU/Linux port of the Little Snitch firewall. You can launch the GUI from the icon or from the system menu. The daemon will start intercepting connections, prompting you to allow or deny them. If you don't apply an action, after 15 seconds (configurable) it'll apply the default action configured. When you open the GUI, you'll see all the connections and processes that the daemon has intercepted. Double click on a row to view the details of a process, rule, host or user. Once you know which are the common processes, IPs and hosts that your machine is connecting to, you can start creating permanent rules (Duration: always) to deny or allow them. You can also convert temporary rules to permanent by right-clicking on a temporary rule or by double-clicking on it, and then edit it. By default OpenSnitch UI listens on a local Unix socket in /tmp/osui.sock. -
