If you use MacOS and you would like the functionality of Little Snitch but don’t want to pay for it, this might be an alternative to consider. I haven’t tested it, nor have I done a feature comparison between LuLu and Little Snitch, so this is just to note that it exists and nothing more.
In today’s connected world, it is rare to find an application or piece of malware that doesn’t communicate with a remote server.
LuLu is the free, open-source firewall that aims to block unknown outgoing connections, protecting your privacy and your Mac!

OpenVPN is a service to host your own VPN server, without using third-party servers.
A VPN is a secured connection between two networks, for example between your phone and your home.
In this tutorial, I’ll give you a step-by-step method to install it quickly on Raspberry Pi.

This post includes SCP examples. SCP or secure copy allows secure transferring of files between a local host and a remote host or between two remote hosts. It uses the same authentication and security as the Secure Shell (SSH) protocol from which it is based. SCP is loved for it’s simplicity, security and pre-installed availability.

We’ve used Etcher several times, mostly to make a bootable SD card for a Raspberry Pi or to put a bootable image of a Linux distribution onto a USB thumb drive. But we’re rethinking that now because we’ve read some concerns about privacy when using Etcher, or balenaEtcher as it is now called. … All we wanted to point out is that if you do have any concerns about using Etcher or balenaEtcher, there are alternatives, depending on which operating system you are using:
Introduction The scp command is used to copy files and directories between one computer to another. What is valuable about this utility is the fact that it used ssh to tunnel the copying. This means that the data is encrypted because it rides on ssh’s secure features.

A VPN (Virtual Private Network) protects your privacy by routing all your Internet traffic through an encrypted server that your ISP (or hackers) can’t see. Setting up and using a log-free VPN service from your PC desktop is straightforward enough, but other devices in your home such as your game console and set-top box don’t let you install VPN software.
One solution is to buy a router that can connect directly to a VPN service, protecting all the traffic on your home network a single stroke. But it could be cheaper (and simpler) just to route all your traffic through a Raspberry Pi that remains connected to the VPN at all times.

Here are two pages to visit to safeguard your privacy when using Firefox. Please BE CAREFUL when making changes such as these; you probably do not want to make every single change shown because if you do, you may experience unintended consequences, and may possibly even “break” certain web sites:
1. Firefox Privacy – The Complete How-To Guide
Mozilla Firefox is arguably the best browser available that combines strong privacy protection features, good security, active development, and regular updates. The newest version of Firefox is fast, light-weight, and packed full of great settings to protect your privacy.
It is for this reason that I consider Firefox to be the best all-around browser for privacy and security. It remains a solid alternative to some of the other options, such as Google Chrome, Microsoft Edge, and Safari.
Another great aspect of Firefox is that it is highly customizable, which is the point of this guide. Below we will go over how you can customize Firefox to give you the security and privacy you desire, while still working well for day-to-day browsing.
