Recommended Free Tools
Kicksecure is a free, open-source Linux distribution based on Debian, with security-focused defaults and layered hardening. Its operating-system package updates use Tor by default, but that does not route all applications or internet traffic through Tor. Kicksecure is a hardened base—not a guarantee against malware or compromise.
What Kicksecure is—and what its security claims mean
Kicksecure is a reconfigured Debian system designed to make a range of security protections part of the default setup. The project describes its aim as providing “a highly secure computing environment.” That is an aspiration, not a promise that every threat is prevented.
According to the Kicksecure project overview, its documented protections include:
- Separate daily and administrative roles: the
user-sysmaint-splitdesign distinguishes a regular user account from a maintenance account. - System hardening: the
security-miscpackage applies settings for areas such as kernel security, account protections, network behavior, entropy, legacy logins, and restrictive mounts. - AppArmor: profiles restrict the actions of supported applications.
- USBGuard: a policy-based approach to controlling which USB devices are authorized.
- Reduced exposure by default: the project says Bluetooth is disabled and there are no open server ports by default.
These are features described by the project, not results of an independent security audit or a test of every possible installation. Their practical effect depends on the device, software, configuration, and threats a user faces.

What Tor does—and does not—cover
Kicksecure routes APT operating-system upgrades and software installation through Tor by default, according to its overview. This is an update-privacy feature: it does not mean that web browsers, other applications, or all machine traffic are automatically sent through Tor or anonymized.
Which Kicksecure release is current?
On the project release page reviewed for this article, Kicksecure 18 is supported and based on Debian 13 (trixie). Kicksecure 17, based on Debian 12 (bookworm), is being deprecated. The project does not publish a fixed release schedule, and support status can change; check the live release information before installing or upgrading.

Where you can install or run Kicksecure
The project documents several deployment paths, including a direct hardware installation, virtual machines, Qubes, KVM, USB installation, portable use from a USB-host setup, and converting an existing Debian system. Available images and instructions vary by platform; the download page is the current reference for images and support.
| Option | Useful when | Considerations |
|---|---|---|
| Install on hardware | You want Kicksecure as the computer’s operating system. | Check the listed architecture and follow the platform-specific installation guidance. |
| Run in a virtual machine | You want to run Kicksecure as a guest on an existing host. | VM performance depends on the host and on memory available for both systems; the project recommends additional RAM for multitasking. |
| Qubes or KVM | You are using one of these documented virtualization environments. | Use the instructions for the chosen platform rather than assuming all installation paths are interchangeable. |
| USB installation or portable USB-host setup | You need a USB-based installation or want to use a portable host configuration. | Follow the relevant USB instructions and check the download page for supported hardware and images. |
| Morph an existing Debian system | You have a compatible Debian installation and want to convert it instead of installing from an ISO. | The documented prerequisite is Debian 13 (trixie). Morphing a Debian live session is unsupported, and some defaults differ from a clean ISO installation. |
The project’s download page lists Intel/AMD64, ARM64, Raspberry Pi, ppc64el (POWER9/10), and RISCV64. It marks Apple Silicon as unsupported on the page reviewed; platform status may change, so verify the current listing before proceeding.
Choosing between an ISO install and Debian morphing
For a straightforward, documented installation, start with the ISO or the instructions for your platform. Morphing is an advanced alternative with a specific Debian 13 prerequisite; it is not equivalent to installing a clean Kicksecure image. The project’s Debian morphing documentation describes the process and its limits.
Hardware requirements and realistic expectations
Kicksecure’s requirements page points readers to Debian’s minimum hardware requirements rather than providing a complete Kicksecure-specific baseline. It lists 512 MB of RAM for running without a desktop environment and 768 MB to launch LXQt. These are project-stated configuration figures; the page does not date them or present them as independent benchmark results.
Rank #4
Launching a desktop is not the same as having enough resources for comfortable everyday work. The project recommends extra disk space for additional applications, an SSD for better performance, and more RAM for multitasking in a virtual machine. Choose resources for the applications and host/guest workload you intend to run, rather than treating the minimum figures as a recommended allocation. See the system requirements.

Do not treat an ISO download alone as proof that the file is authentic. Kicksecure recommends verifying digital signatures and documents OpenPGP verification for downloaded images; HTTPS/TLS protects the connection but is not a substitute for checking the signature. Follow the project’s current download verification instructions.

Is Kicksecure a good fit?
Kicksecure is worth considering if you want a Debian-based system with project-configured security measures and an update path that uses Tor for APT operations by default. It can be deployed on supported hardware or in documented virtualized and USB-based setups.
It may not fit if your device is unsupported, you need a turnkey guarantee against compromise, or you expect all internet traffic to use Tor automatically. Before choosing an installation route, confirm current platform and release support, then compare the required isolation, available resources, and whether you prefer a clean ISO installation or the more limited Debian morphing path.
