Parrot OS

What is Parrot OS?

Parrot OS (Parrot Security) is a free, open-source Debian-based GNU/Linux distribution built for offensive security, forensics, privacy and development. It is the main alternative to Kali Linux: it ships hundreds of preinstalled pentesting tools but with a lighter footprint and a design that also suits daily use. In fact, Hack The Box's Pwnbox (the in-browser attack machine) is based on Parrot.

Available editions

• Security Edition: the full version with pentesting, forensics, reverse engineering and cryptography tools.
• Home Edition: the same base without the hacking arsenal, aimed at privacy and everyday use.
• Hack The Box Edition: customized for people practicing on HTB.
• Raspberry Pi, cloud and Docker images, useful for lightweight labs.

What it is used for

• Pentesting and CTFs: Nmap, Metasploit, Burp Suite, sqlmap, Hydra, John the Ripper and many more come ready to use.
• Privacy: includes AnonSurf to route traffic through Tor, plus sandboxed apps with Firejail.
• Forensics and reverse engineering: tools such as Binwalk or Ghidra are available in the repositories.
• Low-spec machines: the default MATE desktop uses fewer resources than other environments.

How to install Parrot OS

1. Download the ISO from the official site parrotsec.org and verify its hash.
2. Recommended for beginners: use the OVA image or import the ISO into VirtualBox or VMware. That gives you snapshots and keeps your main system untouched.
3. If you prefer a bare-metal install, write the ISO to a USB drive with balenaEtcher or Ventoy and boot from it.
4. After installing, update the system before anything else.

# Verify the downloaded image
sha256sum Parrot-security-*.iso

# Update the system (Parrot's recommended method)
sudo parrot-upgrade

# Standard Debian alternative
sudo apt update && sudo apt full-upgrade

Practical examples

Anonymize traffic with AnonSurf (routes the whole system through Tor):

sudo anonsurf start
anonsurf status
sudo anonsurf changeid
sudo anonsurf stop

Use Parrot without installing it, via its Docker images:

docker run --rm -ti --network host parrotsec/security

First reconnaissance in a lab (for example, connected via VPN to TryHackMe):

nmap -sC -sV -oN scan.txt 10.10.10.10
whatweb http://10.10.10.10

Remember: use offensive tools only on your own systems or with authorization.

Pro tips

• Work in a virtual machine and take snapshots before big changes; recovering a broken system takes seconds.
• Do not run everything as root: Parrot uses a regular user plus sudo by design; keep it that way.
• AnonSurf is not foolproof: Tor hides your IP, but your behavior, accounts and browser can still identify you.
• Install only what you use on the Home Edition and add tools with sudo apt install as needed.

Pros and cons

• Pros: free and open source, lighter than many alternatives, privacy focus, usable as a daily driver, good Hack The Box integration.
• Cons: smaller community and documentation than Kali, some tutorials assume Kali and require adapting paths or packages, and major upgrades can occasionally break heavily customized installs.

Parrot OS vs Kali Linux

Both are Debian-based and share most tools. Kali has more documentation and is the standard in courses like OffSec's; Parrot is lighter and includes more privacy utilities. For learning, either works: what matters is mastering the tools, not the distribution.

Alternatives and related resources

• Surfshark: commercial VPN to protect your connection on public networks.
• Hack The Box: its Pwnbox runs Parrot and is ideal for practicing with it.
• TryHackMe: guided rooms to learn the tools Parrot ships with.

Frequently asked questions

Is Parrot OS free?

Yes. It is free and open-source software; you can download, use and modify it at no cost.

Is it legal to use Parrot OS?

Yes. Using the distribution and its tools is legal; attacking systems without authorization is not.

Parrot OS or Kali for beginners?

Both work. If your machine is modest or you want a daily-driver system, Parrot is a good choice; if you are following a Kali-based course, use Kali so you do not have to adapt anything.

Can I use Parrot OS as my main system?

Yes, especially the Home Edition. The Security Edition is more comfortable inside a virtual machine.
