Parrot OS 7.4 vs Kali 2026.3: What’s Actually Different (Tested)

Open two terminal windows. Start Parrot in the first and Kali in the second, then refresh the package lists in both.

Terminal 1 (Parrot):

# docker run -it --name parrot parrotsec/core bash
# apt update

Terminal 2 (Kali):

# docker run -it --name kali kalilinux/kali-rolling bash
# apt update

From here on, run each command in both terminals unless the step says otherwise.

# grep -E "PRETTY|VERSION_ID|DEBIAN_VERSION" /etc/os-release

PRETTY_NAME="Parrot Security 7.4 (echo)"
VERSION_ID="7.4"
DEBIAN_VERSION_FULL=13.6

PRETTY_NAME="Kali GNU/Linux Rolling"
VERSION_ID="2026.3"

Reading it. Parrot gives a release number and tells you it is built on Debian 13.6, the current stable Debian. Kali calls itself Rolling: 2026.3 is just the name of the latest snapshot, not a fixed base. That one line is the biggest difference between the two, and the next two steps show what it means in practice.

# apt-cache policy | grep -oE "release o=[^,]+,a=[^,]+" | sort -u

release o=Parrot,a=parrot
release o=Parrot,a=parrot-backports
release o=Parrot,a=parrot-security

release o=Kali,a=kali-rolling

Reading it. Parrot pulls from three branches: the main release, a separate security branch for fixes, and backports for newer versions of selected tools. That is the Debian stable model: the base stays put and fixes arrive on top. Kali has a single kali-rolling branch: everything moves forward together, all the time. Stable means fewer surprises after an update; rolling means newer tools sooner and the occasional broken dependency after apt full-upgrade.

# apt-cache policy nmap tor | grep -E "^[a-z]|Candidate"

nmap:
  Candidate: 7.95+dfsg-3
tor:
  Candidate: 0.4.9.14-0+deb13u1

nmap:
  Candidate: 7.991+dfsg-1kali1
tor:
  Candidate: 0.4.9.14-1

Reading it. nmap is 7.95 on Parrot (the Debian 13 package) and 7.991 on Kali, which packages new releases itself (the kali1 tag). tor is the same 0.4.9.14 on both, but Parrot’s copy carries +deb13u1: a Debian security update applied to the stable version. When a write-up says “use the new flag in nmap 7.99,” this is why it works on one and not the other. Always check apt-cache policy before blaming the tutorial.

kali-linux-everything
kali-linux-firmware
kali-linux-firmware-graphics
kali-linux-headless
kali-linux-labs

kali-linux-wsl

Reading it. Parrot groups its tools by job: install only parrot-tools-forensics or parrot-tools-web. Kali groups them by size: core, default, large, everything. Neither container comes with the tools installed, which is why the images are small. Parrot now has an AI bundle (parrot-tools-ai); Kali has kali-linux-labs, a set of deliberately vulnerable practice apps meant for your own machine only.

Parrot terminal only. AnonSurf is Parrot’s “send everything through Tor” switch. Fetch the package file and list what is in it. Nothing is installed or switched on.

# cd /tmp && apt download anonsurf
# dpkg -c anonsurf_*.deb | grep -E "etc/|systemd/|bin/" | awk '{print $6}'

./etc/
./etc/anonsurf/
./etc/anonsurf/anonsurf.cfg
./etc/anonsurf/bridges.txt
./etc/anonsurf/onion.pac
./lib/systemd/
./lib/systemd/system/
./lib/systemd/system/anonsurf-identity.service
./lib/systemd/system/anonsurf-recovery.service
./lib/systemd/system/anonsurfd.service
./lib/systemd/system/tor@default.service.d/
./lib/systemd/system/tor@default.service.d/anonsurf-recovery.conf
./usr/bin/
./usr/bin/dnstool

Reading it. Lines ending in / are folders. The version is 6.0.1 (in the file name). AnonSurf 6.0, new in Parrot 7.4, runs as systemd services: one does the routing, one gets you a new Tor identity, and a recovery service puts your network settings back if the machine crashes while AnonSurf is on. A tool that needs a recovery service is a tool that changes things deep in your system, so the next step looks at what.

Parrot terminal only. Unpack the files into a folder (still not installing) and read the config.

# dpkg -x anonsurf_*.deb anonsurf
# grep -E "plain|sandbox|bridge" anonsurf/etc/anonsurf/anonsurf.cfg

use_sandbox=false
bridge_address=""
auto_bridge=false
reject_plain_port=false
list_plain_ports="23,109,110,143"

Reading it. Ports 23, 109, 110 and 143 are Telnet, POP2, POP3 and IMAP: old protocols that send passwords in plain text. Through Tor, the last computer in the chain (the exit node) is run by a stranger and can read anything unencrypted. AnonSurf warns about those ports by default but does not block them (reject_plain_port=false). Bridges are for networks that block Tor; they are off by default.

Parrot terminal only. The main program is compiled, but you can still search it for the settings it writes.

# grep -aoE "TransPort [0-9.:]+|DNSPort [0-9.:]+|disable_ipv6|iptables-restore|/run/anonsurf/active" anonsurf/usr/lib/anonsurf/anondaemon | sort -u

/run/anonsurf/active
DNSPort 127.0.0.1:53
TransPort 127.0.0.1:9040
disable_ipv6
iptables-restore

Reading it. When AnonSurf is on, it makes Tor listen on port 9040 and uses firewall rules (iptables) to force all traffic there; it answers DNS itself on 127.0.0.1 so lookups go through Tor too; it turns off IPv6 so nothing slips out around Tor; and it drops a marker file at /run/anonsurf/active. It backs up your firewall rules first and restores them when you switch it off.

What it doesn’t hide. Tor hides your IP address, not who you are: log in to an account and the site knows it’s you. The list of Tor exit addresses is public, so many sites and company firewalls block or flag them; to a SOC, traffic from a Tor exit is a signal, not invisibility. The checklist above comes from the package files; we read AnonSurf but did not run it inside a container.

For a home lab, either works, and nothing stops you running both. Type exit in each terminal, then remove the containers from your normal terminal:

# docker rm -f parrot kali

Add docker rmi parrotsec/core kalilinux/kali-rolling if you want the disk space back too.
