What Is Hack The Box? Free vs Paid + How HTB Works (2026)

What Is Hack the Box?

Hack the Box (HTB) is an online cybersecurity training platform that lets you practice hacking skills against vulnerable machines and challenges in a safe, legal environment. Founded in 2017 by Haris Pylarinos in Greece, the platform has grown into one of the largest cybersecurity communities in the world.

At its core, HTB provides virtual machines with intentional security vulnerabilities. Your job is to find and exploit those weaknesses, escalate your privileges, and capture "flags" (hidden text strings that prove you completed the challenge). This hands-on approach mirrors real-world penetration testing, which is the practice of testing computer systems for security flaws with the owner's permission.

HTB has expanded well beyond its original machine-hacking roots. The platform now includes:

• HTB Labs - Vulnerable machines and challenge categories (the original product)
• HTB Academy - Structured courses and learning paths with guided instruction
• Pro Labs - Enterprise-level network simulations for advanced users
• CTF competitions - Regular Capture the Flag events with global leaderboards
• Certifications - Practical exams like CPTS and CBBH that validate real skills

How Hack the Box Works

Getting started on HTB follows a straightforward process, though the learning curve once you are inside can be steep. Here is how the platform works step by step.

Creating Your Account

Sign up for a free account at hackthebox.com. You get immediate access to a limited selection of active machines and challenges. No credit card required for the free tier.

Starting Point: The Free Guided On-Ramp

The reputation HTB has for being brutal to beginners comes from its main machine pool. It is not the whole picture. Starting Point is a separate, guided track built for people who have never rooted a box, and free accounts get all of it (HTB documents the track in its Starting Point guide).

It runs across three tiers. Tier 0 introduces the tooling and the idea of enumeration. Tier 1 gives you six machines built around a single primary exploitation step, so the path from foothold to flag stays short enough to follow. Tier 2 machines are full-fledged: you enumerate, gain an initial foothold, and escalate privileges to reach root or SYSTEM, chaining several steps together the way a real box does.

What makes it work is the guidance. Each machine walks you through a set of logical tasks and questions that lead you to each flag, and every task carries a hint if you stall. That is the opposite of the unguided experience HTB is known for, and it is the right place to begin if the platform has intimidated you before.

Connecting to the Lab Environment

HTB machines run on private networks that you access through a VPN (Virtual Private Network) connection. You have two options:

• OpenVPN connection - Download a configuration file and connect from your own machine. This is the standard approach if you use Kali Linux or another penetration testing distribution locally.
• Pwnbox - HTB provides a browser-based Kali Linux environment called Pwnbox. It comes with common hacking tools pre-installed, so you can start immediately without any local setup. Free users get limited Pwnbox time; paid subscribers get more.

Hacking Machines and Capturing Flags

Once connected, you select a machine to attack. Each machine has at least two flags to find:

• User flag - Located in a regular user's home directory. Getting this usually requires finding an initial vulnerability and gaining access to the system.
• Root flag - Located in the root (administrator) directory. Reaching this requires privilege escalation, which means exploiting additional vulnerabilities to gain full control of the machine.

You submit these flags on the HTB website to earn points and climb the rankings. The platform tracks your progress, assigns a hacker rank, and maintains global leaderboards.

That rank is calculated from the percentage of active content you have owned, which catches most newcomers off guard. The ladder runs Noob, Script Kiddie (above 5%), Hacker (above 20%, which unlocks Fortresses), Pro Hacker (above 45%), Elite Hacker (above 70%), Guru (above 90%), and finally Omniscient at 100%, as set out in HTB's introduction to HTB Labs.

The catch: when a machine retires, the points you earned from it drop to zero. You keep the rank you reached, but holding a high rank means continuing to work through current machines rather than resting on old ones. It is a deliberate design choice, and it explains why HTB rank is treated as a signal of recent, active practice rather than a lifetime score.

Challenge Categories

Beyond full machines, HTB offers standalone challenges in categories including:

• Web exploitation
• Cryptography
• Reverse engineering
• Binary exploitation (pwn)
• Forensics
• Hardware and misc challenges

These smaller challenges help you practice specific skills without committing to a full machine walkthrough. They are a good way to sharpen individual techniques.

Everything carries a difficulty label so you can pick sensibly. Machines are rated Easy, Medium, Hard, or Insane; challenges add a Very Easy tier below those. Treat "Easy" as relative to HTB rather than to the wider world: an Easy box still expects you to enumerate properly and work without hand-holding.

The library also moves. One new machine is released every week, and one older machine retires at the same moment. That rotation is what separates active from retired content: while a machine is active there are no public write-ups for it, so you are genuinely solving it yourself. Once it retires, the write-ups and official walkthroughs appear, which is why the retired library is where most people do their structured learning.

Hack the Box Free vs Paid Tiers

Understanding what you get for free and what requires a subscription is essential before committing time to the platform. HTB recently simplified its pricing by consolidating to a single paid tier called VIP+.

The free tier gives you enough to try the platform, but the experience can be frustrating. Shared servers mean other users might reset your machine mid-hack, and you cannot access retired boxes where most of the learning content and community walkthroughs exist.

VIP+ at $25/month (or about $18.60/month billed annually at $223/year) unlocks the full library of retired machines, official walkthroughs, and a dedicated server. For serious learners, the annual plan is the better deal.

Hack the Box Certifications: A Quick Orientation

HTB also runs a lineup of practical certifications. Unlike traditional multiple-choice exams, they test whether you can actually compromise real systems and then write the whole thing up as a professional report. The best known is CPTS (Certified Penetration Testing Specialist): a full penetration test against a multi-host network, followed by a written report. The rest of the lineup covers web exploitation, blue-team analysis, Active Directory, and wireless.

One thing catches people out here. The certifications are delivered through HTB Academy, not HTB Labs, so they sit behind a different subscription than the machines described on this page. Exam fees, voucher bundles, and the preparation paths change often enough that we keep the numbers in a single place instead of letting two pages drift apart: see our full breakdown of HTB Academy certifications and costs, which covers CPTS in depth, how the exams are structured, and which certification is worth pursuing.

Who Is Hack the Box Best For?

HTB is not a one-size-fits-all platform. Its difficulty level and approach suit certain learners better than others. Here is an honest breakdown of who benefits most.

HTB Is a Great Fit If You:

• Already know basic Linux, networking, and command-line fundamentals
• Enjoy figuring things out independently with minimal hand-holding
• Want to pursue HTB-specific certifications (CPTS, CWES, CDSA)
• Are preparing for a career in penetration testing or red teaming
• Thrive on competitive challenges and leaderboard rankings

HTB Might Not Be Ideal If You:

• Are a complete beginner with no technical background
• Need step-by-step guided instruction to build confidence
• Want courses and hands-on labs in a single subscription
• Prefer predictable, straightforward pricing
• Get frustrated easily when stuck without hints or direction

The biggest criticism of HTB from beginners is the steep learning curve. The platform's original machines offer minimal guidance, and the free tier limits your options significantly. If you are brand new to cybersecurity, starting with a more structured platform can build the foundations you need before tackling HTB's tougher challenges.

Where Hack the Box Fits Against Other Platforms

HTB sits at the harder, least-guided end of the market. It hands you a target and almost no direction, which is exactly what you want once you have the fundamentals, and quietly demoralising before you do. Platforms built around guided paths walk you through the material first; a formal course like OffSec's PEN-200 wraps its labs in structured training at a far higher price.

Rather than repeat a shallow comparison table here, we keep those side-by-sides where they get the space they deserve. Our full comparison of Hack The Box alternatives goes through pricing, features, and difficulty across every serious option.

A common path for many successful security professionals: start with structured, guided learning to build fundamentals, then move to HTB once you have the core skills to learn independently from unguided challenges.

How to Get Started with Cybersecurity Labs

Whether you choose HTB or another platform, getting the most out of cybersecurity labs requires the right approach. Here is a practical roadmap.

Step 1: Build Your Foundations

Before touching any vulnerable machine, make sure you understand the basics. You need working knowledge of:

• Linux command line (navigating directories, file permissions, basic scripting)
• Networking fundamentals (TCP/IP, DNS, HTTP, common ports)
• Web technologies (HTML, JavaScript basics, how web applications work)

A structured ethical hacking course covers all of these foundations with hands-on exercises. This kind of guided instruction helps you build confidence before moving to unguided challenges.

Step 2: Set Up Your Environment

You need a penetration testing environment. The most common options:

• Kali Linux in a virtual machine - The industry standard. Install VirtualBox or VMware, then run Kali as a guest OS. All common hacking tools come pre-installed.
• Browser-based environments - Platforms like HTB (Pwnbox) and HackerDNA Labs provide cloud-based environments so you can practice from any browser without local setup.

Step 3: Start with Easy Machines

On HTB, machines are rated by difficulty. Start with "Easy" rated boxes and follow community walkthroughs for retired machines (VIP+ required). A good Hack the Box walkthrough will teach you methodology, not just the solution. Pay attention to the enumeration process, how the author identified the vulnerability, and why specific tools were chosen.

Step 4: Build a Methodology

Successful hackers follow a consistent methodology rather than trying random exploits. A basic penetration testing workflow:

1. Reconnaissance - Scan the target to discover open ports and services
2. Enumeration - Gather detailed information about discovered services
3. Exploitation - Use discovered vulnerabilities to gain initial access
4. Privilege escalation - Elevate your access from regular user to root
5. Documentation - Record your findings and write a report

Learning network penetration testing through a structured course helps you internalize this methodology before applying it on platforms like HTB.

Step 5: Document Everything

Keep detailed notes on every machine you attempt. Record what worked, what failed, and what you learned. This habit builds the documentation skills that employers value in professional penetration testers, and it creates a personal reference library you will use throughout your career.

Frequently Asked Questions

Is Hack the Box free?

Yes, HTB offers a free tier that includes access to a limited selection of active machines and challenges. However, the free experience is restricted: you cannot access retired machines (which have community walkthroughs available), you share VPN servers with other users, and Pwnbox time is limited. The VIP+ subscription at $25/month or $223/year unlocks the full platform. HTB Academy also has free introductory modules, but most courses require a separate paid subscription.

Is Hack the Box good for beginners?

HTB Labs is generally not beginner-friendly. The machines offer minimal guidance, and even "Easy" rated boxes assume you already know Linux, networking, and basic security concepts. If you are a complete beginner, you will likely find HTB frustrating without prior preparation. A better approach is to start with a guided cybersecurity course that teaches fundamentals, then move to HTB once you can handle unguided challenges. HTB Academy is more structured but requires a separate subscription.

What certifications does Hack the Box offer?

Seven, all delivered through HTB Academy rather than HTB Labs, and all fully practical: you compromise real systems and submit a professional report instead of answering multiple-choice questions. CPTS is the flagship penetration testing credential, with the others covering web exploitation, defensive analysis, Active Directory, and wireless. Current exam fees and the preparation path for each are in our HTB Academy guide.

How do I connect to Hack the Box machines?

You connect to HTB machines through a VPN tunnel. After creating an account, download the OpenVPN configuration file from the HTB website and connect using an OpenVPN client on your machine (Kali Linux has one built in). Alternatively, use Pwnbox, HTB's browser-based Kali Linux environment that connects automatically. Once the VPN is active, you can reach the target machines on the private HTB network and start scanning, enumerating, and exploiting them.
