CyberStart Closed: 7 Best Alternatives for Students (2026)

What Happened to CyberStart?

CyberStart was a browser-based cybersecurity training game where players became agents of a fictional Cyber Protection Agency and solved more than 200 capture-the-flag challenges across four bases. It ran from 2014 to 2024, and its own legacy page counts more than 300,000 users and 5,500 schools.

The platform wound down in two steps. In late 2023, players were emailed a warning that "the CyberStart platform will be fully closed down in early 2024," and play access ended in January. The site's current terms page then describes "the CyberStart product, which closed down in March 2024." What remains at cyberstart.com is a memorial: a timeline, the team, and testimonials. There is no login and no way to play.

CyberStart was never just one program. It was the engine behind several national initiatives, and each of them ended with it:

What CyberStart America Offered (and What You Lost)

CyberStart America gave US high school students free access to the full game. It was run with the National Cyber Scholarship Foundation, which used the game to spot talent, then offered free SANS Institute training and scholarships to the top scorers. That is the part people miss most, and it is the hardest part to replace: the scholarship pipeline went away with the game, and the foundation's website has since expired.

The game itself is easier to replace, because it was built on standard CTF skills. Here is what each base covered:

• Intern base: 12 free starter challenges for new players.
• Headquarters: the largest base, covering code-breaking, forensics, and reverse engineering.
• Moon base: Python programming challenges built around alien signals.
• Forensics base: crime-scene style cases, with evidence to analyze.

Under the story, the topics were ordinary CTF material: cryptography, password security, steganography, file and network forensics, browser developer tools, scripting, the Linux command line, and assembly debugging. Every one of those has a free, well-maintained home today. You just have to know where to look, because no single site copies CyberStart's storyline.

The 7 Best CyberStart Alternatives in 2026

We picked these for students first. Every entry is legal, built to be attacked, and either free or cheap. Prices and dates were checked on each official site in September 2026.

1. picoCTF and the CyLab Security Academy: the closest replacement

If you only try one alternative, make it this one. picoCTF is Carnegie Mellon University's free capture-the-flag program, and like CyberStart it was built for younger players: CMU describes its annual competition as "designed for middle school, high school, and college students." The challenges cover the same ground as CyberStart's Headquarters, with cryptography, forensics, web exploitation, and reverse engineering, plus a General Skills category for absolute beginners.

One change to know about: on May 8, 2026, picoCTF.org became the CyLab Security Academy, run by the same CMU team. The new site describes itself as "Always free, and built by computer security experts at Carnegie Mellon University," and older picoCTF logins still work there. The 2026 picoCTF competition started on March 9 and ran for 10 days, according to CMU CyLab's announcement, and the practice challenges stay open all year. Our picoCTF beginner guide covers which categories to start with.

What it lacks is the story. There are no bases or agents, just challenges. If you liked CyberStart for the puzzles rather than the plot, you will not miss it.

2. CyberPatriot: best for JROTC cadets and school teams

CyberPatriot is a national youth cyber defense competition created by the Air & Space Forces Association. It is the natural next step for JROTC units that used CyberStart, because the All Service Division is for JROTC, Civil Air Patrol, and Naval Sea Cadet Corps teams, and its registration fee is waived automatically.

It is a different game, though. CyberStart was mostly offense: find the hidden flag. In CyberPatriot, teams of two to six students get virtual Windows and Linux machines and have to "find and fix cybersecurity vulnerabilities" before the clock runs out. That is closer to real system administration work. For the 2026-27 season (CyberPatriot 19), the official schedule lists $225 per team for the Open Division and $175 for Middle School. Title I schools can request a waiver, and fees are waived on request for all-girl teams. Team registration ran from June 2 to October 1, 2026, so if you missed it, plan for next season.

3. National Cyber League: the best path toward scholarships and a resume

The National Cyber League (NCL) is the closest thing left to CyberStart America's competitive side. Its Fall 2026 season has a practice Gymnasium from August 17 to December 11, an Individual Game from October 23 to 25, and a Team Game from November 6 to 8. Registration costs $45 until October 9, then $55 during late registration from October 10 to 13.

NCL is open to high school students, college students, and adults. Anyone who is not a student plays as an "Industry Player." Every player earns a Scouting Report, which NCL describes as evidence "to employers that you are job-ready." It is harder than CyberStart. Do a few weeks of picoCTF first.

4. OverTheWire Bandit: the Linux command line, level by level

CyberStart taught the Linux command line in small doses. Bandit makes it the whole game. You connect to a real server over SSH, and each level hides the password for the next one. OverTheWire says Bandit is "aimed at absolute beginners," and the levels currently run from 0 to 33. The first step is the whole tutorial:

ssh [email protected] -p 2220
# password: bandit0
bandit0@bandit:~$ ls
readme
bandit0@bandit:~$ cat readme

No account, no install beyond an SSH client. Our OverTheWire wargames guide explains which game to play after Bandit.

5. SANS Holiday Hack Challenge: the most like CyberStart's story mode

If what you loved about CyberStart was the world, the missions, and the characters, this is the one. Every year SANS opens a free online game with avatars, a storyline, and dozens of real challenges, from 10-minute beginner tasks to hard final objectives. The 2025 edition launched on November 5, 2025, and the range stays open year-round. SANS also ran the training side of CyberStart America, so the style will feel familiar.

6. TryHackMe: guided rooms, but read the limits

TryHackMe teaches through guided "rooms" with questions to answer as you go, which suits students who liked CyberStart's Field Manual. The free plan gives you free rooms only and a one-hour daily limit on its in-browser attack machine. For schools, TryHackMe's help center lists an education license at $30 per license per month with a $2,000 minimum order, which rules it out for many classrooms. Individual students can get 20% off the annual Premium plan. Check TryHackMe's pricing page before you commit, because the free tier runs out quickly once you get serious.

7. HackerDNA: a daily habit plus real labs

HackerDNA's daily hack is the closest thing to CyberStart's Intern base: one short, self-contained puzzle per day, with no Docker, no VPN, and no VM. When you want more, the challenge labs cover the same categories CyberStart did. The Caesar Shift Decoder is pure code-breaking, other labs hide flags in image files or phishing email headers, and the guided labs walk you through your first real target step by step. Everything runs in the browser, which matters on a locked-down school laptop.

CyberStart Alternatives Compared

Which CyberStart Alternative Should You Pick?

Pick by situation, not by which site looks most like the old game. Here is how we would steer a friend:

1. You are a student on your own: start picoCTF's General Skills challenges this week, and do one daily hack each morning. Two sources is plenty.
2. You loved the storyline: the SANS Holiday Hack Challenge, then picoCTF once the story runs out.
3. You are in JROTC: talk to your instructor about a CyberPatriot All Service team. The fee is waived, and teams that reach the national finals travel all-expenses paid.
4. You want something for your college application: the National Cyber League. A season's scouting report is concrete proof of skill.
5. You finished CyberStart's Headquarters before it closed: skip the beginner material. Go to picoCTF's harder challenges, then enter a real CTF competition.

One honest opinion: do not wait for a CyberStart clone. Nobody has rebuilt the agency storyline, and picoCTF's challenges teach the same skills today. The flags are the fun part anyway, and the missing story stops mattering once you start solving things.

For Teachers: Replacing CyberStart in the Classroom

CyberStart's Groups feature let teachers track progress and run class leaderboards, and that is the feature most schools now need to replace. The closest free option is the CyLab Security Academy, where, in its own words, "Teachers assign paths and challenges, track student progress, and run events scoped to their class." It costs nothing, and CMU has run the picoCTF competition for more than a decade.

In practice, a mix works better than one platform. A setup that works well in a club or class:

• Weekly: assign a CyLab Security Academy path so everyone moves through the same material.
• Daily warm-up: put one short puzzle on the board at the start of class. Ten minutes, one flag, then discuss how people solved it.
• Each fall: enter the strongest students in CyberPatriot or the National Cyber League, so they have a competition to aim for.

If your students ask what capture the flag even means, give them the plain version: find a hidden secret in a system built to be broken, submit it, get points. Our guide to entering a CTF competition explains the formats and how a first event weekend goes.

Legal and Ethical Considerations

• Stay inside the challenge: attack the challenge targets, never the platform's own servers or other players.
• Do not test your school's systems: "I was just practicing" is not a legal defense, and schools treat it as a serious disciplinary issue.
• Keep live answers private: write-ups for finished competitions are encouraged. Sharing flags during a live event gets teams disqualified.
• Check age rules: competitions set their own eligibility and consent rules for minors, so read them before you register.
