Gamified Secure Coding CTF for Teams

You’re Catching Vulnerabilities Too Late

You’re still finding security bugs in production. Every time, it costs you time, money, and reputation. You bought the tools. You did the training. But vulnerabilities still get through. Why? Because your developers don’t think like attackers.

They aren’t seeing how their code can be exploited, so they keep making the same mistakes. And you’re stuck reacting: patching late, firefighting, explaining to the board why it happened again. And it’s all because your teams can’t spot what attackers see.

Your Security Problems Are People Problems

Catch security bugs before they reach production

Developers will spot and fix vulnerabilities while they build, not after release day. Fewer bugs escape, fewer headaches later.

Stop wasting time on last-minute fixes

When security issues get caught early, teams stay focused on real work instead of scrambling to patch bad code under pressure.

Keep up with attackers

Proactive teams build stronger defenses. Instead of reacting to the latest breach, they already know how to block it.

Lead a team that builds secure code by default

Skilled developers don’t need constant reminders, instead, they see the risks, fix them fast, and write safer code as part of the job.

Feel confident your team can handle real attacks

You’ll know your developers have seen how real attacks work. That peace of mind means fewer surprises and more trust in your team’s skills.

Stop stressing over security gaps you can’t see

With AppSecFlag, you’ll see your team’s progress clearly. You’ll know where you stand and see real improvement, not just hope for the best.

Not Just Another Training Tool

Most CTFs are built for red teams. This one trains the people who build and defend real apps.

Fix, Not Just Find

Developers don’t stop at spotting the bug. They also fix it and learn how to prevent it next time. The focus stays on writing secure code instead of just winning points.

Built for Defenders

Most CTFs are made for red teams. AppSecFlag trains the people who build and ship software so they can stop real attacks in real code.

Build Custom Challenges in Seconds

There’s no need to handcraft every scenario. The system uses AI to generate new, realistic challenges in seconds and ramps up difficulty as your team improves.

Run CTFs That Fit Your Needs

Add as many challenges as you want into a single event, decide how scoring works, set time limits, and even brand the event with your own logo if you like.

Let Teams Compete or Practice on Their Own

Your people can train solo or team up and compete. Every submission is tracked, scores update live, and the leaderboard keeps everyone honest.

Offer Hints Without Giving Away the Answer

The first hint is free. After that, teams lose points when they ask for help. You control how much each hint costs. Simple way to keep it challenging.

Manage Users and Teams Without Overthinking It

Invite users with a link or add them directly. Build teams, assign them to events, and run CTFs with up to 100 people. No mess, no hassle.

Change Settings Anytime You Need

If you need to adjust points, time limits, or challenge details, you can do it on the fly even after the event starts.
