What Our Customers Say

"We deployed NK-CAPTCHA and found out our CTO had been a DPRK agent for 3 years. Turns out he couldn't type the phrase without crying. 10/10 would recommend."

Definitely Real Person VP of Not Getting Hacked, Fortune 500

"Our interviewing process used to be 5 rounds. Now it's 5 rounds plus one CAPTCHA. The CAPTCHA is more effective than all 5 rounds combined."

Enterprise-Grade Protection

Three verification methods. Zero tolerance for regime loyalty.

🎰

Wheel of Truth

Spin the wheel to complete "Kim Jong-un is..." Three answers let you through. One gets you flagged. 75% odds sound good until your loyalty kicks in.

Mode C

Our system delivers a real-time assessment. Green = not a spy. Red = probably a spy. Orange = might just be really nervous.

Frequently Asked Questions

Is this legally compliant?

We asked our lawyer and they just stared at us for 45 seconds before leaving the room. We're taking that as a yes.

What if the candidate is just nervous?

Our Hesitation Analysis Engine™ can distinguish between "nervous about a job interview" and "nervous about committing treason against the Supreme Leader." Probably.

Can this be bypassed with a VPN?

A VPN can hide your IP address, but it cannot hide the guilt in your heart when you insult the Eternal President of the Republic.

Is the portrait folding GDPR compliant?

The Supreme Leader's portrait is not considered personal data under GDPR because he transcends mere personhood. At least, that's what he told us.

What happens if I fail the CAPTCHA?

Your name is added to a list. Which list? Let's just say you probably don't want to find out. (It's a mailing list. For coupons.)

Do you actually detect North Korean spies?

This is an April Fools' joke. Please do not use this as your actual security strategy. Although honestly, it might work better than some things we've seen.

OK, BUT SERIOUSLY

The joke is funny.
The threat isn't.

DPRK IT workers are already inside companies. They use VPNs, stolen identities, and AI agents to get through hiring. A CAPTCHA won't catch them. Knowing they're on a VPN running an AI agent will.
