KP3 revealsVideo download blocking
Your students can watch your lessons. Download tools can’t touch them.

Dear friend,
If you’re looking at Video download blocking to get more customers and more revenue without taking on more work yourself, this could be the most important page you read this week.
KP3’s video server blocks download tools and the browser’s download button, hides links, encrypts with AES, and uses tokens plus an AI that spots unusual requests and cuts them off. It works on phones too, at 480p to 4K.
The dynamic watermark carries each student’s details. If a video gets out, you know who leaked it and have the evidence to file a complaint. Straight talk: the system can’t block screen recording; if you need that, see the DRM package.
But before I tell you what KP3 does, let me ask you one question…

Course just launched, videos already pirated
- You spent months filming the course.
- A week after launch, the videos are in a piracy group, selling for a few hundred thousand dong.
- New students buy the pirated copy, and you don’t know who leaked it.
If you nodded at even one line above, it’s not your fault. It’s a sign that the way you work now has run out of room to grow.
The good news: there’s a faster, surer way — and you don’t have to do it yourself.

Film your next course without worry
- Your work is protected. Invest in filming your next course with peace of mind.
- Downloads blocked, every device works. Download tools and the browser’s download button blocked; works on phones, 480p to 4K.
- Know who leaked it. A dynamic watermark per student, and evidence to back a complaint.

Wait… this service isn’t for everyone
Because KP3 commits to KPIs, we only take on businesses we’re sure we can help:
- You already have a product or service that customers really buy — KP3 helps you sell more; it doesn’t find you a product.
- You’re ready to let KP3 lead on the expertise — you review and decide, but you don’t take the work back.
- No banned goods, no pyramid schemes, no scams, and nothing you wouldn’t dare tell your mother about.

Questions you might be asking yourself
Does it block 100%?
Nobody can block 100%. The system blocks the common download tools, and the watermark helps you trace whoever leaked it.
Does it block screen recording?
No. If you need that, use the DRM package.
P.S. You could keep doing everything yourself, try a few more tools, hire a few more people — and hope next month turns out different.
Or you could spend 30 minutes talking with the KP3 team. We’ll show you exactly where you’re losing customers and how to fix it — free, no strings attached. Even if you don’t hire KP3, you leave with a growth map.
