Why does protection matter to you?

Attacks against websites are becoming more serious and frequent every day. The risk to your business and customers is hugely increased by not having login protection in place. Here’s why.

Why People Love Lemin

Muttalip Olgun
CEO, Retainable
We love that Lemin can be tailored to match our branding and design.

One of the major draws was the ability to customize Captchas. A lot of the other Captchas we tried were kind of ugly and distracted from the design of our website. The easy-to-adjust security levels are also extremely helpful.

Jan Margold
Business Owner
Before Lemin, my team was wasting so much time and budget filtering out bot accesses.

Through using Lemin, we quickly discovered that bots were generating ⅔ of access. We have since been able to cut out unnecessary resources and labor time.

Why Robots Hate Lemin

Malicious Bot
Lemin makes it impossible for me to do my job. I got detected immediately. Lemin lets their customers do risk-scoring and dynamically control security, which is great for them but sucks for me and my pals.

Dear Lemin, Please stop constantly updating your algorithms. It doesn’t give us a chance. No fair!!! It’s like you’re getting smarter every day…
