Why form security matters 

You should take the security of web forms seriously as it involves users’ information. Users sometimes provide sensitive information or upload data through the online forms on your website. On the other side of the coin, hackers and spammers use your forms to find flaws in your website and make it behave improperly. They can use it as a mail server to send spam emails. Also, you certainly don’t want to get up one fine morning and see that your form submissions are filled with loads of spam entries. 

Hackers do more than just make your website and brand look unprofessional and submit spam entries. They can also damage your Google rankings, make your site less useful and even get you in trouble with the law. These are only some reasons why you should take the security of web forms seriously. 

What is hCaptcha? 

hCaptcha is a free-of-cost security solution that protects your site against spam while still allowing human visitors to browse the content. This bot detection tool protects your forms from spam submissions and lets you prevent automated program submissions while still maintaining a user-friendly form experience for your users. 


Before submitting the form, hCaptcha requires users to answer or resolve one or multiple challenges. The user can submit the form if the answer is correct. All of the popular modern web browsers, including Mozilla Firefox, Google Chrome, Microsoft Edge, and Apple Safari support hCaptcha. 

hCaptcha vs reCAPTCHA 

Now you might be wondering how hCaptcha compares with Google’s reCAPTCHA. The way that reCAPTCHA and hCaptcha work is the same. hCaptcha also blocks bots and spam, but unlike reCAPTCHA, it allows you more flexibility over the amount of difficulty you want to set for your website and better protects your users’ privacy. 

hCaptcha vs reCAPTCHA

hCaptcha is a relatively new tool that helps spam prevention compared to reCAPTCHA. So it has got some advantages over reCAPTCHA. Google is a much bigger company than the one behind hCaptcha. This means that spammers have less reason to program their bots to get around it. It’s not worth it yet because not enough sites use it. This could change in the future, but for now, it’s a good thing.
