How to Make Your WordPress Forms Secure with Pie Forms

WordPress comes with a number of contact form plugins offering multiple features. But not all the plugins provide the same level of security and service. Therefore, it is important to choose your contact form plugin wisely on the basis of the various security features the plugin offers.

With the below-given features of Pie Forms, you can add an extra layer of security to your forms to keep the data safe and reduce spam.

  2. Form Validation
  3. Full Spam Protection
  4. Limit Form Entries From A Device
  5. Secure File Upload Forms

1. Block Users

There can be several reasons for blocking users from your website. The most important is when you are tired of bots and trolls bogging down your website. You can eliminate spam and protect your website by instantly blocking them.

Using the block user feature of Pie Forms, you can block them in three ways:

  1. By username

2. Form Validation

Forms can be validated in two ways:

Server-side validation

Server-side scripting languages are used, such as ASP.NET and PHP

Client-side validation

The browser-side scripting language is used, such as JavaScript.

The client-side validation is used for a better user experience but it provides no actual security. It cannot protect your application from hostile bot attacks if the user turns off the JavaScript. This also means the doors are then open for spammers.

But Pie Forms comes with server-side validation for extra secure submissions of forms. So even if the user blocks the JavaScript, you are in the safe zone!

3. Full Spam Protection

 There is no generic way to identify the actual human or bot while submitting the forms, but by adding several security features like Google ReCaptcha, it becomes easy to distinguish. It is one of the best ways to keep automated spammers away from your site.

Pie Forms has some powerful Captcha Support, including:

reCaptcha v2 and v3

Pie Forms supports both v2 and v3 of Google reCaptcha. ReCaptcha v2 comes with a check box asking I am not a robot, whereas v3 is invisible.

HoneyPot has been around for decades. It is a computer system used to detect attacks.

Pie Forms comes with built-in HoneyPot protection. It is an invisible field in the forms and provides protection to your forms from the bots. If the field is not empty on the form submission, it is filled by a bot.
