A secure hosting platform

Unlike form builders, finding a secure hosting platform is a hectic task. You need to choose from so many options out there that can surely make you confused. Also, there are quite a few factors to consider when choosing the right hosting platform for your WordPress site. 

The most important things you need to keep in mind are security measures, server reliability, backup options, and so on. You’ll also need to consider the offerings of your hosting company, like free or shared WordPress hosting, VPS (Virtual Private Server), dedicated server hosting, etc. 

SiteGround is one of the most popular and highest-rated hosting providers in WordPress. Before choosing any hosting service, you should know all the protection layers inside the providers. 

Wp Engine, HostGator are also famous for their service in the arena. Also, keep an eye if your hosting service provider offers an SSL certificate or not. SSL (Secure Socket Layers) gives an extra level of security by switching from HTTP to HTTPS.

After choosing the right contact form builder and hosting provider, here comes the part of creating secure online forms. As you’ve installed and activated Fluent Forms in your WordPress dashboard, now is the time to configure it as spam-proof.

Fluent Forms allows you to enable Double opt-in with a simple check box. Head over to the Global Settings and select Double Opt-in Settings; check it to enable. Then write a confirmation email to give your users some instructions. Save it, and you’re good to go.

        Unfortunately, it is not always sufficient to do all the things you mention in this article. In the EU, it may sometimes be necessary for personal data to be encrypted. This could be your personal identification number or similar. How can you encrypt such (or any) field in FluentForms?
