How to secure Forms from Spam submissions?

Hi, I'm currently having issues with getting too many spam submissions on my form for my business website. Do you guys still offer the google invisible recaptcha plug-in? If so can I still have that available even when I'm embedding the form onto my custom site?

You can follow the suggestions below:

1. Using the Captcha field in the form editor. This is the most common and efficient way to check if the person doing the submissions is a real person. Yes, reCaptcha is still supported.

2. You can also set up the form to have Unique Submission limits.

Loose Check-> Limits the computer/device where the form is being filled out using the current cookies being used. This will prevent to do multiple submissions unless they clear their cookies or use another web browser.

Strict Check-> Limits the computer/device where the form is being filled out using its IP Address, to where one IP can only have one submission.
