Laravel隐形验证码安全吗?

Question

在Laravel 7中使用 "albertchtinvisible-recaptcha "的刀片应用。captcha'to pages with common access as login, regsiter, contact_usand added captcha in for definition of all these forms, like:

<form method="POST" action="{{ route('login') }}" aria-label="{{ __('Login') }}">
    {{ csrf_field() }}
    @captcha('en')

Can I consider all these pages safe from externall attacks?Have I to take some additive steps? If yes, which ?

Thanks!
