May use a combination of .htaccess and robots.txt. Read for more examples here. For a first line of defense would go with CloudFlare, too. Also for bots that scan for vulnerabilities, etc., consider this. Source: almost 3 years ago

Consider CloudFlare WAF (Pro subscription), and/or hardening your security with an established sec plugin like WordFence, Sucuri. (I personally prefer a lighter plugin.). Source: almost 3 years ago

Against hackers, I fancied this plugin instead of Wordfence. Source: almost 3 years ago

This is a free plugin that takes a different approach to security. Source: almost 3 years ago

After a successful clean up, install a security plugin to shield from future attacks. I personally prefer a more lightweight one like this. Source: about 3 years ago

Shortcodes Ultimate just allows me to build things with Gutenberg that I can't quite with Kadence, though I suppose I could use both, given that Kadence is so lightweight (only loading what it needs for the blocks of theirs used on each page). Source: almost 3 years ago

Shortcodes Ultimate (getshortcodes.com) is terrific--works really well both wrapped around and within Gutenberg blocks to add a lot of utility. Source: almost 3 years ago

I've tried most of those block plugins as well (both Getwid and Stackable were very nice--I also like Kadence quite a bit, as it is very lightweight and seems more refined in how its blocks display as compared to, say, Qubely), but Shortcodes Ultimate is still my favorite for Gutenberg.
