Independent WordPress security
Prevent attacks before they become emergencies.

Start free. Upgrade when your site needs more. Money-back guarantee.
Start with your worry
What are you protecting against?
Malicious requests die at the front door.
Shield’s firewall inspects every request, and silentCAPTCHA turns bots away before they try anything. No puzzles for humans, ever.

Get your site back, fast.
Honest security plans for the day prevention isn’t enough: a bad update, a hosting failure, a brand-new attack.

How sites actually get hurt
Bots flood your logins and forms.
silentCAPTCHA and rate limiting stop them before the first guess — no puzzles for humans.
Explore bot blocking →A plugin you run is vulnerable.
Shield auto-updates as soon as the fix ships. You don’t even have to know about it.
Explore auto-updates →Malware hides and works for someone else.
MAL{ai} spots malicious code the moment it lands — even malware nobody has seen before.
Explore malware scanning →Someone logs in as one of your users.
Two-factor authentication and session controls make a stolen password worthless.
Explore login protection →There’s no clean copy of your site to go back to.
Backups you can actually restore. A bad hour, not a bad month.
Explore backups →You run thirty sites. One of them is the weakest link.
One security policy, synced everywhere. No per-site babysitting.
Explore multi-site →Don’t take our word for it
“I can not say enough about Shield Security’s service and product. It’s always a big ordeal to maintain the security of my wp site and I have not found a plugin/service that can keep my sites safe, detect file changes & remove them automatically until I found Shield Security.

FAQ
Straight answers before you decide.
Do I need to be technical to use Shield?
No. Shield ships with sensible defaults and a guided setup. The deep controls exist, but ignoring them is a valid strategy.
Will Shield slow down my site?
No — usually the opposite. Bots eat real server resources. Blocking them gives that back.
Is Free actually useful, or a teaser?
Very. Core hardening and bot defence, free forever. Add more protection when your site becomes critical.
What’s the difference between Free and Plus?
Free covers core protection. Plus adds everything else: silentCAPTCHA, MAL{ai}, vulnerability auto-updates, complete login protection, and recovery.
Will it lock out my real users?
silentCAPTCHA works invisibly — humans never see a puzzle. Locking out real users is the failure we designed against first.
What does Shield not do?
It isn’t a CDN, it won’t write your privacy policy, and it can’t protect a password taped to your monitor. If you need something Shield doesn’t do, we’ll say so.
What if I manage several sites?
One licence, one security standard, every install. See the Enterprise/Agency route on the pricing page.
What if Shield isn’t right for me?
Money-back guarantee, no hoops. We’re not interested in keeping money from people we didn’t help.
