Shield Security – Smart Bot Blocking, Brute-Force Login Protection & File Scanning for WordPress

Reports — a clear view of what Shield has blocked, detected, and repaired over time

The goal: guide you quickly towards action, not bury you in data.

🛡️ Free Protection Bot Blocking & Firewall

silentCAPTCHA — blocks bad bots on login, registration, lost password, and comment forms using passive signals invisible to real visitors. No CAPTCHA keys. No external requests. No JavaScript that breaks your forms. Everything runs on your server (GDPR friendly).

Firewall rules blocking common WordPress attack patterns — SQL injection probes, known exploit signatures, suspicious request parameters

XML-RPC protection — disable or restrict entirely, including pingbacks and trackbacks

REST API firewall — block unauthenticated requests

Fake crawler detection — identifies bots spoofing legitimate search engines

Login & Account Security

Two-factor authentication (2FA) — email codes, Google Authenticator, or YubiKey OTP for all users

Brute force protection with configurable login attempt limits and cooldown

Session locking — tie sessions to a browser or IP to stop account theft after a successful login

User enumeration blocking — closes off ?author= probes used to harvest usernames before an attack

Scanning & Integrity

Core file scanning — compares WordPress core against official checksums and repairs changed files automatically

Suspicious PHP detection — flags PHP files in locations where they have no business being

Abandoned plugin detection — identifies unmaintained plugins most likely to carry unpatched vulnerabilities

Visibility & Control

Security Admin PIN — lock Shield’s own settings so other administrators cannot quietly weaken your configuration

Security activity log — logins, user changes, plugin and theme events, post edits, and suspicious requests: Everything in one clear view

IP Rules — automatic & manual block and bypass rules, CIDR range support, full per-IP request history

🤝 CrowdSec Integration Shield is the only WordPress security plugin with a native CrowdSec integration. CrowdSec aggregates threat signals from millions of sites into a shared IP reputation network — your site blocks known attackers before they ever probe you, using intelligence far beyond your own traffic history.

ShieldBACKUPS Disaster Recovery ShieldPRO includes ShieldBACKUPS: fast, off-site WordPress backups built for recovery after hacks, broken updates, or server failure.

Your backup is kept away from the site it protects, so you have a clean recovery path when WordPress itself is down, damaged, or under attack.

There are no cloud storage costs, backups are encrypted and copied securely, and there are no storage API keys or authentication details stored on your WordPress site.

Who It’s For Shield suits site owners, agencies, and MSPs who want protection that runs itself — not a plugin that demands constant attention to be useful.

If you have been burned by security plugins that generate more noise than protection, or dashboards that tell you everything is wrong without telling you what to fix, Shield was built to be the alternative.

Partnerships & Integrations We believe that silentCAPTCHA is one of the simplest and most powerful solutions available today for all WordPress site owners to block and eliminate automated bot spam.

That’s why we’ve started a collaboration campaign with other WordPress plugin developers to adapt their plugins to natively support Shield’s silentCAPTCHA solution, alongside Google reCAPTCHA & Cloudflare Turnstile.

When you use one of the products from any of our partners, you will be able to activate Shield’s silentCAPTCHA bot spam protection so that your forms are protected from automated spam. You won’t need any site/API keys, custom integrations, or JavaScript that can break your forms. It all works automatically for you when you enable the feature.

As of this release, we have partnered with the following WordPress form providers:

Everest Forms v3.5+

Easy Form Builder v4+
