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

Most security plugins hand you a dashboard full of alerts and expect you to know what to do next. Shield works differently.

It blocks threats automatically, repairs what it can on its own, and then shows you exactly what still needs your attention — ranked by impact, not volume. Less noise. More action.

🤖 Security That Runs Itself The most powerful thing Shield does is what it handles without you:

Automatic IP Blocking — every visitor is quietly scored as they interact with your site. Failed logins, firewall blocks, silentCAPTCHA failures, and other signals accumulate into a reputation score. When a visitor’s score crosses the threshold, Shield blocks them — automatically, without you lifting a finger

Automatic File Repair — when a file integrity scan finds a changed WordPress core file, Shield pulls the original from WordPress.org and restores it. Detected and fixed, without waiting for you to act

Automatic Bot Recognition — Shield identifies legitimate crawlers (Google, Bing, DuckDuckGo, Yandex, Apple) and known services (ManageWP, Pingdom, Stripe, CloudFlare) and never blocks them. Your SEO and monitoring tools keep working

🧭 Guided Security, Not Just a Dashboard Shield organises your security into four focused areas so you always know where to look:

Queue — things that need your attention, ranked by priority. Not everything at once — just what matters right now

Investigate — dig into blocked IPs, security events, and the specific signals that triggered each one

Configure — guided setup for each protection area, with clear recommendations matched to your site

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.

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.
