Bearmor Security – Free Firewall, 2FA, Malware Scanner & Vulnerability Alerts

Bearmor Security puts straightforward, professional WordPress security tools on small business and WooCommerce sites — without charging for essential features. The plugin is completely free: no PRO plan, no upsell tiers, no feature locks. Features other security plugins keep behind paid plans are free here: two-factor authentication with an authenticator app, daily vulnerability alerts, a plain-language AI security summary, a web application firewall and file integrity monitoring.

You get one clear dashboard that tells you whether your site is Protected, needs a Review, or needs Action — and links directly to the setting to fix it. Setup is quick and reversible, and each hardening rule explains what it does and what could break.

Firewall

• Blocks common SQL injection, XSS, path traversal and command injection patterns before WordPress loads the page

• Optional rate limiting per IP (logged-in users, WP-CLI and REST are never limited)

• Optional country blocking by 2-letter country code

• IP whitelist so you never lock out yourself or your office

• Honeypot fields on the login and comment forms catch bots without CAPTCHAs

Login protection

• Brute force protection: repeated failed logins trigger 5 minute, 30 minute and 24 hour lockouts, and repeat offenders are blocked permanently

• Login activity log with failed and successful attempts and their country

• Generic login errors so attackers can’t guess usernames

Two-factor authentication (2FA)

• Authenticator app codes (Google Authenticator, Microsoft Authenticator, Authy, 1Password, Bitwarden and any TOTP app)

• QR code setup on the user profile, generated on your own server

• One-time backup codes for a lost phone

• Email codes as an alternative method

• Choose which administrators must use 2FA; “remember this device for 30 days” option

Malware scanner and file integrity

• Daily scan of WordPress root, wp-content PHP files, the active theme, mu-plugins and uploads for backdoors, web shells and obfuscated code

• Core files checked against official WordPress.org checksums, including localized builds

• Alerts for changes in core, wp-config.php, the active theme and PHP files in uploads

• Quarantine, restore, or mark a file as safe in one click

Vulnerability alerts

• Daily check of WordPress core, plugins and themes against the WPVulnerability database

• Shows severity, CVE and the fixed version; one email for critical issues

Hardening (30 rules)

• Three tiers: Baseline, Access Hardening and Lockdown

• Security headers: X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, HSTS

• Disable XML-RPC, pingbacks, file editor, Application Passwords, user enumeration and REST user listing

• Block PHP execution in uploads, restrict the REST API to logged-in users (Contact Form 7 and WooCommerce checkout keep working)

• “Freeze Site” preset, hourly file tripwire and login IP allowlist for finished sites

• Each rule explains what it does, what it might break and how to test it; a built-in self-test checks that enabled rules work; changes can be undone for 24 hours

AI security summary

• A short, plain-language weekly summary of what is working and what needs attention, with links to the right setting

• Built from your site’s own facts: firewall blocks, failed logins, scans, updates, vulnerabilities and 2FA status

Activity log and uptime

• Audit log of logins and logouts, new and deleted users, plugin installs, activations and deletions, theme switches and file actions

• Uptime monitoring with history on the dashboard
