原文外掛簡介
Premium Security. Zero Cost.
Vigilant provides enterprise-level WordPress security features completely free. No premium version, no upsells, no hidden features behind paywalls.
Protect your site with a complete security suite: firewall, two-factor authentication, brute force protection, security headers, file integrity monitoring, closed plugin detection, malware detection, user management, security audit logging, under attack mode and much more.
Instant Protection
Once activated, Vigilant immediately applies essential security measures:
Firewall rules against common attacks (SQL injection, XSS, file inclusion)
Security headers for browser protection
Login attempt monitoring
XML-RPC blocking
WordPress version hiding
Sensitive file protection (.htaccess, wp-config.php)
Automatic backup of your existing configuration files
One-Click Security Presets
Choose a preset and get protected instantly:
Standard – Balanced security suitable for most websites. Enables all modules with sensible defaults that won’t interfere with normal site operation.
Maximum Security – Strictest settings for high-security sites. Tighter rate limits, stronger CSP rules, mandatory admin notifications. May require fine-tuning for some setups.
You can always customize individual settings after applying a preset.
Under Attack Mode
Is your site under active attack? Activate Under Attack mode with one click and stop malicious traffic instantly:
JavaScript challenge – Every visitor must pass an automatic browser verification before accessing your site. Real browsers solve it in seconds, bots get blocked completely
Aggressive rate limiting – Requests limited to 30 per minute with 15-minute blocks for offenders
HTTP method restriction – Only GET, POST, and HEAD allowed. PUT, DELETE, PATCH, OPTIONS, and TRACE are blocked
Empty user agent blocking – Requests without a user agent header are rejected
Full XML-RPC lockdown – All XML-RPC access is blocked during the attack
REST API restriction – Only authenticated users can access the REST API
Auto-deactivation – Mode automatically turns off after 4 hours so you never forget it’s on
Email notifications – Get notified when the mode is activated and deactivated
HMAC-signed cookies – Verified visitors receive a cryptographically signed cookie so they only see the challenge once
Under Attack mode works independently from your preset configuration. Your regular security settings are preserved and restored when the mode deactivates.
Core Security Features
Two-Factor Authentication (2FA)
Add a second verification step to your WordPress login. Choose the method that works best for your team:
Authenticator app (TOTP) – Google Authenticator, Authy, Microsoft Authenticator, or any TOTP-compatible app
Email codes – One-time 6-digit verification codes sent via email
QR code setup directly in user profiles
10 backup codes for emergency access if you lose your device
Configurable grace period for users to set up their authenticator app
Trusted devices feature – optionally allow users to skip 2FA on recognized devices for 30 days
Role-based enforcement – require 2FA for administrators, editors, or any role
Exclude specific users from 2FA requirements
Admin tool to reset TOTP for users who lost their authenticator
Configurable code expiry, attempt limits, and email sender name
User notification emails when 2FA is enabled or method changes
Firewall Protection
Block malicious requests before they reach WordPress:
SQL injection blocking
XSS (Cross-Site Scripting) attack prevention
File inclusion protection (LFI/RFI)
Directory traversal blocking
Bad query string filtering (catches generic suspicious patterns the specific blockers miss)
Bad bot detection and blocking
Block requests with empty user agent
Block legacy HTTP/1.0 requests (almost always automated tools, never modern browsers)
Rate limiting against DDoS and brute force, with optional progressive lockouts
IP whitelist and blacklist management (with CIDR ranges)
User-Agent whitelist and blacklist with partial matching
HTTP method restriction
Server-level file protection via .htaccess: block direct access to wp-config.php, .htaccess, wp-includes/, and sensitive files (.log, .sql, .bak, .ini, debug.log, readme.html, etc.), and optionally wp-cron.php external access
Block PHP execution in /uploads (one of the most common post-exploit vectors)
Disable directory browsing
Login Security
Stop unauthorized access attempts:
Limit login attempts with configurable thresholds
Progressive lockouts – longer blocks for repeat offenders
Custom login URL – hide wp-login.php from bots
Login URL change notifications to all admin-area users
Hide login error messages – don’t reveal valid usernames
XML-RPC disable – block this common attack vector, with a separate toggle for just the pingback method if you still need other XML-RPC features
Application passwords control
Email notification when an IP is blocked for exceeding login attempts
Admin login notifications via email
IP whitelist for trusted locations
User Security
Comprehensive user account protection:
Block insecure usernames (admin, test, root, etc.) on new registrations
Warn about existing users with insecure usernames so you can rename or remove them
Block author scanning — intercept ?author=N URLs so WordPress doesn’t redirect them to /author/USERNAME/ and leak the login slug
Force strong passwords with minimum length
Password expiration with configurable intervals
Password history – prevent reusing old passwords
Force password reset — by specific users, by role, or all users (post-hack recovery)
Session limits – control concurrent logins per user
Session management – view and revoke active sessions
Email verification for new registrations
Registration approval workflow – manually approve new users
Admin account monitoring – alerts for new admins, email changes, password changes, privilege escalation
Display name protection – prevent exposing login username publicly
Security Headers
Achieve Grade A security ratings:
Content Security Policy (CSP) with visual builder and Report-Only mode for safe testing before enforcing
HSTS (HTTP Strict Transport Security) with includeSubdomains and preload options
X-Frame-Options – prevent clickjacking
X-Content-Type-Options – prevent MIME sniffing
X-XSS-Protection – kept available for auditors that still check it (deprecated in modern browsers, superseded by CSP)
Referrer Policy control
Permissions Policy (camera, microphone, geolocation, payment, USB)
Cross-Origin policies (COEP, COOP, CORP)
HTTPS enforcer with automatic mixed content fix
Server fingerprint hiding — Server: Apache/x.y.z header neutralized, X-Powered-By and other fingerprinting headers stripped from responses
File Integrity Monitoring
Detect unauthorized changes to your files and compromised plugins:
WordPress core verification against official checksums
Plugin and theme file monitoring with WordPress.org checksums
Critical config files (wp-config.php, .htaccess) monitored against baseline — detects code injection even in files with no official checksum
Closed and removed plugins detection — daily check against the WordPress.org plugin repository, flags any installed plugin closed for malware, security issues, guideline violations or supply chain compromises. Detects two flavors of closure: explicit with closure date and reason, and “removed” (metadata hidden by wp.org, typical of Security Issue takedowns). Per-slug Ignore for legacy plugins you can’t uninstall yet
Line-level diff view of changes, with per-file approval workflow
Suspicious code scanning for plugins and themes without checksums
Extra file detection in plugins and themes (files not in original distribution)
Two-level detection: strict obfuscation combos for plugins, broad patterns for uploads
Uploads directory scanning for PHP files, double extensions, and .htaccess
Root directory scanning for non-core PHP files (common attack vector)
Smart .htaccess classification in uploads – distinguishes dangerous rules from protective ones
String concatenation obfuscation detection
Configurable notification levels (all issues, suspicious only, or disabled)
Ignore list to dismiss known files from results
Excluded paths and file extensions
Scheduled automatic scans (daily, weekly)
HTML formatted email alerts with severity sections, including a dedicated section for closed plugins
Security Audit
Track everything happening on your site:
Successful and failed login attempts
Two-factor authentication events
User account changes (creation, deletion, role changes)
Content modifications (posts, pages)
Plugin and theme activations/deactivations
Security events and blocked threats
HTTP request method tracking and filtering (GET, POST, PUT, DELETE)
Enhanced log detail popup with grouped sections and quick actions
One-click add IP or User-Agent to firewall whitelist/blacklist from log entries
Direct IP lookup links to AbuseIPDB
Configurable retention period
Export logs to CSV
Filter by event type, severity, request method, or date
Security Check
On-demand security audit built into the Dashboard. No external services, no accounts, no API keys — everything runs on your server:
40+ checks across 6 categories: SSL/TLS, HTTP Headers, WP Exposure, Access & Auth, Sensitive Files, and Internal Checks
Single 0–100 score with A–E grade, plus per-category breakdown and explanatory details for every check
14 exclusive internal checks impossible from the outside: PHP end-of-life status, pending updates, inactive plugins, closed or removed plugins in the WordPress.org repository, file permissions, default salts detection, wp_ table prefix, admin username, administrators without 2FA enrolled, module status, recent audit errors, and last File Integrity scan result
DNS-only reputation lookup against Spamhaus ZEN, Barracuda BRBL and SpamCop SCBL (informational — listings are flagged but don’t deduct from the score)
Two-phase scan: fast local checks appear in under a second, remote checks stream in as they complete
Weekly automatic scan with opt-in email alert if the score drops by 10+ points or a new critical check starts failing
30-scan history with sparkline trend and delta chip so you can see how changes to your site affect security over time
“Go to setting” fix link on every failing check — jump straight to the exact Vigilant field that resolves it, with a visual pulse on arrival
Smart header diagnostics report “configured but not being served” when a cache/CDN overrides your headers, instead of just marking it green or red
WordPress Hardening
Layered protection at the WordPress level — admin, content, head, feeds, and database:
Lock down the WordPress admin: disable the built-in plugin and theme file editor, block installations and updates from the admin area, and force HTTPS for the admin area. Compatible with any hosting layout, including managed hosts and custom configurations that already define some of these settings on their own — Vigilant always respects values already in place and never overrides them
Disable WordPress’s internal page-view cron when you already have a real server-side cron job configured, removing the small performance hit caused by triggering scheduled tasks on every visit
Dashboard warning when debug mode is left enabled in production, so error output never leaks to visitors
Hide your WordPress version everywhere it can leak: from the HTML head, from RSS and Atom feeds, and optionally from every script and style URL on the front-end. The asset cleanup is precise — it only strips the WordPress version itself, leaving versions added by plugins and themes intact so their cache busting keeps working
Automatic daily removal of readme.html, license.txt, and licencia.txt from the WordPress root, which otherwise expose your WordPress version to anyone visiting them directly
HTML head cleanup — remove the RSD link, Windows Live Writer manifest, shortlink header, and REST API discovery link
Database hardening — security check for the default wp_ table prefix and one-click rename tool with full backup before the change
Comment security — honeypot field against spam bots, force moderation on every new comment, close comments on old posts after a configurable number of days, disable pingbacks and trackbacks
Feed management — completely disable RSS and Atom feeds, or only disable them when the site has no published content
REST API Security
Control API access to your site:
Three access modes: public (default WordPress behavior), authenticated only (closes the API to anonymous visitors), or selective (custom allow/block lists)
Block user enumeration via /wp-json/wp/v2/users
Protect any list of sensitive endpoints from anonymous access
Per-plugin compatibility toggles so authenticated mode doesn’t break the front-end: WooCommerce, Contact Form 7, Gravity Forms, WPForms, Elementor, Jetpack. oEmbed and Site Health endpoints stay accessible by default so embeds and the Tools > Site Health screen keep working
Security Tools
Utilities included:
Database Backup – Download a full or partial database backup as ZIP with table selection
Database Prefix Change – Change the default wp_ prefix to a random secure prefix
Export/Import Settings – Transfer your configuration between sites
Manual Backup – Create backups of .htaccess and wp-config.php on demand
Reset to Defaults – Start fresh with one click
Safe by Design
Automatic Backup System
Your existing .htaccess, wp-config.php, and robots.txt are automatically backed up before any modifications. Backups include integrity verification (MD5 checksums) and are stored safely in wp-content/vigilante-backups/, persisting through plugin updates.
Clean Rollback
When you deactivate Vigilant, all security rules are automatically removed and your original configuration files are restored. No leftover code, no broken sites.
