Wordfence Security (v8.1.4) is one of the most widely deployed WordPress security plugins, combining an endpoint Web Application Firewall (WAF), malware scanning, login hardening (including 2FA), and centralized monitoring capabilities through Wordfence Central. Because a security plugin operates at the most sensitive layers of a WordPress site—authentication flows, request filtering, filesystem integrity checks, and threat detection—its own code integrity and safety are absolutely crucial. That’s why Wordfence Security v8.1.4 achieving CleanTalk Plugin Security Certification (PSC-2026-64604) matters: it indicates the plugin has been audited and validated to meet strong secure-coding expectations and to resist major exploit classes that commonly affect WordPress plugins.

Key Features

WordPress Firewall (Endpoint WAF)

• Web Application Firewall that identifies and blocks malicious traffic at the WordPress endpoint layer.
• Brute-force protection with login attempt limiting and adaptive blocking.
• Premium Threat Defense Feed: near real-time firewall rules and malware signatures (free version typically delayed).
• Real-time IP Blocklist (Premium) to block known malicious IPs and reduce server load.
• Deep WordPress integration that helps prevent bypass scenarios seen in some edge deployments.

Security Scanner & Integrity Checks

• Malware scanner for WordPress core, themes, plugins: detects malware, backdoors, SEO spam, redirects, and injected code.
• File integrity comparisons against known repository baselines to identify unauthorized modifications.
• Repair & cleanup tooling to restore altered core/theme/plugin files and remove suspicious artifacts safely.
• Vulnerability awareness: alerts on known vulnerable plugins and on abandoned/closed plugins (important operational risk signal).

Login Security Hardening

• Two-Factor Authentication (2FA) using TOTP-compatible apps.
• Login CAPTCHA to reduce bot pressure.
• XML-RPC controls (disable or add additional security controls).
• Compromised password checks for administrator accounts (policy enforcement).

Audit Logging and Monitoring (Premium Features)

• Security audit log tracking sensitive actions: user changes, plugin/theme install/update, config changes, content changes.
• Tamper-resistant centralized storage via Wordfence Central (Premium).

Wordfence Central (Multi-site Security Operations)

• Central dashboard for multiple sites:
  • centralized visibility and configuration templates
  • configurable alerting (email/SMS/Slack)
  • event tracking (admin logins, attack surges, breached password usage)
• Operationally valuable for agencies and enterprises managing multiple WordPress installs.

Security Assurance

Security plugins must themselves be hardened against the same threats they mitigate, because they:

• process untrusted request data (WAF paths)
• handle authentication controls and admin settings
• read and compare filesystem contents
• store/aggregate security logs and metadata

Wordfence Security v8.1.4 has earned CleanTalk Plugin Security Certification (PSC-2026-64604), confirming it was assessed for resilience and safe implementation.

The plugin has been successfully tested for:

✅ Information Leakage Vulnerabilities

✅ SQL Injection Vulnerabilities

✅ Cross-Site Scripting (XSS) Attacks

✅ Cross-Site Request Forgery (CSRF) Attacks

✅ Authentication & Authentication Bypass Vulnerabilities

✅ Privilege Escalation Vulnerabilities

✅ Buffer Overflow Vulnerabilities

✅ Denial-of-Service (DoS) Vulnerabilities

✅ Data Leakage Vulnerabilities

✅ Insecure Dependencies

✅ Code Execution Vulnerabilities

✅ File Unauthorized Access Vulnerabilities

✅ Insufficient Injection Protection

PSC-2026-64604 provides a strong signal that Wordfence v8.1.4’s codebase and exposed surfaces were reviewed against these exact risk categories.

Conclusion

Wordfence Security v8.1.4 delivers a comprehensive security stack for WordPress—endpoint firewalling, malware detection, login security (including 2FA), auditing, and centralized operations. With CleanTalk Plugin Security Certification (PSC-2026-64604), Wordfence is additionally validated for secure implementation and resistance against a broad range of critical vulnerability classes—making it a stronger choice for site owners who need both powerful protections and confidence in the security of the protection layer itself.
