Firewalls & Outer Layer Defences

Cloudflare WAF + Wordfence for WordPress Member Experience Solution

Executive Summary

This document outlines the strategic advantages of Agend Systems' dual-layer security approach utilising Cloudflare's Web Application Firewall (WAF) alongside the Wordfence security plugin for our WordPress-powered member experience website solution. This combination creates a robust defence-in-depth strategy that provides multiple layers of protection against diverse threat vectors, ensuring our members' data remains secure and their experience remains uninterrupted.

Agend Systems Security Architecture

Layer 1: Cloudflare WAF (Network Edge)

Cloudflare's WAF operates at the network edge, providing the first line of defence against attacks before they reach Agend Systems' web servers. For our member experience website solution, this critical perimeter security ensures malicious traffic is filtered before it ever reaches our hosting infrastructure.

Note

Cloudflare have a number of plans available with an entry-level free version deployed by default. Please discuss your individual needs with us and whether Cloudflare paid plans may offer.

Layer 2: Wordfence (Application Layer)

Wordfence operates directly on Agend Systems' WordPress installation, providing application-level protection and WordPress-specific security features. This layer protects the member experience platform itself, ensuring secure member interactions and safeguarding sensitive member data.

Strategic Benefits for Agend Systems' Member Experience Solution

1. Defence-in-Depth Protection

Agend Systems' implementation of Cloudflare WAF and Wordfence creates multiple security checkpoints:

  • Edge Protection: Cloudflare filters malicious traffic at the network edge before it reaches our hosting infrastructure
  • Server-Level Security: Wordfence provides an additional security layer directly on our member experience platform
  • Application-Specific Protection: Wordfence's WordPress-specific security features address unique CMS vulnerabilities that could potentially impact our members

This multi-layered approach ensures that if one security measure fails, others remain in place to protect the Agend member experience website solution and our members' data.

2. Complementary Security Features

Cloudflare WAF Provides:

  • DDoS Attack Mitigation: Enterprise-grade protection against volumetric attacks
