WAF Alternatives for Django Applications

Since you're looking for alternatives to Sqreen for your Django applications, here are some effective WAF options to consider:

Cloudflare WAF

You mentioned you're already using Cloudflare for DNS management, which makes their WAF a natural choice:

• Integrates well with existing Cloudflare services
• Provides protection against common vulnerabilities (OWASP Top 10)
• Offers DDoS protection
• Has customizable rule sets

Other Recommended Alternatives

ModSecurity

• Open-source WAF that can be deployed with Nginx or Apache
• Highly customizable rule sets
• Can be used with the OWASP Core Rule Set
• Example configuration with Nginx:

NGINXCopied
# Load ModSecurity module
load_module modules/ngx_http_modsecurity_module.so;

server {
    modsecurity on;
    modsecurity_rules_file /etc/nginx/modsecurity/main.conf;
    # Other server configuration
}

AWS WAF

• Good option if you're already in the AWS ecosystem
• Integrates with CloudFront, Application Load Balancer, or API Gateway
• Provides protection against common web exploits
• Customizable rules and managed rule sets

Django-specific Security Options

Django Security Middleware

Enhance your application's security with Django's built-in security features:

PYTHONCopied
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    # Other middleware
]

# Security settings
SECURE_HSTS_SECONDS = 31536000
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_CONTENT_TYPE_NOSNIFF = True
SECURE_BROWSER_XSS_FILTER = True
SECURE_SSL_REDIRECT = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
X_FRAME_OPTIONS = 'DENY'

Django-CSP (Content Security Policy)

PYTHONCopied
MIDDLEWARE = [
    # Other middleware
    'csp.middleware.CSPMiddleware',
]

CSP_DEFAULT_SRC = ("'self'",)
CSP_SCRIPT_SRC = ("'self'",)
# Additional CSP settings

Consider combining a cloud WAF solution like Cloudflare with Django's built-in security features for a layered security approach.
