the problem
Outdated firewall features left gaps — and no one could maintain it
starting point
Existing Cloudflare setups relied on outdated firewall features, unmanaged rule logic and manual certificate handling, leaving gaps in protection and making the config hard to maintain.
what i did
Modern rules, managed rulesets, and SSL/DNS under control
- Migrated legacy firewall features (zone lockdown, IP access rules) to modern security custom rules with clearer, testable logic
- Configured Cloudflare's managed rulesets plus custom WAF and rate limiting rules to match each application's traffic profile and cut false positives
- Set up page rules and security custom rules for edge behaviour across access control, caching and bot protection
- Managed SSL/TLS end to end — edge and origin certificates, full/strict modes, certificate lifecycle
- Administered DNS records, zones and settings as part of the edge configuration
- Built edge logic with Cloudflare Workers, applied API Shield for API protection, and used lists and the trace utility for diagnostics and access control
