DNS-Layer Filtering vs Full URL Path Categorization
Comparing lightweight DNS query filtering with deep HTTP/HTTPS full-path web categorization.
Architectural Context & Problem Statement
DNS filtering blocks malicious domains before connection establishment, while full URL inspection analyzes specific sub-paths on shared domains.
Architectural Comparison Matrix
| Evaluation Criterion | 4CGuard Architecture | Alternative / Legacy Architecture |
|---|---|---|
| Inspection Depth | Domain-level only (e.g. `github.com`) | Full URI path (e.g. `github.com/malware/payload.exe`) |
| Encrypted Traffic | Operates on plaintext DNS or DoH/DoT | Requires SSL/TLS decryption for full HTTPS path |
| Latency Impact | Zero latency impact on web browsing stream | Requires inline proxy inspection |
Recommended Migration Roadmap
Extract existing rulebases, NAT mappings, and address objects for automated normalization.
Convert static IP-based rules into identity-aware Layer 7 application policies.
Deploy 4CGuard in passive/monitor mode to verify traffic matching and zero rule drop errors.
Execute scheduled maintenance window cutover and enable full single-pass IPS and SSL inspection.
