Sure, think of the rule set as a filing cabinet. First, list every rule by how often it hits, like your tools by weight. Next, cluster them by direction—outbound, inbound, VPN, internal—and remove any that are never used, that’s your waste. Then, for each cluster, order by frequency: the rule that fires most often goes first; that reduces latency because the engine stops scanning sooner. Finally, apply a “no‑override” envelope: if a broad rule covers a set of traffic, tighten it with a narrower rule only where you really need it. Treat the whole thing like a circuit diagram—clear, modular, no stray wires. That’s the geometry that keeps firewalls lean and predictable.
