This plugin uses the superperms for permissions (without, it defaults to everything usable by everyone, teleblock shields bypassable by ops). Also (optionally) uses the Factions plugin for faction-based filters on some redstone devices, Towny for city and nation-based filters, and (optionally) Vault for per mechanism costs.
Fortification is a redstone focused plugin aimed at leveling the playing field in pvp by providing defenders with the tools necessary to mount a proper defense. This being said, many of these features serve non-combat purposes as well. Fortification can link into the Factions and Towny plugins to provide additional filters to help differentiate between friends and foes and Vault to bring additional cost to mechanisms.
This plugin optionally uses permissions (without permissions it defaults to everything usable by everyone, teleblock shields bypassable by ops).
