Not counting DLC and Elite suits, all Security RIG variations offers the highest damage resistance of all RIGs wearable.The Security Suit has the most palette swaps in Dead Space 2, even excluding DLC suits.A variant of this suit appears in Dead Space 3 used by Lunar police officers on New Horizons colony which features a lighter shade of blue, gold trim, and decals likely indicating an officer's unit. They lack a mounted holo projector, but as seen with various deceased officers, there is still a module on the chest piece of the suit capable of displaying RIGlink.

The security suits however are generally more well-armored, though seemingly only focused on knife and blunt weapon protection, given that the armor mainly covers the most vital areas of the body and little else.

All of the security personnel encountered in Dead Space 2 use suits that seem to be on par with Standard Engineer Suit in terms of overall protection from Necromorph attacks.

However, the Zealot RIG gives its 5% Damage Bonus to the Force Gun or Zealot Force Gun. Offering 15% damage resistance and 15 inventory slots. The Zealot RIG with the Collector's Edition appears to be the equivalent of the Security Suit.All Security Suits displays a wanted order of Nolan Stross on their chest holo projector.
