# What is Armor?

Armor is a protocol that allows users to protect funds held on a variety of DeFi (Decentralized Finance) protocols in the case of hacks in an easy, self-adjusting, pay-as-you-go manner. 

Our system detects any changes in your balance on supported protocols and prompts you to adjust your plans accordingly. 

You are billed by the second for the exact amounts protected on each protocol so you'll never pay any more than necessary. 

If a platform you hold funds on is hacked, and your claim is approved, you will be fully compensated for losses as per Nexus Mutual policies.
