Gladius is currently in the ICO stage and this coin comes up with a solution to a real problem for website owners. According to Gladius official website:
Gladius is the decentralized solution to protect against DDoS attacks by allowing you to connect to protection pools near you to provide better protection and accelerate your content. With an easy to use interface as well as powerful insight tools, Gladius enables anyone to protect and accelerate their website.
With what I can make sense of, Gladius is trying to create a Content distribution and Protection service where you make money if you have a fast internet connection and spare computer. For those who are familiar with crypto currency mining this is kind of similar but instead of utilizing your hardware power you actually gives your internet bandwidth to the network and you get paid accordingly. Gladius has a calculator on their website which gives you an estimate on how much you can earn by join a pool of network.
