Spherical Defense is an API security solution that uses deep unsupervised learning to protect your APIs. Spherical Defense Express is deployed on AWS, takes just a minute to download and will be protecting your assets within two hours at the cost of $1 per hour. Once you have deployed your Spherical instance, it will immediately start listening for API traffic. It will stay in this mode for only as long as there is insufficient data to train the first security model. After receiving roughly 16,000 requests, it will move to the next stage. After sufficient data has been received, the system moves into training mode. This mode will result in a trained security model after roughly 6 hours, which will then be mounted for evaluation. As new data is received, the Spherical instance will train more models to account for natural changes in your API traffic over time. Once the first security model has been trained, it is mounted for evaluation.
