Helping to Make the Connections That Matter.

We've had DDoS protection for a long time and understand it's an important part of total customer satisfaction.

Since there was no additional cost to increase the number of upstream connections [with JSI's Smart Advantage DDoS Mitigation service], we can continue to grow our business without incurring additional charges to mitigate attacks with the added benefit of detailed upstream monitoring.
