A DDoS protected VPS is a virtual private server that includes DDoS mitigation, meaning it’s located inside a network or data center resistant to DDoS attacks.
This requires massive bandwidth capacity and special hardware firewalls that are designed to stop malicious packets before they can do any harm. Most virtual servers are unprotected and therefore vulnerable to DDoS attacks.
If you host your application on a secure DDoS protected VPS, it means that it’s not vulnerable to cyber attacks and can’t be taken down by malicious attackers, which could be competitors or simply cyberpunks. DDoS is even used to blackmail online shops sometimes.
For reference, check out some of the threats against both Daybreak Games and Blizzard Entertainment by the group known as “Lizard Squad”. If you choose a Rivalhost product, you don’t have to worry about these things anymore and it’s often a better alternative to remote protection and provides higher uptime than anything else.
