What is DDoS protection and do I need it?
DDoS protection filters attack traffic upstream of your server so legitimate requests still arrive. It has to be always-on to be useful — mitigation that activates after an attack starts has already let you go down. OnionVPS includes up to 12 Tbps of L3/L4 scrubbing at every tier, including the $4 plan.
There are two distinct layers. Network-level attacks flood your connection with volume and are stopped by upstream scrubbing. Application-level attacks send requests that look legitimate but are expensive to answer, and need filtering that understands the protocol.
Game servers, anything crypto-adjacent, and anything with a competitor are attacked routinely. The attacks are cheap to launch and often come from teenagers with a $10 subscription, which is precisely why protection has to be standard rather than an upgrade.
