No, we don't directly protect against DDoS (Distributed Denial of Service)
For Elite and Enterprise customers, however, the WAF (Web Application Firewall) helps mitigate DDoS amongst other kind of attacks.
We suggest adding a CDN on top of your project to protect against DDoS.
If you need granular control, a WAF that allows for VCL rules that can mitigate attacks and handle large amounts of traffic can be a good option.
