A Distributed Denial of Service (DDoS) attack can take your application offline in seconds, causing massive financial and reputational damage. Many cheap VPS providers do not include native DDoS mitigation, leaving you exposed to extortion and downtime.
Infrastructure Level Protection
Platforms like Vultr and DigitalOcean offer robust network-level security and firewalls that can be configured to drop malicious packets before they overwhelm your server CPU. Their global Anycast networks help absorb and deflect massive volumetric attacks.
Application Level Mitigation
To protect against Layer 7 (application level) attacks, you should combine strong infrastructure with a reverse proxy like Cloudflare or a software firewall solution like Fail2Ban configured with custom rate-limiting rules in Nginx.
