Cloudflare Spectrum for Secure Shell (SSH)

DDoS protection and better performance for SSH servers

With network capacity 23x larger than the biggest DDoS attacks ever recorded, Cloudflare Spectrum ensures SSH servers stay online and reliable in the face of attacks, while also accelerating SSH traffic.

BENEFITS OF CLOUDFLARE SPECTRUM FOR SSH

Increased uptime, better reliability

Distributed denial-of-service (DDoS) attacks can slow or stop service for SSH users, but Cloudflare Spectrum mitigates SSH DDoS attacks to ensure servers stay online.

Faster SSH connections

Cloudflare decreases the connection time for sessions and helps reduce latency. Users no longer have to struggle with slow performance or reconnect multiple times to speed things up.

No hardware or software changes

HOW IT WORKS

SSH connections are faster and more secure with the Cloudflare network

Cloudflare Spectrum runs between SSH servers and the Internet, and detects and mitigates DDoS attack traffic within seconds.

Using TCP optimizations, Spectrum also decreases the connection time for sessions and reduces latency. Connections terminate at the Cloudflare data center closest to the end user, making SSH faster and more reliable.
