TCP Ping vs Traditional ICMP Ping
While traditional ping uses ICMP Echo packets, modern firewalls and cloud providers frequently block ICMP to mitigate DDoS attacks. Our TCP Ping establishes real socket handshakes on active service ports, providing an accurate measure of true application responsiveness.
