DDoS Detection for cPanel/WHM
Install ftagent directly on your cPanel server. Protect every hosted site with real-time DDoS detection, automated firewall rules, and instant alerts. One command to install, nothing to configure on cPanel itself.
How It Works
Setup
Three steps to DDoS protection
Sign up for Flowtriq
Create a free account and get your deploy token from the dashboard. The 14-day trial includes all features with no credit card required.
Install ftagent on your server
SSH into your WHM server and run one command:
curl -sL https://get.flowtriq.com | sudo bash
The installer detects your OS, installs ftagent, and walks you through the deploy token.
See attacks in your dashboard
Within minutes, traffic data appears in Flowtriq. Baselines build automatically. Attacks are detected, classified, and trigger your configured alert channels and mitigation policies.
Capabilities
What you get with this integration
Sub-Second Detection
ftagent reads kernel-level network counters every second directly on your cPanel server. Attacks are detected in under 1 second, not minutes. No NetFlow latency because the agent runs on the same machine.
Attack Classification
Every detected attack is classified: SYN floods, UDP amplification, DNS reflection, NTP monlist, ICMP floods, GRE floods, fragmentation attacks, and more. Each with protocol-level confidence scores.
Automated Firewall Rules
ftagent deploys iptables or nftables rules on your cPanel server to drop attack traffic at the kernel level. Rules are surgical: they target specific attack signatures without affecting legitimate web traffic.
Multi-Channel Alerting
Get notified instantly via Discord, Slack, PagerDuty, OpsGenie, email, SMS, or webhooks. Alert messages include attack type, target IP, traffic volume, and recommended actions.
PCAP Capture
Because ftagent runs directly on the server, it can capture full packet data during attacks. Use PCAP evidence for forensic analysis, abuse reports, and upstream provider escalation.
CSF Compatible
ftagent manages its own iptables chain and never modifies CSF rules. Both run simultaneously without conflict. During attacks, ftagent adds temporary rules and removes them after the attack ends.
Why It Matters
Why shared hosting servers need DDoS detection
One attack affects everyone
A DDoS attack targeting one site on your shared hosting server affects every other site on that server. Without detection, you do not know which account is being targeted or what kind of attack it is. You just see "the server is slow" tickets.
Faster incident response
When an attack hits, Flowtriq tells you exactly what is happening: the target IP, attack type, traffic volume, and which protocols are involved. You go from guessing to acting in seconds instead of manually analyzing traffic.
Retain customers
Hosting customers leave after downtime. When you can detect and mitigate attacks in seconds and show customers exactly what happened, they stay. Visibility and fast response are competitive advantages.
Traffic visibility
Even without attacks, Flowtriq gives you real-time traffic analytics: bandwidth utilization, PPS, protocol breakdown, and top talkers. Useful for capacity planning and spotting anomalies early.
