Deploying Anti-DDoS Agent on the ISP Level — Flowtriq
ISPs sit at an interesting point in the DDoS problem. Every attack hitting a downstream customer crosses the provider’s network first. The ISP absorbs collateral bandwidth, deals with the support volume, and often takes the blame even when the attack originated somewhere else entirely. The standard toolkit has been upstream blackholing: nullroute the attacked IP, traffic stops, customer goes offline. The attack wins.
The 2026 State of DDoS report from Flowtriq puts some numbers around why this matters now more than before. Carpet-bombing attacks, which spread traffic across entire subnets rather than hitting a single IP, increased 180% in 2025. A /24 carpet-bomb at 500 Mbps per IP adds up to 127 Gbps of aggregate traffic, none of which necessarily trips per-IP detection thresholds. These attacks are specifically designed to defeat the kind of monitoring that ISPs typically have in place.
Flowtriq’s approach at the ISP level is per-node agents on customer infrastructure, feeding into a unified view across all monitored nodes. When an attack is detected, the escalation chain can include BGP FlowSpec rules pushed to your border routers automatically. FlowSpec lets you do surgical filtering: rate-limit UDP/53 from a specific source range, drop traffic matching a particular payload signature, or blackhole specific attack infrastructure without nullrouting the customer’s entire IP. Flowtriq users who deployed FlowSpec as an escalation tier saw a 73% reduction in bandwidth consumed by attacks that exceeded local mitigation capacity, according to the same report.
The practical setup for an ISP is a workspace per customer, with your NOC team having oversight across all of them. Customers can have read-only access to their own workspace, including their status page and incident history. When an attack hits, the customer knows what’s happening and can see mitigation is active without opening a support ticket.
For ISPs who want to offer DDoS protection as a managed product, the white label path at flowtriq.com/white-label handles the branding. You run it as your service, under your name, billed however your market supports. The underlying detection, BGP FlowSpec integration, and cloud scrubbing escalation is Flowtriq.
