Most engineers think… Most people picture DDoS protection as 'one appliance at the edge that blocks the flood'. That mental model breaks the moment an attack is bigger than your internet pipe. Radware DDoS protection is a portfolio : the DefensePro appliance does fast, low-latency behavioral detection and mitigation at the data-center edge; the Cloud DDoS Protection Service is a global Anycast scrubbing network that absorbs volumetric floods no single link can survive; Cloud Signaling is the automated bridge that pulls the cloud in within seconds; and it is all run from APSolute Vision with the 24x7 ERT behind it. The skill is knowing which layer solves which problem — and how the hybrid handoff stays gapless. ## ① Why one layer isn't enough — the pipe-vs-latency trade-off The single most important idea: no one layer wins alone . An on-prem appliance like DefensePro is fast — it scrubs at the edge in milliseconds with almost no added latency — but it can only clean what reaches it. If a volumetric flood is bigger than your internet pipe, the link is already saturated upstream of the box; the appliance reports 'mitigating' while users still see an outage. A pure cloud service solves the pipe problem with massive capacity, but routing all traffic through a distant scrubbing center adds latency and cost you may not want full-time. That tension — local speed versus cloud capacity — is exactly what Radware's portfolio resolves: detect locally, scrub globally, and hand off automatically when the pipe is threatened. Legend diagram title stage name what the stage does flow arrows & borders diagram canvas Figure 1 — The Radware DDoS loop — baseline, detect, mitigate, divert, return Local detection runs continuously; only when the pipe is threatened does traffic divert to the cloud and return clean. - The Radware DDoS loop — baseline, detect, mitigate, divert, return Baseline learn normal traffic Detect behavioral anomaly Mitigate Real-Time Signature Divert Cloud Signaling Return clean via DefensePipe Local detection runs continuously; only when the pipe is threatened does traffic divert to the cloud and return clean. Figure 2 — On-prem appliance vs cloud scrubbing Each layer solves a different half of the problem — which is why Radware pairs them in a hybrid model. On-prem appliance vs cloud scrubbing DefensePro (on-prem) Millisecond local mitigation Behavioral, no signatures Limited by your pipe size Best for L7 + speed Cloud DDoS (global) ~15 Tbps+ Anycast capacity Absorbs volumetric floods Adds latency / cost Best for huge volume Each layer solves a different half of the problem — which is why Radware pairs them in a hybrid model. Quick check · Q1 of 10 · Understand Why can an on-prem DDoS appliance still let an outage happen? a) A flood can saturate the internet pipe upstream of the appliance b) It is too slow to detect attacks c) It only works on encrypted traffic d) It needs a phone call to start Correct: a. DefensePro scrubs only what reaches it. If a volumetric flood exceeds your pipe, the link is saturated upstream of the box, so users see an outage even while it reports 'mitigating' — that is why you need cloud capacity too. 👉 So far: No single layer wins: an appliance is fast but pipe-limited, the cloud is huge but adds latency — so Radware detects locally and scrubs globally, handing off automatically. ## ② Meet the components — appliance, cloud, console and people Four pieces, one job each. DefensePro is the on-prem appliance (hardware or virtual DPVA): inline or out-of-path, it does patented behavioral, real-time detection with no pre-set signatures, covering network, DNS, low-and-slow, burst, Layer-7 / Web DDoS and encrypted attacks. The Cloud DDoS Protection Service is the muscle — a global, full-mesh Anycast scrubbing network (commonly cited at ~15 Tbps+) that absorbs the volume an appliance never could. ### The cockpit and the people APSolute Vision — delivered within Radware's Cyber Controller — is the single console to configure policy, monitor the attack lifecycle, run forensics and report across many DefensePro devices and sites, with SIEM/NMS/ticketing integration. Behind it sits the ERT (Emergency Response Team) : Radware's 24x7 SOC-backed experts who help mitigate live attacks, with emergency onboarding for customers already under fire and a strong time-to-detect/divert/mitigate SLA. Figure 3 — One portfolio, managed from one console DefensePro and the Cloud DDoS service are configured, monitored and reported from APSolute Vision, with the ERT on call.

Behavioral, real-time DDoS detection and mitigation at the edge — network, DNS, L7 and encrypted attacks. 📡 Cloud Signaling tap to flip The automated message from DefensePro to the Radware cloud asking it to divert and scrub when local capacity is threatened — the heart of hybrid. 🧬 Real-Time Signature (RTS) tap to flip A precise attack signature the BDoS engine auto-generates in roughly 18 seconds, blocking the attack while legitimate traffic flows. 🌐 DefensePipe tap to flip Radware's branded cloud diversion path: traffic is steered into it during a volumetric attack, scrubbed, and the clean traffic is returned. Name the layers, not just the box In an interview, separate the four pieces: DefensePro (fast local detection/mitigation), the Cloud DDoS service (volumetric scrubbing), Cloud Signaling/DefensePipe (the automated bridge), and APSolute Vision + ERT (manage and respond). Saying 'we have a Radware box' under-sells the whole portfolio. Quick check · Q2 of 10 · Remember Which component is the global scrubbing network that absorbs volumetric floods? a) DefensePro b) APSolute Vision c) The Cloud DDoS Protection Service d) The ERT Correct: c. The Cloud DDoS Protection Service is the global, full-mesh Anycast scrubbing network (~15 Tbps+). DefensePro is the on-prem appliance, APSolute Vision is the console, and the ERT is the human response team. 👉 So far: Four pieces: DefensePro (edge), Cloud DDoS service (volumetric muscle), APSolute Vision (the cockpit) and the ERT (24x7 people) — each with one job it does best. ## ③ How the hybrid model actually works — the gapless handoff Hybrid is where it clicks. DefensePro watches normal traffic and, the moment it sees an anomaly, its BDoS (Behavioral DoS) engine auto-generates a precise Real-Time Signature in roughly 18 seconds — blocking the attack while legitimate traffic flows, with no human in the loop. For everyday attacks that fit your pipe, the appliance alone finishes the job. When the inbound rate climbs toward link capacity, Cloud Signaling fires: DefensePro sends an automated message to the Radware cloud asking it to divert and scrub . Traffic is steered into DefensePipe (the branded cloud diversion path) via BGP or DNS, cleaned in the nearest scrubbing center, and the clean traffic is returned to you. No phone call, no manual reroute — the handoff happens in seconds, which is the whole point of 'hybrid'. Figure 4 — The hybrid handoff, step by step DefensePro mitigates locally until the pipe is threatened, then Cloud Signaling pulls in cloud scrubbing — gaplessly. The hybrid handoff, step by step Local detect + mitigate BDoS + Real-Time Signature in ~18s Threshold crossed Inbound nears link capacity Cloud Signaling + divert BGP/DNS steer into DefensePipe Scrub + return clean Anycast center cleans, sends back DefensePro mitigates locally until the pipe is threatened, then Cloud Signaling pulls in cloud scrubbing — gaplessly. 'The appliance handles everything' under-sell DefensePro cannot un-saturate a pipe that the flood already filled upstream. Without Cloud Signaling configured to divert before the link maxes out, a big volumetric attack still takes you down — always map appliance speed to cloud capacity via the signaling threshold. ### ▶ Watch a 40 Gbps flood get diverted and scrubbed in the cloud How a volumetric attack is handled end-to-end in a hybrid setup. Press Play for the healthy path, then Break it to see the classic failure. ① Detect DefensePro spots a UDP flood against the portal and BDoS auto-builds a Real-Time Signature to block it locally. ▼ ② Threshold Inbound traffic climbs toward link capacity; the appliance sees the pipe is about to saturate. ▼ ③ Signal + divert Cloud Signaling fires; traffic is steered into DefensePipe via BGP/DNS toward the nearest scrubbing center. ▼ ④ Scrub + return The Anycast cloud cleans the flood and returns legitimate traffic; the portal and DNS stay reachable. Press Play to step through the healthy hybrid path. Then press Break it . ▶ Play Next ▶ ⚠ Break it ↺ Reset Quick check · Q3 of 10 · Apply Inbound traffic is climbing toward your link's limit. In a hybrid setup, what should happen automatically? a) The appliance reboots b) APSolute Vision emails an admin only c) Cloud Signaling fires and traffic diverts into DefensePipe to be scrubbed d) The ERT is dispatched on-site Correct: c. When the inbound rate nears link capacity, DefensePro's Cloud Signaling sends an automated divert request; traffic is steered into DefensePipe (via BGP/DNS), scrubbed in the cloud and returned clean — a gapless handoff with no manual step. 👉 So far: Hybrid handoff: BDoS auto-builds a Real-Time Signature in ~18s; when the pipe is threatened, Cloud Signaling diverts traffic into DefensePipe, scrubs it and returns it clean — gaplessly. ## ④ Choosing your deployment — always-on, on-demand or hybrid Three cloud deployment modes, chosen by your constraints. Always-on permanently routes all traffic through the cloud — lowest risk, no on-prem box required, but it adds steady latency. On-demand only diverts when the pipe is threatened — the lowest-cost option, with a brief activation delay at the start of an attack. Hybrid keeps DefensePro doing instant local detection/mitigation and uses the cloud only for volumetric scrubbing via Cloud Signaling — best of both, but you must host and size the appliance. ### Pick by three questions How much latency can you tolerate? How big is your pipe versus the floods you expect? Can you host an appliance on-site? Latency-sensitive with a box you can host points to hybrid; no appliance and want simplicity points to always-on; cost-sensitive with rare attacks points to on-demand. The classic failure is running an appliance with Cloud Signaling left unconfigured — so a flood saturates the pipe and the cloud never gets the divert request. Figure 5 — Always-on vs on-demand vs hybrid Pick the mode by latency tolerance, pipe size and whether you can host an appliance. Always-on vs on-demand vs hybrid Always-on all traffic via cloud On-demand divert only on attack Hybrid on-prem + cloud signal Pick the mode by latency tolerance, pipe size and whether you can host an appliance. Karan Mehta at NetReach Broadband (Pune ISP) faces this During a 40 Gbps UDP flood the customer portal and DNS go unreachable for 2-3 minutes, even though DefensePro reports 'mitigating'. Likely cause The attack volume exceeds the upstream pipe — DefensePro is scrubbing correctly but the link itself is saturated upstream of the appliance, and cloud diversion is not kicking in. Diagnosis In APSolute Vision, open the DefensePro device's Security Monitoring / Attack dashboard and confirm RTS/BDoS is active with inbound rate pinned at link capacity; then under the device's Cloud / Defense Messaging settings, find the Cloud Signaling threshold unset or set too high, so no divert request is ever sent. APSolute Vision ▸ select DefensePro device ▸ Security Monitoring + Cloud / Defense Messaging (Cloud Signaling) Fix Enable Cloud Signaling, set the bandwidth threshold below the pipe limit (e.g. divert at ~70% of link), and confirm the cloud account and DefensePipe diversion (BGP or DNS) are provisioned. Verify Re-run a controlled volumetric test: in APSolute Vision watch the attack auto-divert to the scrubbing center, on-prem inbound rate drop, portal/DNS stay reachable, and clean traffic return via DefensePipe. Prove the divert, don't assume it Never trust 'Cloud Signaling is on' on faith. Run a controlled volumetric test and watch APSolute Vision show the attack divert to the scrubbing center, the on-prem inbound rate fall, and clean traffic return via DefensePipe. That single test answers whether your hybrid actually works. Quick check · Q4 of 10 · Analyze A cost-sensitive site rarely gets attacked and wants the cheapest cloud option. Which mode fits? a) Always-on b) On-demand c) Hybrid with always-on cloud d) No cloud at all Correct: b. On-demand diverts to the cloud only during an attack, so it is the lowest-cost mode — at the price of a brief activation delay. Always-on routes everything through the cloud full-time; hybrid keeps an on-prem appliance running. 👉 So far: Pick by latency, pipe size and appliance hosting: always-on (simplest), on-demand (cheapest), hybrid (best of both). The classic failure is leaving Cloud Signaling unconfigured. ### 🤖 Ask the AI Tutor Tap any question — instant, scoped to this lesson. No login, no waiting.

Tap Submit all answers at the end. Q5 · Remember Where does the DefensePro appliance primarily sit? a) In a cloud scrubbing center b) At the data-center edge / perimeter c) On the end-user laptop d) At the DNS registrar Correct: b. DefensePro is the on-prem appliance (hardware or virtual DPVA) deployed inline or out-of-path at the perimeter, doing fast local detection and mitigation. The cloud service lives in Radware's global scrubbing network. Q6 · Understand DefensePro detects attacks primarily by which method? a) Behavioral baselining plus auto-generated Real-Time Signatures b) Static signatures only c) A static IP blocklist d) Manual rules typed per attack Correct: a. DefensePro uses patented behavioral detection — it learns a normal-traffic baseline and, on an anomaly, its BDoS engine auto-builds a Real-Time Signature in ~18 seconds. It does not rely on pre-set signatures or manual rules. Q7 · Apply A 40 Gbps flood is overwhelming a 10 Gbps pipe. What actually saves the site? a) A bigger appliance CPU b) Diverting traffic to the cloud scrubbing network via Cloud Signaling c) Disabling SSL on the box d) Logging out of APSolute Vision Correct: b. Once a flood exceeds the pipe, no on-prem box can help — the link is saturated upstream. Cloud Signaling diverts traffic into DefensePipe so the global cloud absorbs the volume and returns clean traffic. Q8 · Analyze Why is the hybrid model called a 'gapless' handoff? a) Because a human approves each divert by phone b) Because the cloud is always scrubbing everything c) Because DefensePro reboots before diverting d) Because Cloud Signaling automatically pulls in cloud scrubbing in seconds when the pipe is threatened Correct: d. DefensePro mitigates locally and, the instant the link nears saturation, Cloud Signaling fires automatically and traffic diverts into DefensePipe — no phone call or manual reroute, so there is no protection gap during the handoff. Q9 · Evaluate A latency-sensitive bank can host an appliance and wants instant local mitigation plus cover for huge floods. Best deployment? a) Always-on cloud b) On-demand cloud only c) Hybrid (on-prem DefensePro + cloud via Cloud Signaling) d) No DDoS protection Correct: c. Hybrid keeps DefensePro doing millisecond local mitigation (great for latency) while Cloud Signaling brings in cloud capacity only for volumetric floods. Always-on adds steady latency; on-demand alone gives up the instant local layer. Q10 · Evaluate What is the most common reason a hybrid Radware setup still suffers an outage? a) Too many Real-Time Signatures b) The ERT was not phoned in time c) Cloud Signaling was left unconfigured, so no divert request is sent before the pipe saturates d) APSolute Vision was logged out Correct: c. If the Cloud Signaling threshold is unset or set above the pipe limit, DefensePro never asks the cloud to divert; the link saturates upstream and the cloud never engages — even while the appliance reports 'mitigating'. Set the threshold below link capacity. Submit all answers Try again Lesson complete — saved to your profile. Almost!

Then compare with the expert version. Compare with expert answer Expert version: Because no single layer wins. DefensePro detects and mitigates at the edge in milliseconds — perfect for speed and Layer-7 attacks — but it cannot un-saturate a pipe a volumetric flood has already filled upstream. The global Cloud DDoS service has the Anycast capacity to absorb that volume, and Cloud Signaling automatically diverts traffic into DefensePipe the moment the link is threatened, then returns it clean. You manage it all from APSolute Vision with the 24x7 ERT behind you, which is exactly why it is a portfolio — local speed, cloud scale, automatic handoff — not one box. ### 🗣 Teach a friend Best way to lock it in — explain it in one line to a teammate.
