Cloudflare and FastNetMon DDoS Protection for High Performance Network Security
In 2025, the DDoS record was broken seven times. Attacks grew 700% in volume year over year. FastNetMon detected one of the largest packet-rate floods ever recorded 1.5 billion packets per second across 11,000+ compromised networks. If your ISP’s bundled protection relies on a static bandwidth ceiling with no real-time visibility, you are flying blind against a threat that moves in milliseconds. As a FastNetMon partner, Axclusive deploys FastNetMon Advanced at our network edge, giving every customer access to the same high-performance DDoS detection platform trusted by ISPs and carriers worldwide.
Why You Need More Than a Bandwidth Ceiling
Standard ISP DDoS protection is typically a volumetric filter capped at roughly 10× your subscribed bandwidth. It has two critical blind spots:
No visibility. You cannot see what is hitting your network in real time. You only know you were attacked after the damage is done.
No intelligence. A static bandwidth cap cannot distinguish a 500 Mbps application-layer flood from a legitimate traffic spike. It either lets everything through or blocks everything.
No automation. When a volumetric event exceeds the cap, mitigation requires a manual support ticket. By the time a human responds, a 35-second burst attack has already finished.
No granularity. ISP filters cannot apply per-host or per-subnet thresholds. A targeted attack on one IP can trigger a blackhole that takes down your entire prefix.
The real gap
The biggest problem with standard ISP DDoS protection is not the bandwidth ceiling — it’s the lack of real-time detection and automated response. Without knowing exactly what is happening on your network, every mitigation decision is reactive, slow, and blunt.
How Axclusive Delivers FastNetMon Advanced
FastNetMon Advanced runs at the Axclusive network edge, continuously analysing every traffic flow that crosses your circuit. It is not an add-on bolted to the side — it is integrated into our routing infrastructure so that detection and response happen at wire speed.
Real-time traffic analysis
FastNetMon ingests NetFlow, sFlow, and IPFIX data from our edge routers, processing millions of flows per second. It builds a live baseline of your normal traffic patterns and flags deviations in sub-second timeframes before they escalate into full-scale attacks.
Per-host and per-subnet thresholds
Unlike blunt ISP-wide filters, FastNetMon lets us configure detection thresholds at the individual host or host-group level. This means a targeted attack on a single IP is identified and contained without triggering a network-wide blackhole that would affect your other services.
Automated mitigation via BGP
When an attack is confirmed, FastNetMon triggers automated mitigation through industry-standard BGP mechanisms:
BGP FlowSpec — surgical traffic filtering rules pushed to edge routers in real time, blocking only the malicious traffic patterns while legitimate users pass through unaffected.
RTBH (Remote Triggered Black Hole) — for massive volumetric events, affected prefixes are null-routed at the network edge to protect the broader infrastructure, with automatic withdrawal once the attack subsides.
Scrubbing centre diversion — FastNetMon can automatically redirect affected traffic to upstream scrubbing infrastructure (including Cloudflare Magic Transit) for deep cleaning before delivery back to your circuit.
Full traffic visibility and attack forensics Every detection event is logged with complete flow data: source IPs, protocols, packet sizes, rates, and duration. Your team gets real-time dashboards, historical attack analytics, and the data needed for post-incident reporting and compliance audits.
FastNetMon vs Standard ISP Protection At a Glance

| Mitigation options | Blackhole entire prefix | FlowSpec, RTBH, and scrubbing diversion |
| Visibility | Basic or no reporting | Real-time dashboards and full attack forensics |
| Automation | Manual ticket required | Fully automated detect, classify, mitigate, and recover |
| False positives | High, blunt filtering | Low, deterministic logic |
| Impact on legitimate traffic | Collateral blackholing | Surgical filtering of attack traffic only |
Why Customers Choose FastNetMon on Axclusive
See what is hitting your network in real time
Most businesses never see the attack. They see the outage. With FastNetMon on your Axclusive circuit, you get live visibility into every flow crossing your network edge. You know what is happening, when it starts, and exactly how it is being handled — before it becomes a business impact.
Surgical response, not a sledgehammer
Standard ISP protection has one move: blackhole the target. FastNetMon gives you a spectrum of responses — from FlowSpec rules that surgically filter only the attack pattern, to RTBH for extreme events, to automated diversion to cloud scrubbing. The right response is selected automatically based on the type and severity of the attack.
Protection tailored to your traffic profile
FastNetMon’s per-host thresholds mean your web server, your VPN gateway, and your mail server each have detection rules matched to their normal traffic patterns. A spike on your web server does not trigger a false alarm on your mail server. This precision dramatically reduces false positives and ensures legitimate traffic is never disrupted.
Managed service no expertise required on your side
Axclusive operates and maintains the FastNetMon infrastructure at our network edge. You do not need to deploy hardware, hire DDoS analysts, or learn BGP FlowSpec. We handle the configuration, threshold tuning, and 24/7 monitoring. You get the protection and the dashboards — we handle the engineering.
Predictable, competitive pricing
FastNetMon is delivered as a managed service bundled with your Axclusive circuit. No CapEx for on-premises detection appliances, no per-attack surcharges, no surprise overage bills. One predictable monthly cost for enterprise-grade DDoS detection and automated response.
Works perfectly alongside Cloudflare Magic Transit
For customers who want both real-time detection intelligence and Tbps-scale cloud scrubbing, FastNetMon integrates directly with Cloudflare Magic Transit — also available on Axclusive circuits. FastNetMon detects and classifies the attack; Cloudflare absorbs and scrubs it. Together, they form a complete defence stack from detection to mitigation.
Frequently Asked Questions
Can I add FastNetMon to my existing Axclusive circuit?
Yes. FastNetMon is available as a managed service add-on for all existing and new Axclusive DIA and IP Transit customers. Deployment is handled entirely by our engineering team.
Do I need to install anything on my side?
No. FastNetMon runs on the Axclusive network edge. Your existing infrastructure remains unchanged. You simply get access to the dashboards and alerts.
How is this different from the DDoS protection my ISP already includes?
ISP-bundled protection is a static bandwidth ceiling with no visibility and no automation. FastNetMon gives you real-time flow analysis, per-host thresholds, automated BGP-based mitigation, and full attack forensics. It is the difference between a locked door and a manned security operations centre.
Can FastNetMon work with other scrubbing providers?
Yes. FastNetMon supports automated diversion to multiple upstream scrubbing platforms via BGP, including Cloudflare Magic Transit, which is also available through Axclusive.
Is this suitable for smaller businesses?
Absolutely. Because Axclusive operates FastNetMon as a managed service, you do not need a dedicated security team. The platform scales from small single-server environments to large multi-subnet deployments.
