Hostealo Shield · Madrid

What the node does when an attack hits

In slow motion: from the network edge to your server. The attack is recognised, the filter is applied and only clean traffic reaches your IP, with no tickets and no manual intervention.

Universal

Auto-discovery in all DCs

The system observes traffic on your ports, identifies the protocol and automatically applies the right filter. You don't need to open tickets, you don't need to configure rules, you don't need to know what A2S spoofing or RakNet flood is.

  1. 1
    Your service is provisioned

    VPS or dedicated server active at your IP in the chosen DC.

  2. 2
    The scrubbing observes traffic

    Heuristics + signatures over the first connection window.

  3. 3
    The right filter is applied

    Counter-Strike, Minecraft, FiveM, RakNet, OpenVPN… or generic L4 if none matches.

  4. 4
    Fine-tuning during an attack

    The NOC monitors 24/7 and tightens rules in real time when a sustained attack warrants it.

Filter catalog per datacenter

Each DC runs a different stack. Madrid (Hostealo Shield, in-house) carries the broadest catalog. EU (PletX / W&D Shield) covers the main presets plus a Custom filter where you define your own TCP values.

New York runs Basic Anti-DDoS (generic volumetric protection, no public catalog of per-application filters).

Madrid only

Advanced panel. Hostealo Shield

Because it's our own system, in Madrid we expose direct control over the scrubbing behavior per IP. Useful for customers with mixed traffic, persistent attacks or specific geo-filtering needs.

Per-IP rules

Drop by default, asymmetric or symmetric. Configure traffic behaviour for each IP in the block.

Custom filters

Create your own L4 rules over TCP/UDP when none of the presets covers your case.

ASN or country block/whitelist

Filter traffic by geographical origin or whole autonomous system. Useful to contain waves from specific regions.

IP lists

Whitelist or blacklist specific IPs or whole ranges, managed from the panel.

For external networks

IP Transit with Anti-DDoS

Operate your own AS? We become your upstream BGP with scrubbing applied to all incoming traffic. Announce your prefix through AS215691 and your network, as a downstream customer, only receives clean traffic.

  • Announce your IPv4 prefix with AS215691 as your upstream BGP
  • Hostealo Shield applied to all incoming traffic
  • ASN / country blocking and IP lists managed by you
  • Managed LOA + RPKI, valid if you re-announce to your own BGP customers
  • Compatible whether or not you have your own LIR

Frequently asked questions

What a sysadmin or CTO actually asks before trusting their network to an Anti-DDoS: coverage, mitigation latency, visibility, AI integrations and what happens with false positives. Yours missing? Drop us a line.

We cover the main vectors at L3 (network) and L4 (transport): SYN flood, UDP flood, ICMP flood, amplification (DNS, NTP, memcached, SSDP), reflection, fragmentation, spoofed IP, ACK flood and TCP reflect. Profiles are applied per application (gaming UDP, voice/VoIP, web, infra, VPN). In Madrid the catalog is extended with 40+ filters manageable from the panel.

No, we cover L3/L4 only. L7 attacks (HTTP flood, Slowloris, bots, scraping) are mitigated server-side: with a WAF, a CDN like Cloudflare in front, or rules in your own nginx/HAProxy. We focus on what happens before the packet reaches your server (network and transport). If you need full L7 coverage, combine it with a WAF/CDN layer on top.

Madrid: our own Hostealo Shield with +200 Gbps capacity. Eygelshoven (NL): PletX with +1 Tbps. Mainhausen (DE): W&D Shield + PletX with +1 Tbps. New York: Basic Anti-DDoS (no specific figure published). Capacities are per DC, not theoretical sums: each datacenter has its own scrubbing infrastructure.

Automatic detection in under 1 second. The system analyses traffic continuously, detects the attack pattern and applies the right per-application filter without human intervention. Mitigation is always-on, you don't have to activate anything when the attack arrives — it's already in place from the first packet.

Per-application profiles are applied automatically via auto-discovery: the system detects the traffic type (gaming, web, voice, VPN, etc.) and applies the corresponding filter without you touching anything. A first human review of your profile is always recommended and we coordinate it by ticket. If you contract IP Transit with GRE or BGP, the tunnel config and announcements from your side are on you.

Yes. We have XDP profiles specific to gaming. We cover the typical game-server protocols (custom UDP, Source engine, Steam protocol, Minecraft, RakNet, etc.) with filters that validate the protocol handshake and drop illegitimate traffic before reaching the server's port. That's why a game server on Hostealo stays up and lag-free under sustained floods.

They can happen (typical noise in any serious scrubbing system). If the system blocks legitimate traffic, tell us by ticket: our part of the scrubbing records the PCAP of the affected traffic and we analyse it with you to understand the pattern and adjust the rule. It's not a black box, we can see and change whatever's needed.

Yes, several options. Client panel with real-time attack visualisation, detected vectors and applied rules. REST API for direct management (add rules, query attacks, export logs). Built-in AI assistant in the panel that analyses attacks and suggests automatic profile adjustments. And an MCP server you can connect to ChatGPT, Claude or another LLM to manage Anti-DDoS from your own AI conversation.

L3/L4 Anti-DDoS is included at no cost on Hostealo VPS, dedicated servers and colocation. No franchise, no hidden add-ons, no paid tier. The only thing billed separately is IP Transit with Anti-DDoS: for external networks (not hosted at Hostealo) or services under constant attack that need reserved scrubbing capacity above what's included.

Service focused on customers with their own external network (their /24 IPv4 and ASN) who want to protect their traffic behind our scrubbing. Connection to our stack is via GRE, direct tunnel or BGP depending on the case. Price depends on traffic volume, reserved scrubbing capacity and connection model, so it's quoted case by case. Contact us for a concrete proposal.

Yes, through IP Transit with Anti-DDoS. Your /24 is announced behind our AS, traffic enters through our scrubbing and exits clean toward your origin, which can live in any datacenter (another provider, your own on-prem, multi-cloud, etc.). The connection from us to your origin is via GRE or BGP tunnel as you prefer.

The Madrid advanced panel (only available on Hostealo Shield, our in-house system) adds: per-IP rule definition, blocking by ASN or country, creation of custom XDP filters for specific cases and maintenance of IP lists (whitelist, blacklist). In the other DCs scrubbing is automatic without these advanced options, because mitigation is operated by the DC provider (PletX or W&D).

L3/L4 Anti-DDoS included, no tickets, no extras

Every Hostealo VPS, dedicated server or colocation includes L3/L4 Anti-DDoS protection from minute one, at no extra cost and no paperwork.
