DDoS Mitigation & Traffic Scrubbing

When the flood hits, you want engineers who’ve seen it before — and know exactly what to do.

DDoS Attacks Don’t Give You a Warning. Your Mitigation Strategy Should Be Ready Before They Do.

Distributed Denial of Service attacks have evolved far beyond the blunt volumetric floods of a decade ago. Today’s attacks are multi-vector, increasingly sophisticated, and often designed to bypass naive mitigation strategies while staying just below the threshold that triggers automated defences.

At AMROTS, we approach DDoS mitigation the way we approach everything else — as a network engineering problem, not a product sale. We design and implement mitigation architectures using BGP Blackholing, Remotely Triggered Black Hole routing (RTBH), Flowspec, and upstream scrubbing centre integration — giving you layered, intelligent defences that protect your infrastructure without taking your legitimate traffic down with it.

Because that’s the part most people forget: a mitigation strategy that kills your service is barely better than the attack itself

BGP Blackholing and RTBH for rapid, surgical traffic suppression at the routing layer

Flowspec policy design for granular, protocol-aware traffic filtering without full blackholing

Upstream scrubbing centre integration — diverting attack traffic before it reaches your network

Multi-vector attack detection covering volumetric, protocol, and application-layer attack types

Always-on and on-demand mitigation architectures tailored to your environment

Post-attack analysis and reporting — understanding what hit you and hardening against the next attempt

Know What You’re Defending Against

Not all DDoS attacks are the same — and a mitigation strategy built for one type can fail completely against another. Understanding the attack landscape is the first step to building a defence that actually holds.

Volumetric Attacks

The classic flood — UDP amplification, ICMP floods, DNS reflection. The goal is simple: saturate your uplink with more traffic than your infrastructure can handle. Measured in Gbps or Tbps, these are the attacks that make headlines and knock unprepared networks offline in seconds.

Protocol Attacks

SYN floods, fragmented packet attacks, and Smurf attacks target network infrastructure layer weaknesses — exhausting stateful devices like firewalls and load balancers rather than bandwidth. Smaller in volume but devastating to infrastructure that isn’t designed to handle them.

Application Layer Attacks

HTTP floods, Slowloris, and DNS query floods operate at Layer 7 — mimicking legitimate traffic patterns to evade detection while overwhelming application servers. These are the hardest to detect and the most damaging to web-facing services.

Multi-Vector Attacks

Increasingly, attackers combine multiple attack types simultaneously — launching a volumetric flood to trigger mitigation, then slipping application-layer attacks through the gap. Defending against these requires layered mitigation architecture, not a single solution.

Surgical Mitigation — Not a Kill Switch

Blackholing an attacked prefix keeps your network up but takes your service down. Good DDoS mitigation is about dropping attack traffic while keeping legitimate traffic flowing — and that requires engineering, not just automation.

Flowspec: The Precision Tool

BGP Flowspec lets us push granular traffic filtering rules to your upstream routers in real time — filtering by source IP, destination port, packet size, and protocol without touching your routing table. It's one of the most powerful DDoS mitigation tools available, and most networks aren't using it.

Defence Starts With Design

The best time to build your DDoS mitigation architecture is before an attack, not during one. We work with you to design layered defences that are ready to activate the moment anomalous traffic is detected.

Our approach

How We Build Your DDoS Defence.

Through experienced startup consultants who understand the isolated tasks necessary, a client can rely on a professional to manage a critical step in the early stages and focus on other items that need attention.

Threat Assessment & Architecture Design

Every DDoS mitigation engagement starts with understanding your threat profile. What are you protecting? What are your upstream transit relationships? Do you operate your own ASN? What's your current detection and response capability? The answers to these questions determine the right mitigation architecture — and there's no one-size-fits-all answer. We design solutions that fit your environment, your budget, and the realistic threat landscape you face.

Implementation & Integration

We implement your DDoS mitigation architecture end to end — configuring RTBH triggers, deploying Flowspec policies, integrating upstream scrubbing centre connectivity, and building the detection and alerting logic that ties it all together. Everything is documented, tested against simulated attack traffic where possible, and reviewed with your team before go-live.

Ongoing Monitoring & Response

A mitigation architecture is only as good as the people watching it. We provide ongoing monitoring for attack traffic anomalies, manage mitigation activations, and produce post-attack reports with root cause analysis and recommendations. After every significant attack, we review what happened, how the mitigation performed, and what we can do better next time.

Our DDoS Mitigation Process

The cost of designing a DDoS mitigation strategy is a fraction of the cost of an unmitigated attack. Let’s build your defence before you need it.

Threat Profile & Environment Assessment

We assess your current infrastructure, upstream transit relationships, ASN configuration, and existing detection capabilities — building a clear picture of your attack surface and the mitigation options available to you.

Mitigation Architecture Design

We design a layered mitigation architecture appropriate for your environment — RTBH, Flowspec, scrubbing centre integration, or a combination — with detection logic, activation procedures, and escalation runbooks documented and agreed before implementation.

Implementation & Testing

We implement the mitigation architecture, configure detection and alerting, integrate upstream scrubbing where applicable, and test the solution against simulated traffic scenarios. Nothing goes live without being validated.

Live Monitoring & Incident Response

With your mitigation architecture in place, we monitor for attack traffic continuously — activating mitigation, managing the response, and communicating with your team throughout any incident. Post-attack analysis and reporting are provided after every significant event.

Frequently Asked Questions

Some frequently asked questions about the service that you may have questions about

What types of DDoS attacks can you protect against?

We design mitigation strategies covering all three major attack categories — volumetric attacks (UDP floods, DNS/NTP amplification), protocol attacks (SYN floods, fragmented packets), and application-layer attacks (HTTP floods, DNS query floods). Multi-vector attacks that combine multiple types simultaneously require layered mitigation architecture, which is exactly what we build.

What is RTBH and how does it work?

Remotely Triggered Black Hole routing is a BGP-based technique that instructs your upstream routers to drop traffic destined for an attacked IP address before it reaches your network. It's fast, effective, and widely supported by transit providers — but it comes with a trade-off: the attacked IP goes dark along with the attack traffic. For many scenarios it's the right first response; for others, Flowspec or scrubbing centre diversion is a better fit.

What is Flowspec and when should I use it?

BGP Flowspec extends the routing protocol to carry traffic filtering rules — allowing you to drop or rate-limit traffic matching specific criteria (source IP, destination port, protocol, packet size) without full blackholing. It's a far more surgical tool than RTBH, keeping your service up while blocking attack traffic. Not all transit providers support it, which is one of the first things we check during our assessment.

Do you provide emergency response for active attacks?

Yes. If you are under active attack right now, call us immediately on +374 00 000 000. We will triage the situation, assess what options are available in your environment, and work to get mitigation in place as quickly as possible. Existing managed clients have priority response under their SLA.

Can you help us if we don't have our own ASN?

Yes — many DDoS mitigation options work at the provider level even without your own ASN. We'll assess what's available to you based on your hosting and transit arrangements and design the most effective mitigation strategy for your situation.

How long does it take to implement a DDoS mitigation architecture?

For straightforward RTBH and Flowspec implementations, we can typically have a baseline mitigation architecture in place within days. More complex deployments involving scrubbing centre integration and custom detection logic take longer to design and test properly — but the time invested upfront pays back many times over when an attack hits.
