Service overview

DDoS Protection Services

A distributed denial-of-service attack does not need to breach anything to cost you money. It only needs to make your service unusable for long enough that customers give up, orders fail and support queues fill. Attacks range from high-volume network floods that exhaust bandwidth to quiet application-layer requests that look almost identical to real users, and the two are rarely defended by the same control.

Our DDoS protection service is for organisations that depend on public websites, APIs, portals, payment paths and network services being reachable. We help teams understand what is genuinely exposed, choose between always-on and on-demand mitigation, close the routes that let attack traffic bypass protection, and agree the thresholds, contacts and steps that turn a plan into a response. The engagement is scoped around your existing hosting, CDN, DNS and transit providers rather than pushing a particular vendor.

Service details

DDoS protection planning built around the services that must stay online

A DDoS protection service works best when it is designed around the way your business actually serves traffic. We review public hostnames, DNS, CDN and edge routing, origin exposure, upstream transit, API endpoints and the customer journeys that carry revenue, so mitigation defends availability without adding avoidable latency or dropping legitimate visitors.

We help you choose between always-on and on-demand mitigation, confirm what your hosting, CDN or transit provider will absorb, close the routes that bypass it and write the response plan your team follows when traffic turns hostile. We do not operate a scrubbing network ourselves. Mitigation capacity comes from your providers, and our work is making sure it sits in the right place and that someone knows how to use it.

Capacity alone does not make a business resilient. Mitigation has to be routed correctly, activated quickly, tested before it matters and owned by named people. That is why this service concentrates on traffic paths, activation decisions, alert thresholds, escalation contacts and the operational process behind the protection.

DDoS protection areas we help you plan

Useful DDoS protection is more than a large scrubbing capacity figure on a datasheet. It gives your team a defined traffic path, a realistic view of what can be absorbed, and an agreed way to act when availability starts to degrade.

Volumetric and network-layer attacks

High-volume floods aim to exhaust bandwidth, connection tables or upstream capacity before traffic ever reaches your application. We review the transit and edge capacity available to you, how UDP, SYN, amplification and reflection traffic would be absorbed, and whether mitigation sits close enough to the source to matter. Where the network path is provider-controlled, we document what the provider commits to and what remains your responsibility.

Application-layer and protocol attacks

Layer 7 attacks are smaller, cheaper to run and much harder to separate from real customers. Slow requests, repeated expensive queries, search and cart abuse, login floods and API hammering can degrade a service long before bandwidth is saturated. We look at rate controls, caching, request costs, challenge options and the endpoints most likely to be targeted, so mitigation can be tightened around them without harming normal use.

Origin exposure and activation readiness

Mitigation only works if attack traffic cannot walk around it. We map DNS records, historical IP exposure, mail and staging hosts, direct-to-origin routes and any addresses that would let an attacker bypass the edge. Alongside that we agree how mitigation is turned on, who is authorised to trigger it, what the expected time to mitigate is, and how the change is communicated while a service is degraded.

What we review

A focused DDoS scope before mitigation is chosen.

Before recommending a provider, a routing method or a spend, we build a practical picture of what must stay available, what would break first, and how quickly protection can realistically be brought into effect.

Critical services and impact tolerance

We identify the websites, APIs, portals, payment paths and network services where downtime carries real cost, and how long each can be degraded before the impact becomes serious. This shapes whether always-on mitigation is justified, or whether an on-demand arrangement with a clear activation trigger is proportionate.

Traffic path, providers and origin exposure

We map how visitors reach your services today across DNS, CDN, load balancers, reverse proxies, transit providers and hosting origin. We then look for the routes that bypass protection, including old DNS records, direct IP access, subdomains, mail hosts and staging systems that quietly point at production infrastructure.

Detection, thresholds and ownership

We review the monitoring that would tell you an attack has started, the thresholds that should raise an alert, who is contacted out of hours, which provider tickets need to be raised, and what evidence should be preserved for the post-incident review and any regulatory or customer reporting.

Scope and quote

Start with the right scope.

Tell us which websites, APIs or network services must stay available, how traffic reaches them today, and which hosting, CDN, DNS or mitigation providers you already use. We will confirm the proposed scope, provider responsibilities, deliverables, availability and pricing before work begins.

What a DDoS protection engagement can include

  • Critical service, hostname and availability dependency inventory
  • Traffic path, provider and origin exposure assessment
  • Volumetric and application-layer risk review
  • Mitigation options with always-on and on-demand comparison
  • Activation, routing and failover recommendations
  • Detection thresholds, alerting and escalation contacts
  • A written DDoS response runbook with named responsibilities
  • Quote-ready scope with technology, effort and responsibilities defined

DDOS READINESS

A DDoS plan that works under pressure, not just on paper.

Exposure mapping comes first and the response runbook last, so the decisions that matter during an attack are made before one starts.

  1. 01

    Exposure and dependency mapping

    We review public services, DNS records, CDN and edge routing, origin addresses, upstream providers and the business impact of losing each service before recommending any control.

  2. 02

    Mitigation design

    Provider options, always-on or on-demand activation, scrubbing routes, rate controls and application-layer protections are shaped around your traffic profile and tolerance for downtime rather than a generic package.

  3. 03

    Validation and thresholds

    We agree detection thresholds, alerting, activation triggers and expected time to mitigate, then walk through the routing and failover steps so they are understood before they are needed.

  4. 04

    Response handoff

    We document the runbook, escalation contacts, provider ticket routes, communication steps and post-incident review process, and confirm who owns each part when an event begins.

Frequently asked questions

Questions teams ask before committing to DDoS protection.

The DDoS failures that hurt are often not about capacity. They come from exposed origins, unclear activation authority and plans nobody has read. These answers explain how we keep the work practical.

What is the difference between volumetric and application-layer DDoS attacks?

Volumetric and network-layer attacks try to exhaust bandwidth, connection capacity or upstream links with very high traffic volumes, and are usually absorbed or diverted upstream. Application-layer attacks send far less traffic but target expensive operations such as search, login, cart or API calls, so they can degrade a service while bandwidth still looks normal. They generally need different controls, which is why both are reviewed separately. The CISA guide to understanding and responding to DDoS attacks uses the same split, describing volumetric, protocol and application-layer techniques as distinct problems.

Can attackers bypass DDoS protection?

Yes, if the origin remains reachable. Old DNS records, subdomains, mail hosts, staging systems and direct IP access can all expose addresses that sit behind the edge, and certificate transparency logs make forgotten hostnames easy to find. Part of the engagement is finding those routes and recommending how to close or restrict them so mitigation cannot simply be walked around.

Should we use always-on or on-demand mitigation?

It depends on how much downtime you can tolerate and how quickly you need protection to take effect. Always-on mitigation is continuously in the traffic path and responds immediately, but is typically more expensive and needs latency and configuration review. On-demand is activated when an attack is detected, which introduces a delay while routing changes take effect. We compare both against your services and impact tolerance.

How quickly can mitigation take effect?

That depends on the provider, the mitigation method and how activation is triggered. Always-on protection acts immediately, while on-demand routing changes take time to propagate. Rather than quoting a general figure, we confirm the expected time to mitigate with your provider, document it, and make sure detection and activation authority do not add avoidable delay.

Do we still need a WAF if we have DDoS protection?

Usually yes. DDoS protection focuses on keeping a service available under abnormal load. A web application firewall inspects HTTP requests for attack patterns and abuse. They overlap at the application layer, where rate limiting and request filtering help with both, but neither replaces the other. Some platforms combine the capabilities, and each control still needs its own configuration and owner.

Can mitigation be tested without causing an outage?

Yes, within limits agreed in advance. Depending on your provider, this can include configuration reviews, tabletop exercises using the response runbook, or a controlled test window coordinated with your team and the mitigation provider. We do not run live attack traffic against your systems without written authorisation and a clear rollback plan.
