DDoS Protection Services UK 2026: Costs, Providers & Business Protection Quick answer
DDoS protection services help keep websites, applications and network infrastructure available during distributed denial-of-service attacks by detecting malicious traffic and filtering or absorbing it before it overwhelms your systems.
Protection can be designed for:
websites and web applications
APIs
public IP addresses
DNS
data centres
internet-facing networks
cloud infrastructure
gaming and streaming platforms
Some website-level DDoS protection is available at little or no additional cost through services such as Cloudflare, while business-grade network protection, scrubbing services and enterprise DDoS mitigation are normally priced individually.

Key Takeaways
DDoS attacks attempt to make websites, applications or networks unavailable by overwhelming them with malicious traffic.
Protection needs to match the target: website, application, DNS, IP address or entire network.
Website DDoS protection can be inexpensive; dedicated network protection is usually bespoke.
Cloudflare currently includes unmetered website DDoS protection even on its free application plan.
Cloudflare Magic Transit protects network infrastructure and advertises mitigation of most attacks in under three seconds.
Imperva advertises a three-second mitigation SLA for Layer 3 and Layer 4 attacks.
Akamai Prolexic offers always-on or on-demand protection for cloud, on-premises and hybrid infrastructure.
DDoS protection is not the same as a firewall or WAF, although these technologies are often combined.
Businesses that depend heavily on online services should compare both attack protection and network resilience.
What is DDoS protection? A Distributed Denial-of-Service attack uses many systems or sources to generate excessive traffic or requests towards a target, and the aim is usually to exhaust:
bandwidth
server resources
connection tables
application capacity
until legitimate customers or staff can no longer reach the service.
DDoS protection sits between the attacker and the target and attempts to distinguish legitimate traffic from malicious traffic.
Depending on the service, unwanted traffic may be:
blocked
rate-limited
challenged
diverted
scrubbed through a mitigation network
before clean traffic is forwarded to your systems.
How much does DDoS protection cost? There is no useful single UK average because the products vary enormously.
A small company protecting one website has very different requirements from a business protecting an entire IP network or data centre.
A practical comparison is:
Type of protection Typical pricing approach
Basic website DDoS protection
Free or bundled
SME website + WAF protection
£15–£200+/month equivalent
Advanced application protection
Subscription or bespoke
Network DDoS protection
Bespoke
Always-on scrubbing

Benefits of DDoS Protection
DDoS protection services ensure that your business website and applications remain available, even during an attack, by filtering out malicious traffic. Advanced DDoS protection services offer real-time traffic monitoring, identifying unusual patterns that may indicate an attack(so you can respond immediately to threats). Modern DDoS protection solutions automatically detect and mitigate attacks. DDoS protection services can scale to meet growing demands. Many DDoS protection services come integrated with other security tools (such as firewalls and threat detection systems, to provide comprehensive network protection).
Types of DDoS Attacks DDoS attacks are commonly grouped into three broad categories.
Volumetric attacks
These attempt to consume available bandwidth by sending extremely large amounts of traffic.
Examples include:
UDP floods
DNS amplification
NTP amplification
Protocol attacks
These target weaknesses or limits in network and transport protocols – examples include:
SYN floods
fragmented packet attacks
state-exhaustion attacks
Application-layer attacks
These target applications rather than simply bandwidth.
Examples include:
HTTP floods
repeated expensive application requests
API request floods
This distinction matters because one type of mitigation may not protect against all three layers.
What should you ask a provider? Ask:
What exactly will be protected?
Do you protect Layer 3, 4 and 7 attacks?
Is protection always-on or on-demand?
What is the mitigation SLA?
How much network capacity is available?
How do you protect DNS?
Is WAF included?
Do you protect APIs?
Do you support non-HTTP applications?
How is traffic routed during an attack?
Is there an attack-size surcharge?
Is support available 24/7?
Is configuration managed for us?
What reporting is included?
Can the service protect cloud and on-premises infrastructure?
What happens if our primary connection fails?
DDoS protection and resilience DDoS mitigation is only one part of availability and your business might also need:
multiple internet connections
diverse routes
backup broadband
redundant firewalls
resilient DNS
multi-region hosting
disaster recovery
Final verdict DDoS protection is most valuable when downtime directly affects:
revenue
customers
operations
contractual SLAs
public services
For a standard business website, inexpensive or bundled protection may be enough.
For:
ecommerce
SaaS
gaming
data centres
public APIs
enterprise networks
dedicated Layer 3/4/7 protection becomes much more important – the key is to compare the service against what an attack could actually take offline.

DDoS protection FAQs What does DDoS stand for?
DDoS stands for Distributed Denial of Service.
What does a DDoS attack do?
It attempts to make a service unavailable by overwhelming its bandwidth, infrastructure or application resources with traffic or requests.
How much does DDoS protection cost?
Website protection can be free or bundled with web-security services. Advanced application, network and enterprise DDoS protection is often priced individually.
Is Cloudflare DDoS protection free?
Cloudflare currently includes unmetered website DDoS protection on its Free plan as well as paid application plans.
Does Cloudflare protect whole networks?
Yes. Cloudflare Magic Transit protects network infrastructure and IP ranges, but it uses bespoke annual pricing rather than the normal website-plan pricing.
Is a firewall enough to stop DDoS?
Not necessarily. Large attacks can overwhelm internet bandwidth before traffic even reaches the firewall.
What is DDoS scrubbing?
Scrubbing routes traffic through specialist infrastructure that filters malicious traffic before forwarding legitimate traffic to the destination.
What is an always-on DDoS service?
Traffic continuously passes through or is protected by the mitigation platform, allowing attacks to be handled without first switching traffic to another route.
What is on-demand DDoS protection?
Mitigation is activated when an attack is detected rather than running continuously.
What is a Layer 7 DDoS attack?
It targets the application layer, often by generating large numbers of apparently legitimate HTTP or API requests.
Is a SYN flood a volumetric attack?
A SYN flood is generally classified as a protocol/state-exhaustion attack, rather than simply a volumetric attack.
Is SQL injection a DDoS attack?
No. SQL injection is an application-security attack that attempts to manipulate database queries. It should not be listed as a type of DDoS attack.
Can DDoS attacks affect APIs?
Yes. APIs can be targeted with Layer 7 request floods designed to exhaust application resources.
Does a leased line stop DDoS attacks?
No. A leased line gives dedicated connectivity but does not itself filter malicious traffic.
Can DDoS protection work with cloud infrastructure?
Yes. Modern services can protect public cloud, private cloud, data centres and hybrid environments.
Do small businesses need DDoS protection?
It depends on how important online availability is. A business that would lose significant revenue when its website goes offline has a stronger case than one with a simple informational site.
