Why Danish DDoS protection matters for your business

DDoS attacks (Distributed Denial of Service) are among the most widespread and damaging cyber threats facing businesses today. A single attack can cripple your website, online shop or API within seconds, with serious consequences. This article explains what DDoS attacks are, how they work and why Danish DDoS protection using Arbor technology is the best protection for your business.

What are DDoS attacks and how do they work?

A DDoS attack floods your server or network with traffic from many simultaneous sources, typically a botnet of thousands of compromised devices. The aim is to make your service unavailable to legitimate users by overloading server resources or the network connection.

There are several types of DDoS attack:

  • Volumetric attacks: Flood the network with enormous amounts of traffic (e.g. UDP floods, ICMP floods). Can reach hundreds of Gbps
  • Protocol attacks: Exploit weaknesses in network protocols (e.g. SYN floods, Ping of Death)
  • Application-layer attacks: Target specific applications with seemingly legitimate requests (e.g. HTTP floods)
  • Amplification attacks: Exploit open services such as DNS or Memcached to amplify attack traffic

Historical examples include the Mirai botnet (around 620 Gbps) and the 1.35 Tbps attack on GitHub. Attacks of this size can take entire services offline within seconds.

Financial and reputational consequences

The consequences of a DDoS attack extend far beyond the immediate downtime:

  • Direct revenue loss: E-commerce businesses can lose thousands of kroner per hour during downtime
  • Support and recovery costs: Incident response, log analysis and system recovery require significant resources
  • SLA penalties: Failure to meet uptime guarantees can trigger penalties
  • Reputational damage: Repeated interruptions undermine customer trust and can have lasting effects on conversion rates
  • Legal risks: A lack of evidence of operational reliability may lead to fines under the GDPR

How Arbor DDoS protection works

Arbor Networks (now NETSCOUT) is the world's leading provider of DDoS protection solutions. Its technology combines on-premises appliances and cloud-based scrubbing with global threat intelligence and machine-learning-driven anomaly detection.

The process has three steps:

  • Detection: Arbor continuously monitors network traffic through flow telemetry (NetFlow/IPFIX), identifying anomalous patterns using signature and statistical analysis
  • Redirection: When an attack is detected, traffic is automatically redirected via BGP to Arbor's scrubbing centres
  • Scrubbing: Scrubbing centres filter out malicious traffic while prioritising legitimate traffic and forwarding it to your server

As a result, large volumetric attacks, for example around 150 Gbps, are neutralised without noticeable downtime for your users.

Benefits of Danish DDoS protection

Choosing a Danish provider with local Arbor protection instead of international solutions has concrete advantages:

  • Lower latency: Local scrubbing avoids routing traffic through distant data centres, minimising delay
  • Faster response: Local teams can activate tailored mitigation rules within seconds
  • GDPR compliance: Traffic data is processed within the EU and does not leave Denmark
  • Danish support: Direct contact with Danish engineers who understand your business and speak your language
  • Adapted to Danish conditions: Configuration can address sector-specific requirements in finance, healthcare and e-commerce

Proactive monitoring and real-time response

Effective DDoS protection is about more than reacting to attacks: it means detecting and neutralising them before they reach your infrastructure. At GITC, monitoring runs 24/7 with automated playbooks:

  • Automatic alerts for anomalous traffic patterns
  • BGP routing to scrubbers is activated automatically for large volumes
  • More granular filters are handled locally to minimise delay
  • HTTP-specific rules and session-aware rate limits for application attacks
  • Thresholds can be adjusted to your specific traffic profile

DDoS protection included in every GITC VPS plan

At GITC, Arbor DDoS protection is included free with all our VPS solutions. There is nothing extra to pay or configure: protection is integrated at the network layer and activated automatically.

Implementation is handled through our network setup: we announce your IP addresses through our BGP routes and configure automatic traffic redirection to Arbor scrubbing when thresholds are exceeded. You avoid extra complexity and can focus on your business.

The future of DDoS protection

DDoS attacks are becoming increasingly sophisticated. We see a clear trend towards:

  • Higher-bandwidth attacks driven by IoT botnets
  • Encrypted attacks requiring session inspection for detection
  • More targeted application-layer attacks
  • AI-driven attacks that adapt to protective measures

Arbor's solution is continuously updated with new threat intelligence from hundreds of networks worldwide, ensuring protection keeps pace with the latest attack methods.

Conclusion

DDoS protection is no longer a nice-to-have: it is essential for every business with an online presence. GITC VPS hosting includes free Arbor DDoS protection: local scrubbing, 24/7 monitoring and automatic filters identify and neutralise malicious traffic within milliseconds.

As a GITC customer, you can stop worrying about DDoS attacks and focus on what really matters: your business and your customers.
