It was a perfectly ordinary morning. Roland Hambach, CEO of ene’t GmbH, was sitting at breakfast scrolling through his emails. Then came the first one with the subject line “DDoS Attack.” Then the second. Then the third. His first instinct: spam, delete. But then the IT department sounded the alarm at the same time. What followed was […]

Link11 has completely rebuilt its Layer 3/4 DDoS mitigation solution from the ground up. The Next-gen Network DDoS Protection combines proactive protection built for the AI era, and behavior-based detection with full IPv4 […]

DDoS attacks are rapidly growing in intensity and precision. They are now shorter, more targeted, and increasingly AI-generated. Link11 Network DDoS Protection has always been a strong and reliable standard for organizations looking to secure their network infrastructure. But the demands of modern enterprise networks have changed. Attackers are continuously refining their strategies. And the last thing your team deserves is the pressure to constantly recalibrate when an attack is underway. Therefore, in direct response to the […]

A two-stage DDoS attack with a bandwidth of over one terabit, targeting login, download, and admin sections, shows that modern attackers test systems during an attack as well as beforehand. There were two waves of attacks, separated by a ten-hour break. In total, over 335 million requests were sent. These included targeted attempts to log […]

In our latest Cyber Insight report, we analyze a politically motivated DDoS attack on a defense contractor. This was a Layer 7 attack, rather than a classic volumetric flood at the network level: it involved targeted pressure on the application layer. Each request must be evaluated by the WAF, involving rate limiting, session tracking, and […]

Not all attacks are spectacular. Some are rather inconspicuous, without reaching record levels of bandwidth or packet volume. This was the case with the following DDoS attack: At first glance, it seemed rather unspectacular, as the volume was around 3 million requests. Compared to large-scale DDoS campaigns, this is not an exceptional figure. Nevertheless, it is worth taking a closer look […]

When an enterprise becomes the target of a Distributed Denial of Service (DDoS) attack, the first action is often to block malicious traffic as quickly and rigorously as possible. But what happens when the mitigation measures overshoot the mark and lock out the very people you actually want to serve? When Protection Becomes an Obstacle: […]

Not all DDoS attacks have the same objective. Some are designed simply to overload, while others are intended to conceal something more nefarious. A massive increase in requests immediately raises red flags in every SOC. However, when millions of requests flood the infrastructure in a short period, standard diagnosis often falls short. At first glance, the case seems clear: a classic […]

In IT security, the following principle often applies: introduce a new tool for every new problem. As a result, many companies have developed a digital patchwork quilt over time. Endpoint protection here, firewalls there, identity management, DDoS protection, WAF, bot management, and API security—everything was purchased, configured, and operated individually. On paper, this looks like seamless coverage. In operational reality, however, […]

Web applications are the backbone of modern businesses. They serve as sales platforms, customer interfaces, and process engines. There is no question that this infrastructure must be protected. But in an IT landscape that is rapidly evolving toward APIs and microservices, one thing remains constant: standing still means risk. In light of this, is the classic protection approach still sufficient? […]

Some DDoS attacks are loud. Others are large. And still others are one thing above all else: widespread. A recent incident in the Link11 network shows how effective so-called carpet bombing can be. Within just two minutes, not a single server but an entire “/20 network” with more than 4,000 IP addresses was attacked. What at first glance appears […]
