The LeanIT Approach

* Overall Increase: The number of Distributed Denial-of-Service (DDoS) attacks in Europe has exhibited a substantial upward trend. The Link11 European Cyber Report 2025 reported a 137% increase in DDoS attacks on their network compared to the preceding year.

* 2024 Trends:

* In the first quarter of 2024, approximately 2,200 DDoS attacks occurred globally per hour.

* HTTP DDoS attacks surged by 93% year-over-year, while network layer DDoS attacks increased by 28% year-over-year.

* Greece experienced 10,251 DDoS attacks during the first half of 2024.

* The largest attack bandwidth recorded was 303.53 Gbps.

* The average attack duration was 20.52 minutes.

* The establishment of the National Cybersecurity Authority (NCSA) in 2024 (Law 5086/2024) and the implementation of the NIS2 Directive in November 2024 underscore Greece’s heightened emphasis on fortifying its cyber defenses against threats such as DDoS.

In the Current Interconnected Global Landscape, our networks serve as the foundational infrastructure for virtually every aspect of human endeavor, encompassing critical infrastructure, financial transactions, communication systems, and entertainment platforms.

This profound reliance renders these networks primary targets for malicious entities, with Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks emerging as some of the most profoundly disruptive threats. Consequently, the prevention of these attacks is not merely a Technical Consideration: It is an Indispensable Prerequisite for Preserving Digital Society Stability, Security, and Operational Integrity.

The consequences of a successful Distributed Denial of Service (DoS) attack can be profoundly detrimental. By inundating a network, service, or server with an overwhelming volume of traffic, legitimate users are systematically denied access to essential resources. For commercial enterprises, this can result in substantial financial losses attributable to forfeited revenue, reputational damage, and the expenditures associated with recovery efforts. The sheer magnitude and advanced sophistication characteristic of contemporary DDoS attacks, frequently employing expansive botnets comprising compromised devices, make their mitigation exceptionally challenging without the implementation of robust preventative measures.

Effective DoS prevention strategies are inherently multi-layered, integrating both proactive and reactive methodologies. OpenText, represented by LeanIT, offers a comprehensive suite of cybersecurity solutions designed to prevent and mitigate the effects of DoS attacks. Their “Cybersecurity Cloud” portfolio includes offerings such as OpenText™ Core Threat Detection and Response and OpenText™ Network Detection & Response, which leverage artificial intelligence.

We, at LeanIT, are dedicated to providing enterprise-scale cybersecurity solutions with the utmost professionalism safeguarding your  business continuity.
