Zayo's 2026 Cybersecurity Analysis Report reveals an alarming increase in cyberattacks targeting the manufacturing sector. Specifically, Distributed Denial of Service (DDoS) attacks are on the rise in both scale and targeted focus. While these attacks are a niche form of data breach, they are increasingly being weaponized by threat actors against industry.

π€ What is a DDoS Attack?
Simply put, a DDoS attack is a malicious attempt to disrupt a website or network by overwhelming it with a flood of traffic from numerous (and often compromised) sources. These attacks, using thousands of "zombie" devices instead of a single computer, render servers unavailable to legitimate users.

π Why is the Manufacturing Sector a Major Target?
According to Zayo's report, attackers are now moving beyond telecommunications networks to directly target businesses and critical organizations. This analysis, based on global traffic data from the past year, shows that while attack volume remains slightly below the record levels of 2024, attack frequency remains consistently high. This signals that DDoS has become a defining characteristic of today's threat landscape.
Max Clauson, Zayo's Senior Vice President of Network Connectivity, attributes this increase to the rise of artificial intelligence (AI), Internet of Things (IoT) devices, and rented botnets. According to Clauson, "This has ushered us into a new era where DDoS attacks are a persistent and highly destructive reality for all organizations, from manufacturers to retailers, schools to governments."

π‘ The Connectivity Revolution and Cybersecurity
Clauson notes that the increasing integration and connectivity of IT (Information Technology) and OT (Operational Technology) systems in the manufacturing sector expand the attack surface. Attackers know that disruptions in manufacturing can create a costly domino effect; network outages can impact production lines and expose sensitive intellectual property.
Another notable point in the report is that while the manufacturing sector accounts for a relatively small portion of the total attack volume, the average attack size is the largest, at 11.6 Gbps. This means that even short-term outages can have a significant operational impact.

π‘οΈ How Should Manufacturers Defend Themselves?
Clauson emphasizes that attacks are now faster and more intense, with nearly 90% ending in less than 10 minutes. Therefore, traditional, reactive approaches are insufficient.
[]Real-Time and Automated Mitigation: Manufacturers need real-time, automated mitigation systems that detect and respond to threats as they occur. This capability should be integrated into the network itself, not seen as a separate layer.
[]Proactive Security Solutions: Solutions such as DDoS protection, SD-WAN, and managed firewall services help manufacturers transition from reactive to proactive security.
- Visibility and Segmentation: As connected devices increase, understanding how traffic flows across the network is critical for quickly identifying and stopping attacks. Increasing cross-environment visibility and segmentation is essential.

π The Difference Between Attack Volume and Size
Attack volume refers to the overall level of activity during a specific period, while attack size measures the intensity of an individual event, typically in terms of bandwidth (such as gigabits per second). The research indicates that the average attack size has increased by approximately 70% compared to the previous year. This means that manufacturers need to pay more attention not only to the frequency of attacks but also to their size and intensity. Both metrics are critical for assessing risk and responding to attacks, especially in sectors like manufacturing where disruptions directly impact financial performance.
