Introduction: A Silent Shift in Cybersecurity Priorities
Cybersecurity has long revolved around protecting endpoints such as laptops, desktops, and servers. For years, these devices were considered the frontline of defense and the primary targets for attackers. But a new reality is emerging, one that quietly shifts the battlefield away from traditional systems into a far more complex and less visible layer of enterprise infrastructure.
Recent findings reveal that network infrastructure is now the most vulnerable part of modern organizations. This change is not gradual. It is rapid, disruptive, and deeply concerning. As businesses continue to expand their digital ecosystems with connected devices, the attack surface grows in ways that many security strategies are not yet equipped to handle.
Summary: A Rapidly Evolving Threat Landscape
Forescout’s latest 2026 report highlights a dramatic transformation in enterprise cyber risk, driven by the explosion of connected devices across IT, operational technology, IoT, and medical environments. The data, drawn from millions of assets, shows that the traditional focus on endpoints is no longer sufficient to understand or mitigate risk.
One of the most striking findings is that 75 percent of the riskiest device types identified today were not even considered high-risk just two years ago. This reflects how quickly the threat landscape is evolving, fueled by the adoption of specialized and often unmanaged devices. These devices are not always designed with security in mind, making them easy targets for attackers.
Network infrastructure has now taken center stage as the most critical risk category. Routers, in particular, have overtaken computers as the most vulnerable devices, accounting for about one-third of the most severe vulnerabilities. On average, routers and switches now carry nearly 32 vulnerabilities per device, a number that underscores their exposure.
The report also introduces 11 new high-risk device types that were previously overlooked. These include serial-to-IP converters, RFID readers, BACnet routers, and even medical image printers. Many of these devices exist outside traditional IT security frameworks, making them difficult to monitor, patch, or even detect within a network.
This shift reflects a broader trend where organizations deploy increasingly diverse and specialized technologies. While these tools improve efficiency and enable innovation, they also introduce new entry points for attackers. These entry points often lack proper security controls, making them ideal targets.
Another critical concern is the persistence of legacy systems. As older operating systems approach end-of-life, they continue to remain widely used across industries. Retail, healthcare, and financial services sectors are particularly affected, with a significant percentage of systems still running outdated software. These systems are often unsupported, leaving known vulnerabilities unpatched.
Beyond devices, protocol usage is also contributing to increased risk. Secure Shell (SSH) has become one of the most widely used protocols, while insecure protocols like Telnet are seeing a resurgence. Despite lacking encryption, Telnet continues to be used in sectors like manufacturing and finance, exposing sensitive data to interception.
Attackers are increasingly exploiting devices that act as bridges between different environments. For example, routers and IP cameras are now being used as entry points for ransomware attacks. Once inside, attackers can move laterally across networks, transitioning from IT systems into operational or medical environments with alarming ease.
Overall, the report paints a clear picture: risk is no longer concentrated in traditional endpoints. Instead, it is distributed across a fragmented ecosystem of connected devices, many of which are poorly secured and largely invisible to standard defenses.
What Undercode Say: The Real Problem Is Visibility, Not Just Vulnerability
The Illusion of Endpoint Security
Organizations have spent years investing heavily in endpoint protection platforms, antivirus solutions, and user-focused security training. While these measures remain important, they create a dangerous illusion that securing endpoints is enough. The reality is that attackers have simply shifted their focus to weaker, less monitored areas of the network.
The Rise of “Invisible” Devices
The most dangerous devices today are not the obvious ones. They are the overlooked systems quietly operating in the background. Printers, routers, IP cameras, and industrial controllers often escape strict security oversight. These devices rarely receive timely updates, and many still rely on default credentials or outdated firmware.
This invisibility creates the perfect conditions for attackers. A device that is not monitored is a device that cannot be defended.
Lateral Movement Is the New Battlefield
Modern cyberattacks are no longer about breaking in. They are about moving undetected once access is gained. Network infrastructure plays a critical role in this phase. If an attacker compromises a router, they gain a strategic position inside the network, allowing them to bypass perimeter defenses and move freely between systems.
This is why containment has become more important than prevention alone. Once an attacker is inside, the ability to limit their movement can determine whether an incident becomes a minor breach or a full-scale disaster.
Legacy Systems: A Persistent Weak Point
The continued reliance on outdated operating systems is not just a technical issue. It is a business risk. Organizations often delay upgrades due to cost, compatibility concerns, or operational disruption. But this delay comes at a high price.
Legacy systems act as open doors for attackers. They are well-documented, widely understood, and often unsupported. In industries like healthcare and finance, where uptime is critical, these vulnerabilities become even more dangerous.
Protocols: The Overlooked Risk Layer
While much attention is given to devices, communication protocols are often ignored. The resurgence of insecure protocols like Telnet is a clear sign that convenience still outweighs security in many environments. Without encryption, these protocols expose credentials and data to anyone capable of intercepting traffic.
This is not just a technical oversight. It reflects a deeper issue in how organizations prioritize security versus usability.
The Convergence of IT, OT, and IoT
One of the most significant challenges today is the convergence of different technological domains. IT systems are now deeply interconnected with operational technology and IoT devices. This integration creates efficiency but also amplifies risk.
An attack that begins in a simple IoT device can quickly escalate into critical infrastructure. The boundaries between systems are disappearing, and with them, the traditional security models that relied on segmentation.
Security Must Become Device-Agnostic
The future of cybersecurity lies in treating every connected device as a potential risk. It no longer matters whether a device is a laptop, a router, or a medical printer. If it is connected, it must be visible, monitored, and secured.
Organizations need to adopt a device-agnostic approach that focuses on behavior, communication patterns, and risk exposure rather than device type.
From Prevention to Continuous Control
The shift in risk demands a shift in strategy. Security can no longer rely solely on preventing breaches. It must focus on continuous monitoring, rapid detection, and effective containment.
This means investing in technologies that provide real-time visibility across all connected assets, not just traditional endpoints. It also requires rethinking network architecture to limit lateral movement and isolate compromised systems quickly.
Fact Checker Results
✅ Network infrastructure has overtaken endpoints as the primary risk category according to the report
✅ 75 percent of high-risk device types are newly identified within the past two years
❌ Many organizations are still not prioritizing non-traditional devices despite growing evidence of risk
Prediction
The Network Will Become the New Security Perimeter 🔐
As endpoints lose their central role, network-level security will define the next generation of defense strategies. Organizations will invest more in segmentation, zero trust architectures, and real-time monitoring.
IoT and OT Attacks Will Surge ⚠️
Attackers will increasingly target IoT and operational devices due to their weak security posture. Industries relying on these technologies will face a growing number of sophisticated attacks.
Legacy Systems Will Trigger Major Breaches 🚨
Unless aggressively phased out, outdated systems will be at the center of future large-scale cyber incidents, particularly in critical sectors like healthcare and finance.
