The fragmented management of printer fleets across supply chain, IT, and security departments often results in these devices remaining in their vulnerable factory-default states. This persistent oversight exists despite the fact that modern enterprises have reached a high level of maturity in defending primary endpoints like laptops and mobile servers. The current landscape of 2026 reveals a stark paradox: while billions are spent on advanced threat detection for workstations, a massive class of secondary endpoints remains almost entirely exposed to sophisticated cyber threats. These “forgotten” assets are not merely peripheral tools but are fully functional networked computers capable of storing vast amounts of data and maintaining high-level access to corporate directories. The lack of unified oversight means that a printer or an Internet of Things (IoT) sensor can often serve as an unmonitored bridge for attackers to bypass even the most expensive firewall installations. Consequently, securing this shadow infrastructure has become a primary objective for organizations that recognize the limitations of traditional perimeter-based defense. Moving toward a more resilient posture requires a fundamental shift in how secondary assets are classified, monitored, and integrated into the broader cybersecurity ecosystem of the modern digital enterprise.
Identifying the Cultural and Structural Barriers to IoT Security
Internal Fragmentation: The Organizational Ownership Gap
One of the most significant obstacles to securing the IoT environment is the “nonchalant and indifferent” attitude many enterprises maintain toward printer security. This indifference is often born out of organizational fragmentation, where the responsibility for these devices is split among disparate departments that rarely communicate on security strategy. The supply chain department typically handles procurement and Managed Print Services (MPS) contracts, focusing on cost and vendor reliability. Meanwhile, the IT department manages the network infrastructure, ensuring the devices are connected and functional, while the Information Security (InfoSec) team manages broader enterprise risk. Because no single entity “owns” the cybersecurity health of the printer fleet, these devices are frequently left in their factory-default states, with open ports and default passwords that act as an open invitation to malicious actors seeking an easy entry point into the internal network.
Beyond the administrative confusion, there is a persistent cultural belief that printers are low-risk, analog-adjacent machines rather than the sophisticated networked computers they actually are. This “just a printer” fallacy ignores the reality that modern multi-function printers possess administrator-level access to sensitive systems, including email servers, Lightweight Directory Access Protocol (LDAP) directories, and internal file servers. This high level of privilege, combined with the myth that a slow transition to paperless offices eliminates the need for security, leaves thousands of active devices unmonitored. While organizations focus on digital transformation, they often overlook the “ghost” hardware that remains on the network, providing a persistent and unpatched vulnerability. Securing these assets requires a unified governance model that bridges the gap between procurement, operations, and security to ensure every device is accounted for and hardened according to enterprise standards.
Strategic Limitations: Why Traditional Maintenance Fails
Many organizational leaders mistakenly assume that because their printer fleets are “managed” by an external provider, they are also “protected” from cyber threats. However, standard managed print services (MPS) focus almost exclusively on operational uptime, hardware maintenance, and toner replenishment. These providers are typically measured by Service Level Agreements (SLAs) related to mechanical performance rather than security compliance or vulnerability management. The primary goal of an MPS provider is to ensure that employees can print and scan without interruption, which often leads them to prioritize ease of access over restrictive security configurations. This operational focus creates a significant gap between hardware maintenance and actual cybersecurity defense, as the providers are not usually contracted to perform deep-dive security audits or continuous configuration monitoring.
Furthermore, traditional managed services are often not equipped with the specialized knowledge required to handle the continuous operationalization of cyber hygiene in a modern threat environment. While a technician might be adept at replacing a fuser or updating a printer driver, they are rarely trained to manage certificate lifecycles or machine identities across a mixed-vendor fleet. This disconnect means that even when security patches are released by manufacturers, they may not be applied in a timely manner across the entire enterprise. The sheer heterogeneity of large printer fleets—consisting of different brands, ages, and firmware capabilities—creates a management nightmare that standard maintenance programs cannot resolve. Without a specialized security layer, the “managed” fleet remains a collection of disparate vulnerabilities that can be exploited by automated AI tools designed to scan for unpatched IoT endpoints.
Developing New Protocols for Managed Cybersecurity
Operational Integrity: Transitioning to Managed Service Models
To effectively secure these assets, organizations must move toward an operational framework that assumes full responsibility for executing and maintaining security controls. This programmatic approach goes beyond simple monitoring and moves into a “done-for-you” model where a dedicated security team manages the entire lifecycle of the device. The foundation of such a program is the maintenance of an evergreen inventory, providing a real-time, accurate list of every device on the network, including new additions and those that have “vanished” due to decommissioning or technical failure. By establishing a “known good” baseline security configuration, the program can continuously monitor for “drift”—unauthorized or accidental changes to device settings that often occur during routine maintenance or power cycles.
The second critical component of this model is the systematic remediation of identified gaps. In a traditional IT environment, a security alert often just adds to the workload of an already overstretched staff, but a managed cybersecurity program takes ownership of the execution. This includes managing the rotation of credentials, overseeing machine identities through automated certificate management, and ensuring that all devices are running the latest firmware to mitigate known vulnerabilities. By providing rigorous governance and reporting, this model allows Information Security and Compliance teams to prove that security controls are active and effective without placing an additional operational burden on internal personnel. This shift from “alerting” to “executing” ensures that the security posture of the printer fleet is maintained with the same level of discipline as the company’s primary servers and workstations.
Future-Proofing the Fleet: AI Threats and Zero Trust
The urgency of securing IoT assets is further highlighted by the rapidly evolving threat landscape of 2026, where AI-enhanced attacks are making it easier for hackers to exploit unpatched devices at scale. Malicious actors now use automated tools to identify misconfigured printers and use them as persistent beachheads for lateral movement across the network. As enterprises shift toward Zero Trust architectures, the concept of “identity” must be pushed down to the machine level, requiring every connected device to prove its integrity before being allowed to communicate. This transition necessitates sophisticated certificate management and 802.1X authentication protocols—capabilities that many legacy printer fleets and IoT devices struggle to support without the intervention of an active, specialized management program.
Navigating this complex environment requires a highly structured approach to ensure that hardening measures do not disrupt essential business operations, particularly in critical sectors like healthcare where uptime is vital. Technical transitions, such as the move toward “driverless” printing through protocols like IPP and Mopria, are changing how devices interact with networks and introducing new security requirements that legacy devices may not meet. By focusing on security outcomes rather than just hardware status, specialized programs can manage the renewal of certificates and the application of patches across a diverse fleet of thousands of devices. This blueprint for printer security is already being expanded to other “forgotten” classes of hardware, such as networked cameras and environmental sensors, ensuring that every connected endpoint is governed, protected, and integrated into the enterprise’s defensive strategy.
Strategic Directions for Lasting Security
The industry recognized that the path forward required a transition from passive monitoring to a model of active, managed execution that addressed the specific nuances of IoT hardware. Organizations successfully reduced their attack surface by treating every networked printer not as a peripheral, but as a high-privilege workstation that demanded consistent cyber hygiene. Security leaders moved away from the assumption that standard maintenance contracts covered digital defense, and instead, they implemented specialized programs that automated the detection of configuration drift and the rotation of machine credentials. This proactive governance ensured that as the threat landscape evolved, the “forgotten” world of printers and sensors remained fortified against automated AI attacks.
Looking ahead, the most successful enterprises integrated their IoT security strategy directly into their broader Zero Trust frameworks to eliminate any remaining blind spots. They prioritized the implementation of machine identity and encrypted communication protocols across all legacy and modern devices, ensuring that every endpoint was verified and monitored. The move toward specialized managed services allowed internal IT teams to focus on core business objectives while experts handled the complex task of securing diverse, mixed-vendor fleets. By adopting these actionable steps, companies moved beyond a state of vulnerability and established a resilient foundation where every device on the network contributed to the overall security posture rather than acting as a hidden liability.
