Introduction: The Business Case for IoT Security

IoT security has traditionally been viewed as a cost centre, a necessary but expensive line item on the IT budget. But this perspective is outdated. As enterprises deploy billions of connected devices across healthcare, automotive, energy, and manufacturing, all connected via the internet as the backbone of IoT deployments, the financial impact of failing to secure them has skyrocketed.

The importance of measuring and understanding the value of IoT investments is now crucial for organizations seeking to justify and assess the success of their IoT solutions. Data breaches, regulatory fines, downtime, and reputational damage are now so severe that IoT security must be seen as a business enabler rather than a sunk cost. The process of IoT adoption is central to driving business transformation and ROI, as organizations leverage new technologies to realize operational and strategic benefits.

The question for CISOs, CFOs, and business leaders is no longer “Do we need IoT security?” but rather “What return on investment (ROI) can IoT security deliver?” By embracing automation and identity management, organisations can quantify the benefit of IoT security investments through measurable financial gains while strengthening resilience and compliance.

This article explores how to calculate the ROI of IoT security, why automation is the key to realising savings, and how Device Authority’s KeyScaler 2025 and IoT Security ROI Calculator can help enterprises make data-driven investment decisions.

The True Cost of IoT Breaches

Understanding ROI begins with understanding the financial impact of IoT breaches. Studies show that breaches involving IoT devices are among the most costly due to their impact on operations and supply chains. As IoT deployments scale from pilot projects to large-scale implementations, there is more risk related to security, compliance, and operational challenges. Organizations must address various risks, including data breaches, operational disruptions, and regulatory issues, when managing large-scale IoT environments.

Key cost drivers include:

• Data breaches: Sensitive information exfiltrated from unmanaged devices can lead to fines, lawsuits, and lost trust.
• Operational downtime: In industries like manufacturing or healthcare, downtime caused by compromised devices can cost millions per hour.
• Remediation expenses: Forensics, patching, and recovery are more complex with IoT due to diverse device types and lifecycles.
• Reputational damage: Customers and partners may hesitate to engage with organisations that fail to secure their connected ecosystem.
• Regulatory penalties: Non-compliance with frameworks such as NIST, CRA, or WP.29 carries financial and legal consequences.

IBM’s Cost of a Data Breach Report highlights that average breach costs continue to rise year-on-year, and IoT-related incidents often exceed these averages due to scale and complexity.

Why Traditional Security Approaches Are Inefficient

Traditional security tools and manual processes struggle to deliver ROI. They are resource-intensive, slow to scale, and leave gaps in coverage. For example:

• Manual certificate management: Rotating and revoking device certificates manually is error-prone and labour-intensive.
• Fragmented tools: Using multiple siloed platforms for IoT security increases licensing costs and creates inefficiencies.
• Inability to scale: Legacy systems cannot keep pace with millions of connected endpoints.

These inefficiencies not only increase costs but also reduce the likelihood of achieving compliance, which further exposes organisations to fines.

Challenges in IoT Deployments

Deploying IoT solutions presents a unique set of challenges for businesses operating in an increasingly connected world. One of the foremost concerns is implementing robust security measures to safeguard IoT devices and network infrastructure against evolving threats. As organizations expand their IoT projects, they must also manage ongoing costs related to continuous monitoring, device maintenance, and system updates. Integrating new IoT systems with existing infrastructure can be complex, often requiring significant initial investment and careful planning to ensure seamless operation and regulatory compliance.

Business leaders must also anticipate future technological advancements and adapt their strategies accordingly to maintain a competitive edge. The dynamic nature of the IoT ecosystem means that what works today may need to be re-evaluated tomorrow. Strategic planning, deep knowledge of IoT applications, and a clear understanding of business needs are essential for maximizing the tangible value and revenue growth that IoT investments can deliver. By proactively addressing these challenges, businesses can unlock the full potential of their IoT solutions and achieve sustainable ROI.

How Automation Unlocks IoT Security ROI

Automation is the foundation of achieving ROI in IoT security. Platforms like KeyScaler 2025 remove manual overhead, reduce risk, and deliver financial savings through:

• Automated device discovery: Identifies and secures every device instantly, preventing breaches from shadow IoT.
• Credential provisioning and management: Issues, rotates, and revokes certificates without human intervention.
• Policy enforcement: Applies Zero Trust policies uniformly across devices, reducing compliance failures.
• Continuous monitoring: Detects anomalies and reduces downtime through real-time insights.
• Compliance reporting: Generates auditable logs automatically, cutting the costs of regulatory audits.

These capabilities eliminate the need for resource-heavy manual tasks and reduce the likelihood of high-cost incidents.

Calculating the ROI of IoT Security

ROI is typically calculated using the formula:

ROI = (Total Benefits – Total Costs) ÷ Total Costs x 100%

For IoT security, benefits include:

• Reduced breach remediation costs
• Lower compliance overheads
• Minimized downtime and operational losses
• Extended device lifecycles through proactive monitoring
• Improved customer trust and retention

Costs include:

• Platform subscription or licensing
• Initial deployment and integration
• Training and change management

By quantifying these variables, organisations can calculate both direct and indirect returns on their IoT security investments.

Understanding Ongoing Costs in IoT Security

For many organizations, the true cost of IoT security extends far beyond the initial deployment. Ongoing costs—such as continuous monitoring, predictive maintenance, and data management—are critical factors that can impact the long-term success of IoT deployments. As IoT ecosystems grow, so does the complexity of managing devices and network infrastructure, increasing the risk of operational disruptions and potential vulnerabilities.

Businesses must also account for the expenses associated with remote monitoring, maintenance agreements, and ensuring compliance with evolving regulations. These ongoing investments are essential to secure IoT environments, protect customer trust, and maintain a competitive edge in the connected world.
