Across every industry, compliance has become inseparable from cybersecurity. Governments and regulators are tightening the rules around how connected devices must be secured, authenticated, and monitored throughout their lifecycle. For enterprises with thousands—or millions—of Internet-of-Things (IoT) and Operational-Technology (OT) devices, and in some cases even millions, manual compliance is no longer sustainable. Automation is now essential.

In 2025, two frameworks stand out as the global reference points for IoT security governance: NIST 1800-32 in the United States and the EU Cyber Resilience Act (CRA). Both demand continuous visibility, verifiable identities, and lifecycle control for every connected device. To achieve compliance with these standards, organizations must implement automation and robust security practices.

Device Authority’s KeyScaler 2025 is an automated solution that provides the automation layer to enable organizations to meet compliance requirements and turn those mandates into measurable reality.

The New Compliance Landscape: Navigating Regulatory Frameworks

The rapid growth of connected ecosystems has pushed regulators to modernise their security expectations, creating a complex regulatory landscape that organizations must navigate:

• NIST 1800-32 (NIST Cybersecurity Practice Guide) establishes baseline compliance standards and requirements for IoT device identification, authentication, and authorisation.
• The Cyber Resilience Act (CRA) introduces mandatory security and update obligations, setting compliance standards for manufacturers and operators of connected products within the EU.
• EO 14028 in the US, and related initiatives worldwide, extend compliance responsibilities and standards across the entire supply chain.

For Chief Information Security Officers (CISOs) and compliance leaders, these frameworks share one principle: security must be continuous, measurable, and provable. That is impossible without automating identity and policy management.

Why Manual Compliance Fails at Scale

Traditional compliance models rely on periodic audits, spreadsheets, and human oversight. In an environment where device counts double every 12–18 months, such methods collapse under their own weight.

Manual processes fail because:

1. Devices multiply faster than teams can document them.
2. Certificate renewals lapse, creating hidden vulnerabilities.
3. Regulatory mappings face frequent changes in requirements, requiring constant policy updates.
4. Evidence collection is fragmented, making audits slow and costly.

Managing compliance efforts at scale becomes increasingly complex without automation.

Without automation, compliance becomes a perpetual backlog — reactive rather than proactive.

Automated Machine Identity Management: The Compliance Catalyst

Machine identities are to devices what user credentials are to people. They confirm authenticity, enable encryption, and define trust boundaries. Yet most organisations still issue, track, and revoke certificates manually.

KeyScaler 2025 automates the entire lifecycle:

• Provisioning: Securely issues unique cryptographic identities to every device.
• Rotation: Renews certificates automatically before expiry, maintaining compliance continuity.
• Revocation: Instantly invalidates compromised identities.
• Auditability: Records every transaction in tamper-proof logs for regulators.

This automation aligns directly with both NIST and CRA requirements, providing demonstrable proof of continuous governance.

Automation enables organizations to meet evolving cybersecurity standards, such as those set by NIST and the Cyber Resilience Act (CRA), by translating complex requirements into actionable, machine-enforced policies.

Internet of Things (IoT) Overview

The Internet of Things (IoT) is transforming industries by connecting billions of physical devices—from industrial sensors and medical equipment to smart vehicles and home appliances—into vast, data-driven networks. These IoT devices collect, transmit, and analyze data to drive efficiency, innovation, and smarter decision-making across sectors such as healthcare, transportation, energy, and manufacturing.

However, the rapid expansion of IoT devices has introduced a significant challenge: ensuring robust IoT security compliance. As the number of connected devices grows exponentially, so does the complexity of securing these networks and maintaining the integrity of the data they generate. Regulatory frameworks like the EU Cyber Resilience Act are being implemented to address these concerns, setting new standards for IoT security and mandating that organizations protect their IoT systems against evolving threats. In this evolving landscape, achieving and maintaining security compliance is essential for safeguarding data, building customer trust, and ensuring the long-term success of IoT deployments.

Device Management

Effective device management is at the core of securing IoT devices and ensuring ongoing compliance. With the proliferation of connected devices, organizations must implement comprehensive security measures—including encryption, secure authentication, and authorization—to protect sensitive data from unauthorized access and cyber security threats.

Continuous monitoring of IoT devices is essential for detecting unusual patterns or vulnerabilities in real time, enabling organizations to respond to security threats in a timely manner. Automated tools streamline critical device management processes such as vulnerability scanning, patch management, and firmware updates, ensuring that devices remain compliant with relevant regulations and security policies. By adopting a proactive stance and leveraging automation, organizations can reduce the risk of breaches, maintain the integrity of their IoT systems, and ensure compliance with evolving regulatory requirements.

Compliance Challenges in IoT

Navigating the compliance landscape in the IoT industry presents a significant challenge for organizations and manufacturers alike. The sheer number of IoT devices deployed across various locations, combined with the complexity of interconnected IoT systems, makes it difficult to achieve and maintain continuous compliance. Regulatory frameworks such as the EU Cyber Resilience Act require organizations to implement stringent security measures, protect sensitive data, and ensure data integrity across all devices.

IoT manufacturers must keep pace with evolving security standards and regulatory requirements, all while managing the risks posed by cyber security threats. Ensuring compliance involves not only meeting technical security standards but also implementing robust processes for compliance verification and risk management. Automated solutions are essential for continuously monitoring compliance status, identifying vulnerabilities, and ensuring that every device meets relevant regulations. By embracing automation, organizations can overcome the challenges of scale and complexity, reduce the risk of non-compliance, and protect both their data and reputation.

The Business Impact of Automated Compliance

Beyond meeting regulations, automation delivers tangible business value:

• Reduced Operational Costs and Cost Savings: Automation leads to significant cost savings by reducing manual certificate management hours, minimizing expenses related to audits, and lowering the risk and costs associated with security breaches.

Integrating NIST and CRA into Zero Trust Architectures

Both frameworks explicitly reference the Zero Trust principle: every device must authenticate before access is granted, and that trust must be continuously verified to protect critical systems within IoT environments.

KeyScaler 2025 operationalises this by:

1. Assigning every device a verifiable identity.
2. Enforcing context-aware policies based on location, firmware state, and risk score.
3. Continuously evaluating behaviour through AI-driven analytics.

Zero Trust security measures are essential for securing IoT networks, ensuring that only authorized devices and users can access sensitive resources and reducing vulnerabilities across distributed infrastructures.

This creates a closed-loop compliance ecosystem where each device proves its integrity in real time — a requirement reflected in both NIST and CRA guidance.
