IoT security and compliance services
SumatoSoft audits existing IoT networks for security and compliance, provides consulting services to businesses concerned with the security of their IoT systems, and designs IoT systems from scratch that meet regulatory requirements. We provide IoT security at the device, network, cloud, and application levels.
Key areas where we strengthen your IoT system
Our IoT security and compliance services
Below are the main areas in which SumatoSoft works with IoT security. We flexibly assemble the proper service set for your product and industry.
Risk assessment and threat modeling
- We start by understanding exactly what needs to be protected. To do that, we conduct an IoT risk assessment and compile an asset map.
- Next, we perform IoT threat modeling for key scenarios, drawing on best practices and real-world attack cases.
- As a result, you receive a prioritized list of risks with a change plan for devices, networks, the cloud, and processes.
Secure architecture and development
- We design IoT architecture with IoT cybersecurity and compliance in mind. We define network zones, encryption methods, and authentication points.
- The team implements these solutions into the code and infrastructure, laying the foundation for secure IoT solutions.
- We use a secure development, testing, and release cycle, and security doesn’t slow down feature delivery; it’s built into the proce
Compliance and regulatory requirements
- We cover regulatory compliance for IoT tailored to your market.
- We work with IEC 62443 compliance for IoT in industrial environments.
- We develop solutions that pass inspections more easily in factories and on the shop floor.
- For IoT in the EU, we build GDPR compliance for IoT devices.
- We configure consent collection, storage, anonymization, and data deletion rights.
- We rely on the NIST IoT cybersecurity framework guidelines where relevant.
- We document policies and artifacts that auditors and security teams expect.
Firmware and secure OTA updates
- Firmware is a common entry point for attacks.
- We strengthen IoT firmware security and build processes for secure OTA updates.
- We add signatures, integrity checks, and secure rollback capabilities, while accounting for device memory, network, and power limitations.
- The result is a managed update process critical to IoT vulnerability management and the closure of discovered vulnerabilities.
Device identity and authentication
- We configure IoT device identity management (IoT) so each device has a stable digital identity.
- We implement IoT device identity management solutions and use certificates, secure key storage, and rotation.
- We build IoT device authentication and identity management, so only trusted devices can connect to your network and services.
- This reduces the risk of device spoofing and man-in-the-middle attacks.
Data protection and encryption
- We take responsibility for IoT data encryption throughout the operational lifecycle: data is encrypted on the device, in transit, and in storage.
- We restrict data access by role and scenario and log access, changes, exports, and attempts to bypass rules.
- This is important for personal data, trade secrets, and telemetry, and builds trust in the platform and ensures compliance.
Security testing and vulnerability management
- We conduct IoT penetration testing across device, application, and cloud layers. This includes IoT penetration testing services according to the agreed-upon scope.
- We use IoT vulnerability assessment tools and services to identify weaknesses before attackers find them.
- We then integrate IoT vulnerability management as a process by recording vulnerabilities, setting deadlines, and repeating checks.
Industry service packages
- For healthcare, we consider HIPAA, GDPR, medical device requirements, and patient risks.
- For manufacturing and OT, we focus on network segmentation, IEC 62443, and line and equipment access.
- For industrial IoT platforms, we connect standard requirements with controls in your stack.
- This way, you receive an IoT security action plan tailored to your business, industry, and regulators.

IoT security regulations readiness
IoT security regulations evolve worldwide, and at SumatoSoft, we stay on top of these changes to ensure our Clients’ businesses remain compliant and secure. These are not all, but the most requested regulations we follow:
EU Cyber Resilience Act (CRA)
Expected to be enforced by 2027, this act introduces mandatory security-by-design principles and lifecycle support for products with digital elements.
UK Product Security & Telecommunications Infrastructure (PSTI) Act
A UK law that bans default passwords in consumer IoT devices and requires transparency about security update support and vulnerability disclosure policies.
EU NIS2 Directive
An expanded EU cybersecurity directive that extends requirements to more sectors (including critical infrastructure using IoT) and imposes stricter risk management, incident reporting, and supply chain security obligations.
NIST IoT Cybersecurity Framework
A U.S. framework from NIST that outlines best practices for secure IoT development and risk management.
FDA Medical Device Cybersecurity Requirements
U.S. FDA guidance has ramped up cybersecurity expectations for IoT medical devices, requiring manufacturers to address security in pre-market submissions and to maintain post-market monitoring and updates.
6 principles of IoT security
Our mandatory six principles help build IoT security at the device, network, cloud, and application levels and simplify subsequent compliance.

IoT technologies we work with
Our IoT security and compliance process
We begin by examining your current IoT system. Unlike developing from scratch, security requires analyzing the existing architecture, data, firmware, and operations. The goal is to understand the risks, mitigate vulnerabilities, and ensure the solution complies with the required standards.
We conduct an audit of the existing IoT platform: examine devices, the network, the cloud, APIs, and support processes. Then, we analyze threats, identify technical gaps, and regulatory incompatibilities. This helps us understand what needs to be changed and in what order.
We analyze your architecture and data landscape: how devices operate, how messages flow, and how keys are stored. We then compare the approaches against IEC 62443, GDPR, HIPAA, and other applicable regulations. The result is our proposal of changes that strengthen the system without complex redesigns. For clarity, we create a document with checkpoints and recommendations.
We help address identified risks. This could include cloud setup, network segmentation, API protection, or OTA redesign. During hardening, we work on firmware security (IoT) and devices, configure IoT device identity management, document new rules, and update processes.
To verify that your system has become more secure, we conduct technical tests, including IoT penetration testing. We also analyze logs, channels, and device behavior. To ensure compliance alignment and help you meet required standards without unnecessary bureaucracy, we prepare audit materials.
Security is a process: we update firmware, patch vulnerabilities, and validate configurations. We provide IoT vulnerability management, monitor regulatory changes, and help organizations adapt to new standards. This way, we ensure your business remains resilient and ready for audits.
Benefits of making your IoT network secure and compliant

Frequently asked questions
What does an IoT risk assessment include?
We assess devices, networks, clouds, and APIs, then evaluate risks, create a threat map, and identify critical points. This helps us understand what needs to be addressed first. An audit is the first step to truly securing the IoT.
How does IoT threat modeling work?
We describe attack scenarios on devices, gateways, communication channels, and services. Then, we examine what could go wrong and how to stop it. The threat model helps prioritize and mitigate incident risk.
How do you ensure IoT firmware security and best practices for its updates?
We include signature verification, bootloader protection, and integrity control. The OTA process is encrypted, rollback-enabled, and keys are securely stored. This ensures that firmware cannot be tampered with, even with physical access.
How do you manage the identity of IoT devices?
Each device receives its own key or certificate. We configure registration, rotation, and revocation. Only trusted devices can connect to the network and services.
How do you ensure your Clients comply with industry regulations?
We analyze the system and compare it against the applicable regulations, including IEC 62443, GDPR, HIPAA, NIST, FDA, and others. Then, we prepare a changelog and artifacts for audit.
