South America Internet Of Things (IoT) Security Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

South America Internet Of Things (IoT) Security Market Trends and Insights

Expansion of Connected Industrial and Critical-Infrastructure Assets

Industrial digitalization is increasing the number of connected assets across oil and gas, mining, hydropower, and manufacturing sites. These assets require security coverage throughout their operating life, not only at the time of installation. A refinery or hydropower facility can operate equipment from 5 or more vendors, with different firmware practices and authentication methods. That mix makes a standardized perimeter defense insufficient for many operating environments. Security providers, therefore, need to combine asset visibility, integration work, and ongoing monitoring for each site. The South America Internet of Things (IoT) security market is benefiting as security engagements extend from one-time deployments into longer service relationships.

Rising IoT-Targeted Cyberattacks and Operational Disruption Risks

Cyberattacks on industrial environments are increasing the need for continuous monitoring among operators in South America. Manufacturing and energy utilities remain exposed because connected devices can provide entry points to broader operational systems. The fastest incidents in 2025 reached full data exfiltration in 1.2 hours, compared with 4.8 hours in 2024, reducing the time available for reactive response measures. Firmware in industrial devices may not be patched immediately because maintenance activity can interrupt production. Cloud-delivered managed security and SECaaS offerings address this issue through continuous detection and response coverage. This operating need supports demand for the South America Internet of Things (IoT) security market beyond traditional perimeter security tools.

Brazil PAC 4.0 and Smart-City Security Procurement

Brazilian smart-city programs are raising the security requirements for video sensors, data platforms, and connected urban infrastructure. Procurement requirements involving encryption, micro-segmentation, anomaly detection, and ISO/IEC 27001 can shift security spending toward recurring audits and monitoring. The resulting contracts favor service models that provide regular compliance support instead of a single capital purchase. ABNT and ABINC approved ABNT NBR ISO/IEC 20924:2025 and ABNT NBR ISO/IEC 30173:2025 during 2025.^{[1]Associação Brasileira de Internet das Coisas, “ABNT and ABINC Create Technical Standards for IoT,” ABINC, abinc.org.br} A dedicated IoT device cybersecurity standard was planned for 2026, indicating a broader focus on device security requirements. These developments make Brazil an important source of regulatory-led opportunity for the market.

5G, NB-IoT, and Open Gateway Security Upselling

The rollout of 5G and NB-IoT networks is adding new device types to telecom and enterprise security environments. ANATEL Act No. 2105/2025 introduced certification requirements for devices that use 5G NB-NTN, 5G RedCap, and 4G LTE Cat 1bis technologies, effective from August 2025. The requirements link device deployment to current 3GPP standards and security assessment practices. STMicroelectronics obtained ANATEL certification for its ST87M01 NB-IoT module in Brazil during June 2026, supporting smart metering, street lighting, and agricultural deployments. Each new device population increases the number of endpoints requiring identity, access, network, and lifecycle security management. The South America IoT security market can benefit as telecom providers and managed service firms add security alongside connectivity services.

High Implementation and Integration Costs

IoT security deployments can require hardware, specialized labor, and continuing integration support. This cost structure is difficult for many small and mid-size industrial enterprises to sustain outside São Paulo, Buenos Aires, and Santiago. Operators frequently manage devices from several vendors with incompatible application programming interfaces, authentication approaches, and data formats. Custom work is often required before a central platform can collect and interpret device telemetry. The South America Internet of Things (IoT) security market, therefore, faces slower adoption where an operator cannot justify an extensive on-premise security stack. Cloud-based models can reduce some initial infrastructure needs, but they do not remove the cost of assessing and integrating legacy operational technology.

Fragmented IoT Standards and Interoperability Requirements

South American suppliers must often work across country-specific requirements and international security frameworks. Brazil uses ANATEL requirements, while companies may also need to consider ISO/IEC 27001 and IEC 62443 during product selection and audits. This multi-standard environment increases the time needed to localize products and assess vendor compliance. Integration is also difficult because many industrial control systems and SCADA platforms were not designed with open security application programming interfaces. Energy, water, and manufacturing operators can encounter gaps when linking legacy operational technology with modern IoT security platforms. These requirements can delay deployments in the South America Internet of Things (IoT) security market, particularly when a customer has a varied installed base.

Segment Analysis

By Security Type: Network Security Leads While Cloud Security Accelerates

Network Security accounted for 41.32% of the South America IoT security market in 2025, making it the largest security category. Industrial operators continue to prioritize the network layer because connected endpoints communicate through enterprise and operational networks. Phishing activity, malicious scripts, and web-based threats remain relevant risks for industrial control system users in the region. Kaspersky reported that ICS computers in South America faced email-client threats at 1.9 times the global average during the fourth quarter of 2025. The same report showed exposure to malicious phishing pages at 1.5 times the global rate during that quarter. These conditions support continuing demand for network visibility, segmentation, intrusion prevention, and threat monitoring.

Cloud/Virtual Security is projected to expand at a 35.76% CAGR from 2026 to 2031, the fastest rate among security types. It enables centralized monitoring of distributed device fleets without requiring a full security operation at each site. This model is useful for industrial facilities located far from major cybersecurity talent pools. Endpoint/Device Security is becoming increasingly relevant as device certification requirements draw greater attention to security controls at the hardware and firmware levels. Application Security also addresses risks created by connected dashboards, cloud-native industrial applications, and digital control interfaces. The market is likely to use network controls as its foundation while placing more monitoring and management functions in cloud environments.

By Component: Solutions Lead While Services Gain Ground

Solutions accounted for 57.74% of the South America Internet of Things (IoT) security market size in 2025. The category includes Identity and Access Management, Public Key Infrastructure, DDoS protection, IDS/IPS, encryption, and tokenization. These capabilities help organizations establish device identity and protect communications across manufacturing and energy environments. Machine-to-machine authentication is particularly important when large device fleets operate with limited direct human intervention. SABESP, Vivo, and IDEMIA Secure Transactions announced a 14-year partnership in August 2026 to connect 4.4 million eSIM-secured smart water meters in São Paulo City and São José dos Campos.^{[2]SABESP, Vivo, and IDEMIA Secure Transactions, “SABESP Partners with Vivo and IDEMIA Secure Transactions to Power the World's Largest IoT Initiative for a Secure and More Sustainable Water Management in Brazil,” IDEMIA, idemia.com.} Such deployments demonstrate the operational scale at which security, identity, and connectivity controls need to work together.

Services are projected to expand at a 35.37% CAGR from 2026 to 2031. Managed Security Services and Professional Services can support companies that lack dedicated staff for ongoing detection, response, tuning, and incident handling. Implementation services also remain important where older devices need to connect with modern monitoring tools. Vendors can use service relationships to address the operational gap that follows an initial technology purchase. The South America IoT security industry is consequently supported by demand for both tools and the skilled personnel needed to operate them. Service delivery becomes more important when customers need continuous protection rather than periodic product upgrades.

By End-User Industry: Smart Manufacturing Leads and Energy Utilities Accelerate

Smart Manufacturing held 27.63% in 2025, the highest share among end-user industries. Automotive and agri-food facilities are deploying connected sensors and robotics that require network segmentation and firmware integrity monitoring. These measures support production continuity when connected systems are exposed to malicious activity or configuration failures. Manufacturing sites frequently combine older industrial control equipment with newer IoT hardware. This combination can create a need for security controls that work across varied protocols and device generations. The South America IoT security market is therefore supported by manufacturers that need to protect expanding industrial data flows without interrupting plant operations.

Energy and Utilities is projected to expand at a 36.36% CAGR from 2026 to 2031, the fastest rate among end-user industries. Energy systems face operational consequences when security incidents affect control, monitoring, or communications equipment.

Government and Smart Cities are also becoming significant buyers of network security and identity management tools for urban IoT infrastructure. Retail and Logistics are building demand through connected supply chains and cold-chain monitoring systems in Brazil and Argentina. These end-user groups broaden the customer base for the South America Internet of Things (IoT) security market, even as manufacturing and utilities remain the central sources of demand.

By Deployment Mode: Cloud/SECaaS Leads and Hybrid Edge Gains Relevance

Cloud/SECaaS held 46.91% in 2025, making it the largest deployment mode. Many operators outside major metropolitan areas cannot maintain a full on-site security operations team. Cloud-delivered monitoring and response provide an accessible starting point for those customers. The approach also allows providers to support clients across multiple countries through centralized service capacity. It is especially relevant where industrial facilities have limited local access to certified IoT security engineers. The South America Internet of Things (IoT) security market is using Cloud/SECaaS to align security coverage with the region's uneven distribution of technical talent.

Hybrid Edge is projected to expand at a 35.54% CAGR from 2026 to 2031. Oil fields, remote mining sites, hydropower stations, and rural agricultural facilities often require local processing due to latency and connectivity constraints. These sites can still benefit from centralized threat intelligence and remote management. Neoenergia deployed a multi-access IoT connectivity ecosystem in Brazil in early 2026, combining private LTE, public LTE, and satellite connectivity via a single modem platform. On-premise deployments retain a role in high-security government and defense-related settings where data sovereignty requirements limit cloud connectivity. Hybrid architectures address the practical need to combine local operations with broader security oversight across the market.
