Report:
The Forrester Wave™: IoT Security Solutions, Q3 2025
How does Forrester define the IoT Security Solutions market in 2025?
IoT devices are now part of every organization across all industries, locations, and sizes. These purpose-built devices (printers, sensors, smart assistants, warehouse scanners, infusion pumps, smart meters) are essential to daily operations but often lack the same local security functions as standard endpoints. Resource restrictions make IoT devices more susceptible to attack and compromise. The increasing rate of attacks and evolving complexity highlight the need for security leaders to implement proper IoT security solutions to reduce threats from these ubiquitous devices.

FAQs
Q: What does this research cover?
A: This research evaluates the nine most significant IoT security solutions providers in the market. It analyzes and scores vendors across current offering capabilities and strategy, including asset discovery, vulnerability management, risk posture management, network segmentation, threat monitoring, and device protection features. The evaluation includes customer feedback and positions vendors as Leaders, Strong Performers, or Contenders to help organizations select the right IoT security solution.
Q: Who should use this research?
A: Security leaders and IT decision-makers should use this research when evaluating and selecting IoT security solutions for their organizations. It's particularly valuable for organizations looking to: implement proper IoT security to reduce threats from connected devices; understand the differences between asset discovery, vulnerability management, and risk posture management; assess vendor capabilities across device identification, network segmentation, and threat detection; and compare vendor strengths, weaknesses, and strategic direction in the IoT security market.
Q: What are the mandatory features of vendors included in this market?
A: Vendors must natively provide core IoT security functions including: asset identification and discovery across diverse device types; threat and anomaly detection at network and device levels; asset vulnerability and risk management with prioritization capabilities. The solution must support large enterprise deployments across multiple industries (not vertical-specific), be available as a standalone purchasable product with its own SKU, and demonstrate substantial market presence with minimum $25M annual revenue.
Q: What are some reasons for not being included in this report?
A:
- Solution designed only for specific market segments or industries rather than broad enterprise use
- Product only available as bundled feature without standalone SKU and pricing
- Annual revenue from IoT security product below $25 million threshold
- Lack of demonstrated track record supporting large enterprise deployments
- Insufficient mindshare among Forrester enterprise clients
- Does not natively provide core functions (relying primarily on integrations)
- Limited recognition as competitor by other vendors in the market
Q: What should buyers consider when evaluating products in this market?
A:
- Asset discovery is crucial but not the only critical capability - stage discovery projects to uncover critical assets first before moving to communication paths and segmentation
- Vulnerability management and risk posture management are not the same - prioritize vulnerability management within IoT security solution, especially if you have enterprise risk posture management platform
- New IoT infrastructure policies must not introduce operational issues - assess impact of changes before deployment as they can have severe ramifications on business processes
- Consider operational context - inaccessible devices can delay shipping and miss customer SLAs
- Evaluate vendor's ability to review proposed policy changes to reduce operational issues
Q: How has the IoT Security Solutions market evolved in 2025?
A:
- IoT devices becoming essential to daily operations across all industries and organization sizes
- Resource restrictions in IoT devices leading to security vulnerabilities compared to standard endpoints
- Increasing rate and complexity of attacks targeting IoT devices
- Growing need to discover and classify hundreds of thousands to millions of devices across global infrastructures
- Evolution from basic asset discovery to comprehensive risk posture management
- Integration of AI/ML capabilities to improve threat detection accuracy
- Importance of network segmentation and microsegmentation for IoT security
- Need for policy impact assessment before deployment to avoid operational disruptions
Q: What differentiates Strength of Offering vs. Strength of Strategy?
A: Strength of Offering evaluates current product capabilities including device identification, vulnerability management, network segmentation, threat monitoring, and technical features. Strength of Strategy assesses the vendor's vision, innovation, roadmap, partner ecosystem, customer adoption programs, and pricing models - essentially how well-positioned they are for future market success.
