IoT Security Software

IoT Security Software Overview

IoT security solutions (or embedded security software) secure edge devices and machines (e.g. industrial control systems, ATM machines, retail devices, etc.) through a variety of techniques including encryption or cryptographic keys, securing APIs and USB connections, and by performing scans and analytics. Comprehensive IoT security should provide multiple aspects of IoT device protection. Complete solutions should give administrators visibility into IoT networks and devices. They should also be able to secure communications to and from IoT devices, often including data encryption. They should also be able to actively monitor devices to identify and respond to attacks. Network-wide solutions should also allow for device segmentation, to mitigate the impact of an attack should it occur.


One challenge of IoT security is the sheer range of devices and use cases within the IoT ecosystem. IoT devices can range from quality of life improvements, like smart coffee-makers, to mission-critical monitoring devices embedded in energy grids. Understanding the spectrum, and severity, of the IoT environments in question is crucial to identifying which solutions are best suited to securing it. Many vendors provide IoT-specific security solutions, which are designed to cover any of the more common IoT configurations. Other vendors, particularly those in endpoint or network security, have added IoT support to existing offerings.


In addition to point solutions, IoT security can be aggregated across several different types of security tech, including:

  • Firewalls

  • Network access controllers

  • Agent-based or agentless endpoint protection

  • Network monitoring

  • IoT management systems


IoT security tools that are not part of a larger management or security suite should also be able to integrate with these systems. IoT devices are known to generate a massive amount of data. Other systems in the business should be set up to intake and process this data accordingly.

IoT Security Risks

IoT devices are still a largely emerging and evolving market. As such, there are many possibilities for the technology. There are also far fewer regulations and security standards to help protect IoT devices. Left unchecked, this can pose serious risks to businesses.


There are myriad risks for B2B and B2C businesses alike. Businesses’ consumers’ data can be highly sensitive and vulnerable in IoT devices, such as home security cameras, home mapping data, or medical tracking data from wearable devices. Failure to secure these devices can irrevocably harm consumer trust and lead to legal repercussions.


B2B organizations also face risks from insecure IoT environments. IoT vulnerabilities can jeopardize, among others:

  • Physical infrastructure monitoring systems

  • Remote firmware updates, patching, and management

  • Legal repercussions from insecure data management

In either case, IoT attacks can lead to data losses, malicious device takeovers, or devices can be used to enter other parts of the network.

IoT Security Solutions Comparison

Consider these factors when comparing IoT security solutions:

  • Solution Type: Do you need a specific point solution for specialized IoT environments? Or do you need to add IoT support to the business’s existing security stack, such as firewalls, endpoint security, etc. with support for IoT devices? Some more common IoT device configurations can be readily supported by broader security suites. For more edge-case situations, a point solution may be more effective.

  • Use Case: What IoT devices and environments are currently in use? Are there mission-critical environments that need protection, or sensitive dataflows that should be encrypted? Or are the IoT devices mostly a risk factor for intrusion elsewhere on the network? Products will come with different feature strengths. Clarity on your own use case will help guide which solution is the best fit.
