What is On-Premises IoT Security Software?
IoT (Internet of Things) security software is designed to protect connected devices and networks from cyber threats, ensuring the confidentiality, integrity, and availability of data transmitted between IoT devices. These tools monitor and secure devices, applications, and networks that are part of the IoT ecosystem, which includes sensors, actuators, smart appliances, wearables, and industrial equipment. IoT security software includes features such as threat detection, data encryption, access control, device authentication, and vulnerability management to mitigate risks from cyberattacks, unauthorized access, and data breaches. It is essential for industries like healthcare, manufacturing, transportation, and smart cities, where the IoT devices are widely used and often contain sensitive or critical data. Compare and read user reviews of the best On-Premises IoT Security software currently available using the table below. This list is updated regularly.

Airlock Digital
Airlock Digital
Airlock Digital is an application control solution that enforces a Deny by Default security posture. It enables organizations to define trusted applications, scripts, libraries, and processes at a granular level using file hash, path, publisher, or parent process. Only those explicitly defined as trusted are allowed to execute. The platform supports Windows, macOS, and Linux systems, including legacy operating systems and operational technology (OT) environments. Airlock Digital includes allowlisting and blocklisting capabilities, integrated file reputation checks via VirusTotal, and detailed logging for audit and compliance. Exception management is supported through features such as rule-based overrides and time-bound One-Time Passwords (OTPs). Centralized policy management allows consistent enforcement across large and distributed environments. The platform is available as an on-premises deployment, in the cloud, or as a managed hosted service. -

Quantum Armor
Silent Breach
Your attack surface is the sum of every attack vector that can be used to breach your perimeter defenses. In other words, it is the total quantity of information you are exposing to the outside world. Typically, the larger the attack surface, the more opportunities hackers will have to find a weak link which they can then exploit to breach your network. Professional hackers typically follow the cyber kill chain when attacking a target, and surveying the target's attack surface is normally the very first step in this process; what is known as advanced reconnaissance. Reducing the attack surface can minimize risk further down the cyber kill chain, preventing attacks before they even occur by eliminating potential attack vectors as early as possible. The cyber kill chain is a method of categorizing and tracking the various stages of a cyberattack from the early reconnaissance stages to the exfiltration of data.Starting Price: From $49/asset/month -
