Almost any physical device can become IoT-enabled by integrating cellular connectivity, and as the number of connected devices grows, so does the attack surface that enterprises need to secure. IoT devices are frequently deployed in the field, transmit sensitive data, and may have limited security capabilities compared with traditional computers, making secure connectivity and data routing a critical part of IoT deployments.
A Virtual Private Network (VPN) can help enterprises protect data in transit, control how IoT devices communicate with their networks, and reduce direct exposure to the public internet.
What Is a VPN for IoT?
A VPN for IoT is a Virtual Private Network that creates a secure connection between IoT devices and an enterprise network, helping protect data in transit and reduce direct exposure to the public internet. Instead of relying on an open connection, an IoT VPN can route device traffic through a secure, encrypted tunnel while giving enterprises greater control and visibility over how connected devices communicate with applications and networks.
For businesses managing large numbers of connected devices, an IoT VPN can provide a consistent approach to securing communications across distributed IoT deployments.
How It Works
A VPN secures IoT connections by extending a company’s private network out to cellular connected devices. This allows the company’s application servers to communicate directly to cellular connected devices without requiring the devices to be directly connected to the Internet with public IP addresses.
VPNs essentially route Internet traffic through a server which may be located anywhere, and the connections appear as originating from the location of the server. A number of VPN IoT security solutions are available, including VPN software clients, pre-configured routers, customer-provided routers, cloud-based routers, and custom solutions.
In an IoT deployment, this allows enterprise applications and servers to communicate securely with cellular connected devices across distributed environments. Depending on the architecture, an IoT VPN can help limit direct exposure to the public internet while protecting data as it moves between devices, networks, and applications.
IoT VPN solutions can be deployed in different ways depending on the device, network, and business requirements. Options may include VPN software clients, pre-configured routers, customer-provided routers, cloud-based routers, or custom solutions. This flexibility allows enterprises to apply secure connectivity across different device types and deployment environments.
Benefits of VPN for IoT Security
Because most IoT devices don’t have the built-in firewalls and antivirus software found in PCs and smartphones, and the ones that do tend to be insufficient at best, a VPN can prevent outsiders from intercepting traffic. This provides companies with peace of mind knowing they have reliable encryption, authentication, privacy, and security of network traffic and data.
VPN solutions can be rapidly deployed and are designed to secure IoT networks by extending connections to mobile devices without using public IP addresses. KORE VPN solutions come with high-reliability, multi-path protection that offloads end-to-end encryption to the network, maximizing IoT device computer power.
Is a VPN Secure Enough for IoT?
For many IoT deployments, a properly configured VPN can provide strong security by encrypting data in transit and reducing direct exposure to the public internet. Because IoT devices may have limited security capabilities compared with traditional computers, securing communications at the network level can provide an additional layer of protection.
For enterprises managing IoT VPNs at scale, a managed approach can also simplify security by handling encryption and authentication at the network level while providing greater visibility and control over connected devices and their communications. The right approach depends on the organization’s security requirements, device architecture, network environment, and deployment scale.
