Securing IoT Devices: Why a Hybrid Approach is Needed
Picture a prison yard. All the inmates are together, guarded by someone in a tall tower scanning for trouble. That’s?one?way to monitor threats—but if something slips by the guard’s line of sight, everyone is at risk.
Now picture each inmate in their?own?cell, with guards inspecting every entrance and exit. Every piece of mail, every visitor—all carefully reviewed. That level of isolation and oversight significantly reduces the chance of any inmate posing a risk to others.
?How does this relate to IoT security? Most solutions, like Nessus from Tenable, rely largely on active scanning (think: the guard in the tower). They do a solid job at spotting open ports and vulnerabilities, but sophisticated IoT devices—often having no or very few open ports—may stay hidden. Additionally, active scanning of resource-constrained IoT devices commonly results in device disruptions leaving untested and potentially vulnerable devices on the network. ?
?Passive monitoring solutions rely on logs or packets potentially leaving them blind to devices that encrypt traffic & to vulnerabilities that require active inspection. They typically also require complex deployments, private packet collection, solution tuning and expensive licensing.
?And once on your network, if one device is compromised, the entire “yard” can be at risk.
Enter IoTSecure.
IoTSecure combines?both active?scanning?and?passive?monitoring to discover every IoT device—even the ones with few or no open ports. More importantly, our?Dynamic Micro-Segmentation (DMS)?automatically isolates each device in its own secure “cell,” keeping threats contained and preventing lateral movement.
?Key Highlights:
·??????? Hybrid Discovery:?We?actively?scan like a guard +?passively?monitor outbound traffic to catch stealthy devices others miss, safely, with any device or network interference.
·??????? Dynamic Micro-Segmentation (DMS):?Automatic isolation of each device, so a single compromised device can’t take down your entire network.
·??????? Real-Time Threat Detection:?We constantly watch for anomalies, ensuring suspicious behavior is quickly flagged and contained.
·??????? Affordability combined with Lightning Fast Deployment: Be up and running is as little as 5 minutes with no agents, no network TAP/SPAN ports or sensitive data collection.
?Stop relying on guard-tower-only security. Keep your IoT devices safe by putting them in individualized, well-monitored “cells.”
