In today’s cybersecurity landscape, layer one visibility is essential for safeguarding your organization’s network. Layer One, referring to the physical layer of the OSI model, involves the transmission of data over physical connections like cables and wireless signals. Ensuring visibility at this level is crucial for protecting hardware assets and preventing breaches. This is an integral aspect of Cyber-Physical Security, which combines both physical and cybersecurity strategies.
With layer one visibility as part of your Cyber-Physical Security strategy, you can monitor and manage all hardware assets—whether managed, unmanaged, or hidden. This visibility allows you to detect security threats at the physical layer that may not be visible to traditional network monitoring tools. By ensuring that every device on your network is accounted for and secured, you can prevent vulnerabilities that could jeopardize your organization’s security.
Sepio’s Asset Risk Management (ARM) solution provides unmatched layer one hardware visibility, utilizing advanced data fingerprinting technology to uncover all devices on your network. Even devices that are often invisible to other security tools can be detected, ensuring that every device is continuously monitored and protected.
Why is Layer One Visibility Essential for Cyber-Physical Security?
Traditional cybersecurity solutions often fail to detect unmanaged and rogue devices, leaving your network exposed to hidden risks. Sepio’s Asset Risk Management (ARM) addresses this gap by providing Layer One Visibility, utilizing data from the physical layer of your network. This approach ensures that all devices—whether managed, unmanaged, or hidden—are detected, even those that conventional security tools may overlook.
Why is Layer One Visibility essential for Cyber-Physical Security? Unauthorized devices and malicious hardware can bypass traditional defenses, leading to serious vulnerabilities. By focusing on the physical layer, Sepio ensures no device goes undetected, enabling early identification and mitigation of threats before they escalate into significant risks.

With Sepio’s ARM, you can gain insights into:
- Managed Devices: Ensure all devices authorized for use within your network are properly tracked and secure.
- Unmanaged Devices: Identify and mitigate risks from devices that may not be directly controlled by your organization’s IT infrastructure.
- Hidden Devices: Detect devices that are not immediately visible to conventional security measures, allowing you to uncover potential threats that could compromise your network.
Key Features of Sepio ARM
Sepio’s platform offers unparalleled layer one visibility into the physical layer of your network, safeguarding against network implants, rogue devices, and other layer one threats.
What sets Sepio apart is its non-intrusive approach. During deployment, Sepio avoids probing network traffic or using discovery protocols, ensuring that no proprietary data is monitored. This allows for smooth, efficient integration into your network without disruption. Additionally, Sepio significantly reduces the risk of employee negligence, strengthening your cybersecurity posture.
- Hardware Fingerprinting Technology: By using advanced hardware fingerprinting technology, Sepio ARM uniquely identifies each device based on its physical characteristics. This ensures that no devices, even those operating outside traditional network controls, are left unchecked.
- Layer 1 Visibility: Unlike other solutions, Sepio ARM operates at Layer 1 to detect all devices, even those that are invisible to conventional network monitoring methods.
- No Traffic Monitoring Needed: A key advantage of Sepio, is that it doesn’t require continuous traffic monitoring. Instead, it passively collects device-related data, providing a seamless and non-intrusive way to manage your hardware assets without impacting network performance.
- Real-Time Alerts and Risk Mitigation: Sepio continuously scans your environment for rogue or unknown devices and sends real-time alerts to your security team. This proactive approach helps mitigate risks quickly, ensuring that any threats posed by unauthorized hardware are neutralized before they can exploit your network.
- Comprehensive Asset Inventory: With Sepio ARM, you can maintain a comprehensive and up-to-date inventory of all devices in your network. This makes managing compliance, auditing, and risk assessments easier and more efficient.
