CDTV Sepio HotSeat – Yossi Appleboum

In this exclusive Cyber Defense TV (CDTV) HotSeat interview, Sepio CEO Yossi Appleboum shares insights into one of the most critical challenges in modern cyber defense: Asset Risk Management (ARM) in an era of increasingly sophisticated hardware-based attacks.

As organizations accelerate digital transformation, the number of connected devices continues to grow, expanding the attack surface and increasing exposure to risk. While many security strategies focus on software-based threats, modern cyber defense must also address a less-protected attack vector: the hardware layer.

In this conversation, Yossi explains how Sepio’s approach to hardware cybersecurity strengthens cyber defense capabilities by delivering deep visibility, accurate risk scoring, and policy enforcement. This enables organizations to better secure critical infrastructure and reduce exposure to emerging threats.

Key Insights from the Interview

The Hidden Risks of Unmanaged Assets
Modern IT and OT environments are filled with unknown or unauthorized devices, from shadow IT to rogue hardware implants. Yossi emphasizes a fundamental principle of effective cyber defense: you cannot protect what you cannot see. Without full visibility, organizations remain exposed to hidden risks.

Rogue Devices & Layer 1 Visibility
Traditional security tools such as NAC, EDR, SIEM, and IDS operate above the physical layer, leaving a critical blind spot. Sepio’s research highlights how rogue devices, whether maliciously introduced or unintentionally connected, can evade detection and undermine cyber defense strategies by providing stealthy access to attackers.

Why Zero Trust Hardware Access
Zero Trust is built on the principle of “never trust, always verify,” yet most implementations stop at the software or network layer. Yossi explains how Sepio extends Zero Trust principles to the hardware layer, strengthening cyber defense by ensuring every connected asset is verified before being trusted.

Real-World Use Cases
Drawing on real-world scenarios, Yossi highlights how organizations have been compromised through hardware-based attacks, including supply chain infiltration and insider threats. He also explains how Sepio enables enterprises and government bodies to improve cyber defense by detecting, assessing, and mitigating these risks before they escalate.

Strengthening Cyber Defense with Hardware Visibility

Sepio is a pioneer in Asset Risk Management, delivering a platform designed to eliminate hardware-level blind spots and enhance cyber defense strategies through:

  • Complete Asset Visibility: Identify and classify all connected IT, OT, and IoT devices in real time
  • Risk-Based Policy Enforcement: Automate security decisions based on accurate device risk profiles
  • Zero Trust Hardware Access: Ensure only trusted and verified devices are allowed to connect
  • Protection Against Supply Chain Threats: Detect and stop hidden hardware risks before they impact operations

By eliminating blind spots and enabling proactive risk management, Sepio empowers security teams to stay ahead of hardware-based threats. before they become incidents.
