Strengthening Security from the Ground Up with Asset Visibility and Control
CIS Critical Security Controls
The CIS Critical Security Controls (CIS Controls) are among the most widely respected best-practice frameworks for cybersecurity. Designed to help organisations prioritise and implement effective defensive measures, these controls offer a clear, practical roadmap to reduce risk.
At Zerium, we help organisations align with the CIS Controls—especially those foundational to visibility, access management, and policy enforcement. As a UK-based cybersecurity consultancy and authorised seller of Sepio, we specialise in helping businesses implement the first five CIS Controls with unmatched precision at the hardware level.
Our approach focuses on a core principle:
you can’t protect what you can’t see. That starts with gaining complete visibility into all connected devices—whether IT, OT, or IoT.

What Are the CIS Critical Security Controls
The CIS Controls are a set of prioritised, measurable actions developed by the Center for Internet Security (CIS)
to help organisations defend against the most pervasive cyber threats.

Zerium’s Role in CIS Control Implementation
Zerium helps you assess, implement, and automate the first five CIS Controls—delivering both strategic oversight and technical execution.
Implement Control 1: Hardware Asset Inventory
Sepio provides real-time discovery of all physical devices connected to your network—whether they’re managed, unmanaged, authorised, or rogue. Devices are fingerprinted at the physical layer (Asset DNA), not just by IP or MAC address.
This means you gain 100% visibility, even into:
- Shadow IT or BYOD devices
- Rogue USB implants
- Spoofed peripherals
- IoT and legacy OT devices
Devices that appear compliant at the software level
Implement Control 2: Software Asset Inventory
By validating the hardware layer, Sepio supports the accuracy of your software asset inventories—ensuring only approved software runs on trusted hardware.
Support Control 3: Data Protection
Controlling endpoint access to sensitive data starts with knowing
what’s physically connected. Sepio blocks unauthorised devices from connecting, reducing risk of unauthorised data exfiltration.
Support Control 4: Secure Configuration
Ensure your security baselines extend to the hardware interface. Zerium helps design policies that prevent misconfigured or tampered devices from being used as attack vectors.
Support Control 5: Account Management
Limit account-based access to only known, trusted devices. Sepio integrates with NAC and identity tools to enforce
user + device trust as part of account control workflows.
Why Hardware Visibility is the Missing Link
Most organisations use software-based tools to track devices and access—but
these tools don’t detect what they can’t see.
Detect devices that evade traditional monitoring
Validate device authenticity using physical-layer attributes
Block or quarantine devices that fall outside approved configurations
This gives you
complete control and audit readiness for CIS compliance, starting from the physical foundation.
