FOR CISOs, NETWORK ARCHITECTS & IT SECURITY MANAGERS
Cyber & IT Infrastructure Security
Your network security stops at the cable. We secure the physical layer your firewalls cannot see: the ports, the peripherals, the devices plugged into your edge.
THE BLIND SPOT
The Attacks Your SOC Cannot See
Your endpoint detection, your firewall rules, your SIEM correlation logic: none of it covers what happens at the physical port. These three attack categories bypass your entire security stack because they operate below the software layer.
Rubber Ducky USB Exploits
A device the size of a memory stick mimics a trusted keyboard and executes pre-programmed keystroke injection in under three seconds. Your endpoint protection treats it as a legitimate human interface device. No malware signature. No file download. No alert.
Rogue Network Implants
Small hardware devices placed behind desks or inside ceiling voids create persistent out-of-band backdoors. They bridge air-gapped segments, exfiltrate data over cellular or Wi-Fi, and survive reboots and re-imaging because they sit on the physical infrastructure, not the host.
Smart Building Lateral Movement
HVAC controllers and IoT sensors often share network segments with corporate infrastructure. An attacker who compromises a thermostat on a flat network can pivot into your production VLAN. The building thinks it is managing climate; the attacker is moving laterally.
THE PASM FRAMEWORK
Zero-Trust Extended to Physical Infrastructure
The PASM framework applies the same trust-nothing principle your network team already understands, but at the physical layer. Every port, every peripheral, and every cable path must be verified, monitored, and controlled.
802.1X Port Authentication
Enforcement of 802.1X network access control at every physical port. Unauthenticated devices are refused network access at the switch level, regardless of physical connectivity.
MAC Anomaly Monitoring
Continuous monitoring of MAC address patterns across your switching infrastructure. New, spoofed, or unexpected addresses trigger alerts that feed directly into your SOC workflow.
Physical Port Lockdowns
Unused Ethernet and USB ports are physically secured with tamper-evident locks. Active ports are documented, mapped, and assigned to specific devices. Any change to that mapping is flagged.
Peripheral Hardening
Printers, badge readers, VoIP handsets, and shared peripherals are audited for default credentials, open management interfaces, and unpatched firmware. These devices are often the weakest link on a hardened network.
Tamper-Evident Sealing
Critical cable runs, patch panels, and network closets receive tamper-evident seals. Physical inspection schedules ensure that any breach of the seal is detected and investigated.
SIEM/SOAR Integration
Physical security telemetry is formatted for ingestion by Splunk, Microsoft Sentinel, and other SIEM/SOAR platforms. Port authentication failures, peripheral connection events, and tamper alerts correlate with your existing network security data.
DELIVERABLES
What You Get
Every engagement produces actionable documentation your security team and network architects can implement immediately.
Edge-Device Audit Report
Complete inventory of every device connected to your physical infrastructure, classified by risk tier. Includes rogue device findings, default credential exposures, and firmware vulnerability assessments.
Port Vulnerability Map
Floor-by-floor map of every exposed Ethernet and USB port, annotated with authentication status, physical accessibility, and recommended controls. Designed for direct handoff to network operations.
Physical DLP Policy Template
Ready-to-adopt Physical Data Loss Prevention policy covering peripheral access controls, removable media governance, port usage protocols, and visitor device restrictions. Mapped to ISO 27001 and NIST 800-53 PE controls.
SIEM Integration Specifications
Technical specifications for feeding physical security events into your SIEM. Includes log format definitions, correlation rule templates, and alert threshold recommendations for Splunk and Microsoft Sentinel.
RELATED SERVICES
Complementary Assessments
Physical Security Assessments
Broader facility-level vulnerability reviews covering access control, acoustic leakage, sight-line exposure, and visitor flow.
TSCM Counter-Surveillance
Electronic sweep services for detecting covert surveillance devices and rogue transmitters. Essential when hardware implant detection extends beyond network devices.
HARD QUESTIONS
The objections we hear. The answers we give.
Why do we need ‘Physical DLP’ if we already use network-level Access Control (NAC) and software Endpoint Protection (EDR)?
Software-based security has blind spots. EDR cannot stop a malicious insider from taking a physical photo of a screen, using a specialised hardware keylogger, or exploiting a rogue local access point before the network can isolate it. We do not replace your software stack. We bridge the gap. Our tools output standard telemetry logs that feed directly into your existing SIEM/SOAR platforms, strengthening your existing Zero Trust architecture without adding agent bloat.
A mature Zero Trust network blocks unapproved script executions. Why should I pay to physically harden ports?
Advanced out-of-band hardware attacks can mimic authorised system assets (like corporate keyboards or charging cables) to bypass standard software policies. While our core catalogue includes physical port blockers and tamper seals, we customise our approach to your current digital posture. If your software policies are exceptionally tight, we shift our focus away from endpoints and toward protecting exposed infrastructure points, like drop-ceiling network runs and server closets.
Most of our data lives in the cloud and employees work remotely. How do you protect data outside the office?
The physical attack surface moves wherever your employees go. Our enterprise framework extends beyond corporate walls. We provide out-of-the-box physical security playbooks for remote executives and high-risk travellers, while tailoring custom proximity rules for shared co-working spaces and off-site operations.
