Securing Sensitive Spaces: AMBICO’s Acoustic & Radio Frequency Doors & Frames


Written by Adrian Coughtry at AMBICO Limited

In the rapidly evolving landscape of global security, threats like cyber espionage and electronic eavesdropping have underscored the critical need for fortified environments. AMBICO Limited has risen to this challenge, emerging as a pioneer in the development of acoustic and radio frequency (RF) resistant door and frame assemblies. Our products stand as comprehensive solutions, meticulously engineered to safeguard the most sensitive spaces against a myriad of threats, ensuring the protection of critical information and infrastructure.

The Necessity of advanced security measures

In an era where digital and physical security converge, the demand for specialized security features has escalated. Consider the acoustic resistant doors installed within RCMP stations across western Canada, which are not merely doors but sentinels of privacy. In interrogation rooms and strategic meeting spaces, they maintain the confidentiality of sensitive dialogues, preserving the integrity of investigations and protecting confidential information.

Complementing our acoustic resistant doors are RF-resistant doors, designed to block electromagnetic signals. This is paramount in shielding electronic equipment and data from external interference, a prevalent concern in the digital age. Whether it’s safeguarding a server room, a data centre, or a state-of-the-art laboratory, these doors act as a bulwark against electromagnetic interference (EMI), reinforcing cybersecurity measures and averting data theft or espionage.

Securing sensitive information: The rise of SCIF standards in Canada

In today’s digital age, protecting sensitive information is paramount. This has led to the growing demand for Secure Compartmented Information Facilities (SCIFs) and SCIF-like standards across Canada, mirroring global trends in heightened security measures.

What are SCIFs?

SCIFs are specialized facilities designed to provide a secure environment for handling classified and sensitive information. They utilize advanced technologies, such as acoustic and radio frequency (RF) shielding, to prevent unauthorized access and electronic surveillance.

Canadian adoption

In Canada, the adoption of SCIF standards is on the rise. Government agencies, defence contractors, financial institutions, and research organizations are among those investing in SCIFs to protect sensitive data. The Canadian Centre for Cyber Security, in its Cyber Threat Assessment 2023-2024 report, highlighted the growing threat of cyber espionage, reinforcing the need for robust security measures like SCIFs. Additionally, the Department of National Defence (DND) announced that it would acquire deployable Temporary SCIFs (TSCIF) and Semi-Permanent SCIFs (SPSCIF), accredited for Top Secret material, to enable Royal Canadian Air Force to carry out operations both domestically and abroad.

Essential protection for military assets and digital infrastructure

The acquisition of 88 Lockheed Martin F-35 fighters by Canada, set to begin delivery in 2026, underscores the country’s commitment to enhancing its air defence capabilities. This strategic move, representing a $19 billion investment, aims to replace the CF-18 fleet. This will ensure Canada’s air force is equipped with advanced operational capabilities by 2032-2034. These state-of-the-art jets offer superior intelligence, surveillance, and reconnaissance capabilities, essential for addressing contemporary security challenges.

In this context, the security of both the jets and their associated advanced training simulator facilities becomes paramount. Acoustic and RF-resistant doors play a critical role in safeguarding these vital assets against espionage and electronic surveillance. Such security measures are essential not just for protecting the physical aircraft but also for securing the simulator facilities where pilots receive their training. These facilities contain sensitive information and technology that, if compromised, could undermine Canada’s military assets’ operational integrity and readiness. For these reasons, incorporating robust security solutions such as those provided by AMBICO Limited into these environments is crucial to maintaining national defence and maintaining military operations’ confidentiality and integrity.

AMBICO’s acoustic and RF doors are crucial in sectors like telecommunications, data centres, research facilities, and financial institutions, where they shield against Electromagnetic Interference (EMI) and enhance security. These doors protect the infrastructure that supports digital communications, stores vast data volumes, conducts sensitive research, and manages financial transactions. They prevent unauthorized access and provide protection against cyber and physical threats. 

By meeting industry standards and collaborating with law enforcement, security experts, and the military, AMBICO ensures these sectors maintain the confidentiality, integrity, and availability of critical data and systems.
