NSI specialises in Technical Surveillance Counter Measures (TSCM) using the most advance and up to date equipment available on the market to protect our clients. TSCM; also known as electronic bug detection, bug sweeping or counter surveillance; is the method of electronically and physically inspecting offices, buildings, vehicles, telephone systems, network systems and cabling for the existence of eavesdropping listening devices in all areas of Sydney, Chatswood, Parramatta, NSW and Australia.

Our equipment is second to none, using the most technologically advanced hardware and software available globally and methods perfected through years of experience within counter surveillance bug and camera detection.

Unlike our competitors, we provide detailed risk analysis and assessments, offer recommendations and take logical steps to secure your interests and offer services such as the installation of CCTV surveillance camera systems, back to base alarms or TSCM monitoring. To certify ongoing security, most corporate clients arrange regular inspections, usually every 4 to 6 months, or during times of particularly sensitive business activity; and our private clientele schedule inspections every 6 to 10 months when needed.

Corporate, Industrial and Political Espionage is on the rise. Protect your assets and business secrets sooner rather than later.

Do you feel you or your business are targets?

What should you do if you believe there is an eavesdropping device at your workplace or premises?

Call us from a safe location, i.e. a phone box or mobile phone away from the potential threat. Try to avoid significant discussions in the surrounding area until we are able to confirm the room or phone line is safe. Our experienced operatives will arrange a private meeting and examine how we will be able to aid you with your risk.

Successful detection programs can help find and prevent acts of spying, intimidation, blackmail, hostage taking and an assortment of other serious crimes. We can also provide anti surveillance guidance and support to identify covert attempts to observe corporate, executive or family activities.


Are you bugged?

Electronic bugs, listening devices, hidden cameras, infra red beams, burst/packet bugs, spread spectrum and other similar eavesdropping devices are widely obtainable over the internet and in many cases, easily installed. Our technical and physical inspections are complex and precise, providing a high-level service to governments, corporations, executives and individuals alike, using advanced counter surveillance equipment, procedures and policies to secure your privacy.

The protection of delicate information is a job for an expert and should not be taken lightly. The threat is rising rapidly as the complexity of covert equipment and techniques means that the need for security protection and understanding is now escalating. Business secrets can be stolen by competitors and offices are the likely target. Homes can also be the target of listening devices that can be used by criminals for extortion and theft. Other target areas include vehicle's that can be tracked by GPS trackers and hotel rooms where private meetings may be held.

NSI provides guidance and assistance on security processes that can be undertaken to decrease the probability of you or your company becoming the objective of political, corporate or industrial spying throughout Sydney. We have packages to suit your budget and for corporate clientele we have great rates for TSCM surveys and ongoing TSCM sweeps. NSI can also perform technical assessments and provide advice to improve security within your workplace or home, and provide a unique TSCM monitoring service.

Online Cyber Investigations

Online security, cyber crime and mobile phone espionage are the biggest threats to hit Australian businesses and government organisations. Companies should invest in cybersecurity counter measures as all sectors are at rist of data theft. This includes individuals. Our trained operatives are IT professionals and are able to detect keylogging devices, network vulnerabilities, malware, spyware, botnets and viruses.

As for mobile phones, spy software is widely available. Security measures should be in place such as passwords and lock codes. Staff should not leave their phone accessible to others as mobile phones thesedays are connected to the internet and in more and more cases, to company networks, thus allowing an intruder easy access to company files.
