CEO's Message

In this ever more connected world, innovation is coming less from inside large corporations. Increasingly it is generated across agile ecosystems of companies of all types and sizes. Business and industry boundaries are becoming blurred as a result, and this is disrupting the way that companies traditionally operate. The security industry is no exception.

Today, new technology like AI is opening up new possibilities for what businesses can achieve. As IoTs, sensors and ever more potent cyber physical systems multiply in the very fabrics of our future smart cities and buildings, the scope and intensity of cyber risks stemming from smart building technologies can be expected to increase exponentially in the future. Such threats should be clearly identified, assessed and made known to potential users and owners of smart buildings. Traditionally trusted fire and security systems are clearly not enough anymore.

Mobile connectivity has changed the way we live, work and play. From smartphones to wearables and tablets, mobile devices are ever present in today's environment. The flip-side of this technological boom is the sacrifices made towards our privacy. Today, maintaining privacy of sensitive identity data is more important than ever. Security on its whole has to be looked at from different and diversed angles today. We at ASN are conscious of these, and are constantly re-skilling and up-skilling ourselves to be one step ahead, always.

Our purpose is to realize a safer, more prosperous society where people are empowered by technology but not at the expense of compromising security. And we always believe that to get the best outcomes, we must put people at the center of the eco-system. It has to be a human centric intelligent society. It is one thing to set out on an ambitious vision, but we recognize we cannot do this alone. That is why collaboration has always been at the heart of our approach. We believe that working together with our customers and partners is our topmost priority.

As digital technology comes to dominate our world more and more, we believe that by working together and making the right choices, we really can make a positive difference to the security industry, and society as a whole. This reflects our strong commitment to delivering positive outcomes together with our customers and partners. 

To quote the late founder and Managing Director of our company. the security industry legend, Mr. Thangaratnam Rengasamy:


Through co-creation, we will continue to work to realize a safer, secured and more sustainable society.

Uniformed Security

We live in an unpredictable world, where security threats confront us on a routine basis. When these situations become a dangerous and volatile environment, few things are more reassuring than the sight of uniformed security officers patrolling the vicinity. Uniformed officers can provide an immediate sense of stability. However, we know it’s not enough to simply have uniformed individuals walking around looking tough. It’s vital that these security guards be seasoned professionals, highly trained in the latest methods of crisis management. That’s the high level of uniformed security that we are proud to provide at ASN.

Security Audit & Survey

Like the name implies, this is a comprehensive physical inspection and evaluation of every aspect of your security system, its controls, and their parameters throughout your space or facility. This is done on both an individual and a macro level, giving you the intel you need to make better decisions about how to run your facility. Generally, the physical security risk assessment is the combined process of both practicing an intensive audit and analyzing the results that come from it, which pertains to the entire physical security system of a particular building. In order to make sure you’re going about it correctly, use these tips to keep your space safer from harm.

Physical security audits can uncover numerous problems associated with your system or your procedures. A robust security system may include numerous security controls, such as human guards, physical locks, intelligent locks, fences, a CCTV system, proper lighting and alarms, among other components. Conducting a physical security audit shows you exactly what the security gaps in your facility are, which might mean that you have to invest in more equipment or better operational guidelines.

Private Investigation

Private investigator services we offer include surveillance, background checks, infidelity, fraud, and information gathering services.

Every case we undertake is treated with the utmost of sensitivity and confidentiality. We appreciate that you are sharing your most private and sensitive matters with us and therefore we GUARANTEE every client full confidentiality and discretion. As no two cases are ever the same, we would always recommend that you take advantage of our free consultation and speak with our highly experienced and qualified private investigators as we can advise you of the best way forward to obtain the intelligence you need or achieve your objective.
