Ought to deliver the best solution to the consumer’s security issues we are proud to say we have done a commendable contribution to the industries we are serving.

Where We Started ?

Sterna Security was started in 1996 by Mr.N.Rangaswamy who also wears the mantle of the Chief executive and President who promotes the company. The company is a part of Ramalingam & Co group that has its origins in 1927. Started as a primarily trading unit in printing & packaging paper, this unit has since diversified and over the years evolved as a marketing outfit with the focus on niche markets and solutions. The origin of sterna security was with Abloy in 1996. Being a proud partner of Abloy, we have integrated electromechanical products that are of high security standards. The first security solution developed by us brought accolades as we solved one of India’s biggest problems faced by petroleum industry. The petroleum industry over the years has been plagued by threats of adulteration and pilferage. Ensuring products was delivered in right quality and quantity was a challenge. We developed the first solution ever that solved this very problem and helped petroleum companies delivered quality and quantity and ensuring purity during transportation of products. Since then we have had the privilege of providing solutions to some of the best companies in the world of Oil & Gas, Telecom, Infrastructure and Security.


Design and development is the main core in this part of the organization. Our all security products are made and developed from an idea in this part of our firm only. Be it the software or electromechanical product, they are modeled and made into a prototype for manufacturing by employees working here.


Products designed here at sterna security not only enables the clients to solve their complex scenario but also makes it easy for them to get it delivered at highest precision. This phase is for detailing the design and creating engineering drawings and documents of the design presented during the prototype modeling. Any changes or modifications to the design requested by the customer are incorporated before drawings are made. A written report is also delivered detailing everything done in this phase. Again, at the end of this phase we will update the proposal and give firm costs for the next phase before proceeding for development.


Once the design is finalized a prototype is made and check for testing.The testing can be as simple as "does it work or not?" but with more intricate assemblies this can become much more complicated as you are not just testing if it works but how well or how long it works. Tests vary tremendously on the type of product and level of quality the customer wants to achieve. These can also involve market research testing to see how well the product would be received and for production. The amount of testing is most often limited by time and budget constraints.

Often the product development cycle listed above is repeated several times mainly to iron out bugs or fix problems that were discovered in testing. The goal is usually to create a short run of prototypes that are as close to release as possible and get them into the hands of key testers, select customers or others to do some final testing before a full product is released. The release build phase is usually just to get the final bugs out of the design as production is ramped up for the initial product development.


Manufacturing and assembly is the main core in this part of the organization. Our all security products are manufactured and assembled in this part of our firm only. After a prototype is made after from a development phase, production is done in sterna security devices.


Prototype Testing is done before manufacturing.Once drawings and necessary documents are completed, these are sent out to manufacturing houses for quote so that the customer will have a detailed price for the building of the product. At the end of this phase the work is summarized and delivered to the customer at a Critical Design Review (CDR).

Design for Manufacturability and Integrated Product Development may require additional effort early in the design process. Manufacturing costs depend on complexity of our product, if there are multiple components, material selection, low batch product or high batch numbers. These factors are considered to ensure that company will make a healthy profit on the end product.


The assembly of product is vital. It is assembled with minimum number of joins and hence this will not only spend up manufacture and reduce manufacturing costs it also makes assembly of our product quicker. So the overall cost of our product is considerably less than a complex product.

Our company utilizes assembly processes such as manual, semi-automatic and fully automated assembly techniques ranging from automatic contact insertion and final assembly for connectors and smaller automotive components. In addition to our product assembly services for electro-mechanical components , we provide customers products in a variety of packaging solutions including tape and reel packaging meet each customer's needs to reduce costs during the next levels of assembly for smaller components.


Integration and Servicing is the main core in this part of the organization. Our all security products are installed and serviced in this part of our firm only. After a product is installed in the client side, any complaints and support are handled by Nana Foundation.


Installation of the products will be done by our company employee under professional guidance. Installation of equipment in the industrial environment is handled by professionals working under Nana Foundation. So once they are installed in the destination, they are integrated to the server under which the electromechanical device operates.

Application Integration services focus on the clients' strategy, operations, people and information management.

Unlock The Door To The Mobile Era

When the system administrator changes an employee's access rights, the employee can update their smart key with the new rights through their smartphone. This makes updating quick, easy and efficient, which saves both time and money. In order to maximise security, the key's unlocking rights can be verified every time the lock is opened. Unlocking rights are downloaded to the key through a smartphone, and they are valid only until the lock has been opened. This way, a lost key is no longer a security risk.

Double-Secured Security

The patented PROTEC2, based on a rotating disc cylinder, ensures the mechanical locking. The electronic CLIQ™ technology enables flexible management of keys, access rights and the access register. PROTEC2 and CLIQ™ work together seamlessly. Data transfers between the different parts of the system are strongly encrypted.

Individual Access Rights

One key is enough for each employee – your own or subcontractors’ – as it has individual access rights to the necessary premises. The validity of the access rights can be determined as desired, for example for one day or for only five minutes. After the period of validity has ended, a lost key is not a security risk. If a mobile solution is connected to the system, the unlocking rights can be verified and updated whenever a lock is opened.

Easy To Use And Manage

Administration – for example, changing access rights or removing a lost key from use – is done via the CLIQ™ Web Manager web app. If a mobile solution is linked to the system, employees can update changes made by the administrator to their keys with the help of a smartphone, anywhere and everywhere. Otherwise, the updating can be done through a wall unit. The system enables a real-time access register, which can be utilised in resource management, for example. If you desire, Abloy can manage the software and locking system updates related to the system as well as the server room.

Master Key System

Careful planning is the basis for long-term success of the master key system, ensuring the customers safety and security. It is possible to create multi-level master key systems each with unique access rights for different user groups.
