    Understanding COTS (Commercial off-the-shelf) in Cyber Security

    In today’s digital age, businesses are heavily reliant on technology to operate efficiently. Cybersecurity threats are a major concern for businesses, and it’s imperative to protect sensitive data and information from unauthorized access. One aspect of cybersecurity that businesses must consider is the use of Commercial off-the-shelf (COTS) solutions. COTS refers to hardware and software that is commercially available and not specifically built for any particular organization. In this article, we will explore the definition of COTS in cybersecurity, its advantages and disadvantages, and best practices for implementing COTS.

    The Definition of COTS in Cyber Security

    COTS in cybersecurity refers to the use of hardware and software that is readily available through commercial suppliers. These products are manufactured and produced on a large scale for a wide range of customers and are not customized for any specific organization. The National Institute of Standards and Technology (NIST) defines COTS as “hardware and software products that are sold in substantial quantities in the commercial marketplace, and that are widely available to the general public.” (NISTIR 7622)

    Examples of COTS products used in cybersecurity include antivirus software, firewalls, intrusion detection systems, and Virtual Private Network (VPN) software. By using COTS solutions, businesses can save time and money since they don’t have to develop, build, or test these products from scratch.

    Advantages and Disadvantages of COTS in Cyber Security


    • Ease of Deployment
    • COTS products are easy to deploy, configure, and maintain since they are designed for large-scale deployment.
    • Cost-Effective
    • COTS software and hardware are cheaper than building custom-made solutions since they are built to be sold in large quantities.
    • Faster Time to Market
    • COTS products are readily available in the market, which allows businesses to implement them quickly and start protecting their network.
    • Proven Track Record
    • COTS solutions have been tested by a wide range of customers and have a proven track record of effectiveness, reliability, and security.


    • Not Customizable
    • COTS products are not designed for a particular organization’s needs, which may result in businesses having to adapt their processes to fit the product.
    • Lack of Control
    • Since the product isn’t custom-made, the business has limited control over the functionality and security of the COTS product.
    • Dependency on the Vendor
    • Businesses depend on the vendor for support, maintenance, and upgrades to the COTS product.
    • Potential for Cybersecurity Vulnerabilities
    • COTS products may have known vulnerabilities that hackers can exploit since they are widely available and used by many businesses.

    COTS vs Custom-made Solutions in Cyber Security

    When it comes to cybersecurity, businesses have two options: use COTS solutions or build custom-made solutions. Both options have their advantages and disadvantages.

    Custom-made solutions are designed to fit a particular organization’s needs, which can result in a solution that is more secure and tailored to the business’s unique requirements. However, custom-made solutions are more expensive and time-consuming to develop, deploy, and maintain.

    COTS solutions, on the other hand, are cost-effective and easy to deploy. However, they may not fit the organization’s specific requirements and may have inherent security vulnerabilities that hackers can exploit.

    It’s essential to evaluate which option is best for your organization based on your budget, cybersecurity needs, and business requirements. In many cases, businesses choose to use a combination of both custom-made solutions and COTS products for optimal cybersecurity protection.
