Driving Forces Behind SBC Market Growth

Security of Business Communication Channels

VoIP offers greater scalability, flexibility, and cost-effectiveness as compared to traditional communication technologies. With these benefits, it has become one of the most preferred communication technologies among businesses. While its adoption is on a continuous rise, various security concerns among enterprises are also growing.

Due to this, the need to deploy session border controllers is also rising. It is because, primarily, SBCs function towards protecting and securing the network from hackers. SBCs work in real-time and upon detecting a potential threat, they immediately block it and raise an alert as well. Cyber threats such as DDoS attacks and toll frauds can easily attack IP communication channels but by deploying SBCs, companies can keep a check on such cyber threats.

Increased Focus on Customer Experience

Besides security, intelligent control is another USP offered by SBCs which helps businesses to obtain more control over their VoIP communication channels and achieve their customer experience goals. Through Intelligent Call Routing functionality, SBCs ensure that for every network, an optimal route is chosen to deliver a call to its final destination.

In other words, it makes sure that communication is provided via only the most advantageous channels so that each conversation properly reaches the intended person. Also, SBCs offer a number of features including advanced media processing capabilities, NAT Traversal, disaster recovery, etc. that improve the reliability, security, and quality of VoIP communications. This, in turn, boosts customer satisfaction and leads to better customer experience.

Rising Demand for BYOD

The workplace scenario has changed completely. It is more flexible and mobile than ever before. Employees can work from anywhere using any supporting device. Geographical boundaries have simply vanished. Now, with companies adopting BYOD strategies, the traffic from SIP communications is on a continuous rise.

Session Border Controllers can help companies manage the growing SIP traffic by providing them with the right set of tools. Session Border Controllers (SBCs) can support Bring Your Own Device (BYOD) by providing security and management for VoIP communications. SBCs can be placed at the border of a network to inspect and control SIP and other protocols used for VoIP. They can authenticate and authorize devices before allowing them to connect to the network, and can also encrypt and decrypt communications to ensure secure transmission. Additionally, SBCs can provide Quality of Service (QoS) management to ensure that BYOD devices receive adequate bandwidth for high-quality communications.

With all the above-mentioned trends, it is evident that there will be a significant rise in the demand for SBCs.

Challenges and Opportunities in the SBC Industry

The SBC industry is also not untouched by challenges. Some of the major factors that can hinder the growth of the global session border controller market are:

  • Interoperability i.e. SBCs’ ability to normalize different dialects of SIP signals to mitigate multi-vendor incompatibilities is quite complex and limits its implementation.
  • The setup installation and maintenance of SBCs require high technical expertise which also limits the growth of the market.
  • Poor implementation practices and complex configuration are also the drawbacks of SBCs.
  • Lack of awareness about the availability of session border controllers in the emerging global business market also hinders growth.
  • Availability of Open-source SBCs also inhibits the growth.

Here are some significant opportunities in the Global Session Border Controller Market:
