The Future of Session Border Controllers – Trends and Predictions


Two decades back, nobody in the market knew about SBCs. But fast forward to today, SBCs are one of the most important technologies worldwide. What started as a perimeter security element has now become the central switching element at the core of many networks. Also known as border elements, VoIP Gateways or simply gateways, the expansion in the role of Session Border Controllers has brought in several new trends that we are witnessing today.

Session Border Controller Market – Ongoing Trends

Let us take a look at some of the most popular trends that are paving the path for session border controllers:

More Inclination towards Security

Security and privacy have become the primary focus for enterprises all around the world. With the high vulnerability of IP communication channels to cyber-security threats, more and more sophisticated SIP attacks are happening everyday such as distributed denial of service attacks, toll fraud, etc. The need to deploy advanced safety and security measures is also growing.

Session border controllers (SBCs) are used to secure and manage VoIP (Voice over Internet Protocol) and other real-time communications sessions at the network edge. They act as a security gateway between the enterprise’s internal network and the public internet, protecting against various security threats such as Denial of Service (DoS) attacks, toll fraud and unauthorized access to the network.

Session Border Controllers empower enterprises to have advanced level control over their VoIP environments. This also helps them safeguard their revenue and productivity from getting impacted.

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

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 in managing the growing SIP traffic by providing them 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 significant rise in the demand of SBCs.
