The global Session Border Controllers market is projected to grow significantly, from 838.0 million in 2025 to 1,886.0 million by 2035 an it is reflecting a strong CAGR of 8.2%.
Organizations are looking for secure and seamless SIP-based communication, and this is the reason why the Session Border Controllers (SBC) market is growing. SBCs and associated services are designed to handle security features, interoperability, and policy enforcement across VoIP networks. Both SBC solutions and services provide features (encryption, call routing, and denial-of-service (DoS) protection), but services assist businesses with things like deployment, maintenance, and compliance management. The continued adoption of cloud-based communications and SIP trunking is generating demand, both for SBC hardware and managed services.
Adoption by enterprise size: Another example of enterprise adoption details is that large enterprises have high call volumes, multiple sites and are subject to compliance pressures, which leads to significant use of SBCs. These businesses use SBC with UC platforms and cloud infrastructure to protect their channels of communication. Conversely, SMEs are migrating over to hosted SBC solutions in the cloud so as to minimize infrastructure costs while maintaining secure VoIP communication. The demand for cost-effective, scalable SBC services is increasing market growth across all sizes of businesses.
SBCs are universally used to secure and optimize network traffic, preventing toll fraud, ensuring top-notch service quality for other service providers and industries. Introduction As enterprises increasingly migrate their contact centers to the cloud, session border controllers (SBCs) will need to act as the gatekeepers for security and regulatory compliance related to voice traffic. Moreover, enterprises and corporates launching VoIP, UC, and cloud collaboration tools rely on SBCs to protect from security loopholes and services downtimes.
Regulatory compliance remains a key driver of the market, as changing telecom laws like FCC regulations in the USA or GDPR in Europe must be adhered to with secure call handling, encryption, and lawful interception. BFSI and healthcare enterprises, as well as government agencies, with high compliance requirements need advanced SBC solutions to secure sensitive communications without compromising compliance mandate. Comparative to the leading SBC market, North America dominates due to its strict regulatory policies, high adoption of VoIP, and strong cybersecurity focus, along with the presence of major solution providers in this market.
On the other hand, in emerging markets like India and Australia, growing telecom infrastructures, escalating cloud communication activities, as well as regulatory oversight in digital economies are encouraging the adoption of SBCs in these regions.

Rising VoIP and SIP adoption drives demand for secure and efficient communication networks
With the future in global communications leaning towards Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) technologies, telecommunications infrastructures have undergone a sea change. According to research on VoIP service market, in 2023 the global VoIP services market was worth roughly USD112.9 billion, with a projected value of USD263.0 billion by 2032, signifying a compound annual growth rate (CAGR) of 9.6%. SIP and VoIP solutions are cost-effective, scalable, and seamless to integrate, so this boom comes as no surprise.
But the move to IP-based communications brings its own challenges in areas such as security and network management. This challenge has led to the development of Session Border Controllers (SBCs) as critical devices for overcoming these challenges, which provide excellent security features such as encryption, authentication, and fraud prevention.
Governments have previously recognized the need for secured VoIP communications, and the Federal Communications Commission (FCC), for example, has issued compulsory guidelines for the rapid provisioning of VoIP 911 services, enabling IP-based Emergency Networks to be made adequately and adequately secure. As more companies embrace VoIP and SIP solutions, the need for SBCs will grow, keeping communication networks secure and effective.
Expansion of Unified Communications (UC) platforms requires secure SIP connectivity
Unified communications (UC) platforms combine multiple communication tools (like voice, video, messaging and collaboration) into a unified system to boost organization efficiency. Session Initiation Protocol (SIP) serves as the backbone of many UC solutions by enabling the initialization, maintenance, and teardown of real-time sessions.
The growing adoption of UC platforms by businesses to enhance efficiency has created a need for secure SIP connectivity. In this context, Session Border Controllers (SBCs) become key by managing SIP traffic, securing it from attacks such as denial-of-service attacks or eavesdropping and allowing interoperability between non-homogeneous systems.
The worldwide SBC market is projected to expand from roughly USD1.2 billion in 2023 to USD2.8 billion by 2032, at a CAGR of 9.8%. This growth is fueled by the increasing implementation of UC platforms across industries. And government agencies, many of which have discovered advantages in integrated communication systems, are implementing UC solutions as well.
The Pentagon, for instance, has detailed plans for private 5G networks that enable next-gen UC and are key to making them secure and interoperable. The role of SBCs will be increasingly important to facilitate secure and efficient SIP connectivity as UC platforms become more prevalent.
Growing demand for 5G-compatible SBCs to support high-speed and low-latency communication
The arrival of 5G technology, there are going to be enviable improvements in communication speeds and latency that will change so many industries and their respective processes. To realize the full potential of 5G, network elements, including Session Border Controllers (SBCs), must be 5G-compliant. Specialized 5G data center-ready embedded and box top computers (SBCs) allow you to deal with high-power data throughput and low-latency processing for mission-critical applications such as telemedicine, autonomous vehicles, and augmented reality.
These SBCs secure session management across complex 5G architectures, including network slicing and edge computing environments, and provide a foundation for 5G mobile services. Secure 5G ecosystems are actively enabled by government initiatives. For example, The Department of Defense has published a strategy supporting the utilization of commercial private 5G networks on military installations and calls for the adoption of Open Radio Access Network (RAN) solutions to improve security and performance.
High implementation costs hinder adoption, especially for small and medium enterprises
The evolution towards direct cloud communication is transforming enterprise voice and the transmission of data, decreasing dependency on conventional SBC architectures. Cloud-based solutions have many organizations migrating from on-premise SBCs to SBCs built into cloud- based communication platforms that provide traffic management, security, and scaling capabilities. UCaaS and CPaaS cloud service providers deliver a voice and video calling with end-to-end encryption, obviating the need for additional SBC infrastructure.
Furthermore, direct cloud peering is growing among MSO and enterprise-level telecom operators with VoIP and SIP trunking services directly connecting to cloud-hosted applications, thus avoiding conventional SBCs. Increasing demand for software-defined networking (SDN) and cloud-native architectures enabling increased flexibility and automation in transport of voice traffic is driving this transition.
Organizations that are using Microsoft Teams Direct Routing, Zoom Phone, and Google Voice are increasingly selecting direct cloud connectivity instead of deploy an SBC for SIP-based communications.
