SEPP Interconnect Security Market Report 2026

The sepp interconnect security market size has grown exponentially in recent years. It will grow from $1.4 billion in 2025 to $1.7 billion in 2026 at a compound annual growth rate (CAGR) of 21.6%. The growth in the historic period can be attributed to growth in mobile data traffic, expansion of LTE roaming networks, rising inter operator signaling risks, historic telecom fraud incidents, increasing cross border network connections.

The sepp interconnect security market size is expected to see exponential growth in the next few years. It will grow to $3.75 billion in 2030 at a compound annual growth rate (CAGR) of 21.8%. The growth in the forecast period can be attributed to global 5g standalone rollout, rising cross operator data exchange, stricter telecom security regulations, increasing edge network complexity, higher demand for secure roaming frameworks. Major trends in the forecast period include 5g interconnect security gateways, encrypted roaming data exchange, policy driven inter operator security, real time interconnect threat monitoring, software defined edge security platforms.

The expanding deployment of 5G standalone networks is expected to stimulate the growth of the security edge protection proxy (SEPP) interconnect security market in the coming years. A 5G standalone network is an independent 5G architecture built on a dedicated 5G core network that delivers end-to-end 5G services without reliance on 4G infrastructure, enabling ultra-low latency, network slicing, and advanced capabilities. The rollout of 5G standalone networks is accelerating due to rising demand for ultra-low latency applications such as autonomous systems, smart cities, and industrial automation. SEPP interconnect security supports 5G standalone network deployment by securing signaling, safeguarding inter-network data exchange, and enabling trusted connectivity between operators. For example, in December 2024, according to the Office of Communications (Ofcom), a UK-based communications regulator, active 5G standalone sites in the UK increased from about 2,000 in 2023 to nearly 3,300 in 2024, demonstrating strong year-over-year growth. Therefore, the expanding deployment of 5G standalone networks is advancing the growth of the SEPP interconnect security market.

Leading companies operating in the SEPP interconnect security market are emphasizing the development of advanced 5G roaming-based security enhancements to ensure secure and standards-compliant cross-network communication. 5G roaming-based security enhancements are dynamic protective measures activated when users or devices connect to external 5G networks while roaming, ensuring data protection and network integrity through continuous authentication updates, threat monitoring, and enforcement of security policies across both home and visited networks. For example, in March 2025, IPLOOK Technologies Co., Ltd., a Hong Kong-based telecom solutions provider, released an upgraded Security Edge Protection Proxy (SEPP) solution featuring improved N32 interface performance, optimized TLS handshake processes for faster inter-operator connectivity, dual routing mechanisms for complex roaming scenarios, and advanced threat defense capabilities such as intelligent topology concealment and anomaly detection. These upgrades align with 3GPP Release 17 standards to support secure and efficient interconnect signaling within 5G roaming architectures. The scalable architecture supports up to 200,000 transactions per second in clustered deployments and assists operators in lowering security operation costs while maintaining compliance across interfaces including N8, N12, N14, N16, and N27.

In October 2023, TOMIA, a US-based provider of roaming and interconnect monetization solutions, partnered with Cumucore to enhance secure interconnect signaling. This collaboration aims to support seamless and secure 5G standalone roaming interoperability for mobile operators through SEPP-to-SEPP integration. Cumucore is a Finland-based company delivering 5G core software solutions with built-in SEPP functionality for secure network signaling.

Major companies operating in the sepp interconnect security market are Deutsche Telekom AG, Huawei Technologies Co Ltd, Cisco Systems Inc, Oracle Corporation, Ericsson AB, Nokia Corporation, ZTE Corporation, Palo Alto Networks Inc., Amdocs Limited, F5 Inc, Mavenir Systems Inc, Ribbon Communications Inc, Mobileum Inc, Belgacom International Carrier Services SA, iBASIS Inc, Enea AB, IPLOOK Network Co Ltd, teleSys Communications Inc, Cumucore Oy, BroadForward BV, TOMIA sro, and Nomios Group BV.

Tariffs on telecom security hardware, encryption appliances, and specialized network processors are increasing deployment costs in the SEPP interconnect security market. Import duties on secure gateways and edge security modules are affecting hardware heavy segments most directly. Telecom operators in regions reliant on imported network security equipment, especially in parts of Asia and Latin America, are seeing higher capital expenditure. Some projects are being re scoped due to equipment pricing shifts. Vendors are expanding local manufacturing and regional integration partnerships. Certain tariffs are encouraging domestic telecom security product development. This is gradually strengthening local supply capability and vendor diversity.

Security edge protection proxy (SEPP) interconnect security is a network security function used within mobile and telecommunications networks, particularly in fifth-generation (5G) architecture. It serves as a secure gateway between network operators to protect the exchange of signaling and control information across network borders. It safeguards inter-operator communication from cyber threats, unauthorized access, and data manipulation while ensuring confidentiality and integrity.

The primary components of security edge protection proxy interconnect security include software, hardware, and services. Software refers to systems that protect interconnection traffic at network edges by enforcing security policies and mitigating threats across connected networks. These solutions are deployed through cloud-based and on-premises models based on infrastructure and scalability requirements and are adopted by small and medium enterprises as well as large organizations. The end users include telecommunications operators, enterprises, managed service providers, and others.

The security edge protection proxy (SEPP) interconnect security market consists of revenues earned by entities by providing services such as threat monitoring and detection, policy configuration and enforcement, secure roaming management, vulnerability assessment and mitigation, compliance auditing and reporting, and managed edge security support services. The market value includes the value of related goods sold by the service provider or included within the service offering. The security edge protection proxy (SEPP) interconnect security market also includes sales of edge security gateways, encryption modules, network access control devices, secure routing and switching equipment, software-defined security platforms, and interconnect monitoring and analytics tools. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD unless otherwise specified).
