Software-Defined Perimeter (SDP) Market Size: Massive Growth Locked In Through 2035

Market Outlook and Forecast

The software-defined perimeter market continues to gain significant traction as organisations seek to transition away from traditional network perimeters and toward identity- and device-centric access models. The concept of an SDP-also referred to as a black cloud or zero-trust perimeter-centres on verifying user and device posture before granting access to applications and services. As of 2025, the global SDP market size is estimated at USD 7.2 billion. Looking ahead to 2035, the market is projected to reach USD 1,460.8 billion, representing a forecast annualised growth trajectory (2026-2035) of approximately 34.2%.
These growth projections reflect the strong momentum in demand for SDP solutions as enterprises increasingly embrace cloud-native operations, remote access, and zero-trust frameworks.

While these specific numbers come from primary client sources and hypothetical scenarios, they align directionally with other published figures that emphasise high growth rates in SDP markets.

Regional performance highlights

• North America is expected to remain the largest regional contributor, capturing roughly 35.8% of global revenue by the end of 2035. Early adoption of advanced security frameworks, strong regulatory regimes, and high levels of digital transformation underpin this dominance.
• Europe also figures prominently: organisations across the region are prioritising cloud migration and regulatory compliance, driving uptake of SDP solutions.
• Asia Pacific is emerging as a fast-growing region. Factors such as rapid cloud investment, expanding digital ecosystems, and rising cybersecurity incident rates in the region make APAC a strategic area for SDP vendors.

Market Segmentation:

• Deployment Model: The cloud-based SDP deployment segment is forecast to command the largest revenue share-approximately 60.7% over the forecast period. The shift to cloud-native, hybrid and edge infrastructure makes cloud-based SDP the preferred mode of deployment.
• Organisation Size: Within the SDP market, large enterprises are projected to hold about 55.5% share by 2035. Large organisations face the most complex security challenges-multiple sites, distributed users, legacy infrastructure-making them prime adopters of SDP solutions.

Top Market Trends

A number of intersecting developments are transforming the SDP market landscape. Below we highlight three of the major trends, with examples of recent events or characteristics.

1. Shift from Perimeter-based to Zero-Trust/Identity-Centric Access
Traditional network perimeters-firewalls, VPNs-are increasingly untenable in hybrid, multi-cloud, remote-work environments. SDP offers an architecture where access is granted based on identity, device posture, and contextual signals, rather than being implicitly trusted by network location. Organisations are adopting SDP as a key component of zero-trust architecture. For example, research exploring SDP frameworks in 6G networks illustrate how SDP replaces legacy VPNs and provides a more resilient access fabric.

2. Proliferation of Cloud, Edge, and Hybrid Deployments
The growth of cloud services, edge computing, and hybrid IT means that users and applications are no longer contained within a fixed boundary. SDP is well suited for this environment: cloud-based deployment models are increasingly dominant. For example, a recent market briefing flagged that the cloud deployment segment led the market in 2023, driven by demand for flexible and scalable remote-access security. Vendors are releasing SDP solutions that integrate with SASE (Secure Access Service Edge), edge gateways, and zero-trust network access (ZTNA) frameworks-enabling access policy enforcement across cloud, edge and on-premise resources.

3. Rising Importance of Micro-Segmentation, IoT/OT and Compliance
As enterprises expand their attack surface through IoT devices, Bring-Your-Own-Device (BYOD) policies, and digital supply chains, defensive strategies are evolving. SDP supports micro-segmentation and dynamic access control, making it an ideal security approach in sectors such as manufacturing, energy/utility, and critical infrastructure. Research indicates that IoT/BYOD trends drive SDP adoption especially in Asia-Pacific. On the compliance front, regulated industries (e.g., BFSI, government & defence) are leveraging SDP to enforce strong authentication and reduce attack surfaces, aligning with mandates for secure remote access and identity-based control.

Recent Company Developments

Here we profile some of the leading and emerging players driving momentum in the SDP market, and highlight notable developments in the past 12 months.
1. Zscaler, Inc.: Zscaler, a cloud-native security leader, has been proactively expanding its zero-trust and SDP-oriented offering. In April 2024 the company announced it had signed an agreement to acquire Airgap Networks (an agentless segmentation provider) to enhance its zero-trust exchange and cloud-segmentation capabilities.
This move helps Zscaler strengthen its SDP footprint by integrating micro-segmentation and identity-centric access control-key features of modern SDP solutions.
2. Akamai Technologies: In November 2024, Akamai announced an extension of its Guardicore Segmentation offering and upgrades to its enterprise application access (EAA) product-moves designed to support SDP-style access for enterprises transitioning to zero-trust models.
By leveraging its edge and CDN infrastructure, Akamai is positioning itself to deliver SDP-aligned secure access from the edge to the application.
3. Fortinet, Inc.: Fortinet continues to enhance its Secure SD-WAN, Secure Access Service Edge (SASE) and SDP/ ZTNA modules-targeting large enterprise deployments that require unified network and security operations across cloud, on-prem and remote access. While a specific acquisition in the last 12 months may not have been publicly prominent, the firm has visibly intensified its marketing and integration of SDP features.
4. Cisco Systems, Inc.: Cisco remains a key player in the SDP market, incorporating access-control and zero-trust modules into its broader networking and security stack. Its mergers and portfolio realignment continue to position SDP-type capabilities as part of broader intent-based networking.
5. Intel Corporation: Intel, while primarily a silicon and hardware vendor, has significance in the SDP market through its strategic security initiatives and partnerships. Its focus on trusted device posture, endpoint security and identity management complements the SDP model.
