Why Integrating Private 5G Security Into Enterprises Is Critical for the Next Wave of Digital Transformation

According to TechForge Media, the adoption of Private 5G (P5G) networks is ushering in unparalleled opportunities for industries undergoing digital transformation. However, the integration of P5G into existing enterprise IT security frameworks poses significant challenges, as cellular standards and traditional IT systems require a common security framework to prevent vulnerabilities.

Why the Integration of Private 5G and IT is a Security Priority

Private 5G aims to deliver high performance across use cases like real-time tracking, automation, and predictive maintenance. As highlighted by a recent Wireless Broadband Alliance (WBA) report, P5G creates new attack surfaces, which could expose enterprises to cyber threats if not managed properly. Enterprises adopting P5G must navigate the complexities of 3GPP standards that diverge significantly from existing Wi-Fi and Ethernet protocols.

P5G networks authenticate using SIM cards, which traditionally grant broad access within mobile frameworks. Without integration into enterprise IT access controllers, connected devices such as industrial robots can operate outside the radar of corporate SOCs (Security Operations Centres), increasing risks of unauthorized access or lateral cyberattacks.

Tiago Rodrigues, CEO of WBA, noted, “Private 5G represents the next frontier of enterprise connectivity, but with its potential comes new complexity and risk. By bringing Wi-Fi and 5G under a common security framework, the industry can accelerate digital transformation without compromising resilience or interoperability.”

Market Context: P5G’s Role Amid Industry Trends

The rise of digital transformation in sectors such as logistics, manufacturing, and healthcare highlights the critical role of P5G. Market drivers include low-latency performance essential for edge computing and increased support for Industry 4.0 initiatives. According to recent industry data, the global private 5G market is projected to exceed $10 billion by 2028, growing at a CAGR of 23.4% from 2023. Organizations that fail to address the security challenges of P5G risk falling behind in this competitive landscape.

Competitors such as Wi-Fi 6/6E remain strong challengers to P5G’s adoption, especially in enterprises prioritizing traditional access frameworks with robust role-based access control. However, the convergence of Wi-Fi and P5G, equipped under unified security governance, is being touted as the true future-proof strategy for global enterprises aiming to leverage multiple access technologies simultaneously.

The Way Forward: Expert Insights and Best Practices

Industry experts emphasize the importance of implementing Zero Trust principles in P5G deployments. By assuming no implicit trust, whether based on device type or access medium, organizations can prioritize continuous verification to secure critical operations. Micro-segmentation, which creates granular access policies tied to device roles rather than IP addresses, is positioned as a vital enabler in securing dynamic P5G use cases.

Key recommendations from the WBA include:

• Mapping assets and endpoints to monitor connected devices within the P5G network.
• Deploying role-based access controls to avoid unrestricted lateral movements.
• Implementing AI-focused monitoring tools for anomaly detection in real-time traffic.
• Utilizing standard REST APIs and protocols to unify 5G core networks with enterprise IT systems.

Moreover, the integration of multi-access edge computing (MEC) with P5G is expected to further enhance security by keeping data processing localized. For industries that handle highly sensitive or regulated information, such as manufacturing designs or patient records, this reduces exposure risks and ensures compliance with privacy standards.

Final Thoughts

As Private 5G networks continue to reshape enterprise connectivity, the importance of developing converged security architectures cannot be overstated. By aligning cellular protocols with enterprise IT frameworks, businesses can unlock robust digital transformation without these advancements becoming liability threats.
