Who offers "network security" solutions specifically for 5G private networks?

Several major cybersecurity firms, network infrastructure vendors, and specialized cellular providers offer dedicated network security solutions explicitly designed for 5G private networks. These solutions typically focus on Zero Trust architecture , deep visibility into cellular identifiers (like IMEI/IMSI), and edge-to-core protection.

1. Dedicated Cybersecurity Vendors

• Palo Alto Networks: Offers 5G-Native Security , which integrates directly with 5G user plane and control plane architectures. Their Next-Generation Firewalls (NGFW) provide per-device visibility, threat detection, and policy enforcement tailored for private cellular IoT/OT environments, often pairing with ecosystem partners like Salona.

2. Private Cellular & LAN Innovators

• Celona (formerly Salona): Combines private 5G LAN architecture with integrated enterprise security policies. They work alongside firewall vendors (like Palo Alto Networks) to authenticate devices using native mobile identifiers (IMEI/IMSI) rather than just traditional IP addresses, mapping cellular traffic directly into existing enterprise Access Control (NAC) and AAA frameworks.

3. Telecom & Network Infrastructure Giants

If you're looking into a specific deployment, let me know:

• Are you trying to secure an industrial/manufacturing site, office campus, or public sector environment?
• Do you need an integrated firewall vendor or an end-to-end private 5G operator?

Yes. There is a growing ecosystem of vendors offering network-security solutions specifically for private 5G / private cellular networks. The main categories are 5G-network vendors with built-in security, cybersecurity vendors integrating with private-5G platforms, and specialists focused specifically on private-cellular security.

Major providers

Cisco explicitly describes its Private 5G architecture as having end-to-end security, including authentication, authorization, encryption, integrity protection and integration with Cisco ISE.

Ericsson similarly positions security as part of its Private 5G offering, including SIM-based authentication, encryption, network segmentation, role-based access and monitoring.

Particularly interesting cybersecurity specialists

If by "network security solutions" you mean a security product that sits on top of a private 5G network rather than the security capabilities built into the 5G infrastructure itself, I'd focus on these:

• OneLayer — probably the most directly specialized option. Its OneLayer Bridge is specifically designed for private LTE/5G, providing cellular asset visibility, Zero Trust segmentation, threat prevention and asset management.
• Palo Alto Networks — particularly strong if you want enterprise NGFW/Zero Trust security around private 5G. Its Celona integration provides visibility, policy enforcement, threat detection and automated remediation for devices on private wireless networks.
• Fortinet — addresses the 5G RAN-to-core, packet/data network, API and application layers with FortiGate and FortiWeb.
• Nokia — particularly relevant when Nokia is also providing the private 5G infrastructure; its cybersecurity portfolio includes network security, DDoS protection, identity/access management and XDR capabilities.

There are also ecosystem combinations worth considering. For example, Palo Alto Networks has integrations with Nokia, NTT DATA, Celona, OneLayer and others specifically aimed at securing private wireless/5G environments.

Bottom line: if you're evaluating this as a market/vendor landscape, I'd put OneLayer, Palo Alto Networks, Fortinet, Cisco, Ericsson, and Nokia on the initial shortlist. The first three are especially relevant if your question is specifically about cybersecurity layered onto a private 5G network, rather than buying the private 5G network itself.
