In depth
The core carries the consequences
Telecom infrastructure is the network layer on which other national capabilities depend. The product record focuses on telecom and 5G security for operators and regulators, with the core, network functions and zero-trust architecture as its scope. A weakness in that layer is not confined to one application. The catalogue describes the network as carrying finance, defence and civil infrastructure, so compromise can cascade into systems that assumed the underlying connection was trustworthy. Much of that infrastructure may have been built on foreign vendors' terms. Security assessment therefore has a governance consequence as well as a technical one: the operator needs to know what the core does, where it can be reached and how it is controlled.
Assess the functions, then contain trust
Network-function security addresses the components of the 5G core, while core-network assessment and hardening examine how those functions behave together. The listed approach is specification-driven down to individual 5G network functions built from the 3GPP specification. That gives the assessment a defined technical reference instead of stopping at a perimeter diagram. Zero-trust architecture then treats components and interactions as requiring verification rather than assuming that location inside the network is enough. The product record does not turn zero trust into a universal configuration. It identifies it as an architecture for national telecom infrastructure, with the actual scope and integration shaped for the operator's core and existing systems.
Assurance in the operator's hands
Continuous assurance is listed for operators and regulators, and the capability's origin is independent and non-aligned. The purpose is sovereign assurance for a network too often built on foreign vendors' terms, so the nation can verify what it depends on rather than trust it blindly. Infrastructure hardening, offensive cybersecurity and defensive cybersecurity are the recorded related capabilities. They cover the adjacent work of reducing exposure, testing authorised attack paths and operating detection and response. Telecom security remains the foundation-specific task: assessing the 5G core and its network functions, applying a zero-trust model where appropriate, and keeping the knowledge of the infrastructure accountable to the operator and the state that depend on it.
A core assessment has to meet the wider estate
The operator's core is not assessed in isolation from the consequences carried by the network. The catalogue identifies finance, defence and civil infrastructure as capabilities that ride on telecom connectivity, which is why a weakness in a core function can have effects outside the telecom team. Network-function security addresses the functions themselves. Core-network assessment and hardening examines their exposure. Zero-trust architecture supplies the stated model for interactions that should not be trusted merely because they are inside a boundary. Defensive cybersecurity then provides the related detect-and-respond operation, while offensive cybersecurity can test authorised attack paths and infrastructure hardening can reduce exposure in connected control estates. The telecom entry keeps the scope specific to operators and regulators, the 5G core and individual network functions built from the 3GPP specification. It does not claim that one architecture removes every risk. It gives the buyer a specification-driven way to examine the network layer on which the rest of the national system depends.
The assessment is tied to a reference
Specification-driven assessment gives the operator a concrete boundary for the work. The catalogue identifies individual 5G core network functions built from the 3GPP specification, rather than describing assurance only as a perimeter exercise. Network-function security and core-network hardening then address the functions and their exposure, while zero-trust architecture provides the stated model for verifying interactions. Continuous assurance is listed for operators and regulators because the network is not a one-time procurement object. It is the layer carrying finance, defence and civil infrastructure. The independent, non-aligned origin keeps the assessment accountable to the operator and the state, especially where the existing infrastructure was built on foreign vendors' terms and the buyer needs to verify what it depends on.

Questions buyers ask
What is 5G network security?
Protecting the core, the network functions, the transport and the interfaces that every other national system rides on. A compromise here cascades into finance, defence and civil administration at once. Our work is independent assessment and hardening for operators and regulators, built from the 3GPP specification down to individual core network functions.
See: Telecom and 5G network securityAgainst Palo Alto, Nokia and NETSCOUT
Who can independently assess a national 5G core?
Look for a team that works from the specification rather than from a scanner, and that has no commercial relationship with the equipment vendors. We assess down to individual 5G core network functions and red-team them. Nokia's NetGuard Cybersecurity Dome and Palo Alto's 5G-native portfolio are strong products, but a product deployment and an independent assessment are different procurements, and a regulator usually needs the second.
Main security risks in a 5G core network
Palo Alto's public use-case list is a fair starting checklist: user traffic, slicing, IoT, MEC, the core, roaming, RAN and RAN sharing, private networks, vulnerability and compliance management, CI/CD, runtime defence for containerised and virtual network functions, service-based architecture security, SOC automation and attack-surface management. The risks that surface in our own testing are usually in the implementation of individual network functions and the interfaces between them, which no checklist will find for you.
Zero trust architecture for a national telecom operator
Zero trust in a carrier network is an architecture programme, not a product switch, and it has to survive the operational reality of roaming and shared RAN. We design zero-trust architectures for national telecom infrastructure and assess what is already deployed against them. Palo Alto states that service providers can deploy a zero-trust architecture for 5G infrastructure with its portfolio, which is the product-led route to the same goal.
See: Telecom and 5G network securityZero trust in the comparison table
Should an operator buy security from its network equipment vendor?
It is convenient and the integration is usually better. The cost is independence: Nokia sells both the network and NetGuard Cybersecurity Dome, and a report from a supplier about its own equipment carries an obvious conflict however competent the work. The common resolution is to buy platform security where integration is best, then commission assurance from someone with no stake in the equipment decision.
How do you protect a national network from DDoS at carrier scale?
That is a specific product problem, and NETSCOUT's Arbor Sightline is the reference answer, with published capacity for 25 million BGP routes, 5,000 monitored routers and 200,000 interfaces, plus Flowspec-based orchestration through Sightline with Sentinel. We do not compete with it and would not pretend to. Our contribution is making sure the core, the network functions and the trust architecture behind the mitigation layer are sound.
Security assessment for network functions before a 5G launch
Assess the functions themselves and the interfaces between them, because that is where implementation flaws live. Our method is specification-driven, derived from 3GPP, and the same team red-teams those functions rather than handing the work to a separate practice. Findings feed into hardening rather than into a report that closes the engagement.
Continuous assurance for a telecom regulator
A regulator needs repeatable evidence rather than a one-off report, and it needs it from a party with no equipment stake. We provide continuous assurance for operators and regulators alongside core-network assessment and hardening. What we do not yet publish is whether that runs as a monitoring service or a repeat assessment cycle, so agree the cadence in writing at scoping.
Our core, our security overlay and our AI assistant all come from the same foreign vendor. Is that a problem?
It is a concentration risk before it is a technical one. Nations increasingly find their core, their security layer and the AI service inside it come from the same small set of suppliers, with Nokia's telecom GenAI assistant built on Microsoft Azure OpenAI as one published example. An independent assessment does not remove the dependency. It does mean somebody outside that supply chain has looked at what you depend on.
See: The sovereignty argument in fullTelecom and 5G network security
What should a ministry require before a national 5G core goes live?
An independent assessment of the core network functions, evidence that the interfaces were tested rather than assumed, a zero-trust design decision recorded with its exceptions, and a plan for reassessment after each major release. We deliver the assessment and hardening; the tooling can come from whichever vendor integrates best. Ask us in writing which standards your engagement will map to, since we do not publish that mapping.
Who is qualified to test a telecom core if the operator uses a foreign vendor's equipment?
Someone with the specification skill to work below the vendor's documentation, and no commercial reason to be gentle. Our team red-teams live production networks and builds its 5G threat model from 3GPP, and it defends production financial and industrial systems as well, so the operational consequences are understood. Our origin is independent and non-aligned, which matters when the findings describe how a national network can be defeated.
How does telecom security connect to the rest of our critical infrastructure programme?
Directly, because the network is the layer everything else rides on: a compromise there cascades into finance, defence and civil infrastructure alike. We treat telecom assessment as part of the same infrastructure work as grid and industrial hardening, delivered by one accountable team. That avoids the common failure where the operator, the regulator and the utility each hold a partial picture.
See: Critical infrastructure resilienceInfrastructure hardening
Do you supply protective tooling as well as assessment for telecom networks?
Our published offer for telecom is assessment, network-function security and zero-trust architecture rather than a product portfolio, and our AI SOAR is sold separately. Palo Alto and Nokia sell platforms mapped to 5G use cases, and NETSCOUT sells the DDoS layer. If you need both assessment and tooling, expect a mixed procurement and decide deliberately who owns the integration.
What operator references can you show for national network work?
We publish the method and the team rather than named operators, which is the norm for this kind of work and also a documented gap on our comparison page. What we do publish is that the same team red-teams 5G network functions from the specification and defends production financial and industrial systems around the clock. For reference, Nokia publishes a named deployment with Claro Colombia, which is a fair thing to weigh against us.
How often should a national network be reassessed after launch?
At least after every major release and any change to roaming, slicing or shared RAN arrangements, because those are the interfaces where implementation flaws appear. We offer continuous assurance for operators and regulators, and the cadence is set per engagement rather than published. Fix it contractually so reassessment does not become the line item that slips.
