Montsecure helps operators, vendors, and critical infrastructure providers understand and harden their mobile networks. From threat modeling and pentesting to hands‑on 5G security testing, we combine standards expertise with practical experience in deployed networks. This becomes increasingly important as NIS2 regulation increases pressure on European operators. We support you across the full lifecycle of your mobile network security: identify and prioritize security risks in complex 4G/5G environments, verify that your controls align with standards and best practices, test real network components and interfaces, not just paper concepts, and prepare for audits, certifications, and customer security reviews.
Modern 5G networks are highly complex. We help you cut through that complexity and focus on the risks that really matter.
You may already have many controls in place. We verify whether they are effective, correctly implemented, and aligned with industry expectations.
We perform hands‑on security testing and penetration testing of 5G Core components to validate that your implementation behaves securely under real‑world conditions.
The RAN is often the most exposed part of the network. We help you understand and strengthen its security posture through comprehensive assessment and penetration testing.
We are a specialized telecom security team with deep experience in 3GPP, GSMA, and BSI contexts. We work vendor‑agnostically and focus on practical, real‑world outcomes.
We use relevant standards and best practices as a foundation, but we go beyond checklist thinking. Our goal is to uncover realistic attack paths and provide actionable mitigation steps.
We work closely with your architects, engineers, and operations teams. Findings are documented clearly, and we make sure they are understood by the people who need to implement changes.
You can share a short description of your architecture and current questions. We will propose a tailored approach, scope, and timeline.
Let's harden your 4G/5G environment together.
