Sécurité des infrastructures et des réseaux
Protégez votre infrastructure et vos réseaux avec des mesures de sécurité avancées pour empêcher l’accès non autorisé et réduire les vulnérabilités.
Your network and infrastructure are the foundation of everything your organisation does. A misconfigured firewall, an unpatched system, or a poorly segmented network can expose your entire environment to attackers within minutes. As organisations adopt hybrid cloud architectures and distributed workforces, securing infrastructure has become more complex — and more critical — than ever.
Swiss Expert Group brings together the combined expertise of e-Xpert Solutions, eb-Qual, and One Step Beyond to deliver comprehensive infrastructure and network security services across Switzerland. From next-generation firewalls and Zero Trust architectures to DNS security and backup and recovery, our teams protect the foundations your business depends on.
Our Infrastructure & Network Security Capabilities :
Cloud Security Posture Management (CSPM)
Misconfigurations are among the leading causes of cloud security incidents. We help organisations identify and remediate misconfigurations in hybrid and multi-cloud environments through continuous monitoring and Cloud Security Posture Management (CSPM), ensuring your cloud infrastructure remains secure as it evolves.
Firewalls, IPS & Next-Generation Firewalls (NGFW)
We design, implement, and manage advanced firewall architectures — including Next-Generation Firewalls (NGFW) and Intrusion Prevention Systems (IPS) — to protect your infrastructure perimeter and internal network segments from unauthorised access and known attack patterns.
Zero Trust Architecture (ZTA) & SASE
We help organisations move beyond perimeter-based security by implementing Zero Trust Architecture (ZTA) and Secure Access Service Edge (SASE) frameworks. Combined with MFA and role-based access controls (RBAC), these approaches ensure that access decisions are continuously verified — regardless of user location or device.
SIEM, Network Traffic Analysis (NTA) & Vulnerability Management
Detecting threats requires visibility across your entire network. We deploy and integrate SIEM platforms, Network Traffic Analysis (NTA) tools, and vulnerability management programmes to give your security teams the data and context they need to identify and respond to threats quickly and effectively.
DNS Security
DNS is a critical — and frequently exploited — component of network infrastructure. We implement DNS security controls to block malicious domains, prevent DNS-based data exfiltration, and ensure the integrity of your name resolution infrastructure. eb-Qual holds specific expertise in Infoblox, including dedicated audit services for existing Infoblox deployments.
Backup & Recovery (B&R)
Resilience depends on your ability to recover. We help organisations design and implement backup and recovery architectures that ensure business continuity in the event of a ransomware attack, infrastructure failure, or disaster — aligned with your recovery time and recovery point objectives.
Why Swiss Expert Group for Infrastructure & Network Security?
Infrastructure and network security at Swiss Expert Group draws on the combined expertise of three specialised member companies:
e-Xpert Solutions brings deep cybersecurity consulting and implementation experience across the full range of infrastructure and network security technologies. Its Security Operations Center (SOC), certified ISO 27001 and covered by an ISAE 3000 assurance report issued by a Big4 firm, provides continuous monitoring capabilities for infrastructure threats — including network anomaly detection and incident response.
eb-Qual has specialised in ICT and network infrastructure security since 2002. With a core focus on securing complex network environments, eb-Qual brings particular depth in network architecture, firewall management, and DNS security — including dedicated Infoblox audit services. Its teams operate from Givisiez (Fribourg) and Kloten (Zurich), covering both French-speaking and German-speaking Switzerland.
One Step Beyond, a Microsoft Solutions Partner since 2017, brings cloud-native infrastructure security expertise with a strong focus on Microsoft Azure environments — securing hybrid cloud architectures, enforcing Zero Trust principles, and managing cloud security posture for organisations on their Microsoft cloud journey.
Together, our teams serve organisations across the financial, healthcare, industrial, and public sectors, operating from offices across both French-speaking and German-speaking Switzerland — in Geneva, Gland, Lausanne, Givisiez, Fribourg, and Kloten (Zurich).

Frequently Asked Questions – Infrastructure & Network Security in Switzerland
Q : What is Zero Trust Architecture (ZTA)?
Zero Trust Architecture is a security model based on the principle that no user, device, or system should be trusted by default — whether inside or outside the network perimeter. Every access request is continuously verified against identity, device posture, and context before access is granted. ZTA replaces the traditional implicit trust of perimeter-based security models with explicit, policy-driven access decisions.
Q : What is SASE?
Secure Access Service Edge (SASE) is a cloud-native architecture that converges network security and wide-area networking (WAN) capabilities into a single, cloud-delivered service. It combines technologies such as secure web gateways (SWG), cloud access security brokers (CASB), Zero Trust network access (ZTNA), and firewall-as-a-service (FWaaS) to secure access for distributed users and locations.
Q : What is DNS security and why does it matter?
DNS security refers to measures that protect the Domain Name System from abuse and attack. DNS is frequently exploited by attackers for command-and-control communications, data exfiltration, and phishing campaigns. DNS security solutions filter malicious domain requests, detect anomalous DNS traffic patterns, and protect the integrity of name resolution — making it a critical layer of network defence.
Q : What is Network Traffic Analysis (NTA)?
Network Traffic Analysis (NTA) involves the continuous monitoring and inspection of network traffic to detect anomalies, suspicious behaviours, and threats in real time. NTA tools analyse traffic flows, protocols, and patterns to identify lateral movement, data exfiltration attempts, and other indicators of compromise that may not trigger traditional signature-based detection.
Q : Which infrastructure and network security technologies does Swiss Expert Group work with?
Swiss Expert Group implements and manages solutions from Akamai, Altipeak, Backbox, Check Point, CrowdStrike, Entrust, F5, Forcepoint, Fortanix, Fortra, Infoblox, Kiteworks, Microsoft, Netskope, Palo Alto Networks, Proofpoint, RSA, Silverfort, Semperis, Tufin, and Ubika — selecting the right combination based on your infrastructure architecture and security requirements.
Q : In which Swiss cities does Swiss Expert Group operate?
Swiss Expert Group operates from offices across both French-speaking and German-speaking Switzerland — in Geneva, Gland, Lausanne, Givisiez, Fribourg, and Kloten (Zurich). We serve clients throughout Switzerland and beyond, delivering infrastructure and network security projects and managed services on-site or remotely.
