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 infrastructure and network are the foundation of everything your organisation does. A misconfigured firewall, an unpatched system, or an unsegmented network can expose your entire environment within minutes. As hybrid cloud architectures and distributed workforces become the norm, securing infrastructure has grown more complex — and more critical — than ever.
At e-Xpert Solutions, our infrastructure and network security engineers have been protecting Swiss organisations since 2001. We bring hands-on expertise across the full stack — from next-generation firewalls and Zero Trust architectures to DNS security, network policy management, and cryptographic infrastructure. Our engineers do not just configure tools: they design resilient, auditable security architectures that hold up under real-world attack conditions and regulatory scrutiny.
Our Infrastructure & Network Security Capabilities :
Next-Generation Firewalls (NGFW) & Intrusion Prevention
The firewall remains the most fundamental control in network security — but only when it is properly architected, maintained, and monitored. Our engineers design, deploy, and manage NGFW environments using Check Point and Palo Alto Networks — applying segmentation strategies, micro-perimeters, and intrusion prevention rules tuned to your environment. We also automate firewall rule lifecycle management using Tufin, ensuring that firewall policies remain clean, compliant, and auditable as your infrastructure evolves. Tufin is a platform in which e-Xpert Solutions holds deep certified expertise, including network topology management and automated change workflows.
Zero Trust Architecture (ZTA) & SASE
The traditional perimeter is gone. Our engineers help organisations transition to Zero Trust Architecture — a model in which no user, device, or system is trusted by default, and every access request is continuously verified against identity, device posture, and context. We implement ZTA using a combination of identity controls (RSA, Silverfort), network segmentation, and Secure Access Service Edge (SASE) frameworks that converge network and security services for distributed users and locations. Every access decision is explicit, policy-driven, and logged.
Firewall Policy Management & Network Automation
As network environments grow in complexity, firewall policy management becomes a significant operational and compliance burden. e-Xpert Solutions is a certified Tufin partner — one of the few in Switzerland with deep expertise in Tufin Orchestration Suite. We deploy Tufin to provide full network topology visibility, automated policy analysis, change management workflows, and compliance reporting across multi-vendor firewall environments. This enables your network team to manage change at scale while continuously demonstrating compliance to ISO 27001, FINMA, and PCI-DSS auditors.
Web Application & Network Traffic Protection
Protecting network traffic at scale requires specialised platforms for load balancing, application delivery, and DDoS mitigation. Our engineers deploy and operate F5 BIG-IP and F5 Distributed Cloud for advanced application traffic management, SSL/TLS offloading, and network-layer DDoS protection. For cloud-scale and edge protection, we work with Akamai — delivering content delivery network (CDN) security, DDoS mitigation at the edge, and Akamai Guardicore Segmentation for zero trust network access. Ubika WAAP extends this protection to web applications and APIs.
Cryptographic Infrastructure — PKI, HSM & Key Management
Cryptographic infrastructure underpins the security of everything from VPN connections and digital certificates to code signing and data encryption. Our engineers design and implement Public Key Infrastructure (PKI) and Hardware Security Module (HSM) environments using Entrust, Fortanix, and Keyfactor — ensuring that cryptographic keys and certificates are generated, stored, and managed with the rigour required by regulated environments. We also operate SSLCert — our proprietary Certificate Lifecycle Management platform — for automated SSL/TLS certificate discovery, renewal, and compliance reporting across enterprise environments.
Network Security Policy & Access Control
Network security is not just about perimeter controls — it is about governing how users and systems access network resources, and ensuring that access policies are enforced consistently across the environment. We implement network access controls, web filtering, and security policy enforcement using Forcepoint and Proofpoint — covering outbound traffic control, web gateway security, and network-based DLP. For identity-based network access and digital trust, we deploy Altipeak’s digital identity platform to bind user identity to network access decisions.
Backup, Recovery & Infrastructure Resilience
Security is not complete without resilience. Our engineers design backup and recovery architectures that ensure business continuity in the event of a ransomware attack, infrastructure failure, or disaster — using Fortra’s data protection solutions. Recovery time and recovery point objectives are validated through regular testing, and recovery procedures are documented to satisfy FINMA, ISO 27001, and NIS2 business continuity requirements.
Cloud Security Posture Management (CSPM)
Cloud misconfigurations are the leading cause of cloud security incidents — and they are often invisible without dedicated tooling. We help organisations identify and remediate misconfigurations in hybrid and multi-cloud environments through continuous Cloud Security Posture Management, integrating cloud security monitoring into our At-Defense SOC for real-time alerting and response. Our CSPM implementations cover AWS, Microsoft Azure, and multi-cloud environments.
Why e-Xpert Solutions for Infrastructure & Network Security?
Infrastructure and network security at e-Xpert Solutions is an engineering discipline built on more than two decades of field experience in Switzerland. Our certified specialists hold advanced qualifications across Check Point, Palo Alto Networks, F5, Akamai, Tufin, Entrust, Fortanix, and Forcepoint — and they bring both the technical depth to architect complex environments and the regulatory knowledge to ensure those architectures satisfy FINMA, ISO 27001, PCI-DSS, and NIS2 requirements.
Our engineers contribute actively to the cybersecurity community through MITRE ATT&CK and SIGMA publications, and have published CVEs for Microsoft, F5, and Abacus — a track record that reflects genuine offensive security expertise applied to defensive infrastructure design.
Infrastructure security at e-Xpert Solutions is also directly connected to our At-Defense SOC — certified ISO 27001 and covered by an ISAE 3000 assurance report issued by a Big4 firm. Network events, firewall alerts, and infrastructure anomalies feed directly into our 24/7 SOC for continuous monitoring and rapid incident response — providing a seamless path from infrastructure deployment to full managed security operations.
We operate from our offices in Geneva (Plan-les-Ouates) and Lausanne, serving organisations across the financial, healthcare, industrial, luxury, and public sectors in Switzerland and internationally.

Frequently Asked Questions – Infrastructure & Network Security in Switzerland
Q : What is Zero Trust Architecture (ZTA) and how is it implemented?
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. Implementation typically involves four layers: identity verification (ensuring users are who they claim to be, using MFA and risk-based authentication), device posture assessment (verifying that devices meet security standards before granting access), network micro-segmentation (limiting lateral movement by restricting traffic between network segments), and continuous monitoring (logging and analysing all access requests and network flows). e-Xpert Solutions implements ZTA using RSA, Silverfort, Check Point, Palo Alto Networks, and Akamai Guardicore — tailored to your existing infrastructure.
Q : What is Tufin and why is it used for firewall management?
Tufin Orchestration Suite is a network security policy management platform that provides unified visibility and control across multi-vendor firewall environments — including Check Point, Palo Alto Networks, Fortinet, Cisco, and cloud security groups. It automates firewall rule analysis, change management, access risk assessment, and compliance reporting. For organisations with complex firewall estates, Tufin eliminates the operational burden of manual policy management and provides the audit-ready compliance reports required by ISO 27001, FINMA, and PCI-DSS. e-Xpert Solutions is one of the few certified Tufin partners in Switzerland.
Q : What is the difference between a WAF and a NGFW?
A Next-Generation Firewall (NGFW) operates at the network layer — controlling traffic flows between network segments, enforcing application-aware policies, and blocking known threats at the perimeter. A Web Application Firewall (WAF) operates at the application layer — inspecting HTTP/HTTPS traffic specifically to protect web applications and APIs from attacks such as SQL injection, XSS, and API abuse. NGFWs and WAFs are complementary controls: the NGFW secures the network perimeter, while the WAF secures individual applications. At e-Xpert Solutions, we deploy both — Check Point and Palo Alto for NGFW, F5 and Ubika for WAF.
Q : What is a Hardware Security Module (HSM) and when is it required?
A Hardware Security Module (HSM) is a dedicated physical or virtual device that generates, stores, and manages cryptographic keys in a tamper-resistant environment. HSMs are required when cryptographic operations must be performed with the highest level of assurance — including PKI root certificate authorities, code signing, payment processing, and encryption key management for regulated data. FINMA guidelines for financial institutions and PCI-DSS requirements for payment environments both mandate HSM-based key protection for specific use cases. e-Xpert Solutions designs and implements HSM environments using Entrust and Fortanix.
Q : How does infrastructure security integrate with your At-Defense SOC?
Infrastructure and network security events feed directly into e-Xpert Solutions’ At-Defense SOC — certified ISO 27001 and covered by an ISAE 3000 report. Firewall logs, network flow data, configuration change alerts from Backbox, and CSPM findings are all ingested into our next-generation SIEM for real-time correlation. Our SOC analysts monitor these data sources 24/7, perform threat hunting across network telemetry, and respond to incidents with a defined SLA of under one hour for critical events.
