Opérations de sécurité et protection contre les menaces
Surveillez, détectez et répondez aux menaces pour protéger vos systèmes et opérations contre les risques évolutifs.
Cyber threats targeting Microsoft cloud environments are increasing in sophistication and frequency — credential attacks, business email compromise, ransomware delivered through cloud applications, and lateral movement across Microsoft 365 and Azure workloads. Detecting and responding to these threats requires security operations capabilities that are natively integrated with the Microsoft ecosystem: a cloud-native SIEM that ingests Microsoft signals, XDR that correlates threats across identity, endpoint, email, and cloud applications, and AI-powered investigation tools that accelerate response.
One Step Beyond specialises in security operations within the Microsoft cloud ecosystem. As a certified Microsoft Solutions Partner for Modern Work & Security, our engineers implement Microsoft Sentinel as SIEM and SOAR, Microsoft Defender XDR for unified cross-domain threat detection, and Microsoft Security Copilot for AI-accelerated investigation and response — delivering security operations capabilities that are fully integrated with your Microsoft 365 and Azure environment. For broader security operations beyond Microsoft — At-Defense managed SOC, Splunk, Elastic, Cribl, CrowdStrike, Check Point, Palo Alto — these platforms are delivered by our Swiss Expert Group partners e-Xpert Solutions and eb-Qual, who hold deep certified expertise including the ISO 27001 and ISAE 3000 certified At-Defense SOC.
Our Security Operations Capabilities :
Microsoft Sentinel — Cloud-Native SIEM & SOAR
Microsoft Sentinel is Microsoft’s cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform — ingesting signals from across the Microsoft ecosystem and third-party sources for real-time threat detection, investigation, and automated response.
Our engineers design and implement Microsoft Sentinel environments tailored to your organisation’s threat landscape and compliance requirements — configuring data connectors for Microsoft 365, Azure, Entra ID, Defender products, and third-party sources, building custom detection rules and analytics using KQL, implementing automated playbooks (Logic Apps) for common incident response workflows, and creating dashboards and workbooks for security posture visibility. Every Sentinel implementation is built with Swiss regulatory requirements in mind — log retention periods aligned with FINMA and nLPD obligations, audit trail integrity, and compliance workbooks for ISO 27001 evidence collection.
Microsoft Defender XDR — Unified Threat Detection
Microsoft 365 Defender XDR (Extended Detection and Response) unifies signals from Defender for Endpoint, Defender for Identity, Defender for Office 365, and Defender for Cloud Apps into a single threat investigation and response experience — automatically correlating alerts into incidents, identifying attack chains across multiple products, and providing a unified view of the entire attack scope.
Our engineers configure Microsoft Defender XDR to maximise detection coverage across your Microsoft environment — tuning detection policies for each Defender product, configuring automatic investigation and response (AIR) to reduce analyst workload, enabling advanced hunting for proactive threat search, and integrating XDR incidents into Microsoft Sentinel for centralised security operations. For organisations that want 24/7 managed detection and response on top of Microsoft Defender XDR, we connect XDR telemetry to our Swiss Expert Group partner’s At-Defense SOC — certified ISO 27001 and covered by an ISAE 3000 report.
Microsoft Security Copilot — AI-Accelerated Investigation
Microsoft Security Copilot brings generative AI to security operations — enabling analysts to investigate threats faster, summarise incidents in natural language, query security data in plain English, and generate incident reports automatically. It integrates with Microsoft Sentinel, Defender XDR, Entra ID, and Intune — providing AI-powered assistance at every stage of the investigation and response workflow.
Our engineers implement Microsoft Security Copilot for security teams looking to accelerate their investigation and response capabilities — configuring Copilot for Security standalone capabilities, integrating Copilot plugins for specific Microsoft security products, and training security teams on effective prompt engineering for security investigation use cases. For organisations adopting AI in security operations, we also ensure that Security Copilot is deployed with appropriate access controls and audit logging aligned with nLPD and FINMA requirements.
Microsoft Defender for Identity — User Behaviour & Lateral Movement Detection
Microsoft Defender for Identity (formerly Azure ATP) monitors Active Directory and Entra ID activity to detect identity-based attacks — credential theft, pass-the-hash, Kerberoasting, lateral movement, and domain compromise techniques. It provides a timeline view of every user’s activities, identifies suspicious behaviour patterns using machine learning, and correlates identity threats with signals from other Defender products through Microsoft Defender XDR.
Our engineers deploy Defender for Identity sensors across your Active Directory domain controllers and configure alert policies tuned to your environment — integrating identity threat signals into Microsoft Sentinel for centralised correlation and investigation. Defender for Identity is a critical control for detecting the lateral movement and credential abuse that precede most ransomware attacks in Microsoft environments.
Microsoft Defender for Office 365 — Email & Collaboration Threat Protection
Email and collaboration platforms are the primary delivery vector for phishing, business email compromise (BEC), malware, and ransomware. Microsoft Defender for Office 365 provides advanced threat protection for Exchange Online, Teams, SharePoint, and OneDrive — covering anti-phishing, safe links, safe attachments, and anti-malware with Microsoft’s real-time threat intelligence.
Our engineers configure Defender for Office 365 Plan 2 for organisations requiring advanced capabilities — attack simulation training to test and improve user resilience, threat explorer for proactive investigation of email threats, automated investigation and response for email incidents, and campaign views to identify coordinated attack patterns across your organisation. Email threat signals integrate with Microsoft Defender XDR and Microsoft Sentinel for unified security operations.
Microsoft Sentinel Integration with At-Defense SOC
Microsoft Sentinel provides the SIEM technology — but effective security operations requires human expertise operating it 24 hours a day, 7 days a week. For organisations requiring managed detection and response on top of their Microsoft Sentinel deployment, One Step Beyond collaborates with our Swiss Expert Group partner e-Xpert Solutions to connect Microsoft Sentinel to the At-Defense SOC — a 100% Swiss managed SOC certified ISO 27001 and covered by an ISAE 3000 assurance report issued by a Big4 firm.
This combination delivers the best of both worlds: Microsoft Sentinel’s cloud-native SIEM capabilities, fully integrated with your Microsoft 365 and Azure environment, operated by the At-Defense SOC team — analysts certified GCFA, GCIH, GCFR, GEIR, OSCP, and OSCE — providing 24/7 threat monitoring, incident response, threat hunting, and darknet monitoring. Zero breaches recorded among At-Defense SOC clients since 2018.

Frequently Asked Questions – Security Operations in Switzerland
Q : What is Microsoft Sentinel and how does it differ from traditional SIEM?
Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform built on Azure. Unlike traditional on-premises SIEM solutions — which require significant hardware investment, manual tuning, and complex maintenance — Microsoft Sentinel scales automatically with your data volume, ingests signals from across the Microsoft ecosystem without additional connectors, uses Microsoft’s global threat intelligence for detection, and integrates natively with Microsoft Defender products for automated investigation and response. For Microsoft 365 and Azure environments, Sentinel is the natural SIEM choice — providing the deepest integration and the broadest coverage of Microsoft-specific attack techniques.
Q : What is XDR and how does Microsoft Defender XDR work?
Extended Detection and Response (XDR) is a security approach that correlates threat signals across multiple security domains — endpoint, identity, email, cloud applications, and network — into a unified investigation experience. Microsoft Defender XDR automatically correlates alerts from Defender for Endpoint, Defender for Identity, Defender for Office 365, and Defender for Cloud Apps into incidents — showing the full attack chain across all affected assets, automated investigation results, and recommended response actions. This unified view enables security analysts to understand and respond to attacks that span multiple Microsoft products in a fraction of the time required with individual product consoles.
Q : What is Microsoft Security Copilot?
Microsoft Security Copilot is a generative AI assistant for security operations — embedded in Microsoft Sentinel, Defender XDR, Entra ID, and Intune. It enables security analysts to investigate threats in natural language, summarise incidents for executive reporting, query Sentinel logs with plain-English questions, generate step-by-step remediation guidance, and produce incident reports automatically. Security Copilot does not replace human analysts — it accelerates them, reducing the time to triage and investigate incidents and making advanced capabilities accessible to analysts at all experience levels.
Q : What is the At-Defense SOC and how does it relate to One Step Beyond?
At-Defense is a 100% Swiss managed Security Operations Center operated by e-Xpert Solutions — One Step Beyond’s partner within Swiss Expert Group. It is certified ISO 27001 since 2021 and covered by an ISAE 3000 assurance report issued by a Big4 firm, with analysts holding GCFA, GCIH, GCFR, GEIR, OSCP, and OSCE certifications. It operates 24/7 with incident response included, zero breaches recorded since 2018, and less than 3% of alerts escalated to client teams. One Step Beyond deploys Microsoft Sentinel and Defender XDR — and connects these to At-Defense for 24/7 managed monitoring and response, delivering a fully integrated Microsoft cloud security operations capability.
Q : How does Microsoft Sentinel support FINMA compliance?
Microsoft Sentinel directly supports FINMA circular 2023/1 on operational risks and resilience — which requires Swiss financial institutions to implement continuous security monitoring, incident detection, and response capabilities.
