What is cloud security and why do I need it?

Cloud security protects the compute, containers, and cloud services that power your business, detecting threats, preventing attacks, and enabling fast response across your cloud environment. It's built for the speed, scale, and shared-responsibility model of modern cloud infrastructure.

How does Sophos deliver cloud security across AWS, Azure, GCP, and Oracle OCI?

Sophos ingests native telemetry directly from all four major cloud platforms, including control plane logs, network traffic, identity events, and platform-specific findings, and correlates them in a unified XDR console alongside endpoint, network, and identity signals. This gives security teams complete visibility and the ability to investigate and respond from a single place.

Does Sophos cloud security protect Kubernetes and container environments?

Yes. Sophos secures both Kubernetes nodes and the container workloads running on them, with runtime detection across container environments including Docker, containers, CRI-O, and others. Detections are built around the threat models of cloud-native systems, with visibility that extends into non-root namespaces where most security tools have blind spots.

What is the difference between cloud security with XDR and fully managed cloud security?

Sophos XDR is a self-managed solution that gives your security team unified visibility and investigation tools across cloud, endpoint, network, and identity. Sophos MDR is a fully managed cloud security service where Sophos experts, backed by an Agentic SOC, handle 24/7 monitoring, threat hunting, and response on your behalf.

How does AI improve cloud security threat detection?

AI-driven threat detection identifies malware, exploits, anomalous behaviors, and cloud platform-specific attacks across your workloads and cloud services. Within Sophos MDR, AI agents autonomously triage alerts and conduct investigations, resolving 52% of cases end-to-end in an average of 89 seconds.

How does Sophos protect against identity-based attacks in cloud environments?

Sophos ITDR integrates with Microsoft Entra ID to monitor for credential abuse, privilege escalation, IAM misconfigurations, and impossible travel sign-ins, feeding identity signals directly into the Sophos XDR workflow alongside cloud, endpoint, and network data.

Unified detection and response

Attackers don't stay in one place — they move across cloud, endpoint, network, and identity systems. Sophos XDR connects signals from your entire estate into a single workflow, so you can follow an attack from first entry to full resolution.

Multi-cloud platform coverage

Full protection across AWS, Azure, GCP, and OCI. However you build in the cloud, Sophos delivers comprehensive defense across every host, container, and cloud service.

Identity-focused cloud security

Compromised identities are the fastest path through your cloud environment. Sophos brings cloud identity signals into your workflow, detecting credential abuse and IAM misconfigurations before they become breaches.

Erkennungs- und Reaktionszeiten minimieren

Sophos Workload Protection bietet vollständige Transparenz über Ihre Host- und Container-Workloads und identifiziert Malware, Exploits sowie ungewöhnliche Verhaltensweisen, bevor sie im Netzwerk Fuß fassen.

XDR (Extended Detection and Response) bietet vollständige Transparenz über Hosts, Container, Endpoints, Netzwerke und Cloud-Services.
Cloud-native verhaltensbasierte und Exploit-laufzeitbasierte Erkennungen identifizieren Bedrohungen wie Container Escapes, Kernel-Exploits und Versuche, die Berechtigungsstufe zu erhöhen.
Optimierte Bedrohungsanalyse-Workflows priorisieren die Erkennung hochriskanter Vorfälle und konsolidieren verbundene Ereignisse, um die Effizienz zu steigern.
Die integrierte Live-Response-Funktion richtet ein sicheres Befehlszeilen-Terminal für Hosts zur Beseitigung von Bedrohungen ein.

Integration mit Security, IT und DevOps

Bekämpfen Sie Bedrohungen mit aussagekräftiger Transparenz über Hosts und Container sowie Bedrohungserkennungen während der Laufzeit – mit dem Bereitstellungsmodell, das am besten zu Ihrer Umgebung passt.

Leichtgewichtiger Linux- und Windows-Host-Schutz per Agent

Schützen Sie Ihre Hosts und Container mit einem einzigen Agenten, der über die Management-Konsole von Sophos Central verwaltet wird. Analysieren und reagieren Sie von einem zentralen Ort einfach auf Verhaltens-, Exploit- und Malware-Bedrohungen und verbessern Sie mit automatisierten Erkennungen, intuitiven Abfragen und Funktionen für Remote-Reaktionsmaßnahmen die Durchsetzung von Sicherheitsvorgaben.

Integrierte Threat Intelligence für Linux

Verbessern Sie Security Operations Workflows mit unserer leistungsoptimierten Lösung. Umfasst einen leichtgewichtigen Linux-Sensor für verhaltensbasierte und Exploit-laufzeitbasierte und verhaltensbasierte Erkennungen, der sich per API in Ihre vorhandenen Tools für Automatisierung, Orchestrierung, Protokoll-Management und Incident Response integrieren lässt.

Broad platform coverage.
Uncompromising protection.

Cloud workloads run on many platforms and every one of them is a potential attack surface. Sophos delivers full protection across Linux and Windows operating systems, with a lean, low-overhead agent designed for cloud environments where every resource has a cost. Ingest native telemetry from AWS, Azure, GCP, and OCI, and correlate cloud signals with endpoint, identity, and network data to detect and shut down complex, multi-vector attacks.

Comprehensive Linux distro coverage

Full protection across the Linux distributions most common in cloud environments, including RHEL, Ubuntu LTS, Amazon Linux, Debian, Oracle Linux, and CentOS Stream, on both x86_64 and ARM64 architectures.

Kubernetes and containers

Sophos secures container workloads and Kubernetes environments, protecting both the nodes and the containers running on them, with runtime detection including inside non-root namespaces, where most tools have blind spots.

Windows Server, fully covered

Windows Server is a critical part of many cloud estates. Sophos delivers full protection across all current versions, including anti-ransomware, anti-exploitation, and AI-powered threat detection.

Optimized for cloud performance.

Sophos is engineered to run lean. Minimal CPU and memory footprint means your workloads perform as expected and your cloud spend stays predictable. No performance trade-offs.

Sicherheitsvorfälle schneller beheben

Über unser intuitives Erkennungs-Dashboard können Sie einfach und effizient auf Vorfälle reagieren. Host- und Container-Bedrohungen werden automatisch ermittelt und analysiert. Zu jeder Erkennung wird eine KI-priorisierte Risikobewertung erstellt. Die Bewertungen werden anschließend farbcodiert und dem MITRE ATT@CK Framework zugeordnet, damit Analysten hochriskante Erkennungen schnell priorisieren und beseitigen können.

Zu den Erkennungen zählen unter anderem: Auf Linux abzielende Malware, Speicherbeschädigung, neues Dateiverhalten, ungewöhnliches Anwendungsverhalten, verdächtige interaktive Shell, Container Escapes, Kernel- und Userland-Backdoors, privilegierte Dateivorgänge, Netzwerkermittlung, laterale Bewegungen, Process Injection, Systemermittlung, Änderungen geplanter Aufgaben, Compiler-Nutzung, Verwendung privilegierter Befehle und riskante Entwickleraktivitäten.
