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.

更多了解 XDR

See what’s hiding in your cloud

Ask questions in plain language and get answers fast. Sophos XDR gives SecOps and DevOps teams AI-powered assistants for threat hunting and investigation, querying telemetry across all your cloud accounts, workloads, and services from a single console.

Example investigations:

Are there unusual outbound connections or potential exfiltration attempts across your cloud environments?
Which cloud storage accounts or S3 buckets are misconfigured or exposed to the public internet?
Has any snapshot exfiltration activity been detected across your AWS environment?
Are there suspicious configuration changes or privilege escalations in your cloud control planes?
Which cloud security groups have overly permissive rules that expose resources to the internet?
Are there signs of credential abuse or unusual authentication patterns across your cloud identity estate?
