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.

AI-native cloud security, from runtime to response.

Complete protection across every cloud workload, container, and platform.

Unify cloud telemetry from hosts, containers, and cloud services into the same XDR detection and investigation workflow as your endpoint, network, and identity signals. One console. One investigation workflow. No blind spots.

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.

Protect, detect and respond at cloud speed

Cloud threats are fast, targeted, and increasingly sophisticated. AI is giving attackers new ways to strike at scale. Sophos XDR delivers complete visibility across your cloud workloads and platforms, using AI-powered detection to identify malware, exploits, anomalous behaviors, and cloud-specific attacks before they gain a foothold.

Connect your cloud. Unify your defense.

Sophos connects natively with your cloud platforms, ingesting telemetry directly from cloud APIs, syslog sources, and third-party tools, and correlating it all in a unified context lake. One place to investigate and act, no manual log stitching, and no tool sprawl.

Deep integrations across every major cloud platform

AWS: Full control plane visibility and traffic context from CloudTrail, GuardDuty, VPC Flow Logs, ALB logs, WAF logs, and CloudWatch logs.
Azure: Complete authentication, traffic, and perimeter coverage via Activity Logs, Network Watcher Flow Logs, Event Hubs, Application Gateway, Azure Firewall, and Azure Front Door, with native Entra ID integration for deep identity risk analysis.
GCP: Control plane, networking, and native threat intelligence through Cloud Audit Logs, VPC Flow Logs, GKE Dataplane, and Security Command Center findings.
Oracle OCI: End-to-end visibility across authentication, traffic, data access, and perimeter security via Audit Logs, VCN Logs, Network Firewall Traffic Logs, Object Storage logs, WAF logs, and Load Balancer logs.

No source left behind

Sophos isn't limited to what cloud platforms provide. API feeds, syslog sources, and hundreds of third-party solutions are supported. However your cloud environment is built, Sophos can ingest, enrich, and act on your data.

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.

Cloud threat detection that sees what others miss

Sophos XDR gives security teams a single place to detect, investigate, and respond to threats across cloud platforms, workloads, and your broader estate. Detections are tuned for cloud environments out of the box and fully customizable for specific cloud events and services.

AI-prioritized risk scores, automatic MITRE ATT&CK mapping, and easy-to-understand AI-generated summaries mean analysts spend less time triaging and more time responding.

Cloud detections include:

AWS snapshot exfiltration and cloud control plane recon
Suspicious configuration changes and IAM misconfigurations
Credential abuse, impossible travel sign-ins, and privilege escalation
Container escapes, kernel backdoors, and malware targeting Linux
Lateral movement, process injection, and network discovery
Memory corruption, suspicious interactive shells, and privileged command usage
And more…

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?
