Amazon GuardDuty vs Wiz Defend

Amazon GuardDuty monitors AWS accounts and workloads for malicious activity and generates security findings for response. It analyzes CloudTrail, VPC Flow, DNS, S3, Aurora login, AWS Backup, AI workload, and runtime activity. Detection combines AI, machine learning, anomaly detection, and AWS and third-party threat intelligence. Runtime Monitoring covers EKS, ECS workloads including those on Fargate, and EC2 instances. GuardDuty can scan EC2-attached EBS volumes after suspicious activity and detect potentially harmful uploads to S3 buckets. AI Protection addresses threats such as unusual model invocations, cost harvesting, and prompt injection attempts in Amazon Bedrock and SageMaker workloads. Findings can go to AWS Security Hub, EventBridge, Amazon Detective, or third-party solutions. Foundational protections require no additional security software or infrastructure to deploy and maintain. The service is pay as you go: charges depend on analyzed data and vary by source and AWS Region. New accounts can receive a 30-day trial in supported Regions, and some features are unavailable in some Regions.

Wiz Defend provides real-time threat detection, investigation, and response across cloud environments, including AI applications. It combines runtime signals from the Wiz sensor, cloud and SaaS logs, and agentless risk context to trace attack paths and assess possible blast radius. Telemetry maps to MITRE ATT&CK, and the product identifies coverage gaps before an incident. Its Blue Agent triages threats and prepares an investigation and verdict for analyst review. Response options include cloud containment playbooks, root-cause analysis, source-code remediation, and automation through Wiz Workflows. Wiz Defend detects AI runtime threats including prompt injection, model exfiltration, and MCP server attacks. The Wiz Sensor add-on monitors and protects VM, containerized, and serverless container workloads. Kubernetes capabilities include file integrity monitoring, drift detection, threat monitoring, and blocking on container hosts. Integration with Google Security Operations lets analysts investigate in either platform, with threat status, severity, and comments syncing in real time. Wiz describes the product for SOC, threat intelligence, and incident response teams. Licensing is modular, with pricing by request; there is no free plan.
