What is Amazon GuardDuty
AWS offers GuardDuty as a managed service for threat detection, enabling continuous monitoring to protect your AWS accounts and data stored in S3. It does this by analyzing data (account and network activity) found in VPC Flow Logs, DNS Logs, and AWS CloudTrail Events. It also has a threat detection mechanism to detect anomalies and malicious IP addresses, plus it utilizes machine learning for more accurate threat detection.
One of the key benefits of using GuardDuty is that it continuously monitors your AWS accounts for threats and anomalies. Another advantage is that it works completely independently from your resources; you don't need to enable any service or install any software, and there's no performance overhead on your workload. On top of that, alerts provided by GuardDuty are detailed and actionable and can be easily integrated with your existing event management and workflow systems.

3. Stop unauthorized activity - Guard against the use of compromised credentials, unusual data access in Amazon Simple Storage Service (S3), API calls from known malicious IP addresses, and more.
Pricing
AWS provides a complimentary full access 30 day trial of the service upon the first activation so you can see if it's a good fit for you. To estimate the costs after that, Amazon GuardDuty generates an estimated price for how much you would have spent without the free trial.
The Pricing is based on the amount of analysis of your AWS log data. VPC Flow Logs and DNS Logs will be charged per GB/month, and the CloudTrail Event Logs will be charged per 1,000,000 events/month. Even though Pricing can differ from region to region, in general, it consists of the following:
