For Agents

Investigate, archive, and act on Amazon GuardDuty findings and manage detectors, member accounts, threat intel sets, and malware scan plans across an AWS organisation.

Use for: I need to enable GuardDuty in a new region with all data sources turned on, List high-severity findings across the organisation in the last 7 days, Archive a finding once an analyst has confirmed it is a false positive, Add an IP CIDR to a trusted IP set so internal scanners stop triggering alerts

Not supported: Does not handle log ingestion, vulnerability scanning, or incident response automation - use for GuardDuty threat detection management and finding triage only.

Jentic publishes the only available OpenAPI specification for Amazon GuardDuty, keeping it validated and agent-ready. Amazon GuardDuty is a continuous threat detection service that analyses VPC flow logs, CloudTrail events, DNS logs, EKS audit logs, and EBS volume data to surface suspicious activity in AWS accounts. The API covers full lifecycle management of detectors, findings, threat intelligence sets, IP allow lists, member accounts, malware protection plans, and publishing destinations across 67 operations.

Install Jentic One Beta

Connect the Amazon GuardDuty to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amazon GuardDuty, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Famazonaws.com%2Famazon-guardduty" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Famazonaws.com%2Famazon-guardduty" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Amazon GuardDuty API.

Create and configure GuardDuty detectors with selected data sources and feature toggles

List and retrieve security findings with filtering by severity, type, and resource

Archive and unarchive findings to triage incidents at scale

Manage trusted IP sets and threat intel sets that suppress or escalate detections

Invite, accept, and manage GuardDuty member accounts under a single administrator

Use Cases

Patterns agents use Amazon GuardDuty API for, with concrete tasks.

★ Centralised Multi-Account Threat Detection

Configure a delegated GuardDuty administrator account that aggregates findings from every member account in an AWS organisation. The API exposes EnableOrganizationAdminAccount, CreateMembers, InviteMembers, and ListMembers so an agent can onboard or audit accounts at scale. Findings flow into the administrator account where they can be filtered, archived, or republished.

Call EnableOrganizationAdminAccount for the security account, then CreateMembers with a list of AccountDetail entries and InviteMembers to send the invitation

Automated Finding Triage

Pull GuardDuty findings on a schedule, classify them by severity and type, archive low-severity false positives, and route the remainder to a SIEM or ticketing system. ListFindings supports rich filter criteria, GetFindings returns full detail for a batch, and ArchiveFindings closes off resolved cases. UpdateFindingsFeedback feeds analyst decisions back to AWS.

Call ListFindings with FindingCriteria filtering severity >= 7 and updatedAt within the last 24 hours, then GetFindings for the returned IDs

Custom Threat Intelligence Feeds

Add organisation-specific threat intelligence by uploading IOC lists to S3 and registering them as ThreatIntelSets. GuardDuty correlates incoming events against the lists and raises a CustomThreatIntel finding when a match occurs. The API also manages IPSets - trusted ranges that suppress noisy detections from known scanners or load balancers.

Call CreateThreatIntelSet with a Location pointing to an S3 object containing IOCs in TXT format, Activate=true, and a Format of TXT

AI Agent Security Operations

Through Jentic, an AI agent can act as an SOC analyst - paginating through findings, archiving false positives by pattern, updating IP allow lists, and triggering malware scans on suspicious EC2 instances. The 67 GuardDuty operations are exposed as Jentic tools so the agent picks the right one from intent.

Search Jentic for 'archive guardduty finding', load the ArchiveFindings schema, and execute it with the DetectorId and a list of FindingIds

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring Amazon GuardDuty by hand means building SigV4 request signing, resolving the GuardDuty host, and handling AWS throttling and retries yourself. Through Jentic you install once, import GuardDuty from the API Directory, store the AWS access keys once, and your agent calls it.

Permission scoping

GuardDuty puts the detector id in the URL path (/detector/{detectorId}/...), so a rule can pin your agent to one detector: it can read filters and IP sets and archive findings for that detector and nothing else. You choose the operations it may call, so deleting a detector or filter is not included unless you add it.

Credential isolation

Your AWS access keys for GuardDuty are stored once, encrypted, by your own Jentic One instance and injected at execution time when the request is signed. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'list GuardDuty findings' or 'archive a finding', and Jentic returns the matching GuardDuty operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Amazon GuardDuty API through Jentic.

Why is there no official OpenAPI spec for Amazon GuardDuty?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amazon GuardDuty via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Amazon GuardDuty API use?

The API uses AWS Signature Version 4 (HMAC) request signing. Through Jentic, AWS credentials are stored encrypted in the vault and requests are signed server-side, so the agent never holds raw access keys.

Can I list and filter GuardDuty findings with the API?

Yes. Call ListFindings on /detector/{detectorId}/findings with a FindingCriteria object that filters by severity, type, resource, or updatedAt. Pass the returned IDs to GetFindings to retrieve full finding details.

What are the rate limits for the Amazon GuardDuty API?

AWS applies per-account, per-region request quotas to GuardDuty operations and these vary by call. List operations have higher throughput than mutation operations like CreateDetector or InviteMembers. Check AWS Service Quotas for current limits.

How do I archive a finding through Jentic?

Search Jentic for 'archive guardduty finding', load the ArchiveFindings schema, and execute with the DetectorId and a list of up to 50 FindingIds. The archived findings remain queryable but no longer count as active.

Can I add custom threat intelligence to GuardDuty?

Yes. Upload an IOC list to S3 in TXT, STIX, OTX_CSV, ALIEN_VAULT, PROOF_POINT, or FIRE_EYE format and call CreateThreatIntelSet with the Location, Format, and Activate=true. GuardDuty raises a Custom finding type when an event matches an entry.

Can I limit what my agent is allowed to do with the Amazon GuardDuty API?

Yes. Because Jentic One is self-hosted, your own rules decide which GuardDuty operations and credentials the agent may use. Since GuardDuty carries the detector id in the URL path (/detector/{detectorId}/...), you can pin the agent to a single detector and allow only the calls you choose, such as reading filters and IP sets and archiving findings for that detector. Destructive operations like deleting a detector or filter stay off limits unless you explicitly add them.
