Scans and Findings

Guard Scans are periodic compliance checks that evaluate your AWS environment against configured rules. Each Scan produces Findings — specific issues that may require attention.


What Scans check

Scans evaluate your environment for:

CategoryExamples
Cost optimisationUnused resources, over-provisioned instances, idle load balancers
Tagging complianceResources missing required tags, inconsistent tag values
Security postureUnencrypted volumes, public S3 buckets, overly permissive security groups
Configuration standardsResources not matching your team's defined standards

Scan frequency and triggers

TriggerWhen it runs
ScheduledRuns automatically on a configurable schedule (daily, weekly, or custom)
ManualTriggered on demand from the Guard Scans page
On changeTriggered when frugally.app detects a change in your AWS environment (new resources, tag changes, etc.)

Configure scan frequency at Guard > Scans > Settings.


Types of findings

Each finding represents a specific issue discovered during a scan.

Finding typeSeverityDescription
Unused resourceMedium–HighA resource is running but has no recent activity (e.g. EC2 instance with 0% CPU for 7+ days)
Over-provisionedMediumA resource is significantly larger than its usage requires
Missing required tagLow–MediumA resource does not have one or more required tag keys
Inconsistent tagsLowTag values do not match the expected controlled vocabulary
Unencrypted storageHighAn EBS volume or S3 bucket does not have encryption enabled
Idle load balancerMediumAn ALB/NLB has no healthy targets registered

Working with findings

Viewing a finding

Click any finding to see:

  • Resource details — The affected resource with its ID, type, region, and tags
  • Explanation — Why this was flagged and what the expected state should be
  • Recommended action — Steps to resolve the finding
  • History — How long this finding has been present across scans

Acting on findings

ActionWhat it does
Create ViolationEscalates the finding to a Violation for formal tracking and remediation
Create ProjectCreates a Guard Project to propose a fix through the approval workflow
DismissMarks the finding as accepted risk with a reason (e.g. "This resource is needed for disaster recovery")
SuppressPrevents this specific finding from appearing in future scans

Exporting results

Click Export on any scan result to download findings as a CSV file. The export includes all finding details, severities, and affected resources.


Scan configuration

Customise what scans check for at Guard > Scans > Rules:

  • Enable/disable rule categories — Turn entire categories on or off
  • Adjust thresholds — Change what counts as "over-provisioned" or "idle"
  • Required tags — Define which tag keys are mandatory for compliance
  • Exclusions — Exclude specific resources, accounts, or regions from scans
tip

Start with the default ruleset and tune thresholds after reviewing your first few scan results. This prevents alert fatigue while still catching the most impactful issues.
