shieldly.ioAbout Shieldly
Shieldly analyses AWS policy documents — IAM policies, CloudFormation templates, S3, Lambda, SQS, KMS and SNS resource policies, plus cost policies — and returns a graded security assessment rather than a raw linter dump. The specific things it looks for are the ones that do not show up as syntax errors: wildcard actions and resources, risky PassRole grants, NotAction traps, public principals, and privilege escalation paths where a policy that looks bounded chains into something that is not. Each analysis returns a score, which is the part that makes it usable as a gate in a workflow rather than a report someone reads once. There is a genuinely low-friction on-ramp: paste an IAM policy JSON into the homepage and get a graded analysis with no signup at all, five free analyses before an account is needed, plus browser-only free tools — an IAM policy linter and a trust-policy explainer — that upload nothing and log nothing. Paid tiers add a cost advisor, analysis history, a compliance panel mapping findings to CIS, SOC 2 and NIST, a watchlist with alerts, a policy diff viewer, and at the team level a direct AWS account connection with automatic scanning, webhooks, Slack alerts and multi-account support.
