CloudShield fires parallel scan threads across every AWS region simultaneously. No sequential waiting — every region, every service, all at once.
CloudShield's threat engine polls your AWS environment every 3 seconds via WebSocket. The moment something changes — a new admin user, an open security group, a public bucket — you're alerted instantly.
Every finding gets an AI-generated remediation plan. Review exactly what will change before applying. Every action is logged, reversible, and backed by a full rollback engine.
Enter your AWS Access Key & Secret Key. CloudShield is read-only — credentials are encrypted with AES-128 and never leave your machine.
CloudShield launches parallel threads across all 9 regions, scanning 52+ checks across S3, EC2, IAM, RDS, VPC, KMS, CloudTrail simultaneously.
Every finding is categorized by severity with a plain-English explanation, impacted resource, region, and a detailed remediation plan.

CloudShield covers 8 AWS services: Amazon S3 (14 checks — public access, encryption, versioning, logging), Amazon EC2 & Security Groups (12 checks — open ports, public IPs, EBS encryption), AWS IAM (10 checks — MFA, admin users, stale access keys, wildcard policies), Amazon RDS (6 checks — public access, encryption, backup retention), Amazon VPC (5 checks — flow logs, default VPC, NACLs), AWS CloudTrail (4 checks), AWS KMS (3 checks — key rotation, policies), and Amazon CloudWatch (3 checks). 52+ checks total.
For each finding, CloudShield generates a plan showing the exact AWS API calls needed to fix the issue. You review and approve it — nothing changes without your consent. CloudShield then executes the fix, stores the full before/after state, and lets you roll back any action instantly with one click.
Yes. CloudShield covers CIS, PCI-DSS, and NIST compliance similar to AWS Security Hub, but also adds one-click auto-remediation and a full rollback engine — features Security Hub does not offer. CloudShield is also completely free. AWS Security Hub is a paid service charged per finding per region.
Yes. CloudShield encrypts AWS credentials using AES-128 Fernet encryption before storing them. In desktop mode, keys are stored only on your local machine and never transmitted anywhere. In web mode, keys are stored encrypted in a private database and never shared with third parties.
