Personal Gmail accounts with GCP IAM access bypass your security controls and offboarding. Learn how to detect, remove, and block them with org policy and CI gates.
Learn why an AWS Lambda function with a deleted IAM execution role fails silently, how to detect it, fix it with the CLI, and prevent it with IaC and CI/CD.
Learn why an Azure NSG rule exposing MySQL port 3306 to the public internet is dangerous, how to remediate it, and how to prevent it with policy as code.
Azure NSG rules exposing Kibana on port 5601 leak your logs and Elasticsearch data to the internet. Learn why it matters and how to lock it down fast.
Learn why a GCP managed instance group without autoscaling risks outages and wasted spend, plus CLI, Terraform, and policy-as-code fixes.
Learn why S3 buckets without a server-side encryption configuration fail audits, and how to enable SSE-KMS, re-encrypt objects, and enforce it in CI/CD.
Learn what unused AWS Elastic Network Interfaces are, why orphaned ENIs waste IPs and hide costs, and how to find, delete, and prevent them with CLI and IaC.
Learn why single-AZ Auto Scaling groups are a reliability risk, how to spread them across multiple availability zones, and how to prevent the issue in CI/CD.
Learn why missing CloudWatch alarms for route table changes are a risk, and how to fix CIS 3.13 with CLI, Terraform, and policy-as-code on AWS.
Learn why Azure Recovery Services Vaults need diagnostic logging, the risks of running blind, and how to fix and enforce it with CLI, Terraform, and Azure Policy.
No Azure Bastion host often means VMs are exposed over public RDP/SSH. Learn the risk and how to deploy Bastion, remove public IPs, and prevent recurrence.
Learn why Azure Recovery Services Vaults should use customer-managed keys (BYOK), the risks of default encryption, and how to fix and enforce CMK.

Learn why a public AWS Transfer Family endpoint is risky, how to switch to a secure VPC endpoint, and how to prevent public SFTP servers with policy-as-code.
Learn why disabled automated backups on GCP Cloud SQL is a critical risk, how to enable them via gcloud, console, and Terraform, and how to enforce it in CI/CD.
Learn why AWS needs a CloudWatch alarm for network ACL changes (CIS 3.11), the risks of skipping it, and step-by-step CLI and Terraform fixes.
Learn why GCP load balancer SSL policies allowing weak ciphers or old TLS versions are a risk, and how to enforce TLS 1.2 with gcloud, Terraform, and policy-as-code.
Learn why an Azure Application Gateway with no SSL policy is a security risk, how to enforce TLS 1.2+, and how to prevent it with IaC and Azure Policy.
