Rambunct Elevates Cybersecurity Training for Masterfully with AWS Sandbox & IAM Boundaries

Background

Masterfully partnered with Rambunct to build secure, scalable AWS sandbox environments with boundary IAM, delivering hands-on cybersecurity training that combines real-world cloud scenarios with strict access control, automated cost management, and high learner engagement.

The Challenge

Masterfully needed a secure, flexible platform to provide hands-on AWS-based cybersecurity training without compromising security, cost efficiency, or learner experience.
  • Difficulty creating isolated AWS training environments with realistic but secure cloud scenarios.
  • Complex IAM permission management needed for skill-based access control and monitoring.
  • Risk of cost overruns due to ungoverned resource usage in training sessions.
  • Limited ability to simulate enterprise-grade security incidents in a controlled environment.

Our Solution

Rambunct delivered a secure, automated sandbox framework using IAM boundaries and AWS security tools to power real-world training simulations.
  • Provisioned isolated AWS accounts per session with IAM boundaries and Service Control Policies (SCPs).
  • Implemented role-based, scenario-specific IAM policies to support progressive training tracks.
  • Automated training environment lifecycle with resource tagging, cleanup, and cost alerts.
  • Deployed GuardDuty, Security Hub, and CloudTrail to simulate and assess cloud security incidents.

The Result

The solution enabled Masterfully to deliver world-class cybersecurity education with measurable gains in effectiveness, security, and scalability.
  • 95% increase in hands-on training effectiveness using realistic cloud threat simulations.
  • Zero security incidents due to tightly controlled IAM boundaries and SCPs.
  • 80% faster environment setup through automation and standardized policy deployment.
  • 90% cost predictability via automated resource lifecycle and budget monitoring.
