Background

PT Telkomsat, a leading satellite service provider, recognizes that technology alone is not enough to secure an organization—the human element is the ultimate line of defense. Throughout 2025, Telkomsat partnered with SiberMate to transition from a high-risk profile to a security-conscious culture through data-driven training and simulations.

The Challenge

High Human Risk Vulnerability

At the beginning of the reporting period, Telkomsat faced significant challenges regarding employee security awareness:

  • The organization started with a maximum Overall Risk Score of 900, indicating a high level of vulnerability.

  • The initial Phishing Risk Score stood at 350, highlighting a critical need for better resistance against social engineering attacks.

  • There was a lack of measurable data regarding how employees would react to real-world cyber threats

The Solution

A Comprehensive Security Culture Program

SiberMate deployed a multi-layered strategy to identify, educate, and test the workforce throughout the year:

  • Continuous Education: Employees were enrolled in a robust training program, resulting in 2,401 total course completions.
  • Active Threat Simulation: SiberMate sent out 970 simulated phishing emails to provide hands-on experience in identifying malicious content.
  • Real-time Risk Monitoring: The platform provided monthly tracking of the Overall Compromise Rate, allowing for immediate adjustments to training focus.

The Impact

Measurable Security Excellence

The collaboration between PT Telkomsat and SiberMate delivered exceptional results by December 2025:

1. Significant Risk Reduction

  • The Overall Risk Score was successfully reduced by 37%, dropping from 900 down to 565.

  • This improvement demonstrates a measurable mitigation of human risk across the entire organization.

2. Mastery in Phishing Defense

  • The Phishing Risk Score saw a dramatic improvement, falling from 350 to just 24.

  • The Overall Compromise Rate (the percentage of users who fell for simulations) was maintained at a low 4.1%, proving that employees are now highly vigilant.

3. Top-Tier Knowledge and Engagement

  • Telkomsat achieved an Average Score of 90.4% across all security courses, confirming a deep understanding of security principles.

  • The program maintained a 100% Completion Rate, showcasing the dedication of Telkomsat’s employees toward protecting company assets.

Conclusion

The Value of SiberMate

By partnering with SiberMate, PT Telkomsat has successfully turned a major vulnerability into a strategic advantage. The ability to transform raw behavioral data into a clear reduction in risk has provided Telkomsat with the confidence that their workforce is prepared to defend against the evolving cyber threat landscape.
