Estonian Defence League’s Cyber Unit Training With CybExer Technologies

Estonian Defence League’s Cyber Unit, a specialized voluntary organization within the Estonian Defence League, is committed to safeguarding Estonian cyberspace. Recognizing the need to enhance their cyber defense capabilities and response strategies against evolving threats, the Cyber Unit partnered with CybExer Technologies to leverage the capabilities of CybExer Cyber Range for their training needs.


As esteemed cybersecurity experts in Estonia, the Cyber Unit Team understood the importance of continuously updating their skills to stay ahead in the ever-changing cyber landscape. While already renowned for their proficiency, they acknowledged the necessity of ongoing training and practical experience to maintain their leadership in the field.

They sought a training solution that would provide their professionals with advanced education and hands-on exercises, ensuring they remained at the forefront of cybersecurity knowledge and effectively protected Estonia’s critical information infrastructure. Additionally, there was a challenge in providing existing members with real-life hands-on defensive activities within offensive cyber operations and testing and validating new members to identify their strengths and areas for improvement.


To address these challenges, the Cyber Unit Team utilized the capabilities of CybExer Cyber Range, an advanced training platform designed to enhance cyber capabilities and strengthen resilience. This collaboration allowed the Cyber Unit Team’s cyber security and IT professionals to engage in highly realistic live-fire exercises, immersing themselves in simulations of actual cyber attacks within a controlled environment.

The exercises replicated sophisticated hacking techniques and advanced cyber threats commonly encountered in high-level cybersecurity operations. By leveraging the capabilities of the cyber range, the Cyber Unit Team’s professionals honed their skills in identifying, analyzing, and mitigating vulnerabilities, fortifying their cyber defense posture and empowering them to confidently tackle even the most sophisticated cyber threats. Additionally, these exercises served as a means to test and evaluate team members’ suitability within the Cyber Unit, ensuring a cohesive and effective team to support and protect Estonian cyberspace.
