How we started
Two security engineers noticed a pattern. Developers knew the algorithms but struggled to implement them correctly under real constraints. We started teaching what textbooks skip.
What changed
Implementation mistakes cost organizations millions. We shifted focus from perfect theory to practical decisions - when to use which cipher, how to manage keys, where performance matters most.
Where we are now
Our courses combine code walkthroughs with security audits of actual systems. Students work with the same tools they'll use professionally, not simplified examples.
People behind the programs
Larysa Horobets
Cryptography instructor
Spent eight years securing financial systems before teaching. Focuses on symmetric encryption and key rotation strategies in distributed environments.
Denys Vynnyk
Security implementation specialist
Former lead developer at a healthcare tech company. Teaches how compliance requirements shape encryption choices in regulated industries.
Oksana Tkachuk
Program security researcher
Analyzes vulnerability disclosures to find patterns in encryption failures. Designs exercises based on real incidents from the past two years.
Key moments that shaped our approach
2014
Launched first program on symmetric encryption after seeing repeated mistakes in key management across client projects.
2017
Added modules on public key infrastructure after multiple students requested training on certificate validation and TLS implementation.
2021
Introduced performance testing component where students measure overhead of different encryption schemes in simulated production scenarios.
