Customer stories

See how these organizations achieved more with Synology.

"Before using C2 Password, I often had to reset my students' passwords. Besides being time consuming, it prevented us from focusing on our work. C2 Password fixed all this, helping our students understand the importance of privacy and credential safekeeping along the way."

Samir Buric, Professor and Lecturer, Electrical and Wood Processing High School of Bihac, Bosnia and Herzegovina

"C2 Transfer’s end-to-end encryption helps our organization upload confidential files to external servers more securely. In addition, one-time password protection through email or phone further reduces our worries about data leaks."
