Introduction to Sync.com: Zero-Knowledge Encrypted Cloud Storage for Privacy in 2025

In an era where data privacy is paramount, Sync.com stands out as a leading zero-knowledge encrypted cloud storage service dedicated to user privacy and security. Unlike traditional providers, Sync.com employs end-to-end encryption, ensuring only you and authorized users can access files—the service provider cannot view them. This zero-knowledge encryption protects sensitive information from unauthorized access, making Sync.com ideal for personal documents, business projects, team collaborations, and secure file sharing in 2025.

Why choose Sync.com for secure cloud storage in 2025?

The healthcare sector exemplifies the risks of unsecured cloud storage, with breaches surging and healthcare facing the highest impact.

From 2005 to 2019, these breaches affected 249.09 million individuals globally, with 157.40 million impacted in the last five years (2015–2019) alone, indicating a sharp rise, as outlined in a 2020 PMC study on healthcare data breaches. In 2019, 505 breaches exposed 41.2 million records across 86 countries, mainly from hacking and IT incidents. Healthcare data fetches premium prices on the dark web—a single patient's full record can sell for hundreds of dollars—making it a prime target. The average global breach cost in 2019 was $3.92 million, but healthcare averaged $6.45 million, the highest among industries; in the U.S., costs reached $15 million for breaches involving around 25,575 records. Sync.com's end-to-end encryption mitigates these risks, ensuring compliance and security for sensitive data in healthcare and beyond.
