**Logitech Flow and Mouse Without Borders state that connections are encrypted, though the method of encryption is not published.

"TLS (the successor to SSL) is well known as the protocol that encapsulates HTTP and SMTP to provide secure web browsing via HTTPS." "It is important to note that AES should not be used by itself, but in a cipher chain. The most common method is to use an initialization vector (IV) to scramble the unencrypted data before being encrypted. This ensures that two identical messages don’t result in identical encrypted data, which prevents someone from inferring patterns even from the encrypted data stream." - AES vs TLS

Synergy was born out of frustration with KVM switches

The “KVM switch” was traditionally the only way to connect one set of peripherals to multiple computers. Invented in the 1980s, KVM switches are physical boxes with cables running to each computer. They’re far from seamless. Synergy was created to do better.
