“All content (including file attachments) is end-to-end encrypted so that even SpiderOak can’t read it.”
Motherboard
“If an attacker were to gain access to every corner of SpiderOak's corporate systems, it wouldn't let them read the conversations of the firm's customers. If you want to enjoy the benefits of collaboration apps and don’t want to give up on your privacy, you might want to consider (Semaphor).”
The Daily Dot
“Slack, Hipchat and other collaboration tools are the cool kids these days. And while they do a lot well...there's something missing that can cost you your business. Privacy.”
Inc
“Use Semaphor for collaboration. Semaphor allows teams of users to share files and create private chat rooms that are encrypted individually.”

  • Scalability as needed
  • Onsite training & tier 1 support (assisted deployment optional)

Secure-by-Default.

Reduce your risk with our No Knowledge architecture. Because our software encrypts every piece of data before it ever leaves a computer, we can never know the types or content of your files.

Everything we store is encrypted end-to-end (at-rest and in-transit). You alone have sole ownership and complete control of the keys to unlock your data. Keys only reside on user devices.

Never pre-encrypt a sensitive document or worry about a third party seeing your work. We believe privacy is the best security and built all of our products for enterprise with this in mind.
