“All content (including file attachments) is end-to-end encrypted so that even SpiderOak can’t read it. Easy to use and visually appealing.”
“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).”
“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. Let's just say (Semaphor) is like Slack, but WAAAAY more secure.”
“One nice feature of Semaphor that Slack doesn't have: the ability for individuals to pay their own way.”
Privacy isn’t the only perk of Semaphor. Whether you are busy working on a project, organizing an event, or creating a discussion around a special topic, use Semaphor to help. Get started by creating as many Teams and Channels as you want. Then invite your friends, family, or coworkers. Start communicating and collaborating securely. (Bye-bye email!)
You can even create your own personal channels for saving notes, links, files, ideas, and anything else you may need. You'll never need to email a file to yourself again.
Your ideas matter! Protect them.
Semaphor retains your conversations and data from day one. If you ever need to go back and find a file or conversation, use the search bar — even if you’re not connected to the internet. Standard and Pro accounts have access to unlimited conversation history. Because Semaphor is an application downloaded to your device, and not in a web browser, search is crazy fast. If you put us up against the competition, we'll beat them hands down. Other perks of being an application on your device include multi-file uploads, concurrent downloads (you can start downloading a file before it's even finished uploading!). Large file support up to 2GB.
No matter what you're working on or searching for, you can stay productive on your mobile device or at your desk. Unlock unlimited search history for only $9/month.
