What is Siilo?

Siilo is the secure messenger for healthcare. Medical professionals and teams can communicate and share information in a secure, encrypted environment. It is our mission is to connect you with your peers to discuss challenging cases together, share the latest news and views, and stay on the ball when a patient requires that extra attention during your busy work schedule.

What are the requirements to run Siilo?

Siilo is compatible with the majority of devices, OS and browser versions. The mobile app supports iOS version 10.0 or Android 4.4 (KitKat) and higher. Unfortunately Android Go is not currently supported.

The web messenger can be used on Chrome, Safari, Internet Explorer, Edge, Firefox, and Opera. Please note that for security reasons only Internet Explorer 11 and above are supported.

What can I do with Siilo?

You can use Siilo to manage your workflow, or manage care for your patients. Siilo is also used for medical crowd sourcing, i.e. asking a group of trusted peers for advice on challenging cases. Siilo can also be used as a portfolio tool and share cases for educational purposes.

Why are you called Siilo?

Siilo is Finnish for "silo." Silos are vertical structures that carry one-of-a-kind material, e.g. grain. Figuratively speaking, silos are groups of people from one department, profession or background. In (healthcare) management, the word silo is oftentimes negatively used to describe a group of people who do not share information with others. In medicine, silos are both a curse (silos prevent collaboration) and a blessing (sensitive information does not flow freely). 

Siilo contains two i's referring to our mission to strike the perfect balance between collaboration and information security between classic silos in healthcare. In addition, Siilo is our acronym for Secure Internet Information Liaison Or something like that.

Use of Siilo.

How do I start a conversation with a colleague?

In the ‘chats’ screen you are able to click on every person that is automatically added to your chats list through the synchronisation of the contact list on your phone. If the person is not there, you can go to the ‘spaces’ tab and choose 'Connect with colleagues', where you can send an invite.

How do I start a new group conversation?

In the ‘chats’ tab you can click the ‘compose message’ icon. After clicking that, you can click on ‘new group chat’. Then you can search for people you want to add, click next and come up with a name and picture for the group.


Where does Siilo store my pictures and video's?

Pictures and video's will be stored encrypted within the app on your phone. It is not possible to access these files without your private key.

How do I anonymize a picture?

You can blur faces, special tattoos and names or birth dates with tools within the app. After opening or snapping an image, you can select the "edit" icon. You can blur parts of an image, or place an arrow. On Android you can tap "undo", or "undo all." On iOS you can double-tap to remove a blur or an arrow. Tap "save" before sending the image to your colleague.

Security and privacy.

Why is a PIN-code required to open the app?

The PIN-code is to block unwarranted trespassers when your phone is unlocked. When one enters the code incorrectly 3 times, the app will be blocked for 3 minutes. After that, the app will be blocked for 15 minutes after the PIN-code was entered incorrectly. You can always enter the app directly during these blockages with your fingerprint.

How do I know that my messages are encrypted?

We do not want you to notice anything of our high-level encryption. So you will not notice that this encryption happens all the time: when you send a message, when you open a new message, every time you open the app, when you go to the pinboard, etc. Only when you send a message to a user that uninstalls and reinstalls the Siilo app on their (new) phone, he/she will be unable to decrypt your message. However, when you resend that message, that user can decrypt the message again.
