What is the difference between Messagenius and Telegram, WhatsApp or Messenger?

From the security perspective, Messagenius offers on-premises installation and gives complete data ownership to the client. In terms of the UI and UX, Messagenius offers all the same intuitive and friendly UI/UX together with additional customizable features for boosting the user experience and optimizing the communications within the app.

Can messages be archived?

Yes. They are automatically archived, the retention of the messages is configurable by the client. Passengers can choose to save their individual chats. The cruise line or app operator can also archive all chats for history and security.

Do all the contacts/employees from the contact list can contact each other? Can a worker on-field contact the CEO of the company, if they’re on the same contact list? Can it be prevented somehow?

Messagenius offers complete customization of our product. This means you can decide how users in your organization can contact one another. We achieve this through Lightweight Directory Access Protocol (LDAP) and Active Directory functions. Thus, we can organize all the contacts in your company based on their roles. A standard configuration allows lower level employees to reach out horizontally, but limits their vertical communications. Higher level managers can communicate with anyone in the company. However, this is fully customizable, so if your business would benefit from a different organization, then this is possible to achieve.

If the CEO can look and monitor the chats between employees, can the other employees do the same?

User access and data review can be configured in any way that suits your company’s operating requirements. The software can be configured so that only one person has access for oversight. Equally, it is possible to configure the software so that data can be reviewed and managed by multiple people, such as the Chief Information Officer or Chief Technological Officer.

What is a temporary 007-like chat?

A temporary secure chat is a completely private chat between two people that cannot be monitored and disappears as soon as the business is concluded. These chats are designed to happen between two endpoints, such as two mobile devices or two computers. They are not transmitted through any 3rd party servers, software, or platforms. Once the conversation is finished, the data is erased and there is no record of the conversation.

What is a black hole chat?

By Black Hole Chat is a disappearing chat or a single message that can be permanently and irrevocably destroyed. To make it work, you send a message with a timer. Once the message is opened, the timer begins. After the timer finishes, the message is destroyed and disappears forever. Since it has not passed through any other communications system, like a 3rd party instant messaging platform, every record of its existence can be eliminated.

What is a “black box” chat?

Black box chat is a Messagenius feature that records every message and chat. When a message is sent, the sender, recipient, and contents are recorded. Messages sent within a black box chat also come with a mandatory proof of receipt. Once the message and its data have been created, the recorded data cannot be erased.

Does Messagenius have SSO (Single Sign-On)?

Yes, we offer built-in APIs to enable SSO (Single Sign-On) for customers.

How can I provide access to a new user, or delete a user from the system?

In the beginning, you can provide a list of your users, including their names and email addresses. We will create accounts and credentials for your users so they can access the system. After installation, user management can be controlled by the people to whom your organization has given this permission.

Why is Messagenius better than WhatsApp, Skype, Telegram, or Slack?

Only with Messagenius you own the data and can control communication, because Messagenius is directly installed on your company’s server, and our customizable features allows you, as the top-manager, monitor the data exchanged as the supervisor. Plus, we adjust to our client’s needs, so we can add/remove/change particular features upon request being very flexible and customizable. Also we have the patented one-tap voice message system, which allows you to send voice messages with 1 tap (instead of 3 as in any instant messaging app). None of the apps above (WhatsApp, Skype, Telegram, or Slack) allow you to do so, because they are designed in a way to make you adjust to them, not them adjusting to you. And most importantly, none of them allows you for data ownership and control, so all your data exchanged through those apps is not protected at all.

What are the disadvantages of Messagenius?

We are biased, but we don’t think there are any disadvantages of Messagenius. One reality many enterprises face is the time to deployment. Messagenius, in its fully customized stages, is not an “off the shelf” product. Companies using a fully tailored installation of Messagenius may have to plan for a short period of development prior to installation.

What are the special features for top managers? What can you offer me?

Managers can use several specific features to improve communication and coordination: – Black box chats are available to make a permanent recording of conversations. – Black hole chats are the opposite, and allow conversations to be permanently deleted. – Broadcast messages can be sent to everyone in a group or the entire organization. Many other features can be customized for your use. If there is a special function you would like to improve your management or communication, then Messagenius can deliver it for you.
