What is On Premise Messaging?
On-premises messaging refers to a type of messaging system where the servers and infrastructure for sending, receiving, and storing messages are hosted within an organization’s own physical location or data center. This means that the messaging service is deployed and operated internally, rather than relying on external or cloud-based messaging servers..
What Is an On Premise Chat Software?
On-prem chat solution is a type of communication platform that is installed and hosted locally on your organization’s premises, rather than being hosted on a public cloud platform or remote data center.
This typically means that your business has full control over the infrastructure, hardware, and software applications, including their performance, security, and maintenance.
Why Should You Choose On-premise Chat Solution For Your Business?
Well, there are hundreds of explanations about this deployment option across the internet. But the one question that you’ll need an answer for is – Is on-premise chat solution right for your business?
Let’s rule it out
1️⃣ Enhanced Security
Building a self-hosted private chat server can be your best option if you are looking for enhanced data security for your messenger application.
You will basically have complete control over your data, so you can implement your security protocols to ensure it stays secure.
2️⃣ Customization
Your business is unique and it requires specific chat requirements to deliver the experience your target users expect.
In this case, you can customize or personalize the chat solution as much as you want to meet your specific needs
Guess what? you can also integrate it with other business applications, and add unique features that your users will love.
3️⃣ Compliance with Industry Regulations
If your organization must comply with strict data privacy and security regulations, then hosting your enterprise messaging app on your own can be your ideal choice.
This means, you have full control over your communication data, which can help you meet compliance requirements as per your need.
4️⃣ A Great alternative to cloud-based chat solutions
If you need to build a messenger for business and government, or healthcare organization, financial institution, or indeed a company with legacy systems that cannot be easily integrated with cloud-based chat solutions, then creating your own chatting server would be a wise thing to do.
How Do On-premise Chat Software Work?
Setting up an scalable on-premise solution for your dedicated chat apps typically means that you are hosting your app/ software on your own servers that are physically located with your organization’s own premises.
This means that the organization has complete control over the instant messaging software and the data it generates. So let’s say you have hosted your app on your own server, you can expect the following to happen.
When a user sends a message through the on-premise chat solution, the message is securely transmitted within the organization’s network without leaving the premises.
This ensures that the communication data remains private and secure.
Let me explain how self-hosting work in a few simple steps:
1. Installation
The first step in setting up a server on your own premise.
This can typically be done by downloading the software from the vendor’s website and following the installation instructions.
2. Configure the solution as per your brand/ business requirements
Once the software is installed, it needs to be configured to work with the organization’s network and infrastructure.
This can include setting up user accounts, creating channels, and configuring security settings.
3. Register your users
Once the software is installed and configured, users can access it through a web browser or a dedicated app installed on their devices.
They can then log in using their credentials and start using the messaging software to communicate with their colleagues.
4. Access app data from your own servers
All communication data generated through the ready-made chat software is stored on the organization’s servers. This includes messages, files, and other media exchanged between users.
5. Customize the security & privacy of your app
Hosting your platform on-premise typically offers robust security features for your chat apps, such as two-factor authentication, encryption, and access controls, to ensure that the communication data remains private and secure.
6. Set up a maintenance routine
As with any software, your chat solution requires ongoing maintenance to ensure that they continue to function properly. This can include applying software updates, monitoring system performance, and addressing any issues or errors that arise.

On-premise chat software refers to the type of hosting where your app is installed on your own hardware infrastructure. On the other hand, cloud hosting refers to deploying your app on a third-party server, and is accessed through a web browser.
Also, an on-premise messaging software gives you complete control over your chat app’s data, hardware and software. Whereas in a cloud-solution, your vendor will take care of your platform’s hosting and maintenance.
What is the meaning of on-premise?
“On-premises” or “on-prem” is a way of installing software directly on users’ computers using CDs or USB drives, while “off-premises” means the installer can be downloaded from the internet.
For example,
A company installs a customer relationship management (CRM) software on servers within its own data center. This is considered an on-premises CRM solution.

What is on-premises vs cloud?
In On-premise hosting, the data centers are installed on the company’s own hardware infrastructure. Whereas cloud servers are owned and managed by providers and are accessed through interfaces and web browsers.
What is hosted vs on-premise?
A hosted solution lets you access your app’s data from anywhere, anytime. It can make your systems work as per your convenience. Whereas on-premises data centers are built in the organization’s premises.
Is on-premise more secure than cloud?
Cloud security is safer than on-premise when you do not have enough tools or human resources to invest. Cloud security has segmentation whereas on-premise servers have user workstations. And most phishing and email attacks happen through workstations.
