Networks / Wi-Fi for small companies

Of course!
‍
When setting up an enterprise Wi-Fi, it is important to differentiate between employees and external users. External users must not have access to the internal resources of your enterprise.
‍
The implementation of a guest portal gives you the possibility to differentiate the 2 types of connection, but also to inform your guest about the use of internet.  
‍
At Cactus Info, this solution is proposed during the implementation of a Wi-Fi system, plus we personalize this portal with your logo!

It is an element of protection of the network.
The purpose of a firewall is to control the traffic between different trusted zones (Internet, workstation network, server network…)
A filter system is implemented to let pass only the necessary traffic for the use of your IT system.
This element can be hardware or software.

To keep it simple, it is a secured access to the network of your enterprise.  
With only a basic internet connection, the user can access in a secured manner to the IT resources of your company.
This connection is encrypted and requires the use of a VPN-client from the workstation of each user.
A firewall is necessary to realize this type of connection.  

Yes it is, this is actually what I use myself for my business land line number!
There are many advantages like being able to dispose of your land line number at any time and with one simple data connection on your smartphone.  
It is also possible to use your number when travelling abroad.
