BYOD and BYOM Security

There are several key differences between “bring your own device” (BYOD) and “bring your own meeting” (BYOM) and how the two approaches are applied at workplaces. 

For BYOD, the Host Receiver coordinates screen casting from various devices that have direct reception from a transmitter (i.e., BYOD or Wireless Presentation System button). BYOD has user devices talking directly to the Host Receiver, which then delivers mirrored presentation data to a large display. The presentation data can be limited to only the people in the room, and you don’t even need to connect to the internet if you use a wireless presentation system (WPS) like the BenQ InstaShow WDC series

For BYOM, the Host Receiver doesn’t just passively receive data from a transmitter (TX), but also needs to allow BYOM devices such as laptops access, so those may collect all the data transmissions connected to the Host Receiver, including all-in-one video conferencing devices and the display.  

That is to say, while in BYOD devices talk to a Host Receiver that mirrors them onto one big screen, in BYOM the Host Receiver allows devices to mirror or cast not just to a big screen, but requires more permissions for data security and control over who can access the Host Receiver, and thus creates more security risks.

In a hybrid meeting, through accessing the data in the Host Receiver, the BYOM laptop (i.e. BYOM Host) can synchronize the casting of the in-room meeting onto the local screen with remote participants. However, if any laptop can freely access the data in the Host Receiver, the control of confidential meeting data becomes challenging. To ensure effective control of sensitive information, a security mechanism can be implemented between the Host Receiver and laptops.

Therefore, to ensure data security in BYOM setups, controlling access becomes paramount. Implementing WPA2-Enterprise to regulate laptop access is crucial to prevent unauthorized entry into the Host Receiver.

Setting Up BYOM with Three Layers of Security

To ensure data security, there are three layers for BYOM protective set up recommendations:

Layer 1: Indirect Connection in the Host Receiver

An indirect connection is the first layer of security for BYOM. Companies aiming for optimal security and protection may opt for indirect connection.

In this setup, as the diagram shows, you establish an indirect connection where the Host Receiver and employee laptops are linked to the intranet rather than via a direct connection to the internet. The intranet can provide the firewall and the Active Directory (AD) server for security and protection against unauthorized snooping or intrusion.

Layer 2: Activate a WPA2-Enterprise SSID

The second protective BYOM layer is enabling WPA2-Enterprise with setup for guest SSIDs. With that, you can have a separate SSID for employees and a dedicated SSID for guests, with different access privileges to prevent unauthorized data accessing and sharing. 

Layer 3: Enter Pin code before Connecting to Host Receiver

The third layer is the use of a pin code. BYOM users need to input a pin code in order to get access to the Host Receiver. The pin code is only given to people that are in the meeting room itself, so this way ensures presentation data remains limited to only the people in the room. If you have guests joining you locally, simply connect them with a WPS button so you don’t even need to connect to the internet to mirror to the big screen.

For guest laptops, a simplified approach is recommended. Provide guests with a BYOD or WPS button for content casting, eliminating the need for network connectivity. Additionally, configuring a guest SSID adds an extra layer of protection.


For InstaShow VS20 users, you can upgrade to the latest firmware (version 1.04) and InstaShow VS Assist App (version 1.2.0).

In Conclusion

For BYOD, users transmit one way to the Host Receiver, which then mirrors content to a large screen. But there’s no “crosstalk” among user devices, and users do not have access to the Host Receiver’s resources. Like with the BenQ InstaShow WDC series, which offers a dedicated BYOD, or WPS button that’s free from the internet so presentation data can be limited to only the people in the room. This ability offers sufficient security for BYOD situations. 

For BYOM, communication is two-way, with at least the BYOM host laptop being able to access the Host Receiver and other devices that take part in the meeting. Therefore, the three layers of security described above must be in place. We strongly recommend you implement the three layers we detailed, all of which are supported and enabled by InstaShow VS20 for the best possible organizational security, confidentiality, and peace of mind.
