It can. Routing traffic through a VPN server adds an extra hop, which sometimes increases latency, especially if the VPN server is far from the actual webinar server.
Webinar Glossary
VPN
A VPN, or Virtual Private Network, is a secure connection between a device and a server that allows a user to browse the internet anonymously.
What is a VPN?
A VPN, or Virtual Private Network, is a secure connection between a device and a server. The connection allows a user to browse the internet anonymously. Without a VPN, internet activity can be intercepted and viewed by others.
VPNs can be used to bypass location restrictions, protect privacy, and encrypt data while surfing the web. They are often used for booking hotels and flights, streaming content that is unavailable in certain countries, and remote working.
How does a VPN work?
A device’s IP address makes it easily traceable. When connected to a VPN, the IP address is masked. VPNs can be compared to tunnels between two devices that allow websites to be accessed privately. Internet traffic appears to come from the VPN server rather than the device being used.
How do VPNs impact your webinars?
VPNs can block the ability to access webinar software. Webinar organizers should always check the software’s technical requirements to make sure this isn’t the case. The best webinar software will let users run connection teststhat troubleshoot any potential issues that could impact connection.

Frequently Asked Questions
Does using a VPN slow down a webinar connection?
Should webinar organizers ask attendees to disable their VPN?
Only if attendees are having connection trouble. For most attendees, a VPN causes no issues, so it's better to mention it in troubleshooting guidance rather than upfront instructions.
Can a VPN block access to a webinar entirely?
In rare cases, yes. Some corporate VPNs restrict outbound connections that a webinar platform needs, which is why checking technical requirements matters for attendees on managed networks.
Is a VPN the same as a firewall?
No. A VPN encrypts your traffic, while a firewall controls what traffic is allowed in or out of a network.
