The commodity

VPNs provide a convenient solution for employees and incredibly remote users to easily access your company’s network without requiring a physical presence while keeping private networks and corporate resources secure.

Communication over a VPN provides a higher level of security than other remote communication methods by restricting unauthorized access to private networks. The actual geographic location of users is protected and hidden on public or shared networks, such as the Internet.

Simplified administration

Adding new users or user groups to networks is easier using flexible VPN software tools. This is ideal for businesses whose scalability exceeds budgets, as network footprints can often extend without adding new components or defining complex network configurations.

Are there any downsides to using VPNs?

The effectiveness of a VPN depends on the other pieces of your network infrastructure. Here are the factors that can cause VPN performance issues:

Setup Security Risks

Designing and implementing a VPN can be complex. If you doubt its operational security, consider hiring a knowledgeable network security professional to verify that the VPN’s security has not been compromised.


Since VPN connections work over the Internet, you should choose an Internet Service Provider (ISP) that guarantees excellent service with minimal, if any, downtime.


Technical incompatibility issues may arise when there is a need to add new infrastructure or create configurations, especially when adding new products from different vendors.

Low connection speeds

If you use a VPN client offering free VPN service, the connection speed may be slow, as these providers often need high-speed connections. Consider whether the speed is suitable for your business needs.
