Hi everyone,
I’m currently learning cybersecurity concepts and practicing in lab environments where I often use a VPN to simulate secure remote access and test different network scenarios.
While working through different setups, I’ve noticed that VPN usage can sometimes affect latency and stability, especially when accessing remote lab machines, downloading resources, or running cloud-based tools.
I understand that this is expected due to encryption overhead and routing changes, but I’m trying to better understand how professionals handle VPN usage in real-world security environments without impacting performance too much.
I also came across this overview that explains VPN protocols and performance behavior in a clear way: https://vpnmag.net/ — it helped me understand differences between WireGuard, OpenVPN, and IKEv2 in practical use cases.
So I’d like to ask the community:
- How commonly are VPNs used in cybersecurity training and production environments?
- What are best practices for minimizing performance impact while maintaining secure access?
- Are there preferred VPN setups for labs, remote access, or SOC environments?
Any guidance or real-world experience would be greatly appreciated.
