How a VPN affects your speed

  • VPN basics: A VPN creates a private tunnel between you and a VPN server. Your traffic is encrypted, then routed to its destination. This extra hop adds latency.
  • Encryption overhead: Stronger encryption protects data but costs CPU cycles. If you’re on older hardware or a slow device, you’ll notice more delay.
  • Server distance matters: The farther you are from the VPN server, the higher the latency and the potential for packet loss.
  • Bandwidth limits and congestion: VPN providers pool many users on shared servers. During peak times, speeds can dip.
  • Protocol differences: OpenVPN, WireGuard, IKEv2—each has its own balance of security and speed. WireGuard tends to be faster on many networks.
  • Local network and device influence: Wi‑Fi signal quality, router performance, and background apps all affect your measured speed.

What Zscaler really does for your connection

  • Zscaler as a security gateway: Zscaler acts as a cloud-based secure web gateway. It inspects traffic to block threats, enforce policies, and provide secure access.
  • Impact on latency and throughput: Traffic may route through Zscaler’s cloud services, adding a few milliseconds to each hop. In some cases, it can be negligible; in others, noticeable.
  • SSL inspection trade-offs: Deep packet inspection of TLS traffic increases security but can add processing overhead if enabled.
  • Use cases: Enterprises use Zscaler to provide safe remote access, secure web browsing, and threat protection for SaaS apps.
  • End-user experience: If your organization uses Zscaler, you may see slightly higher latency but improved security and policy compliance.

How to test your speed with VPNs and Zscaler in mind

  • Baseline speeds: Start by testing your speed without a VPN to know your home network’s natural performance.
  • Test with VPN connected: Try different servers and protocols to find the best balance of speed and security.
  • Speed testing tools: Use Ookla Speedtest, Google’s speed test, and measurement labs from your ISP for cross-checks.
