What speed actually means for VPN users

Throughput: The amount of data you can transfer per second, usually measured in Mbps or Gbps.
Latency: Time for a single data packet to travel from your device to a server and back, measured in ms.
Jitter: Variability in ping times, which can affect real-time apps like video calls or gaming.
Packet loss: Percent of packets that don’t reach their destination, leading to retries and slower performance.

When you run a speed test without a VPN, you’re measuring your raw internet path from your device to the test server. Turn on a VPN, and all your traffic is wrapped in an encrypted tunnel, which adds processing and routing steps. This can increase latency and sometimes reduce peak throughput, but it also masks your traffic from local networks and provides security on untrusted networks.

How Zscaler changes your connection

Zscaler works at the enterprise level, often routing traffic through large-scale proxies and security checks. It’s designed to protect users on corporate networks, especially when accessing SaaS apps and the internet from remote locations.
Because Zscaler inspects traffic, you may see higher latency and more variability in speed tests compared to a direct connection.
Zscaler can route traffic to specific security services cloud firewall, data loss prevention, web filtering. This corporate routing can add hops and processing delay.

Key takeaways:

Expect higher latency with Zscaler than a direct connection, especially if you’re farther from the Zscaler data centers.
The security benefits outweigh the slight speed hit for most business use cases, particularly when accessing sensitive apps.

How to run reliable speed tests with a VPN

Baseline test no VPN: Run 3–5 tests at different times of day to get a feel for your typical speeds.
VPN on: Run the same tests with the VPN enabled, choosing different servers if possible.
Repeatable tests: Use consistent test servers or domains speedtest.net, fast.com and ensure you’re not downloading updates or streaming during tests.
Test in multiple locations: If you have access to different VPN exit points or corporate proxies, compare results across regions.
Real-world checks: Open a website, stream a video at 1080p, or join a video call to gauge perceived performance beyond raw Mbps.
Track both directions: Measure download and upload speeds, latency to test server, and jitter. Some tests show ping, others show only average latency.

When testing with Zscaler specifically, you’ll likely see:

Higher baseline latency to global servers due to proxy routing
Variable throughput depending on time of day and load on Zscaler services
Potentially more consistent performance on corporate apps protected by Zscaler due to optimization

Common testing formats to use

Quick 5-minute test: 3 tests with VPN on and off, record averages
15-minute stress test: Longer period testing with multiple server choices

Data and statistics to guide expectations

Typical consumer VPN impact: 10–40% drop in throughput on average, but can be more or less depending on server distance and encryption protocol
Latency shift: 20–100 ms additional RTT is common when using a VPN, with higher values when routing through a corporate security platform
Zscaler-specific reality: Enterprises report variable latency based on policy enforcement points, with some users seeing relatively stable performance for web apps and SaaS, while more bandwidth-heavy tasks take a hit

If you’re curious about current trends, here are sample ranges you might see in common conditions these are illustrative and can vary by geography, ISP, and server load:

Home broadband fiber: Direct speedtest 300–1000 Mbps; VPN on 150–700 Mbps, latency 10–25 ms direct vs 40–120 ms with VPN
Cable/DSL: Direct 20–200 Mbps; VPN on 5–100 Mbps, latency 20–60 ms to nearby test servers
Mobile 4G/5G: Direct 5–100 Mbps; VPN on 1–50 Mbps, latency 30–120 ms

Factors that impact VPN speed

Server distance and load: Closer and less congested servers give better speeds
VPN protocol: OpenVPN, WireGuard, IKEv2 each have different performance profiles
Encryption overhead: Stronger ciphers add CPU load, which can slow things down
Local device performance: CPU and memory limits affect encryption and tunnel handling
Network path quality: ISP peering, backhaul capacity, and intermediate proxies matter
Zscaler policies: Security checks, URL filtering, and data loss prevention can add processing time

Protocol comparison at a glance

WireGuard: Fastest and simplest, good balance of security and performance
OpenVPN: Flexible, widely supported, can be slower depending on config and hardware
IKEv2/IPSec: Solid performance, good stability on mobile
Zscaler proxy: Enterprise-grade security, may add more latency but improves protection

Practical optimization steps

Choose the closest VPN server: Start with a nearby city or regional server before attempting long-distance routes
Switch protocols: If your client supports multiple protocols, try WireGuard first, then test OpenVPN if needed
Disable unnecessary features: In some VPN clients, disabling “kill switch” or leak protection won’t help speed, but disabling extra encryption layers can sometimes help in trusted networks not recommended for public networks
Enable split tunneling where available: Route only critical traffic through the VPN, leaving bulk traffic to go direct when permissible
Optimize your local network: Use a wired connection if possible, ensure routers are not choking throughput, and reduce competing devices during tests
Update firmware and software: Keep your VPN client, router, and device OS up to date for performance and security improvements
Check your downstream apps: If you’re testing speed for a specific app video conferencing, cloud storage, test those paths directly
Test during off-peak hours: VPN performance can vary with ISP congestion; test early mornings or late nights for baseline behavior

Security trade-offs when testing speed

Encrypting traffic adds overhead: While speed can dip, you gain privacy and protection
Proxy checks can slow traffic: Zscaler inspects traffic for malware and policy compliance, which is a security win but can impact speed
Always balance risk vs. performance: For sensitive data or untrusted networks, the security gained by VPNs and enterprise proxies usually outweighs the minor speed decrease

Real-world scenarios and benchmarks

Scenario A: Remote worker using corporate Zscaler proxy on home Wi-Fi
- Direct test: 950 Mbps down / 980 Mbps up, 6 ms latency
- VPN on WireGuard, nearby server: 700 Mbps down / 720 Mbps up, 25 ms latency
- VPN on with Zscaler proxy: 420 Mbps down / 480 Mbps up, 60–85 ms latency
- Takeaway: For general browsing and SaaS, performance remains solid; for video calls or large file transfers, expect some buffering or longer sync times
Scenario B: Public Wi‑Fi with a consumer VPN
- Direct test: 120 Mbps down / 20 Mbps up, 15 ms latency
- VPN on: 40–60 Mbps down, 6–12 Mbps up, 60–100 ms latency
- Takeaway: Public networks are where VPNs shine for security, even if speed dips
