Picking the right VPN service in 2026 feels harder than ever.

Dozens of VPN providers promise speed, online privacy, and unblocking power.

Two popular options are Surfshark VPN and Oyster VPN.

Surfshark is a premium VPN with 3,200+ servers and unlimited device connections.

OysterVPN is a newer provider from Ireland with a rare lifetime access option.

Both VPN services use AES-256 encryption and support secure VPN protocols.

But once you look past the basics, the two VPN providers feel very different.

I tested Surfshark vpn vs Oystervpn for three weeks side by side.

I ran speed tests, checked streaming services, and pushed the security features.

機能比較

Let me compare Surfshark VPN and OysterVPN across 9 key features.

This is where the real differences between the two VPN providers show up.

1. サーバーネットワーク

Server count drives both connection speeds and access to geo restricted content.

More VPN servers means less crowding and more nearby server options.

2. スピードとパフォーマンス

VPN speed decides your streaming quality and download speed.

I ran each speed test on the fastest server and on distant servers.

3. プライバシーとセキュリティ

Online privacy is the whole point of a good VPN.

Both VPN providers ship strong security features but with very different track records.

4. ストリーミングとブロック解除

Most people buy a VPN to unblock streaming services from other countries.

Here is how each VPN app handles popular streaming services.

5. デバイス接続

Device limits affect how many devices you can protect at once.

This is one of the biggest gaps between the two VPN providers.

6. Split Tunneling and Advanced Security Features

The split tunneling feature lets you choose which apps use the VPN tunnel.

Each VPN service handles this crucial feature differently.

7. Unique Features and Extras

Both VPN services pack extras beyond standard VPN features.

Quality and depth of those extras decide the real value gap.

8. Platform Support and Apps

A VPN is only useful if it runs on all your devices.

Mobile apps, desktop apps, and browser extensions all matter here.

9. 価格とコスト

What Our Review Didn’t Cover

This Surfshark VPN review and OysterVPN review focused on individual users and small households. I didn’t test enterprise SSO, bulk licensing, or VPN configuration for 仕事 networks. Edge cases like China access for OysterVPN and obfuscated servers performance in highly restrictive regions weren’t fully evaluated. Findings are based on the March 2026 versions of both VPN apps.

最終評決

Surfshark VPNとOysterVPNは、全く異なるタイプのユーザーを対象としている。

Surfshark is a mature premium VPN with a massive server network and audited online security.

It supports unlimited devices and unblocks nearly every streaming service.

OysterVPN is a newer VPN provider that competes on price with its rare lifetime access option.

It has solid security features but a smaller server network and no audit.

OysterVPN is a strong pick for budget buyers who want a cheap VPN for everyday browsing and torrenting.

The OysterVPN subscription lifetime plan is tempting if you want one-time savings.

But for speed, streaming, and proven security, Surfshark is the clear winner.

The 2-year Surfshark subscription at $1.99/month is hard to beat for value.
