The headline perk is lifetime access for a single payment.
It also packs an ad and malware blocker into its apps.

1. Encryption & Security Features
強力なVPN: StrongVPN wraps your データ in AES-256 encryption on every app. A kill switch cuts your internet connection if the vpn connection drops. These security features handle everyday online security without clutter.
オイスターVPN: OysterVPN also uses AES-256 strong encryption. It layers DDoS protection and an ad blocker on top. Those advanced security features give it the edge on extras.
DDoS protection is a crucial feature if you game on shared networks. Here’s how OysterVPN handles it.
2. VPNプロトコル
強力なVPN: StrongVPN supports WireGuard, OpenVPN, IKEv2, SSTP, and L2TP. You pick a vpn protocol in the settings menu. WireGuard is the best choice for speed on most devices.
オイスターVPN: OysterVPN lists WireGuard, OpenVPN, and IKEv2 as its secure vpn protocols. One review source says it doesn’t support WireGuard at all. Your app version may decide which you get.
⚠️ 警告： Reports on OysterVPN’s vpn protocols conflict. If WireGuard matters to you, check it within the refund window.
3. No-Logs Policy & Jurisdiction
強力なVPN: StrongVPN keeps a strict no logging policy. It doesn’t log browsing history, timestamps, or IP addresses. The only personal information it collects is your payment information and email address.
StrongVPN claims it never sells user data to third parties. But it’s based in the US, a Five Eyes member. Its privacy policy has never been audited.
オイスターVPN: OysterVPN follows a strict no logs policy and stores no user data. It calls this a zero logging policy. Its Irish base keeps it clear of the 5/9/14 Eyes.
⚠️ 警告： Both brands promise strict no logging policies. Neither has an audited no logs policy yet. You’re trusting each logs policy on their word.
4. Leak Protection & Identity
強力なVPN: StrongVPN includes DNS leak protection and routes lookups through its own servers. Our full StrongVPN review ran leak tests and found no IP, DNS, or WebRTC leaks.
オイスターVPN: OysterVPN prevents IP, DNS, and WebRTC leaks across its apps. Its IP leak protection hides your physical location from websites. DNS requests stay inside the vpn tunnel.
5. キルスイッチとスプリットトンネル
強力なVPN: StrongVPN’s kill switch blocks traffic the moment the tunnel fails. It does offer split tunneling, but only on Android devices. Users on the Windows or iOS app miss out.
オイスターVPN: OysterVPN’s internet kill switch stops accidental data leaks when the connection drops. Its split tunneling feature lets you choose which apps skip the VPN. It works on Windows and Android only.
💡 プロのヒント: We strongly advise keeping the kill switch on at all times. It’s your safety net on public Wi-Fi.
Here’s how the split tunneling screen looks inside OysterVPN.
6. Server Network & Speeds
強力なVPN: StrongVPN’s servers number 950+ across 30 countries, all physical. That’s more servers than OysterVPN lists. Still, it’s a small server network next to ノードVPN.
Speed results vary by source. Some tests show only a 5-7% loss on nearby servers. Others report a 20% average drop on nearby connections.
One speed test put download speeds at 31% of base, upload speeds at 13%. Gaming reports are mixed too. Some show low ping, while others note higher latency than top rivals.
オイスターVPN: Published counts for OysterVPN’s servers vary. Some sources list 400+ servers in 35+ countries. Others list 150+ servers in just 17.
Speeds hold up near home but drop about 55% on distant servers. OysterVPN’s speeds suit browsing, not competitive gaming. Pick the fastest server nearby for the best download speed and upload speed.
💡 プロのヒント: Always pick the server closest to you first. The closest server usually gives the best connection speeds on both apps.
7. Streaming & Geo-Blocks
強力なVPN: StrongVPN can safely reach major streaming platforms from anywhere. Reviews describe smooth playback with minimal buffering. StrongDNS helps on TVs that can’t run VPN apps.
StrongVPN also pitches its network as a way around online censorship.
オイスターVPN: OysterVPN routes your traffic through other countries to reach geo restricted content. It can unblock Netflix, Max, ESPN+, and BBC iPlayer. It struggles with Hulu and Disney+.
Its dedicated streaming servers help with popular streaming services. But HD playback can stutter, and 4K on long-distance servers isn’t realistic. Our full OysterVPN review covers streaming results in more depth.
⚠️ 警告： OysterVPN doesn’t work reliably in restrictive countries like China. Test it before you 旅行.
8. Device Support & Simultaneous Connections
強力なVPN: StrongVPN allows 12 simultaneous connections. Native apps cover iOS, Windows, macOS, Android, and Amazon Fire TV, plus routers. Manual setup guides handle other devices StrongVPN supports.
The Windows app and Android apps share one simple layout. Chrome OS users can grab the Android app from the Google Play Store. Like many other vpns, it has no browser extension.
オイスターVPN: OysterVPN allows five connections across multiple devices. Its desktop apps and mobile apps cover Windows, マック, iOS, and Android. There’s no native Linux app and no smart TV or console app.
💡 プロのヒント: Neither offers unlimited connections. Homes packed with phones and streaming devices get more room with StrongVPN.
9. Extras: Cloud Storage, SmartDNS & Ad Blocking
強力なVPN: StrongVPN adds 250GB of SugarSync cloud storage to every plan. StrongDNS changes your virtual location without slowing your connection. Those StrongVPN features have no match in OysterVPN.
オイスターVPN: OysterVPN’s ad and malware blocker strips trackers from your browsing activity. It works across the OysterVPN apps, so you skip extra browser extensions. It also trims bandwidth usage on ad-heavy sites.
10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | 強力なVPN | オイスターVPN |
|---|---|---|
| 無料 | ❌ | ❌ |
| Short Term | Monthly Plan: $11.99/month | 1-Month +2 Months free: $5.99/month |
| 年間 | Annual Plan: $3.97/month | 1-Year: $29.99/month |
| 一生 | ❌ | Lifetime Access: $59.99/month |
| 返金期間 | 30日間 | 30日間 |
強力なVPN: The Annual Plan gives the lowest monthly rate in this comparison. Storage and 12 device slots add real value. Watch the renewal price after year one.
オイスターVPN: The lifetime plan is the main draw. If you keep a VPN for years, paying once can beat renewals. The five-device cap limits bigger households.

私たちのレビューで取り上げられなかったこと
This comparison focused on everyday browsing, streaming, and torrenting on common devices. We didn’t test either app inside China or other restrictive countries. Router setups and the long-term reliability of OysterVPN’s lifetime plan weren’t evaluated. Our notes reflect October 2026 versions, so features and prices may change.

StrongVPN and OysterVPN target different buyers. StrongVPN is a good vpn if you want more devices, support, and storage.
OysterVPN is a decent vpn for privacy-minded users on a budget. Its Irish base and lifetime plan are real strengths.
StrongVPN isn’t the best vpn on the market. Its US base is a real trade-off. But between these two, it covers more needs for more people. If you want a strong VPN for home streaming, it delivers. If audits matter most, look at the best vpns with independent reviews instead.
