⚡ 簡単な評価:
- 価格: Private Internet Access starts at $2.03/month. OysterVPN starts at $5.99/month.
- 最適な用途: PIA for privacy on a budget across all your デバイス. OysterVPN for lifetime access and simple streaming.
- 主な違い： PIA has a strict no logs policy audited by Deloitte. OysterVPN has never had a third-party audit.
- サーバーネットワーク: 35,000 servers in 91 countries versus roughly 400+ servers in over 35 countries.
- 私たちのおすすめ： Private Internet Access, because it gives you unlimited simultaneous connections at a lower entry price.
安いほど VPN service here is also the bigger one.
Private Internet Access asks $2.03 a month on its longest plan.
OysterVPN asks $5.99 a month to start.
Yet PIA runs 35,000 VPN servers and Oyster VPN a few hundred.
So price is not what separates these two vpn providers. Proof, speed, and device limits are.
概要
This Private Internet Access vs Oyster VPN comparison covers pricing, 安全 features, speeds, and streaming.
We read both privacy policies, both pricing pages, and public user reviews.
Our writers also spent hands-on time with each vpn app.
それらのメモは、以下の「チームが気づいたこと」のセクションに記載されています。
By the end you will know which virtual private network fits you.
プライベートインターネットアクセスとは何ですか?
Private Internet Access is a vpn service that hides your real ip address.
It wraps your internet traffic in an encrypted vpn tunnel.
Every private internet access review lands on the same fact: cheap and big.
Your ISP sees nothing but noise, which also blunts ISP throttling.
Wondering how many servers it runs? Around 35,000 across 91 countries.
PIA covers Windows, Mac, Linux, iOS, and アンドロイド from one account.
There are browser extensions for Chrome and Firefox, plus a command line app.
The pia app is also on the Apple App Store for mobile devices.
Here is a walkthrough of how the private internet access vpn works day to day.
プライベートインターネットアクセス
A cheap vpn with a strict no logs policy verified by Deloitte. You get unlimited simultaneous connections and unlimited bandwidth. Current private internet access deals start at $2.03 a month.
プライベートインターネットアクセス料金
PIA offers three plans. No hidden costs and no paywalled features.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 2年4ヶ月 | 月額2.03ドル | 予算内で長期的なプライバシー保護を実現 |
| 6ヶ月 | 月額7.50ドル | A medium commitment |
| 1ヶ月 | 月額11.99ドル | Short trips and quick testing |

無料トライアル: No free trial. You sign up and pay first.
返金保証: Yes. A 30 day money back guarantee lets you test the service risk free.
📌 注記： Private Internet Access does not raise subscription prices at renewal. Most vpn providers do. Every plan includes the same features, so a cheaper term never means a weaker vpn connection.
⚠️ 警告： PIA also lists $11.95 monthly, $39.96 yearly, and $79 for three years elsewhere. Our table follows the CSV pricing. Check the cart total before paying.
プライベートインターネットアクセスの主な利点
What you actually get for the money:
- デバイス数無制限： PIA allows unlimited simultaneous connections. Most other vpn providers cap you at five to ten.
- 監査済みのプライバシー： Deloitte verified the strict no logs policy through multiple audits, and transparency reports are published quarterly.
- オープンソースアプリ： Anyone can inspect the code, which is rare among vpn services.
- US Coverage: Servers in all 50 states. Good for US sports, banking, and online gaming.
- MACE Blocking: A built-in ad and tracker blocker working at the DNS level, so ads die before they load.
- 公共Wi-Fiの安全性： PIA encrypts your internet connection on shared networks. Your connection data and identifying data stay away from criminals in cafés and airports.
- 追加ツール: Multi-hop routing, port forwarding, and Identity Guard breach monitoring.
私たちのチームが気づいたこと
私たちの 作家 tested Private Internet Access on a laptop and a phone. We tested PIA across US, UK, and Asian server locations, because pia’s servers behave very differently by region. Here is what stood out from that hands-on time:
プライベートインターネットアクセスのメリットとデメリット
✅ メリット
- Long-term plans start at $2.03 per month with no renewal price hike
- Unlimited simultaneous connections cover every device in the house
- Strict no logs policy independently verified by Deloitte audits
- 35,000 servers in 91 countries, including all 50 US states
- Split tunneling, multi-hop, MACE, and port forwarding for power users
❌ デメリット
- Average download speed loss of 49% hurts bandwidth-heavy work
- Streaming access is inconsistent, and BBC iPlayer can fail
- The one month plan at $11.99 sits above the industry average
Oyster VPNとは何ですか?
OysterVPN is a smaller vpn provider based in Dublin, Ireland.
Ireland sits outside the 5/9/14 Eyes Alliances, which helps user privacy.
The service encrypts your internet connection and hides your physical location.
Most oystervpn review coverage leads with the lifetime deal, and fairly so.
Its network is roughly 400+ servers in over 35 countries.
The oystervpn apps cover Windows and マック desktop apps, plus an iOS app and Android app.
There are browser extensions too, but no native Linux build.
The draw is lifetime access for one payment.
This clip shows the oystervpn app and how the connection screen behaves.
オイスターVPN
An Ireland-based vpn service with AES-256 encryption and dedicated streaming servers. Torrenting is allowed on every server. Every OysterVPN subscription carries a 30 day money back guarantee.
Oyster VPNの料金
OysterVPN offers one feature set. You only pick the term length.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月＋2ヶ月無料 | 月額5.99ドル | サービスを試してみます |
| 1年 | 月額29.99ドル | An annual commitment |
| 生涯アクセス | 月額59.99ドル | One payment, no renewals |
Pricing verified September 2026.
無料トライアル: None. OysterVPN does not offer a free trial or a free vpn tier.
返金保証: 30 days on every plan, so you can test the service risk free.
📌 注記： When you purchase OysterVPN, only major credit cards and PayPal work. There is no cryptocurrency option, which matters if anonymous billing is part of your threat model.
⚠️ 警告： Our figures follow the CSV pricing. Other sources list $9.99 monthly with 3 free months, $2.50 per month yearly, and lifetime access at $49.99. Confirm the number at checkout.
Oyster VPNの主な利点
Where OysterVPN earns its place:
- 生涯アクセス: One payment and the account never expires. No renewal date to track.
- ストリーミングのブロック解除： Dedicated streaming servers reach popular streaming services like Netflix, Max, ESPN+, and BBC iPlayer. Hulu and Disney+ are hit or miss.
- Torrenting Anywhere: P2P file sharing is allowed on all of its servers, with solid security features behind it.
- アイルランドの管轄権： GDPR applies and the country sits outside the main intelligence alliances. Good baseline online security for a small provider.
- 広告とマルウェアのブロック： A built-in blocker trims ads and bad domains, no extra software needed.
- シンプルなアプリ： A user friendly interface on desktop and mobile. You can install OysterVPN in minutes.
- Five Devices: OysterVPN supports multiple devices, up to five simultaneous connections per account.
私たちのチームが気づいたこと

機能比較
Both tools do the same basic job. They route your connection through a remote vpn server and hide your ip addresses.
The gap shows up in proof, scale, and speed. Twelve areas decide the winner.
| 特徴 | プライベートインターネットアクセス | オイスターVPN |
|---|---|---|
| 開始価格 | 月額2.03ドル | 月額5.99ドル |
| 無料プラン | ❌ | ❌ |
| 監査済みログなしポリシー | ✅ デロイト | ❌ なし |

| 最適な用途 | 予算内でプライバシーを保護 | One-off payment and streaming |
1. No Logs Policy and Audits
プライベートインターネットアクセス: The privacy policy rules out browsing history, user IPs, connection timestamps, bandwidth logs, and dns queries. Deloitte has confirmed that strict no logs policy through more than one audit. Quarterly transparency reports list the legal requests received.
オイスターVPN: OysterVPN also claims a strict no logs policy and says it collects no user data. The difference is verification. OysterVPN has not undergone a third-party independent audit of its privacy policies or security measures, so the zero logging policy rests on trust alone.
⚠️ 警告： An unaudited logs policy is not proof of wrongdoing. It only means nobody outside the company has checked. If you need an audited no logs policy, that narrows your choice to one.
2. Encryption Level
プライベートインターネットアクセス: AES 256-bit encryption runs over the オープンVPN protocol, or ChaCha20 on WireGuard. The encryption level is adjustable in settings, which is unusual. PIA supports multi-hop too, routing traffic through two vpn servers.
オイスターVPN: OysterVPN uses AES-256 encryption on every plan. There is no multi-hop and no adjustable cipher. For ordinary browsing that is enough, and it matches the advanced security features most vpn services ship.
3. VPNプロトコル
プライベートインターネットアクセス: OpenVPN and WireGuard are both built in, switchable inside the app. Test both: PIA’s performance on Windows using the OpenVPN protocol beats WireGuard in several setups.
オイスターVPN: OysterVPN lets you choose from multiple secure vpn protocols, including WireGuard, OpenVPN, and IKEv2. Coverage is uneven though. OysterVPN does not support the WireGuard protocol in every app, so some platforms fall back to OpenVPN.
4. キルスイッチ
プライベートインターネットアクセス: Two kill switches ship on Windows and macOS, a regular one and an advanced one. Both cut internet traffic the moment the vpn connection drops, so your data private stays that way.
オイスターVPN: One internet kill switch blocks internet access if the vpn connection drops, stopping accidental data leaks. That is a crucial feature on flaky mobile networks.
5. DNS and Leak Protection
プライベートインターネットアクセス: PIA runs its own dns servers, so your dns requests never reach your ISP. A built-in tool checks for dns leaks any time, and confirms your actual ip address is hidden.
オイスターVPN: OysterVPN prevents IP, DNS, and WebRTC leaks. Its dns leak protection held up in published leak tests, and ip leak protection hides your real location. There is no in-app tester, so use an external site.
6. Breach Monitoring
プライベートインターネットアクセス: Identity Guard watches your email addresses and warns you when one appears in a breach. An email leak test shows whether your address is exposed outside the vpn tunnel.
オイスターVPN: No breach monitoring. OysterVPN features stop at the vpn connection and the ad blocker. If you want identity tools bundled in, this is not the vpn app for it.
7. 分割トンネル工法
プライベートインターネットアクセス: The split tunneling feature excludes specific apps and even specific IP addresses from the vpn connection. Keep browser traffic protected and let a game bypass it at full connection speed. オートメーション rules connect or disconnect based on the network you join.
オイスターVPN: Split tunneling exists, but only on the Windows and Android apps. iOS and Mac users miss out. You pick which apps use the tunnel, with no per-IP control.
8. Device Limits and Coverage
プライベートインターネットアクセス: Unlimited connections on one account. Router support extends that to consoles and anything that cannot run vpn apps. That is how PIA covers all your devices, including streaming devices.
オイスターVPN: Five simultaneous connections, and no app for smart TVs or gaming consoles. For one person with a phone, laptop, and tablet that is fine. For a family it runs out fast.
9. Gaming and Dedicated IP
プライベートインターネットアクセス: A dedicated ip address is available as an add-on. It cuts CAPTCHAs, helps with incoming connections, and pairs with port forwarding. Handy for online gaming and for unblocking streaming content that flags shared IPs.
オイスターVPN: No dedicated IP, but ddos protection runs on all of oystervpn’s servers. That absorbs flood attacks before they reach you, which competitive players will value more than a static address.
10. Ad Blocking and Extras
プライベートインターネットアクセス: MACE blocks ads and trackers at the DNS level. Paid tiers add antivirus scanning on top, so one subscription handles more than the vpn tunnel.
オイスターVPN: A built-in ad and malware blocker runs across desktop and mobile apps. It does the basics well and saves you installing separate browser extensions.
11. Speed, Streaming and Torrenting
プライベートインターネットアクセス: Average download speed loss is about 49%, and upload speed loss usually runs higher. Speed tests swing a lot by server location and protocol. Streaming optimized servers reach Netflix and Disney Plus, though Amazon Prime Video and BBC iPlayer are less consistent. It is still a top tier vpn for privacy, just not for raw throughput.
オイスターVPN: OysterVPN’s speeds are decent on a nearby server and fall away on long-distance hops, dropping by an average of 55%. A speed test to the fastest server nearby looks fine. Reaching geo restricted content across an ocean is where streaming services start buffering. Torrenting is allowed everywhere on P2P-ready servers.
⚠️ 警告： Neither tool is built for bandwidth-heavy work. PIA is not ideal for bandwidth-intensive applications, and OysterVPN is not suited to streaming 4K content over distant servers.
12. 価格設定とコスト
Here are both pricing plans side by side.
| プランの種類 | プライベートインターネットアクセス | オイスターVPN |
|---|---|---|
| 無料プラン | ❌ | ❌ |
| 毎月 | 月額11.99ドル | 月額5.99ドル |
| Mid term | $7.50/month (6 Months) | 月額29.99ドル（1年間契約） |
| Long term | 月額2.03ドル（2年4ヶ月） | $59.99/month (Lifetime Access) |
| Refund window | 30日間 | 30日間 |
プライベートインターネットアクセス: The long plan is the whole argument. At $2.03 a month you get unlimited devices, unlimited bandwidth, and an audited record. That makes it an affordable vpn without the usual trade-offs.
オイスターVPN: The one-off lifetime plan is the draw. Keep the account four or five years and the maths works. Just remember a lifetime plan is only as good as the company behind it.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| The lowest running cost | プライベートインターネットアクセス | $2.03 vs $5.99 entry price |
| One payment, no renewals | オイスターVPN | Lifetime access plan |
| Proof of privacy claims | プライベートインターネットアクセス | Deloitte audits, open code |
| To cover a whole household | プライベートインターネットアクセス | 無制限の接続 |
| どのサーバーでもトレントを利用できます | オイスターVPN | P2P allowed network-wide |
| Live help when stuck | プライベートインターネットアクセス | Real chat support |
💰 あなたの予算
PIA is the cheap vpn here on any yearly view. OysterVPN only wins if lifetime access has years to pay off.
🔌お使いのデバイス
Count what you own. Five slots vanish once a partner, a tablet, and a TV box join in.
📝 Your Privacy Standard
Some vpn users want claims checked by outsiders. Others accept a policy at face value. That 質問 settles most of this comparison.
🎓 あなたの経験レベル
OysterVPN is the simpler start, with a clean desktop app and few settings. PIA rewards power users with protocol switching and オートメーション.
🆓 無料トライアルとデモ
Neither offers a free tier. Both give 30 days to ask for your money back, so run your own speed test 早い.
🛟 サポートオプション
PIA has live chat and a big help centre. OysterVPN’s customer support is email only, and replies can be slow.

私たちのレビューで取り上げられなかったこと
This comparison looked at individual users and small households. We did not test 仕事 licensing, router firmware, or reliability in restrictive countries. OysterVPN is reported to struggle in places like China, and we did not verify that. Virtual servers versus owned hardware is another gap, since neither provider publishes a full breakdown.

🏆 WINNER: PRIVATE INTERNET ACCESS
プライベート・インターネット・アクセスは、8部門中5部門で受賞した。
最適な用途: households with many devices, privacy-first buyers, and anyone who wants a quality vpn under $3 a month.
These are not evenly matched products. PIA is a large, audited operation that happens to be cheap. OysterVPN is a small provider with one clever pricing idea.
OysterVPN is still a decent vpn for one person who streams, torrents, and mostly connects to a nearby server. The lifetime plan is a real advantage over several years.
But if you want proof rather than promises, Private Internet Access makes the stronger case.

よくある質問
プライベートインターネットアクセスは安全ですか？
Yes. It uses AES 256-bit encryption, runs open-source apps, and Deloitte has verified the no-logs claim more than once. A kill switch protects you if the tunnel fails.
Oyster VPNは信頼できるVPNですか？
Yes. It is run by an Irish company, uses AES-256, and blocks IP, DNS, and WebRTC leaks. The catch is that no outside auditor has checked those claims.
PIA VPNの料金はいくらですか？
Three plans: $2.03 a month on the 2 Years + 4 Months term, $7.50 on six months, and $11.99 monthly. Renewal prices do not go up.
Oyster VPNは良いサービスですか？
For basic browsing and streaming on a close server, yes. It handles Netflix and Max well. Long-distance speeds and the missing audit hold it back.
PIAよりも優れたVPNはどれですか？
NordVPN and ExpressVPN beat it on speed and streaming consistency. Neither matches its price or unlimited device policy, so “better” depends on what you value.
