| 開始価格 | 月額0.83ドル | 年間59.99ドル(バンドル価格) |
| 無料プラン | ❌ | ❌ (200MB/day with a security suite) |

| 最適な用途 | Budget standalone VPN | Bitdefenderアンチウイルスユーザー |
1. サーバーネットワークと場所
最速VPN: It runs a small server network of around 800 servers in 49 countries. That still covers the main server locations. With so few servers, peak hours can feel crowded. Check whether a location uses virtual servers if physical location matters to you.
ビットディフェンダーVPN: It lists over 4,000 servers in 54 countries. The server list includes a favorites system for quick picks. You can also let the app choose a VPN server for you.

2. Speed & Protocols
最速VPN: FastestVPN claims top speed in its name, but tests tell another story. Third-party speed tests hit about 730 Mbps on a nearby server using the WireGuard protocol. Download speeds still dropped about 45% on average, and up to 55% on long-distance servers.
ビットディフェンダーVPN: It uses Catapult Hydra, plus WireGuard and オープンVPN. Connection times are short, often just a few seconds. Speeds trail specialist providers like ノードVPN and ExpressVPN. Ping times rise on servers in 日本 and Australia.
⚠️ 警告: Slow speeds hit both tools on far servers. One test of FastestVPN showed latency rising 33%, with weak upload results. Pick a nearby server location and OpenVPNを使用する TCP only when you need extra reliability.
3. 暗号化とセキュリティ
最速VPN: Every connection uses AES-256 encryption. A built-in NAT firewall blocks unwanted incoming traffic. It also includes malware protection.

ビットディフェンダーVPN: It also uses AES-256 encryption. It adds public Wi-Fi protection and filters harmful websites. Its tie to Bitdefender’s antivirus software helps against online threats.

4. キルスイッチと漏電防止
最速VPN: Its kill switch cuts your internet if the VPN drops. Some reviews 質問 how well it works. DNS leak protection sends DNS requests through its own network.
ビットディフェンダーVPN: Its automatic kill switch stops traffic if the VPN connection fails. Some reports mention inconsistent leak protection. Run your own DNS leak tests after setup.
⚠️ 警告: DNS and IP leaks have been reported on FastestVPN’s Windows app. Check for data leaks on any Windows computer before you rely on it.
5. プライバシーとログ記録
最速VPN: It follows a strict no-logs rule with no activity logs or connection timestamps. Your online activities aren’t recorded, and Altius IT audited that claim. Your DNS queries also stay on FastestVPN’s servers.

ビットディフェンダーVPN: It doesn’t store traffic logs, IP addresses, or browsing history. It does log some technical data for fraud prevention. That covers user and device IDs, hashed user details, and randomly generated tokens.
A partner handles the network side of providing VPN services. It acts as a data processor and processes data under Bitdefender’s instructions. Reviewers call the privacy policy vague, and it has no separate VPN logging policy.
6. ストリーミングとトレント
最速VPN: It offers streaming servers for popular streaming services, plus a streaming tab. Tests unblocked US, UK, Japan, and Sweden Netflix, plus BBC iPlayer and Hulu. Australian Netflix failed, and some streaming sites loaded slowly. Torrenting works on all FastestVPN servers, but speeds are slow.

ビットディフェンダーVPN: It can reach BBC iPlayer from a UK server. It struggles with US Netflix, Amazon Prime Video, and Disney+. It has no dedicated streaming servers. P2P sharing is allowed, and it helps with some geo restricted content.
7. Split Tunneling & Extra Tools
最速VPN: It offers split tunneling plus smart tunneling. Smart tunneling routes chosen sites through the VPN automatically. Android users get the widest split tunneling support.

FastestVPN also sells port forwarding and dedicated IPs as add-ons. Double VPN, FastestVPN’s ad blocker, and a パスワードマネージャー cost nothing extra. Its browser extensions protect browser traffic only. Most VPN features live in the full apps.
ビットディフェンダーVPN: It lets you choose which apps or domains skip the tunnel. An ad blocker and anti-tracker come built in. It lacks advanced features like double VPN or port forwarding.

8. Devices & Simultaneous Connections
最速VPN: FastestVPN apps run on Windows, Mac, Android, iOS, and Linux. The FastestVPN iOS app and the Mac apps share a simple layout. Manual guides cover routers and Apple TV.

Both services allow 10 simultaneous connections. Only FastestVPN’s apps let you buy extra slots.

ビットディフェンダーVPN: It supports Windows, macOS, Android, and iOS only. There is no Linux, router, or Fire TV Stick support. Its mobile apps are clean, so keep the latest version installed.

9. カスタマーサポート
最速VPN: Customer support runs through 24/7 live chat and email. Replies are fast, but answers can feel generic. Its knowledge base search does not always work well.

ビットディフェンダーVPN: It offers 24/7 live chat, email, and phone support with local numbers. Email replies can take 30 minutes or more. The general support team handles every product, not just the VPN.
