最佳VPN优惠活动：ExpressVPN、ProtonVPN、Surfshark等品牌最高可享77折优惠
顶级VPN服务商正在大幅下调长期套餐价格——来看看哪里能省得最多。

若使用得当，虚拟专用网络（VPN）能为您省下不少开支。通过更改虚拟定位，您只需一个流媒体账号就能观看在本国需订阅三四个平台才能收看的节目。您还能在全球范围内搜寻仅限特定区域显示的折扣优惠。当然，从无孔不入的广告和追踪器中夺回网络自主权带来的愉悦更是无价的。

各家VPN服务商正竞相争夺用户资源，因此经常为愿意一次性订阅一至两年的用户提供大幅折扣。下文列出的优惠多属此类。在浏览清单前，请确认您能接受较长的合约期限。

超值VPN优惠推荐
这款瑞士VPN是Engadget当前首推的优选服务，具体理由已在Proton VPN完整评测中说明。其在各平台均呈现直观易用的界面，特别适合多设备家庭用户。即使长距离传输也能保持浏览高速与低延迟。对于需要完全匿名的用户，Proton VPN是业内唯一实现全盘加密的服务商，这意味着它能管理所有流量却不让Proton自身窥见任何数据。虽然相关优惠入口隐蔽，但可享原已亲民价格基础上66%的折扣——这是笔者追踪该品牌以来的史低价格。请尽快入手，优惠持续时间无法保证。

NordVPN——两年订阅套餐83.43美元附赠三个月（77折）：NordVPN精准把握了VPN的核心要素。速度快、零数据泄漏且虚拟定位功能出色。笔者在评测中发现其连接始终迅速，并配备可即时获取在线帮助的支持页面。虽然对其关闭Meshnet功能感到遗憾，但NordVPN仍保留诸多实用功能（如直连Tor网络的服务器）。本优惠享两年方案77折，额外赠送三个月——且无截止日期，您可从容比价。

ExpressVPN——基础版两年订阅97.72美元附赠四个月（73折）：作为顶级VPN服务商之一，其应用与网站在全平台均提供零门槛操作体验，特别适合新手用户。实测数据显示，下载速度损耗低于7%，15次虚拟定位测试中成功14次。总而言之，这是款全能型优质服务，唯一缺点是定价偏高——正因如此，其难得推出的优惠才令人振奋。本次28个月服务套餐可省73%费用，是近期罕见的低价位，但与NordVPN一样未设截止期限。

Surfshark Starter——两年订阅53.73美元附赠三个月（87折）：虽属"基础版"，但包含完整VPN功能；Surfshark One的所有附加服务均需额外付费。此订阅方案提供当前VPN领域最具突破性的功能：其服务器网络连接密度高于多数竞品，可通过持续更换IP地址避免被侦测——甚至支持自选入口与出口节点构建双跳连接。这些功能对下载速度的影响微乎其微。本次全年优惠可享27个月服务87折。

Surfshark One——两年订阅67.23美元附赠三个月（86折）：单靠VPN并不足以全面保护数据安全。此套餐新增多款安全应用：Surfshark防病毒软件（扫描设备及下载文件中的恶意软件）、Surfshark警报系统（在敏感信息出现在数据泄露事件时即时通知）、Surfshark搜索引擎（无广告无活动追踪的私密搜索）。此常驻优惠可享所有功能86折。若升级至Surfshark One+还会增加Incogni数据清除服务，但溢价过高，笔者认为性价比不足。

CyberGhost——两年订阅56.94美元附赠两个月（83折）：该品牌拥有VPN界顶尖的自动化功能。通过智能规则系统，可自定义应用对不同Wi-Fi网络的响应机制，甚至为指定名称的网络设置例外规则。通常可设置为自动连接、断开连接或发送询问提示。其另一王牌是流媒体专用服务器——虽未公开优化细节，但实测在流媒体平台能获得更佳画质与更稳定的解锁表现。现享26个月服务83折优惠。

Private Internet Access（PIA）——三年订阅79美元附赠三个月（83折）：需通过段落前链接获取优惠券，但这是笔者推荐VPN中的当前最低价。39个月服务折合月费仅2美元出头——相当于月租价格83折。虽价格低廉，PIA却毫不显得廉价：配备专属DNS服务器、内置广告拦截器及媲美CyberGhost的自动化功能。但需注意连接时网速可能波动。

如何甄选优质VPN优惠
如开篇所述，几乎所有VPN服务商全年都在大力促销长期套餐。唯一例外是Mullvad，堪称VPN界的"开市客热狗"（明确说这是褒义）。当折扣成为常态时，消费者往往难以辨别真正实惠的时机。最佳策略是关注季节性活动、学生优惠或独家促销（例如Proton VPN为Engadget读者提供的优惠券）。

VPN商常用策略是在首购套餐中增加额外使用时长来拉低月均成本。但续费时通常无法再次获得赠时，甚至可能无法按原周期续约（例如两年套餐到期后仅能续订一年）。若计划长期使用，请仔细阅读条款中首期过后续费价格的细则，确保符合您的预算规划。

The best VPN deals: Get up to 77 percent off ExpressVPN, ProtonVPN, Surfshark and others
Top VPNs are sharply discounting long-term plans — see where you can save the most.
A virtual private network (VPN) can save you a lot of money if you use it right. By changing your virtual location, you can use one streaming service to see shows that might be scattered between three or four in your home country. You can also trawl the world for discounts that only show up in a few select regions. And of course, you can't put a price on the joy of taking back your online business from intrusive ads and trackers.
VPN providers are all competing to boost their subscriber counts, so they frequently offer massive discounts to anyone willing to sign up for one or two years at a time. Most of the deals below fit into that category. Before you jump into the list, make sure you're OK with a longer-term commitment.
Best VPN deals
This Swiss VPN is Engadget's top VPN of choice right now, for reasons I've laid out in a full Proton VPN review. It looks and feels good to use on every platform, which makes it fantastic for multiple-device households. It keeps your browsing speeds fast and latencies low, even over long distances. For those who need a VPN to stay anonymous, Proton VPN is the only service implementing full-disk encryption, which means it can manage all your traffic without any of it being visible to Proton itself. The linked deal is hard to find, but it's a 66 percent discount on an already affordable service — the cheapest Proton VPN has sold for since I started tracking it. Grab it soon, since I can't be sure how long it will last.
NordVPN — $83.43 for a two-year subscription with three months free (77 percent off): NordVPN gets the most important parts of a VPN right. It's fast, it doesn't leak any of your data and it's great at changing your virtual location. I noted in my NordVPN review that it always connects quickly and includes a support page that makes it easy to get live help. Although I'm sad to see it shutting down Meshnet, NordVPN still includes a lot of cool features, like servers that instantly connect you to Tor. This deal gives you 77 percent off the two-year plan, which also comes with three extra months — but there's no expiration date, so you have a little time for comparison shopping.
ExpressVPN — $97.72 for a two-year Basic subscription with four months free (73 percent off): This is one of the best VPNs, especially for new users, who will find its apps and website headache-free on all platforms. In tests for my ExpressVPN review, it dropped my download speeds by less than 7 percent and successfully changed my virtual location 14 out of 15 times. In short, it's an all-around excellent service that only suffers from being a little overpriced — which is why I'm so excited whenever I find it offering a decent deal. This deal, which gets you 28 months of ExpressVPN service, represents a 73 percent savings. It's the lowest I've seen ExpressVPN go in some time, though like NordVPN, it's not on a ticking clock.
Surfshark Starter — $53.73 for a two-year subscription with three months free (87 percent off): This is the "basic" level of Surfshark, but it includes the entire VPN; everything on Surfshark One is an extra perk. With this subscription, you'll get some of the most envelope-pushing features in the VPN world right now. Surfshark has a more closely connected server network than most VPNs, so it can rotate your IP constantly to help you evade detection — it even lets you choose your own entry and exit nodes for a double-hop connection. That all comes with a near-invisible impact on download speeds. With this year-round deal, you can save 87 percent on 27 months of Surfshark.
Surfshark One — $67.23 for a two-year subscription with three months free (86 percent off): A VPN is great, but it's not enough to protect your data all on its own. Surfshark One adds several apps that boost your security beyond just VPN service, including Surfshark Antivirus (scans devices and downloads for malware), Surfshark Alert (alerts you whenever your sensitive information shows up in a data breach) and Surfshark Search (a private search engine with no ads or activity tracking). This evergreen deal gives you 87 percent off all those features. If you bump up to Surfshark One+, you'll also get data removal through Incogni, but the price jumps enough that it's not quite worthwhile in my eyes.
CyberGhost — $56.94 for a two-year subscription with two months free (83 percent off): CyberGhost has some of the best automation you'll see on any VPN. With its Smart Rules system, you can determine how its apps respond to different types of Wi-Fi networks, with exceptions for specific networks you know by name. Typically, you can set it to auto-connect, disconnect or send you a message asking what to do. CyberGhost's other best feature is its streaming servers — while it's not totally clear what it does to optimize them, I've found both better video quality and more consistent unblocking when I use them on streaming sites. Currently, you can get 26 months of CyberGhost for 83 percent off the usual price.
Private Internet Access — $79 for a three-year subscription with three months free (83 percent off): It's a bit hard to find (the link at the start of this paragraph includes the coupon), but Private Internet Access (PIA) is giving out the best available price right now on a VPN I'd recommend using. With this deal, you can get 39 months of PIA for a little bit over $2 per month — an 83 percent discount on its monthly price. Despite being so cheap, PIA almost never comes off as a budget VPN, coming with its own DNS servers, a built-in ad blocker and automation powers to rival CyberGhost. However, internet speeds can fluctuate while you're connected.
What makes a good VPN deal
Like I said in the intro, practically every VPN heavily discounts its long-term subscriptions the whole year round. The only noteworthy exception is Mullvad, the Costco hot dog of VPNs (that's a compliment, to be clear). When there's constantly a huge discount going on, it can be hard to tell when you're actually getting a good deal. The best way to squeeze out more savings is to look for seasonal deals, student discounts or exclusive sales like Proton VPN's coupon for Engadget readers.
One trick VPNs often use is to add extra months onto an introductory deal, pushing the average monthly price even lower. When it comes time to renew, you usually can't get these extra months again. You often can't even renew for the same basic period of time — for example, you may only be able to renew a two-year subscription for one year. If you're planning to hold onto a VPN indefinitely, check the fine print to see how much it will cost per month after the first renewal, and ensure that fits into your budget.
