The best Synology VPN depends on whether you want a DSM-wide OpenVPN client, a Docker-only tunnel, private remote access, or provider-side port forwarding for a specific application.
Surfshark is the best broad Synology commercial-VPN fit for most owners
Surfshark wins the general recommendation because it has current Synology-specific OpenVPN guidance, works well with Docker/Gluetun for selective routing, and supports unlimited simultaneous devices. NordVPN is an excellent DSM OpenVPN alternative. Proton VPN moves to the top when provider-side port forwarding is a hard requirement. For reaching your Synology remotely, use Tailscale or QuickConnect rather than buying a commercial VPN for the wrong job.

How we rank a VPN specifically for Synology DSM
A generic VPN ranking is not enough for Synology because DSM is an appliance operating system with its own supported network interfaces and package lifecycle. We give extra weight to providers that document Synology setup, expose standard protocols, work cleanly in Docker when selective routing is preferable, and are honest about port-forwarding limits. We also consider how likely a host-wide tunnel is to interfere with QuickConnect, Hyper Backup, package updates and Plex remote access.
The safest recommendation is the provider whose features match the layer you actually plan to use. If DSM itself needs an outbound tunnel, official OpenVPN guidance is valuable. If only qBittorrent needs privacy, Docker plus Gluetun is more precise. If remote access is the goal, Tailscale or QuickConnect belongs in the conversation instead of a commercial exit VPN.
Surfshark is our best overall Synology VPN
Surfshark publishes a dedicated OpenVPN setup path for Synology NAS, including the use of manual service credentials rather than the normal account email and password. That matters because it reduces guesswork inside DSM’s VPN client. Surfshark also supports standard manual WireGuard for Linux-oriented deployments, so the same subscription can fit a Docker/Gluetun path when you do not want to change the whole NAS default route.
The service is especially attractive in a household with many devices because Surfshark permits unlimited simultaneous connections. The limitation is equally important: Surfshark does not provide conventional VPN-side port forwarding. If your Synology downloader depends on accepting an inbound port through the VPN provider, choose a provider that explicitly supports that workflow rather than trying to manufacture the feature with DSM port mappings.
NordVPN is the strongest DSM OpenVPN alternative
NordVPN also publishes Synology NAS setup instructions using OpenVPN profiles, making it a comfortable choice for owners who already use NordVPN across other devices. The documented path fits DSM’s supported VPN client model and avoids unsupported modifications to the underlying operating system. If the goal is simply to send selected or host-wide outbound traffic through NordVPN, that official documentation is a meaningful advantage.
NordVPN does not offer provider-side port forwarding, so it has the same major P2P caveat as Surfshark. NordLynx is WireGuard-based, but that does not mean every NAS can import it exactly like a generic WireGuard configuration from another provider. For Docker-heavy Synology users, check the current container/provider integration rather than assuming protocol branding alone guarantees portability.
Proton VPN is the better Synology choice when port forwarding matters
Proton VPN earns a different kind of recommendation. It supports standard WireGuard configurations and documents port-forwarding workflows on paid plans. For a downloader running in Docker, that can be more valuable than having a polished DSM-wide client tutorial. The container can establish the provider tunnel, retrieve or maintain the forwarded port, and pass that value to the application while DSM itself remains on the normal route.
This architecture is especially good when the NAS runs Plex, Photos, backups and other services that should not inherit the provider’s public IP. The forwarded port can be dynamic depending on the workflow, so automate or document how the application is updated after a reconnect. Do not confuse the provider-side port with a Docker host port or a router forwarding rule; they operate at different boundaries.
PIA and Mullvad fit advanced Synology Docker stacks
Private Internet Access remains useful for technically comfortable users because it supports OpenVPN, WireGuard and port-forwarding features in supported regions. In a Synology Docker stack, PIA can work well when the user is willing to manage the container or scripts needed to establish the tunnel and keep the application synchronized with the provider’s port behavior. It is less compelling if the only requirement is a simple documented DSM click-through setup.
Mullvad is nearly the opposite: it is attractive for straightforward WireGuard configuration and privacy-focused container routing, but it no longer offers port forwarding. A Synology user who wants a clean Gluetun/WireGuard exit and does not care about inbound peer reachability may prefer that simplicity. Both providers make more sense when chosen for their specific features rather than as generic “top five” filler.
Use DSM’s built-in VPN client only when host-wide routing is really desirable
DSM can connect to supported VPN servers, including OpenVPN providers, but making that tunnel the default route changes the behavior of the entire NAS. Package downloads, external backups, webhooks, Plex remote access and vendor services may now leave through the provider instead of the ISP. That can be exactly what you want on a dedicated privacy appliance and completely wrong on a mixed family NAS.
Before enabling a default gateway through the VPN, list the services that depend on inbound reachability or a stable home public IP. Test local SMB and DSM access, then test QuickConnect, Hyper Backup destinations, notifications and Plex from an external network. If too many exceptions are required, move the commercial VPN down to the Docker layer rather than fighting DSM’s host routing.
Docker and Gluetun are usually the cleanest route for one privacy-sensitive app
Synology models that support Container Manager/Docker can isolate the VPN requirement to the application that actually needs it. Gluetun can own the Surfshark, Proton, PIA or Mullvad tunnel while qBittorrent, an indexer or another app shares the gateway network. DSM, SMB, Photos and Plex remain on normal interfaces. This is easier to reason about than a whole-NAS VPN because the blast radius is deliberately small.
Publish the application Web UI port on the VPN gateway when the app shares its network namespace, and explicitly allow the trusted LAN subnet through the gateway firewall. Then test the application’s public IP and DNS from inside the protected container. Stop Gluetun and confirm the application loses internet access instead of silently falling back to the ordinary WAN.
Keep Plex outside the commercial VPN unless you have a specific reason
A Synology often doubles as a Plex server, and this is where host-wide provider tunnels create the most visible problems. Plex remote access expects predictable reachability from the public internet. A commercial VPN can change the source address and default route, while providers such as Surfshark and NordVPN do not give you an inbound forwarded port to restore the same topology. The result can be a Plex server that works locally but becomes unreliable remotely.
The cleaner design is to leave Plex on the normal WAN or use Tailscale for private playback on approved devices, while the downloader uses a separate VPN path. That separation is not a workaround; it is good network architecture. Media serving and outbound privacy are different jobs and should not be forced through one route simply because they run on the same NAS.
Use Tailscale or QuickConnect for remote Synology administration
Commercial VPN marketing often makes users think “VPN equals secure remote access,” but the direction matters. Surfshark or NordVPN on DSM connects the NAS outward. Tailscale connects your authorized devices into a private overlay, and QuickConnect provides Synology’s vendor-managed remote path. Those are the tools to consider when you want to open DSM or reach files from a laptop away from home.
Cloudzat already covers Synology remote access and Tailscale versus QuickConnect separately because those decisions deserve their own security model. Keep SMB and DSM administration off the public internet. If both Tailscale and a commercial VPN are active, preserve Tailscale routes so the provider default route cannot hijack remote-management traffic.
NAS CPU power determines VPN speed more than your 2.5GbE LAN label
Encryption and protocol processing happen on the NAS CPU or container host. An entry-level ARM Synology can saturate a modest internet connection yet fall far short of multi-gigabit VPN throughput. An Intel or AMD model with more CPU headroom can handle faster WireGuard/OpenVPN sessions, but the exact result depends on protocol, cipher, kernel support and workload. Your local 2.5GbE or 10GbE link can remain fast even if the commercial VPN is much slower.
Benchmark local storage separately from internet-VPN performance. If local transfers are fast but the VPN is slow, do not blame the drives. Test WireGuard where supported, compare OpenVPN if that is the official DSM path, and watch CPU load during a large outbound transfer. Choose the NAS for the whole workload, not for a theoretical VPN speed number alone.
Dedicated IP does not replace the missing inbound features
Some VPN providers sell dedicated or static-style exit IP options. A consistent outbound IP can be useful for allowlists, remote services that dislike shared VPN addresses, or reducing CAPTCHAs. It does not automatically mean the provider accepts arbitrary inbound connections or supports port forwarding. Those are separate features.
For a Synology, decide what problem you are solving. If a cloud backup partner needs to allowlist one outbound address, a dedicated IP can help. If a qBittorrent container needs an inbound listening port through the provider, verify port-forwarding support specifically. If you need DSM remote access, use Tailscale, QuickConnect or a self-managed VPN server instead. Precise feature language prevents expensive misconfiguration.
Our Synology VPN picks by workload
For a mixed Synology household where you want an easy commercial-VPN option across DSM, containers and many personal devices, Surfshark is the best overall fit. For users who already prefer NordVPN and want a documented DSM OpenVPN path, NordVPN is a strong alternative. For qBittorrent and other P2P workloads where provider-side port forwarding matters, Proton VPN is the first provider to evaluate, with PIA as another advanced option. Mullvad remains attractive for simple WireGuard-oriented container routing without port forwarding.
For remote Synology access, none of those commercial rankings should override the architecture: use Tailscale or QuickConnect. Keep Plex and storage administration on routes designed for reachability, and send only privacy-sensitive egress through the commercial provider. That combination gives better reliability than trying to make one subscription solve every networking problem.
