3 Best VPNs for Synology NAS in 2023 (Free & Paid)

If you use a Synology NAS device, adding an extra layer of security with a VPN is highly recommended when accessing your files remotely. VPNs encrypt your connection, making it impossible for hackers to spy on your activities or steal data in transit.

In this guide, we‘ve researched and reviewed the top 3 VPN options for use with Synology NAS to help you choose the best one for your needs and budget in 2023.

Why Should You Use a VPN with Your Synology NAS?

Here are some key reasons experts recommend using a reliable VPN in tandem with your Synology NAS:

  • Enhanced Security – VPNs create an encrypted tunnel for all network traffic between your device and the VPN server. This secures your NAS against eavesdropping and man-in-the-middle attacks when transferring files.
  • Anonymity – Your real IP address is hidden by the VPN, providing complete privacy online.
  • Bypass Geo-restrictions – Connecting via a VPN server in another location lets you easily access region-locked streaming content like Netflix libraries abroad.
  • Faster Speeds – Establishing a connection to the nearest VPN server can provide faster speeds vs. your regular ISP for activities like large downloads from your NAS. According to a 2021 survey by VPNGurus, over 80% of remote NAS users experienced speed gains with a VPN.
  • Public Wi-Fi Protection – Using free public hotspots to remotely access your NAS can be very risky without a VPN to encrypt the connection.
  • VPN Protocol Compatibility – Synology NAS devices support OpenVPN, IKEv2 and other protocols to make connecting to a VPN simple.

VPN Protocols Supported by Synology NAS Devices

Synology NAS systems like the DS220+, DS720+, DS1019+ etc. are compatible with most major VPN protocols like:

OpenVPN – This open-source protocol is preferred for NAS devices due to its speed, reliability and security through 256-bit AES encryption. Most VPN providers like NordVPN support OpenVPN.

IKEv2/IPSec – IKEv2 is fast and secure, using strong 256-bit AES encryption. VPN providers like Surfshark support IKEv2.

L2TP/IPSec – A default protocol that comes built-in on Synology devices. Offers decent speeds but weaker security than OpenVPN.

PPTP – An older protocol avoided today due to security vulnerabilities. But supported as a legacy protocol on Synology NAS for backward compatibility.

Experts recommend using OpenVPN where possible as it provides the best balance of security, speed and reliability for VPN connections to your Synology device. However, IKEv2 and L2TP are also good alternates if you have any compatibility issues.

Paid vs. Free VPN for Synology NAS – Which Should You Choose?

Opting for a free VPN may seem tempting, but paid VPN services have significant advantages for use with your Synology NAS:

  • Better speeds – Free VPNs often throttle speeds whereas paid options like NordVPN have speedy servers optimized for activities like 4K streaming and large file downloads.
  • More server locations – Paid VPNs have thousands of servers spanning 60+ countries compared to just a handful of locations with free ones. This allows you to bypass geoblocking anywhere.
  • Stronger security – Free VPNs have weaker encryption standards, lack a kill switch feature, and can have security flaws. Paid services like Surfshark use 2048-bit encryption and all the latest security tools.
  • No data caps – Free VPNs impose annoying data caps as low as 2-5GB/month. With paid services you get unlimited bandwidth.
  • Better reliability – Prominent paid VPNs offer 99.9% uptime guarantees versus frequent connection drops with free ones.
  • No logging – Many free VPN providers log user data and online activities which paid options like NordVPN never track.

The one advantage of free VPNs is letting you access basic functionality without spending money. Atlas VPN stands out for offering unlimited data even on their free plan. But for worry-free security and speed for your NAS, a premium VPN like NordVPN is well worth the investment.

Factors to Consider When Choosing a Synology NAS VPN

Here are some key criteria to evaluate when picking the right VPN service for your Synology device:

Protocols Supported – OpenVPN support is strongly recommended. L2TP and IKEv2 also provide good connectivity.

Speeds – Look for consistent 40-50 Mbps+ download speeds, minimum for HD streaming and quick NAS access. NordVPN excels here.

Server Locations – Widespread server coverage allows you to bypass geo-restrictions anywhere and enjoy stable uptime.

Synology App – User-friendly custom apps from the VPN provider simplify connecting your NAS device.

Simultaneous Connections – If you have 5+ devices accessing your NAS remotely, unlimited connections provided by Atlas VPN and Surfshark are beneficial versus just 6 with NordVPN.

Security Features – AES-256 bit encryption, secure protocols, DNS leak protection, kill switch and zero-logging policy are vital.

Pricing – Aim for plans under $10/month if paying yearly. Atlas VPN and Surfshark offer the most affordable rates.

Free Trial – Test out the VPN‘s speeds and reliability before committing to check it meets your needs. NordVPN and Surfshark have free trial options.

Conclusion – Boost Your Synology NAS Security with a VPN

Adding an extra layer of privacy and security with a VPN is strongly recommended if you access and manage your Synology NAS remotely. Beyond security, VPNs also unlock geo-restricted content, provide anonymity online, and boost speeds.
