Best Comcast VPN

The best Comcast VPN will prevent the overzealous ISP from throttling your connection and harvesting – and potentially selling – your browsing data. A Virtual Private Network (VPN) routes your internet traffic through an intermediary VPN server, thus hiding your IP address and other personally identifiable information. 

Perhaps more importantly, especially in the case of Comcast, a VPN will encrypt the data so that the ISP can’t see which websites you’re visiting or what you’re doing while you’re there. Without a VPN, Comcast may throttle your connection when you visit certain websites.

Before I get into more detail, here’s a quick summary of the best VPNs for Comcast:

  1. NordVPN: My #1 choice for the best Comcast VPN. Lightning-quick streaming, military-grade security and a huge number of servers worldwide. Comes with a 30-day money-back guarantee.
  2. Surfshark: The best low-cost VPN for Comcast. A user-friendly and secure VPN that plays nicely with Comcast and has no connection limits. 
  3. ExpressVPN: Reputable company with a reliably fast service. Offers high-end security and privacy, and a no-logs policy. 
  4. CyberGhost: Great VPN for first-timers and good-value to boot. Excellent connection speeds and trustworthy security.
  5. PrivateVPN: Fast for streaming and notably committed to privacy and security.
  6. IPVanish: Strong on both security and privacy. Works well with Comcast and has a zero logs policy.
  7. Private Internet Access: Customizable apps and an admirable dedication to privacy. Fast connections and numerous servers, so good for streaming.  
  8. Atlas VPN: Straightforward apps great for accessing a range of streaming services. Unlimited connections available for subscribers.

I have a more extensive section on my methodology later in this article but, for now, here’s a quick list of the criteria I used to choose my list of VPNs.

  • Fast, unthrottled connections for smooth streaming 
  • Servers in countries worldwide (particularly the US)
  • High-end encryption of internet traffic
  • A no-log policy to ensure privacy
  • Around the clock email support and live chat
  • Able to access geo-restricted content

Best Comcast VPNs

1. NordVPN


NordVPN is a fast, secure, and user-friendly VPN that I wouldn’t hesitate to recommend to Comcast customers – particularly those on the receiving end of throttling. It has a massive network of servers worldwide, with almost 2,000 in the US alone. It’s great at accessing a wide variety of streaming sites like Netflix, Amazon Prime Video, and BBC iPlayer – and it also allows unlimited P2P file sharing.

The provider’s apps use the proprietary Nordlynx protocol by default, which is one of the fastest I’ve tried. These are reliable enough to stream video in 4K resolution, or live stream HD video, without any buffering or other issues. 

NordVPN uses military-grade 256-bit AES encryption and operates a zero-logs policy. There’s a kill switch that will halt the flow of internet traffic if the VPN connection drops out and also a pause button if you need to temporarily stop using the VPN.

You can use NordVPN with up to six devices simultaneously, which is plenty for most people. If not, it’s possible to install NordVPN on your router – there are detailed set-up guides available on the NordVPN website. Apps are available for Windows, macOS, iOS, Android, Linux, and Amazon Fire TV.


  • Encrypts all internet traffic and reduces Comcast’s throttling
  • Market-leading security and privacy features
  • Enables access to streaming sites while abroad
  • One of the fastest VPNs around
  • Connect six devices concurrently


  • Automatic server selection isn’t always helpful

BEST COMCAST VPN: A solid option for Comcast customers looking for fast and secure streaming from a variety of sources. Try it risk-free with a 30-day money back guarantee.

2. Surfshark


Surfshark is a good choice for those on a budget, but who still want top class privacy and security. It doesn’t have the massive server network of NordVPN, but that doesn’t stop it providing access to a huge number of region-locked streaming services.

Internet traffic is protected by 256-bit AES encryption, along with a SHA512 authentication hash and 2048-bit DHE-RSA key exchange. It keeps no logs of your online activity, which is important to prevent Comcast snooping on you. There’s also an automatic kill switch to stop unprotected data from leaving your device if the VPN connection drops. 

Surfshark uses the WireGuard protocol to achieve high speeds that are good enough for reliably streaming 4K video and using HD video conferencing. It also allows P2P file sharing on all of its server locations. 

You can simultaneously connect and protect as many devices as you want, which is something of a rarity in the VPN world, and great for large families with older children.

Apps are available for Windows, macOS, iOS, Android, Linux, and Amazon Fire TV. They come with a range of features, including access to double VPN servers, private DNS servers, a no-borders mode and robust leak protection.  


  • Works with Netflix, Amazon Prime Video, and BBC iPlayer
  • Offers a kill switch in all apps
  • Excellent speeds for uninterrupted streaming
  • Guarantees anonymity with a no logs policy
  • Account holders can connect unlimited devices


  • Not quite as many servers as some VPNs

BEST BUDGET OPTION: while retaining all of the features needed to keep you safe and secure. Provides good access to major streaming sites and allows unlimited device connections. Best of all, it comes with a 30-day money-back guarantee.

3. ExpressVPN


ExpressVPN is an established and respected provider, with servers in more than 90 countries. Its proprietary Lightway protocol provides fast connection speeds and rapid switching between mobile and WiFi networks.

Speeds are fast enough for gaming, streaming 4K content, and quickly downloading large files. The apps are easy to use, even for someone new to VPNs.

ExpressVPN provides uncrackable encryption for your internet traffic and won’t keep any logs. All of its apps feature a kill switch, which halts all internet traffic if the VPN unexpectedly disconnects.

Comcast customers can use ExpressVPN to easily access a range of streaming services, including Netflix, Amazon Prime Video, and SkyTV. File sharing is allowed, and not restricted to certain servers. A split tunneling option is available for the Windows, macOS, and Android ExpressVPN apps, which allows you to protect your torrent client with a VPN, but to use other programs without it.  

An ExpressVPN account will let you simultaneously connect up to five devices. If this isn’t enough, you can buy a router with the ExpressVPN firmware already on it, or install it yourself.

Apps are available for Windows, macOS, iOS, Android, Android TV and Nvidia Shield, Linux, and Amazon Fire TV. 


  • Fast speeds across server locations
  • Advanced security on both apps and servers
  • Zero logs policy
  • 24/7 live chat support


  • More expensive than closest competitors
  • Unlabelled streaming servers 

HIGHLY REPUTABLE: offering a combination of speed and security. It’s not the cheapest, but it comes with a 30-day money-back guarantee, so you can try it without committing.

4. CyberGhost


CyberGhost will satisfy Comcast customers who want high speed connections for streaming – it’s one of the fastest VPNs on the market. It also has named gaming servers specifically for anyone wanting to game online.

Torrenting is permitted, and there are plenty of server options for fast and safe downloads. CyberGhost has an app protection feature that allows you to specify if any apps – like a torrent client – should only be allowed to connect to the internet when the VPN is enabled. 

Kill switches are available on both the mobile and desktop apps, stopping the flow of internet traffic if the VPN connection suddenly drops out. This feature cannot be diabled on the desktop app, which could annoy some people. 

Cyberghost doesn’t log its customers’ activity, and provides top-spec 256-bit AES/ChaCha20 encryption. Perfect forward secrecy ensures that even if your encryption key is compromised, it can’t be used to decrypt previous sessions.

A CyberGhost subscription allows you to connect up to seven devices at once, which should be enough for most individuals. Note that there are no apps for routers.


  • Exceptionally quick
  • Allows seven simultaneous connections
  • Unrivaled privacy and security
  • Zero logs policy


  • No apps for routers
  • Previous owners had a poor reputation
  • Local networking not possible

IMPRESSIVE CONNECTION SPEEDS: and secure service that works well with most streaming sites. It comes with a 45-day money-back guarantee.  

5. PrivateVPN


PrivateVPN was started by a group of privacy-focused activists and, as such, it offers a high level for subscribers. It keeps no logs of personally identifiable information and offers adjustable encryption and a variety of protocol options.

Despite having hundreds of servers – rather than the thousands of its competitors – PrivateVPN is one of the fastest VPNs on the market. Comcast customers will easily be able to stream 4K content and play online games with no lag or buffering. 

PrivateVPN works with a wide range of streaming services, such as Netflix, Disney+, Hulu, and more. If you find a server that works with a particular streaming service, you can add it to a favorites list, making it quicker to connect in the future.   

Torrenting is permitted via dedicated servers based in Sweden. Helpful features – though not available on all apps include port forwarding and both system-wide and app-specific kill switches to cut internet traffic if the VPN connection drops out.  

Account holders can connect up to 10 devices simultaneously, which is twice that of most VPNs. If you need yet more connections, you can manually configure PrivateVPN to work with some routers. 

PrivateVPN’s lightweight apps are available for Windows, macOS, iOS, Android and Amazon Fire TV.


  • Works with major streaming sites
  • Very fast speeds
  • Connections for up to 10 devices 


  • Small network of servers
  • Slow switching between servers
  • Kill switch is Windows only
  • Limited live chat

DEDICATED TO PRIVACY:Acts as its own server host and ISP. Operates a strict no logs policy and has a range of connection options for Comcast customers. Comes with a 30-day money-back guarantee.

6. IPVanish


IPVanish is unusual in that it operates its own network of several thousand servers. It’s undoubtedly fast, with no lagging or buffering while streaming 4K video or during gaming.

However, Comcast customers might find that it isn’t always easy to connect to their favorite streaming sites. I found that while Netflix worked, accessing services like Hulu and Amazon Prime Video didn’t.

Torrenting is allowed and IPVanish has a kill switch to stop internet traffic if the VPN connection drops out. There’s also an option for split tunneling for Android and FireOS users, which allows selected apps to pass through the VPN, leaving the rest to use a direct connection. Reassuringly, the company operates a true no-logs policy that has been independently audited.

IPVanish uses 256-bit encryption on the Wireguard protocol by default, while SHA512 is used for authentication. A DHE-RSA 2048 key exchange supports perfect forward secrecy, which means that past sessions can’t be decrypted if someone obtains the current decryption key. 

All IPVanish plans allow you to simultaneously connect as many devices as you like. Apps are available for Windows, macOS, iOS, Android, ChromeOS, Fire TV, and select routers. Alternatively, you can purchase a pre-configured router with IPVanish already installed.


  • Excellent connection speeds
  • Works with Netflix
  • Unlimited simultaneous connections


  • Only works with a few streaming services
  • No Linux app
  • Based in the US
  • Customer service can be sluggish

UNLIMITED CONNECTIONS: all of the devices in even the largest households. Fast, but not always good for streaming. IPVanish comes with a 30-day money-back guarantee. 

7. Private Internet Access

Private Internet Access

Private Internet Access (PIA) is a veteran provider that is fast, secure and a good option for Comcast customers keen to avoid bandwidth throttling. I used it to stream 4K video, video conference in HD, and play online games without any lag or buffering.

Torrenting is possible, and aided by unlimited bandwidth and port forwarding. A split tunneling feature means you can keep a P2P connection secure while turning the VPN off for other programs. A kill switch ensures that the flow of internet traffic will stop if the VPN connection drops out. 

PIA keeps your data secure using 128-bit AES-GCM encryption, though you can up it to 256-bit encryption if necessary. It keeps zero logs of what you do while connected, nor any metadata such as timestamps and IP addresses. I also like that you can pay for your subscription using cryptocurrencies and gift cards.

The provider has lightweight, user-friendly apps available for Windows, macOS, iOS, Android, Linux, and Amazon Fire TV. There are several OS-specific features, such as a snooze function that temporarily disconnects the VPN. This isn’t available on iOS. There’s also a secure browser for Android and iOS phones, which offers better privacy and security than the browsers the phones ship with. 


  • Solid speeds
  • Customizable app
  • Excellent privacy


  • Dated app design
  • Many countries with no servers
  • Doesn’t work with some major streaming services

DEDICATED TO PRIVACY: is reliably fast and provides excellent security and privacy. It comes with a 30-day money-back guarantee. 

8. Atlas VPN

Atlas VPN is able to stream a range of content without lag or buffering. It’s fast, secure, and a good choice for Comcast customers who want access to a range of streaming services.

Features include automatic startup and a kill switch, which stops internet traffic if the VPN connection drops out. There’s also the option of switching protocols, though Wireguard is usually by far the fastest.

Atlas VPN uses its own private DNS servers, and protects your data using AES-256-bit or ChaCha20 channel encryption, SHA-384 or Poly1305 authentication, and BLAKE2s for hashing. The company does not record your online activity or your real IP address.

You can connect using an unlimited number of devices simultaneously, which makes Atlas VPN a good choice for larger households. Subscriptions can be paid for using cryptocurrency like Bitcoin, Ethereum, and Ripple – thus granting you an extra degree of privacy. 

Simple and intuitive apps are available for Windows, iOS, Android, macOS, Android TV, Amazon Fire TV, and Linux Ubuntu. 


  • Works with most streaming services
  • Fast speeds
  • Unlimited simultaneous connections


  • Privacy policy a little vague
  • Relatively small server network
  • Customer service could be improved

GREAT FOR STREAMING: to access a range of streaming services and provides fast, secure connections. Atlas VPN comes with a 30-day money-back guarantee. 

Methodology: How I found the best Comcast VPNs

Given that Comcast poses a threat to both privacy and connection speeds, I’ve looked for VPNs that are fast, safe, and secure. To find the best Comcast VPN, I specifically considered:

  • Speed: Whether you’re streaming, gaming or transferring large files, it’s essential to have a VPN that is fast enough. I measure connection speeds to servers around the world and conduct regular speed tests.
  • Security: Comcast is eager to get hold of your data, which is why all of my chosen VPNs are leak-free and meet my rigorous standards for encryption
  • Privacy: We all know that ISPs like Comcast can spy on what we’re doing online, which is why it’s so important that your VPN doesn’t do the same. I check every VPN’s logging policy, and reject those that don’t meet my standards. 
  • Streaming services: A VPN isn’t much use if it has to be turned off every time you want to stream content, which is why I check providers against popular services such as Netflix, Disney+, BBC iPlayer, and more.
  • Ease of use: The best VPNs are easy to use, and should allow you to connect with a single click. If something’s wrong, they should provide decent customer support to put things right.  
  • Network size: As a general rule, the larger the VPN’s network of servers in a particular location, the more reliable it is. I check that recommended VPNs have enough servers, in enough places, to ensure stable connections. 

If you’re interested in a detailed look at my testing methodology, see how I test VPNs.

Can I use a free VPN?

I generally advise against using free VPNs. They tend to be under-funded and under-resourced, resulting in sub-par security and a restricted server network that is constantly over-loaded. To counter this they often impose data caps or limit bandwidth. 

Free VPNs tend to derive their income from advertising, which typically involves selling your data to third parties. Trackers are common and a majority of free VPNs have some kind of logging policy. The very worst – often unintentionally – carry malware that makes your device vulnerable to attackers.

In most cases it’s better to use no VPN rather than one of the freely available products. If you can’t pay much for a service, then check out my cheap VPN recommendations.

How to use a VPN with Comcast

It’s easy to get started with a VPN if you’re a Comcast customer. Just follow these steps:

  1. Visit the website of your chosen VPN and sign up.
  2. Download and install the relevant app for your device. All of the providers I recommend make their own VPN apps.
  3. Restart the devices on which the VPN has been installed.
  4. Open the VPN app and sign in.
  5. Select a server or let the app choose one for you.
  6. Press the connect button.
  7. Check that your connection is secure. This is normally indicated in the taskbar at the top of the screen.

Comcast VPN FAQs

Does Comcast throttle bandwidth?

Yes, Comcast is notorious for deliberately slowing down its customers’ internet speeds. This is primarily done to manage network congestion. Comcast will look at the websites you visit and decide whether to throttle your connection or not. 

This used to happen to people streaming Netflix – until the provider agreed to pay Comcast to stop. This set a precedent for ISPs to take money from internet companies who didn’t want their users’ bandwidth restricted. 

Subsequent legal wrangling has also led to the repeal of broadband privacy and net neutrality laws in the US. In essence, Comcast is now free to harvest its customers’ data and throttle their connections at will.

I therefore strongly recommend the use of a VPN at all times. NordVPN is the best choice for Comcast customers, but Surfshark and ExpressVPN are good alternatives. 

Is using a VPN with Comcast legal?

Yes, it is. There are very few countries where it’s illegal to use a VPN, and the US – where Comcast operates – isn’t one of them. For its part, Comcast states:

“You can use a Virtual Private Network connection just as long as it’s for your personal, non-commercial use, and it doesn’t violate our applicable terms of service and policies.”

Can Comcast tell if I’m using a VPN?

Comcast will be able to see the volume of internet traffic flowing to and from your device, and that this data is encrypted. This will indicate to it that you’re using a VPN. What matters, though, is that it can’t see which websites you’re visiting and what data you might be entering while there.
