If you care about Internet privacy, you have probably come across services such as Cloudflare WARP, Proton VPN and NextDNS.
At first glance, combining them seems straightforward: use NextDNS for private DNS, add WARP or a VPN for encrypted traffic, and you should have a highly private Internet connection.
In practice, it is a little more complicated.
I have learned that security is rarely about finding one perfect product. It is about understanding what each layer protects, where its limitations are, and which organisation you are trusting with your data.
That is the approach I have taken in this comparison.
I am looking at two common configurations:
Cloudflare WARP + NextDNS
Proton VPN + NextDNS
The short answer is that Cloudflare WARP is generally the better choice if your priority is performance, while Proton VPN is the stronger choice if your priority is hiding your public IP address and using a conventional VPN architecture.
Neither solution provides complete anonymity or perfect security.
And that last point is worth taking seriously.
There is no such thing as a 100% secure system
One of the most important lessons in cybersecurity is that there is no system that is completely secure.
Every operating system, application, VPN protocol, DNS service, router, browser and cloud platform can contain bugs or vulnerabilities.
Even security products themselves can have vulnerabilities.
A service can be well designed, independently audited and operated by a reputable company and still have a security issue discovered tomorrow.
That is not necessarily evidence that the technology is useless. It is simply the reality of modern computing.
Cybersecurity is about reducing risk, not eliminating risk completely.
This is why security professionals commonly rely on defence in depth: multiple independent layers that reduce the impact when one control fails. CISA similarly describes defence in depth as a layered approach rather than relying on a single security solution.
The same principle applies to personal Internet privacy.
Using encrypted DNS is useful.
Using a VPN can be useful.
Keeping software updated is useful.
Using multi-factor authentication is useful.
But none of these controls should be treated as a guarantee that you are completely protected.
There is always another potential weakness, misconfiguration, software bug, compromised endpoint or previously unknown vulnerability.
That is why I prefer to ask:
“What risk does this technology reduce?”
rather than:
“Does this make me completely secure?”
DNS and VPN are not the same thing
Before comparing WARP and Proton VPN, it is important to understand the difference between DNS privacy and VPN privacy.
DNS, or Domain Name System, translates a domain such as example.com into an IP address.
When you use normal ISP-provided DNS, your DNS provider is typically your Internet service provider.
With DNS-over-HTTPS, or DoH, the DNS request is encrypted between your device and the DNS provider.
NextDNS supports encrypted DNS and adds additional features such as filtering, tracking protection and security policies.
However, encrypted DNS does not mean that your entire Internet connection is protected by a VPN.
A VPN operates at a different layer.
A VPN creates an encrypted tunnel between your device and the VPN provider and routes Internet traffic through that tunnel.
In simple terms:
NextDNS protects DNS queries.
A VPN protects and routes Internet traffic.
That distinction is fundamental.
Cloudflare WARP + NextDNS
Cloudflare WARP is designed to route traffic through Cloudflare’s network.
If you configure WARP in a way that allows NextDNS to remain your DNS provider, the architecture can look like this:
Your device → NextDNS via DoH for DNS
Your device → Cloudflare WARP → Internet for other traffic
This combination can be attractive for people who want good performance while retaining NextDNS filtering.
NextDNS can continue handling DNS filtering and security policies while WARP handles the traffic tunnel.
For everyday web browsing, this is a relatively simple setup.
Why Cloudflare WARP can be fast
Cloudflare operates a large global network, and WARP is designed around that infrastructure.
For many users, this can provide good latency and throughput without the performance penalty associated with some traditional VPN configurations.
However, there is no universal answer.
A user in Singapore may experience completely different routing from someone in Sydney, London, Frankfurt, New York or San Francisco.
Your ISP’s peering arrangements also matter.
This is why I would always benchmark your own connection rather than assuming that an Internet speed comparison from another country applies to you.
Proton VPN + NextDNS
Proton VPN follows a more traditional VPN architecture.
When you connect to Proton VPN, your Internet traffic is routed through a Proton VPN server.
Websites generally see the VPN server’s public IP address rather than the public IP address assigned by your ISP.
A suitable NextDNS configuration can use Proton VPN’s supported Custom DNS functionality.
The basic architecture is:
Your device → encrypted Proton VPN tunnel → Proton VPN server → Internet
DNS → NextDNS through the VPN tunnel
This is different from simply running NextDNS independently on your device.
The important consideration is that DNS traffic should remain within the VPN tunnel rather than accidentally bypassing it.
Why use NextDNS with a VPN?
A VPN already provides DNS handling, so why use NextDNS?
The answer is control.
NextDNS offers features that some users may prefer, including custom blocklists, tracker blocking, security filtering, logging controls and granular DNS policies.
For users who have already invested time in building a NextDNS configuration, keeping it while using a VPN can be useful.
However, DNS configuration needs to be handled carefully.
Running several independent DNS and VPN applications at the same time can introduce routing conflicts or DNS leaks.
More security software does not automatically mean more security.
A badly configured combination can sometimes be worse than a simpler, correctly configured setup.
Which is faster: WARP or Proton VPN?
For general Internet usage, I would expect Cloudflare WARP + NextDNS to be faster in many situations.
That includes normal web browsing, video streaming, software downloads and general Internet access.
Proton VPN can still be very fast, particularly when using WireGuard and a nearby VPN server.
The actual result depends on:
Your ISP
Your location
VPN server location
Network congestion
Internet routing
Peering
Distance to the destination
Protocol overhead
For example, a Proton VPN server located close to you may provide excellent performance, while a poorly routed WARP connection could perform worse.
Therefore, the correct answer is not “WARP is always faster”.
It is:
WARP is generally the lower-overhead option, but your own network determines the final result.
Cloudflare WARP + NextDNS: advantages
The biggest advantage is performance.
WARP is often a good choice for users who want better network privacy without the overhead associated with a traditional VPN service.
Other advantages include:
Good everyday performance
Large global network
Low latency on many networks
NextDNS filtering can be retained
Relatively simple configuration
Useful protection against local DNS interception when correctly configured
Cloudflare WARP + NextDNS: disadvantages
The biggest limitation is that WARP should not be treated as an anonymity service.
Cloudflare becomes an intermediary for your traffic.
That means you are shifting some trust away from your ISP and towards Cloudflare.
It also does not prevent other forms of tracking.
If you log into Google, Microsoft, Apple, Facebook, your bank or another online service, that service can still associate activity with your account regardless of your network IP address.
Browser fingerprinting, cookies and other tracking mechanisms can also identify users.
Proton VPN + NextDNS: advantages
The main advantage is IP privacy.
A conventional VPN routes traffic through a VPN server and replaces your normal public IP address from the perspective of websites.
Other advantages include:
Protection against local network monitoring
DNS leak protection
VPN kill switch functionality
WireGuard support
Ability to combine VPN routing with NextDNS filtering
Better separation between your ISP connection and your public Internet identity
This makes Proton VPN a more conventional choice when the objective is to hide your residential or mobile IP address.
Proton VPN + NextDNS: disadvantages
The primary trade-off is performance.
Your traffic has to travel through the VPN server before reaching its final destination.
If the VPN server is geographically distant or the route is congested, latency can increase.
There is also more configuration complexity when adding a third-party DNS provider.
A poorly configured third-party DNS setup can potentially bypass the VPN’s intended DNS routing.
For that reason, I prefer a supported Custom DNS configuration rather than forcing multiple independent DNS mechanisms to operate simultaneously.
What can your ISP see?
This is one of the most common questions about VPNs and DNS services.
Without encrypted DNS, your ISP may be able to observe DNS requests.
With DNS-over-HTTPS, those DNS requests are encrypted between your device and the DNS provider.
However, encrypted DNS does not make the entire connection equivalent to a VPN.
With a properly configured VPN, your ISP can generally see that your device is communicating with the VPN service, but the contents of the VPN tunnel are encrypted.
That is a major difference between using NextDNS alone and using a VPN.
However, it is important not to oversell this protection.
A VPN does not make all network metadata disappear.
Your ISP may still see connection timing, bandwidth patterns and the fact that you are connected to a VPN provider.
Privacy technologies reduce visibility. They do not create magical invisibility.
What can NextDNS see?
When you connect directly to NextDNS, NextDNS receives your DNS requests.
Depending on your configuration and the information available to the service, those requests can be associated with your network connection.
When NextDNS is used through a Proton VPN tunnel, the DNS traffic travels through the VPN connection.
This can prevent NextDNS from directly seeing your normal ISP-assigned public IP address.
This creates an interesting division of trust:
Proton VPN handles the traffic tunnel.
NextDNS handles DNS.
The ISP provides the underlying connection.
The website receives the VPN’s public IP address.
No single component necessarily has the complete picture.
Is Proton VPN + NextDNS more private than WARP + NextDNS?
For IP privacy, I would choose Proton VPN.
For speed and simplicity, I would choose WARP.
That does not mean Proton VPN is universally “more secure”.
Security depends on the threat model.
If your concern is an ISP seeing DNS queries, encrypted DNS may already address a significant part of the problem.
If your concern is a website seeing your residential IP address, a conventional VPN is more appropriate.
If your concern is anonymity from multiple parties, neither solution should be treated as sufficient on its own.
What about security vulnerabilities?
This is another area where I think the industry sometimes oversimplifies things.
Cloudflare can have vulnerabilities.
Proton can have vulnerabilities.
NextDNS can have vulnerabilities.
VPN applications can have bugs.
Operating systems can have vulnerabilities.
Browsers can have vulnerabilities.
Routers can have vulnerabilities.
Even encryption protocols and libraries can eventually have weaknesses discovered by researchers.
The important question is how quickly vulnerabilities are discovered, disclosed, patched and mitigated.
This is one reason I place more value on vendors that maintain their software, publish security information and respond appropriately to security issues.
There is no permanent state of “secure”.
Security is an ongoing process.
A system that was secure yesterday can become vulnerable today because of a newly discovered bug.
That is why keeping your operating system, browser, VPN application, router firmware and security software updated is just as important as selecting the right privacy service.
Defence in depth matters
I prefer a layered security model rather than depending on a single product.
For a normal home user, that could mean:
Encrypted DNS
A reputable VPN when appropriate
HTTPS
Strong passwords
Password manager
Multi-factor authentication
Automatic software updates
Secure Wi-Fi configuration
Router security
Browser privacy controls
Regular backups
No single layer needs to be perfect.
The goal is to make compromise more difficult and reduce the consequences if one layer fails.
This is consistent with the broader cybersecurity principle of defence in depth: multiple protective and monitoring layers are more resilient than relying on one “silver bullet” security technology.
Which setup would I choose?
If my main priority were speed:
Cloudflare WARP + NextDNS.
If my main priority were hiding my public IP address:
Proton VPN + NextDNS.
If I already relied heavily on NextDNS and wanted a traditional VPN:
Proton VPN + NextDNS through the VPN provider’s supported Custom DNS configuration.
If I needed strong anonymity:
I would look beyond conventional VPNs and consider technologies specifically designed for anonymity, such as Tor.
The important part is to define the threat model first.
Do not buy a VPN simply because an advertisement says it provides “complete privacy”.
Ask what information you are trying to protect and from whom.
My practical conclusion
For everyday Internet use, I would give Cloudflare WARP + NextDNS the advantage in performance.
It is a compelling combination for users who want encrypted DNS, DNS filtering and additional network privacy without necessarily needing a traditional VPN.
For stronger IP privacy, I would choose Proton VPN + NextDNS.
It provides the more familiar VPN model, where Internet traffic is routed through a VPN server and websites normally see the VPN’s IP address.
There is no universally “best” setup.
The best architecture depends on your threat model, location, ISP, applications and tolerance for performance overhead.
And perhaps the most important lesson is this:
Do not confuse privacy with anonymity, and do not confuse security with perfection.
There is always the possibility of a configuration a potential hole.
There is always another bug that has not been discovered yet.
There is always the possibility of a configuration mistake.
Good security is therefore not about finding a magical product that makes you 100% safe.
It is about reducing exposure, using multiple layers, keeping systems patched, understanding what each provider can see and accepting the remaining risk.
That is how I approach network security after more than 15 years in IT.
Frequently Asked Questions
It depends on your objective.
WARP is generally the better choice for performance and simplicity.
Proton VPN is the better choice if hiding your public IP address and using a conventional VPN architecture are important.
Is NextDNS a VPN?
No.
NextDNS is a DNS service with privacy, filtering and security features.
It does not replace a VPN.
Does NextDNS hide my IP address?
No.
NextDNS can encrypt DNS queries, but it does not hide your public IP address from websites.
Can I use NextDNS with Cloudflare WARP?
Yes.
If you want NextDNS to remain your DNS provider, use a WARP configuration that does not take over DNS.
Can I use NextDNS with Proton VPN?
Yes.
Using NextDNS through Proton VPN’s supported Custom DNS configuration is a cleaner approach than running a separate DNS implementation that could bypass the VPN.
Does a VPN hide everything from my ISP?
No.
A VPN encrypts the traffic inside the VPN tunnel, but the ISP can generally still see that you are connected to a VPN and can observe certain metadata.
Does Proton VPN make me anonymous?
No.
It can hide your normal IP address from websites, but accounts, cookies, browser fingerprinting and other tracking technologies can still identify you.
Is WARP an anonymous VPN?
No.
WARP provides network privacy and traffic protection, but it should not be treated as an anonymity service.
Which is better for gaming, WARP or Proton VPN?
It depends on your network.
Measure latency, jitter and packet loss to your actual game servers.
A VPN that is geographically closer is not necessarily better if the underlying route is poor.
Which is better for streaming?
Both can provide good performance.
WARP may have lower overhead, while Proton VPN provides the traditional VPN capability of changing the public IP address seen by websites.
Streaming services may restrict or detect VPN traffic, so results can vary.
Is Proton VPN + NextDNS completely secure?
No.
No Internet security setup is 100% secure.
Software vulnerabilities, configuration errors, compromised devices, zero-day vulnerabilities and other threats can affect even well-designed systems.
The objective should be risk reduction through layered security.
Is Cloudflare WARP + NextDNS completely secure?
No.
The same principle applies.
It can provide useful privacy and security improvements, but it cannot eliminate every possible vulnerability or attack.
Should I use WARP and Proton VPN together?
Generally, I would not.
Running multiple VPN or tunnelling systems simultaneously can create routing, DNS and performance problems.
Choose the architecture that matches your threat model instead of assuming that more VPN layers automatically mean more security.
What is the best privacy setup for an ISP?
For a simple, performance-focused configuration:
Cloudflare WARP + NextDNS.
For stronger IP privacy:
Proton VPN + NextDNS.
For high-anonymity requirements:
Consider an anonymity-focused technology such as Tor rather than relying on a conventional VPN alone.
What is the safest Internet security setup?
There is no single safest setup for everyone.
A sensible approach is defence in depth: encrypted connections, secure DNS, reputable security software, strong authentication, regular updates, secure Wi-Fi, backups and good security practices.
The goal is not 100% security.
The goal is to make attacks harder, reduce exposure and limit the damage when one layer fails.
