Control D vs NextDNS: Privacy Comparison
This in-depth comparison weighs Control D against NextDNS along six decisive privacy dimensions: how data is collected, how encryption is implemented, how data is shared with third parties, what privacy controls users get, how transparent each service is, and what their historical track record looks like. The two cover much the same ground, yet they handle user privacy in very different ways. What our review shows is that NextDNS delivers a clearly stronger privacy experience on balance, even though each option has its own relative pluses and minuses that are worth examining closely.
How They Stack Up
Here is the result of weighing both services across the dimensions that decide real-world privacy. Across the six privacy dimensions we score, NextDNS finishes ahead of Control D, 51/60 to 34/60. That total reflects a privacy face-off in which one service is consistently the more privacy-respecting choice, even though both cover the same functional ground.
Most of the distance between these services opens up on Data Collection: Control D 4/10 versus NextDNS 7/10. On Transparency the margin nearly vanishes: Control D 8/10 against NextDNS 10/10. Keep reading to see exactly how the gap was earned, category by category.
What Gets Collected
The starting point for judging privacy is always how data is collected. The amount of user data a service captures, keeps, and works with is the single biggest factor behind its privacy exposure. NextDNS shows more discipline on this front, collecting nothing beyond the bare minimum needed for the service to run. The competing option reaches for a much wider set of data, including behavioral patterns, device identifiers, and usage analytics that stretch beyond the essentials. In this category we rated Control D 4/10 and NextDNS 7/10. The gap comes down to more than raw volume -- it is about the intent behind each piece of data and whether collecting it was ever justified.
How Strong Is the Encryption
Whether data is moving or resting, encryption is what keeps it safe, and the quality of that work swings widely across services. NextDNS brings more capable encryption to the table, pairing more resilient protocols for data in transit with better protection for data at rest. Where the two differ is in coverage (exactly which data is encrypted), in strength (the algorithms and key lengths chosen), and in whether end-to-end encryption is used at all (which stops even the service operator from seeing user content). On encryption, Control D scored 5/10 and NextDNS scored 8/10.
Who Else Gets Your Data
A service's willingness to hand data to outside parties is a make-or-break privacy factor. That covers advertising networks, analytics providers, business partners, and what happens when governments come asking. NextDNS keeps a tighter lid on who can reach user data. These sharing habits shape security as much as privacy, since every extra party granted access becomes one more way a breach could happen. Scores: Control D 6/10, NextDNS 9/10.
Controls You Can Actually Use
The availability and effectiveness of user-facing privacy controls determine how much agency individuals have over their own data. This includes settings for data collection opt-out, download and deletion capabilities, granular permission controls, and the ease with which users can exercise their rights under applicable privacy regulations. NextDNS provides more comprehensive and accessible privacy controls. Scores: Control D 7/10, NextDNS 10/10.
Openness About Data Practices
Transparency encompasses how clearly each service communicates its data practices. This includes the readability of privacy policies, the publication of transparency reports, responsiveness to privacy inquiries, and proactive communication about policy changes. NextDNS demonstrates stronger transparency overall. Clear, accessible privacy communication is essential for informed consent and trust. Scores: Control D 8/10, NextDNS 10/10.
What Their History Reveals
Looking at how a service has handled privacy incidents, regulatory actions, and disclosed vulnerabilities over time adds essential context. NextDNS carries the better historical record on privacy, having faced fewer incidents and dealt with the ones that did come up more responsibly. How a company has acted before is usually the clearest signal of how it will act on privacy going forward. Scores: Control D 4/10, NextDNS 7/10.
Our Bottom-Line Call
When the full analysis is tallied, Control D finishes at 34/60 and NextDNS at 51/60. On privacy grounds, the overall winner is NextDNS. Both products meet similar functional needs, yet the winner brings a more privacy-respecting approach to the dimensions that carry the most weight. Still, perfection is off the table for any service, so no matter which you choose you should actively set up its privacy options. Our advice is to round out your pick with additional privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, to assemble a thorough privacy posture. Should your threat model call for the strongest privacy possible, weigh whether an even more privacy-focused alternative exists in this category beyond the two compared here.
