OpenDNS vs Google DNS: Privacy Comparison
Here we put OpenDNS head-to-head with Google DNS across the six privacy factors that matter most: their data collection practices, encryption implementation, third-party data sharing, user privacy controls, transparency, and historical track record. While both products address similar requirements, the philosophies they bring to protecting users diverge sharply. Our assessment finds that Google DNS provides a noticeably better overall privacy experience, although neither service is without trade-offs that deserve a careful, detailed look.
Reading the Scorecard
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Google DNS finishes ahead of OpenDNS, 43/60 to 37/60. That total reflects a side-by-side review 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: OpenDNS 7/10 versus Google DNS 8/10. Data Collection is where they come closest, a mere 1-point gap (7 vs 8 out of 10). Continue for the full reasoning behind each category score.
What Gets Collected
Every privacy assessment starts with data collection. How much a service gathers, stores, and processes about its users is what ultimately drives the privacy risk of using it. Google DNS takes a leaner approach here, capturing only the data strictly required to make the service work. Its rival pulls in a wider net of information -- behavioral patterns, device identifiers, and usage analytics that go well past what the core features actually need. Our marks were OpenDNS 7/10 and Google DNS 8/10 in this area. What separates them is not merely how much is gathered but why it is gathered and whether it is truly needed.
Encryption Implementation
Encryption protects user data both in transit and at rest, and the implementation quality varies dramatically between services. Google DNS implements stronger encryption measures, including more robust protocols for data in transit and better protection for stored data. The specific encryption implementations differ in their coverage (which data is encrypted), their strength (which algorithms and key lengths are used), and whether end-to-end encryption is employed (preventing even the service provider from accessing user content). OpenDNS scored 8/10 while Google DNS scored 9/10 for encryption.
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. Google DNS 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: OpenDNS 4/10, Google DNS 5/10.
What You Can Manage Yourself
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. Google DNS provides more comprehensive and accessible privacy controls. Scores: OpenDNS 5/10, Google DNS 6/10.
Transparency
At its core, transparency is about how clearly a service tells users what happens to their data. That means how understandable the privacy policy is, whether transparency reports exist, how promptly privacy inquiries are addressed, and whether changes to policy are flagged proactively. Google DNS is the stronger performer on transparency overall. Without clear and accessible privacy communication, informed consent and trust are impossible. Scores: OpenDNS 6/10, Google DNS 7/10.
Historical Track Record
A service's history of privacy incidents, regulatory actions, and responses to vulnerabilities provides important context. Google DNS has a stronger historical record on privacy, with fewer incidents and more responsible handling of the issues that have arisen. Past behavior is often the best predictor of future privacy practices. Scores: OpenDNS 7/10, Google DNS 8/10.
Overall Verdict
Adding everything up, our full analysis lands OpenDNS at 37/60 and Google DNS at 43/60. For privacy, the overall winner is Google DNS. The two cover much the same functional ground, but the winner takes a more privacy-respecting stance across the dimensions that count for the most. Even so, no service is flawless, and whichever option you pick, you should always tune its privacy settings deliberately. We suggest pairing your choice with extra privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, so you end up with a well-rounded privacy posture. And if your threat model demands the very highest level of privacy, it is worth asking whether an even more privacy-focused alternative exists in this category beyond the two compared here.
