Online ads and trackers follow you everywhere, leaking data and slowing browsing. We tested five VPNs that filter ads, trackers, and malware at the DNS level—here are the ones actually worth buying.

Swiss jurisdiction, open-source apps, and NetShield DNS-level blocking with a free tier available.
Online ads and trackers follow you across the web, quietly leaking behavioral data and dragging down page loads. A VPN with built-in ad and tracker blocking kills two birds with one stone: it encrypts your traffic while filtering out ad domains, tracking pixels, and known malware hosts at the DNS level—before they ever reach your device.
This guide compares five VPNs that do exactly that, evaluating their blocking mechanisms, privacy jurisdictions, pricing, and device limits. Whether you want the most comprehensive protection, the best value, or the strongest privacy guarantees, there's a pick below for you.
Most VPN ad blockers operate at the DNS level: when your device requests a domain that serves ads or trackers, the VPN's DNS resolver refuses to resolve it, so the connection never happens. This is powerful because it works across every app on your device—not just your browser. In-app ads on mobile games, trackers embedded in desktop apps, and malicious domains are all caught before they can load.1
This is a meaningful advantage over browser extensions like uBlock Origin, which only filter traffic inside the browser. VPN-level blocking also saves bandwidth and battery on mobile, since blocked domains never download a single byte. That said, DNS-level blocking is less granular than content filtering—it can't strip specific elements from a page the way a browser extension can. The two approaches complement each other, and many users run both.
| VPN | Blocking Feature | Scope | Jurisdiction | Device Limit |
|---|---|---|---|---|
| NordVPN | Threat Protection | Ads + trackers + malware | Panama | 10 |
| Surfshark | CleanWeb | Ads + trackers + malware | Netherlands | Unlimited |
| Proton VPN | NetShield | Ads + trackers | Switzerland | 10 |
Threat Protection (formerly known as CyberSec) is the most comprehensive built-in blocker among major VPNs. It filters ads, trackers, and known malware domains at the DNS level, and it also scans downloaded files for malicious content.1 Paired with NordVPN's large server network and consistently strong speeds, it's the pick we'd recommend to most people.
NordVPN supports up to 10 simultaneous connections and operates under Panama's privacy-friendly jurisdiction. Additional features like Double VPN and Meshnet round out a well-rounded package. If you want one tool that handles encryption, ad blocking, and malware protection without juggling multiple subscriptions, this is it.

Surfshark's CleanWeb ad-blocker is included on every plan, not gated behind a higher tier.2 That alone makes it the standout value pick. Add unlimited simultaneous device connections—rare in the VPN space—and you have a service that covers an entire household for less than many competitors charge for a single line.
CleanWeb blocks ads, trackers, and malware domains. Surfshark is headquartered in the Netherlands and offers features like Dynamic MultiHop and NoBorders mode for restrictive networks. For budget-conscious users who want solid ad and tracker blocking without compromise, Surfshark is hard to beat.
Proton VPN's NetShield blocks ads and trackers at the DNS level, and the service backs it up with some of the strongest privacy credentials in the industry.3 Based in Switzerland, Proton VPN publishes open-source apps, operates Secure Core servers that route traffic through privacy-friendly countries, and offers a functional free tier—unusual among premium VPNs.
NetShield is available on paid plans and gives users a choice between blocking only malware, or blocking ads and trackers as well. For users who care deeply about jurisdiction, transparency, and the ability to audit the software they run, Proton VPN is the clear choice.
IVPN is built for users who want proof, not promises. The service offers anti-tracking features alongside open-source clients and a no-logs policy that has been independently audited.4 Based in Gibraltar, IVPN supports multi-hop VPN configurations and gives advanced users granular control over their connection.
IVPN's blocking isn't as feature-rich as NordVPN's Threat Protection, but its commitment to transparency—publishing audits, open-sourcing code, and maintaining a clear privacy stance—makes it the pick for users who prioritize knowing exactly what their VPN is doing. It supports up to 7 devices.
CyberGhost keeps things simple. Its built-in ad and malware blocking requires no configuration—just toggle it on—and the app's interface is among the most approachable in the category.5 With a large server count and a generous money-back guarantee, it's a low-risk entry point for users who want ad blocking without a steep learning curve.
Headquartered in Romania, CyberGhost supports up to 7 simultaneous connections. It won't satisfy power users the way IVPN or Proton VPN might, but for someone who just wants ads gone and traffic encrypted with minimal fuss, it gets the job done.
A final note: VPN-level blocking is excellent for broad, device-wide protection, but it doesn't fully replace a good browser extension. Running both gives you the best of both worlds—DNS-level filtering for apps and system-wide coverage, plus element-level content filtering for the browser.
