AI browsers that can navigate sites, fill in forms and complete tasks on your behalf, Perplexity’s Comet, OpenAI’s Atlas, and Google’s Gemini integration in Chrome, moved from novelty to genuinely widely used tools through 2025 and into 2026. They browse the web differently than a human clicking through pages manually, and that changes what you should actually want from a VPN running alongside them.
Why agentic browsing changes the privacy calculation
A traditional VPN’s job is straightforward: hide your IP address and encrypt your traffic between your device and the sites you visit. An AI browser adds a layer on top of that, an agent visiting multiple sites in quick succession on your behalf, sometimes logging into accounts, filling forms, or comparing prices across retailers. Each of those site visits still goes through your network connection, so a VPN still protects that traffic the same way it always has. What’s new is the volume and pattern of that traffic: an agent completing a multi-step task can generate dozens of rapid requests to different domains in a way that looks different from normal human browsing, which is worth understanding before you assume your VPN setup behaves identically to before.
Best VPNs for AI browser use compared

Why speed matters more here than with normal browsing
An AI browsing agent working through a multi-step task, comparing flight prices across five sites, say, is more sensitive to connection latency than a person reading one page at a time, since delays compound across each step of the task rather than only affecting a single page load. NordVPN, ProtonVPN, Surfshark and Mullvad all scored a full 5/5 on raw speed in our testing, which matters more here than the usual difference between a fast and merely adequate VPN would for ordinary browsing.
The no-logs question is more important than ever
If an AI browser is completing tasks that involve logging into accounts or handling anything sensitive on your behalf, an audited no-logs VPN matters more than it might for casual browsing, since you want assurance that the network layer underneath the agent isn’t itself a point where your activity gets recorded. NordVPN’s seven audits, ProtonVPN’s KPMG review, and Mullvad’s real-world police test are the strongest track records available, and any of the three is a reasonable choice to run underneath an AI browser doing meaningful work on your behalf.
Does a VPN interfere with AI browser functionality?
In our testing, none of the four VPNs above caused any AI browser to malfunction or slow down beyond the expected general VPN overhead. The one thing worth watching is geo-restricted content: if an AI agent is instructed to check pricing or availability on a site, and your VPN is set to a server in a different country than you actually are, the agent may return results for that server’s location rather than your own, which can be useful or misleading depending on what you asked it to do. Being deliberate about which VPN server location you’re connected to matters more with an AI browser doing the browsing than it does when you’re clicking through pages yourself and can immediately notice if something looks off.
A quick word on trust with agentic tasks
Handing browsing tasks to an AI agent means trusting it with more than a search bar; if it’s filling forms or comparing accounts on your behalf, it may be handling logged-in sessions, saved payment details, or personal information you’d normally type in yourself. A VPN protects the network path that traffic travels over, but it has no bearing on what the AI browser itself does with your data once a page loads, which is a separate trust question worth thinking through independently of any VPN decision.
Should you run a VPN on an AI browser by default?
Yes, for the same reasons you’d run one on a normal browser: hiding your IP address from every site the agent visits, protecting the connection on public Wi-Fi, and avoiding ISP-level visibility into what an increasingly large share of your daily browsing looks like. The agent doing the clicking instead of you doesn’t change any of those underlying reasons, it just means more of your daily traffic is now generated automatically rather than manually, which if anything makes the case for a VPN stronger, not weaker.
What to watch for as agentic browsers mature
This is a fast-moving space, and how agentic browsers handle networking, proxies and VPN interaction is likely to keep changing through 2026 as usage grows. Watch for browser-specific settings that let you control connection behavior more granularly, and check your VPN provider’s own guidance periodically, since several major providers have started publishing compatibility notes specifically for AI browser tools as the category has grown. If you rely on an AI browser for anything involving payment details or account logins, treat it with the same caution you’d apply to a human assistant with access to those same accounts.
Comet, Atlas and Gemini: any meaningful differences?
Each of the major agentic browsers approaches networking slightly differently under the hood, but from a VPN user’s perspective the practical experience is similar across all three: your VPN sits at the operating system or browser network level, and every request the agent makes, whether it’s Comet checking a price, Atlas filling out a form, or Gemini summarizing a page in Chrome, passes through the same encrypted tunnel as your manual browsing would. None of the three currently require a different VPN configuration than a standard browser. If that changes as these products add more advanced networking features, such as running tasks through their own cloud infrastructure rather than your local connection, the VPN’s role in protecting that traffic could shift, and it’s worth revisiting your setup if a provider announces a change like that.
A practical setup that works well
Connect your VPN before opening an AI browser, choose a server location that matches where you actually want results to come from, and enable the kill switch as you would for any other browsing session, since an agent mid-task with a dropped VPN connection is arguably a worse outcome than a human noticing a stalled page load themselves. Beyond that, using an AI browser doesn’t require anything fundamentally different from your existing VPN setup, just slightly more attention to server location given how directly it can affect the agent’s results, and slightly more attention to which accounts you let an agent touch in the first place.
NordVPN pairs strong speed with the deepest audit history, making it the safest default to run underneath an AI browser handling real tasks. Proton VPN is the better value pick if budget matters more than having the single fastest option.
