Now, people who make apps work with cloud APIs, local containers, and test spots in many places. - Author: Partner - Tags: Featured, Proxy **Quick answer:** A system-wide VPN sends all traffic through one tunnel. This can slow down tasks on your computer. It can make dev tools stop working. If there is a problem, it can affect more things at once. When you use per-app proxy routing, it only sends the data you want through. There are rules that developers​ can read and update. For many years, the setup for developers was clear. You would connect to the VPN and work. All things went through the tunnel. That included package downloads, pulling Docker images, running test servers on your computer, and even music streaming in the background. It worked because you got your work done at the end. That model is breaking. Zscaler's 2025 VPN Risk Report talks about this change. The report is from a survey of 632 IT and security people. It shows that 65% of them want to get rid of their VPNs in a year. Developers feel the same thing. The tunnel gives an all-or-nothing approach and it keeps making their work hard. ## **The Hidden Cost of Routing Everything** **Quick answer:** A full tunnel adds delay to every request. It can also clash with localhost and container networking. It makes fixing problems harder. Developers deal with this the whole day. When you turn on a full-tunnel VPN, things slow down. npm installs can take a long time. A teammate might not reach the right place when using a staging URL. Docker containers may also not find their way to your host. A lot of developers then switch the VPN on and off all day. Security teams really don't like it when people do this. Tools like[ ](https://proxytool.app/?utm%5Fsource=scalenut)[proxytool](https://proxytool.app/) work in a different way. You pick which apps or domains use a proxy, like the staging API or just one browser. Everything else moves straight and stays quick. ## **Security Is Pushing in the Same Direction** **Quick answer:** VPN gateways are now often targeted. A full tunnel lets one device that is hacked see and get much data. A narrow tunnel with limited routes makes sure each connection can only get to a small set of data. Verizon's[ ](https://www.verizon.com/business/resources/executivebriefs/dbir-2026-executive-summary.pdf?utm%5Fsource=scalenut)[2026 Data Breach Investigations Report](https://www.verizon.com/business/resources/executivebriefs/dbir-2026-executive-summary.pdf?utm%5Fsource=scalenut) shows that attackers get in most often by taking advantage of weak spots in systems, at 31%. Only 26% of top risks from CISA’s list of problems are fully fixed. On average, they took 43 days to fix. VPN appliances are right at the center of this problem. In Zscaler’s survey, 92% of people said that not fixing VPN issues could cause ransomware. This is the same idea behind zero trust. TechTarget says old VPNs[ ](https://www.techtarget.com/searchsecurity/post/Why-zero-trust-models-should-replace-legacy-VPNs?utm%5Fsource=scalenut)[extend too much trust to anyone who connects](https://www.techtarget.com/searchsecurity/post/Why-zero-trust-models-should-replace-legacy-VPNs?utm%5Fsource=scalenut), but new models let you get to only the resources you need. Per-app routing puts this way of working right on the developer's computer. ## **What Per-App Proxy Routing Looks Like in Practice** **Quick answer:** You make rules that fit an app, website, or port. Then, you send it to a certain proxy or straight. The rules stay in a file. You can check them, share them with people, and go back to an old one. A developer's rule set might look like this: - **Staging and internal APIs** use the company system to connect. - Scraping or geo-testing scripts use a rotating pool of connections to get data. - **Package managers, Git and localhost** stay direct. - Everything that is not known goes straight through, or it will be stopped on a machine that is locked down. Because the rules are clear, they're easy to read. A new hire gets the same file. A problem gets fixed once, not on every laptop. And when one goes down, only the traffic behind it is affected. Audits are easier too. When security asks where traffic goes, you answer with a file instead of taking a guess. ## **Making the Switch Without Breaking Your Workflow** **Quick answer:** Pick one app to start with. Copy your rules into the new app. Use both old and new for one week. After that, stop using the old setup. Most teams do not make a switch overnight. They start out with the app that gives them the most trouble. Many times, this is a browser for testing or a single CLI tool. After that, they work on more apps. You should look at times before and after, since builds and test runs often get faster when your traffic does not have to take a long way through another gateway. If you are already using a routing tool and want something new, see if you can bring your rules in without doing all the work again. A good guide on how to[ ](https://proxytool.app/blog/migrate-from-proxifier?utm%5Fsource=scalenut)[migrate from Proxifier](https://proxytool.app/blog/migrate-from-proxifier) can save you a lot of time. Rule making and proxy setups do not match up one to one most of the time. ## **FAQ** **Is per-app proxy routing a replacement for a company VPN?** Not every company works the same. Some still want you to use a VPN for some systems. Per-app routing takes care of everything else in a more exact way. **Does it work with containers and WSL?** Usually, but you should check to make sure. Containers and WSL use their own type of adapters for the network. The rules may need to be set for them directly. **Is a proxy as secure as a VPN?** A proxy does not make your traffic safe by itself. You have to use HTTPS or an encrypted way when your data is important. ## **Conclusion** The system-wide VPN was good when all things were inside one office. Now, people who make apps work with cloud APIs, local containers, and test spots in many places. If you let each app go where it should, and not send all the things through one way, it can be faster. This way, people who try to break in have less to use.
