A major shift is happening in the world of web automation and proxy usage in 2026. AI agents — software programs that can browse websites, log in to accounts, fill in forms, and complete multi-step tasks on their own — are becoming very common in business operations.
Companies are using them to collect competitive data, automate research, monitor prices, and handle all kinds of repetitive online work.
But there is a serious technical problem: most proxy setups that worked fine for simple scraping are breaking down when used with AI agents.
What Is the Problem With Rotating Proxies for AI Agents?
The problem is called session persistence. When an AI agent is working through a multi-step task — like logging in to a website, navigating to a product page, and extracting structured data — it needs to stay connected as the same user throughout the whole process.
Rotating residential proxies, which change your IP address with every request or every few minutes, break this session.
The website sees a login from one IP address, then a product page request from a completely different IP address.
This looks suspicious. The session gets flagged or cancelled.
The solution that is working best right now is ISP proxies with a fixed, static IP address. These give your AI agent one consistent identity throughout the entire task.
The website sees the same IP address from start to finish, which looks like normal human browsing behaviour.
ISP proxies are real addresses from legitimate internet service providers, which means they also have the same trust level as residential IPs.
Anti-bot systems like Cloudflare treat them much more kindly than data center IPs.

Why ISP Proxies Are Becoming the Go-To Solution in 2026
Leading proxy providers including Bright Data, Oxylabs, SOAX, and Decodo are all reporting rising demand for ISP proxy allocations specifically from teams building AI agent infrastructure.
The shift from ‘how much data can I collect?’ to ‘how reliably can my AI agent complete a workflow?’ is changing what customers are looking for in a proxy service.
Speed and volume are still important, but session stability is becoming the number one priority for automation use cases.
If your team is building or using AI agents to automate web-based tasks, the first thing to check is what type of proxies you are using.
If you are on a rotating residential plan, test whether switching to a static ISP proxy improves your success rates and reduces errors. For most multi-step automation workflows, the answer is a clear yes.
The cost per gigabyte may be slightly higher, but the cost per completed task is almost always lower when your sessions stop getting broken mid-workflow.
