Many AI bots actually tell you their name. OpenAI's bot says "GPTBot," Anthropic's says "ClaudeBot,". To confirm a crawler is legitimate and not spoofed, cross-check the request IP against the crawler's officially published IP ranges. * **How to set it up:** If you use a CDN or hosting platform, check their dashboards first. Cloudflare, Vercel, and Netlify already sit on your server logs and package this information in a dashboard. For self-hosted sites, your web server (Nginx, Apache) keeps access logs that you can download or search with command-line tools. * **Limitations:** This only works on bots that choose to be honest. Both user-agent string and IP range based defenses can be easily evaded. The bots that are actually dangerous don't announce themselves. And browser-based agents like ChatGPT's Atlas or [OpenClaw](https://cside.com/blog/how-openclaw-agents-bypass-bot-detection) are less likely to self identify through user-agent strings. ### Method 2: Specialized AI agent detection tools ![Image 3: AI agent detection list in the cside dashboard](https://cside.com/images/ai-agent-detection-list-cside-dashboard.webp) Dashboard screenshot of the cside AI agent detection platform A new category of detection tools emerged specifically to address AI agents, because the problem goes well beyond scraping and crawling. [78% of CTOs at financial institutions surveyed by Accenture](https://bankingblog.accenture.com/agentic-payments-commerce) expect a spike in fraud driven by AI shopping agents. * **How it works:** These tools monitor dozens of signals across 4 detection layers: identity (who the visitor claims to be), network (where they're connecting from), browser environment (what their runtime looks like), and behavior (how they actually interact with the page). By cross-referencing signals across all four layers, they can catch agents that pass any single check on its own. * **How to set up:** Most of these tools (such as [cside](https://cside.com/en/solutions/ai-agent-detection)) are installed by adding a JavaScript snippet to your site, similar to how you'd install an analytics tool. Once cside is installed it instantly monitors activity across all four signal layers and shows you a dashboard of visitors that are human, which are known agents, and which are suspicious. _We break down signals we use for our own AI agent detection further down in this blog._ ### Method 3: Traditional bot detection tools Tools like Cloudflare Bot Fight Mode and Akamai Bot Manager were built to catch automated traffic. They're the most common starting point for bot defense, and one many teams already have in place. * **How they work:** These tools analyze incoming requests using a combination of IP reputation, TLS fingerprints (JA3/JA4), header consistency, and challenge-response mechanisms like CAPTCHAs. * **How to set up:** Most CDN providers offer a basic bot protection toggle in their dashboard. Other dedicated platforms may require a JS snippet or reverse proxy setup, plus a contract conversation. **Limitations:** Plenty of security vendors slapped "AI bot detection" onto their product pages in the last year without adequately changing how their detection works under the hood. Low cost or free "add ons" for AI agent detection largely rely on looking for basic automation patterns or CAPTCHA style checks, missing many of the malicious agents. > Some of our engineers at cside ran a test by deploying AI agent based bots against two major bot detection platforms, and [we bypassed detection on 81 out of 100 attempts.](https://cside.com/research-report-future-of-web-security-2026) Now, to be fair, there is often a massive difference between the free/add on features versus the dedicated enterprise bot management products _from the same company_. Tools like Cloudflare's Enterprise Bot Management go deeper with behavioral signals. But they also come with enterprise pricing that most companies can't justify. Many of the companies we speak to don't realize how much malicious traffic they allow under the impression that toggling a "bot protection" button from a WAF vendor is all the defense they need. ### Bonus method: Analytics tools (Google Analytics, PostHog) ![Image 4: Google Analytics screenshot showing a spike of AI agent traffic](https://cside.com/images/google-analytics-ai-agent-traffic-spike.webp) _We noticed a spike from China even though that country is geo-blocked in Cloudflare. Upon inspection, this spike correlated with a rise in "Chrome" related traffic._ Google Analytics and PostHog are not bot detection tools. But we wanted to include them as a free, instant (most websites already use these tools), and no-code option that you can play with. To be clear - by default analytics tools like GA4 will miss AI agent traffic and categorize them as "real visitors". They can't distinguish between a real visitor and a Playwright script browsing your site in headless Chrome. This is why our research found a [275% spike in forum discussions about bot traffic](https://cside.com/research-report-future-of-web-security-2026) that bypassed the usual defense mechanisms and showed up onto Google Analytics. **But with custom parameters you can catch _some_ agentic browser traffic:** * A rise in traffic from "Chrome" as the browser. Most automation frameworks default to Chrome or "Chromium". * Sessions from countries you've already geo-blocked. For example, our Cloudflare set up blocked China but GA4 still shows a ton of traffic spikes from that region. * Sudden traffic from specific _cities_, often Chinese cities, that make no sense for your business. * A massive spike in traffic from a particular screen resolution (e.g. 1270x980) and the same geographical area. This can indicate a bot farm that uses thousands of the same device. * An unexplainable spike from a random country. We had Norway go from near zero to 10,000+ sessions in a single month. This indicates VPNs/Rotating proxies used at scale by bots. ## The types of AI agent traffic on your website When people think of AI agent traffic, the first thing that comes to mind is crawlers. Crawlers do make up a large portion of automated traffic, but they're only one category. * **AI search crawlers:** Agents from AI-powered search engines like Perplexity and Google AI Overviews. They visit your site to pull content into AI-generated search results. * **LLM training crawlers:** Bots like GPTBot, ClaudeBot, and CCBot that scrape your content to train or update large language models. Most declare themselves in their User-Agent strings. These can be problematic for websites with content they want protected (artwork, writing, music) and not used to train LLMs. * **Scrapers:** Specifically, the ones that come from outside the major AI platforms. Aggregation services pulling your data into competing products, competitors monitoring your pricing, or piracy operations copying your content at scale. * **User action agents (information retrieval):** A consumer asks ChatGPT to research your product or tells Claude to compare prices across three vendors. The platform sends an agent to your site that browses pages, reads content, and brings the answer back. * **User action agents (task execution):** Agents deployed by consumers to fulfill tasks. Perplexity Comet completing a purchase, a browser automation downloading a PDF or filling out a contact form. They click buttons, submit forms, and navigate flows just like a human would. * **Fraudulent agents:** Agents built for explicitly malicious purposes. For example - testing batches of stolen credit cards against your payment flow or creating dozens of accounts to abuse referral bonuses. These are familiar fraud patterns, but AI agents make them cheaper to deploy and harder to catch. AI search crawlers and LLM training crawlers can be caught with relatively basic methods. If you are worried about fraudulent agents, a [specialized AI agent detection tool](https://cside.com/en/solutions/ai-agent-detection) that is purpose built for fraud detection is a better option. ## AI bot detection signals that we use at cside | **Signal Layer** | **What It Looks At** | | --- | --- | | **Identity** | Who the visitor claims to be. User-Agent strings, bot signatures, and cross-checks against known crawler lists. | | **Network** | Where the request comes from. IP reputation, ASN analysis (datacenter vs. residential), TLS fingerprinting (JA3/JA4), and geographic consistency between IP location and browser settings. | | **Browser/Device** | Whether the browser environment is real. Automation framework artifacts (CDP traces), Browser API consistency (WebGL, Canvas, Audio), and hardware plausibility checks. | | **Behavioral** | How the visitor actually interacts with the page. Typing speed, navigation timing, form fill patterns, mouse movements, and click placement. | ### Identity signals * The most straightforward way to identify an AI agent is by checking who they claim to be. This is what robots.txt was built for. Crawlers like GPTBot, ClaudeBot, and GoogleBot identify themselves through User-Agent strings or other signatures/bot identifiers. * At cside, we maintain a list of known crawler signatures and cross-check incoming User-Agents against it, including publicly flagged aggressive or malicious crawlers. * **The limitation is that identity signals are easily spoofable.** This system is only reliable for bots that choose to self declare. According to Ahrefs, [up to 98% of AI traffic is from major platforms](https://ahrefs.com/blog/ai-traffic-study/) (OpenAI, Anthropic, Google, Meta) which can usually be identified through identity signals. Other emerging approaches tackle the agent identity problem more seriously. For example [Browserbase](https://www.browserbase.com/identity), a platform that lets users create browser automations, issues an AI agent "passport" that is a cryptographically verified credential. If this becomes industry standard across browser automation tools, AI traffic filtering would become easier for organizations. ### Network layer signals ![Image 5: Network layer signals for AI agent detection](https://cside.com/images/network-layer-signals-ai-agent-detection.webp) * IP reputation and ASN analysis: Every request originates from an IP address tied to an Autonomous System Number (ASN). Datacenter ASNs (AWS, GCP, Azure) are a strong indicator of automation. Residential IPs are harder to flag, but cross-referencing against known proxy networks helps. * TLS fingerprinting (JA3/JA4): When a browser connects to your site, the TLS handshake creates a fingerprint that identifies the real client software. If someone claims to be Chrome but their TLS fingerprint looks like a Python script, you've caught a mismatch. * Geographic consistency: Cross-reference IP geolocation with the browser's timezone and language settings. If the IP resolves to Frankfurt but the browser reports a timezone of Asia/Shanghai and a language of zh-CN, something doesn't add up. ### Browser/device layer signals * Automation framework artifacts. Playwright and Puppeteer use the Chrome DevTools Protocol to control the browser, and this leaves clues. Some that we look for are `cdc_` prefixes in window objects or accessibility elements that have been stripped. * Browser API consistency: WebGL, Canvas, and Audio context should tell a coherent story about the device. When a browser reports a powerful GPU through WebGL but produces Canvas output that doesn't match or when the Audio context fingerprint is missing entirely, something has been tampered with. * Hardware plausibility: The declared GPU, screen resolution, and operating system need to make sense together. A visitor with a 375x812 mobile resolution reporting a desktop NVIDIA GPU on Linux is not a real device profile. ### Behavioral signals * Behavioral analysis focuses on how a visitor uses your site. Typing speed, time between page navigations, how forms get filled out, scroll depth, mouse movement patterns. Even sophisticated automation tends to produce patterns (or anomalies) that can be identified. * This layer requires constant evolution. Agents get smarter, and yesterday's detection signal may be patched by today. At [cside](https://cside.com/en/solutions/ai-agent-detection), we continuously collect behavioral data and run AI models against it to surface new patterns as agent behavior changes. Button click placement is a concrete example. One of our engineers, Martijn Cuppens, analyzed three popular browser extension based tools: * One clicked every button at the exact center. Another always clicked slightly off-center to the right. The third centered most of the time but would occasionally place a click at a random position within the button, an intentional attempt to introduce noise. This is one of hundreds of behavioral signals we collect and analyze. Each one alone might not be conclusive. Together, they build a profile that's very difficult to fake. ## Misconception: AI agents will only use websites through APIs and MCP You'll hear this a lot: websites will shift to APIs and MCP and the browser won't matter anymore. It's a prophetic narrative, but it doesn't hold up and is certainly not the case today: * [Google published a guide on making your website agent-ready](https://web.dev/articles/ai-agent-site-ux), and it explicitly covers visual UI optimization. Agents interact through DOM parsing and visual screenshots. If Google thought websites were going API-only, they wouldn't be telling you to make your buttons clearer and your layouts more stable. * [A study by Carnegie Mellon researchers](https://aclanthology.org/2025.findings-acl.577.pdf) found hybrid agents using both browsing and API calls significantly outperformed API-only interactions. Agents used both modalities in 77.7% of tasks. Even with a good API available, they still fell back to the browser. Why this matters: agents browse like humans because that's what works best. They click, scroll, fill forms, and navigate page by page. That behavior is visible at the browser layer. You can't observe an API call the same way you can observe an agent working through your checkout flow. The browser is where you catch them. ## Why AI agent detection is different than regular bot detection ### Stealth browsers and anti-detect frameworks ![Image 6: Google search trends for stealth browser](https://cside.com/images/google-search-trends-stealth-browser.webp) * There's a whole category of automation tools now built specifically to be invisible to bot detection such as Playwright with stealth plugins or browser-use. They suppress the `navigator.webdriver` flag, spoof Canvas and WebGL fingerprints, and try to strip out the Chrome DevTools Protocol traces that most detection tools look for. * This isn't a small corner of the internet. [Playwright's npm installs](https://cside.com/research-report-future-of-web-security-2026) tripled to over 35 million monthly downloads. Google searches for "stealth browser" went from flat to [continuous all time highs in the last two years.](https://cside.com/research-report-future-of-web-security-2026) ### Locally hosted automation Traditional bots ran on cloud servers (datacenter IPs or virtual machines). AI agents increasingly run on real consumer hardware. Someone using a Claude browser extension on their personal laptop sends requests from a legitimate residential IP, a real browser, and authentic device fingerprints. Attackers can replicate this behavior by running Playwright on local devices (Mac Minis for example) which seems indistinguishable from a consumer using a device. ### From scripted patterns to reasoning-based automation Traditional bots followed scripts. Step one, step two, step three. That predictability is what made them catchable. AI agents now reason about the page, decide what to do next, and adapt when something unexpected happens. CAPTCHAs are not a reliable backstop now either. AI vision models now solve CAPTCHAs faster and more reliably than humans. ## How to distinguish between malicious AI agents and consumer AI agents There's a new vector to consider when it comes to bot detection. A chunk of "AI agent traffic" comes from consumers sending agents to your site. * Perplexity Comet makes purchases on behalf of users. Amazon Buy for Me checks inventory and completes orders. Base44 books reservations. These are real products with real consumer adoption, not prototypes. As covered in our [AI agent research report](https://cside.com/research-report-future-of-web-security-2026), "user action" AI bot traffic increased by over 15x throughout 2025. Blocking all automation now means blocking potential revenue or at least slowing down the buying experience. ### From "bot or not" to intent classification For years, bot detection was binary. Is this a bot? Yes? Block it. This breaks down when your customers are the ones sending the bots. Or when you value the SEO/AEO visibility that comes from crawlers. * **The new approach is intent classification:** Instead of asking "is this a bot," you ask "what is this bot trying to do?" The answer determines whether you allow it, monitor it, challenge it, or block it. Signals feed into a risk score. If a visitor tested 17 credit cards in three minutes, that's a card enumeration attack. If a session shows automation signals and is creating multiple accounts on your site, that might be multi-accounting (multiple accounts to exploit free trials or sign-up bonuses). Bot detection, [fingerprinting](https://cside.com/en/solutions/fingerprinting), and account activity signals work together to trigger enforcement actions when automated activity looks like fraudulent activity. ## Why your website analytics tools don't catch AI agent traffic AI crawlers and scrapers like GPTBot and ClaudeBot don't execute JavaScript at all. They request your HTML, extract the content, and move on. Your analytics snippet never fires, so these visits never appear in GA4, PostHog, or Amplitude. Browser-based AI agents have the opposite problem. They operate in real browsers and generate session data that looks like a human. So GA4 and other analytics tools count them as real users. ## What to do when you detect AI agent traffic ### Don't default to blocking It's tempting to block everything that looks automated, but blanket blocking hurts you in two ways. You lose visibility into what's actually happening on your site, and you block consumer agents that are trying to purchase your products or recommend your brand through AI search. ### Adaptive response strategies to AI agent traffic * **Redirect or serve agent-specific content:** An insurance company we work with found bots running through their quoting workflow to scrape pricing. Their solution: when a bot was detected in the quoting flow, the final step showed a "contact us" screen instead of the generated quote. No price data leaked to competitors/aggregation platforms. In the case of a false positive, a human could still continue the sales process. * **Customize the experience.** Rather than blocking an agent, give it a purpose-built view. A page that acknowledges "we've identified you as an AI agent, here's an optimized version" lets consumer agents get the information they need while your human visitors see the full experience. We have a full guide that covers different fraud scenarios here: [How to block fraudulent AI agents on your website](https://cside.com/blog/how-to-block-ai-agents-on-your-website-guide). ## How cside solves AI bot and agentic browser detection ![Image 7: cside AI agent detection dashboard](https://cside.com/images/product/ai-agent-detection-cside-dashboard.webp) cside is a web security platform specialized in watching the browser runtime. cside's [AI agent detection](https://cside.com/en/solutions/ai-agent-detection) is purpose-built to identify fraudulent AI agents on your website.

FAQ Frequently Asked Questions How do I detect AI agents on my website? Start with server logs to catch crawlers that self-identify, then check your analytics for traffic anomalies. For the agents that actually matter (stealth browsers, locally hosted bots, fraudulent automation), you need a specialized detection tool that monitors browser-layer signals like runtime artifacts, behavioral patterns, and device consistency. How do I detect AI crawlers on my website? Most AI crawlers declare themselves through User-Agent strings (GPTBot, ClaudeBot, PerplexityBot). Check your server logs or CDN dashboard for these identifiers, and cross-check request IPs against each crawler's published IP ranges to confirm they're not spoofed. This catches the well-behaved ones. Crawlers that spoof their identity require deeper detection. What's the difference between an AI crawler and an AI agent? Crawlers fetch your content (usually for search indexing or model training) and leave. Agents browse your site, click buttons, fill forms, and complete tasks. Crawlers are mostly identifiable. Agents are a harder problem as they can commit fraudulent actions. Can AI agents bypass CAPTCHA? Yes. AI vision models solve CAPTCHAs faster and more reliably than most humans now. CAPTCHAs create more friction for your real visitors than for the bots they're supposed to stop. How much of my website traffic is bots? Globally, bots account for over half of all web traffic according to multiple reports. Data from Ahrefs show that 63% of websites receive AI traffic. Do AI agents respect robots.txt? Some do, many don't. Academic research found that AI assistants and AI search crawlers re-check robots.txt less frequently than any other bot category. And robots.txt only covers bots that voluntarily comply. It was designed in 1994 for a different internet. How do I detect OpenClaw bots on my website? OpenClaw agents operate through browser extensions and don't self-identify in their User-Agent strings, so server logs won't help. You need browser-layer detection that catches automation artifacts and behavioral anomalies. Should I block all AI agent traffic? No. A growing share of your visitors are consumers using AI agents to shop, compare prices, and research products. Blocking everything means blocking revenue. Classify by intent and respond accordingly. How do I know if AI agents are costing me money? Check two things: your infrastructure bills for unexplained spikes (especially on usage-based platforms like Vercel), and your analytics for traffic patterns that don't match reality. If sessions doubled but conversions didn't move, something is off. Can browser-based detection catch agents running on someone's personal laptop? Yes. The device and IP might be completely legitimate, but the agent still has to execute code to interact with your page. Click patterns, form fill behavior, DOM interactions, and runtime inconsistencies are all visible at the browser layer regardless of where the agent is hosted. ## Monitor and Secure Your Third-Party Scripts Gain full visibility and control over every script delivered to your users to enhance site security and performance.
