[cside Claims vs Evidence](https://www.g2.com/products/cside/claims-vs-evidence) # cside Claims vs Evidence ## Claim: “The Fingerprint Events API returns a bot field for every identification call, covering AI browser agents such as OpenAI Operator, Claude for Chrome, and Perplexity Comet, as well as headless browsers like Puppeteer, Playwright, and Selenium, and classic scrapers.” ##### Supported by reviews. A relevant reviewer reports strong fingerprinting and AI-agent detection capabilities, supporting the claim's general functionality. However, the review does not establish that a bot field is returned on every identification call or confirm coverage of each named browser agent, headless browser, and scraper. - “They have really strong data collection for fingerprinting and AI agent detection with flexibility on how we can use the data.” [Read Full Review](https://www.g2.com/survey_responses/12873342) Last updated Oct 5, 2026 Source: [https://cside.dev/pricing](https://cside.dev/pricing) ## Claim: “Identifies AI agents, headless browsers, and autonomous bots by their browser fingerprint, scripted cadence, and session behaviour.” ##### Supported by reviews. A relevant reviewer reports strong fingerprinting and AI-agent detection capabilities, consistent with the claim. The reviews do not independently detail detection of headless browsers, scripted cadence, or session behaviour. - “They have really strong data collection for fingerprinting and AI agent detection with flexibility on how we can use the data.” [Read Full Review](https://www.g2.com/survey_responses/12873342) Last updated Oct 5, 2026 Source: [https://cside.dev/pricing](https://cside.dev/pricing) ## Claim: “Detects Magecart, web skimming, e-skimming, and malicious third-party scripts in 100% of visitor sessions with no sampling.” ##### Supported by reviews. Reviewers generally report comprehensive monitoring and detection of third-party scripts, though the reviews do not establish the specific 100% coverage or no-sampling guarantee stated in the claim. - “cside proxies our JavaScript by injecting its script first on the page, which allows it to monitor third-party scripts” [Read Full Review](https://www.g2.com/survey_responses/12189954) - “You can see every script, where it comes from, what it’s doing, and whether it’s compliant or risky.” [Read Full Review](https://www.g2.com/survey_responses/11779495) - “if not, they detect/block it and let me know.” [Read Full Review](https://www.g2.com/survey_responses/11417308) Last updated Oct 5, 2026 Source: [https://cside.dev/pricing](https://cside.dev/pricing) ## Claim: “Add one script tag to your site and cside begins monitoring immediately with no performance impact.” ##### Mixed support from reviews. Reviewers describe cside as simple and non-invasive to implement, but another reviewer reports that it can sometimes introduce minimal latency, which conflicts with the claim of no performance impact. - “Integration was simple and non-invasive. The implementation required little to no development effort” [Read Full Review](https://www.g2.com/survey_responses/12189954) - “It can sometimes introduce minimal latency.” [Read Full Review](https://www.g2.com/survey_responses/11000460) Last updated Oct 5, 2026 Source: [https://cside.dev/pricing](https://cside.dev/pricing) ## Claim: “It automates PCI DSS 4.0.1 compliance for requirements 6.4.3 and 11.6.1, and detects Magecart and web skimming attacks.” ##### Supported by reviews.
