Why B2B teams are switching from Google Analytics

Mode A uses a daily rotating cryptographic salt (SHA-256) to create session identifiers. The salt is deleted after rotation, making it mathematically impossible to reconstruct visitor identities. No cookies, no fingerprinting, no personal data stored. You don't need a DPA, and you never need a consent banner.

Sensor uses a zero-cost open-source IP intelligence stack (GeoLite2 ASN databases, ipverse metadata, bad-ASN filtering) to identify which companies are visiting your site in real-time. Google Analytics has no equivalent feature — you'd need to buy a separate tool and integrate it yourself.

GA4's interface requires significant training — Google themselves offer a multi-course certification program. Sensor's dashboard is designed for immediate comprehension: clear KPIs, intuitive funnel visualization, and AI-generated insights. Your team starts getting value on day one.

The Sensor tracking script is under 600 bytes — 75x smaller than Google Analytics' ~45 KB script. This means zero impact on Core Web Vitals, no render blocking, and faster page loads. It loads asynchronously with the defer attribute by default.

With GA4, achieving GDPR compliance requires careful configuration: consent mode setup, data retention policies, IP anonymization, and ongoing monitoring. With Sensor Mode A, compliance is architectural — there's nothing to configure because no personal data is collected in the first place.

GA4 requires cookies — which means you need a consent banner under GDPR, UK GDPR, and ePrivacy. Studies show 30–50% of visitors reject cookies, and that traffic becomes invisible in your analytics. Sensor Mode A uses no cookies at all, so every visitor is tracked from the first pageview — no consent prompt, no data gaps.

Google now requires Consent Mode v2 for EU traffic. That means implementing a CMP (consent management platform), mapping consent states to GA4 tags, configuring ad_storage / analytics_storage signals, and testing across browsers. Sensor skips all of this — there's nothing to consent to when no personal data is collected.

With GA4: you lose them entirely. No pageviews, no events, no attribution — they become a blind spot. Google's "cookieless pings" in Consent Mode provide modelled estimates, not real data. With Sensor: nothing changes. Every session is captured with full accuracy regardless of consent choices, because there's no consent required.
