How does ShieldLabs detect paywall bypass?

ShieldLabs scores the risk of every visitor before the paywall loads, so bypass attempts surface at the gate instead of after the content is given away. It collects 100+ device, OS, browser, and network signals on the first visit; surfaces anonymity signals that point to a disguised session; links the session to a persistent identifier so the same person reappears even after they reset; and returns a 0–100 risk score with a full signal breakdown. ShieldLabs hands your team the score and the evidence; you set the threshold that triggers verification or a block.

What are common paywall bypass methods?

Most paywall bypass falls into four patterns, all of which try to look like a brand-new visitor each time content is requested. Free-tier cycling: clearing cookies or using incognito mode to reset a metered counter.; VPN-based geo-arbitrage: using an egress IP in another country to reach region-locked content.; Subscription sharing: one set of credentials used by more people than the plan allows.; Anti-detect browser access: spoofing the device and browser to defeat fingerprinting.

Can ShieldLabs detect incognito mode and cookie clearing?

Yes. ShieldLabs ties each visit to a persistent identifier that survives the resets people use to game a metered paywall. Cleared cookies leave the DeviceID intact. Incognito and private windows are flagged as a fresh-but-recognized session. IP rotation does not break the persistent identifier. ShieldLabs returns the same VisitorID on every cycle, so the tenth incognito attempt is recognized as the first visitor, and surfaced before the next request loads the content.

How does ShieldLabs compare to paywall software like Piano or Pelcro?

They solve different jobs and work best together, paywall software runs the gate, ShieldLabs scores who is at it. Paywall and subscription platforms handle gating, billing, and metered access logic. ShieldLabs adds the identification and risk layer, scoring every visitor before they reach the gate. ShieldLabs drops in alongside your existing paywall through a single JavaScript snippet.

Will ShieldLabs block real subscribers who use VPN?

No. ShieldLabs never blocks anyone on its own, it returns a score and the evidence, and your team owns the decision. A VPN by itself is a low-weight signal that flags a session for review, not a block. The score rises only when signals stack together. ShieldLabs gives you 5,000 free identifications to measure the false-positive rate on real traffic first.

Does ShieldLabs detect subscription fraud and streaming fraud?

Yes, subscription fraud and streaming fraud share the same root signal as paywall bypass: one user wearing many identities, or one identity worn by many users. ShieldLabs surfaces all three the same way, subscription fraud, streaming fraud, and paywall bypass, through persistent visitor identification, anonymity signals, and pre-built Patterns.
