SHIELD is a device-first fraud intelligence platform that helps digital businesses worldwide eliminate fake accounts and stop all fraudulent activity.
Powered by SHIELD AI, we identify the root of fraud with the global standard for device identification (SHIELD Device ID) and actionable fraud intelligence, empowering businesses to stay ahead of new and unknown fraud threats.
We are trusted by global unicorns like inDrive, Alibaba, Swiggy, Meesho, TrueMoney, and more. With offices in San Francisco, London, Berlin, Jakarta, Bengaluru, Beijing, and Singapore, we are rapidly achieving our mission - eliminating unfairness to enable trust for the world.
ShieldLabs identifies your visitors and detects anonymity at any level with up to 99% accuracy, so you can assess traffic quality and prevent abuse and fraud.
It covers the full spectrum of anonymity, from a clean visit to VPN, proxy, Tor, anti-detect browsers, browser automation, and other anonymity signals. Every visit gets a risk score from 0 to 100 with the named signals behind it, so you can see exactly why a score is what it is.
What you get
How it works
One JavaScript snippet, about 5 minutes to first signal. Results arrive through a REST API and signed webhooks, available on every plan.
Pricing
5,000 free identifications, no credit card, not time-limited. Paid plans are published and flat, self-serve from the first tier to the last.
Pricing scales with your traffic. Billing is per identification, and the rate per 1,000 goes down as you move up the tiers, so growth makes each identification cheaper rather than more expensive. Yearly billing saves 20%. Traffic above your plan keeps being identified and scored, billed at your plan rate.

SHIELD's answer
Most fraud solutions are web-first and rely heavily on personal data and static identifiers that are easily bypassed. They are also often focused on addressing fraud at specific checkpoints. SHIELD is device-first. Fraudsters can spoof data, accounts, and even identities, but they always need a device to act. This is why we stop fraud at the root.
ShieldLabs's answer:
Identification that holds. ShieldLabs recognises a returning visitor with up to 99% accuracy, through cleared cookies, incognito mode, IP rotation and months between visits, because the device identifier is computed from the device rather than stored in the browser. That cuts both ways: the same recognition that exposes one person running twenty accounts also lets you greet a good returning customer without making them prove who they are again.
Anonymity detection with up to 99% accuracy, at any level rather than a binary VPN yes or no:
Each arrives as a separate named signal, so you know which kind of anonymity was found, not just that something was.
The risk score comes apart. Every score from 0 to 100 arrives with the named signals that produced it, so you can see why a visit scored what it did instead of trusting a number you cannot inspect.
Patterns, already correlated. The work across accounts, devices and identities is done before you open the dashboard, pointing to multi-accounting, account sharing, account takeover and account farms operating behind one connection. A starting point for investigation that is waiting when you arrive.
The full detection stack is on every tier. The API and webhooks are included from the first plan, pricing is published, and signup is self-serve all the way through.
SHIELD's answer
Our plug-and-play SDKs and lightweight JavaScript snippets can be integrated in a matter of hours โ not weeks or months. Thereโs no training period required, enabling your team to start detecting fraud immediately. Most customers see tangible results on day one, with zero disruption to existing workflows.
ShieldLabs's answer:
Depth at a self-serve price. The level of anonymity detection that usually sits behind an enterprise conversation is available on the entry tier here, and API access is included on every plan rather than unlocked further up.
You can be running today. One JavaScript snippet, about five minutes to the first signal, and the whole path from the pricing page to a working integration is self-serve: no demo to book, no sales call, no quote to wait for. Evaluation happens on your own schedule and on your own traffic.
The score is explainable. When a legitimate customer gets caught by your rules, looking up why is a query rather than a guess.
Patterns arrive pre-computed. The correlation work across accounts and devices is done before you open the dashboard.
Traffic quality is a first-class view, not a by-product of scoring. The analytics dashboard gives you:
Your analytics tool tells you where traffic came from. This tells you what arrived. For anyone buying traffic, that turns a monthly ad invoice into something you can argue with.
Pricing is published and flat:
Your code makes the decision. ShieldLabs returns the signals and the score, so the logic specific to your business stays in your codebase where you can change it.
SHIELD's answer
SHIELD works with digital businesses across every region and industry where trust and safety are mission-critical. Our customers include global unicorns and fast-scaling platforms in mobility, fintech, e-commerce, igaming, digital identity, and more. If your platform faces fraud, or trust & safety challenges, SHIELD can help you eliminate malicious users and scale growth with confidence.
ShieldLabs's answer:
Two groups, and they come in through different doors.
Developers and technical founders, most often the CTO at a team of five to fifty. The product is API-first, so whoever evaluates it is usually whoever integrates it. They want the raw signals and intend to write the decision logic themselves rather than buy a service that makes the call on their behalf.
Growth, marketing and analytics people, who may never open the API. Once the snippet is in, the analytics dashboard is theirs: which traffic sources bring anonymized and high-risk visitors, what share of sessions is clean, how it all moves week to week. For anyone buying traffic that is a direct argument about ad spend. For anyone reporting on product metrics it is the difference between counting sessions and counting people.
Installation takes one person about five minutes, and the dashboard needs no code after that, which is why the buyer and the daily user are often not the same person.
By sector it clusters where a free tier, a promotion or a signup carries real marginal cost:
It also fits teams with no fraud problem at all. Recognising a good returning visitor is the same capability pointed the other way, whether that means personalising an experience or not asking someone to prove who they are twice.
SHIELD's answer
SHIELD deliver real-time device intelligence globally, with offices in San Francisco, Singapore, Jakarta, Dubai, London, Sรฃo Paulo, and more. We are a global team, which helps us stay close to the latest fraud trends, and our clients.
ShieldLabs's answer:
What you integrate is deliberately small. One ES module loaded from the CDN, and everything after that arrives through a REST API and signed webhooks. It assumes nothing about your stack.
There is an install guide for whatever you already use: JavaScript, React, Next.js, Vue, Angular, Svelte, Preact, React Native WebView, plus WordPress, Shopify and Tilda.
On WordPress, Shopify and Tilda that means no developer at all. The module goes where the platform already keeps custom code, and that is the whole integration.
Nothing to maintain afterwards. Detection keeps improving without you shipping an update, so what you install today gets better on its own.

ShieldLabs's answer:
ShieldLabs came out of four gaps that repeat across this category.
Who the tooling was built for. Everything that reliably identifies visitors and detects anonymity has been priced and packaged for enterprise buyers: a demo to book, a quote to wait for, a procurement cycle to survive. The teams losing the most to free-tier farming, promo abuse and fake signups are small and self-serve, and that path is not built for them.
What anonymity detection had been reduced to. In most stacks it is a side feature: a binary VPN yes or no bolted onto a product built for something else, usually resting on IP reputation lists that go stale as fast as residential proxy pools rotate through consumer addresses. Anti-detect browsers, the working tool of anyone doing multi-accounting at volume, are rarely a first-class signal at all.
Explainability. Most detection products return a number. When a paying customer trips over that number, the team has nothing to inspect and nothing to tell the user.
The work that begins after the purchase. A product that hands over raw signals has moved the problem rather than solved it, because someone still has to build the model, correlate across accounts and devices, and keep the whole thing current. Time to a first useful answer gets measured in weeks.
So the product was built around four commitments:
Anonymity as the product, not a checkbox. Device and network signals together, up to 99% accuracy in detecting anonymity from a clean visit through VPN, proxy, Tor and Privacy Relay to anti-detect browsers and browser automation, each surfaced under its own name.
Pricing published, stack whole. The full detection stack on every tier, self-serve from the first plan through the top one, so the path from landing page to first signal runs inside a single session.
Every score decomposable into the named signals behind it, so the customer's code owns the decision while ShieldLabs owns the evidence.
Usable on day one. One JavaScript snippet, about five minutes to the first signal, patterns already correlated rather than left as an exercise, and an analytics dashboard that reads without code, so the person who needs the answer is not waiting on the person who can write the query.
