3DS does more than stop fraud

It’s easy to think of 3DS as a trade-off between fraud protection and customer friction. Used well, it helps you approve more good customers and reduce fraud.

oe44kqinic85uzpg00sbcd7vmzyy3tvpbgrr4lvyijndc9c38rfnoi4r169b5yy0cyhxqysg076aqqbjlm5ttmd2k5b9nufvhn2qrpz93d4yv2tjbaepa6visu1uanuxzfq4bw9dp07si4fybq9xzkb0izxpm90t2te3ro2oaogmu1vfkgu6z14kw3tz4egcnckd9s

The right flow
for every transaction

Your fraud model decides how risky a transaction looks, and you choose one of three flows per transaction. Here’s what would happen to 100 transactions under each flow based on our global 3DS performance data.

Liability shift on fraud-related chargebacks, including transactions that need a challenge, so you can accept orders your fraud model might block.

Authenticate once, route to any PSP

A 3DS authentication from your PSP only works with that PSP. If a payment fails and you retry on another processor, your customer has to authenticate again.

From weeks of work
to two simple steps

Most 3D Secure implementations take weeks to build and require significant engineering effort. Evervault reduces this to two simple steps.

Unable to reach directory server

7+ integration steps across multiple deployments, which can take weeks or even months of engineering work.

Create a 3DS Session

Pass the session ID to our client SDK

const tds = ev.ui.threeDSecure('tds_57aa862f8bf7');
 
tds.on('success', () => {

tds.mount();

One API call. Mount our SDK. We handle all orchestration, browser flows, challenges, and edge cases, so you don’t have to.

Keep customers in your checkout

Redirecting customers to their bank's page breaks the checkout, adds a page load, and can fail when browsers block third-party cookies. Evervault embeds challenges directly in your checkout flow with fully customizable inline modals, supported on browser and mobile.

See what's working, and what isn't

Every ACS, directory server, and issuer returns different codes and formats. Evervault turns them into one clear view, so you can see how 3DS is affecting acceptance rates and fraud.
