Thanks OTP.

We’ll take

it from here

Hackable, fakeable, spoofable, swapable:

it’s time to move on from OTP.

BigHen’s authentication solutions extends the broad reach of OTP with a never-hacked physical layer of security. We make mobile authentication safe again.

Favored by financial services, software vendors, MNOs…and hackers

Everyone loves OTP. It’s easy. It has 100% reach. It’s also massively vulnerable to SIM swapping, phishing and interception. It’s time to stop leaving customer identity exposed. It’s time to move on from OTP.

A Strong Layer of Physical Security

Everyone’s got them. Every mobile device (legacy devices, too).

Tablets, PCs, IoT devices…even cars and appliances. The SIM (eSIMs, too) packs a powerful security punch. Now, BigHen turns SIMs into a seamless, yet ironclad, authentication solution, too.

No More

SIM Swap

BigHen is like SIM super glue. We bind unique device and SIM identifiers. And any change in the SIM or device – like SIM swap or phone replacement – is detected, enabling web services to prevent malicious log-ins.

Nothing

To Hack

There’s not much to hack on BigHen's SIM applets. Not much code. No personal data. That’s why even if the SIM-based BigHen applet was compromised, there’s just nothing to steal. Kind of like breaking into a safe…and finding it empty.

Never

Been Hacked

It's true. The SIM has never been hacked. That makes using it (eSIMs, too) for authentication much safer than complex, code-heavy solutions.

100%

Reach

Smartphone, legacy devices, wearables, IoT… BigHen works with any device and any OS.



0%

Friction

No account creation. No app installs. BigHen makes authentication seamless, silent and super easy for end-users.

Simple

Integration

SaaS-based API implementation means you can get up and running on BigHen F-A-S-T, without impacting your existing authentication solutions.
