Report Bugs and Get Rewarded

Our unwavering security pledge

The Efani solution is one of a kind for different reasons. However, at the core of our operations, we take security seriously. It is why we are happy to welcome skilled security researchers from anywhere around the world who are interested in identifying a weakness. See how our security level works here.

If you find weakness or vulnerability in Efani, please share with us as soon as possible.  First, you may support the entire community in preventing attacks on their phones. Second, you may be eligible for a reward through our Bug Bounty Program.


To participate in our bug bounty program, you agree to have read and agree to observe all provisions outlined in the scope. Our Bug Bounty Program only allows researchers to test our servers and procedures. That means our customers’ security testing is off-limit unless you get their explicit permission.
When you join the program, we can ship our SIM card to you to test locally, and if we can establish a cordial relationship and corporation, you may be eligible to participate in our official bug bounty program.

Eligibility and Disclosure Policy

The fine print

It’s important to mention that we use OWASP Risk Methodology which may be different from the one you’ve. In calculating the severity of the report, we mainly consider the likelihood of exploiting the issue, not just the technical impact. We may modify the terms of this program or terminate this program at any time. We won’t apply any changes we make to these program terms retroactively. If you have any other questions about our security, don’t hesitate to contact us at Thank you for helping keep Efani and our users safe!
