Phone Interview

A cryptocurrency exchange hired Hacken to provide penetration testing services and other support. After an initial round of tests, the team identified weaknesses and solutions to overcome them.

Internal stakeholders are impressed with the work Hacken has completed so far. An organized team, they’ve managed the project well, never letting the six hour time difference get in the way of productivity. Customers can expect an experienced and professional partner.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of a cryptocurrency exchange with offices in China and Singapore.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Hacken?

The security of our system is always our top priority, and we needed help from a professional in this area.

SOLUTION

What was the scope of their involvement?

Hacken has provided penetration testing for our website as well as our Android and iOS app. They identified issues and ran another round of tests after we made fixes.

They’ve also provided bug reporting, mediation services, and support.

What is the team composition?

Evgenia (Co-Founder & CEO) is my main contact.

How did you come to work with Hacken?

We approached a few companies, and we found Hacken to be the most professional. They had good experience and a strong technical team.

What is the status of this engagement?

We started working with Hacken in March 2020, and it’s ongoing.

They found issues with our security certificates after the retesting, and it took us 3–4 months to obtain new certificates and release the products into production. That extended our timeline.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Hacken has delivered more than we expected. We’re quite satisfied with them.

How did Hacken perform from a project management standpoint?

We have a time zone difference of about six hours, but we’ve managed to communicate effectively. We have regular teleconferences, and they always respond quickly during working hours.

What did you find most impressive about them?

They’re quite professional in the cybersecurity area.

Do you have any advice for future clients of theirs?

So far, so good. I don’t have any specific suggestions.
