BACKGROUND

Introduce your business and what you do there.

I’m the managing director at Wealthsite, a wealth management platform.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Nexa IT?

We needed someone to help us make sure that the environment in our application was secure from any threats of malicious intent.

SOLUTION

What was the scope of their involvement?

We hired Nexa IT to perform a penetration test on our application. We started the project by going through several sales meetings to try to get an understanding of the services they’re offering us, after which they came back with a statement of work. This included all the details about the process, the deliverables, our responsibilities, and their pricing proposal.

Once we agreed to their proposal, we sent over the information they would need such as IP addresses and several login credentials. They broke down the project into two parts — the first part involved testing to see if they could breach our system without any authorization, and the second part involved using the login credentials we provided to see if a valid user could access data they shouldn’t be able to access.

After we finished the testing, they provided us with recommendations on how we could resolve the issues they identified.

What is the team composition?

We worked with four people from Nexa IT. They were each involved in different aspects of the project.

Nexa IT was recommended to us by a third-party development company that we’ve worked with for a long time.

How much have you invested with them?

We spent $10,000 on this project.

What is the status of this engagement?

We worked with them on this project from August–September 2021.

RESULTS & FEEDBACK

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

Nexa IT identified some minor and significant deficiencies in our app. The good thing is that they were unable to gain access without the login credentials, which was our biggest fear. Overall, we were very pleased with the outcome of this project.

How did Nexa IT perform from a project management standpoint?

Nexa IT performed exceptionally well in terms of project management. They laid out a specific schedule and budget, and they were very good at sticking to it. They also communicated well despite working fully remotely.

What did you find most impressive about them?

I was really impressed with Nexa IT’s credibility, expertise, and professionalism.

Do you have any advice for potential customers?

Make sure to go into the project with a good understanding of the outcomes you’re trying to achieve. Penetration testing is a generic term, so it would be very beneficial for both you and Nexa IT to understand precisely what you’re hoping to accomplish so that they know what services they need to provide.
