We heard good references about their work.
Describe the project in detail.
UnderDefense security experts followed OWASP Mobile Application Security Verification Standard. Their team closely cooperated with our internal development and security teams. We started with mapping all stages of our engagement divided into a few blocks.
Each day we received updates on detected vulnerabilities. During our weekly retrospectives, we worked on improving our workflow to get maximum results. Also, our project required onsite visits to check the special functionality of QR codes service for our clients.
Most of the work was done remotely and onsite visits were needed to deliver findings to our C-level team and repeatedly check a particular functionality in real-time. The last touchpoint of our involvement was the findings report delivery and working with our internal team by mentoring how to mitigate found gaps.
What was the team composition?
2 pentesters, 4 weeks

The client submitted this review online.
Please describe your company and your position there.
I'm the VP of Engineering at Palo Alto Software, a 100-person software company with multiple SaaS products.
For what projects/services did your company hire UnderDefense?
As part of operating a business email service, we hired UnderDefense to test our application's security. It is important that our customer's data is secure and that our application protects them from malicious behavior. We have some internal security knowledge but knew that we needed an expert team to do a comprehensive evaluation of our software.
What were your goals for this project?
Our primary goal was to establish that our application met baseline security requirements, and to have a clear remediation plan for cases where it didn't.
How did you select this vendor?
UnderDefense discovered a vulnerability in our application and made a responsible disclosure to us. We were already in the market to hire a penetration testing firm, and our positive interaction with UnderDefense along with their competitive pricing helped us to select them.
Describe the project in detail.
The project entailed external perimeter penetration testing and "grey box" web application penetration testing. We had several conference calls to establish the scope of work and outline our internal assets, followed by a three-week evaluation. The result of the project was a detailed report with a general grade of our security status and a list of discovered security vulnerabilities with detailed reproduction steps.
What was the team composition?
UnderDefense provided two security consultants along with project management. I was the only person involved on my side of the project.
Can you share any outcomes from the project that demonstrate progress or success?
We are very pleased with the results of the evaluation. UnderDefense completed a thorough investigation and presented a polished report that was informative and easy to read.
How effective was the workflow between your team and theirs?
Despite being in very different time zones, communication was fairly straight-forward. We mostly communicated via conference call and a shared Slack channel. I was a little nervous about potential language barrier issues, but that was not a problem at all.
What did you find most impressive about this company?
I don't know that there was any one thing that stood out about them. They did quality professional work, at a reasonable price.
Are there any areas for improvement?
They could have provided more progress reports during the evaluation, but given the short duration of the project, it wasn't necessary.

the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the owner and system director of Market Access Direct, a marketing, consulting, and lead generation company. We focus on senior market products such as Medicare supplements or final expense insurance.
What challenge were you trying to address with UnderDefense?
We were trying to address our security. Our CRM’s security requirements needed to reflect the policy-holder data and personally-identifying information (PII) in it. We started looking for cybersecurity help when we realized our existing process was insufficient.
What was the scope of their involvement?
They took us from a shared-server platform to a private AWS infrastructure. They created a roadmap for us, so we knew where our data resided, how it was accessed, and how it was treated and protected. Everything needed to be addressed and put into the roadmap, and we had a very short time to get this done.
One of the invaluable consulting services UnderDefense gave us was walking us through the different areas where we needed security. I had done some research, then they drew us a picture of how we’d access the data, encryption, vulnerabilities, and solution.
What is the team composition?
We worked with 5–6 people from their team.
How did you come to work with UnderDefense?
I went through all the vendors listed on Clutch and got quotes, then Victoria (Cybersecurity Strategic Partnerships & Business Development, UnderDefense) called us that very night to say she would take our project to her CEO. Within three hours, I was contacted by someone who said they could help us. I explained the timeline and highlighted the fact that we couldn’t change it even though it was extremely tight.
Nazar (CEO, UnderDefense) called us the next night. He had a consultative approach and took time to educate us before we picked them. I’m based outside Philadelphia, and he took the time to come to our location, going above and beyond to help our decision. It was comforting, as we were in trouble with our cybersecurity.
How much have you invested with them?
For the first phase, we’re now at $25,000. Going forward, they’re going to reperform penetration vulnerability testing every 4–6 weeks over the next year. There will be a monthly spend of $10,000–$20,000 for the foreseeable future.
What is the status of this engagement?
We started working with UnderDefense in March 2019, and our collaboration is ongoing. Within three weeks, they had the platform up and running.
What evidence can you share that demonstrates the impact of the engagement?
We wouldn’t have passed any testing before, then two and a half weeks in, the vulnerability testing was looking really good, and the penetration testing identified a couple of things to work on. Now, I feel we’re free and clear.
UnderDefense rapidly organized a team that understood the code we were moving and how the system needed to be accessed by multiple users. They acted on the roadmap in such a way to not disturb our workforce, frequently working at night. We threw them some curveballs, and they handled them nicely.
How did UnderDefense perform from a project management standpoint?
I’m very pleased. We normally communicate over phone and email.
What did you find most impressive about them?
UnderDefense is that they became more of a partner than a vendor. We had two other companies tell us that our requirements weren’t acceptable, but UnderDefense put together a problem-solving team that figured it out. Both sets of people—on our side and theirs—did their own research, reconvened, talked through different solutions, and then deployed one. It was quite collaborative.
I’m also now very familiar with what a virtual CIO is. In a very short period of time, UnderDefense explained it to us and put solutions in place. We have a higher standard of actually participating with our clients, in terms of protecting their data.
Are there any areas they could improve?
No. I expected there to be some time-zone or language issues, but there weren’t. Their project manager was in New York, so we had face-to-face brainstorming meetings. I would highly recommend them.
Do you have any advice for future clients of theirs?
It’s easy to make a list of services to buy and think we know best, but this was new territory for me. UnderDefense proposed the best solutions for me and are exactly the kind of partner I’d choose.
