Please describe your company and your position there.
Demio is a hassle-free webinar platform built for marketers. With our platform, companies can generate leads, filter prospects, perform group demos, host engaging sales presentations, integrate with their CRM, view advanced webinar reporting, track conversions, and more.
It’s truly unlike any other product on the market. I am one of the co-founders here at Demio and help run the operations and general administrative functions.
For what projects/services did your company hire Berezha Security Group?
Demio is always looking to improve and we've put a big emphasis on the security/privacy aspect of our engineering in 2020. We ended the year with a full-service penetration test to find any weak points in our architecture. We searched for a quality penetration testing company and found Berezha Security Group as a highly rated company, already recommended.
What were your goals for this project?
Our goal was to have a full breakdown of any security or privacy issues within our SaaS architecture. We are always looking for ways to operationally improve, but in this instance, we wanted to find any technical items we may have missed. This serves to provide a safer experience for our customers, reduce risks to the company, and make it easier to scale.
How did you select Berezha Security Group?
One of our Senior engineers recommended a list of certified vendors and on this list was the highly-rated Berezha Security Group. The Demio Director of Engineering lives in Ukraine and was in the same city/timezone as Berezha. This made communication a breeze and perfectly synced timezones.
Describe the project in detail.
Once we reached out, the Berezha Security Group worked with us on a timeline and project scope for the project. We had a shorter timeline and they were generous enough to find a way to get a schedule for work through the end of the year and on our timeline.
They joined the Demio Slack group and aligned with our Engineering team to walk through the Demio application and architecture. They were able to view both the user experience and gained access to an account using a non-production environment. After the penetration testing, we spent time on a call to review the report and individually view/diagnose any problems that were found.
They work to outline risks by different categories and are realistic in both the business and privacy concerns each one holds. You can then run a re-test when we complete the findings.
What was the team composition?
We spoke and worked with the CEO/Founders to set up the project and had a project manager and security engineers inside of the Demio team. The project flowed smoothly with communication and calls.
Can you share any outcomes from the project that demonstrate progress or success?
With the help of Berezha, we've diagnosed all pending issues on our production servers and closed 50% within the first week. We've then used their risk categories to outline new changes for the future, based on priority in our current roadmap.
How effective was the workflow between your team and theirs?
Our workflow was very smooth. The fact that both our Director of Engineering and the Berezha team were in the same city made the timezones work out perfectly. English was perfectly communicated and the report/findings were extremely thorough.
What did you find most impressive about this company?
Just how helpful they have been through the process. They were there to guide us through each step of the penetration test and understand the business use case almost immediately. This made getting the results a breeze.
Are there any areas for improvement?
We felt that Berezha firmly upheld their promises and delivered the test on time, on budget, and with great communications. We look forward to working with them more in the future.

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.
We’re a health company that serves doctors and patients in managing medication. I’m the CEO.
What challenge were you trying to address with Berezha Security Group?
We hired them to handle penetration testing following a software development project our company completed.
What was the scope of their involvement?
They were responsible for testing two web apps as well as our native apps. Working remotely, they provided a set of testing credentials for both doctor and patient users. Their job was to use as many techniques as possible to attempt to compromise the system.
What is the team composition?
We worked with about four people, including a business representative, a senior software engineer, and two junior software engineers.
How did you come to work with Berezha Security Group?
I found them on Clutch, which was quite useful in my search. We found that their services were in our price range and ranked toward the top of the page. Our team reached out to the top 4–5 vendors on the site, and they were highly engaged. They also offered a very reasonable price, so we hired them.
How much have you invested with them?
We spent about $10,000 on the work.
What is the status of this engagement?
We worked together from November–December 2020.
What evidence can you share that demonstrates the impact of the engagement?
They produced an extensive report detailing their findings and recommendations. Once our team implemented their recommendations, they provided a follow-up testing. To verify the robustness of their work, we had an external coder look at the product. They confirmed that they approached the penetration test using best practices and were quite thorough in their work.
How did Berezha Security Group perform from a project management standpoint?
Their communication was excellent, and they did very well with deadlines. We had a situation that required us to move very quickly on our end. They ramped up speed along with us, working around the clock and on weekends, to help get things done.
What did you find most impressive about them?
They were extremely upfront and transparent with us. I appreciated that they communicated recommendations in a clear, straightforward way. They even helped some of our developers in the process. It was great to have a partner that was completely transparent about what we could expect from them and what they could not do. Most vendors want to sell the dream rather than the reality, so their honesty was appreciated.
Are there any areas they could improve?
I think they’re doing a fairly excellent job with what they’re doing. I’d love to see their business expand into other areas such as reviewing general compliance standards.
Do you have any advice for potential customers?
Have your software engineers primed and ready to be completely responsive to their team. Sometimes, their team will identify critical vulnerabilities that need to be fixed instantly. Ensure your team is prepared and not feeling at all threatened by the presence of a penetration testing team.
