UI/UX Design Review from Wladimir Wolinski
Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions.We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it.We were basically satisfied with everything.
Website Redesign Review from Michael Wilson
Digis is redesigning our website to a magento based platform to migrate from a Wordpress based platform. Key deliverables include a full discovery document to determine and outline the scope of the work and the magento platform with custom development to fit our needs.Everything has been delivered on time. Danila our project manager has great communication and always responds in a timely manor. We always receive clear explanations and detailed time logs for the work that is done.
Mobile App Development Review from Gina Levy
Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems. Previously, we had many complaints in the app store. Since working with this developer and tester, these complaints about the app functioning and bugs have disappeared.The time zone different is sometimes challenging, since we are in California and they are in Europe.

Financial Review from Mitya Smusin
Some problems can only be solved with code, but others require end-user thinking. So Plavno developers remember that the whole goal is to solve problems — not only to write code. They thought about the problem from the restaurantants point of view.They developed a food delivery app with both customer and admim panels, which covers all the necessary functionality.
IT Outsourcing Review from Yana Romanovskaya
Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit.

Staff Augmentation Review from Dzmitry Novikau
I worked with Kernelics on a crypto project where we needed help with both design and development. From the beginning, the team was easy to communicate with and clearly understood what we were trying to build.The designer improved our initial ideas by making the user experience more intuitive. They suggested better ways to structure the navigation and user flow, which helped reduce friction and made the product easier to use.We also brought in one of their developers, who worked alongside our existing team member. They collaborated well, completed the work on time, and handled some challenging parts of the exchange functionality without any issues.Overall, Kernelics delivered quality work, stayed within budget, and were professional throughout the process. I’d recommend them to others looking for a reliable design and development partner, especially for crypto or fintech projects.
Web Development Review from Stsiapan Kolesau
I CEO at the construction company specializing in modular buildings and their components. With years of experience and multiple projects, we decided to expand our online presence beyond our two existing landing pages. We needed a corporate portal to showcase products, manage content easily, and dynamically calculate product costs.On a recommendation, we chose Kernelics, and their organized approach and clear task division impressed us from the start. They began with an in-depth analysis of our needs and a competitive review. For the design, we requested a minimalist style, and the results were spot on, requiring only minor tweaks to meet our expectations.For development, Kernelics selected React, Next.js, and TypeScript, with Strapi for the admin panel. They also integrated Google Sheets to handle dynamic price calculations, enabling instant updates on the site by simply modifying the spreadsheeta feature weve found incredibly useful.Now, two years later, the portal continues to support our growth, and were planning new developments for our main site.Kernelics stood out for their transparent approach and professionalism at every stage, and I confidently recommend them to anyone seeking a reliable web development partner.

Staff Augmentation Review from Sergey Novik
Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.
Web Development Review from Domien Van Eynde
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality.

Penetration testing companies perform ethical cybersecurity tests designed and built to identify and carefully exploit vulnerabilities impacting a certain organization's computer systems, networks, websites, and applications.
Pen testing companies intentionally launch a series of simulated cyberattacks, a form of ethical hacking, while utilizing strategies, methodologies, and tools formulated and created to gain access to IT systems and networks.
A penetration testing firm executes this process to uncover weak points and risks so they can be addressed immediately, significantly lowering the odds of getting targeted and harmed by malicious attacks.
Weak areas in the defenses of systems and networks may cause easy exposure to threats or data and overall security breach. Pen testing firms detect these exploitable issues and spot other susceptibilities.
Here are what a penetration testing service provider can do for your company or business:
Penetration testing companies perform deliberate attempts at breaching application systems such as application protocol interfaces or APIs and frontend and backend servers. This procedure will reveal vulnerable input that may be prone to attacks and code injection by hackers.
A penetration testing firm can deliver valuable insights and assessments following the results of the pen tests. Using these observations, the penetration test team can finetune your web application firewall or WAF, making adjustments, modifications, and tweaks where necessary.
Pen testing companies meticulously examine and evaluate computer systems and networks level and depth of security. Using the same techniques, processes, and tools that attackers use, pen testing experts discover and demonstrate what impact and damage system and network weaknesses can have on your business.
In this light, your penetration testing service provider can give you data-driven and well-calculated recommendations for more robust and powerful security policies and strategies.
These are the five phases that complete the whole cycle of a pen test:
This is when your penetration testing firm defines the test's scope and goal. It includes identifying and locating the systems that need to be addressed and the most appropriate method.
During this stage, your penetration testing service provider will gather as much information as possible such as mail server, and network, and domain names. This information will help them better understand the vulnerabilities of potential targeted applications of threats or attacks.
Next up, the pen test team will evaluate how a specific target may respond to different intrusions and attempts of interruption.
Scanning can be done either through static analysis or dynamic analysis. On the one hand, static analysis allows for the inspection of a target application’s code to estimate how it behaves while it’s running. On the other hand, the dynamic analysis provides real-time evaluation of the overall performance of a target application in its running state, making it the more practical choice for the scanning process.
This stage involves using web application attacks like cross-site scripting, SQL injection, and backdoors to expose the target application’s weaknesses. What pen-testing firms do is try exploiting these vulnerabilities. They will attempt to steal data, escalate privileges, and intercept traffic.
The results of this intentional infringement and disruption will then give them information about the repercussions these may trigger and the extent of potential damages that may be inflicted.
The objective of maintaining an exploit is to determine if the affected vulnerability may turn into a long-term, advanced threat in the system.
This stage will help penetration testing companies more carefully gauge how deeply an attacker could reach if the persistent threat stays in the exploited system. It will also answer the question of how long it would take to detect a lingering threat and its potential to steal sensitive and confidential company data.
The final step comprises the compilation of results and reports following the first four stages. The review and analysis aim to detail the following:
Penetration testing companies must have extensive know-how and capabilities to execute and complete each of the following types of penetration testing:
In an external penetration test, pen testing companies target external-facing assets of your business. These technologies are visible on the internet, such as company websites, web applications, email and domain name servers (DNS), and external network servers.
In some scenarios, there is no need for the penetration testing service provider to be physically present in office. Their security personnel and ethical hackers will conduct the attack remotely from another location.
During an internal pen test, the security tester simulates an attack toward vulnerabilities from behind the firewall. This intends to mimic an intrusion from the inside of the company, whether it is a malicious insider or an employee with compromised credentials that have actual hackers.
A blind penetration test is also called closed-box pen text or single-blind test. In this case, pen testing firms are only provided with no more than the target company’s name. It aims to give a real-time glimpse into how an application attack and a system breach occur.
The double-blind pen test is also known as the covert pen test. During this testing, almost no one within your organization knows that a penetration test is happening. In most situations, not even your in-house IT specialists or security professionals, responding to the impending system assault simulation, are made aware of the pen test.
The covert or double-blind pen tester especially requires a thoroughly detailed scope of the ethical hack in written form to ensure there is no disregard for legal policies and no law is violated.
Beyond its function as a vulnerability scan and a compliance audit, penetration tests are designed for in-depth examination of the effectiveness and efficiency of security controls and protocols in real use by real enterprises in real situations. It is through pen tests that the capacities and preparedness of an organization are measured.
These tests are so valuable in that they can answer whether your company can tackle multiple simultaneous attacks. That is why you will need the expertise of skilled, ethical hackers from a dedicated penetration testing firm.
Pen testing companies can bring light to vulnerabilities early on. Recognizing applications and other aspects of your company’s IT systems and networks that are susceptible keeps you on the lookout and positions you several steps ahead of a would-be intruder. Hiring the services of a penetration testing firm is practical and strategic.
A penetration test is a precautionary measure, too. Through the proficiencies of a pen testing company, you can unveil and measure the readiness and effectiveness of your intrusion detection programs and defenses. Penetration testers will know if your security and protection tools are robust enough and working correctly.
The detrimental effects of an attack include disruption of business processes, financial losses, damaged brand reputation, dissemination of critical and classified data, and interference in the organizational infrastructure.
In the United States alone, the average data breach cost in 2021 was $4.24 million, and the amount continues to rise annually.
Identifying these impacts following a breach allows your company to map out actionable steps to mitigate them, if not entirely avert them.
Several variables influence the asking fees of pen testing firms. These include the complexity of the tests, the choice of or required methodology, and the experience of the agency in the industry.
A pen testing company will also factor in whether the test will be performed on one application or whether there will be multiple tests for various applications. On-site visits mean additional charges, too.
On average though, an excellent-quality, professional penetration testing costs between $15,000 and $30,000. The price for a “simple” pen testing for a single app can start from $5,000.
Here are the qualifications to look for when choosing the best penetration testing agency partner for your business:
Make sure you work with a pen test firm with industry certifications. This guarantees that the agency is a leader and authority in the industry and is equipped with expertise in specific business models. Here are some of the most prominent certifications penetration testing companies can obtain:
Your ideal penetration testing service provider must excel on the job and keep you in the loop of the entire testing process. Its team should inform and provide you with updates during each step of the testing procedures. It is their responsibility to give you adequate explanation and clarification regarding technicalities and other details which may not be clear to you.
Complete transparency in payment structure and payment plans is also a must from the start of the transaction up to the project completion.
Partner with a firm whose testing methods are adaptable to your organizational structure and business model. Your agency choice must also be willing to adjust to your preferred schedule.
In any business or organization, the security of networks, data, and its people is a foremost priority. Investing in a reputable and vastly experienced penetration testing firm is genuinely worthwhile.
You will gain more from investing in prevention and defenses against malicious intruders. In addition to securing finances and crucial information, the benefits of working with a penetration testing service provider entail a specific capacity of freedom and give you your share of peace of mind.
Best of luck!
