Digis Reviews & Testimonials

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.

Web Development Review from Alexander Nikolaevsky
We have hired the Plavno team to develop a cryptocurrency exchange solution.allow users to make cryptocurrency transactions legally and transparently. Plavno team had to create a solution independent of third-party developers, develop frontend solutions for clients and service administrators, build a full-featured back-end that would include integration with banking and payment systems, and a multifunction module for managing currency exchange transactions, exchange rates.

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. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

Mobile App Development Review from Lee Tupper
Vention has delivered excellent design prototypes and accurate time estimates. The app is still in beta mode, and the partnership with [...] Vention will [continue] until the release of the next version. Vention is a reliable team that offers quality service. (Verified via email)

Staff Augmentation Review from Jon Wade
Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.

Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

I had given interview in this organization. Interview process was very good and the HRs are helpfull also. Although I have not joined this organization but their leave policy is not good at all. Also the timings are srict as they mention. In other kolkata based companies the no. of leaves are higher.

Cybersecurity Companies FAQs
What services do top cybersecurity companies in the USA provide?
They offer a comprehensive range of services to protect a business from digital threats and attacks. According to IBM’s latest report, businesses are increasing their investments in these top 5 services:
- Threat intelligence and analysis (43%): Gathering data on cyberthreats, adversary behaviors, and emerging vulnerabilities to proactively defend systems
- Data security and protection tools (37%): Implementing firewalls, encryption, and data loss prevention (DLP) solutions to ensure the confidentiality and integrity of a company’s data
- Incident response and testing (35%): Developing and testing a strategy to monitor, identify, and manage threats to minimize business damage
- Security awareness training (33%): Educating employees on the latest security best practices and the company’s security protocols
- Offensive security testing (32%): Employing ethical hacking and penetration testing to simulate real attacks to uncover and address vulnerabilities
What is a typical project implementation timeline for this industry?
Typically, cybersecurity implementation can take a few months to over a year, depending on your current security stature, IT infrastructure, industry-specific regulations, and project scope and complexity.
Here's an approximate cybersecurity timeline:
| Stage | Tasks |
System audit and requirement analysis |
|
System Design |
|
| Policy development (1-2 months) |
|
| System development (4-6 months) |
|
| System Testing (3-4 months) |
|
| Implementation (1-3 months) |
|
How much do businesses allocate for cybersecurity?
Depending on service scope, business size, number of devices, IT infrastructure complexity, and compliance requirements, businesses allocate 5-20% of their IT budget to cybersecurity.
Here’s an approximate breakdown according to business size:
- Small businesses (less than 100 employees) allocate 5-10% of their IT budget for cybersecurity, as they typically cover fewer systems and users.
- Medium-sized companies (100-1,000 employees) invest 8-15% of their tech budget, as they may need more comprehensive endpoint and cloud security services.
- Large enterprises (1,000+ employees) dedicate 10-20% of their technological budget, often requiring 24/7 security operations, full compliance and support audits, and more complex security solutions.
How often should businesses audit their cybersecurity?
Approximately 23% of security breaches stem from IT failure, and 26% are caused by human error — both of which are preventable with regular security audits.
Here’s how often you should conduct cybersecurity audits according to best practices:
- Annual audits for comprehensive audits of your entire system, including your policies, frameworks, network, and recovery plan.
- Biannually and quarterly to achieve regulatory compliance (e.g., PCI DSS and HIPAA), protect highly sensitive data, and manage complex infrastructures. A common practice is to conduct monthly vulnerability assessments and quarterly penetration testing.
- Immediately after a reported incident or a change in your infrastructure (e.g., implementing a new enterprise resource planning system).
What US industries benefit from cybersecurity services?
While all industries benefit from working with top cybersecurity companies, research shows that certain sectors experience more threats than others. Here are the sectors with the most damaging breaches and the share of breaches exceeding $1 million:
- Healthcare: 47%
- Tech, Media, and Telecom: 43%
- Financial: 38%
- Energy, Utilities, and Resources: 37%
- Industrial and Auto: 33%
- Retail and Customer: 28%
