To provide you with only the top cybersecurity companies in the USA, our 12 veteran experts have extensively vetted each listing using our five main ranking criteria. We have also vetted over 800 of their client reviews to equip you with a well-researched, unbiased assessment of each provider’s capabilities.

Organic rankings are determined by five factors: top services, reviews, portfolio, awards/press, and team expertise. Sponsored listings pay for a placement that appears above organic positions. Sponsorship does not affect star ratings or review content - read more on our methodology page.

    • Taras Oliinyk
      Taras Oliinyk СEO at U1CORE
      5.0★

      IT Services Review from Taras Oliinyk

      The project involved developing a mobile app for an e-commerce client, with U1CORE building the marketplace and WEZOM responsible for the mobile application. Both companies worked as partners on the same product, so the mobile app had to fit naturally into the marketplace's functionality. WEZOM brought solid mobile development expertise to the project and built the application around the marketplace requirements. Their team was able to work within the shared product setup and keep the mobile functionality consistent as the project progressed. We would be happy to work with WEZOM again on similar projects!

      eCommerce Development Review from Ivan Usenko

      We involved WEZOM to support the technical side of a U.S. e-commerce client's advertising setup. Our team handled PPC and marketing, while WEZOM implemented server-side tracking and profit-based ROAS attribution.Their technical work fit well into the client's existing setup and gave us a more reliable view of campaign performance. This made it easier to assess results and adjust advertising spend accordingly. Overall, we had a positive experience with WEZOM!

      eCommerce Development Review from Max Zakhozhiy

      For one of our jewelry e-commerce clients, WEZOM took care of the website development while our team handled its promotion. The teams coordinated well throughout the project, especially on technical requirements that could affect the websites future promotion. WEZOM was open to our input and made it easy to align development with the client's marketing needs. The finished website gave us a good foundation for ongoing promotion, and we were happy with how the two teams worked together. We'd be glad to collaborate with WEZOM again.

      Software Development Review from Claus-Peter Mueller

      We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

      Syberry is the best! I can't even find the words to express how happy I am with my experience. This was the first time my company created a customized program, so I was initially very hesitant and apprehensive about the project. Syberry helped us transform a very lengthy and involved Excel sheet containing a large volume of important and sensitive information into a program that streamlined a complex process into a highly efficient system. Rudy was my main point of contact, and he was with me every step of the way. I can't say enough good things about the team we worked with to develop the program. By the end of the project, it was very sad to see them go. We looked forward to our weekly meetings with our dedicated Syberry team. I already have plans to start another project with Syberry and am looking forward to it! Thank you again, Syberry Team! You are all the best!

      We've done multiple projects with Syberry and found them to be professional and effective. They utilize current development methodologies and have solid project management. They were able to deliver timely work and stay within budget - areas where other offshore firms I've used struggle. I highly recommend them for any of your future technical projects.

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 
(1 month) 

  • Identifying business needs and high-priority system issues 
  • Developing a cybersecurity roadmap 

System Design 
(1-3 months) 

  • Crafting system architecture and an integration plan
Policy development 
(1-2 months) 
  • Establishing security policies, procedures, and frameworks
System development 
(4-6 months) 
  • Configuring cybersecurity solutions, such as firewalls and encryption tools 
System Testing 
(3-4 months) 
  • Conducting penetration, regression, and other quality tests to ensure system reliability and usability 
Implementation
(1-3 months) 
  • Ensuring the cybersecurity system’s deployment readiness and transferring it to a live environment 
  • Conducting employee and stakeholder training 

 

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%
