      Software Development Review from Michael Meyer

      We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

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%
