We have been working with the team at Exinent, and they pass with flying colors. They have been responsive to issues that typically develop during the life of an e-commerce platform. They supervised a major upgrade without a serious hitch, which is almost impossible. We highly recommend them.

It has been a pleasure working with Exinent, they are very professional and easy to work with. Every issue or problem I had they always solved it and in a timely manner. Their ticketing system works great and they are pretty fast to address things especially when I have emergencies. Highly recommend them if you are looking for a group of experienced developers.

From start to finish, they work and deliver above and beyond, exceeding my expectations. I highly recommend Exinent for any project. Thank you for your expertise and excellent service

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:
