• Technical Support: IT support services come in different forms, depending on the needs of the business: 
  • IT Helpdesk Support: Provides basic troubleshooting and assistance for everyday software or hardware issues. For example, employees may contact the helpdesk for help with password resets or system errors.
  • Managed IT Services: Involves outsourced management of IT functions, including monitoring and maintaining IT systems, ensuring businesses run smoothly without dedicated in-house resources.
  • Enterprise IT Support: Tailored for larger organizations with complex IT environments, this service covers everything from strategic IT planning to system integration, supporting sophisticated infrastructure and enterprise-level applications.
• Cybersecurity: IT services help safeguard businesses against cyber threats through various security measures. These include penetration testing, which simulates attacks to identify vulnerabilities, and risk assessment services, which analyze potential threats and recommend strategies to mitigate risks. 
  • Additionally, companies invest in security services like firewalls, intrusion detection systems, and regular security audits to protect sensitive data and prevent breaches.
• Compute Services: Provides on-demand computing power through cloud solutions. Rather than focusing only on major providers like AWS and Microsoft Azure, businesses increasingly adopt hybrid cloud approaches, combining private and public cloud solutions. This gives them greater control over sensitive data while enjoying the scalability and flexibility of public cloud resources. 
  • A hybrid model allows businesses to run mission-critical applications on private clouds while leveraging public cloud services for less sensitive workloads, optimizing costs and performance.
