A cybersecurity company is an organization or business entity that specializes in providing products, services, and expertise aimed at protecting digital systems, networks, data, and information from a wide range of cyber threats and vulnerabilities. These threats can include malware, viruses, ransomware, phishing attacks, data breaches, insider threats, and more.

The primary goal of a cybersecurity company is to help individuals, businesses, government agencies, and other entities establish robust and effective security measures to safeguard their digital assets and infrastructure. This often involves the development and deployment of security solutions, such as antivirus software, firewall systems, intrusion detection systems, encryption tools, and security consulting services. 

Cybersecurity companies may also offer services like threat intelligence analysis, incident response, security audits, penetration testing, and ongoing monitoring to identify and mitigate security risks.
