What Do Cybersecurity Companies Do?

Cybersecurity companies provide a range of services to protect organizations from digital threats. This includes Managed Security Service Providers (MSSPs) offering 24/7 SOC monitoring, penetration testing firms that simulate real-world attacks, vulnerability assessment teams that identify weaknesses, and incident response specialists who contain and remediate breaches. Many also offer compliance consulting for frameworks like SOC 2, HIPAA, PCI-DSS, and GDPR.

2

Industry Focus
