Questions

Can a foreigner apply for these roles?

80 of the 80 roles here state no citizenship or security-clearance demand. A role that does says so in its advert, and the card marks it.

Which companies hire most cybersecurity specialists?

Toss (24), Coupang (12), ENKI WhiteHat (8), Kurly (4), KONA I (2).

Which roles count as cybersecurity jobs?

Every role whose work is protecting systems and data - SOC and incident response, threat intelligence and forensics, application and cloud security, authorized penetration testing and vulnerability management, identity and access, governance, risk and compliance, security leadership - at any employer. A role is filed under a specialty when its title names one; a "Cybersecurity Engineer" that names none is a cybersecurity engineer's.

How fresh is this?

Every role is re-checked on the employer's own careers board at least every 48 hours, and the page is rebuilt every night.
