Questions

Can a foreigner apply for these roles?

1,348 of the 1,402 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?

Arctic Wolf (24), Work Street (15), Chainguard (11), Alice (11), Upwind Security (11).

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.
