  • Review architectures and changes to spot risks before release
  • Test defenses using vulnerability scanning and controlled penetration testing
  • Investigate incidents, contain threats, and support recovery with clear updates
  • Write security standards and help teams follow them in daily work

A day in the life

  1. Check alerts and logs, then triage anything suspicious with the response team
  2. Meet engineers to review a new feature and agree on security requirements
