Working in this sector

Practice with local teaching systems, public guidance, and synthetic records; access to real systems, evidence collection, security testing, operational changes, and sensitive information requires explicit authorization and appropriate professional handling.

Skills that make the work valuable

  • Application threat modeling
  • Secure code review
  • Security test interpretation
  • Remediation verification

Build proof, not just a list

Review a local teaching application with public security guidance and fictional data. Document one weakness, a proposed fix, and a test that verifies the intended improvement.

How to price this work as a freelancer

Define authorized applications, review depth, test boundaries, evidence deliverables, and retest rounds before quoting security work. Agree the inputs, deliverable, review rounds, and acceptance criteria before quoting. Include preparation, specialist review, equipment or licensing costs, and handover time where relevant. Price ongoing support separately from the initial engagement.

Start with the income you need to replace

Required hourly rate = (target salary + benefits budget + annual business expenses) ÷ (annual billable hours × share of revenue retained after fees).

For illustration, $100/hour × 25 billable hours/week × 48 working weeks = $120,000 revenue. After $20,000 in business expenses, that leaves $100,000 profit before personal taxes. Replacing a $100,000 salary plus $15,000 in benefits under those assumptions takes $112.50/hour, with no percentage fees.

These are editable planning assumptions, not rates surveyed for application security engineer work. Your personal taxes, location, contract terms, and workload still affect the comparison.
