Offensive Security (Red Team)
Smaller than most branches in raw headcount, since most companies only need a few offensive specialists (or hire it out entirely), but the specialized end of this branch pays some of the highest rates in the field.

Penetration Tester
Legally breaks into a company's own systems before a real attacker does.
What it's about & how to get in
Companies hire you to legally break into their own systems, networks, applications, sometimes physical offices, before a real attacker does, then hand over a report explaining exactly what you found and how to fix it. Most pentesters work on defined, scoped engagements (a couple of weeks per client) rather than one ongoing job, which is why a lot of this work happens through consulting firms.
The learning curve is steep and mostly hands-on: you need to actually be able to exploit real vulnerabilities, not just describe them, so practical, lab-based certifications carry more weight here than in almost any other branch.
Where you can work
- Penetration testing and offensive security consulting firms — where most pentesting jobs live
- In-house “internal red team” roles at large tech and financial companies
- Bug bounty and vulnerability research programs, often freelance or independent
- Government and defense contractors running authorized penetration tests
- Security product companies validating their own tools against real attack techniques

Web Application Penetration Tester
Specializes in breaking web apps and APIs, where most customer-facing risk actually lives.
What it's about & how to get in
A specialized branch of pentesting focused entirely on web and API applications, finding things like injection flaws, broken authentication, and access-control bugs in the software companies actually ship to customers. It overlaps heavily with bug bounty work: a lot of web app pentesters also hunt on platforms like HackerOne or Bugcrowd on the side, and some go independent full-time once they've built a track record.
Because web apps are where most companies' customer-facing risk actually lives, this specialty pays noticeably more on average than general network pentesting.
Where you can work
- Application security teams inside SaaS and e-commerce companies
- Penetration testing consulting firms with a dedicated AppSec practice
- Bug bounty platforms (HackerOne, Bugcrowd) as an independent or supplemental income stream
- Fintech companies, where application-layer bugs carry outsized financial risk
- Product security teams at software vendors, testing their own releases before ship

Red Team Operator
Simulates a real, patient adversary trying to reach a specific target without getting caught.
What it's about & how to get in
The most advanced and least common role in offensive security: instead of a scoped pentest looking for as many bugs as possible, you're simulating a real, patient, targeted adversary trying to achieve a specific objective (like reaching a company's crown-jewel data) without getting caught by the defensive team.
That means a longer engagement, more emphasis on stealth and evasion than raw exploitation, and close coordination with (or deliberate concealment from) the client's blue team. This is a senior specialization almost nobody starts in — most red team operators spend years as penetration testers first.
Where you can work
- Dedicated red team practices at large enterprises with mature security programs
- Specialized red-team and adversary-simulation consulting firms
- Government and military cyber units running full-scope adversary emulation
- Large tech companies with internal “purple team” programs pairing red and blue teams
