What is OSCE3? OSCE3 (OffSec Certified Expert 3) is an expert-level designation awarded to anyone holding all three advanced OffSec certifications — OSEP (PEN-300), OSWE (WEB-300) and OSED (EXP-301). There is no combined exam; you earn each separately. Macksofy delivers all three in Dubai at AED 5,550 each.
OSCP proves you can break into machines. OSCE3 proves you can do it across three entirely different disciplines — evading enterprise defences, exploiting web applications at source-code level, and writing your own exploits from scratch. It is OffSec’s expert-level designation, and it is one of the rarest credentials in the UAE offensive-security market precisely because it cannot be crammed. This guide explains what OSCE3 is, how the three components fit together, and how to plan the route realistically from Dubai in 2026.
What OSCE3 actually is
OSCE3 stands for OffSec Certified Expert 3. Crucially, it is a designation rather than an exam — there is no OSCE3 course to enrol in and no single test to sit. You earn it automatically by holding all three of OffSec’s advanced certifications at the same time. Each of those three is validated by its own multi-hour hands-on practical exam, so OSCE3 is best understood as recognition of a body of work: three separate specialisms, each proven under exam conditions.
The three components
OSEP (PEN-300) — evasion and Active Directory
OSEP focuses on operating inside defended environments: bypassing antivirus and application controls, advanced Active Directory attacks, lateral movement and staying below detection thresholds. It is the natural next step after OSCP and the component most directly aligned with red-team work in mature UAE enterprises.
OSWE (WEB-300) — advanced web exploitation
OSWE is the white-box web certification. Rather than probing an application from outside, you read its source code, identify vulnerabilities and chain them into reliable exploits. It suits people with development or application-security backgrounds and is highly relevant given how much of the UAE’s banking and government service delivery runs on web applications.
OSED (EXP-301) — Windows exploit development
OSED covers Windows user-mode exploit development: reverse engineering binaries, discovering memory-corruption vulnerabilities, and writing exploits that defeat DEP and ASLR. For most candidates this is the hardest of the three, because it demands assembly, C and debugger fluency that the other two do not.

What order should you take them in?
There is no mandated sequence, but experience suggests a practical one. Start with the component closest to your existing day job, because momentum matters over a multi-year effort: a network pentester should begin with OSEP, while a developer or appsec engineer will find OSWE far more approachable. Leave OSED until last unless you already have a reverse-engineering background — it is the component where people most often stall, and attempting it first can turn a long project into an abandoned one.
Be realistic about the timeline. Each certification represents months of lab work on top of a full-time job, and the three together typically take one to three years. Treating OSCE3 as a two-year programme with clear checkpoints is far more likely to succeed than treating it as a sprint.
Prerequisites and honest expectations
- OSCP first: not formally required, but all three components assume that level of methodology.
- Real engagement experience: lab skill alone rarely carries you through three expert exams.
- Scripting fluency: Python and PowerShell across all three, plus C and assembly for OSED.
- Sustained lab time: plan for consistent weekly hours rather than intensive bursts.
- A specialism to lead with: start where you are already strongest, then broaden.
Is OSCE3 worth it in the UAE?
For the right profile, it is one of the strongest signals available. The UAE offensive-security market has grown quickly, and OSCP is now common enough that it no longer differentiates senior candidates on its own. OSCE3 does, because it demonstrates depth in three directions at once — and because the number of regional holders remains very small. The roles it opens are principal or lead-level: red-team leadership, specialist consultancy, vulnerability research and internal offensive-security functions at banks, telecoms and government-linked entities.
It is not, however, the right goal for everyone. If your career is heading toward SOC leadership, governance or compliance work under NESA or ADHICS, defensive and management credentials will serve you better. OSCE3 rewards people who genuinely want to stay deeply technical for the long term.
Macksofy Technologies delivers all three OSCE3 component courses — OSEP (PEN-300), OSWE (WEB-300) and OSED (EXP-301) — in Dubai as hands-on, instructor-led bootcamps, so you can work through the path locally with structured guidance rather than entirely self-taught.
Frequently Asked Questions
What is the OSCE3 certification?
OSCE3 — OffSec Certified Expert 3 — is not a separate exam. It is an expert-level designation awarded to professionals who hold all three of OffSec’s advanced certifications: OSEP (PEN-300), OSWE (WEB-300) and OSED (EXP-301). Because each is validated by its own demanding practical exam, OSCE3 signals proven capability across evasion, web exploitation and exploit development.
How do you earn OSCE3?
You earn it by passing the three underlying certifications individually — there is no combined exam and no shortcut. Most candidates complete them one at a time over a period of one to three years, usually starting with OSEP or OSWE and finishing with OSED, which is the most technically demanding for people without a reverse-engineering background.
Is OSCE3 harder than OSCP?
Considerably. OSCP is the core offensive benchmark and a prerequisite in practice for all three OSCE3 components. Each OSCE3 certification assumes OSCP-level skill as a starting point and then goes deep into a specialism. Holding all three represents years of hands-on work rather than a single exam effort.
Is OSCE3 worth pursuing in the UAE?
For senior offensive-security professionals, yes. UAE banks, government entities, telecoms and MSSPs are building mature red teams and specialist testing functions, and very few regional candidates hold all three certifications. That scarcity makes OSCE3 a strong differentiator for principal pentester, red-team lead and vulnerability-research roles in Dubai and Abu Dhabi.
How much does OSCE3 training cost in Dubai?
At Macksofy Technologies in Dubai, each of the three components — OSEP (PEN-300), OSWE (WEB-300) and OSED (EXP-301) — is priced at AED 5,550 for instructor-led exam-preparation training. The official exams are administered by OffSec — confirm current exam details and fees directly with the vendor.
Disclaimer: OSED (EXP-301), OSEE (EXP-401), OSMR (EXP-312), OSEP (PEN-300), OSWE (WEB-300) and OSCP (PEN-200) are certifications awarded by OffSec. Macksofy Technologies delivers independent, hands-on exam-preparation bootcamps and is not affiliated with or endorsed by OffSec. CEH, CHFI, CPENT and CTIA are EC-Council certifications (Macksofy is an EC-Council Accredited Training Center). Course modules, exam formats and fees can change — confirm current details with the respective vendors.
