OSWE (WEB-300) is Offensive Security’s white-box web application security certification — the deepest-paid AppSec credential in Mumbai’s fintech and BFSI markets. PhonePe, Razorpay, BharatPe, CRED, foreign-bank Mumbai application-security teams (JPMorgan, Goldman Sachs), and Indian banks with mature AppSec functions (HDFC, ICICI) hire OSWE-certified engineers into INR 22–35 LPA roles. This page covers Macksofy’s 12-week mentored OSWE bootcamp delivered as live online cohorts and as classroom batches at our Bandra Kurla Complex (BKC) center.
Course Overview — OSWE (WEB-300) in Mumbai
Mumbai is India’s financial capital — banks, capital-market infrastructure, insurance, fintech and media — the densest concentration of regulated-industry security hiring in the country. OSWE is the benchmark white-box web-exploitation certification — proof you can read source code and chain real application vulnerabilities into working exploits — the exact skill these AppSec and product-security teams struggle to hire. OSWE (WEB-300) is awarded by OffSec after a 48-hour practical exam; Macksofy delivers it as an independent exam-prep bootcamp with source-code-review labs and Mumbai-context case studies for application-security engineers, web pentesters and bug-bounty hunters.
Macksofy is not an Offensive Security Authorized Training Partner; this is an independent mentor-led prep program for the OffSec certification exam.
Why Mumbai cybersecurity professionals need OSWE
Mumbai’s payments and fintech sector — PhonePe, Razorpay, BharatPe, CRED, Pine Labs, Slice, plus the lending fintech wave — treats OSWE as the gold standard for hiring senior AppSec engineers. The cert validates source-code review skills against complex authentication flows, deserialization, blind injection, and chained exploit scenarios that black-box pentest certs (OSCP, CEH) don’t cover at the same depth.
BFSI Mumbai also hires OSWE for source-code-review compliance work driven by the RBI Master Direction’s secure-SDLC expectations and SEBI CSCRF’s third-party application security review requirements. Banks running internal AppSec teams (HDFC, ICICI, Kotak) plus Big 4 cyber Mumbai practices need OSWE-skilled reviewers for regulated application security audits.
OSWE is harder than OSCP from a code-reading perspective: the 48-hour exam requires writing a working exploit chain against custom application source code, often involving multiple bypasses and a final unauthenticated RCE. Pass rate globally is around 25%; Macksofy alumni achieve significantly higher first-attempt pass through mentored code-review practice, weekly white-box challenges, and instructor-supervised mock exams.
For candidates already holding OSCP, OSWE is the most logical next OffSec step into the AppSec specialization — and it commands a 50–80% salary premium over OSCP-only at the same experience level for Mumbai fintech and foreign-bank AppSec roles. Combined with cloud-security certifications (AWS Security Specialty, Azure Security Engineer), OSWE-holders unlock product security engineering tracks at Mumbai unicorns.
OSWE (WEB-300) Curriculum for Mumbai Cohorts
Mumbai cohorts map the OSWE syllabus onto the BFSI, capital-markets and fintech work local teams do. The full WEB-300 syllabus — source-code review, authentication and access-control bypasses, injection and deserialisation, and building chained exploits — is identical in every Macksofy Mumbai cohort and maintained on our OSWE (WEB-300) course page, so the Mumbai schedule always reflects OffSec’s current exam.

Frequently Asked Questions — OSWE Training in Mumbai
Is OSWE worth it after OSCP for a Mumbai fintech AppSec career?
Yes — for Mumbai fintech (PhonePe, Razorpay, BharatPe, CRED, Slice) and BFSI AppSec roles (HDFC / ICICI internal AppSec, foreign banks), OSWE adds a clear 50–80% salary premium over OSCP-only at the same experience level. The cert specifically validates white-box code-review skills that black-box pentest certs don’t cover.
How much does OSWE training cost in Mumbai?
The Macksofy OSWE bootcamp is INR 95,000 for the online live cohort and INR 117,000 for the classroom-tier batch for Mumbai learners. Pricing is exclusive of the OffSec OSWE exam fee (USD 1,749, paid directly to Offensive Security, includes a 90-day lab subscription). EMI is available across HDFC / ICICI / Axis / SBI / Kotak cards — confirm current figures at enrolment.
Do I need OSCP before attempting OSWE?
OSCP is not a formal prerequisite — OffSec doesn’t enforce it — but for Mumbai candidates we recommend it (or a strong dev / source-code-review background) first, since WEB-300 assumes comfort with HTTP, web payloads and exploitation flow. About 80% of Macksofy OSWE candidates also hold OSCP.
How is OSWE different from OSCP?
OSCP is black-box penetration testing (find a way in given an IP and goal); OSWE is white-box application security (find a way in given the source code). Mumbai OSWE candidates spend far more time reading framework code (Java Spring, Node.js, Django/Flask, .NET) and writing Python exploit scripts, and the OSWE exam is 48 hours versus OSCP’s 24.
Which Mumbai fintech and BFSI employers actively hire OSWE-certified engineers?
Mumbai-active OSWE hirers: PhonePe, Razorpay, BharatPe, CRED, Pine Labs, Slice (fintech); JPMorgan / Goldman Sachs / Morgan Stanley Mumbai (foreign-bank AppSec); HDFC / ICICI / Kotak (Indian-bank internal AppSec); Big 4 cyber Mumbai practice; NSEIT / Lucideus / Sequretek (Mumbai MSSPs running BFSI source-code reviews). Salary band 22–35 LPA at 4–7 years post-OSWE.
Can I take Macksofy OSWE training online while based in Mumbai?
Yes — our live online OSWE cohort is designed for working Mumbai AppSec engineers, with evening + Saturday sessions and Mumbai-time-zone-aligned mentor office hours. The classroom batch at BKC is suited to full-time learners or candidates on focused study leave.
Does Macksofy offer EMI for the OSWE bootcamp fee?
Yes — for Mumbai learners we offer 0% EMI across major Indian credit cards (HDFC, ICICI, Axis, SBI, Kotak) over 3, 6 or 9 months; the classroom-tier batch at INR 117,000 works out to roughly INR 13,000/month on a 9-month plan.
What if I fail the OSWE exam after Macksofy training?
Macksofy provides 90 days of post-cohort mentor support including additional mock exams and code-review labs. If you fail the live OSWE attempt, our trainers analyze the failure with you (where the code review broke down, which exploit chain didn’t materialize), then design a focused 4–6 week remediation track at no additional fee before your second attempt.
