ExploreAbout this exam
The OffSec Certified Professional (OSCP) is a hands-on penetration testing credential awarded by OffSec and associated with the PEN-200 course, "Penetration Testing with Kali Linux." OffSec publicly describes itself as the creator of Kali Linux and describes OSCP as "the gold standard in penetration testing certifications" - a marketing claim made by the vendor, not an independent ranking. Unlike multiple-choice certifications, the OSCP assessment is practical: candidates attack machines in a live lab environment and must submit a professional report documenting their findings, so both technical execution and written communication are evaluated. The skills tested span the PEN-200 syllabus - enumeration and information gathering, vulnerability scanning and analysis, web application and client-side attacks, exploitation and password attacks, Linux and Windows privilege escalation, port redirection and pivoting, and Active Directory attack paths with post-exploitation. Preparation is lab-driven rather than reading-driven: work through the course material, then spend the majority of your time in the labs building an independent methodology, taking structured notes on every host, and practicing report writing before exam day. Note that the official OSCP page was unreachable at the time of writing, so exam logistics could not be verified here - confirm all parameters directly with OffSec before booking.
What you'll study
About OSCP preparation
What is the OSCP exam format?
It is a practical, hands-on assessment carried out in a live virtual lab rather than a multiple-choice test. You compromise target machines, then submit a report documenting your attack paths, evidence, and remediation notes. OffSec also describes the PEN-200 course as the associated training. Because the official certification page could not be retrieved, verify the current machine count, duration, and scoring rules with OffSec before scheduling.
How long is the exam and what is the passing score?
These values could not be confirmed from the official source, which returned a 404 error at the time of writing. Do not rely on figures quoted in forums or older blog posts, since OffSec has changed scoring before. The support portal lists an article titled "OSCP+ Equated Scaled Scoring FAQ" under the PEN-200 section, indicating a scoring change exists, but the details were not retrievable.
How much does the OSCP cost?
The standalone exam fee was not verifiable. OffSec does advertise a Learn One subscription at "$2,749/year*" that "Includes one year of access to one 200 or 300-level course, the associated labs, and two exam attempts." That is a bundled training-and-exam price, not the exam-only fee, so treat it as a training budget figure rather than the cost of a single attempt.
How hard is the OSCP, and what causes most failures?
The common failure modes are not exotic exploits but weak fundamentals: incomplete enumeration, tunnel vision on one host, no reliable privilege escalation checklist, and poor time management under pressure. Candidates also fail on documentation - failing to capture proof, screenshots, and commands as they go, then being unable to reconstruct a valid report. Building repeatable methodology and note-taking habits in the labs addresses most of these.
What should my study order look like?
Follow the PEN-200 flow: enumeration first, then web and client-side attacks, exploitation and password attacks, Linux privilege escalation, Windows privilege escalation, pivoting, and finally Active Directory. Enumeration deserves disproportionate time because everything downstream depends on it. Once the material is covered, shift most of your hours to lab machines you have not seen before, and write a short report for each one.
Can I retake the exam, and how many attempts are included?
OffSec's Learn One bundle states it includes "two exam attempts" within the subscription year, which implies retakes are possible. The standalone retake policy and any waiting period or additional fee were not verifiable from the sources retrieved. Confirm current retake terms with OffSec support before purchasing, since bundled and standalone purchases may differ.
How long is the certification valid?
The validity period could not be confirmed from the official source. OffSec publishes the previously mentioned "OSCP+ Equated Scaled Scoring FAQ," which suggests the credential's scoring and possibly renewal mechanics have been revised; the article body was not accessible at retrieval time. Check the OffSec support portal and your certification record for the authoritative validity and renewal terms.
Is OSCP recognized by employers?
OffSec publishes survey-style claims on its homepage, including that "91% prefer to hire candidates with certifications" and that "89% would pay for an employee to obtain a cybersecurity certification." These are vendor-sourced figures without a cited methodology, so weigh them as marketing signals. The practical, report-based format is generally what employers reference when discussing the credential's reputation.
Do I need to write a report, and does it affect my score?
Yes - OffSec lists report submission as part of the exam format, so documentation is part of the assessment rather than an afterthought. Practice writing up lab machines as you go: record the exact commands, capture proof of each compromise, and note timestamps. Candidates who can produce clean, reproducible write-ups under time pressure are far less likely to lose points on presentation.
