Read full description

Practice for the ASIS CPP® and PSP® exams with 1,000 fully explained questions. One-time purchase, no subscription. Security Pro is an unofficial CPP exam prep and PSP exam prep app: a practice test bank organized by the exam domains, with timed mock exams, flashcards and automatic error review. Written by a security professional with decades of field experience (USMC, police functions, security programs across Latin America). It is the same 1,000-question bank as the book "CPP and PSP Practice Question Bank" from the EXPERTO EN SEGURIDAD series. WHAT'S INSIDE • 1,000 CPP and PSP practice questions, each with an explanation, a "common trap" and an exam key • 10 domains: Physical Security, Crisis Management, Investigations, Risk Management, Security Principles & Practices, Business Principles & Practices, Personnel Security, Information Security and more • Timed mock exams at real exam pace (72 s/question) with per-domain results • Automatic error review: missed questions come back until you master them • Flashcards for key concepts • Per-domain progress and study streak • 100% offline: study on shift, on the bus, anywhere • Interface in English and Spanish (examen CPP y PSP en español) NO SUBSCRIPTION 10 free questions every day, from every domain, plus one free mock exam a day. Unlock everything with a single one-time purchase, for life. No accounts, no ads, no trackers. WHO IT'S FOR Security professionals preparing for the ASIS CPP (Certified Protection Professional) or ASIS PSP (Physical Security Professional) board certifications: security managers, supervisors, consultants, investigators and guards moving up. Also anyone who wants a security certification practice test that trains real professional judgment: identify risk, select proportional controls, document precisely, and act within ethical and legal limits. HOW TO STUDY WITH SECURITY PRO 1. Take a mock exam to find your weak domains. 2. Drill those domains question by question, reading every explanation and trap. 3. Let error review bring back what you missed until it sticks. 4. Repeat mock exams until you pass consistently at exam pace. Independent study material. Not affiliated with, sponsored, or endorsed by ASIS International or any other certifying organization. CPP® and PSP® are registered certification marks of ASIS International; any reference is purely descriptive. Passing any exam is not guaranteed.
