Frequently Asked Questions
Is this a subscription or one-time payment?
All CSTI pricing is one-time. You pay once and get lifetime access to your certification track(s), including all future content updates, unlimited practice exams, and unlimited retakes.
What happens if I fail the proctored exam?
Nothing — you retake it for free. Unlike traditional certification bodies that charge $300+ per attempt, CSTI offers unlimited free retakes on every plan. Our AI tutor will even help you study the specific domains you missed.
How does CSTI compare to CompTIA Security+?
CompTIA Security+ costs $349 for the exam alone (no training included), and charges $349 per retake. CSTI Sentinel is completely free, includes all training, AI tutoring, live labs, and unlimited retakes. Plus, our employer verification portal shows competency, not just pass/fail.
Can I upgrade from Single Cert to the Full Bundle later?
Yes! If you start with a single certification, you can upgrade to the Full Stack Bundle at any time and pay only the difference. Your progress and earned certifications carry over.
Do you offer refunds?
We offer a 14-day money-back guarantee on all plans. If you're not satisfied with the platform for any reason, contact support within 14 days for a full refund — no questions asked.
