The CompTIA Security+ certification — adaptive concept practice across application/software security and the networking it depends on.
CompTIA Security+ certifies foundational cybersecurity knowledge: threats and vulnerabilities, authentication vs authorization and the protocols (MFA, sessions, JWT, OAuth2/OIDC, SAML), cryptography (hashing vs encryption, symmetric vs asymmetric, signatures, TLS/PKI), secrets management, and the common application risks — all built on an understanding of how the network actually works.
Keentune builds those security and networking concepts with questions that meet you at your level and get harder as you improve — a focused complement to the official objectives. Use the sections below to strengthen the concepts behind the exam.

What does the CompTIA Security+ practice cover?
It’s organized around the CompTIA Security+’s sections — Security and Networking — with adaptive questions for the skills behind each one. You practice the underlying abilities the CompTIA Security+ rewards rather than memorizing a fixed question set.
How does the adaptive difficulty work?
Every question is chosen near your current level in that skill. Answer well and it gets harder; miss and it eases back — so practice stays at the “optimal challenge” point where you improve fastest, and your level tracks your real progress.
Is this the official CompTIA Security+, or a practice test?
Neither. Keentune is independent skill practice ALIGNED to the CompTIA Security+’s skill areas — not official material and not a replica of the exact test format. Keentune is independent study practice, not affiliated with CompTIA.
