CompTIA CySA+ is the intermediate cybersecurity analyst certification, sitting between Security+ and SecurityX (formerly CASP+). The exam emphasizes threat detection, log analysis, and incident response—skills that map to SOC analyst roles. Choose by your current skills, the exam objectives, and a sample of the teaching and practice material; no single resource is sufficient for every learner. This page reviews Dion's CySA+ course specifically: coverage depth, practice exam quality, and whether candidates can pass with Dion alone.
Try a sample and check current access and support terms before you choose a provider. Complete beginners to security operations should add a book (Mike Chapple's Sybex CySA+ guide) or a dedicated CySA+ course from a provider that lists that exam. The course's strength is its hands-on tool walkthroughs (Wireshark, SIEM); its weakness is depth on incident response procedures.
What Dion's CySA+ Course Covers
Dion's CySA+ course runs ~15 hours of lecture across the four exam domains: Security Operations, Vulnerability Management, Incident Response & Management, and Reporting & Communication. Dion sells the complete course and practice-exam pack separately on Udemy; direct bundles can include labs and different support terms. Check the exact listing. The lectures spend significant time on log analysis pattern recognition—reading SIEM alerts and identifying which are true positives. This is the strongest section and the part most aligned with the real exam's scenario-based questions.
Where Dion's CySA+ Course Falls Short
Two areas need supplementing. First, incident response procedural depth: Dion covers the NIST 800-61 framework but skims procedural detail (chain of custody, evidence preservation steps, post-incident review structure). The Sybex book by Mike Chapple covers these procedures in dramatically more depth, and they appear frequently on the real exam. Second, vulnerability management tooling: Dion covers Nessus and OpenVAS conceptually but doesn't walk through interpreting actual scan output in depth. Free TryHackMe rooms (specifically "Nessus" and "Vulnversity") fill this gap.
Who Should Use Dion CySA+ Alone vs Supplement
Choose by your current skills, the exam objectives, and a sample of the teaching and practice material; no single resource is sufficient for every learner. Supplement Dion with Sybex if: you've been out of security for 2+ years, you don't have Security+ recently, or you're studying CySA+ specifically to land a SOC analyst role (the book's incident response depth is interview-relevant).
Pro Tips
Take CySA+ within 12 months of passing Security+—Dion assumes Security+ knowledge.
Supplement Dion with TryHackMe's free SOC Level 1 rooms for hands-on practice.
Read NIST 800-61 directly (free PDF) for incident response procedural depth.
Practice reading Splunk and Wireshark output—these appear in scenario questions.
Schedule CySA+ within 90 days of finishing Dion's course; knowledge decays fast.
Common Mistakes to Avoid
Taking CySA+ without recent Security+. The knowledge gap is bigger than people expect.
Skipping the tool walkthroughs because "I already use Splunk at work." Dion's framing matches the exam's.
Dion sells the complete course and practice-exam pack separately on Udemy; direct bundles can include labs and different support terms. Check the exact listing.
Ignoring a dedicated CySA+ course from a provider that lists that exam as a second-explanation source for weak topics.
Treating CySA+ as easy because it's "just analyst stuff." It's a tough exam with very specific framing.
