Want to Become a SOC Analyst? Here's Exactly Where I Learned (Without Spending Thousands)
There are a lot of expensive SOC/Blue Team training programs. Cybrary costs money. AlteredSecurity CRTP costs money. Most "professional" SOC training costs $1,000-3,000 per course.
I learned SOC skills without paying for any of them. Free platforms: LetsDefend, TryHackMe's SOC Level 1, Splunk's official training, Wazuh documentation, Microsoft Learn, and hands-on practice at Inhok Technologies during my internship.
This isn't an article recommending expensive programs. This is an honest review of 6 free-or-low-cost platforms for learning SOC skills, based on what actually prepared me for real SOC work at an MSSP.
📚 Books That Helped Me Build Strong Security Foundations
These platforms taught me practical SOC skills, but books helped me understand the underlying concepts in much greater depth. If you're serious about building a long-term cybersecurity career, these are excellent resources.

- LetsDefend — Realistic alert-driven simulation
- TryHackMe SOC Level 1 — Foundational and structured
- BTLO (Blue Team Labs Online) — Forensics and investigation
- Splunk — The actual tool you'll use
- Wazuh — Open-source SIEM alternative
- Microsoft Learn — Cloud and Windows security
- How to combine them into a coherent learning path
Platform 1: LetsDefend
LetsDefend simulates a real SOC environment. You get alerts coming into your dashboard. You investigate them. You make triage decisions. You write alert summaries. The simulation is realistic: you have too many alerts, incomplete information, and have to make decisions with partial data — exactly like real SOC work.
- Most realistic SOC simulation available
- Free tier is genuinely useful (not neutered)
- Alerts feel like real alerts, not CTF-style challenges
- Forces you to write incident summaries (communication skill)
- Ranks alerts by severity — teaches triage prioritization
- Community feedback on your responses helps learning
- Learning curve is steep — assumes you know baseline defensive concepts
- Free tier limits number of active cases (paid unlocks more)
- Tool interface is clunky (but realistic to actual SOC tools)
- No hands-on SIEM querying — more alert analysis, less log diving
- Some alerts require domain-specific knowledge you might not have
My experience: I used LetsDefend starting month 3 of my learning. I'd completed TryHackMe SOC Level 1, so I had foundational knowledge. LetsDefend forced me to apply that knowledge to realistic alert investigation. It revealed my blind spots: I could identify malicious activity, but I was slow at writing clear incident summaries and making appropriate escalation decisions. That's exactly what I needed to improve before my Inhok internship.
Platform 2: TryHackMe SOC Level 1
Structured learning path covering SIEM concepts, log analysis, alert triage, incident response, and threat intelligence. Each room builds on previous knowledge. Most rooms are free; some require subscription. Progression is clear: concept → hands-on practice → assessment.
- Structured progression (foundations first, specialization later)
- Each room has learning objective + hands-on practice
- Covers both defensive and incident response perspectives
- Web-based labs — no local setup required
- Free tier has most essential rooms
- Content matches actual SOC job descriptions
- Rooms are sometimes repetitive (learning by repetition)
- Some advanced rooms behind subscription paywall
- Lab environments are simulated, not production-like
- Limited tool variety (more conceptual than tool-specific)
My experience: I started with TryHackMe SOC Level 1 in month 2 of my cybersecurity learning. At that point, I'd finished Pre Security and Web Fundamentals. SOC Level 1 made the leap from "network/application knowledge" to "how SOCs actually work." Rooms on SIEM concepts, log analysis, and alert triage were directly applicable to my later internship. The structured path prevented me from jumping into advanced topics before understanding foundations.
Platform 3: BTLO (Blue Team Labs Online)
BTLO focuses on hands-on forensics, log analysis, and malware analysis investigations. Unlike LetsDefend (alert simulation), BTLO gives you raw artifacts: packet captures, disk images, log files. You do the investigation. More technical, less alert-driven.
- Real forensics work — not simulated alerts
- Variety of investigation types (malware, network, forensics)
- You learn actual tools (Wireshark, Volatility, etc.)
- Ranked difficulty helps progression
- Write-ups available after solving (learn from others)
- Labs don't expire — practice at your own pace
- Subscription-only (no free tier)
- More forensics-heavy than SIEM-heavy
- Steep learning curve on some labs
- Tool proficiency is assumed (you need to know Wireshark, etc.)
My experience: I didn't use BTLO during my learning phase — I prioritised free platforms. But in retrospect, I would have used it for month 4-5 after TryHackMe SOC Level 1. BTLO labs focus on forensic investigation and malware analysis — skills that are valuable for SOC Level 2+ roles and threat hunting. Entry-level SOC work is mostly alert triage, but the forensics knowledge helps you understand what you're looking at.
Platform 4: Splunk Official Training
Splunk's free training (Splunk Fundamentals Part 1 & 2, Search Processing Language courses) teaches you how to actually use Splunk. Not security concepts — Splunk mechanics. How to write queries. How to create dashboards. How to understand the search processing language. This is the tool you'll use 40 hours a week as a SOC analyst.
- Completely free official training from Splunk
- Hands-on labs with real Splunk environment
- Certification available (Splunk Core Certified User)
- Content is kept up-to-date with Splunk releases
- Directly applicable to SOC work
- Essential for getting SOC job at companies using Splunk
- Teaches tool, not security concepts
- Requires baseline understanding of logs and data
- Learning curve is steep for absolute beginners
- No security context — just "here's how to query Splunk"
My experience: I completed Splunk Fundamentals Part 1 & 2 in month 5 of learning. My Inhok internship used Splunk heavily. The official training was invaluable — I went into the internship confident using Splunk's search language, creating dashboards, and building detection rules. New interns without this training struggled with the tool itself; I could focus on learning security analysis. Splunk certification was also mentioned by recruiters as a positive credential.
Platform 5: Wazuh Documentation + Hands-On Lab
Wazuh is a free, open-source SIEM/log management tool. Documentation is excellent, and you can deploy it locally to learn. No subscription, no enterprise limitations. Learning Wazuh teaches you SIEM concepts in a tool that's actually free and deployable.
- Completely free and open-source
- Can deploy locally — not cloud-dependent
- Documentation is high quality
- Learning transfers to other SIEMs (ELK, Splunk)
- Actually used by companies (not just for learning)
- Community support is active
- Local deployment requires some sysadmin knowledge
- Learning by documentation is slower than structured courses
- No built-in labs like TryHackMe/LetsDefend
- Steeper learning curve than commercial SIEM tools
My experience: I deployed Wazuh locally in month 4 and set up a home lab with it. My Inhok internship used both Splunk and Wazuh. Learning Wazuh first (free, hands-on deployment) helped me understand SIEM concepts better before jumping into Splunk's commercial interface. Setting up detection rules, understanding log ingestion, and querying data — those skills transfer directly. Wazuh is also increasingly common in smaller organizations and MSSPs, so it's practical knowledge.
Platform 6: Microsoft Learn
Microsoft Learn has free training on Azure security, Windows security, Microsoft Defender, and cloud security concepts. Not SOC-specific, but foundational for understanding modern enterprise security architecture.
- Completely free official Microsoft training
- Covers modern cloud security (increasingly important)
- Hands-on labs with free Azure credits
- Content is current with Microsoft security updates
- Relevant for cloud-native SOC work
- Not SOC-specific (more general security/cloud)
- Assumes networking knowledge
- Learning path is not sequenced for SOC roles
- Heavy focus on cloud, less on on-premises
My experience: I used Microsoft Learn in month 5 to understand Windows security controls and Azure security fundamentals. My Inhok internship monitored both on-premises and cloud infrastructure. Understanding Windows Event Log categories and Azure security metrics was important for comprehensive log analysis and alert creation. Microsoft Learn filled gaps that platform-specific training didn't cover.
How I Combined These Into a Complete SOC Learning Path
Months 1-2 (TryHackMe Pre Security + Cyber Security 101): Foundational concepts. Networking basics. Incident response overview. Not SIEM-specific, but essential context for everything that follows.
Months 3-4 (TryHackMe SOC Level 1 + TryHackMe Web Fundamentals): Specialist SOC knowledge. SIEM concepts. Log analysis fundamentals. Alert triage concepts. At end of month 4, I had theoretical knowledge but zero hands-on SIEM experience.
Months 5-6 (Splunk training + Wazuh local deployment + LetsDefend practice): Hands-on tool proficiency. Splunk official training taught query language. Wazuh deployment taught SIEM architecture. LetsDefend taught alert triage workflow. This is when learning moved from theoretical to practical.
Months 7-8 (Internship at Inhok Technologies): Real work. All prior learning applied to actual security monitoring. Gaps in knowledge became immediately visible. Supporting learning (Microsoft Learn for cloud security, continued LetsDefend practice) filled those gaps.
The Optimal SOC Learning Path (Sequenced)
Phase 1: Foundations (Months 1-2)
- TryHackMe Pre Security — Networking and OS fundamentals (20-25 hrs)
- TryHackMe Cyber Security 101 — Defensive security intro (25-30 hrs)
Time commitment: 45-55 hours. Why this order: You need to understand networks before understanding SIEM. You need defensive concepts before SOC-specific knowledge.
Phase 2: SOC Concepts (Months 3-4)
- TryHackMe SOC Level 1 — SIEM and alert concepts (35-45 hrs)
- TryHackMe Web Fundamentals — Application attacks (30-35 hrs) [parallel]
Time commitment: 65-80 hours. Why: SOC work involves monitoring web attacks and application logs. Understanding both SIEM mechanics and web attacks is essential.
Phase 3: Tool Proficiency (Months 5-6)
- Splunk Fundamentals Part 1 & 2 (if Splunk is your target tool) — 25-30 hrs
- OR Wazuh documentation + local deployment (if open-source is your target) — 20-25 hrs
- LetsDefend practice (alert investigation workflow) — 20-30 hrs [parallel]
Time commitment: 45-60 hours. Why: This is where learning moves from conceptual to practical. You choose SIEM tool based on target jobs.
Phase 4: Supporting Knowledge (Month 7+)
- Microsoft Learn (cloud and Windows security) — 15-20 hrs
- BTLO labs (forensics and investigation) — ongoing [optional/paid]
- Real-world labs or internship — apply everything (40+ hrs/week)
Time commitment: Variable. Why: Supporting knowledge fills gaps and maintains depth. Real work is the ultimate teacher.
You can do this entire path (Phase 1-3, ~170 hours) for free. Splunk training is free. Wazuh is free. TryHackMe SOC Level 1 is mostly free (subscription helps but isn't required). LetsDefend free tier is genuinely useful.
But you will likely want subscriptions: LetsDefend ($10-20/month) for more alert practice, TryHackMe subscription ($10-30/month) for advanced rooms, BTLO ($40-50/month) for forensics training. Budget: $100-200 total for 6-8 months of learning is reasonable, and much cheaper than formal SOC training courses.
Real value comes from applying what you learn in a real environment: internship, home lab, bug bounty, or actual job. The platforms teach concepts and give hands-on practice. The environment teaches judgment and professional skills.
🔐 Protect Your Learning Accounts
If you're using TryHackMe, LetsDefend, Microsoft Learn, GitHub, and your primary email, protecting those accounts is just as important as learning new skills. A hardware security key offers stronger protection than SMS-based authentication.
