SPL, dashboards, alerts, ES, correlations, sources, MITRE ATT&CK, SOC runbooks.
Before starting, we run a 1-minute tech check — microphone, ambient noise, connection. If your setup isn't good enough, the test is fully refunded.
Prove you can hunt threats in Splunk ES, tune SPL searches and map detections to MITRE ATT&CK — in a 15-minute AI oral that produces a verifiable badge recruiters actually trust.
The Plume Splunk SIEM badge tests your real-world ability to operate Splunk in a professional SOC environment. Over 15 minutes, an AI examiner questions you on log source onboarding (props.conf, transforms.conf, CIM compliance), writing high-performance SPL (tstats, accelerated datamodels, job optimization), building correlation searches in Enterprise Security, MITRE ATT&CK mapping, risk-based alerting (RBA) and SOAR/Phantom orchestration. You talk, the AI listens and probes — no multiple-choice, no copy-pasting from the docs.
What sets this badge apart from a self-declared LinkedIn skill is that your spoken answers cannot be faked. The AI examiner follows up on every detail: which fields did you normalize, what throttling did you set, how did you reduce noise on a noisy notable event? The transcript is then scored by Claude Opus, which produces a 0-100 score, a level (Novice / Proficient / Advanced / Expert) and a detailed report justifying every evaluated dimension. Everything is archived and accessible via a shareable public URL.
This badge is built for SOC analysts (L2/L3), Splunk engineers, SIEM consultants, security architects and Blue Team leads who want to stand out when applying for a role, pitching for a freelance contract or documenting a career progression. Whether you run Splunk On-Prem, Splunk Cloud or you're tracking the shift to SPL2 and Mission Control, the exam adapts to your actual context and deployment reality.
Here are the concrete dimensions the AI examines during the 15-minute oral.
Writing and tuning complex SPL: tstats over accelerated datamodels, stats vs transaction trade-offs, eval chains, rex field extraction, lookup joins and practical techniques to cut job runtime and reduce indexer load.
Hands-on mastery of Splunk ES: notable event lifecycle, investigation workflows, creating and tuning correlation searches, risk scores, risk-based alerting (RBA) configuration and glass table dashboards for incident tracking.
Ingesting new data sources end-to-end: props.conf and transforms.conf configuration, custom field extraction, Common Information Model (CIM) compliance mapping and data quality validation across heterogeneous sources.
Mapping detection logic to the MITRE ATT&CK framework, building correlation searches that span multiple tactics (Initial Access, Lateral Movement, Exfiltration), configuring throttling and reducing alert fatigue systematically.
Integrating Splunk into the broader SOC ecosystem: connecting SOAR/Phantom for playbook automation, consuming threat intel feeds (TAXII, custom lookups), bridging with ticketing systems and EDR platforms end-to-end.
Running structured investigations in Splunk ES: pivoting on entities (IP, user, host), reconstructing the attack kill chain, qualifying incidents by severity and writing actionable SOC runbooks from the evidence gathered.
Knowing when Splunk is the wrong tool: ingest cost per GB, use cases better served by a data lake, honest comparison with Microsoft Sentinel, Elastic SIEM and Google Chronicle, and tracking the Cisco acquisition and SPL2 roadmap.
Final scoring is performed by Claude (Anthropic), which reads back the full transcript and applies this weighted criteria grid.
Ability to write, read and optimize non-trivial SPL queries: tstats, datamodels, eval, rex, lookups, macros. The AI evaluates technical precision and optimization logic against realistic high-volume scenarios.
Operational understanding of Splunk ES: notable event lifecycle, correlation search creation, risk-based alerting configuration, MITRE ATT&CK mapping and practical strategies for reducing alert noise in production.
Command of the ingestion pipeline: props.conf, transforms.conf, sourcetypes, CIM compliance, Heavy Forwarder vs Universal Forwarder choices, and the ability to troubleshoot parsing and normalization issues across varied sources.
Ability to run a structured investigation in Splunk ES: entity pivoting, kill chain reconstruction, incident qualification and the capacity to document a clear, actionable response runbook from the findings.
Ability to position Splunk in today's SIEM landscape, identify its limitations (cost, latency, SPL learning curve) and make a reasoned technology choice against alternatives like Sentinel, Chronicle or Elastic.
A Plume session takes about 20 minutes, from tech check to badge delivery.
The AI confirms your mic is working and the audio connection is stable. You don't need Splunk open in front of you — the exam tests what you know from practice, not your ability to demo a live environment.
You introduce yourself and walk through your most recent or most complex Splunk deployment: On-Prem, Cloud or hybrid, data volume, source types and what you actually delivered — the AI uses this to calibrate the depth of follow-up questions.
The AI examiner moves through your areas of expertise: SPL construction and tuning, ES correlation searches, log source onboarding, incident investigation, SOAR integration and SIEM trade-offs. It follows up on every answer to probe real depth — vague answers get pushed further.
You can add nuance to an earlier answer, flag a gap in your experience or share your view on where Splunk is heading — SPL2, Mission Control, the Cisco acquisition impact. The AI factors this into the final report.
Claude Opus reads the full transcript, produces a 0-100 score, a level (Novice / Proficient / Advanced / Expert) and a detailed per-criterion report. Your Splunk SIEM badge is immediately available at a shareable public URL.
Your score out of 100 translates into a level a recruiter can grasp at a glance.
You've been exposed to Splunk (pre-built dashboards, basic keyword searches) but you don't yet write SPL independently. You know the interface without mastering datamodels, CIM normalization or Enterprise Security workflows.
You write everyday SPL queries (stats, eval, rex, lookup), you navigate Splunk ES, you manage standard log sources and you can create simple alerts. You've taken part in investigations without being the primary driver.
You build complex MITRE ATT&CK-mapped correlation searches, optimize searches with tstats and accelerated datamodels, onboard custom sources via props.conf/transforms.conf and drive end-to-end investigations in Splunk ES with risk-based alerting tuned for production noise levels.
You design Splunk architectures for enterprise SOCs (indexer clustering, tiered storage, Ingest Actions), develop large-scale detection frameworks aligned to MITRE ATT&CK, integrate Splunk with complex SOAR stacks and provide credible guidance on SIEM selection in the current market (SPL2, Cisco roadmap, competitive alternatives).
No degree or years of experience required to take the badge. Here are the profiles it makes the most sense for.
You live in Splunk ES every day — qualifying incidents, writing correlation searches, managing notable events. The badge gives you an external proof of your level to support a promotion to L3 or Team Lead.
You own the platform: source onboarding, indexer configuration, search optimization and performance management. The badge documents your technical depth beyond a job title that varies widely across organizations.
Your engagements involve deploying, auditing or tuning Splunk for clients across different industries. A verified Plume badge strengthens your profile on sourcing platforms and in RFP responses without disclosing client names.
You've built a Splunk lab with BOTS datasets and practiced detection engineering, but you have no formal credential yet. The Plume exam turns hands-on lab work into a verifiable proof of skill before committing to an expensive SPLK certification.
You're accountable for your organization's detection strategy and SIEM choices. The badge validates your ability to argue technology decisions, align detection coverage to MITRE ATT&CK and evaluate build vs buy trade-offs.
Where and how your Splunk SIEM badge will help you day to day.
A hiring manager receives your resume with an Advanced Splunk SIEM badge and a link to your Plume report. They can see exactly which topics (RBA, tstats, ES investigation) were probed and at what depth — saving 30 minutes of technical screening in the first interview.
You're bidding on a Splunk ES deployment engagement. Your Plume badge with a score of 78/100 and an Advanced level strengthens your commercial proposal without having to share confidential client references or past project details.
Your manager wants objective evidence of your growth before promoting you to L3. You take the badge before and after a Splunk Enterprise Security training course — the detailed report makes the delta concrete and defensible in a performance review.
A CISO runs the badge across the entire SOC team to map real Splunk skill levels and spot collective gaps — for example, weak CIM compliance knowledge or inconsistent RBA configuration — before planning targeted training investments.
A master's student in cybersecurity built a home lab Splunk environment, ingested Windows Event Logs and Zeek data and practiced detection with BOTS datasets. The Plume badge makes that lab work credible and visible to employers who can't verify it otherwise.
An infrastructure engineer leading a migration from Splunk On-Prem to Splunk Cloud takes the badge to confirm their skills cover the operational differences: Ingest Actions, federated search and the new admin model — and to reassure stakeholders of their readiness.
A few minutes to check you have everything you need.
At the end of your session you don't just get a score — here's everything that awaits you.
You get a precise score out of 100 and an official level (Novice, Proficient, Advanced, Expert) calculated across 5 Splunk-specific dimensions: SPL, ES detection, data ingestion, incident investigation and market perspective.
Claude Opus analyses every answer and produces a structured report that explains exactly what was assessed — tstats usage, correlation search quality, MITRE ATT&CK coverage, source onboarding — with concrete improvement areas for each dimension.
Your 15-minute session is securely archived and stays private by default. You can replay it to analyse how you articulate technical concepts under pressure and refine your answers for future exams or job interviews.
A permanent URL lets you share your Splunk SIEM badge on LinkedIn, in your resume, on Toptal or in an RFP response. Recruiters see the score, the level and the report without needing to ask you for supporting documentation.
