Automate CrowdStrike Detection Analysis with VirusTotal and Jira

Why This Workflow Template Is Such a Time Saver

If you work in a SOC or handle security operations, you know the drill: CrowdStrike fires off a detection, you copy indicators, check VirusTotal, open Jira, create a ticket, then ping the team on Slack. It is important work, but it can get repetitive fast.

This n8n workflow template does all of that for you – automatically. It pulls detections from CrowdStrike, enriches them with VirusTotal data, creates detailed Jira issues, and sends alerts to Slack, all on a schedule. You get structured, enriched incidents without the manual copy-paste grind.

So if you have ever thought, “There has to be a better way to handle these detections,” this is exactly that better way.

What This n8n Workflow Actually Does

At a high level, the workflow:

• Runs on a schedule and pulls fresh detections from CrowdStrike
• Looks up key IOCs, like SHA256 hashes, in VirusTotal
• Builds a rich, human-friendly description of the behavior and context
• Creates a Jira issue for each detection with all the details filled in
• Sends a Slack notification so your team can jump on it quickly

The result is a clean, repeatable pipeline from detection to investigation, without anyone needing to manually pivot between tools.

When You Should Use This Template

This workflow is a great fit if:

• You use CrowdStrike for endpoint detection and response
• You rely on VirusTotal to validate or enrich file hashes and other IOCs
• Your incident tracking lives in Jira
• Your team collaborates in Slack

It is especially useful if your volume of detections is growing and you want consistent triage, or if you want to standardize how incidents are documented and shared across the team.

How the Workflow Runs from Start to Finish

Let us walk through what happens behind the scenes once you have this template set up in n8n.

1. Scheduled Start: Pulling New CrowdStrike Detections

Everything kicks off with a scheduled trigger in n8n. In this template, the workflow is configured to run daily at midnight. You can, of course, adjust that to your own cadence, but midnight is a good default for daily batch processing.

On each run, n8n calls the CrowdStrike API to:

• Query for new detection IDs since the last run
• Fetch detailed summaries for each detection

The workflow handles detection IDs in batches so you stay efficient and within API limits while still covering everything that came in.

2. Breaking Detections into Individual Behaviors

Detections can contain multiple behaviors or events, and you probably do not want to treat that as one big blob. The workflow takes each detection and splits it into individual records so that each behavior can be processed separately.

To keep things stable and compliant, the template uses batching. That means it processes a manageable number of items at a time, which helps:

• Control workflow load in n8n
• Respect CrowdStrike and VirusTotal API constraints

3. Enriching IOCs with VirusTotal

Now for the part everyone loves: enrichment. For each relevant IOC, such as a SHA256 hash, the workflow calls the VirusTotal API to grab extra context.

From VirusTotal, you can get details like:

• Reputation or detection score
• Tags and classifications
• Detection statistics across engines

To avoid hitting rate limits, the template includes a 1-second pause between VirusTotal requests. It is a small delay that keeps your workflow reliable and API friendly.

4. Pulling Everything Together Into a Clear Description

Once the data is enriched, the workflow aggregates all the behavioral details into a single, well-structured description. This is where it turns raw fields into something a human analyst can quickly read and understand.

The formatted description typically includes:

• Direct links to the relevant CrowdStrike detection dashboard
• Links to VirusTotal reports for the IOCs
• Confidence levels and detection severity
• Filenames and associated usernames
• Detailed IOC information pulled from both platforms

Instead of jumping across tools, an analyst can open the ticket and see the whole story in one place, with links ready if they want to dig deeper.

5. Creating Structured Jira Issues

Next, the workflow automatically creates a Jira issue for each detection. No more manually building tickets or forgetting to include something important.

The Jira issue is populated with:

• A concise summary of the detection
• Severity and classification pulled from CrowdStrike
• Host information and other key context
• The enriched behavioral description that combines CrowdStrike and VirusTotal data

This ensures every incident is formally tracked in your existing workflow, assigned to the right people, and ready for triage, investigation, and resolution.

6. Notifying the Team in Slack

Finally, the workflow sends out a Slack notification so nobody misses what just landed in Jira.

The Slack message can be sent to a specific user or a dedicated channel and usually includes:

• The severity level of the detection
• A short description or summary
• A direct link to the corresponding Jira ticket

That way, your team can move from “alert raised” to “investigation started” in just a couple of clicks.

Why This Workflow Makes Your Life Easier

So what do you actually gain by plugging this into your environment? Quite a lot.

• Automation: The heavy lifting of analysis is handled for you. CrowdStrike detections and VirusTotal data are stitched together automatically, so your team can focus on decisions, not data entry.
• Better Enrichment: VirusTotal adds context that turns a raw hash or behavior into something meaningful. With reputation, tags, and detection stats in one place, you can prioritize faster.
• Stronger Incident Management: Every detection becomes a structured Jira ticket. No more ad hoc tracking in chats or spreadsheets. Your incident lifecycle is documented and consistent.
• Instant Awareness: Slack notifications keep the team in the loop in real time. Critical threats do not sit unnoticed in a console waiting for someone to log in.

Getting Started with This n8n Template

If your goal is to make your SOC more efficient and your response times faster, connecting your detection, enrichment, and incident tools is a huge win. This n8n workflow template gives you a ready-made starting point.

You can adopt it as is, or customize it to:

• Adjust the schedule or trigger conditions
• Tune which fields are sent to Jira
• Change where and how Slack alerts are posted

The core idea stays the same: let automation handle the repetitive parts so your team can stay focused on real security work.
