What you'll accomplish
By the end of this guide, you'll have Claude Pro set up as your dedicated incident report writer — turning your rough investigation notes into complete, professional incident reports in under 5 minutes. You'll spend your time investigating, not writing.
What you'll need
Go to claude.ai and sign up with your work email. Click "Upgrade" and select the Pro plan. Claude Pro gives you a much longer context window — essential for pasting full investigation timelines, log extracts, and detailed notes.
What you should see: The Claude chat interface. You'll see your subscription status in the account menu.
Find or create your organization's standard incident report template. If you don't have one, use this structure:
The key to making this fast is taking notes in a consistent format during your investigation. Create a simple notes template:
INCIDENT NOTES
Date/Time Discovered:
Alert Type:
Initial Alert Details:
[Timeline - add events as you discover them]
[timestamp] - [what you found]
[timestamp] - [action taken]
Affected Systems:
-
IOCs Found:
-
Actions Taken:
-
Still Outstanding:
-
Open claude.ai. In the chat, paste this system prompt to start the conversation:
"You are a cybersecurity incident report writer. I will give you my raw investigation notes and you will produce a professional, formal incident report. Use the following template structure: [paste your template]. Write in third person, professional tone. Do not invent details — only use what I give you. If information is missing, use [PLACEHOLDER] so I know to fill it in."
Then paste your investigation notes and ask: "Draft an incident report from these notes."
What you should see: A complete, formatted incident report that pulls all information from your notes into the proper sections. Missing information will be clearly marked as [PLACEHOLDER].
After getting the initial report, ask Claude to produce a second version: "Now write a 3-bullet-point executive summary of this incident for our CISO who will read it on their phone."
You now have both a detailed report and a short executive summary from one set of notes.
Copy the prompt you used to start the conversation. Save it in a notes file or document. Each time you need to write a report, start a new Claude conversation, paste your prompt template, then paste your investigation notes. The setup takes 30 seconds.
Basic incident report:
Draft a formal incident report from these notes. Include: Executive Summary, Timeline, Affected Systems, Root Cause, Actions Taken, Recommendations. Notes: [paste your notes]
Executive-only summary:
Write a 3-sentence executive summary of this incident for the CISO: [paste incident description]. Focus on what happened, business impact, and what was done to resolve it. No technical jargon.
Lessons learned section:
Based on this incident [paste brief description], write a "Lessons Learned" section covering: what we detected well, what we should have caught faster, and 3 specific process improvements to prevent recurrence.
Post-incident communications:
Write a notification email to the affected user [jsmith] explaining that their credentials were compromised in a phishing attack, what actions we took, and what they need to do now (change password, verify account activity).
