An incident response plan template is a pre-structured document that organisations customise to define how they detect, classify, contain, eradicate, and recover from cybersecurity incidents, with built-in notification workflows for GDPR (72-hour breach reporting), NIS2 (24-hour early warning), and other regulatory obligations.
The difference between a theoretical understanding of incident response and an operational capability is a documented, tested plan. IBM's Cost of a Data Breach Report 2025 found that organisations with a tested incident response plan save an average of $2.66 million per breach. Yet according to the Ponemon Institute, 54% of organisations either lack a formal incident response plan entirely or have one that has never been tested.
The template below is designed to be copied, customised, and put into use. Every section includes fill-in-the-blank fields, checkbox action items, and regulatory references so your plan is compliant from day one. Replace [ORGANISATION NAME] with your company name, adapt the severity levels to your infrastructure, and add any industry-specific requirements that apply.
For a comprehensive explanation of incident response concepts, the NIST framework, tabletop exercises, and maturity models, see the Incident Response Plan Guide. This article is the template itself.

Why You Need an Incident Response Plan
The regulatory landscape leaves no ambiguity: every organisation that processes personal data or operates essential or important services in the EU must have a documented incident response capability.
The business case is equally clear:
- $2.66 million average savings per breach for organisations with a tested IR plan (IBM Cost of a Data Breach Report 2025)
- 258 days average time to identify and contain a breach without a formal plan, versus 184 days with one (IBM 2025)
- EUR 4.2 billion in GDPR fines issued during 2025 alone (DLA Piper GDPR Fines Survey 2026), with inadequate breach response consistently cited as an aggravating factor
- NIS2 penalties of up to EUR 10 million or 2% of global turnover for essential entities that fail to meet incident notification requirements (Article 34)
Having a plan is the minimum requirement. Having a plan that is documented, distributed to your team, and tested through regular tabletop exercises is what actually reduces damage when an incident occurs. For a deep dive into building your plan from the ground up, see the Incident Response Plan Guide. For broader NIS2 obligations beyond incident reporting, see the NIS2 Complete Guide.
Regulatory Requirements for Incident Response
Before customising the template, understand which regulations apply to your organisation. The table below summarises the incident response requirements of the four most common EU frameworks.
| Regulation | Key Articles | Notification Timeline | What Must Be Reported | Penalty for Non-Compliance |
|---|---|---|---|---|
| GDPR | Articles 33, 34 | 72 hours to supervisory authority (from awareness); without undue delay to data subjects if high risk | Nature of breach, categories and approximate number of data subjects, likely consequences, measures taken or proposed | Up to EUR 10 million or 2% of global turnover |
| NIS2 | Article 23 | 24 hours (early warning); 72 hours (incident notification); 1 month (final report) | Incident severity and impact, initial assessment and indicators of compromise, cross-border impact, root cause and remediation (final report) | Up to EUR 10 million or 2% of global turnover (essential entities) |
| DORA | Articles 17, 18, 19 | 4 hours (initial classification); 72 hours (intermediate report); 1 month (final report) | Classification, impact on financial services, root cause, recovery actions | Determined by competent financial authority per member state |
| ISO 27001 | Annex A.5.24-5.28 | As defined in your ISMS procedures | Incident detection, reporting, assessment, response, and lessons learned | Certification withdrawal; no direct financial penalty |
If your organisation falls under multiple frameworks (common for financial institutions subject to both GDPR and DORA, or for NIS2 essential entities processing personal data), your incident response plan must satisfy the strictest applicable timeline. The template below is designed to accommodate overlapping requirements.

Template Section 2: Incident Classification
Use the following four-tier classification system to determine response urgency, team activation, and escalation requirements. Customise the examples column to reflect your specific infrastructure and data types.
2.1 Severity Levels
| Priority | Name | Definition | Response Time | Escalation | Examples |
|---|---|---|---|---|---|
| P1 | Critical | Business-critical systems unavailable; confirmed large-scale data breach; ransomware spreading across infrastructure; imminent regulatory notification required | Immediate (within 15 minutes of detection) | Full IR team activation; executive notification within 30 minutes; board notification within 2 hours | Ransomware encrypting production; breach of more than 10,000 records; complete service outage; active attacker in network |
| P2 | High | Significant incident with confirmed data exposure (limited scope); important systems compromised; targeted attack in progress but contained to limited area | Within 1 hour of detection | Core IR team activation; management notification within 2 hours; DPO and Legal activated | Compromised admin account with data access; breach of fewer than 10,000 records; targeted phishing with credential theft; critical vulnerability actively exploited |
| P3 | Medium | Security incident contained to limited scope; no confirmed data exposure; non-critical systems affected | Within 4 hours of detection | Technical team responds; Incident Commander notified; logged and tracked | Malware on single endpoint (contained); suspicious activity on non-critical system; successful phishing (no data access confirmed); unauthorised access attempt (blocked) |
| P4 | Low | Minor security event with no business impact; easily remediated; informational | Within 24 hours (next business day acceptable) | Technical team handles; logged for trending and metrics | Phishing email reported (not clicked); vulnerability scan finding; minor policy violation; failed login attempts |
2.2 Escalation Triggers
Any of the following conditions require immediate escalation by one severity level:
- Personal data breach confirmed (any volume): escalate to P2 minimum; activate DPO and Legal
- Ransomware or destructive malware detected: escalate to P1 immediately
- Incident involves customer, client, or patient data: escalate to P2 minimum
- Attacker activity is ongoing and expanding: escalate to P1
- Media enquiry received about the incident: escalate to P1; activate Communications
- Law enforcement contacts the organisation: activate Legal immediately
- Incident cannot be contained within 4 hours: escalate by one level
- Third-party/vendor systems are involved: activate vendor management procedures

Template Section 4: Response Phases
This section follows the six NIST-aligned phases. Each phase includes checkbox action items. During an active incident, the Incident Commander and IR Team Lead work through these items sequentially, checking off completed actions and documenting timestamps.
Phase 1: Preparation
Preparation happens before any incident. These items should be completed and maintained continuously.
- Incident response plan documented and approved by management (this document)
- IR team roster complete with named individuals, alternates, and 24/7 contact details (Section 3)
- Severity classification matrix defined and understood by all team members (Section 2)
- Detection tools operational: SIEM, EDR/XDR, IDS/IPS, DLP, email security
- SIEM:
[TOOL NAME, STATUS] - EDR/XDR:
[TOOL NAME, STATUS] - IDS/IPS:
[TOOL NAME, STATUS] - DLP:
[TOOL NAME, STATUS]
- SIEM:
- Log retention configured: minimum 12 months of security logs retained and accessible
- Forensic toolkit available: forensic imaging software, write blockers, chain-of-custody forms, secure evidence storage
- Out-of-band communication channel established (not reliant on potentially compromised infrastructure):
[TOOL/CHANNEL, e.g., separate Signal group, dedicated mobile phones, satellite phone] - Communication templates pre-drafted and reviewed by Legal (Section 6)
- Regulatory notification portals bookmarked and credentials accessible to DPO/Legal
- GDPR supervisory authority:
[DPA NAME, PORTAL URL] - NIS2 CSIRT:
[CSIRT NAME, PORTAL URL] - DORA competent authority:
[AUTHORITY NAME, PORTAL URL]
- GDPR supervisory authority:
- External party retainers in place: forensics firm, external legal counsel, cyber insurance, crisis PR (Section 3.3)

Phase 2: Detection and Analysis
Begin this phase when a potential incident is identified. Document all timestamps.
- Incident detected via:
[SIEM alert / EDR alert / user report / external notification / threat intelligence / other] - Detection timestamp recorded:
[DATE, TIME, TIMEZONE] - Initial triage completed: Is this a confirmed incident or a false positive?
- Result:
[Confirmed incident / False positive / Under investigation]
- Result:
- Incident type identified:
[Malware / Ransomware / Phishing compromise / Data breach / Insider threat / DDoS / Vulnerability exploitation / Vendor/supply chain / Other] - Severity level assigned using classification matrix (Section 2):
[P1 / P2 / P3 / P4] - Scope assessment completed:
- Systems affected:
[LIST] - Data potentially affected:
[TYPE AND VOLUME] - Users/accounts affected:
[LIST OR COUNT] - Geographic scope:
[LOCATIONS / JURISDICTIONS]
- Systems affected:
- Personal data involved?
[Yes / No / Under investigation]- If yes: Categories of data subjects:
[EMPLOYEES, CUSTOMERS, PARTNERS] - If yes: Categories of personal data:
[NAMES, EMAIL, FINANCIAL, HEALTH, OTHER] - If yes: Approximate number of records:
[COUNT OR ESTIMATE] - If yes: GDPR 72-hour clock starts now. Deadline:
[DETECTION TIME + 72 HOURS]
- If yes: Categories of data subjects:
- NIS2 applicability assessed: Does this incident significantly impact service provision?
- If yes: NIS2 24-hour clock starts now. Early warning deadline:
[DETECTION TIME + 24 HOURS]
- If yes: NIS2 24-hour clock starts now. Early warning deadline:
- Evidence preservation initiated: logs collected, forensic images created if needed, chain of custody documented
- Incident Commander notified (for P1/P2: immediate; for P3: within 4 hours)
- Incident log created with unique incident ID:
[INC-YYYY-NNN]
Phase 3: Containment
Goal: stop the incident from spreading while preserving evidence for investigation.
Short-term containment (immediate):
- Isolate affected systems from the network (disconnect, disable network ports, modify firewall rules)
- Disable compromised accounts (reset credentials, revoke active sessions, disable MFA tokens)
- Block known malicious indicators: IP addresses, domains, file hashes added to blocklists
- Preserve system state before any changes: forensic image, memory dump, log snapshots
- Document all containment actions with timestamps and responsible persons
Long-term containment (stabilisation):
- Redirect traffic to clean systems if service continuity is required
- Implement temporary network segmentation to isolate affected zones
- Apply emergency patches to exploited vulnerabilities (if patch available and tested)
- Deploy additional monitoring on adjacent systems to detect lateral movement
- Assess whether backup systems are compromised before planning restoration
- Verify containment is holding: no new indicators of compromise, no further spread
Phase 4: Eradication
Goal: remove the threat from the environment entirely.
- Root cause identified:
[DESCRIPTION OF HOW THE ATTACKER GAINED ACCESS / HOW THE INCIDENT OCCURRED] - All malware removed from affected systems (using EDR, AV, or reimaging from known-good baseline)
- Attack vector closed: vulnerability patched, misconfiguration corrected, compromised credential permanently revoked
- Persistence mechanisms removed: scheduled tasks, registry entries, backdoor accounts, web shells, modified startup scripts
- All potentially compromised credentials reset (not just confirmed compromised ones)
- Detection rules updated: new IOCs added to SIEM, EDR, and network monitoring
- Scan all potentially affected systems to confirm clean state
- Third-party/vendor remediation confirmed if the incident involved external systems
Phase 5: Recovery
Goal: restore normal operations safely and verify the threat is eliminated.
- Backup integrity verified before restoration (ensure backups are not compromised)
- Systems restored from clean backups or rebuilt from known-good images
- Security baseline confirmed: all patches applied, security controls active, configurations verified
- Network connectivity restored gradually (not all at once) with enhanced monitoring
- User access restored with fresh credentials where applicable
- Enhanced monitoring in place for 72 hours minimum post-recovery to detect recurrence
- Business operations validated: affected services tested and confirmed functional
- Incident Commander reviews recovery status and decides whether to declare incident resolved
- Incident status updated:
[Resolved / Monitoring / Partially recovered]
Phase 6: Post-Incident Activity
Goal: learn from the incident and improve defences. Conduct the post-incident review within 5-10 business days of incident closure.
- Post-incident review (PIR) meeting scheduled:
[DATE, TIME]- Attendees: all IR team members who participated, plus management sponsor
- Complete incident timeline documented (from first indicator to full resolution)
- PIR questions addressed:
- What happened and what was the root cause?
- How was the incident detected? Could we have detected it earlier?
- Was the severity classification accurate? Was escalation timely?
- Did containment work effectively? Did the incident spread after initial containment?
- Were regulatory notifications submitted on time? Were they accurate?
- What worked well? What needs improvement?
- Incident report finalised including: timeline, root cause analysis, impact assessment, response effectiveness, and recommendations
- Action items assigned with owners and deadlines:
- Technical improvements:
[LIST] - Process improvements:
[LIST] - Training needs:
[LIST] - Policy/plan updates:
[LIST]
- Technical improvements:
- Incident response plan updated to incorporate lessons learned
- NIS2 final report submitted (if applicable, within 1 month of incident notification)
- Metrics updated: MTTD, MTTR, containment time, notification compliance
- Incident record archived with all evidence, logs, communications, and reports

This template is designed to work for organisations of any size, from a 20-person company to a multinational enterprise. The structure remains the same; the level of detail scales with your complexity.
Step 1: Replace all placeholders
Search the document for every instance of [BRACKETED TEXT] and replace with your organisation's specific information. Key placeholders:
-
[ORGANISATION NAME], your legal entity name -
[DPO NAME / CISO NAME], your document owner -
[DATE], effective date and review dates - All named individuals in the roles table (Section 3)
- All tool names in the Preparation phase
- All external party contact details (Section 3.3)
- Supervisory authority and CSIRT portal URLs
Step 2: Adapt severity levels
The P1-P4 classification is a starting point. Adjust the definitions and examples to match your infrastructure:
- Add examples specific to your critical systems and data types
- Adjust response times if your SLAs or regulatory environment requires faster action
- Define escalation triggers relevant to your industry (e.g., financial transaction fraud for FinTech, patient data for healthcare)
Step 3: Add industry-specific requirements
- Financial services (DORA): Add the 4-hour initial classification notification and the intermediate report at 72 hours
- Healthcare: Add HIPAA breach notification procedures if processing US patient data
- E-commerce (PCI DSS): Add acquirer and card brand notification procedures
- NIS2 essential/important entities: Verify your sector classification and confirm the correct national CSIRT
Step 4: Review with Legal and Security
- Legal review of all communication templates and notification procedures
- Security team review of technical procedures (containment, eradication, recovery)
- DPO review of GDPR notification workflow and data subject assessment criteria
- Management review and formal approval (sign-off)
Step 5: Distribute and train
- Store the approved plan in a location accessible to all IR team members (and also available offline or via out-of-band channel)
- Brief all IR team members on their roles and the plan's structure
- Conduct an initial tabletop exercise within 30 days of plan approval
- Schedule recurring tabletop exercises (minimum twice per year)

Frequently Asked Questions
Is this template enough to satisfy GDPR and NIS2 requirements?
This template covers the core structure and notification workflows required by GDPR Articles 33-34 and NIS2 Article 23. However, a template alone is not compliance. You must customise it with your organisation's specific details, obtain management approval, distribute it to your IR team, and test it through regular tabletop exercises. Supervisory authorities evaluate not just whether a plan exists, but whether it is operational and tested. For a complete guide on GDPR compliance beyond incident response, see the GDPR Compliance Checklist.
How often should we update this incident response plan?
At minimum, review and update the plan annually. Additionally, update it after every P1 or P2 incident (incorporating lessons learned), after significant changes to your infrastructure or team, after regulatory changes affecting your notification obligations, and after each tabletop exercise reveals gaps. Version-control the document and maintain a change log (Section 1.4).
Can we use this template if we are a small company?
Yes. The template scales to any organisation size. A 20-person company will have fewer named individuals (one person may fill multiple roles), simpler infrastructure, and fewer external parties. The structure, phases, and notification requirements remain the same regardless of size. Start with the sections that address your highest-risk scenarios and expand from there.
What is the difference between this template and the incident response plan guide?
The Incident Response Plan Guide is an educational resource that explains incident response concepts, the NIST framework, tabletop exercise methodology, common mistakes, and maturity models. This article is the template itself: a document you copy, customise, and deploy as your organisation's actual incident response plan. Use the guide to understand the concepts; use this template to implement them.
Do we need different templates for GDPR breaches versus cybersecurity incidents?
No. A single incident response plan should cover all incident types. The template includes decision points where you assess whether personal data is involved (triggering GDPR obligations), whether essential/important services are affected (triggering NIS2 obligations), and whether financial services are impacted (triggering DORA obligations). The notification tracker in Section 5 handles overlapping requirements within one unified workflow.
What should we do after completing the template?
After customisation and management approval, take these immediate actions: (1) distribute the plan to all IR team members and ensure offline access, (2) schedule a tabletop exercise within 30 days to test the plan with a realistic scenario, (3) verify that all detection tools listed in the Preparation phase are operational, (4) confirm that all external party retainers are current and contact details are accurate, and (5) set a calendar reminder for the next annual review.
