Cybersecurity Incident Response

[YourCompany.com] · IT Department · Prepared by FullSpec · [Today's Date]

This document sets out the financial and operational case for automating your cybersecurity incident response process. It translates the time your IT Manager currently spends on manual triage, log retrieval, notification, and documentation into real dollar figures, then shows what those numbers look like after automation. FullSpec handles the entire build, configuration, and testing. Your team keeps the one decision point that genuinely requires human judgement: reviewing the classified incident and confirming the containment action.

01What the current process is costing you

7 hrs/week
Lost to manual incident work
IT Manager time across triage, logging, reporting, and notifications
$18,200/year
Annual IT staff cost on response
Based on $50/hr fully-loaded rate across 350 hours/year
90 to 195 min
Current turnaround per incident
vs. 20 to 40 min automated benchmark

The three highest-friction steps in your current process:

  • Classify Alert Severity (15 min per incident, high failure rate): No standardised rubric means severity is assigned on gut feel. Under pressure, genuine threats are downgraded and low-priority alerts consume senior attention. Inconsistent classification at this step cascades into wrong notifications and delayed containment downstream.
  • Pull Relevant Logs (25 min per incident, high failure rate): Logs are retrieved manually by logging into multiple Microsoft 365 consoles. Evidence collected late or partially is the leading cause of gaps in the audit trail. In the worst cases, log data is no longer available by the time someone looks for it.
  • Document Incident Details (30 min per incident, high failure rate): The incident report is written from memory after containment, sometimes hours later. Timeline inaccuracies, missing asset references, and incomplete action records are common. This is the step most likely to create compliance exposure and make post-incident review unreliable.

02What changes after automation

After automation, the three agents handle alert classification, log retrieval, Jira ticket creation, stakeholder notification, PagerDuty escalation, Notion report drafting, and the post-incident Slack summary without waiting for a human to initiate any step. Your IT Manager's role narrows to one deliberate decision point: reviewing the pre-classified incident in Jira or Slack and either confirming or overriding the containment recommendation. That review is estimated at 20 minutes per incident. Every other step runs in the background the moment an alert fires in Microsoft Defender.

Already using some of these tools? If Microsoft Defender, Microsoft 365, and Slack are already on your existing Microsoft licence and Notion is already in use, your incremental new spend is limited to the automation platform and PagerDuty, roughly $174/month or $2,088/year. The one-off FullSpec build cost is $6,000, bringing your true year 1 incremental outlay to $8,088 rather than the full $8,400 shown above. From year 2 the recurring cost drops to $2,400/year.

All figures in this document are based on the process details confirmed in your mapping session and on FullSpec benchmark data drawn from comparable IT incident response processes. The numbers are conservative. If your team handles more than 20 alerts per week during a period of elevated threat activity, or if the IT Manager's fully-loaded rate is higher than $50 per hour, the annual saving scales proportionally. For example, at 14 alerts per week average and $60 per hour, the annual staff cost saving rises to approximately $21,840 and the payback period shortens to around three months. Conversely, if alert volume is lower or a portion of incidents are already resolved quickly, the saving is smaller but the recurring tool cost remains the same. FullSpec recommends reviewing these figures after the first 90 days of live operation, once actual alert volumes and IT Manager review times are captured in the system, to produce a confirmed post-go-live ROI figure.

The $6,000 build cost covers the Standard build only: full triage, routing, and reporting across all three agents. If you choose the Lite build (alert routing and basic ticketing only), the build cost is $2,500 and the recurring tool cost is lower, but the staff saving is reduced because documentation and escalation steps remain manual. The Enterprise build at $12,000 adds SIEM integration and advanced playbooks. This document models the Standard build, which FullSpec recommends as the best fit for your current toolset and volume.
