FAQ

How should I estimate projected incident hours?

Combine tabletop exercises, historical incident logs, and regulatory notification scenarios to model containment plus investigative workload across likely events.

What if my retainer includes different rate cards for analysts and principals?

Blend the rates into a weighted average or run the calculator twice—once per labor tier—and add the totals to approximate the mixed cost.

Do unused hours roll over?

Most contracts forfeit unused hours at renewal. The calculator highlights remaining hours so you can schedule proactive hunts or compromise assessments before they expire.

Additional Information

  • Many retainers reset annually—unused hours often expire, so track the unused total returned in the result.
  • Overage rates vary by region and response time commitments; $450/hour reflects common U.S. market pricing for senior incident responders.
  • Layer in travel or hardware expenses separately if your provider bills them in addition to hourly labor.
