A good business case for a security tool fits on one page and answers six questions: what is the problem, what is the evidence, what are the options, what does it change, what is the risk of acting or not acting, and who owns it. Pricing goes in a separate quote. Approvers need the decision logic first.
The six sections
1. Problem. One sentence in plain words. "We cannot tell within a day whether a newly announced vulnerability affects us." Avoid product categories and acronyms.
2. Evidence. Two or three facts from your own environment, not industry headlines. How long did the last urgent patch take to find affected systems? How many findings are open and how old is the oldest? Use measured numbers from your own tickets. If you have none, say so and make measuring part of the pilot.
3. Options. At least three: do nothing, use what we have better, buy a tool. Add build it ourselves if that is realistic. A case with only one option reads like a decision already made. See build versus buy for security tools.
4. What changes. Describe the working day after adoption. Which tasks go away, which appear? Who does the new work? If the answer is "the same two people, on top of their current job", say so.
5. Risks. Of buying: data exposure, lock in, adoption failure. Of not buying: the problem in section one continues. Name what you will do to limit each risk, such as a pilot, a data processing agreement and an exit plan.
6. Ownership and review. A named owner, a date to review whether the problem improved, and the contract renewal date.
Showing value without invented numbers
Do not quote industry averages as if they were your results, and do not promise a percentage reduction before you have measured one. Better evidence is a before and after from a pilot on your own code: findings that engineers confirmed, findings fixed, time spent on triage. Approvers trust a small true number more than a large borrowed one.

Attach, do not embed
Keep the page short and attach the supporting items: pilot results, the security review summary, the contract points and the quote. Approvers who want detail will open them. The rest will read one page.
Quick check
Should the business case include the price?
Reference the quote, but keep the decision logic separate. Price is an input, not the argument.
What if we have no baseline numbers?
Say so, and make collecting the baseline the first task of the pilot.
