I can't tell you how to sell it, but I can tell you what you would need to offer me, for me to buy it as a security tool:

Your company must: * be quite large, including dedicated security teams * have a rock solid lengthy reputation (or you would need to be a big name in cybersecurity as its founder) * demonstrable security hygiene & certifications (secure development practices, pentesting, SOC2, etc.) * offer products with flexibility to suit my needs * solve a real problem I have, not a theoretical one

It's going to be an uphill challenge to build a company in the security market, unless you're a really big name in cyber. It's a worthwhile challenge, but expect it will take either big investment or a long time starting out before you see the rewards, especially with such a niche product that doesn't really fit into the large enterprise space, and given most small shops won't want the complexity or have the budget for it.
