For founders and CEOs

Breaches happen. Your API keys don't have to be in yours.

Your product uses secret API keys to talk to services like Stripe and OpenAI. KnoxCall stores the real keys. Your apps and AI agents get a stand-in, called a token, that you can cancel at any time.

Stolen logins and keys are the most common way in.

Credential abuse started 22% of the breaches with a known entry point in Verizon's 2025 report, more than any other.

That count includes staff passwords. KnoxCall covers the API keys.

Keys get copied around. Leaked ones keep working.

One key ends up on servers, build tools, laptops and AI assistants, and every copy can leak.

Of the leaked keys and passwords that GitGuardian, a security firm, confirmed working in 2022, 64% still worked in January 2026.

Your systems hold a token. KnoxCall holds the key.

KnoxCall adds the real key to each request on its way to Stripe or OpenAI.

A leak on your side finds a token where the key used to be. Cancel it, and it stops working.

What changes for you.

Four moments every company meets, each with less to clean up.

A leakIf an app's token leaks, cancel it and issue a new one, instead of a sprint to change every key.
Someone leavesRemove them, and their access and personal tokens stop working. Tokens they made for your apps keep working until you cancel them. Ask your engineer which stored keys they could see, and change those.
A customer's security reviewWhen a customer's security review asks who used your keys, you show them the record of each call. On the free and Starter plans, that record goes back one week; higher plans keep it longer.
AI agentsGive an AI agent its own token and a cap on what it spends through KnoxCall. By default, once the cap is reached, its next call is refused. The free and Starter plans include one AI agent; higher plans include more.

What KnoxCall does not do.

  • It does not stop a breach. It keeps your real API keys out of your apps and servers.
  • It does not protect your staff's passwords or logins.
  • It does not protect the data in your own database.
  • A stolen token still works until you cancel it, and its calls are on the record.
  • It covers keys your own software uses, not access you've given one vendor to another, like a sales tool connected to your email.

Your API keys in one place, and how that place is guarded.

  • Each new account gets a master key used only for that company. Your stored keys are encrypted with it.
  • On the Enterprise plan, you can lock that master key with a key held in your own cloud account.
  • Sensitive changes go into a log built to show tampering, and we check it every day.
  • People on your team with the right permissions can still view a stored key.
  • Calls you send through KnoxCall depend on us being up. Our status page is public.

Say yes, and your engineer does the rest.
