AI security on no budget: the one thing that actually matters

Most security advice for AI use is written for businesses with a compliance function and a budget for external audits. If you're a small business with neither, that advice is useless to you, not because the underlying risks don't apply, but because the recommended fix assumes resources you don't have.

Nick Harding, CEO of Fifty One Degrees, has a deliberately simple answer for businesses in that position. You don't need a security team or a paid audit to check whether your AI use is safe. Start with a free audit tool, then fix the one thing that causes most real-world risk: staff using free, personal AI accounts instead of paid company licenses.

Step one: use a free audit tool

Asked how a business with no security team, no compliance function, and no audit budget can actually check whether its AI tools are safe, Nick starts with something free.

"AI for Growth has got a fantastic tool that enables you to do an audit for free on the AI for Growth platform," he says. "Point one: go and sign up for AI for Growth and use that tool, and it will be really, really helpful for you."

This removes the "no budget for an audit" excuse entirely. A structured audit doesn't have to be a paid engagement with an external consultancy. A free, purpose-built tool gets you a genuine starting assessment at zero cost.

Step two: the one tooling decision that actually matters

Once you've got a baseline, Nick identifies a specific, common mistake that causes more real-world risk than almost anything else: businesses avoiding paid licenses.

"One of the biggest problems that we see is firms are trying to avoid paying for licenses, and so end up using the free version of all of the tooling, which do come with lots of security risks," he says.

The fix is direct: "The number one tooling choice you can make is you have to pay for licenses. It's 25 quid a month often for one of these licenses, and if you've got 10 people, that's £250 a month, which you're going to have to find from somewhere, which obviously is a challenge."

Nick doesn't pretend that cost isn't real. £250 a month for a 10-person team is a genuine expense for a small business. But he weighs it against the alternative directly: "A bigger challenge is having some kind of security risk or breach."

Why free personal accounts are the actual risk

This is worth explaining plainly, because it's the crux of the advice. Free, personal-tier AI accounts typically have weaker data protections than paid business licenses. How your inputs get stored, whether they're used for further model training, and what administrative oversight and controls are available to your business all differ meaningfully between free and paid tiers. When a staff member pastes client data, financial figures, or contract terms into a free personal ChatGPT or Claude account to get quick help with a task, that data may be handled very differently than it would be under a company-paid account with business-tier terms.

Nick's advice on this is specific and repeatable: "The number one tooling choice you can make is you have to pay for company licenses and make sure your team are using those paid-for licenses all of the time. They should not be using their personal license. They should not be using any free licenses. And that's one of the things that we see again and again with firms."

The pattern he's describing, team members reaching for whatever free tool is fastest rather than the company-provisioned paid one, is common precisely because it's the path of least resistance. Fixing it isn't a technical project. It's a policy decision and a bit of enforcement.

What this looks like in practice

For a small business with no dedicated security or compliance function, a realistic first-month plan looks like this:

• Sign up for the free AI for Growth audit tool and get a baseline read on where you currently stand.
• Check what your team is actually using. Ask directly: are people using company-paid accounts, or their own personal free logins, when they use AI tools for work?
• Budget for paid licenses across your team, even if it means starting with a smaller group of frequent users rather than the whole company at once.
• Make it a stated rule, not just a preference, that free personal accounts aren't used for business data or client information.

None of this requires specialist security expertise. It requires knowing the one thing that actually drives risk, and making a deliberate choice about it.

Being honest about what this doesn't cover

This is a genuinely useful starting point, but it isn't a complete security programme. It doesn't address every possible AI-related risk a business might face. Data governance policies, vendor risk assessment, and sector-specific regulatory requirements are all real considerations that a free audit tool and a licensing policy won't fully resolve on their own. Nick's advice here is deliberately scoped to the highest-impact, lowest-effort fix available to a genuinely resource-constrained small business, not a substitute for more thorough security work as your AI use scales up.

If your business handles particularly sensitive data, client financial records, health information, legal case material, it's worth treating this as a starting point rather than a finishing line, and seeking more specific guidance as your usage grows.

What to try this month

Do the free audit first, then have the direct, slightly uncomfortable conversation with your team about what they're actually logging into. Budget for paid licenses for your most frequent AI users, even if you can't cover the whole team immediately.
