Four security chiefs just agreed on something scary: AI agents behave like teenagers with access to your company's crown jewels.
At RSAC 2026, Microsoft, Cisco, CrowdStrike, and Splunk all reached the same conclusion independently. Your AI agents are storing credentials in the same place as potentially malicious code, and the blast radius when things go wrong is bigger than anyone wants to admit. Cisco's Jeetu Patel put it perfectly: agents are 'supremely intelligent, but with no fear of consequence.'
This isn't just enterprise paranoia. Every small business using AI tools right now is probably making this mistake. You give your AI assistant access to your CRM, your email, your accounting software. It logs in with your credentials, or worse, some shared service account. When that AI decides to 'help' by automatically sending emails or updating records, it's doing so with the same access level you'd give a trusted employee.
The problem is obvious once you see it. Traditional security assumes humans make decisions. Humans pause before clicking 'delete all customers.' AI doesn't pause. It optimises. And if its optimisation includes something destructive, your credentials just became the weapon.
We've seen this firsthand with clients. One company's AI scheduling assistant accidentally sent calendar invites to their entire customer database because it had email access and 'helpfully' interpreted a vague instruction too broadly. Another had their AI bookkeeper categorise a major client payment as spam income, triggering tax complications that took weeks to untangle.
The solution isn't to stop using AI. It's to stop giving it keys to the kingdom. Zero trust for AI means treating every AI action like it's coming from an intern who might be brilliant or might be having a bad day. You wouldn't give an intern your CEO's email password. Don't give it to your AI.
This means separate credentials for AI tools, limited scopes of access, and approval workflows for anything that touches critical data. Yes, it slows things down initially. But it's faster than explaining to your customers why an AI agent decided to update all their contact details to 'OPTIMISED FOR EFFICIENCY.'
Most small businesses are still in the honeymoon phase with AI, where everything feels magical and helpful. These security warnings feel like distant enterprise concerns. They're not. They're next month's crisis waiting to happen.
Create separate, limited accounts for every AI tool you use today. Don't wait for the teenager to crash the car to start teaching it how to drive safely.
