When you’re a one-person operation, security often feels like a large-company problem. You don’t have a CTO, a security team, or an IT department. You have a laptop, a browser, and a stack of SaaS tools that know a lot about your business.
Then you add AI to the mix — and suddenly you’re pasting client data into ChatGPT, running your customer emails through automation workflows, feeding sensitive business information into AI assistants, and storing API keys in places you hope are secure.
The security risks here are real, but they’re also manageable with the right habits. You don’t need enterprise infrastructure. You need to understand what the actual risks are, which ones matter most for your situation, and what you can do about them without spending your week managing security instead of running your business.
Understanding the Real Risks
Before diving into what to protect against, it’s worth being clear about what the risks actually are — because “AI security” often triggers vague anxiety rather than specific, actionable concern.
The main risk categories for solopreneurs using AI:
Data exposure via AI tools: When you paste content into ChatGPT, Claude, Gemini, or any AI tool, that data goes to the provider’s servers. Depending on the platform’s settings and your account type, it may be used to train future models. Client data, proprietary business information, or personal details shared this way could be more broadly accessible than you intend.
API key exposure: If you’re using AI APIs directly (OpenAI, Anthropic, Google) or in automation tools like Make.com or Zapier, you’re dealing with API keys — essentially passwords that grant access to services and often carry billing implications. Exposed keys get scraped and abused.
Third-party automation risks: Every automation that connects your apps creates a potential vulnerability chain. If one service in your Make or Zapier scenario is compromised, data flowing through the entire scenario is potentially affected.
Phishing and AI-generated attacks: AI has made social engineering attacks significantly more convincing. Phishing emails, voice cloning calls, and fake invoices are harder to detect than ever. Solopreneurs are frequently targeted because they make financial decisions without a corporate approval process.
Over-sharing in prompts: Many people inadvertently include more sensitive information in AI prompts than necessary — full client names, financial details, proprietary strategies — when a sanitised version of the information would produce the same result.
What to Actually Protect
Not all data is equally sensitive. Prioritise protection in this order:
Tier 1 — Protect rigorously: - Client personal data (names, emails, financial details, contact information) - API keys and credentials - Financial records and banking information - Proprietary client deliverables or strategies - Login credentials for any system
Tier 2 — Handle with care: - Business strategy and plans not yet public - Pricing structures and negotiation details - Client relationship details and communications - Vendor contracts and terms
Tier 3 — Lower risk: - General business processes and workflows - Published or near-published content - Non-client-specific research and notes
For anything in Tier 1, apply the security measures below as a standard practice. For Tier 2, apply judgment. For Tier 3, the risk of AI processing is generally low.
Practical Security Measures for Every Solopreneur
Build this with the free AI Toolkit
Starter prompts, system maps, and the first workflow for each DSHQ system — the fastest way to put this into practice.
Get the Free Toolkit1. Configure Your AI Tool Privacy Settings
This is the first and most actionable step. Every major AI platform has data training settings — and in most cases, the default allows your conversations to be used for model training.
ChatGPT: Settings → Data Controls → Turn off “Improve the model for everyone.” With this off, your conversations are not used for training.
Claude (Anthropic): Anthropic’s usage policies differ by product. In Claude.ai, conversations are not used to train models by default for paid accounts. Check your specific account settings.
Google Gemini: Settings → Gemini Apps Activity → Pause activity to prevent conversation storage.
If you’re using the API directly (not the consumer chat interfaces), your data is generally not used for training by most providers — but verify this in the provider’s API terms.
For business-critical or client work, consider using the API directly rather than consumer chat interfaces, or upgrade to a business/enterprise tier that offers stricter data handling guarantees.
2. Sanitise Before You Paste
A simple but powerful habit: before pasting content into any AI tool, remove or anonymise identifying information that isn’t necessary for the task.
Instead of: “Write a follow-up email to John Smith at Acme Corp regarding the $45,000 proposal we sent last Tuesday for their product launch campaign.”
Use: “Write a follow-up email to a client regarding a proposal we sent last week for a marketing campaign.”
The AI produces the same quality output. The sensitive details stay out of the AI’s servers.
Build this as a reflex: pause before pasting, ask “does the AI actually need this specific information?” If not, remove it.
3. Secure Your API Keys
API keys are high-value targets. A leaked OpenAI or Anthropic API key can result in significant unauthorised charges and access to your data. Treat them like passwords — more seriously, actually, because they’re often harder to notice when compromised.
Never put API keys in: - Plain text files - GitHub repositories (even private ones, if others have access) - Shared documents or Notion pages - Slack messages or emails
Do put API keys in: - Environment variables in your code - Your automation platform’s secure credential store (Make.com and Zapier both have secure connection storage) - A password manager (1Password, Bitwarden) with a separate vault for API credentials
Monitor usage: Set spending limits and alerts on your API accounts. If a key is compromised, you’ll see unusual usage spike before your bill does. Both OpenAI and Anthropic allow you to set usage limits and email notifications.
Rotate keys periodically: Create a new key every 3–6 months and update your automations. Delete old keys. This limits the damage window if an old key was ever exposed without your knowledge.
4. Use Separate, Scoped Connections in Automations
In Make.com, Zapier, or any automation tool, each app connection uses credentials that grant the automation access to that app. The principle of least privilege applies: grant only the access the automation actually needs.
Practical examples: - If an automation needs to read your Google Sheets, connect a Google account that can read sheets but doesn’t have access to your Google Drive archives - Create a separate Gmail account for automation outgoing emails rather than connecting your primary business email - Use Notion API connections scoped to specific databases rather than your entire workspace
This way, if an automation connection is compromised, the blast radius is limited to what that connection could access — not everything.
5. Enable MFA Everywhere, No Exceptions
Multi-factor authentication (MFA) is the single highest-impact security measure for any online account. If a password is compromised (from a data breach, phishing, or reuse), MFA prevents access without the second factor.
Enable MFA on: - Every AI platform account - Every automation tool (Make, Zapier, n8n) - Your email account (this is the master key — email compromise enables most other account compromises) - Your password manager - Any tool that holds client data
Use an authenticator app (Authy, Google Authenticator, 1Password’s built-in authenticator) rather than SMS-based MFA where possible. SMS codes are vulnerable to SIM-swapping attacks.
6. Recognise AI-Powered Phishing
AI has made phishing attacks significantly more dangerous. Emails that used to be obvious from broken grammar and generic phrasing are now well-written, personalised, and contextually aware.
New patterns to watch for: - Invoices from vendors you use that have slightly wrong details (different account number, slightly different email domain) - Urgent requests from “clients” or “partners” that pressure immediate action - Voice calls that sound like someone you know (voice cloning is now accessible) - Requests to approve payments or change payment details via email
Your defences: - For any financial action triggered by an email, verify via a separate channel (call the person directly, not using the number in the email) - Check the actual sending domain, not just the display name - Build a rule: no payment changes or approvals based solely on an email request - Be especially sceptical of urgency — “you need to do this today” is a social engineering flag
7. Audit Your Data Flows Quarterly
Every quarter, do a 30-minute audit of where your data actually goes:
- What apps are connected to your automation workflows?
- Which AI tools have you granted calendar, email, or file access?
- Are there old app connections you no longer use?
- What data is each tool storing, and do you still agree with those terms?
Revoke access for any tool you no longer use actively. Most people are surprised by how many apps have access to their email or calendar from integrations they set up and forgot about.
What Not to Over-Stress About
Security anxiety can be as damaging as security negligence if it stops you from using AI tools that genuinely help your business. Most solopreneurs face ordinary risks, not sophisticated targeted attacks.
You don’t need to: - Self-host your own AI models - Avoid all cloud-based AI tools - Encrypt every note in Notion - Use a VPN for every AI interaction
The measures above — privacy settings, prompt hygiene, secure API key handling, MFA, and phishing awareness — cover the realistic threat landscape for most solopreneurs. Apply them consistently and you’re significantly more protected than the average solo operator.
