The AI Privacy Paralysis That's Costing SMEs Everything

What? Deploys AI models on your own device, enabling private, custom chat-based workflows.

Example: Ollama + Open WebUI running in Docker on laptops for individual use.

When? This works when you need immediate privacy for simple chat based tasks but don't have technical resources.

Cost estimates:

• Setup: $0-650 (per person if hardware upgrade required)
• Ongoing: $0/month
• Time investment: 8-12 hours initial setup and learning

Difficulty: Quick start (1-2 weeks)

Considerations

• Limited capability that won't scale beyond personal productivity
• Models less capable than cloud based one
• Need decent laptop hardware to run models
• Requires some technical proficiency to run models locally
• Works well for fixing individual productivity rather than business transformation

What: Run AI models entirely on your own physical hardware, managed and secured by your team, with no external cloud dependencies.

Example: vLLM running a GPT-NeoX LLM model on a local GPU rack sat behind a Caddy proxy.

When? You have high-security requirements, substantial technical expertise, and budget for complete data control.

Cost estimates:

• Setup: $19,000-65,000 (servers, GPUs, networking, installation)
• Ongoing: $2,600-6,500/month (power, cooling, maintenance, staff time)
• Time investment: 2-3 months full deployment

Difficulty: Major project (3+ months) + ongoing technical maintenance

Considerations

• Expensive upfront hardware investment (GPUs, servers, networking)
• Requires dedicated technical team for setup and ongoing maintenance
• Complex infrastructure management and security responsibilities
• Significant ongoing costs for power, cooling, and updates
• Maximum privacy and control but substantial resource commitment
• Best for organisations where zero external data exposure is non-negotiable

What: Run AI models on dedicated cloud resources that you control and configure, not shared/public SaaS.

Example: Deploy LLMs like Llama 3 using vLLM on dedicated AWS EC2 instances with Inferentia/Trainium chips for scalable, managed inference. Example AWS deployment guide

When? You need control and scalability, but want to avoid on-premise hardware and leverage cloud flexibility.

Cost estimates:

• Setup: $0-2,600 (cloud integration, configuration)
• Ongoing: $650-3,900/month (cloud compute, storage, bandwidth)
• Time investment: 1-3 weeks setup and scaling

Difficulty: Medium complexity (1-2 months) + ongoing technical maintenance

Considerations

• Lower upfront cost than on-premise, but ongoing cloud spend
• Still requires technical expertise for secure configuration and management
• Data remains under your control, but is hosted offsite
• Easier to scale up or down as resource needs change
• Vendor lock-in and cloud compliance still need to be managed

EU-hosted providers offering data residency compliance and GDPR-first solutions. This suits EU businesses with strict regulatory requirements.

Examples:

• Aleph Alpha: A sovereign, transparent EU-based provider focused on data protection, explainability, and compliance for critical industries and the public sector.
• OpenAI European Data Residency: Mainstream LLMs with new options for processing and storing data exclusively within the EU, helping address GDPR and client data residency requirements. Note: This is typically part of OpenAI's Enterprise plan, and specific pricing requires contacting their sales team.

Cost estimates:

• Setup: $0-2,600 (integration and compliance review for general EU-compliant cloud services)
• Ongoing: $260-2,600/month (depending on usage and provider; OpenAI Enterprise pricing will vary and requires direct inquiry)
• Time investment: 2-4 weeks setup and compliance verification

Difficulty: Medium complexity (1-2 months)

Considerations

• Best for when regulatory requirements are your primary concern.
• Ongoing vendor management and contract review required
• User access controls and data handling policies within the cloud service still need active management.
• Monitoring API usage, costs, and any provider-side changes is necessary.
• Regularly verify that the service continues to meet your compliance obligations.

What? Data obfuscation combined with cloud APIs

Example: N8N jobs running data pipelines to sanitise data before calling cloud based LLM models

When? You want cloud performance with enhanced data protection and have the expertise for careful implementation.

Cost estimates:

• Setup: $3,900-10,400 (sanitisation system development)
• Ongoing: $390-1,950/month (cloud costs + monitoring tools)
• Time investment: 4-6 weeks development and testing

Difficulty: Medium complexity (1-2 months) + ongoing technical maintenance

Considerations

• Requires technical expertise to implement data sanitisation properly
• Need robust obfuscation processes to protect sensitive information
• Ongoing management of privacy controls and monitoring
• More complex than standard cloud but less than full local infrastructure
• Good balance of performance and privacy for technically capable teams
• Success depends on quality of your data protection implementation

What? Standard cloud APIs with strong contracts and monitoring systems. Choose this when speed of deployment matters more than privacy concerns. Fastest implementation but requires ongoing risk management.

Example: Direct OpenAI, Anthropic, Gemini API usage in your workflows

Cost estimates:

• Setup: $0-1,300 (integration and monitoring setup)
• Ongoing: $130-1,300/month (API costs based on usage)
• Time investment: 1-2 weeks integration

Difficulty: Quick start (1-2 weeks)

Considerations

• Fastest time to market with immediate access to cutting-edge capabilities
• Relies on vendor privacy policies and data handling commitments
• Requires ongoing contract negotiation and risk monitoring
• Cost-effective for high-volume usage but potential vendor lock-in
• Suitable when competitive speed outweighs data sovereignty concerns
• Regular compliance audits needed to maintain oversight
• Privacy controls available: opt out of data training, enterprise agreements with enhanced protections, and API-only access to avoid chat history retention
