Private AI Solutions

Private AI Solutions — On-Premise AI That Never Leaves Your Network

Every query you send to a cloud AI provider leaves your security perimeter, traverses infrastructure you do not control, and may be retained for model training you did not authorize. For organizations handling controlled unclassified information, protected health information, attorney-client privileged data, or trade secrets, this is unacceptable. Petronella Technology Group, Inc. deploys private AI solutions that run entirely on your infrastructure or ours—with zero cloud dependency, complete data sovereignty, and the compliance controls that CMMC, HIPAA, and SOC 2 auditors demand. We run our own private AI infrastructure. We know exactly how to build yours.

Complete Data Sovereignty

Your data never leaves your network. Private AI models process queries, generate responses, and store results entirely within your security perimeter. No external API calls, no cloud processing, no data retention by third-party vendors. You maintain absolute control over every byte of information your AI system touches.

Air-Gapped Deployment

For defense contractors, intelligence agencies, and critical infrastructure operators, we deploy AI systems on air-gapped networks with zero internet connectivity. Models run entirely offline after initial deployment, processing classified and sensitive data without any external communication pathway that adversaries could exploit.

CMMC L2 Compliant

Private AI infrastructure satisfies CMMC Level 2 requirements for handling controlled unclassified information. Access controls, audit logging, encryption at rest and in transit, incident response procedures, and configuration management are built into the architecture—not bolted on for certification.

No Vendor Lock-In

Open-source models running on hardware you own or control means you are never dependent on a single AI vendor's pricing, policies, or continued existence. When better models emerge, you upgrade on your schedule. When regulations change, you adapt without renegotiating SaaS contracts or migrating away from proprietary platforms.

Why Private AI Is No Longer Optional for Regulated Organizations

The Data Sovereignty Crisis of Cloud AI

The adoption of cloud-based AI services has created a data sovereignty crisis that most organizations have not fully reckoned with. Every query sent to OpenAI, Anthropic, Google, or any cloud AI provider travels across networks you do not control, is processed on servers in data centers you cannot audit, and is subject to data retention policies you cannot enforce. For organizations in Raleigh, North Carolina and across the nation handling CUI under CMMC, PHI under HIPAA, financial data under SOC 2, or legally privileged information, this data exposure is not a theoretical risk—it is a compliance violation waiting to be discovered during an audit.

Documented Risks of Cloud AI Vendor Policies

The cloud AI vendor landscape compounds the problem. Major providers have repeatedly changed their data retention and training policies, sometimes retroactively. Data that was supposedly not retained for training has been used for model improvement. API logs have been stored longer than disclosed. Employee access to customer queries has been broader than documented. These are not hypothetical concerns—they are documented incidents that have driven regulatory scrutiny and enterprise risk reassessments. For organizations where data exposure has legal, regulatory, or national security implications, the risk profile of cloud AI is simply too high.

Complete Data Control With Private Deployment

Private AI solves this problem completely. When Petronella Technology Group, Inc. deploys a private AI solution, the large language model runs on infrastructure you control—either your own servers, our dedicated managed infrastructure, or colocated hardware in auditable facilities. Your data enters the model, generates a response, and is logged according to your retention policies. No external API calls. No data leaving your perimeter. No third-party vendor with access to your queries. The model weights, configuration, and deployment are under your control, and you can verify this through standard security assessments that are impossible with opaque cloud services.

We Run Our Own Private AI Infrastructure

We understand private AI deployment because we operate it ourselves. Petronella Technology Group, Inc. runs its own private AI infrastructure—including a 96-core AMD EPYC server with three NVIDIA RTX PRO 6000 GPUs providing 288GB of combined VRAM, a 24-core AMD Zen 5 workstation with an RTX 5090 and 256GB of DDR5 RAM, and NVIDIA DGX Spark clusters. Our fleet runs production AI workloads on vLLM, llama.cpp, and Ollama serving open-source models including Meta Llama, Mistral, and specialized fine-tuned variants. We host our own Nextcloud HA cluster with DRBD replication and LUKS encryption for file collaboration—no Microsoft 365 or Google Workspace dependency. This is not a sales pitch about what we could build for you. This is a description of what we already run every day.

The Improving Economics of Private AI

The economic case for private AI has improved dramatically. Open-source models have reached performance parity with commercial alternatives for most business applications. GPU hardware costs have decreased while VRAM capacities have increased. Fine-tuning techniques like LoRA and QLoRA enable domain adaptation on a single high-end GPU. The result is that a dedicated private AI deployment now costs less than multi-year SaaS subscriptions for organizations with moderate to heavy AI usage—while providing complete data control, zero per-query costs, and hardware assets that retain residual value. Our LLM fine-tuning services detail how we adapt open-source models for private deployment.

Private AI for Defense Contractors and CMMC Compliance

Why Cloud AI Complicates Your CMMC Boundary

Defense contractors handling controlled unclassified information face a specific challenge: CMMC Level 2 requires that CUI is processed, stored, and transmitted only within authorized environments with documented security controls. Cloud AI services—even those offering CMMC-compliant tiers—introduce third-party risk that complicates your authorization boundary, requires additional vendor assessments, and creates data handling dependencies outside your direct control. Private AI eliminates this complexity entirely by keeping all AI processing within your existing CMMC boundary.

CMMC L2 Controls Across All 14 Practice Domains

Petronella Technology Group, Inc. builds private AI deployments for defense contractors that satisfy CMMC L2 requirements across all 14 practice domains. Access controls enforce least privilege on model endpoints. Audit logging captures every query, response, and administrative action with tamper-evident timestamps. Encryption protects data at rest using AES-256 and in transit using TLS 1.3. Configuration management tracks every change to model weights, system prompts, and deployment parameters. Incident response procedures cover AI-specific scenarios including prompt injection attempts, data exfiltration via model outputs, and adversarial input attacks. Our CMMC compliance services and CMMC compliance guide provide comprehensive context on the regulatory landscape.

Air-Gapped Deployment for Classified Environments

Air-gapped deployment is available for organizations that require it. After initial model deployment and configuration, the AI system operates entirely offline with no network connectivity to external systems. Model updates are delivered via physically transported media following your organization's existing procedures for introducing software to isolated networks. This deployment model is essential for organizations handling classified information or operating in environments where any external network connectivity represents an unacceptable risk.

Hosting includes monitoring, maintenance, model updates, and SLA-backed availability guarantees. See our AI inference hosting services for details.

Our Private AI Deployment Process

Requirements & Security Assessment

We assess your compliance framework, data classification levels, user base, performance requirements, and infrastructure capabilities. This phase determines whether deployment targets your existing hardware, new on-premise servers, colocated infrastructure, or our managed hosting. Security requirements are mapped to specific controls that will be implemented in the deployment architecture.

Model Selection & Infrastructure Design

We benchmark candidate open-source models against your specific use cases, select the optimal model and quantization strategy, specify hardware requirements, and design the deployment architecture including networking, storage, authentication, and monitoring. For organizations requiring fine-tuning, we prepare training data pipelines and schedule GPU time on our infrastructure.

Deployment & Hardening

We deploy the AI system, configure security controls, implement monitoring, run performance benchmarks, and conduct security assessments. Access controls, audit logging, encryption, and compliance documentation are verified before the system accepts production traffic. User training ensures your team can interact with the system effectively and understand its capabilities and limitations.

Operations & Continuous Improvement

Ongoing monitoring tracks performance, security events, and usage patterns. We update models as better open-source alternatives emerge, expand capabilities based on user feedback, and maintain compliance documentation as regulations evolve. Quarterly reviews assess whether the deployment is meeting performance targets and identify opportunities to extend private AI capabilities to additional use cases.

Private AI Solutions FAQs

How do private AI models compare to cloud AI services like ChatGPT?

Open-source models have reached performance parity with commercial cloud APIs for most business applications. For domain-specific tasks, fine-tuned private models often outperform generic cloud services because they are trained on your specific terminology and data. The primary trade-off is that private models require GPU hardware, while cloud APIs spread hardware costs across millions of users. For organizations with compliance requirements, moderate to heavy AI usage, or data sovereignty needs, private AI is both more capable and more cost-effective long term.

What hardware is needed for private AI deployment?

Requirements depend on model size and concurrent users. Small models for focused tasks run on a single workstation-class GPU with 24GB VRAM. Mid-range deployments serving 10-50 concurrent users typically need 48-96GB of VRAM across one or two GPUs. Enterprise deployments serving hundreds of users require multi-GPU servers. We specify exact hardware configurations based on your performance requirements and budget, and can start with minimal hardware and scale as usage grows.

Can private AI work on an air-gapped network?

Yes. This is one of the primary advantages of private AI over cloud services. Once the model and serving infrastructure are deployed, no internet connectivity is required. The system operates entirely offline, processing queries and generating responses using local compute resources. Model updates are delivered via physical media following your cross-domain transfer procedures. We package complete deployments—including all dependencies—for isolated installation.

Is private AI compliant with CMMC Level 2?

Private AI is the most straightforward path to CMMC-compliant AI. By keeping all processing within your existing CMMC boundary, you avoid the third-party risk assessment, vendor authorization, and data handling complications of cloud AI services. We implement all required controls—access management, audit logging, encryption, configuration management, incident response—and produce the documentation your C3PAO assessor needs to validate compliance.

How much does private AI infrastructure cost?

Hardware costs range from a few thousand dollars for a single GPU workstation deployment to six figures for multi-GPU server clusters serving enterprise workloads. Deployment, configuration, and security hardening are project-based fees. The total cost of ownership over three to five years is typically lower than equivalent cloud AI API spending for organizations with moderate to heavy usage, with the added benefits of zero per-query costs, complete data control, and hardware asset ownership.

Can we start small and scale up later?

Absolutely. Most organizations start with a single GPU server running a quantized model for a specific use case, then expand as they validate the value and identify additional applications. The architecture we deploy is designed for horizontal scaling—adding GPUs, servers, or model variants as your needs grow. You can also start with our managed hosting and migrate to on-premise hardware once you have validated the technology and justified the capital investment.

Which AI models work best for private deployment?

The best model depends on your use case, available hardware, and performance requirements. Meta Llama 3 models excel at general-purpose tasks. Mistral and Mixtral models offer strong performance in smaller form factors. Specialized models exist for code generation, medical text, legal analysis, and multilingual applications. We benchmark multiple candidates against your specific data and select based on measured performance, not marketing claims. Fine-tuning further improves accuracy for domain-specific applications.

Do you manage the private AI system after deployment?

Yes. We offer managed services for private AI including continuous monitoring, model updates, performance optimization, security patching, and user support. For on-premise deployments, we provide remote management through secure VPN connections or on-site support depending on your security requirements. For managed hosting, operations are included in the service. We also train your internal team to handle day-to-day operations if you prefer self-management.
