Shaping the Future of Technology from historic Newport, KY.
Azure & Microsoft AI Security Solutions
Secure the systems, models, and data flows that power enterprise AI. We protect AI workloads, applications, and custom agents across Microsoft Azure and Microsoft 365 with zero-trust architecture.
What Is Enterprise AI Security?
Enterprise AI security is the technical practice of designing, defending, testing, and monitoring artificial intelligence workloads, foundational models, data retrieval pipelines, and autonomous agents against malicious exploitation and unauthorized data leakage. It addresses AI-specific vulnerabilities—such as direct and indirect prompt injection, jailbreaking, model poisoning, unauthorized retrieval exfiltration, and excessive agent tool authority—by implementing defense-in-depth controls across cloud networks, identity systems (Entra ID), data governance (Purview), and continuous red-team testing.
Adversarial AI Red Teaming Sprints
Traditional firewalls cannot detect prompt injection or agent jailbreaking. We simulate sophisticated adversarial attacks in a controlled sandbox before your AI touches production data.
- Indirect Prompt Injection: Test whether malicious third-party emails or PDFs can hijack your model's logic.
- Data Exfiltration Testing: Attempt to force models into revealing confidential system prompts or training records.
- Agent Authority Abuse: Verify that tool-calling agents cannot be coerced into unauthorized database edits or financial transfers.
- University of Cincinnati Research: Methodologies backed by active academic research into trustworthy AI grounding.
The 7-Layer AI Workload Security Matrix
Comprehensive technical protection from model weights to user interfaces:
| Security Layer | Vulnerability Prevented | Nexigen Technical Control |
|---|---|---|
| 1. Architecture | Trust boundary violations | AI Threat Modeling matrix (STRIDE-AI) & zero-trust data-flow mapping. |
| 2. Identity & Access | Rogue agent actions & stolen keys | Microsoft Entra ID managed identities for agents & scoped OAuth permissions. |
| 3. Network Isolation | Public internet endpoint exposure | Azure OpenAI Private Endpoints & Virtual Network (VNet) injection. |
| 4. Data Protection | Confidential records surfacing in prompts | Microsoft Purview sensitivity tags & real-time cryptographic DLP filters. |
| 5. Model Defense | Prompt injection & jailbreaking | Azure AI Content Safety prompt shields & output schema validation. |
| 6. Agent Guardrails | Unauthorized transactional execution | Hard approval gates (HITL), rate limiting, and execution sandboxes. |
| 7. Observability | Silent failures & adversarial probes | Microsoft Sentinel AI connectors, LLM telemetry traces, and alert playbooks. |

The Nexigen Help Desk is always accessible to troubleshoot minor issues that might arise, while the sales and experienced tech staff that really understand our firm’s existing systems and needs are also just a phone call away.
Joseph Schimpf, Schimpf, Ginocchio, Kehres & Clark, LLC, Cincinnati, OH
There have been many positive changes since Nexigen started serving our IT needs, but the most noticeable change is the near-instant service any day, any time. And it’s not just answering the phone, they are almost always able to fix my problem very quickly. It’s like having an IT guy in every cubicle. The instant response and fast resolution of issues it what sets Nexigen apart.
Curtis Edwards, ThreeBond International, West Chester, OH
Nexigen lets us focus on our core business instead of worrying about managing our IT infrastructure. Also, they were able to quickly recover from a ransomware attack quickly and efficiently with very little interruption to our operations. The team is responsive and knowledgeable. I always get through promptly when support is required.
