What is this?

Enterprise AI security stacks network isolation, identity, content safety, audit, and secrets management around agents. AgentNest reference architecture uses VNet, Key Vault, APIM, and defense-in-depth on tools.

Why should you care?

Enterprise RFPs checklist encryption, SOC2, penetration test scope, and data processing agreements before AI go-live.

See it live — copy this example

Paste into an ASP.NET Core 8+ / AgentNest project, then run with dotnet run (set your API keys in user-secrets).

// AgentNest.Api/Program.cs security excerpt
builder.Configuration.AddAzureKeyVault(new Uri(kvUri), new DefaultAzureCredential());
builder.Services.AddSingleton<IChatClient>(sp => /* Azure OpenAI with MI */);
builder.Services.AddAzureClients(b => b.AddSecretClient(new Uri(kvUri)));
app.UseAuthentication().UseAuthorization().UseMiddleware<AiQuotaMiddleware>();

What happened?

Key Vault supplies secrets; managed identity reaches Azure OpenAI; middleware enforces quotas after auth — layered enterprise controls.
Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

Deploy AgentNest.Api to App Service with VNet integration.
Store keys in Key Vault; disable local appsettings secrets in prod.
Enable Azure Defender for Cloud on AI resources.
Add Private Link for Azure OpenAI and Postgres.
Integrate Microsoft Purview for data classification on KB uploads.

Remember

Enterprise AI security layers identity, network, secrets, and content safety. AgentNest uses Key Vault, MI, APIM, and audit together. Pen-test agent endpoints and tool paths, not just login.
