## Fiddler AI

Fiddler AI presents itself as an AI Control Plane — a system of trust that spans the whole lifecycle of enterprise AI, from the creation layer where coding agents write software to the production layer where agents run the business. Rather than treating observability, evaluation, security and governance as four separate products, Fiddler consolidates them so teams answer one question: are my agents working, and are they working safely?

The platform covers two model types. For predictive ML it offers traditional model monitoring, drift detection and explainability, helping data science teams keep accuracy high and diagnose regressions. For generative and agentic systems it layers continuous evaluation, agentic observability and policy enforcement on top, so you can trace every agent decision, evaluate quality against your own criteria, and block or redact unsafe content inline.

A distinguishing technical bet is Fiddler Centor Models — secure, cost-efficient models that run guardrails and evaluations in-environment rather than calling an external LLM API for every trace. The vendor claims this reduces evaluation TCO by up to 98% versus foundation-model-based evaluation, and reports sub-80ms enforcement latency and 99% precision blocking jailbreak attempts in production. Governance features maintain a living inventory of connected agents and record each enforcement decision for audit evidence, targeting GRC standards and emerging AI regulations.

**Pricing & Plans:** Contact for pricing. Fiddler publishes a Pricing Plans page with a 'Contact Sales' route instead of fixed rates; the cost depends on deployment scope, agent and model volume, and whether you deploy in SaaS, a VPC or AWS GovCloud.

- **Agentic and ML observability:** See the performance of every agent and predictive model in a single pane of glass, with every action, token and dollar traceable by user and team.
- **In-environment guardrails and evaluations:** Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.
- **Inline policy enforcement:** Detects and redacts PII, PHI and secrets on the same request path — before a prompt reaches the model and before a response reaches the developer — with sub-80ms latency.
- **Auditable AI governance:** Keeps a living inventory of every connected agent and records each enforcement decision, with who triggered it and what happened, ready for GRC and AI regulation audits.
- **Deployment flexibility:** Runs in SaaS, your VPC or AWS GovCloud, with over 100 predefined metrics plus any custom metric and integrations across AWS, Google Cloud, NVIDIA, Databricks and Datadog.

**Strengths:** Single platform spanning both the code-creation layer and the production layer; Centor Models cut evaluation cost dramatically by removing external LLM API calls per trace; Inline enforcement detects and redacts PII, PHI and secrets with reported sub-80ms latency; Auditable governance with a living agent inventory maps directly to GRC and AI regulation needs

## Oak

Oak describes itself as an AI-native identity operating system, born complete rather than retrofitted for AI or assembled through acquisitions. Its core argument is that AI has pushed identity to the frontline of cybersecurity: identity data is fragmented across tools, reviews are rule-based and periodic, service accounts and AI agent behavior create blind spots, and teams often can see risks without being able to remediate them. Oak's answer is to own the full stack, from seeing every identity in an environment to controlling what each one can do based on intent and context.

The foundation is an Identity Intelligence Layer that acts as one live source of truth — a single data model and graph for the whole identity security stack. On top of it, Oak governs human identities, machine and service accounts, and AI agents, so autonomous agents can be inventoried with accountable owners, effective permissions, and a record of who they act for. Because Oak is positioned as "connect any," it aims to integrate with whatever environments an organization already runs and adapt as new systems are added.

For enterprises that want hands-on help, Oak offers White Gloves: a dedicated identity services team that builds, migrates, and manages identity programs end to end, including enterprise system integration, rapid deployment, and customized solutions. The company targets enterprise scale, with the Oak Promise offering implementation hours and all connectors to qualified Fortune 500 organizations.

**Pricing & Plans:** Contact for pricing. Oak does not publish public self-serve tiers; pricing is quoted to qualified organizations. The company advertises an Oak Promise (up to 500 free human hours of White Gloves work and all connectors included) available to qualified Fortune 500 enterprises.

- **Identity Intelligence Layer:** A centrally owned identity platform where every identity is discovered, seen, and governed from one live graph rather than scattered tool-specific lists.
- **Agentic identity governance:** Inventory and govern autonomous AI agents and MCP servers as identities, with owners, scoped permissions, and records of who they act for.
- **Connect-any integrations:** Connect to the identity, security, and enterprise systems you already run, aiming for one data model instead of a patchwork of acquired tools.
- **White Gloves managed services:** A dedicated services team that builds, migrates, and manages identity programs end to end, from discovery through ongoing management.
- **Context-aware, continuous governance:** Go beyond quarterly, rule-based reviews with a live source of truth that reflects what is happening across the environment now.

**Strengths:** One live identity graph as a single source of truth instead of fragmented tools; Covers human, machine, and AI agent identities in one platform; White Gloves services team handles implementation, migration, and management; Connect-any integrations aim to fit existing enterprise environments

**Limitations:** Pricing requires contacting sales rather than self-serve checkout; Designed for enterprises, so smaller teams may find the scope heavy; Value depends on connecting Oak to your existing identity and security stack; Newer category, so buyers should validate fit through a demo
