## 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

## Polymer

Polymer positions itself as data security at runtime rather than at rest. As AI agents increasingly operate alongside employees in everyday tools, data can leave an organisation through prompts, generated files, messages, pull requests and commits. Polymer watches those flows across the AI and SaaS ecosystem and applies policies tailored to how each team actually uses AI — grouping human and non-human identities so the same rules govern both.

The platform's core loop is detect, classify, quantify and remediate. It continuously monitors data in motion and at rest, labels sensitive assets according to custom security policies, and scores risk so teams can see shadow AI usage, insider threat activity and misconfigurations. Enforcement happens live: sensitive content can be redacted, file access revoked, or a custom workflow triggered with or without human review. Real-time training and response is built in so employees become part of the defence rather than the gap. Audit logs are mapped to frameworks including HIPAA, SOC 2, CCPA and GDPR for continuous compliance reporting.

Polymer advertises itself as enterprise-ready, with cloud or self-hosted single-tenant deployment, role-based access controls, SOC 2 Type II compliance and integration into existing stacks. Published customer quotes come from security leaders at companies such as RSA, ClickUp, Routefusion, Signify Health and Medly, and the company cites metrics like 99% accuracy in finding sensitive data across SaaS and reductions from eight hours a week of alert triage to near zero.

It is worth noting for any visitor that some blog and library pages on the domain currently carry unrelated low-quality promotional content, which is worth treating with caution. That does not affect the legitimacy of the underlying product, which remains an actively marketed enterprise security platform. Pricing is not published — Polymer sells through demos and direct conversations, so cost depends on scope, deployment model and data volume.

**Pricing & Plans:** Contact for pricing. Polymer does not publish tiers or rates; access is arranged through a demo request and a direct sales conversation, with cost depending on deployment model and scale.

- **Identity-aware detection and response:** Build context-driven policies for your organisation's unique AI usage, then group human and non-human identities to control how each can interact with data.
- **Data detection, classification and labelling:** Continuously monitor data in motion and at rest and label sensitive assets according to your own security policies.
- **Risk quantification:** Reports and risk scores surface shadow AI usage, insider threats and misconfigurations so priorities are clear.
- **Automated runtime enforcement:** Redact sensitive data, revoke file access and trigger custom workflows in real time, with or without human approval.
- **Continuous compliance logging:** Generate audit logs mapped to frameworks such as HIPAA, SOC 2, CCPA and GDPR to support ongoing compliance evidence.

**Strengths:** Focuses on runtime enforcement, not just post-hoc reporting; Covers both human and non-human (AI agent) identities in one policy model; Cloud or self-hosted single-tenant deployment options for security-sensitive buyers; Named customer evidence from recognisable security teams

**Limitations:** No published pricing, so evaluation requires a sales conversation; Enterprise-oriented complexity that likely overwhelms very small teams; Some blog and library content on the domain appears to be unrelated promotional material of low quality
