## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Proof&Trust

Proof&Trust targets the supply-chain obligation created by NIS2 Article 21(2)(d), which makes the security posture of direct suppliers the responsibility of the buying organisation. Instead of chasing annual questionnaires across document stores, the platform ingests contracts, vendor masters and document repositories, then automatically validates the authenticity, validity and scope of certificates, attestations, SBOMs, penetration-test reports and policies.

Each artifact receives an evidence-grade score based on completeness, recency, source trust and control coverage. These scores roll up into a vendor risk index that is recalculated continuously rather than frozen at an annual snapshot, and vendors are auto-classified into tiers — critical/high, important/medium and baseline/low — according to dependency, concentration and evidence quality. Tier changes are timestamped, traceable to the underlying evidence, and exportable as audit-ready proof, so a new CVE or expired certificate can move a vendor up the risk ladder within minutes.

The vendor says a sample portfolio can be scored in under 30 minutes with no integration and no credit card, in an EU-hosted environment with data residency and encryption in transit and at rest. Reporting is mapped across all ten NIS2 Article 21(2) measures, and the platform also supports Article 23 incident-notification drafting with 24-hour early-warning timing. The offering is aimed at compliance, security and procurement teams in regulated sectors such as banking, energy, healthcare, telecom and the public sector.

**Pricing & Plans:** Published annual tiers in euros (excluding VAT). Basic: €1,999/year for up to 20 vendor assessments. Professional: €4,900/year for up to 100. Enterprise: €9,900+/year for up to 300, with custom branding, a read-only auditor account, API export and SLA. Larger portfolios and private/on-prem deployments are quoted individually. A free sample assessment and a free trial are offered.

- **Evidence ingestion and validation:** Connects contracts, vendor masters and document stores, then verifies the authenticity, validity and scope of certificates, attestations, SBOMs, pen-test reports and policies.
- **Artifact and vendor scoring:** Scores each artifact on completeness, recency, source trust and control coverage, then rolls the results into a continuously recalculated vendor risk index.
- **Continuous NIS2 tiering:** Auto-classifies vendors into critical, important and baseline tiers by dependency, concentration and evidence quality, re-tiering the moment evidence changes.
- **Audit-ready reporting:** Produces cited, exportable evidence trails mapped to all ten NIS2 Article 21(2) measures, plus Article 23 incident-notification drafting with 24-hour early-warning timing.
- **No-integration onboarding:** Drop in a sample of supplier evidence and receive a scored, tiered portfolio in under 30 minutes, with NDA available and EU-hosted data residency.

**Strengths:** Published euro pricing makes budgeting straightforward, unlike many compliance platforms; Continuous scoring and re-tiering beats an annual questionnaire snapshot when risk changes mid-year; No integration is required to get a first scored portfolio, and a free sample assessment lowers the trial risk; EU-hosted with data residency and explicit mapping to all ten NIS2 Article 21(2) measures

**Limitations:** Focused squarely on NIS2, so organisations outside its scope get less out of the tiering model; Assessment caps per tier (20/100/300) mean very large vendor estates need a custom quote; It is a newer platform, so it lacks the long public track record of established GRC suites
