What Sondera does
Sondera is an early-stage software company that provides AI agent governance infrastructure for organizations deploying autonomous AI agents to production. Its platform targets the 'Agent Layer'—the visibility gap that exists after a prompt is issued—where current developer tools stop but agents continue to act autonomously. The company's product consists of two integrated components: a Runtime Harness that intercepts and evaluates agent actions in real time using Cedar policy language for deterministic policy-as-code enforcement, and an Evaluation Harness that runs adversarial simulation and stress-testing against synthetic trajectories. Sondera also offers an open-source Python SDK (sondera-harness) with native middleware/plugin/hook integrations for LangGraph, Google ADK, Strands, and OpenClaw, plus 103 pre-built Cedar policies organized into three security packs.
The company's go-to-market is hybrid: a product-led motion through free local evaluation via CedarPolicyHarness, an open-source SDK on GitHub and PyPI, and a developer Slack community; combined with an enterprise field-sales motion via a 'Book a Demo' CTA on the website. Revenue derives from a subscription model with monthly and annual billing for the cloud platform, with self-hosted/VPC deployment options for regulated buyers. Pricing is not publicly disclosed. Target customers are enterprise AI agent deployers who need real-time controls and audit-ready evidence for ISO 42001 and SOC 2 compliance, with a secondary vertical focus on defense and national security environments. The company is headquartered in Philadelphia, was founded in 2025, has 1-10 employees, and operates as Sondera, Inc. (Delaware C-corp) with no disclosed funding rounds to date. Its most notable strategic move is its June 2026 founding membership in the AI Proving Grounds Consortium (AIPGC), alongside Corelight, Dropzone AI, SCYTHE, and SimSpace.

Sondera product offering
Product offeringCore offering
Sondera provides a cloud-based AI control and governance platform for autonomous agents. It delivers real-time guardrails, policy enforcement, full observability, and evaluation tooling so enterprises can safely deploy AI agents in production. The offering is delivered as a managed SaaS platform with an open-source Python SDK for local development.
Product overview
Sondera offers a unified AI agent governance platform consisting of two integrated components: the Runtime Harness for real-time oversight and the Evaluation Harness for simulation. The platform is accessible via Sondera Harness, an open-source Python SDK that provides deterministic policy evaluation using Cedar policies. Two deployment modes are available: CedarPolicyHarness for local, dependency-free evaluation, and SonderaRemoteHarness for cloud-connected team deployments with centralized policy management and audit logging. The product integrates natively with major agent frameworks (LangGraph, Google ADK, Strands, OpenClaw) and supports custom agent implementations via API.

- Robust Intelligence (now Cisco AI Defense): Robust Intelligence, acquired by Cisco, provides AI firewall and continuous model validation. Comparable to Sondera in addressing adversarial inputs and runtime enforcement, though more focused on model-level than agent-action-level control.
Broad incumbents
- Cloudflare AI Gateway: Cloudflare provides AI security features including prompt injection detection via AI Gateway and Cloudflare One. Incumbent with massive distribution that could expand into agent-layer governance to compete with Sondera.
- Microsoft Azure AI Content Safety: Microsoft Azure AI Content Safety provides prompt shield, jailbreak detection, and content filtering for Azure-hosted AI applications. Broad incumbent offering that overlaps with Sondera on prompt injection defense and policy enforcement.
- AWS Bedrock Guardrails: AWS Bedrock Guardrails provides native content filtering and topic controls for agents built on Bedrock. A broad incumbent that competes on convenience and bundled pricing for AWS-native deployments, though more limited in cross-framework support than Sondera.
Emerging players
- Mindgard: Mindgard offers AI security testing and red-teaming for AI models and agents. Partial overlap with Sondera's Adversarial Simulation component and broader agent security posture.
- Pillar Security: Pillar Security focuses on securing AI applications and agents, addressing risks like prompt injection and data leakage. Smaller, emerging player competing for similar early enterprise customers as Sondera.
