Automated Reasoning checks are generally available as of August 6, 2025, and support EU AI Act compliance by converting risk criteria into verifiable guardrails.
Use cases include PwC’s Regulated Content Orchestrator (RCO) for content and brand compliance, and utility outage management with severity-based verification workflows.
The alliance emphasizes responsible AI as a path to faster, safer AI-driven innovation without compromising accuracy, security, or compliance. AWS and PwC note the strategic value of reasoning in rapid AI adoption.

Context and background

In a globally competitive environment where speed and innovation outpace traditional safeguards, organizations increasingly deploy generative AI at scale while balancing accuracy, security, and compliance. PwC and AWS are jointly developing reasoning checks that combine PwC’s deep industry expertise with Automated Reasoning capabilities embedded in Amazon Bedrock Guardrails. Automated Reasoning is a branch of AI focused on algorithmic search for mathematical proofs; when applied to Bedrock Guardrails, these checks encode knowledge from policy documents into formal logic to validate whether AI outputs are possible under defined rules. The checks produce findings that indicate alignment with policy, reveal ambiguities in content, and offer suggestions on removing unsupported assumptions. The capabilities were highlighted by PwC leadership at AWS Re:Invent 2024 and are positioned to help customers deploy AI at speed while maintaining trust. In practice, this approach targets highly regulated sectors such as pharmaceuticals, financial services, and energy. PwC has developed a practical framework to address EU regulatory requirements by transforming the EU AI Act’s risk classification and governance requirements into guardrails that can be consistently applied, monitored, and auditable. The guardrails workflow yields auditable artifacts and automated verification that supports expert human judgment. The collaboration also centers on PwC’s Regulated Content Orchestrator (RCO), a globally scalable, multi-agent capability powered by a core rules engine. RCO automates medical, legal, regulatory, and brand compliance and served as an early adopter of Bedrock Automated Reasoning as a secondary validation layer in marketing content generation. The result is accelerated content creation and review while strengthening compliance controls. In addition to content governance, Automated Reasoning checks have practical applications for operational resilience. For example, utility outage management uses Bedrock Guardrails to generate standardized procedures from regulatory guidelines (NERC and FERC) and verify AI-produced outage classifications. A cloud-based architecture enables severity-based workflows that guide dispatch decisions: normal outages target a 3-hour response, medium severity triggers expedited dispatch, and critical incidents activate emergency procedures with proactive messaging. As AI adoption grows, the AWS–PwC alliance continues to emphasize responsible AI with automated reasoning as a foundational safeguard to improve trust and enable scalable innovation across industries.

“In a field where breakthroughs are happening at incredible speed, reasoning is one of the most important technical advances to help our joint customers succeed in generative AI,” PwC Global CTIO Matt Wood noted at AWS Re:Invent 2024. The collaboration seeks to combine PwC’s domain expertise with AWS technologies to transform AI-driven innovation while preserving accuracy, security, and compliance. The following sections outline the three groundbreaking use cases PwC and AWS explored and how automated reasoning integrates into Bedrock Guardrails.
