Overview
Enterprises are deploying autonomous AI agents, but projects stall before production because agentic security feels like an un-instrumented black box. Agentic threats multiply rather than add: a single hallucination becomes an irreversible action, poisoned memory persists across sessions, and one compromised node can cascade across an agent cluster. Cloud platforms provide the infrastructure, but not the safety instrumentation agentic code requires. Virtusa's Agentic Governance & Security accelerator bridges that gap with a five-layer reference architecture mapped to AWS-native services - Amazon Bedrock Guardrails and Agent Core, AWS Verified Permissions, Step Functions, Secrets Manager, CloudTrail and Guard Duty - wrapped in governance and cross-cutting observability. Delivered as an assessment-led engagement, it takes agentic workloads from sandbox to production with immutable audit trails, real-time circuit breakers, and alignment to the EU AI Act, DORA and NIST AI RMF.
Highlights
- Five-layer reference architecture mapped end-to-end to AWS-native services: Amazon Bedrock Guardrails for safety, Bedrock Agent Core for runtime, memory, identity and observability, AWS Verified Permissions for policy enforcement, Step Functions for orchestration constraints, Secrets Manager for just-in-time credentials, and CloudTrail with S3 Object Lock plus Guard Duty for immutable audit and behavioral monitoring - covering every layer from agent application down to infrastructure.
- Purpose-built controls for threats traditional security misses: real-time circuit breakers stop a hallucination before it becomes an irreversible action; strict MCP tool gates and isolated memory tiers block prompt injection and cross-session memory poisoning; and governed non-human identities with zero standing privilege and continuous behavioral monitoring contain the blast radius across dynamic agent graphs
- Regulatory readiness delivered as deterministic software controls: audit trails, classification boundaries and human-oversight gates aligned to the EU AI Act, DORA and UK GDPR, built to OWASP Agentic Top 10, NIST AI RMF 1.0 and ISO/IEC 42001. Proven through a live reference implementation with hash-chained audit logging, Open Telemetry transaction tracing, and cost and performance dashboards.
