Sentinel SCA is an execution-security and admissibility layer for autonomous systems. It sits between autonomous reasoning and consequential action, independently checking identity, authority and policy before an action is allowed to execute. Sentinel uses signed decisions, short-lived...

As answered by people managing Sentinel SCA and Diffyn.
Sentinel SCA's answer
Sentinel SCA focuses on a specific gap in AI-agent infrastructure: the difference between what an agent is capable of doing and what it is actually authorized to do at the moment of execution. Sentinel evaluates consequential actions before execution, binds authorization to the governed action, and requires the execution boundary to verify that authority before allowing the side effect. The core principle is: Capability ≠ Authority.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Sentinel SCA's answer
Sentinel SCA is designed for organizations that need more than AI observability, identity, or post-action audit logs. Its focus is pre-execution governance: determining whether a specific action is authorized before it becomes real, then preserving evidence around that decision and execution boundary. Sentinel should be evaluated alongside alternatives based on whether that pre-execution authority layer is important to the customer’s use case.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
Sentinel SCA's answer
Sentinel SCA is primarily built using Python and FastAPI, with Redis for runtime state and replay controls, Docker for deployment and isolation, and Ed25519 cryptographic signatures for authorization evidence. The platform also uses deterministic validation, action digests, executor-side verification, fail-closed control paths, and tamper-evident audit records.
Diffyn's answer:
React, Next.js, POSTGRESQL
Sentinel SCA's answer
Sentinel SCA is primarily built for enterprises, startups, AI infrastructure teams, security teams, compliance teams, and developers deploying autonomous or semi-autonomous AI agents that can take consequential actions in real systems. Relevant environments include finance, enterprise SaaS, infrastructure, operations, healthcare, and other regulated or high-impact workflows.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Sentinel SCA's answer
Sentinel SCA came from a simple observation about how human organizations already work: being capable of doing something does not automatically give someone permission to do it.
Employees operate within roles, policies, approval levels, limits, and responsibilities. As AI agents began moving from conversation into real-world execution, the same separation between capability and authority was missing.
Sentinel SCA was created to implement that principle for autonomous systems: before an AI agent performs a consequential action, verify whether that exact action is authorized under the applicable policy and constraints.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
Sentinel SCA's answer
Sentinel SCA is currently in early commercial validation and pilot development. No major production customers are being publicly claimed at this stage.
