About

Astah System Safety is a model-based safety analysis tool for safety-critical systems, developed by Change Vision, Inc. It combines SysML modeling with STAMP/STPA hazard analysis, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF in one tool. Safety analyses are linked to the system model, so control structures, hazards, and safety arguments stay traceable to requirements and architecture. It is used by safety engineers in automotive, aerospace, and embedded systems, including safety-case work for standards such as ISO 26262. AI Chat Copilot works with your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service, and a local MCP server connects external AI agents to your models. Models can be exchanged through XMI and with Cameo Systems Modeler. Astah System Safety runs on Windows and macOS. FTA and FMEA are not included. A 40-day free trial is available.

About

Risks are inherent in asset-intensive, high-hazard facilities, and especially where the risk data set is vast with process safety risk spread across the organization. It’s difficult to standardize and assess all the sources of risk to support resource-intensive facilities. Sphera’s PHA-Pro offers a framework, configurable methodologies and risk assessment workflows to help organizations standardize and record risk assessment data and ensure proper controls are in place. Our PHA-Pro software is the most recognized and respected hazard identification and risk assessment tool for strengthening the risk assessment process. It helps identify, assess and control the impact of process-related risk. And Our expert facilitators have extensive experience performing risk assessments based on any methodology, including: HAZOP, What/If FMEA, FMECA PHA revalidation Workplace Job Safety Analysis (JSA) Layers of Protection Analysis (LOPA) and Safety Integrity Levels (SIL) SVA
