Red Slice Group maintains this free security self-assessment tool to support planning, advance work, and general situational awareness through structured questions and real-time contextual inputs. The tool operates entirely on the client side; all data queries occur locally within the user’s browser, and no information is stored, recorded, tracked, or transmitted by or to Red Slice Group, LLC. This self-assessment provides a high-level overview of physical security practices and is intended as a practical resource to support security thinking and informed discussion. It is not a substitute for a professional audit, inspection, regulatory compliance review, formal risk or vulnerability assessment, professional education or training, operational judgment, site-specific verification, or independent fact-checking of locations, conditions, or capabilities. Results and recommendations are provided for informational purposes only and do not guarantee safety, security, or the prevention of incidents. Every facility faces unique risks and conditions. Red Slice Group, LLC assumes no responsibility or liability for actions taken or not taken based on the use of this assessment. This tool is intentionally under continuous improvement as conditions, risks, and best practices evolve. Feedback from practitioners and users is welcome and helps inform future updates.
