Questions about Sentinel?

Sentinel is designed for security professionals, event organisers, consultants and teams responsible for assessing vehicle access, crowded places and mitigation strategies.

No. Sentinel is focused on early-stage HVM assessment, option comparison and stakeholder communication. CAD and BIM tools remain appropriate for detailed construction and engineering documentation.

A typical workflow starts by mapping the real site and its access points. Teams then test hostile vehicle approaches, review potential speeds and trajectories, and compare mitigation layouts using the same site reference.

Scenarios can consider vehicle characteristics, approach paths, entry angles, trajectories and potential speeds against the real geometry of the location.

No. Sentinel supports professional planning and analysis, but its simulations are not themselves a certification. They help teams review scenarios and mitigation options using recognised HVM references as part of the wider design process.

Vehicle Dynamics Assessment (VDA) examines possible vehicle approaches, trajectories, speeds and potential impact energy in the context of the site. It helps teams compare vehicle scenarios and consider suitable mitigation layouts; it is not a certification of barrier performance.

Sentinel supports the planning of perimeter boundaries, access points and the positioning of fencing and gates alongside other protective measures. A fence should only be described as vehicle-impact protection where its tested performance supports that claim.

Vehicle Incursion Defence Systems are physical measures designed to help prevent unauthorised vehicle access, such as vehicle security barriers, bollards and appropriately specified gates. Sentinel helps teams plan their positions and compare alternative layouts in relation to vehicle approach routes, site boundaries and operational access requirements.

Sentinel is a planning and assessment tool: it does not physically stop vehicles, establish the impact rating of equipment or certify an installed protective system. Performance claims must be supported by the relevant product testing and engineering assessment.

Sentinel workflows can use site plans, imagery and GIS mapping context. Support for particular import formats, including KML and GeoJSON, and for specific export formats should be confirmed with the Sentinel team for your project.

Yes. The workflow can support planning for temporary event environments as well as permanent public, private or critical sites, depending on the access requirements and operational constraints of the location.

Sentinel can help prepare visual material showing barrier positions, vehicle trajectories and mitigation proposals for review and discussion. Ask the team which file export formats and sharing options are available.

Yes. One of Sentinel's strengths is turning technical HVM planning into visual material that is easier for authorities, clients, operational teams and other stakeholders to understand and discuss.

Site maps, access routes and protection layouts may contain sensitive project information. Ask the Sentinel team about the access controls, data handling arrangements and contractual confidentiality measures applicable to your deployment.

Data security is particularly important for site plans, access routes and protection layouts. Encryption can protect data in transit or in storage, but encryption alone does not establish that a system uses a zero-knowledge model. Please contact the Sentinel team to confirm the encryption methods, key management, access controls and data protection arrangements applicable to your deployment.

Zero-Knowledge Encryption is an encryption architecture in which only the user or authorised parties hold the means to decrypt protected content. The service provider cannot read that content because it does not possess the required decryption keys. This is different from simply encrypting stored data or avoiding password storage.

Whether Sentinel provides this architecture, and whether it covers site maps, imported files, scenarios, reports or other project information, must be confirmed with the Sentinel team. Ask about key ownership, recovery procedures, sharing permissions and any data or metadata excluded from protection.

Access permissions and confidentiality requirements should be assessed for your specific project and deployment. Contact the Sentinel team for the current information on authorised access, data storage and available security controls.
