# Best Critical Event Management (CEM) Platforms Software - Page 2 *By [Emma Stein](https://research.g2.com/insights/author/emma-stein)* Critical event management (CEM) platforms enable businesses and government agencies to proactively prepare for, respond to, and recover from incidents that threaten people and assets. These solutions centralize business continuity, natural disaster response, crisis and emergency management, IT risk management, and mass alerting and notification functions in one system. They integrate with key workforce and communications systems to bolster incident response. With a CEM platform, businesses and government teams can create emergency response plans, establish task assignments, plan for "what if?" scenarios, and assess threats in real time to promote crisis prevention. By connecting with GIS tools and communication channels, users can track the locations of all threatened people and provide updates, receive geo-tagged media to monitor incidents on the field and communicate with public and private emergency response officials. After an event has been resolved, CEM platforms enable users to audit data and determine the efficiency of their response, allowing them to alter their response plan for future critical events. CEM platforms go far beyond the capabilities of [emergency notification software](https://www.g2.com/categories/emergency-notification), allowing crisis management teams to monitor threats in real time, automate incident initiation responses, promote situational awareness, and improve collaboration to resolve events quicker. While public safety and healthcare officials may interface with CEM platforms for external responses, emergency dispatch teams will often prefer [emergency medical services software](https://www.g2.com/categories/emergency-medical-services) for the tailored features that support their unique workflow. To qualify for inclusion in the Critical Event Management (CEM) Platforms category, a product must: - Create compliant incident plans for a variety of scenarios with task assignments and automated workflows - Monitor relevant threats in real time and initiate incident response actions when pre-set thresholds are met - Send secure alerts and notifications to personnel, partner organizations, and public officials, and support collaboration with emergency responders - Leverage geolocation data to monitor personnel and assets before, during, and after incident response - Provide post-incident reporting and data analysis for auditing and event response improvement - Integrate with existing systems to promote alerting, communications, and collaboration ## G2 Grid® for Critical Event Management (CEM) Platforms Software ![G2 Grid® for Critical Event Management (CEM) Platforms Software plotting products by satisfaction and market presence](https://www.g2.com/categories/critical-event-management-cem-platforms/grids.png?focus%5B%5D=339&focus%5B%5D=22291&focus%5B%5D=5976&focus%5B%5D=22300&focus%5B%5D=1372144&focus%5B%5D=88178&focus%5B%5D=51457&focus%5B%5D=55717) Highlighted products: Everbridge 360 (Critical Event Management), AlertMedia, Dataminr, Regroup Mass Notification, Smart CAD, DisasterLAN, D4H, and Crises Control.

[SIRV](https://www.g2.com/products/sirv-systems-limited-sirv/reviews) SIRV is operational AI for safety, security and resilience teams. It is designed to help organisations with real operational work, not just generic AI tasks. Many teams do not need another AI tool. They need practical help retrieving the right procedure, evaluating important documents, triaging incoming information, building a clearer operational picture, and retaining useful lessons over time. SIRV is built around those kinds of workflows. At the centre of SIRV is an operational layer. This helps apply AI in a more controlled and useful way for higher-consequence environments. Rather than relying on prompting alone, SIRV is designed to support clearer limits around approved evidence, defined workflows, traceability, operational memory and human review where needed. This means teams can use AI in a way that is more practical for day-to-day operational work. Depending on the workflow, SIRV can help users: retrieve the right approved procedure or guidance more quickly check whether internal or third-party documents meet expected standards and are workable in practice triage incoming reports, messages or updates and focus attention on what matters most bring together relevant information to support a clearer operational picture keep a clearer record of actions, outputs and decisions retain useful operational knowledge, lessons learned and repeated patterns over time SIRV is particularly relevant where teams need more than a helpful answer. In many safety, security and resilience settings, outputs need to be reviewable, grounded in the right source material and shaped around how the organisation actually works. That is why SIRV focuses on controlled operational support rather than generic open-ended AI use. Typical use cases include: Procedure access under pressure Help staff find the right approved material quickly and reduce time lost searching across documents. Document evaluation Check whether policies, plans, RAMS, risk assessments or third-party documents include the right content, meet expected standards and are workable in practice. Triage Help teams sort incoming information, identify patterns and prioritise what matters first. Operational picture building Bring together relevant information from documents, reports or other inputs to support a clearer view of what is happening. Lessons learned and operational memory Retain and reuse useful knowledge so teams do not have to start again each time a similar issue arises. SIRV can support teams working in sectors such as corporate security, transport, critical infrastructure, life sciences, major venues, real estate, operational resilience and other environments where the cost of getting it wrong is high. The aim is not to remove human judgement. The aim is to support teams with faster access to the right information, more consistent handling of routine operational work, and clearer records that can be reviewed when needed. SIRV also sits within a broader operational platform context. Depending on the environment and workflow, it can support better reporting, visibility, document handling and connected operational processes. The focus remains practical deployment around real work, clear scope and outcomes that can be assessed in a sensible and reviewable way. If your team is exploring AI for safety, security or resilience, SIRV is designed for situations where trust, clarity and practical usefulness matter more than novelty. **Who Is the Company Behind SIRV?** - **Seller:** [SIRV Systems](https://www.g2.com/sellers/sirv-systems) - **Year Founded:** 2010 - **HQ Location:** London, GB - **Twitter:** @SIRV77173435 (1 Twitter followers) - **LinkedIn® Page:** https://www.linkedin.com/company/sirv (3 employees on LinkedIn®) ### 13.
