Why YUDU Sentinel?

Sentinel is a crisis communications platform to accelerate and improve your crisis response. Dynamic, digital tools allow you to send mass notification alerts, share documents, communicate via chat channels and attend instant conference calls.

Developed as a mobile-first solution, Sentinel is accessible anywhere, any time. Administrators have eyes-on access, with all data secured for post-incident review.

Sentinel is hosted on a single-tenant, secure cloud server to protect against cyber-attacks and server loss. The Sentinel crisis console is protected by two-factor authentication adding an extra layer of protection.

A white-label version of the Sentinel incident management app is available, allowing clients to add their own name and branding.

Sentinel is used for critical incident management & crisis response extensively in the financial, legal, entertainment and engineering sectors.

Mass Alerting

Sentinel crisis response software lets you:

  • Messages sent via, SMS, email, programmable voice, in-app or chat channels in less than 60 seconds.
  • Create template messages to ensure alerts are approved by senior leadership.
  • Custom alert sounds are used for urgent messages, so they're not confused with every-day notifications.
  • Two-way crisis communication checks everyone is safe.
  • Recipients can respond to yes/no questions ('Have you left the building?') and the answers are displayed in real-time on the Sentinel incident management dashboard.

Sentinel Document Centre
Secure Action Cards

Action Cards

  • In a crisis staff can forget training and protocols.
  • Bespoke scenario-based checklists help your team take the right decisions.
  • These cards are created in consultation with you, so that advice is specific to your organisation and premises.

Counter Terrorism Action Cards

  • We work with former senior police officer Chris Phillips to create counter terrorism advice.
  • Simply tap the scenario, such as 'Active shooter' or 'Suspicious package' to reveal the correct steps to take.

Mental Health Action Cards

  • Clinical psychologists at KRTS are trauma counselling experts.
  • They have developed an online course to help people recover from trauma.
  • The course, which contains video content, can be included in Sentinel's Document Centre.
  • It's there should your people experience a terror attack, workplace violence or bereavement.
  • The content is accessed anonymously through the app and can help friends, family and colleagues learn how to support those experiencing trauma.

Contacts Directory

  • A GDPR-compliant, ring-fenced directory for all your organisation’s contacts.

  • The directory syncs with your HR database.
  • Internal and external contacts can be grouped in whatever form works best for your organisation.
  • The Contacts Directory is quick to set up and easy to keep up to date.
  • Staff are prompted to verify their profile, check their contact details are correct, and have the option to make their profile private from others in the directory.

Sentinel Auditing and Compliance

Fully Audited & GDPR Compliant

When Sentinel is in use, every action and communication is saved in real time for post-incident analysis and learning.

The problem

  • Once an emergency is over there needs to be a post-crisis review.
  • An action plan must be drafted with plans and protocols updated.
  • During any incident it's important to log incoming information and to note when actions and decisions are taken and by whom.
  • In the heat of a crisis this information is sometimes never recorded or becomes misplaced.

The solution

  • Every detail of Sentinel usage is recorded, and a downloadable audit log available.
  • It is impossible to delete messages or other shared content.
  • Making it a superb resource for those tasked with implementing the post crisis report.

“The one thing that always goes awry during a crisis is communication with your staff and customers. Imagine having a system that not only allows you to tell them what needs to happen, but also allows them to reply. A system that puts all your business continuity plans at your fingertips. Well, I think you’ve found it.”

- Chris Phillips, GCGI, FSyl, Former Head of the National Counter Terrorism Security Office.
