A SEPERATE LINE OF COMMUNICATION

Your response cannot depend on the systems that have failed.

If a cyberattack or major IT outage affects email, collaboration tools or corporate networks, the channels used to coordinate a response may be affected too. Sentinel gives authorised teams a dedicated environment for communicating and responding.

Fully Independent

Your own single-tenant instance, with no shared platform to be compromised alongside other clients.

Reach Everyone

SMS and voice alerts, push notifications with acknowledgement tracking, and no app needed

Run the Response

Bring the right people together to make decisions with secure chat, video crisis rooms, documents, and a tamper-evident audit trail.

HOW SENTINEL SUPPORTS CNI RESILIENCE

Keep people connected. Keep the response moving.

A dedicated communications capability for the moments when normal systems cannot be relied upon.

Independent by design

Sentinel is hosted separately from primary corporate IT, with a dedicated single-tenant instance for each client. This separation helps preserve a communications route during disruption.

Coordinate at speed

Use secure messaging, targeted notifications and video conferencing to bring incident teams, operational leaders and decision-makers together.

Evidence as you respond

Auditable records of relevant communications and activity help teams review decisions, reconstruct events and support internal governance processes.

Preparedness you can test

Rehearse how teams communicate during a loss of primary IT, with dedicated incident spaces and access to critical documents, including offline viewing on supported mobile devices.
