Your Out-of-Band Communications Platform for Crisis-Ready Resilience

If Microsoft Teams or Slack are compromised by a cyberattack or major outage, Sentinel offers immediate continuity - keeping teams connected and your response on track.

Sentinel operates independently, creating a trusted space where critical messaging, plans, and collaboration bypass compromised systems—enabling your response teams to act quickly and decisively when it matters most. Regain the upper hand and stay one step ahead of hackers.

At Sentinel, security is not an add-on or afterthought - it’s embedded into the architecture, development process, and functionality of the platform from the outset

Our tools are purpose-built for crisis collaboration, allowing rapid escalation, secure file sharing, and real-time team coordination - helping you respond better and faster.

With full audit trails, secure data handling, and controlled access to sensitive information, Sentinel helps demonstrate compliance during audits and investigations.

Sentinel protects against insider threats, acting as a safe haven for privileged discussions- minimising exposure to compromised platforms or unauthorised access.
