How it works
Up and running in a day.
No lengthy onboarding, no consultant required. Three steps from sign-up to your first compliance report.
Connect your environment
Add your domain, email accounts, and existing tools in minutes. No agents to install, no firewall changes.
Scan and score
Sentinel assesses your security posture and compliance coverage, then gives you a single score and a clear picture of where you stand.
Comply and monitor
Work through prioritised remediation steps. Evidence is captured automatically, ready for your next audit.
Platform
Six modules. One platform.
Compliance, detection, response, intelligence, trust, and training. Everything working together, no reconciling alerts across vendors.
ShieldComply
Certification readiness and compliance operations in one workspace. No external consultant required.
ShieldDetect
Continuous monitoring of your credentials, domains, and exposure. Alerts before incidents, not after.
ShieldRespond
Incident response aligned with ICO and NCSC guidance.
ShieldIntel
Powered by AEGIS, our AI security agent. Alerts triaged and explained before they reach you.
ShieldTrust
External-facing security credibility for procurement, insurance, and customer assurance.
ShieldTrain
Short, practical security training your team will actually complete.
AEGIS
The security analyst that never logs off.
AEGIS is the AI agent at the centre of Sentinel. It watches your environment continuously, separates noise from real risk, and handles the routine work a security hire would, without the salary.
Reads every alert
Every signal from monitoring is assessed the moment it lands. Nothing sits in a queue waiting for morning.
Explains the verdict
Plain-English reasoning for every decision, mapped to the exact Cyber Essentials or GDPR control it affects.
Acts within limits you set
Routine issues are resolved autonomously. Anything unusual is escalated to a person, with the full context attached.
Alert · 02:37
Repeated sign-in failures on a dormant account
