Microsoft 365 is where your business lives — and where attackers look first. Cloud Shield 365 is Nostra's own product, protecting 160+ organisations today. It's available in three tiers: Cloud Shield Standard, Cloud Shield Plus and the full 10-layer Cloud Shield 365.
| # | Layer | What it does for you |
|---|---|---|
| 1 | CIS / Microsoft security framework | 20-point control set, MFA, conditional access, Secure Score maintained |
| 2 | Endpoint protection | Microsoft Defender for Endpoint with vulnerability management |
| 3 | Collaboration protection | Defender for Office 365: Safe Links, Safe Attachments, impersonation protection |
| 4 | Advanced email security | A second layer of AI-driven phishing and malware protection |
| 5 | Continuous M365 backup | Backup outside Microsoft — recover anything, any time |
| 6 | Intune device management | Corporate and BYOD devices secured and compliant |
| 7 | Ransomware detection | Detects encryption in real time and isolates the device automatically |
| 8 | Third-party patching | Closes the app vulnerabilities attackers target most |
| 9 | Immutable endpoint backup | Read-only backups of critical systems that ransomware can't touch |
| 10 | 24/7 SOC: EDR, ITDR, SIEM | Human threat hunters, identity threat detection, log retention |
Protecting 160+ organisations • 30,000+ endpoints supported across the group every day • Three tiers: Standard, Plus and Cloud Shield 365
Business Premium provides strong ingredients, but out of the box they're not configured, monitored or backed up. Cloud Shield 365 configures those tools to best practice, adds the layers Microsoft doesn't include — like continuous backup and a 24/7 SOC — and manages it all for you.
Microsoft provides resilience, not backup. If data is deleted or encrypted, retention windows run out. Cloud Shield 365 includes continuous backup outside Microsoft so anything can be recovered.
Encryption activity is detected in real time and the device is isolated from the network automatically, while our SOC investigates and begins recovery.
