Core Services

We become your IT department — monitoring your environment 24/7, keeping systems patched and secure, and resolving issues before they slow your team down. CrestOne plans give you a complete IT solution at a predictable monthly cost.

• 24/7 RMM monitoring and alerting across all endpoints and servers
• Unlimited help desk support — real people, no ticket queues
• Automated patch management within defined maintenance windows
• Device provisioning, asset inventory, and lifecycle management
• Monthly business reviews with plain-language health reporting

Enterprise-grade security without an enterprise security team. EDR/XDR, SIEM, vulnerability management, and phishing simulations — layered on your environment and watched 24/7. Plus compliance support for HIPAA, PCI DSS, and CMMC.

• EDR/XDR endpoint detection and response across all devices
• SIEM log aggregation with 24/7 threat monitoring and alerting
• Vulnerability assessments with prioritised remediation
• Security awareness training and simulated phishing campaigns
• Incident response planning and tabletop exercises

Cloud done right — strategic migrations, Microsoft 365 and Azure management, identity governance, and ongoing optimisation. We treat cloud as a tool, not a destination, and move workloads when it actually reduces cost or improves security.

• Microsoft 365 and Azure migration, deployment, and ongoing management
• Azure AD / Entra ID, MFA, and conditional access policies
• SharePoint, Teams, and OneDrive governance and configuration
• Device compliance and Intune MDM/MAM management
• Cloud cost optimisation and license right-sizing
