Break-Fix vs Managed IT: A Fundamental Difference

Break-fix IT is reactive: something stops working, you call someone, they fix it. You pay per incident. The provider has no financial incentive to prevent problems โ€” more problems means more revenue.

Managed IT services are proactive: your IT provider monitors, maintains, and secures your environment continuously. Problems are detected and resolved before they affect operations. You pay a predictable monthly fee regardless of how many incidents occur โ€” so the provider has a direct incentive to prevent them.

The average cost of an IT incident for a small business is $10,000โ€“$50,000 when you include downtime, recovery, and staff disruption. Managed IT services typically cost a fraction of one incident per year.

Core Managed Service Components

Remote Monitoring and Management (RMM)

โœ“Continuous monitoring of all enrolled devices โ€” CPU, disk, memory, software inventory
โœ“Automated alerting on hardware failures, low disk space, service crashes
โœ“Remote access for support โ€” no need for on-site visits for most issues

04

Security as Part of Managed IT

The most important shift in managed IT in 2024โ€“2026 is the integration of security into the standard managed service. Monitoring endpoints for performance is no longer enough โ€” you also need to monitor for threats.

Security monitoring included in De4sec Managed IT

โœ“Microsoft Defender for Endpoint managed monitoring โ€” alerts triaged and investigated
โœ“Microsoft 365 security monitoring โ€” sign-in anomalies, unusual mailbox rules, admin changes
โœ“Patch compliance monitoring โ€” alert on devices that fall behind patch schedule
โœ“Failed login monitoring โ€” alert on brute force or credential spray attempts
โœ“Backup job monitoring โ€” alert on failed backup jobs, confirm restore test completion

Incident response coverage

When De4sec Managed IT detects a security incident, we don't just alert โ€” we respond. Containment, investigation, and remediation is included in the managed service, not billed separately as a one-off incident.
