Managed IT services with security as the default configuration
Managed IT and infrastructure services run by a security company: endpoint and server management, Microsoft 365 administration, patching, hardening, backup and disaster recovery, and a responsive helpdesk, with security engineering as the default posture.

01The problem
Many IT providers treat security as an add-on.
Unpatched servers, flat networks, shared admin passwords, backups that were never restore-tested. Many incidents begin as routine IT hygiene failures, not sophisticated attacks. Traditional managed service providers optimize for tickets closed, not attack surface reduced.
We run IT the way a security team would: least privilege by default, patched on a measured cadence, hardened against known tradecraft and monitored for the signals that matter.
- Hygiene stops most commodity attacks
- Patching, hardening and least privilege remove the openings commodity attacks depend on. It is the cheapest risk reduction available.
- One accountable team
- When IT and security are separate vendors, gaps live in the seam. A single team owns both the uptime and the attack surface.
- Recovery is a rehearsed skill
- Backups only count if restores are tested. DR only works if it has been exercised. We treat both as operational disciplines.
02Scope
What managed IT covers.
Managed IT Services
Day-to-day IT operations under SLA: monitoring, maintenance, user support and vendor coordination.
IT Infrastructure Consulting
Architecture and modernization advice for server, network and end-user computing estates.
Infrastructure Monitoring
Availability, capacity and health monitoring with alerting that reaches the right people before users do.
Server Management
Provisioning, patching, hardening and lifecycle management for Windows and Linux estates.
Network Management
Switching, routing, firewall and Wi-Fi administration with segmentation and change control.
Endpoint Management
Device provisioning, MDM, configuration baselines and compliance for laptops and mobile fleets.
Microsoft 365 Administration
Tenant management, licensing, mail flow, collaboration and security configuration, run by the same organization that does Microsoft 365 security hardening.
Active Directory & Identity Management
Directory operations, group policy, lifecycle automation and hygiene.
Patch Management
Risk-ranked patching across OS and third-party software with measured coverage reporting.
Endpoint & Infrastructure Hardening
CIS-aligned baselines applied and maintained across servers, endpoints and network devices.
Backup & Disaster Recovery
Immutable backup design, restore testing and DR planning with defined recovery objectives.
IT Helpdesk
Responsive user support with security-aware triage. Password resets done safely, phishing reports taken seriously.
Asset Management
Hardware and software inventory, lifecycle tracking and license compliance.
IT Security Architecture
Security-first design for IT changes: new offices, migrations, integrations and vendor onboarding.
03Approach
How a managed IT engagement runs.
Baseline
Asset inventory, configuration review and risk snapshot of the current estate.
Stabilize
Close the urgent gaps: patching backlog, backup integrity, admin access hygiene.
Standardize
Hardened baselines, documented processes and monitoring across the estate.
Operate
SLA-backed operations with monthly reporting on health, tickets and security posture.
Improve
Quarterly reviews driving modernization, cost optimization and risk reduction.

05Questions
Managed IT: questions we are asked
Security is our core discipline, not a menu item. Hardening, least privilege and monitored telemetry are the default configuration of everything we manage. The same organization runs security operations and can respond when something suspicious appears.
Yes. Common models include us handling infrastructure and security while your team owns applications and users, or providing overflow and after-hours coverage.
Yes. Modern endpoint management, identity-based access and secure remote connectivity are standard, not special projects.
Day-to-day operation of the systems a business runs on: user and device management, Microsoft 365 or Google Workspace administration, servers and networks, patching, backup and recovery testing, and a helpdesk for staff. Scope is set out in a service description, so it is clear which systems are covered, which hours apply and what stays with your own team.
Security settings are part of the baseline, not an extra. That includes multi-factor authentication and conditional access, Intune compliance policies so that only healthy devices reach company data, Defender for email and endpoint protection where licensed, and review of sharing, guest access and mailbox forwarding rules. Deeper work is covered under Microsoft security.
It begins with discovery: an inventory of users, devices, servers, licences, network equipment and existing documentation. Access is transferred and credentials are rotated, monitoring and management agents are deployed, and urgent gaps such as failed backups or missing patches are fixed first. The environment is then brought to the agreed baseline in planned steps.
Yes, and it removes a common gap. When one company patches the systems and another watches them, alerts and fixes pass between suppliers slowly. Combining managed IT with a managed SOC means the analysts who see an alert work with the engineers who can act on it, under one service model.
