Dev, then staging, then production in batches, with checks between each batch.
Rollback ready
Snapshots before patching and a 30-minute rollback window if anything breaks.
Clear communication
72 hours notice for routine patches, 24 hours for critical ones, and a summary report after.
Compliance tracking
Monthly reports on patches applied, pending updates, compliance status and vulnerability scans.
The quiet work that prevents outages.
- Health monitoring. Early detection of issues before they reach your users.
- Capacity planning. Resource tracking and growth planning.
- Documentation. Complete records of configurations and changes.
- Compliance monitoring. Ongoing checks against security and regulatory requirements.
- Vendor management. We coordinate with OS vendors for support and licensing.

Questions we hear often
What is OS management?
Maintaining, updating and securing your server operating systems: patching, hardening, monitoring, user management, backup configuration and troubleshooting.
Why does it matter?
Unpatched servers get breached (WannaCry spread through unpatched Windows). Monitoring prevents outages from full disks or exhausted memory, and tuning keeps apps fast.
Do you automate OS updates?
Yes. We use Ansible, Puppet and WSUS for routine updates. Kernel updates and major upgrades need your approval and a maintenance window.
How do you secure the OS?
Firewall hardening, vulnerability scanning (OpenVAS, Nessus), CIS and STIG benchmarks, SSH keys only, fail2ban, SELinux or AppArmor, and regular audits.
