MBITS provides fully managed Proxmox sustainment services designed to keep production environments stable, secure and performing as expected.
Deploying Proxmox is only the first step. Long-term stability, security and performance require continuous oversight and proactive management.
We deliver disciplined, end‑to‑end Proxmox management that ensures your virtual infrastructure remains secure, optimised and resilient long after deployment.
Many organisations invest in a well-executed migration only to find that ongoing management becomes an afterthought. Patches are deferred. Backups go unverified. Capacity issues surface without warning. Performance degrades gradually until it becomes a problem that cannot be ignored.
Proxmox is a capable platform. Without structured, proactive management, no platform maintains itself.
Sustainment is proactive management. It means preventing issues before they occur, ensuring the platform continues to support operational needs, and maintaining the governance and accountability that production-critical environments require.
Our sustainment services are designed for environments where uptime, reliability and accountability are not optional.
Proactive monitoring and alerting. We provide continuous monitoring across the Proxmox environment, including cluster health and node status, storage utilisation and performance, hardware and service health, and early detection of failures and bottlenecks.
Patch and update management. We manage updates in a controlled, low-risk manner, including Proxmox VE updates and security patches, kernel and firmware coordination, and change planning to minimise disruption.
Backup and recovery management. We ensure backups are reliable and recoverable through backup strategy design and validation, monitoring of backup success and failures, and restore testing and disaster recovery readiness.
Performance optimisation. We continuously assess and optimise platform performance through resource utilisation analysis, VM and storage tuning, and capacity planning and scaling advice.
High availability and resilience. We design and manage HA environments that support continuity, including HA configuration and monitoring, failover testing and validation, and cluster optimisation for reliability.
Deep Proxmox expertise is not common. Understanding how the platform behaves under real production conditions, at scale, across complex workloads, takes time and experience to develop.
MBITS brings hands-on Proxmox capability combined with a structured, governance-focused delivery approach. Our services are vendor-neutral, best-practice driven and designed for predictable cost and accountability.
Whether you have recently migrated from VMware or have been running Proxmox for years, our sustainment services ensure the platform remains secure, performant and resilient over time.

Each agent compares the current patch list against what is actually installed on its device. Any gap between what has been released and what is deployed is immediately surfaced. Critically, Introspectus pays particular attention to the timing of patch deployment not just whether a patch is present, but when it was applied.
This temporal dimension is central to Essential Eight compliance, where the difference between a patch applied on day two versus day thirty can mean the difference between maturity levels, and between an environment that was protected and one that was exposed.
This combination of daily patch intelligence, severity-based filtering, agent-level validation, and deployment timing analysis gives organisations a real-time, evidence-based view of their operating system patch posture mapped directly to the ISM controls applicable to the Essential Eight patch operating systems strategy.
The visibility gap here is particularly consequential. A patch may be approved and scheduled, yet never successfully applied due to a failed deployment, a device that was offline during the maintenance window, a reboot that was deferred, or a system that exists outside managed channels entirely.
Organisations that rely solely on deployment tooling to confirm patch status are measuring intent, not reality. The ACSC is explicit on this point: organisations need to confirm patches have been applied successfully, not merely that they were dispatched.
Within the Essential Eight framework, patching operating systems is a core and non-negotiable control. The ACSC sets clear expectations: patches for internet-facing infrastructure must be applied within 48 hours when identified as critical or where working exploits exist, and within two weeks for standard releases.
Patches for workstations, servers, and network devices must be applied within one month, with tighter timeframes applying in high-threat environments. Critically, the ACSC also mandates that vulnerability scanning occurs at least daily for internet-facing systems and at least fortnightly for workstations and non-internet-facing infrastructure not to replace patching, but to confirm it has actually occurred.
From this inventory, Introspectus performs targeted web intelligence gathering. For each application identified, the platform locates the top five authoritative sources of patch and release information vendor security advisories, release notes, and vulnerability databases and retrieves that content into a central repository.
Aletheia, Introspectus’s AI analysis agent, then reads and analyses this content to extract the intelligence that matters for application patching: the latest available version, whether a release addresses a security vulnerability, the severity of that vulnerability, and all information relevant to the Essential Eight application patching requirements. This structured intelligence is mapped directly to the applicable ISM controls, producing defensible, audit-ready evidence of an organisation’s application patch compliance posture.
A critical and frequently overlooked problem is the visibility gap. Organisations may believe their applications are current when, in reality, patches have silently failed, devices have missed deployment windows, or software has been installed outside of managed channels entirely.
Without continuous inspection at the endpoint level, these gaps go undetected until an audit or, worse, a breach.
Within the Essential Eight standard, patching applications is a dedicated and non-negotiable control. The ACSC specifies clear timeframes: critical vulnerabilities in internet-facing services must be addressed within 48 hours, commonly used applications such as office productivity suites, web browsers, email clients and PDF software must be patched within two weeks of release, and all other applications within one month.
For organisations in high-threat environments, the bar is higher still. Meeting these requirements consistently across hundreds of distinct applications deployed across thousands of endpoints is not achievable through manual effort alone.
