Automated patch management for operating systems and third-party applications

Updated on

Patch management identifies, tests, approves and installs operating system and application updates within agreed policies and maintenance windows. Loonar designs and implements automation for local and remote devices, trains your teams and sustains the process with staged testing, failure handling and evidence that shows which devices meet your update policy.

In short

  • Prioritize updates by risk and criticality.
  • Test before broad deployment.
  • Verify installation with evidence.

How do you know you need patch management?

  • Remote devices fall behind

    Devices outside the corporate network miss updates when patching depends on an office connection. Teams lose visibility into failures and pending restarts, while known vulnerabilities remain on the laptops employees use to access business information and services.

  • Manual work consumes capacity

    Finding updates, running installations and checking results takes time away from planned work. Without clear policies and ownership, urgent requests drive the schedule and technicians follow different procedures, making operational handovers and audit preparation harder than they need to be.

  • Third-party applications get missed

    Browsers, PDF readers and archive utilities also need security fixes. When patching covers only the operating system, third-party applications accumulate vulnerable versions without appearing in the remediation backlog or receiving an accountable owner and a clear treatment deadline.

  • Updates disrupt critical services

    An untested update can break an essential application. Without rollout rings, stop criteria and a validated recovery plan, support teams have to improvise during an incident and take longer to restore the business services that depend on affected devices.

How does it work?

  • Device-based policies

    Set operating system and third-party application policies according to compatibility and available catalog coverage. Group devices by business criticality, usage and ownership rather than applying one rule everywhere.

  • Rollout rings and windows

    Organize pilot and broader deployment groups within agreed maintenance windows. Progression, pause and restart criteria reflect test results and the availability requirements of the services each device supports.

  • Risk-based approval

    Use severity, known exploitation and asset context to guide automatic or manual approvals. Give exceptions an owner, rationale and review date rather than allowing indefinite delays without accountability.

  • Problem update alerts

    Review available advisories about problematic updates before deployment. Compatibility signals inform temporary blocks, additional testing and owner communication, without assuming that every defect can be detected in advance.

  • Remote device delivery

    Deliver updates over internet connections without requiring VPN in supported scenarios. Track disconnected devices, retries and restarts so completed installations are clearly distinguished from tasks that were merely scheduled.

  • Audit-ready reporting

    Bring together versions, installation outcomes, exceptions and outstanding actions by device group. Evidence supports internal policy assessments and shows how teams investigate and resolve installation failures across the managed estate.

How does Loonar deliver?

  1. Environment assessment

    Loonar inventories devices, operating systems and applications, checking support requirements, connectivity and existing tools. The assessment identifies coverage gaps and assets needing a tailored approach before automated rollout begins.

  2. Policy design

    Agree groups, priorities, windows and ownership with business stakeholders. Define approval rules, restart behavior, exceptions and recovery criteria while respecting service availability needs, software support conditions and operational dependencies.

  3. Implementation and integrations

    Configure deployment, pilot rings and reporting. Connect failures and requests to support workflows, validating connectivity, permissions and installation outcomes before expanding the rollout to additional groups of managed devices.

  4. Operational training

    Train owners to approve updates, interpret failures and stop deployment when required. Practical exercises cover communication, exception records and recovery procedures, giving support teams guidance they can use during disruption.

  5. Operation and continuous improvement

    Monitor installations, outstanding updates and changes to application coverage. Refine policies and maintenance windows using observed results, review exceptions and retain evidence that supports a repeatable security maintenance process.

Where do we apply it?

  • Financial services

    Customer-facing and administrative devices need updates without disrupting critical business periods. Representative pilot rings and agreed windows support controlled rollout, with approvals for sensitive applications. Management receives installation evidence and documented exceptions, while support teams investigate failures before deployment expands to additional devices.

  • Retail and e-commerce

    Stores and administrative teams operate on different schedules. Grouping devices by role and availability avoids indiscriminate restarts during sales and customer service. Reports identify outstanding updates and failed installations so local owners can coordinate remediation without relying on disconnected manual checks across locations.

  • Healthcare

    Clinical and administrative workstations need policies compatible with the applications they run. Validate support requirements and separate equipment that requires specific manufacturer authorization. Testing and agreed windows guide deployment, while documented exceptions make risks visible without assuming every device can follow the same update procedure.

Frequently asked questions

What is patch management?

Patch management is the process of identifying, testing, approving, deploying and verifying updates for operating systems and applications. It includes inventory, priority rules, maintenance windows and failure handling, not just running an installer. Loonar designs policies, implements automation, trains the team and sustains the workflow. The goal is controlled exposure reduction, supported by evidence of what actually changed on managed devices.

How often should patches be applied?

Frequency depends on risk, asset criticality and availability requirements. Fixes for actively exploited vulnerabilities may need an emergency workflow, while other updates follow planned windows. Set deadlines by category, test compatibility and record exceptions. No single calendar suits every environment. What matters is a defensible priority order, accountable decisions and confirmation that approved fixes were successfully installed on the intended devices.

How do we update remote workers' devices?

Cloud-based management can deliver updates over the internet without VPN, provided devices are supported and can reach the required services. Policies control timing, restarts and retries. Devices that are offline or powered down still need follow-up. Reporting should separate devices with no recent contact from failed installations and successful updates, rather than presenting a scheduled task as proof that exposure has been addressed.

How can we prevent a patch from breaking systems?

Use representative pilot groups, test critical applications and define clear stop criteria. Monitor results before progressing to wider deployment, and agree maintenance windows with business owners. Recovery depends on the update and operating system: uninstalling a patch is not always possible. Validate restoration procedures, continuity options and responsibilities before authorizing higher-impact changes instead of treating rollback as a universal safeguard.

What is an alternative to WSUS?

Cloud patch management is a WSUS alternative that can apply policies to operating systems and third-party applications, subject to catalog coverage and compatibility. Evaluate restart controls, remote operation, reporting and recovery alongside application support. Start migration with a pilot and remove conflicting policies before expansion. Changing the tool alone does not guarantee compliance, complete coverage or a deployment process without failures.
