Key Points
- Patch caching stores software updates locally so that devices can download them from a local source to make patching less demanding on network bandwidth.
- Assess network topology and bandwidth constraints to determine where patch caching delivers the greatest efficiency.
- Select the appropriate caching technology:
- Delivery Optimization (DO) for Windows 10/11 environments on LAN or VPN.
- BranchCache for larger branch offices with moderate bandwidth and many devices.
- WSUS or third-party servers for enterprises needing strict compliance and centralized control.
- Design patch caching policies around subnets and groups to ensure updates are shared locally.

- Monitor effectiveness using tools like PowerShell to track cache hit rates, bandwidth savings, and deployment speed.
- Document caching in network design artifacts for audits, transparency, and long-term maintenance of patching practices.
Patch caching can help optimize bandwidth and accelerate network patching cycles. But instead of enabling it reactively when performance issues appear, as many MSPs and IT admins do, it’s good practice to integrate the process into the client network design itself during the building stage. This ensures each site has caching technologies and policies tailored to its needs.
This article will walk you through the steps for streamlining patch management by integrating caching into client network architectures. Keep reading to learn more.
Steps for incorporating patch caching into client network design
To successfully integrate patch caching into client network design, you must treat it as a foundational element of network architecture patching rather than an afterthought. Follow the steps below for a structured framework on how to do this.
📌 Prerequisites:
- Familiarity with caching technologies (Windows Delivery Optimization, BranchCache, or WSUS)
- Administrative rights to configure caching policies via GPO, Intune, or registry settings
- Inventory of client site topology (HQ, branch offices, remote workers)
- Defined bandwidth thresholds and patch compliance SLAs
- Access to monitoring and reporting tools for caching performance (Event Viewer, PowerShell, or Intune reports)
Step 1: Assess network topology and bandwidth constraints
First, you must evaluate the existing network topology and bandwidth landscape. This should help you understand how sites are connected and where bandwidth limitations exist. Consider the following tasks for a tailored solution:
Task 1: Identify high-bandwidth HQ sites vs. constrained branch offices
Larger headquarters usually have robust internet connections to handle repeated patch downloads. However, they also host a large number of endpoints, and if every device attempts to download patches directly from external servers at the same time, even a high-capacity connection can become saturated.
On the other hand, smaller branch offices may struggle with limited bandwidth and can benefit even more from local or peer-to-peer caching. It’s important to evaluate both network capacity and the number of endpoints at each site to determine where implementing patch caching will deliver the greatest performance and efficiency gains.
Task 2: Map subnets and VPN links that could affect peer-to-peer caching
Peer-to-peer caching technologies, such as Delivery Optimization, are subnet-aware, meaning they function optimally when devices share the same logical network. If endpoints connect over VPN, caching behavior may vary depending on individual configuration.
Task 3: Determine which locations will benefit most from local caching
Some sites may not need caching at all. Base your decision on bandwidth availability, number of endpoints, and patch compliance requirements.
Step 2: Select the appropriate caching technology
Next, select the caching technology that best fits the site’s environment. Consider the number of endpoints, network layout, compliance requirements, and administrative resources available. Here are some options:
| Caching technology | Best fit for | How it works |
| Delivery Optimization (DO) | Modern Windows 10 or 11 fleets on LAN or VPN | Peer-to-peer sharing of patch files between devices on the same subnet or VPN group |
| BranchCache | Larger branch offices with moderate bandwidth and many devices | Can be configured as Distributed (peers share files) or Hosted (one caching server per site) |
| WSUS or third-party caching servers | Enterprises with strict compliance and centralized management needs | Centralized servers download patches once, then distribute to all endpoints according to policy |
💡 Note: NinjaOne also supports patch caching as part of its patch management platform. MSPs can leverage this platform as an alternative to simplify bandwidth management and ensure consistent patch delivery. See the NinjaOne integration section for more information.
After selecting the right technology, it’s essential to document the method that applies to each client site. This ensures a consistent rollout for easier troubleshooting.
Step 3: Design patch caching policies around subnets and groups
Now, you must design policies to ensure updates are shared efficiently with the right devices. This should help prevent wasted bandwidth and improve cache hit rates. Here are some tasks to put this into practice:
Task 1: Use Delivery Optimization group IDs or Intune rings to segment devices by site
In Group Policy or registry, configure Delivery Optimization with a unique Group ID per subnet or site, so devices share updates only with local peers. In Intune, create update rings for each site or office location.
Task 2: Ensure peer groups are aligned with physical or logical networks
Map subnets for each office or branch, then assign caching groups that match those subnets (e.g., HQ, Branch A, Branch B) to prevent unnecessary cross-site traffic.
Task 3: Configure cache retention age and disk space limits
In Delivery Optimization or BranchCache settings, define how long cached content is stored (e.g., 7–30 days depending on patch cadence). To avoid performance issues on user devices, set a maximum disk usage percentage (e.g., 10–20% of free space).
Step 4: Incorporate caching into patch SLAs and compliance planning
Aside from optimizing bandwidth, caching should also directly support an organization’s compliance and service-level agreements (SLAs). Consider doing the following:
Task 1: Define how caching supports compliance timelines
Map caching policies to patch SLAs (e.g., “95% of devices patched within 7 days.”). You can then use cache hit ratios to demonstrate how local sharing accelerates deployment.
Task 2: Ensure caching does not delay distribution to critical systems
Configure caching to ensure high-priority devices (e.g., servers, executive endpoints) receive patches immediately from WSUS or the cloud. If needed, you can use Intune rings or GPO exceptions for critical systems to bypass peer-sharing.
Task 3: Document caching in patch management SOPs and compliance reports
Update SOPs (Standard Operating Procedures) to include caching in the patch workflow. This enables you to more easily incorporate cache performance metrics like hit ratios and bandwidth savings into compliance or audit reports for stakeholders.
Step 5: Validate and monitor effectiveness
It’s also crucial to have ongoing validation and monitoring steps to confirm your patch caching strategy is delivering the expected benefits. You want to measure effectiveness to prove value to stakeholders and adjust strategies where needed. To do this:
Task 1: Use PowerShell to track cache hit ratios and bandwidth savings
Delivery Optimization includes built-in PowerShell cmdlets to monitor performance. For example:
Get-DeliveryOptimizationPerfSnapThisMonth
Run the script on a sample of endpoints across different sites. It will give you some statistics for the current month, including:
- Data retrieved from peer devices
- Data downloaded from Microsoft servers
- The percentage of updates sourced from peers vs. external downloads
You can then compare cache hit rates between sites to identify where caching is working well and where it is underutilized.
Task 2: Monitor Intune or WSUS compliance dashboards
- In Intune, check the “Update Compliance” reports, which show deployment progress, failed updates, and the percentage of devices patched.
- In WSUS, review synchronization and reporting logs to confirm patches are distributed through local servers rather than external downloads.
- Use these dashboards to validate that caching isn’t slowing down SLA achievement (e.g., all devices patched within 7 days).
Task 3: Collect baseline vs. post-caching metrics to confirm value
To demonstrate ROI, performance must be measured before and after caching is implemented.
- Baseline: Record bandwidth usage during a typical patch cycle without caching, including WAN utilization, patch compliance time, and update success rates.
- Post-caching: Gather the same metrics after enabling caching. Look for reduced WAN traffic, improved patch deployment times, and stable or improved compliance.
You can present your findings in a side-by-side comparison for stakeholders, highlighting tangible savings and faster update cycles.
Step 6: Document caching in network design artifacts
Lastly, you must document everything to support internal IT operations while providing clients with transparency and measurable proof of value. Make sure to:
Task 1: Maintain a patch caching register per client
Create a standardized register (spreadsheet, database, or NinjaOne Docs) that tracks:
- Site: Each office, branch, or remote location
- Caching Technology Used: DO, BranchCache, WSUS, or third-party solution
- Bandwidth Baseline: Pre-caching bandwidth usage during patch cycles
- Cache Performance Results: Post-caching metrics, including cache hit ratios, bandwidth savings, and patch deployment times
Task 2: Include caching diagrams in network design documentation
Visual diagrams help clarify how caching operates across the client’s network. These diagrams should show:
- Which sites use which caching method
- How peer-to-peer or server-based caching flows within each subnet
- VPN links or WAN connections that affect caching distribution
Task 3: Use documentation to support procurement and QBRs
Well-maintained caching records and diagrams provide MSPs with powerful material for Quarterly Business Reviews (QBRs) and procurement discussions.

What is network patching?
Network patching is the process of distributing software updates to devices within an organization. It is done to fix security vulnerabilities, enhance performance, and maintain compliance.
Because patches must be deployed simultaneously across many endpoints, the process can create significant network traffic, especially in environments with multiple sites or remote users. This is where patch caching can add value.
Benefits of patch caching when implemented during the design stage
Planning for patch caching right from the start is a good strategy for MSPs to manage updates. Integrating it early on instead of later offers many benefits, such as the following:
- Reduced bandwidth strain and faster deployments
- Optimized support for branch offices and remote sites
- Flexible caching models for different environments
- Stronger compliance alignment
- Reduced WAN costs
Is patch caching safe?
Patch caching technologies, such as Windows Delivery Optimization and BranchCache rely on TLS encryption, Microsoft-managed certificates, and cryptographic hashes to ensure devices only receive update files that match the original publisher’s signature. To enhance network security, organizations should also enforce subnet-based sharing rules, implement role-based access controls, and store cached content on encrypted drives.
Automation touchpoint example
Automating cache performance monitoring can benefit MSPs and IT teams. This makes it a repeatable task that can be shown in audits and QBRs. Here’s a sample automated workflow:
- Use scheduled PowerShell scripts to collect key fields (e.g., bytes from peers/CDN, cache hit ratio, failed downloads, patch ring) weekly on representative endpoints.
- Automatically upload results to NinjaOne Docs (or a designated compliance repository) with a defined data retention to cover multiple patch cycles.
- Build lightweight dashboards and trends showing per-site summary (e.g., average cache hit ratio, total bandwidth saved, time-to-95% compliance).
- Set automatic ticket creation with severity level tags (e.g., warning, critical) for when cache hit ratios drop below defined thresholds.
- Document fixes and the subsequent week’s recovery metrics for audit traceability.
NinjaOne integration
NinjaOne offers a built-in patch caching solution designed to address bandwidth and latency challenges across distributed environments. By designating one or more local cache servers within a client’s network, the platform stores current patch content so that endpoints can retrieve updates directly from a nearby source instead of downloading them individually from the internet. This eliminates redundant traffic, accelerates patch deployment, and ensures reliable performance even in bandwidth-constrained or remote locations.
Integrated seamlessly into the NinjaOne agent, this feature supports Windows, third-party patching, and custom software updates, helping MSPs and IT teams maintain compliance, reduce WAN strain, and streamline patch operations from a single platform. Beyond its core caching functionality, NinjaOne also enhances patch caching management through several key integrations, as shown below:
| Integration point | How NinjaOne supports it |
