Patch Management Policy Template: A Sample Policy You Can Copy
Most patch management policies fail in one of two ways. Either they do not exist, and patching runs on habit and whoever remembers, or they exist as a twelve-page document nobody has opened since the last audit. A useful patch management policy sits in between. It is short enough to read, specific enough to be tested against, and written so that a new technician could follow it on day one.
This post gives you a sample patch management policy you can copy, followed by guidance on adapting it. If you want the operational reasoning behind the choices, read Patch Management Best Practices for MSPs alongside it.
How to Use This Template
Three notes before you copy anything.
Replace everything in brackets. Names, day counts, window times, and review dates are placeholders. The policy only works if the values are ones your team can actually meet.
The SLA day counts are common example values, not a standard. Frameworks and cyber insurance questionnaires generally ask that you define remediation timelines by severity and then prove you met them. They do not all agree on a number, and some name no number at all. Set timelines you can defend and hit consistently. A 14-day target you meet every month is stronger audit evidence than a 3-day target you miss.
MSPs should keep one master policy and a short per-client addendum. The master policy covers how you patch. The addendum covers what is different for that client: maintenance windows, excluded systems, named approvers, and any contractual timelines.
The Sample Patch Management Policy
Copy from here down to the end of section 13.
1. Purpose
This policy defines how [Organization] identifies, evaluates, tests, deploys, and verifies software updates on the systems it owns or manages. Its goals are to reduce exposure to known vulnerabilities, limit disruption caused by updates, and produce records that show patching was performed consistently.
2. Scope
This policy applies to:
- Workstations, laptops, and servers running Windows, macOS, or Linux
- Operating systems and third-party applications installed on those devices
- Firmware, BIOS/UEFI, and drivers where the vendor publishes security updates
- Network devices, hypervisors, and appliances managed by [Organization]
- Cloud-hosted and virtual systems where [Organization] is responsible for the operating system
Out of scope: [list systems patched by a vendor under contract, SaaS applications patched by the provider, and personally owned devices if applicable]. For each out-of-scope system, record who is responsible for patching it.
3. Roles and Responsibilities
- Policy owner: [Name or role]. Approves this policy, approves risk acceptances, and reviews it on the cadence in section 13.
- Patch manager: [Name or role]. Runs the patch cycle, approves or defers patches, and owns reporting.
- Technicians: Deploy patches, verify results, and document failures and rollbacks.
- System or application owners: Confirm that business applications work after patching and request exceptions when needed.
- Client contact (MSPs): [Name or role]. Approves maintenance windows and signs risk acceptances for their organization.
4. Asset and Software Inventory
[Organization] maintains a current inventory of all in-scope devices and the software installed on them, including version numbers. The inventory is updated automatically by [tool] and reviewed [monthly]. A device that is not in the inventory cannot be considered patched. Newly discovered devices are enrolled or documented as out of scope within [5] business days.
5. Patch Identification
Available updates are detected by automated scanning at least [daily]. The patch manager also monitors vendor security advisories and the CISA Known Exploited Vulnerabilities catalog for issues affecting software in the inventory.
6. Severity Classification and Remediation Timelines
Each patch is classified using the vendor severity rating and CVSS score, adjusted for exposure (internet-facing, sensitive data, business critical) and known exploitation.
| Severity | Definition | Example target to deploy |
|---|---|---|
| Emergency | Actively exploited, or critical on an internet-facing system | [48 to 72 hours] |
| Critical | Vendor critical or CVSS 9.0 and above | [7 days] |
| High | Vendor important or CVSS 7.0 to 8.9 | [14 days] |
| Medium | CVSS 4.0 to 6.9 | [30 days] |
| Low and non-security | CVSS below 4.0, feature and quality updates | [60 to 90 days, or next scheduled cycle] |
The clock starts when the vendor releases the patch. Timelines are measured to verified installation, not to approval.
7. Testing and Staged Rollout
Patches are deployed in rings. A patch advances to the next ring only after the soak period passes with no unresolved failures.
| Ring | Members | Example soak period |
|---|---|---|
| Ring 0 | [Organization] internal and IT devices | [24 to 48 hours] |
| Ring 1 | Pilot group: a small set of representative devices per site or client | [48 to 72 hours] |
| Ring 2 | General workstation fleet | [3 to 5 days] |
| Ring 3 | Servers and business-critical systems | Final ring |
Emergency patches may compress or skip soak periods under section 9. Ring membership is reviewed [quarterly].
8. Maintenance Windows
Patches that require a restart are installed only during approved maintenance windows:
- Workstations: [weekdays 8 PM to 6 AM, weekends any time]
- Servers: [Sunday 2 AM to 5 AM]
- Exceptions: [list 24/7 systems and their windows]
Users receive [24 hours] notice of a forced restart. Devices that miss a window are patched in the next available window. Devices offline for more than [14] days are flagged for follow-up.
9. Emergency Patching
When a vulnerability is actively exploited or the vendor issues an out-of-band fix, the patch manager may declare an emergency patch. Emergency patches may be deployed outside maintenance windows and may skip ring soak periods with approval from [policy owner]. The affected client or business owner is notified before deployment where practical. Where no patch exists, a documented mitigation (configuration change, service disablement, network isolation) is applied until one is available. Every emergency patch is recorded with the reason, approver, and outcome.
10. Exceptions and Risk Acceptance
If a patch cannot be applied within its timeline, the system owner submits an exception request containing: the system, the patch, the reason, compensating controls, and an expiry date no later than [90] days out. Exceptions are approved by [policy owner] and, for MSP clients, signed by the client contact. Exceptions are tracked in [register or ticket system] and reviewed [monthly]. An expired exception is either renewed with fresh approval or remediated.
11. Rollback
Before patching servers and business-critical systems, a current backup or snapshot is confirmed. If a patch causes a functional failure, the technician pauses further deployment of that patch, removes it or restores the system, and opens a ticket. The patch is marked deferred or rejected until the vendor issues a fix or a workaround is tested. Rolled-back patches are tracked as open exceptions under section 10.
12. Reporting and Audit Evidence
The patch manager produces a [monthly] report containing:
- Patch compliance percentage by device group or client
- Patches outstanding past their timeline, with reasons
- Failed installations and rollbacks
- Open exceptions and their expiry dates
- Emergency patches declared in the period
Records of patch approval, deployment, and verification, with timestamps, are retained for [12 months or longer if required by contract or regulation].
13. Review
This policy is reviewed [annually], and after any significant patch-related incident, tooling change, or change in regulatory or contractual requirements. Revisions are approved by the policy owner and recorded with a version number and date.
Adapting the Template
Set timelines from your capacity, then tighten
Look at your last three patch cycles. How long did critical patches really take to reach verified installation across the fleet? Set your first targets slightly tighter than that and improve from there. If a client contract, cyber insurance application, or regulator names a specific timeline, that number overrides the example values above for the systems it covers. Record where the number came from.
Size the rings to your fleet
A five-person office does not need four rings. Two will do: your own devices first, then everyone else a few days later. The principle is that no patch reaches every device at the same moment.
Write the client addendum
For each client, a single page covers it: maintenance windows by device role, systems excluded from automatic patching and why, the named client approver, any contractual timelines, and how restart notices are delivered.
Make the exception process easy to use
If requesting an exception is painful, people skip it, and you end up with unpatched systems nobody has formally accepted the risk for. A ticket template with five fields is enough. The expiry date is the part that matters most, because it forces the conversation to happen again.
Test the policy against reality
A quarter after adoption, pick five patches at random and trace each one: when it was released, approved, deployed, and verified, and on which devices. If you cannot produce that trail in a few minutes, fix the process or change the policy to match what you can sustain.
Common Mistakes
- Copying day counts without checking them. The fastest way to fail an audit is to publish a timeline you do not meet.
- Scoping only the operating system. Browsers, PDF readers, runtimes, and remote access tools need the same treatment. See automated and third-party patch management for how to cover them.
- No owner for exceptions. An exception with no expiry and no approver is just an unpatched system.
- Confusing patching with vulnerability management. They are linked but not identical. See patch management vs vulnerability management.
Where Breeze Fits
Disclosure: we build Breeze, an open source RMM, so treat this section as a vendor describing its own product.
A policy like this one is tool-neutral. If you use Breeze, several sections map to platform features. Patch management covers scanning for available updates, approving, rejecting, or deferring patches, deploying through patch jobs with per-device outcomes, and rollback. Approvals are scoped per organization, which suits the per-client addendum model. Update rings support staged deployment with ring ordering, deferrals, deadlines, and ring-scoped approvals, and policies can auto-approve patches by severity with optional deferral windows. Maintenance windows can be resolved through the policy hierarchy across organizations, sites, and groups. Patch posture can be summarized for operational review and customer reporting.
None of that writes the policy for you, and no tool makes an organization compliant with any framework on its own. The day counts, the exception approvals, and the judgment calls are still yours.
If you are evaluating tools, see the free RMM page and pricing.
