Why is cross-platform patching such a big deal?

Because Windows-only patching tools have left systematic gaps in Linux servers and macOS endpoints for years. Cyber-insurance assessors and CMMC C3PAOs increasingly ask about *all* operating systems on the network, not just Windows. A platform that treats Windows, macOS, and Linux as first-class closes audit findings the customer didn't know they had.

Does Lavawall® patch the Linux distribution itself or just applications?

Both. Lavawall® handles operating system updates and the 7,500+ application catalog across Debian-family and Red Hat-family Linux distributions, along with the equivalents on Windows and macOS.

Does the macOS agent require privacy & security permissions?

No. Lavawall® was designed so MSP clients in BYOD fleets can install the agent themselves or have it deployed via an existing MDM without granting privacy & security permissions.

Where is the patch catalog published?

At /publicappdetails.php on lavawall.com. The catalog lists every application Lavawall® patches, with links to release notes and CVE references where applicable.

Best cross-platform patch management for MSPs (Windows, macOS, Linux) (2026)

Patch management was a Windows-only discipline for two decades. Today it cannot be — your average client fleet has Intel and Apple Silicon Macs, Windows desktops and laptops, headless Linux servers, and a long tail of third-party applications that the operating-system vendor will never push.

Cyber-insurance assessors and CMMC 2.0 / NIST 800-171 auditors increasingly ask about *cross-platform* patch hygiene specifically. They have noticed that Linux file servers, RHEL-derived appliances, and macOS endpoints in BYOD fleets are where the unpatched vulnerabilities tend to live.

A useful cross-platform patch tool delivers parity: same console, same reporting, same SLA-tracking for Windows, macOS, and Linux — and a third-party application catalog deep enough to cover the long tail without a per-app surcharge.

What to look for

Single agent across all three platforms. Look for one agent on Windows, macOS, and Linux. Multi-agent stacks fragment your evidence, multiply your maintenance, and create silent gaps where one agent dies and the others do not notice.
Public application catalog. The patch catalog should be published openly so you can verify before adoption that the tool covers your specific applications. Vague "thousands of applications" claims are not enough.
Linux distribution coverage. Look for Debian-family (Debian, Ubuntu, Mint), Red Hat-family (RHEL, CentOS, AlmaLinux, Rocky, Fedora), and SUSE coverage at minimum. Coverage of Snap, Flatpak, and apt / dnf repositories matters for desktop Linux.
macOS coverage. Look for both Intel and Apple Silicon coverage, support for Mac App Store updates, MDM-coexistence (so the tool does not fight Jamf, Mosyle, Kandji, or Intune), and reasonable behaviour on BYOD devices that lack the privacy & security permissions.
Severity / CVSS-driven scheduling. Not every patch is equal. Look for severity-aware scheduling that defers low-risk patches and accelerates critical CVEs.
Reboot management. The patch tool needs to handle reboot deferral, user prompts, scheduled reboot windows, and reboot-pending detection so endpoints actually finish their patch cycles.
Audit-ready reporting. Reports should map to CMMC 2.0, NIST CSF, NIST 800-171, CIS Controls, PCI DSS, and HIPAA without manual re-mapping.

Options to evaluate

Lavawall®Cross-platform patching bundled with security and GRC

7,500+ applications publicly listed at /publicappdetails.php across Windows, macOS, and Linux from one agent. Combines OS patching, third-party application patching, configuration assessment, and reboot management. Maps automatically to CMMC 2.0, NIST CSF, CIS, SOC 2, ISO 27001, HIPAA, PCI DSS, PIPEDA, and 7 more frameworks. macOS works on BYOD without requiring privacy & security permissions or MDM enrolment.

Best when: MSPs that want one agent on Windows, macOS, and Linux with the patch catalog, configuration assessment, and audit-ready reporting in the same console.

NinjaOne / Datto RMM / ConnectWise Automate / N-ableRMM-bundled patching

Each major RMM ships its own patch module. Coverage is strong on Windows, varies on macOS, and is typically thinnest on Linux. Third-party application catalogs vary widely. Useful if patching is the only need; less useful when GRC evidence and breach detection are required.

Best when: MSPs whose patching needs are entirely Windows-centric and whose RMM patch module already covers their long-tail applications.

AutomoxCross-platform cloud-native patch tool

Cloud-native cross-platform patching with reasonable Linux and macOS support. Standalone — does not include GRC, breach detection, or helpdesk. Pricing is per-endpoint subscription.

Best when: IT teams (not MSPs) that want a focused patching tool and have GRC, breach detection, and ticketing handled elsewhere.

Action1Free-tier patch management

Free for the first 200 endpoints with paid expansion above that. Strong on Windows; macOS and Linux coverage is more limited; not multi-tenant in the MSP sense.

Best when: Small IT shops below 200 endpoints with primarily Windows-based fleets.

ManageEngine Patch Manager Plus / PDQ Deploy + InventoryOn-premises patching

Mature on-premises tools with deep Windows control. Limited cloud / multi-tenant story for MSPs serving many client networks.

Best when: Single-organisation IT teams that prefer on-premises tooling.

How Lavawall® fits

Lavawall® patches 7,500+ applications across Windows, macOS, and Linux from a single agent. The catalog is published openly so MSPs can verify coverage before adoption — there is no opaque "thousands of applications" handwave.

Linux coverage spans Debian-family (Debian, Ubuntu, Mint) and Red Hat-family (RHEL, CentOS, AlmaLinux, Rocky, Fedora) distributions. macOS coverage handles Intel and Apple Silicon and works on BYOD endpoints without requiring the privacy & security permissions that Mac users typically resist.

Because Lavawall® is also the GRC tool, the patching evidence becomes compliance evidence automatically — your CMMC 2.0, NIST CSF, CIS, SOC 2, ISO 27001, HIPAA, and PCI DSS controls reflect the actual patch state of every endpoint, continuously, without manual re-mapping.

Replacement prioritization is the other side of the same coin: when an endpoint cannot be patched (because its OS is end-of-life, the TPM is too old, or the RAM is too low to run a current patched build), Lavawall® scores it for replacement and surfaces it in the next QBR.
