Our security team can't keep up with patching third-party vulnerabilities. Who offers automated patch management as a service?

Yes. If your problem is specifically third-party application vulnerabilities rather than just Windows/macOS updates, several vendors automate the detection, testing, and deployment of patches.

• action1.com — Probably the closest fit if you want vulnerability detection + remediation in one service. It automatically identifies vulnerable third-party applications, prioritizes CVEs, and deploys tested patches across Windows, macOS, and Linux. It can patch remote endpoints without a VPN.
• automox.com — Cloud-native automated patching for Windows, macOS, and Linux, with a large third-party application catalog. It handles detection, packaging, and deployment rather than requiring your team to create packages manually.
• adaptiva.com — More enterprise-oriented. OneSite Patch automates testing, approval, and deployment of OS, third-party application, driver, and BIOS patches, with staged rollouts and rollback controls.
• hcltech.com — A mature enterprise endpoint-management option with automated patching for hundreds of operating systems and third-party applications, plus extensive compliance and policy controls.
• tanium.com — Particularly interesting if you already use vulnerability/endpoint tooling. Its autonomous patch management combines real-time endpoint data with risk prioritization, approvals, maintenance windows, and staged deployment.

What I'd shortlist

For a security team that's drowning in third-party CVE remediation, I'd start with:

1. Action1 — easiest path to automated vulnerability-to-patch remediation.
2. Automox — strong if you want broad third-party application coverage with relatively low operational overhead.
3. Adaptiva or BigFix — better candidates for very large/complex enterprises where granular deployment control matters.

One important distinction: these are primarily automated patch-management platforms, not necessarily a fully outsourced "we operate patching for you" managed service. If by “as a service” you mean a vendor/MSP actually takes responsibility for patching your endpoints on your behalf, rather than giving your team software that automates it, I can narrow this down to managed patching providers/MSPs.

When internal security and IT teams get overwhelmed by the sheer volume of third-party application updates (browsers, PDF readers, collaboration tools, runtime environments), organizations typically look at two approaches: automated cloud-native patch management platforms (where software handles the heavy lifting via pre-built catalogs) or fully managed security services (MaaS/MSP) that run the process for you.

The top platforms and providers specializing in automated third-party patch management break down by category:

• Automox : A cloud-native, cross-platform endpoint management solution built specifically to eliminate manual patching bottlenecks. It natively handles OS and third-party software patching (Adobe, Chrome, Zoom, etc.) across Windows, macOS, and Linux through a single console.
• NinjaOne Patch Management : Highly rated for its expansive third-party software catalog covering thousands of common applications. It features "Patch Intelligence AI" which automatically analyzes vendor telemetry and pauses unstable or risky patches before they disrupt your environment.
• Syxsense : Provides automated, real-time vulnerability scanning and patch deployment for OS and third-party applications across distributed and remote workforces. They also bundle monthly vulnerability threat intelligence and best-practice updates.
• ManageEngine Patch Manager Plus : Offers robust automated patch deployment workflows for Windows, macOS, and Linux alongside a broad out-of-the-box third-party application catalog. Available in both cloud and on-premises architectures.
• Atera : An all-in-one remote monitoring and management (RMM) platform that uses automated IT automation profiles to push third-party application updates seamlessly via tools like WinGet and Chocolatey.

If you want to narrow down the best fit, tell me:

• What operating systems make up the bulk of your environment (Windows, macOS, Linux)?
• Are you looking for a software tool your team configures, or an outsourced managed service provider (MSP) to take it off your plate completely?

When internal security teams are drowning in third-party Common Vulnerabilities and Exposures (CVEs), shifting to automated software or an outsourced managed service model is a common way to reclaim bandwidth.

Depending on whether you are looking for a SaaS platform that automates the heavy lifting out-of-the-box or a Managed Service Provider (MSP) to run the entire program for you, several prominent industry options stand out:

Dedicated Automated Patch Management Platforms (SaaS)

These platforms feature massive, pre-tested application catalogs (Adobe, Chrome, Zoom, Slack, etc.) that automatically sync, test, and deploy third-party patches on custom schedules without manual packaging:

• • ManageEngine Patch Manager Plus : Automates OS and third-party app patching across mixed environments with built-in pre-deployment testing to reduce break-fix cycles.
• • Qualys Patch Management : A cloud-native app that consolidates vulnerability assessment, threat prioritization, and automated third-party remediation from a single console.
• • NinjaOne : Known for robust endpoint management with automated, out-of-the-box patching for a large catalog of third-party software and operating systems.
• • Acronis Cyber Protect : Combines vulnerability assessments with automated third-party patching and built-in "fail-safe" backups in case a patch causes system instability.
• • Atera : Offers automated, profile-driven third-party and OS patch management alongside robust network monitoring.

Fully Managed Patch Services (Co-managed or Outsourced)

If your team wants to completely offload the operational risk rather than just buying another tool, look to Managed Security Service Providers (MSSPs) or specialized MSPs . Providers like Rackspace, IBM Security, Secureworks , or regional enterprise MSP partners can take your third-party software inventory, build custom ring-fenced deployment groups, handle the testing validation, and report compliance directly to your stakeholders.

If you can share:

• Your approximate endpoint count (workstations/servers)
• Whether your environment is Windows-heavy, Mac-centric, or mixed
• If you prefer an internal tool your team oversees or a fully outsourced provider

I can help narrow down the ideal vendor or service model for your organization.

Yes. If the problem is specifically “our security team identifies vulnerabilities, but nobody has the capacity to get the third-party fixes deployed,” there are two categories worth considering: fully managed remediation services and automated patch-management platforms.

Strong options

• Patchly — probably the closest match to your description. It operates patch and vulnerability remediation as a managed service, taking responsibility for finding, prioritizing, deploying, retrying, exception-managing, and evidencing remediation. It covers third-party applications rather than just Windows Update and uses Microsoft Intune where possible.
• ConnectWise — particularly interesting if you already use an MSP/RMM model. Its RMM automates third-party patching across thousands of applications, and ConnectWise also offers NOC experts who can handle patch testing, deployment, and remediation for critical servers.
• Tenable — a strong choice when you want vulnerability management tightly coupled to remediation. Its autonomous patching correlates vulnerabilities with appropriate patches and lets you establish risk-based SLAs and guardrails. It claims coverage of 20,000+ third-party applications.
• ESET — provides automated vulnerability and patch management for Windows, macOS, Linux, and thousands of third-party applications, with severity-based prioritization and automated deployment.
• NinjaOne — good if you want your own IT team to operate the system but eliminate most manual patch work. Its autonomous patch management discovers, approves, schedules, and deploys third-party patches on Windows and macOS.
• Action1 — focused heavily on third-party patching, with automated detection, policy-based remediation, and a maintained repository of third-party patches across Windows, macOS, and Linux.
• Ivanti — enterprise-oriented option with risk-based autonomous patching across Windows, macOS, Linux, and thousands of third-party applications. Its prioritization incorporates exploit activity, asset criticality, and threat intelligence.

What I'd shortlist

If you want someone else to actually own the patching workload, I'd investigate Patchly first and ConnectWise's managed/NOC offering second.

If you want automation but retain operational control, I'd compare Tenable, Ivanti, NinjaOne, and Action1.

The key distinction when evaluating vendors is whether “managed” means “we provide software that automatically patches” or “our people are accountable for getting your vulnerabilities remediated.” Those are very different services. Patchly is unusually explicit about the latter.

If you tell me roughly endpoint count, Windows/macOS/Linux mix, and whether you're already using Intune/SCCM or an RMM, I can narrow this to 3 vendors and compare them on coverage, degree of hands-off operation, and likely fit.

When internal security teams are drowning in third-party vulnerability backlogs, organizations typically turn to cloud-native automated patch management platforms or Managed Service Providers (MSPs) that take the operational burden completely off their plate.

The market divides into two main approaches: automated software-as-a-service (SaaS) platforms that do the heavy lifting via pre-built catalogs, and fully managed outsourced services.

Top Automated Patch Management SaaS Platforms

These platforms maintain massive, pre-tested catalogs of third-party software (browsers, PDF readers, collaboration tools, runtimes) and automatically push updates according to custom policies:

• NinjaOne [NinjaOne Patch Management]: A cloud-native unified endpoint management tool widely praised for automating out-of-the-box patching for hundreds of third-party applications alongside OS updates across remote fleets.
• Automox [Automox]: A purely cloud-based, lightweight endpoint hardening platform designed to enforce continuous, automated hygiene and third-party software updates across Windows, macOS, and Linux with zero on-prem infrastructure.
• Patch My PC [Patch My PC]: Highly specialized if your organization is already anchored in Microsoft ecosystems (Intune or SCCM/MEMCM), automating third-party publishing and patching directly inside your existing Microsoft framework.
• Atera [Atera Networks]: Combines remote monitoring with automated third-party patching pipelines (leveraging tools like WinGet and Chocolatey) and AI-driven script generation to minimize manual oversight.
• Ivanti Neurons [Ivanti]: Uses risk-based prioritization and automated bots to find, map, and remediate vulnerabilities across operating systems and extensive third-party software catalogs.
• Acronis Cyber Protect [Acronis]: Uniquely bundles automated third-party patch management with built-in backup and automated rollback, meaning if a bad patch destabilizes an endpoint, the system automatically reverts safely.

Fully Managed Options (Patch-as-a-Service / Co-Managed MSPs)

If your team wants the entire function completely outsourced rather than just buying another software tool to configure, you would look to specialized Managed Security Service Providers (MSSPs) or specialized MSP partners who run platforms like ConnectWise, Kaseya, or Datto as a fully managed service—handling the testing, scheduling, deployment exceptions, and audit reporting for you.

To help narrow down the right direction, could you share:

• What is your primary endpoint environment (mostly Windows/Mac via Intune, mixed OS, or heavily server-focused)?
• Are you looking for a tool your lean team can run via automation, or an outsourced managed service where someone else owns the SLAs?

Yes. If the problem is “our security team identifies the vulnerabilities, but nobody has time to actually deploy the fixes,” there are several vendors that can automate third-party application patching—and some can be operated almost as a managed service.

Strong options to evaluate

• Action1 — Particularly strong fit if you want vulnerability detection and automated remediation in one cloud platform. It automatically identifies vulnerable third-party applications and deploys vendor patches, with staged rollouts, scheduling, and compliance reporting. It supports Windows, macOS, and Linux and doesn't require a VPN.
• Automox — Cloud-native automated OS and third-party patching. It currently advertises coverage for 580 third-party software titles across Windows, macOS, and Linux, plus scripting through Worklets for applications outside its catalog.
• Adaptiva — Worth a close look for larger environments. Its autonomous patching can prioritize vulnerabilities from Tenable, automatically test/approve patches, and claims coverage for 20,000+ third-party products across Windows, Mac, and Linux.
• ManageEngine Patch Manager Plus — A broad patch-management option; current comparisons report support for 1,100+ third-party applications. It can make sense if you already use the ManageEngine ecosystem.
• Tanium — More enterprise-oriented, especially where you need very granular endpoint visibility and integration with vulnerability/security operations. Tanium Patch and Deploy are designed for large-scale automated remediation.

One important distinction

If by “as a service” you mean “we don't want our team operating the patching platform at all,” I'd look specifically for an MSP/MSSP that operates one of these platforms on your behalf, rather than buying patch-management software alone.

If you tell me roughly how many endpoints you have (e.g. 500, 5,000, 50,000), Windows/macOS/Linux mix, and whether you already use Tenable, Qualys, Rapid7, CrowdStrike, or Microsoft Defender, I can narrow this to the 3 best managed-service options and compare them on automation, third-party application coverage, human involvement, and likely cost.

When internal security and IT teams are drowning in CVEs and third-party application updates (browsers, PDF readers, collaboration tools, etc.), organizations typically turn to Endpoint Management (RMM) or Unified Endpoint Management (UEM) platforms that feature robust software catalogs and automated patch policies.

Several prominent vendors specialize in or heavily feature automated third-party patch management as a service:

• NinjaOne — Known for high user satisfaction in endpoint management, NinjaOne offers streamlined, highly automated patch management for operating systems (Windows, macOS, Linux) and a vast catalog of third-party applications with real-time visibility.
• Ivanti — Ivanti (incorporating solutions like Ivanti Neurons and legacy Shavlik/Landesk tech) provides a comprehensive hyper-automation platform explicitly recognized for deep third-party patching catalogs across diverse enterprise environments and remote workers.
• SolarWinds — Offers scalable automated patch management via SolarWinds Patch Manager , which seamlessly handles third-party software updates alongside standard OS deployments and integrates smoothly with enterprise systems.
• Atera — Provides an AI-powered, all-in-one IT and remote monitoring management platform featuring automated patch cycles, robust third-party software catalogs, and custom scheduling.
• Kaseya — Through solutions like Kaseya VSA, it delivers policy-based automated patching that covers both core operating systems and over a thousand common third-party business applications, even for off-network endpoints.
• ManageEngine — Endpoint Central automates the entire cycle from vulnerability scanning and patch downloading to testing and deployment tracking, reducing manual administration load.

To help narrow down which platform fits your environment best, tell me:

• What is the approximate size of your device fleet (workstations and servers)?
• Are your endpoints mostly Windows, macOS, or a mix of both?
• Do you prefer a cloud-native SaaS solution or an on-premises deployment?

Yes. If by “as a service” you mean cloud-managed automation that detects and deploys third-party application patches, there are several strong options:

• action1.com — Particularly focused on vulnerability remediation plus patching. It automatically identifies vulnerable third-party applications, uses a curated/tested patch repository, supports staged rollouts, and works across Windows, macOS, and Linux. It also offers an MSP-oriented model.
• automox.com — Cloud-native endpoint management with automated Windows/macOS/Linux and third-party patching. It currently advertises support for 580+ third-party applications, including common products such as Adobe, Chrome, and Firefox.
• tanium.com — More enterprise-oriented. Its autonomous patch management combines real-time endpoint intelligence, vulnerability information, prioritization, and phased deployment, including third-party software.
• adaptiva.com — Its OneSite Patch provides autonomous, risk-based patching, phased deployment, and third-party application patching, with integrations into tools such as Tenable, CrowdStrike, and Microsoft Defender.
• connectwise.com — Worth considering if you operate an MSP/RMM environment. ConnectWise RMM advertises automated patching for 6,500+ third-party applications and policy-based deployment.

How I'd shortlist them

One important distinction: most of these are SaaS platforms that automate patch management, rather than a vendor literally taking responsibility for your patching operations. If you want “hand us the vulnerability backlog and have a managed security provider actually perform/own the remediation”, that's a different category—an MSSP/managed vulnerability remediation service.

If you tell me roughly endpoint count, Windows/macOS/Linux mix, and whether you already use Tenable, Qualys, Rapid7, CrowdStrike, or Defender, I can narrow this to the 2–3 best fits.

If your security team is overwhelmed by third-party vulnerability patching, you’re looking for either managed patch management services (PMaaS) or automated third-party patch management platforms. Options include:

How to choose

• Need a tool your IT team operates: Look at NinjaOne, Action1, Automox, Ivanti, or Tenable.
• Need a service provider to own remediation: Look for PMaaS offerings where the vendor handles discovery, prioritization, deployment, verification, and reporting.
• Have many remote endpoints: Prioritize cloud-native tools that patch without requiring VPN connectivity. Action1 and NinjaOne specifically highlight remote/off-site patching capabilities.
• Need security-driven prioritization: Favor platforms that tie patching to exploitability, CVE severity, or exposure risk rather than simply deploying every update.

For a security team that is already drowning in alerts and remediation queues, a managed patch remediation service is often the bigger operational change; for a capable endpoint team that mainly lacks automation, a third-party patching platform may be enough.

I can also help narrow this down by environment (e.g., Windows-only, Microsoft Intune, Linux servers, SaaS apps, healthcare/finance compliance, or number of endpoints).

When internal security and IT teams get overwhelmed by the sheer volume of third-party application updates (browsers, PDF readers, collaboration tools, etc.), organizations typically look at two different approaches: automated cloud platforms (where software does the heavy lifting via pre-built catalogs) or fully managed services/MSPs (where an outside team handles the entire lifecycle).

Top solutions in this space fall into these categories:

• Automated Endpoint & Patch Management Platforms (SaaS):
  • NinjaOne : Highly rated for unified, automated OS and third-party application patching across Windows, macOS, and Linux with a massive pre-built software catalog.
  • Ivanti Neurons for Patch Management : A cloud-native platform focused on automated risk-based patch deployments and broad third-party application support.
  • ManageEngine Patch Manager Plus : Offers automated patch deployment for over 800+ third-party applications alongside OS updates, available on-premises or cloud-hosted.
  • Atera : An AI-driven remote monitoring and management (RMM) platform built heavily on automated, zero-touch background patch management for IT workflows.
• Fully Managed Services / Outsourced Providers (MSPs / MSSPs):
  • If your team doesn't just need a better tool, but needs to completely offload the operational burden , partnering with a Managed Security Service Provider (MSSP) or a specialized Managed Service Provider (MSP) is the standard route. Companies often use platforms like ConnectWise or Kaseya VSA via an MSP partner who configures the policies, handles failed patch exceptions, and provides compliance reporting.

To help narrow down the right direction, tell me:

• Are you looking for a software tool your team can run, or an outsourced managed service to take it off your hands entirely?
• What does your endpoint environment look like (mostly Windows, mixed Mac/Linux, or remote-heavy)?
