Patch Management, the Way
IT Teams Wish It Worked
Continuously discover and prioritize missing OS (Windows, macOS,
Linux) and third-party updates across distributed endpoints. Deploy pre-tested patches to remediate vulnerabilities without a VPN - all from a cloud-native platform you can set up in five minutes with no on-premises
infrastructure.

Solving the patching problem
once and for all
Purpose-built for patching, Action1 replaces manual checks and disconnected
tools with a single autonomous workflow connecting missing-patch discovery,
deployment, and verified remediation.
Discover
Automate detection of Windows, macOS, Linux, and third-party patches.
Prioritize
Surface critical, known-exploited, and ransomware-linked CVEs.
Remediate
Remediate patchable vulnerabilities by deploying the updates that address them.
Verify
Coordinate reboots and verify remediation success.
Unified cross-OS
patch management
Patch your Windows, macOS and Linux endpoints through one cloud-native
workflow with no VPN on on-prem infrastructure required.
Windows
Automate security updates, cumulative updates, and Windows feature upgrades across Windows-based workstations and servers. Use policies and ring-based staged rollouts to reduce disruption and maintain compliance.
macOS
Identify missing macOS updates in real time, test patches on selected devices, and schedule deployment across your fleet without relying on manual update processes.
Linux
Automate updates across supported Debian, Ubuntu, Red Hat, and SUSE distributions. Keep Linux endpoints and servers secure without maintaining separate patching tools or workflows.
Third-party patching,
tested before you deploy
Unlike community-maintained repositories, PatchAssurance™ is a private, expert-curated catalog where supported application packages are sourced, tested, scanned, validated, and maintained by Action1 experts.
This gives IT teams greater confidence in what they deploy and a more dependable way to automate third-party updates, without tracking vendor releases or maintaining packages themselves.
Why IT teams
choose Action1 for patch
management
Deploy in minutes and automate the complete patching lifecycle - from discovering and prioritizing vulnerabilities to controlled rollout and verified remediation.
Up and running in 5 minutes
Deploy Action1 and start identifying missing updates without a lengthy implementation. Its cloud-native architecture requires no patch servers, appliances, VPN configuration, or additional infrastructure.
Real-time, risk-informed prioritization
See missing OS and third-party updates, affected endpoints, detected CVEs, deployment status, and remaining exposure in real time. Prioritize remediation using severity, CVSS scores, CISA KEV status, ransomware associations, and remediation SLAs.
Unified OS and third-party patching
Manage updates for Windows, macOS, Linux, and supported third-party applications from one console. Replace separate patching tools, custom scripts, and manually maintained deployment processes.
Trusted patches with PatchAssurance™
Deploy supported third-party updates from Action1's private, expert-curated patch catalog. PatchAssurance™ provides a controlled alternative to relying solely on public, community-maintained repositories.
Autonomous rollouts with a 99% success rate
Turn patching policies into recurring workflows with update rings, success thresholds, approvals, exceptions, maintenance windows, reboot controls, and automatic retries. Stage updates safely while reducing manual oversight and disruption.
Closed-loop vulnerability remediation
Move directly from CVE discovery to action without exporting vulnerability lists or switching tools. Deploy the appropriate patch, remove vulnerable software, document compensating controls, and verify remediation from the same platform.
Cloud-native patching at enterprise scale
Patch remote, hybrid, on-premises, and off-network endpoints without a VPN. P2P distribution shares update files within each local network, reducing duplicate downloads and external bandwidth consumption during large deployments.
Audit-ready proof of remediation
Track successful, failed, and pending deployments, missing updates, required reboots, and unresolved vulnerabilities. Create and schedule customizable reports and export audit evidence without assembling it manually.
First 200 endpoints free forever
Use the complete platform for your first 200 endpoints with no feature restrictions or expiration. Prove Action1 in a production environment before expanding it across the enterprise.
Global data residency for local compliance
Keep your Action1 data in the region that meets your organization’s residency and regulatory requirements, with hosting available in the USA, UK, Europe, and Australia. Action1 can rapidly expand to new regions as local requirements evolve.
Patching isn't a feature.
It's our focus.
