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.

Automate detection of Windows, macOS, Linux, and third-party patches.

Surface critical, known-exploited, and ransomware-linked CVEs.

Remediate patchable vulnerabilities by deploying the updates that address them.

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.

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.

Identify missing macOS updates in real time, test patches on selected devices, and schedule deployment across your fleet without relying on manual update processes.

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.

See how Action1 compares with other products and approaches across the complete workflow - from discovery and risk prioritization to controlled patch rollout and verified remediation.
