AAction1 develops cloud software that helps IT teams manage device updates and remediate vulnerabilities across distributed organisations. Its platform uses endpoint agents and a browser console to identify missing patches, deploy operating-system and third-party application updates, and report deployment status. Administrators also use it for software deployment, inventory, scripting and remote desktop access, serving both internal IT departments and managed service providers. The business earns subscription revenue through per-endpoint licences, with hosted infrastructure replacing the need for customers to maintain their own patch-management servers. Founded in 2018, Action1 is headquartered in Houston, Texas.

Action1 introduces industry-first Endpoint Takeover Prevention architecture. New security architecture prevents threat actors from taking over customer endpoints, even if the Action1 platform is compromised. Action1, a leading provider of autonomous endpoint management (AEM) solutions, announced Endpoint Takeover Prevention (ETP), an industry-first security architecture that prevents threat actors from using a compromised endpoint management platform to take control of customer endpoints. With ETP, high-risk endpoint actions such as running scripts, deploying software, and opening remote sessions require a cryptographic signature from the customer. Even if threat actors compromise the Action1 platform, they cannot authorize high-risk actions on customer endpoints without the customer's private key. Built for the era of AI-driven cyber attacks, Action1's ETP protects customer endpoints against unauthorized takeover. Until now, endpoint management has relied on endpoints implicitly trusting and executing commands they receive from the management platform. This has created a long-standing, industry-wide security risk: compromising a single platform could give threat actors control over millions of endpoints across thousands of organizations. This risk is far from theoretical. The 2020 SolarWinds Orion supply chain breach and the 2021 Kaseya VSA ransomware attack demonstrated how enterprise IT management software can expose organizations to large-scale cyberattacks. Following the March 2026 cyberattack against Stryker, CISA urged organizations to harden their endpoint management systems. More recently, the critical PHP2Shell vulnerabilities exposed another potential path for attackers to compromise enterprise software. AI is making this long-standing risk even more urgent. As Anthropic demonstrated with Claude Mythos Preview, advanced AI models can autonomously discover previously unknown vulnerabilities and develop working exploits, dramatically accelerating the potential pace of cyberattacks. Oct 28, 2026 Prev Next 1 of 43,968 While AI makes it increasingly difficult to keep attackers out, traditional security measures such as MFA, role-based access control, and zero-trust policies remain essential. But they do not address the underlying risk: endpoints continue to trust and execute commands from the management platform, even if it is compromised. ETP fundamentally changes how enterprise endpoint management platforms operate. Instead of automatically trusting commands from the management platform, endpoints managed by Action1 execute high-risk actions only when the customer cryptographically authorizes them. Even if threat actors gain complete control of the Action1 platform, they will not be able to execute high-risk actions on customer endpoints. Action1 is the first endpoint management vendor to offer this level of protection. "Customers trust their endpoint management vendor with every endpoint, but that trust should not become their biggest exposure," said Alex Vovk, CEO and Co-Founder of Action1. "Yet that's exactly the risk the industry has accepted for decades. With ETP, we're changing the rules. Even if our platform is compromised, threat actors cannot use it to take over customer endpoints. We believe this should become the new standard for endpoint management, because no vendor, including Action1, should be a single point of failure for its customers." How ETP Works * Customer-controlled authorization: Private keys remain under customers' cryptographic control. Action1 cannot authorize high-risk actions on their behalf. * Independent endpoint verification: Action1 endpoint agents verify cryptographic signatures and block unauthorized or altered commands. * Protection of high-risk endpoint actions: ETP covers automations, scripts, software packages, data sources, agent control operations, and remote sessions. * Autonomous operation: Authorized automations and scheduled deployments continue running without requiring manual approval for every execution.

Action1 has launched two new endpoint management modules: Endpoint Configuration Management and Endpoint Enrollment and Provisioning. The separately licensed additions help IT teams rapidly bring Windows endpoints under management and maintain secure configurations. The Endpoint Enrollment and Provisioning module enables organisations to quickly enrol selected Windows endpoints through Microsoft Intune and immediately apply software, vulnerability remediation, and configuration policies. The provisioning feature runs assigned automations to deploy software, patch vulnerabilities, and apply configuration policies from a single console. The Endpoint Configuration Management module addresses configuration drift by allowing organisations to define policies using established security frameworks, including Microsoft Security Baselines, CIS, DISA STIGs, and NIST. Policies can be assigned to endpoint groups in assessment-only or assessment-and-remediation mode. Both modules are available as separately licensed additions to Action1's platform and are not included in the standard licence.
Action1, a provider of autonomous endpoint management solutions, has been named the fastest-growing founder-led cybersecurity company on the 2026 Inc. 5000 list for the second consecutive year. The Houston-based company reported 4,512% three-year revenue growth. The firm's cloud-native patch management platform helps organisations manage security updates across thousands of endpoints without manual work or on-premises infrastructure. The first 200 endpoints are offered free with no functional limits. "We started Action1 with a vision of a world where cyberattacks exploiting vulnerabilities are entirely prevented," said Mike Walters, president and co-founder. The company maintains a 98% customer retention rate. Action1 was founded by industry veterans Alex Vovk and Mike Walters, who previously founded Netwrix.
Action1 is America's #1 fastest-growing founder-led cybersecurity company on the Inc. 5000 for the second consecutive year. Houston, Texas, August 13, 2026 Action1, a leading provider of autonomous endpoint management (AEM) solutions, today announced it has been named to the 2026 Inc. 5000, the annual ranking of the fastest-growing companies in America, landing as the #1 fastest-growing founder-led cybersecurity company for the second consecutive year. The recognition underscores Action1's accelerating year-over-year growth and reflects surging demand for its autonomous approach to endpoint security and patch management, which helps thousands of organizations close security gaps before they can be exploited and lead to breaches. "We started Action1 with a vision of a world where cyberattacks exploiting vulnerabilities are entirely prevented across every device, operating system, and application," said Mike Walters, President and Co-founder of Action1. "Two years running on the Inc. 5000, backed by Action1's 98% customer retention rate, confirm that organizations increasingly rely on us to help get there." The company's 4,512% three-year revenue growth, driven by rising demand and growing customer trust, signals an industry-wide shift: as organizations retire legacy patch tools, Action1's cloud-native, autonomous patch management platform has become a go-to replacement.
