Action1
Houston-based cloud-native patch management and RMM platform, free for organizations under 200 endpoints, founded by the team behind Netwrix to close the unpatched-vulnerability gap that drives most breaches.

Action1 sells autonomous, cloud-native patch management and remote monitoring and management (RMM), aimed squarely at the fact that unpatched software remains one of the most common initial-access vectors in real breaches. Its platform automates OS and third-party application patching, risk-based prioritization, and audit-ready reporting, and is built cloud-native rather than as an on-premises agent console, which simplifies deployment for distributed and remote workforces.
Founded in 2018 and headquartered in Houston, Texas, Action1 was started by Alex Vovk and Mike Walters, who previously founded and sold Netwrix, giving the company founders with a prior successful exit in the IT security tooling space. Action1 has grown its headcount substantially in the past two years, with third-party data showing growth from roughly 72 employees in mid-2025 to 130-plus by mid-2026, alongside reported annual revenue of around $12.7 million. The company has been recognized as a Leader in G2’s Endpoint Management category in both its Winter 2025 and Winter 2026 reports and holds a large base of user reviews on Capterra (over 230). A notable part of its go-to-market model is a free tier for organizations managing under 200 endpoints, a bottoms-up wedge into a market usually dominated by paid enterprise RMM tools.
For CISOs, Action1’s relevance is direct: patch management closes one of the highest-value, most exploited gaps in an environment, and Action1’s free tier and cloud-native model lower the barrier for smaller IT teams to get baseline patch hygiene in place without a large procurement cycle.
Innovation Matrix Assessment
Consecutive G2 Leader recognitions in Endpoint Management across Winter 2025 and Winter 2026 reports, combined with rapid headcount growth, point to sustained product investment and iteration.
Growing from roughly 72 to over 130 employees within about a year while reportedly reaching $12.7M in revenue on a largely bootstrapped basis reflects real operational scaling discipline.
Documented quarter-over-quarter headcount growth (26% then 16% in consecutive periods per third-party data) alongside repeat industry-analyst recognition indicates strong, currently accelerating momentum.
A free tier for organizations under 200 endpoints is a genuinely disruptive bottoms-up go-to-market move in a market historically dominated by paid, procurement-heavy RMM and patch tools, expanding access for smaller IT teams.
Over 230 Capterra reviews and consecutive G2 Leader badges are independently sourced satisfaction signals, though they fall short of a formal red-team, MITRE-style, or third-party security efficacy evaluation.
Patch management addresses one of the most consistently exploited initial-access vectors in real-world breaches, keeping it a persistently high-priority control for essentially every CISO.
Why CISOs Should Care
Action1 removes a common barrier to good patch hygiene, cost and deployment complexity, by offering a free, cloud-native tier for smaller environments and a proven, bootstrapped-to-scale product for larger ones.
What Makes It Different
Its free-under-200-endpoints model and cloud-native (agentless-friendly) architecture differentiate it from legacy on-premises RMM and patch tools that require heavier infrastructure and licensing commitments.
The Matrix Verdict
67/100 — INCREMENTAL INNOVATOR
A fast-growing, product-led patch management vendor with strong independent review signals and a disruptive freemium model, though formal third-party security efficacy testing is not yet part of its public evidence base.
Editorial Note: Claims vs. Verified Findings
G2 Leader recognitions and Capterra review counts are independently published third-party sources. Revenue (~$12.7M) and employee headcount figures come from third-party data aggregators (GetLatka, Tracxn, Caplight) rather than audited disclosures, and sources conflict on whether Action1 has taken any outside funding (GetLatka says bootstrapped; PitchBook/CB Insights reference a $20M round involving Tenable Ventures) — this discrepancy is unresolved and noted rather than picked arbitrarily.
