ACROS Security announced 0patch PRO on April 2, 2019, as a paid service for applying small code changes—called micropatches—to vulnerable Windows software. ACROS positioned it as a way to address selected security gaps while waiting for a vendor fix or after a product reaches end of support. The launch is historical; the plan details and prices below are a dated snapshot from ACROS’s August 2026 article, not a guaranteed current quote.
What 0patch PRO is—and what ACROS announced in 2019
ACROS Security’s April 2, 2019 launch announcement introduced 0patch PRO as a commercial micropatching platform for Windows software, aimed at enterprises and individuals. The release described a micropatch as a microscopic piece of binary code that replaces a vulnerable part of a program.
ACROS said the service could be used to address zero-day vulnerabilities, issues without an available vendor patch, selected end-of-life products, third-party components, and customized software. Those are the company’s stated use cases, not an independent assessment that every application or vulnerability can be patched.
The company framed micropatching as a way to reduce the time systems remain exposed when conventional security updates are delayed. Its statements about shrinking update gaps and protecting systems before official fixes were product positioning, not independently measured results.

How micropatching is intended to work
Rather than waiting for a software vendor to issue a full update, 0patch applies a small code change intended to replace or mitigate the vulnerable behavior. ACROS’s current 0patch homepage describes miniature patches for software vulnerabilities, including in closed-source products, and presents legacy systems and zero-day vulnerabilities as use cases.
ACROS also promotes applying patches without reboots or downtime. Treat that as a vendor claim: the cited materials do not provide independent comparative testing or establish that every patch can be applied with no disruption in every environment.

How PRO and Enterprise differ in ACROS’s August 2026 description
ACROS’s August 24, 2026 Office 2021 article describes two paid plans. Both are presented as including all security patches; Enterprise adds central administration and organization-wide controls. The following comparison reflects that dated vendor description.
| Plan | Intended audience | Management | Annual price per computer |
|---|---|---|---|
| PRO | Individuals and small businesses | Management on each computer | €24.95 plus tax, per computer per year (ACROS, August 2026) |
| Enterprise | Medium and large organizations | Central management, user roles, device groups, group-based patch policies, and single sign-on | €34.95 plus tax, per computer per year (ACROS, August 2026) |
These prices are ACROS-reported figures from August 2026, not a guaranteed current quote. Check the official 0patch site for current availability and pricing before purchasing. ACROS’s partner FAQ says a license is required for each computer or device running the agent; separate virtual instances count separately.
What the 2019 launch coverage said about PRO
A contemporaneous SecurityWeek report from April 2, 2019 described additional PRO-only fixes and email support at launch, while saying zero-day patches were available to both FREE and PRO users. It reported a launch-era price of $25.95 plus tax per agent per year. That 2019 price and feature division should not be substituted for ACROS’s later, dated plan description.
Use case: patching software that remains necessary
Micropatching may be worth evaluating when an organization still depends on software that is unsupported, awaiting an official fix, or difficult to update promptly. For example, ACROS said in its August 2026 Office 2021 article that it planned to provide critical Office 2021 security patches beginning in October 2026 for at least three years, with a possible extension if demand warranted. That is ACROS’s plan, not a guarantee from an independent authority.
Rank #4
The same August 2026 article said the FREE plan covered vulnerabilities that did not yet have an official vendor patch, but did not include the planned post-October 2026 Office 2021 security coverage. That description is specific to ACROS’s dated article; it should not be read as a permanent definition of FREE.
Before relying on a micropatching service, check whether your exact application and version are covered and whether the approach fits your operational and security requirements. Also consider vendor support status, compatibility with essential legacy applications, deployment and reboot requirements, fleet-management needs, support scope, and total licensing cost. The cited sources do not independently establish comparative effectiveness or suitability for any particular environment.
Who can explore a partner relationship
ACROS’s partner page invites applications from MSP/SOC, reseller/distributor, and technology partners. The page establishes that these partner categories can apply; it does not establish commissions, referral terms, or acceptance conditions.
