What is 0patch?

0patch is a microscopic solution for a huge security problem.

It provides miniature patches of code (“micropatches”) to computers and other devices worldwide in order to fix software vulnerabilities in various, even closed source products. With 0patch, there are no reboots or downtime when patching and no fear that a huge official update will break production.

Corporate users and administrators appreciate the lightness and simplicity of 0patch, as it is shortening the patch deployment time from months to just hours. Reviewing tiny 0patches is cheap, and the ability to instantly apply and remove them locally or remotely significantly simplifies production testing.

Software patching becomes virtually imperceptible.

Patching what’s really important

It would be almost impossible to eliminate all the errors in applications, so we are carefully selecting our micropatching targets to:

How does it work?

We are reinventing software patching.

0patch Agent, our mighty little patching machine, watches over all processes running on the computer. When any one of them is found to have a patch available, that patch is immediately applied to the process in memory without disturbing that process.

0patch Agent periodically asks our server whether it has any new patches to deliver, and downloads these patches so they’re ready to get applied to vulnerable processes. These patches are immediately available even if you install a vulnerable product on a computer that is not connected to the Internet at the time.

0patch does not replace executable files or modify them in any way. It corrects them only in memory of processes that use these executables, which can be done without relaunching them.

Micropatches for Windows 7
and Server 2008 R2

Worried about security patches for your Windows 7 and Windows Server 2008 R2 computers after their support has ended in January 2020? Don't be. 0patch provides security micropatches for high-risk vulnerabilities in these popular and ubiquitous Windows platforms, all included in the price of a PRO license that already gives you many micropatches for other high-risk vulnerabilities in various widely used products.

No matter if home or business user, small shop, enterprise or government - we have you covered. As an added bonus, you don't have to restart your computers (or even lift a finger really) to get patches applied, they take just a few bytes of your space and get downloaded in seconds.

Micropatching the future

Empowering security researchers

0patch aims to completely change the game by channelling the knowledge of security researchers, who could so far only write or speak about discovered vulnerabilities and develop exploits for them, into directly solving the problem.

As a community, we're accumulating knowledge about 3rd-party patching and sharing it with our existing and future members. We're building an important component of Internet's global immune system of tomorrow, where personal computers, servers, tablets, phones and billions of IoT devices will be in constant dire need of rapidly deployable security fixes.
