ModSecurity 2.5.9 x64 (64 bit) Windows Binary


Update: ModSecurity 2.5.11 is now available.

Now that I am using 64 bit version of the Apache HTTP Server, I also have to use 64 bit version of ModSecurity. I couldn’t find a 64 bit binary of the latest version (2.5.9 at the time of this writing), so I decided to compile it myself.

Anyway, I am posting this binary here for anyone else who needs it. I am currently using it with Apache 2.2.13 in Windows 7. It was compiled with Visual C++ 2008 (VC9), with libxml2-2.7.3 and lua-5.1.4.


CRC32: A5642466

MD5: E86DA5091B639CD5E8CEB1422D7101C1

    You need to put the libxml2.dll file in Apache’s “bin” directory.

    By the way, 32 bit binary for mod security is available at
