Open source is a wonderful thing. A significant chunk of todays enterprise IT and personal technology depends on open source software. But even while open source software is widely used in networking, operating systems, and virtualization, enterprise security platforms still tend to be proprietary and vendor-locked. Fortunately, thats changing.
If you havent been looking to open source to help address your security needs, its a shameyoure missing out on a growing number of freely available tools for protecting your networks, hosts, and data. The best part is, many of these tools come from active projects backed by well-known sources you can trust, such as leading security companies and major cloud operators. And many have been tested in the biggest and most challenging environments you can imagine.
