Sysdig launches open source cloud security community 

Stratoshark

The need for a unified community was made clear by the January 2025 launch of Stratoshark (a technology that Wireshark’s network visibility to the cloud by using Falco’s ecosystem) and began as the technical convergence of the two widely adopted tools. 

Wireshark has more than five million daily users with deep expertise in network analysis and troubleshooting and Falco has over 4 million users and 1,000 contributors skilled in advanced cloud threat detection. 

“The future of security is built on open source and I believe that as much today as I did more than 20 years ago when Wireshark was born,” said Loris Degioanni, Falco creator and Sysdig founder and CTO. “Threat actors are working together, sharing tactics, scripts and now AI techniques. Instead of fighting an asymmetrical battle, security professionals must do the same. Not only does the Sysdig Open Source Community create a space for them to collaborate and help shape the tools they use, but it delivers an open forum to share what they’re seeing on the frontlines and form a stronger, more collective defence.”

As we know, the open source security landscape is evolving rapidly. 

With growing complexity around cloud environments and a new wave of professionals entering the field, the need for a more connected, resource-rich space has never been greater.

Degioanni and team say that the Sysdig Open Source Community delivers a dedicated home for user collaboration across:

• Wireshark: The world’s leading network protocol analyser, launched in 1998 and downloaded over 160 million times in the last decade alone.
• sysdig OSS: The foundation of open source system visibility, specialising in cloud-native forensics and incident response, launched in 2014.
• Falco: The open source standard for threat detection and Cloud Native Computing Foundation (CNCF) graduated project used by 60% of the Fortune 500, launched in 2016.
• Stratoshark: Described as “Wireshark for the cloud,” the open source cloud forensics tool launched in early 2025 and has already reached more than 40,000 downloads.

In addition to the established user base across the Sysdig OSS ecosystem, the community will be upheld by nearly one hundred maintainers, threat researchers, engineers and support professionals from Sysdig. 

While there are many disparate channels for users to ask questions today, the Sysdig Open Source Community is designed to bring those conversations together – fostering deeper collaboration, knowledge sharing and a stronger sense of connection.

Questions, answers, best practices

Community members will be able to collaborate in forums for users of all four technologies, creating an easily-searchable record of questions, answers, best practices; they can also engage in certification programs that validate their security skills.

Users will be able to peruse job and freelance boards that connect them with career opportunities; participate in mentorship pairing designed to support both new and experienced professionals; explore a student support center full of resources to help new technologists break into the industry, or simply work through a problem or project.

“Open source isn’t just about lines of code. It’s about people and it’s about raising the security standard,” said Gerald Combs, Wireshark creator and Sysdig director of open source projects. “There are people who have used tools like Wireshark and Falco throughout their career and this community gives them a place to learn, innovate and raise the bar. From helping longtime Wireshark users transfer their expertise directly into the cloud, to helping new users learn the basics of OSS security, there is something for everyone in the Sysdig Open Source Community.”

Registrations to join the Sysdig Open Source Community are now open.
