Suricata Newsletter for June 2025

Welcome

Hello and welcome to the June issue of the Suricata Newsletter! The Suricata development team has had their heads down working hard on the upcoming Suricata 8.0 release with the first beta and release candidate out.

Please consider subscribing to this newsletter by email, to do so head on over to https://newsletter.suricata.io/ and enter your email address.

Message from the OISF President

As we prepare for Suricata 8.0 and SuriCon 2025, we’re also focused on growing the OISF Consortium and global Suricata community. Being part of the Consortium isn’t about “sponsorship”—it’s about license compliance, supply chain due diligence, and directly funding the expertise behind Suricata’s development.

If your organization relies on Suricata, now’s the time to help shape its future. Reach out to me or info@oisf.net—we’ll show you how easy it is to join.

– Kelley Misata, PhD
President, OISF
