Suricata boosted:

With #Suricata Language Server 1.2.0 it will be possible to check the signatures in the file against a PCAP file. You will instantly know if the signature match and what is its CPU cost. Check the video for a demo of the feature.

Suricata boosted:

Rules profiling in #Suricata Language Server is now pushed to main branch. Current default Suricata image from @ish should have rules profiling when https://github.com/jasonish/docker-suricata/pull/53 get merged. For now, only local Suricata with correct build will provide profiling.

Suricata boosted:

Ok, #SuriCon2025 is over. Each time I join the #suricata team and community I'm amazed and in awe at how crazy nice this crowd is. As my colleague Peter Mane often says, I'm grateful for being here and a part of this. Hope to see many more folks in Lisbon next year!

- specify test pcap and see from editor if the signature hits
You can use main branch to test it if you are in the mood: https://github.com/StamusNetworks/suricata-language-server
