Hello,
I am security professional in SOC environment I have been worked with HP Arcsight, ELK and waiting for a stable version Apache Metron to use in production. As Metron comes from Telemetry, may be the logo should highlight this with something related to an antenna (or two with the two spikes of the M). Example of Antenna with radio waves: [image: Inline image 1] Otherwise between the 5 logos proposed I prefer 4 because for me it illustrates better the purpose of Metron. The first one highlights more Security but the castle is more for protection/prevention. Metron will not protect/prevent anything: it will give you a lot of information to be able to take decision and protect your environment. [image: Inline image 1] Kudos to all people involved in this exciting project there is a real need for an OpenSource SIEM (or security analytics) with bigdata and Machine Learning support.
