As CTO of floragunn, I'm responsible for the architecture of Search Guard and leading the team of developers. Since I'm a coder at heart, I still enjoy contributing code and features to Search Guard.
Search Guard® is an Open Source security suite for Elasticsearch and the entire ELK stack that offers encryption, authentication, authorization, audit logging and multi-tenancy. Whether you just want to encrypt data in transit, authenticate users against Active Directory, use Kerberos or JSON web tokens for Single Sign On or need to monitor to log malicious access attempts, Search Guard is your one-stop solution.
