We have had numerous inquiries requesting information about the status of CTI networked products and
the LOGJ4 vulnerability widely reported.
LOGJ4 is a java-based logging utility that is part of the Apache web server infrastructure.
CTI C-Series PLCs are based on Integrity OS, do not support any Linux or Java based applications, and do
not use any Apache technology. There is no LOGJ4 vulnerability in these products.
Janus PLCs and other upcoming products based on the Janus technology use Linux, but do not use any
Java-based or Apache technology. There is no LOGJ4 vulnerability in these products.
For information about specific CTI products, see this
