What we do

With over 40 years of experience there are few things we can't tackle

System Architecture

Networks and heterogeneous

environments are our passion. We love designing and building the perfect IT solution for you. We think outside the box and make just about anything work.

Security

pen testing and actual network attacks, we have the ability to get your network security in line with complete reporting and monitoring tools. We run elaborate Phishing campaigns against your employees to ensure they they aren't clicking on those emails.

Let Coherence Systems manage your I.T. infrastructure, you can rest assured that we will be monitoring your network 24/7 and running proactive tests and system diagnostics throughout the week. We don't wait for errors to pop up, we look for them

before they happen. Let us take the burden of managing I.T. off of you with dedicated staff who will be on-site as much as needed..

The Cloud
