Computer Service Ann Arbor, Ann Arbor Computer Service

Do you know how your network is setup?

Are you up-to-date on cybersecurity threats?

Do you have all the necessary protection to keep harmful viruses and hackers out?

Here are 3 questions that most people don't ask about, but should:

  1. Are we secure?
  2. Is our data backed up?
  3. What do we need to do maintain our technology, and keep it running well, so our users can be productive?

At Network Services Group, we offer many services to ensure your business is running in tip-top shape. 

One such service is a network security review.  Here is a list of things to check to keep your small business network safe and secure:
