Why Connectivity
How Connectivity keeps systems current
Connectivity Core Security pairs skilled IT people with enterprise-class security software, centrally deployed and centrally managed. Patch management, version control, intrusion prevention, network vulnerability scans and dark web scanning are part of the standing scope of every managed agreement. Updates do not depend on employees clicking “install,” and keeping your network current does not depend on who remembers. You see the results in monthly reporting and at your quarterly business review.
