A few weeks ago Gartner released its annual Hype Cycle for Infrastructure Protection, 2016. It’s an impressive and exhaustive guide to the wide range of threat-facing technologies that help defend IT. Included among these technologies is Network Security Policy Management (NSPM) tools, which Gartner gives a benefit rating of ‘High’ – which in Gartner terms means that the technology “Enables new ways of performing horizontal or vertical processes that will result in significantly increased revenue or cost savings for an enterprise”.
During a merger or acquisition, you have two enterprises each running complex IT infrastructures with hundreds if not thousands of applications. Usually, these applications don’t just simply integrate together – rather, some perform overlapping functions and need to be altered or extended; some need to be used in parallel; while others need to be decommissioned and removed. This means adjusting firewall policies to accommodate the new connectivity, new applications and new servers and often new firewalls without creating IT security risks or outages.
