Specifications include, but are not limited to: A Managed Detection and Response (MDR) software and related services solution to protect our stakeholders from malicious cyber intent. APS needs visibility into what threat actors may be attempting and or successfully gaining access to on our systems in order to protect our stakeholders from malicious cyber intent. The solution should be able to detect actions outside of a normal baseline. We also need the solution to be flexible and customizable based on fast changing operational needs. We are looking to completely replace several legacy anti-virus and anti-malware solutions. We are looking to cover approximately 20,000 endpoints, split approximately 64% Windows, 35% MacOS, and 1% Linux. The software offered should support operating systems as far back as Windows 7, Windows Server 2008, and MacOS X. APS uses GPO, SCCM, and Mobile Device Management to push software out to endpoints and these methods must be supported by the MDR endpoint agent.
