Managed Security Service Provider (MSSP)

provides outsourced monitoring and management of security devices and systems.

Common services include managed firewall, intrusion detection, virtual private network, vulnerability scanning and anti-viral services.

MSSPs use high-availability security operation centers (either from their own facilities or from other data center providers) to provide 24/7 services designed to reduce the number of operational security personnel an enterprise needs to hire, train and retain to maintain an acceptable security posture.
