What Is a Managed Security Service?

A managed security service is a collection of services performed by a cybersecurity service provider, often on the basis of subscription. It allows businesses to outsource security tasks instead of hiring full-time employees, and also maintaining their own team.

The service may include round-the-clock monitoring and management of firewalls, intrusion detection systems as well as patch management, vulnerability scanning and incident response, as well as digital forensics. It may also include the virtual private network (VPN) and other security devices to protect devices and data. Many MSSPs are value-added resellers who specialize in managed security, or offer it as part of their existing IT service. Some MSSPs focus on offering security solutions directly to small and medium-sized enterprises.

It is important to choose the right managed service, since it can lower the chance of an organization being targeted, improve its cybersecurity level, and help ensure compliance. When choosing a security partner, choose an organization which is proactive in their approach to cybersecurity and provides 24/7 support.

One example of a successful service is user behavior analytics, also known as UBA. This method is employed to establish a baseline for the typical behavior of the network, and then comparing the new actions against that baseline to find anomalies.

The best MSSPs learn and gain insight into the environment, so they can provide specific guidance to minimize attacks, react quickly and with confidence in the event of an incident, and improve the security position. This includes analyzing and comprehending information and delivering alerts that can be actionable to avoid threats, limit risks, and optimize and fine-tune a security program for the long-term.
