A managed security service is a set of functions carried out by a cybersecurity provider, usually on an annual basis. It allows businesses to outsource security functions instead of hiring full-time staff and maintaining their own team.
The service may include round-the-clock all-hours monitoring and management of firewalls as well as intrusion detection systems and patch management. It could also include vulnerability scanning, incident response, and digital forensics. It may also include virtual private networks (VPNs) and other security measures that protect data and devices. Many MSSPs are value-added resellers who specialize in managed security, or offer it as a part of their existing IT service. Some MSSPs specialize in offering security solutions directly to small and medium-sized businesses.
It is important to select the right managed service, as it can reduce the possibility of an organization being attacked, improve its cybersecurity posture, and ensure compliance. When choosing a security partner, look for an organization that is proactive in their approach to security and provides support throughout the day.
One example of an effective service is user behavior analytics, or UBA. This technique is utilized for establishing a baseline of the normal behaviors within an organization and then comparing every action against the baseline to identify anomalies.
The best MSSPs are able to learn about the company and provide a clear view of the organization to give specific guidance to limit the success of attackers, respond quickly and with confidence if an incident occurs, and increase the security of an organization. This includes analyzing and comprehending information and delivering alerts that can be actionable to stop threats, minimize risks and improve and fine-tune security programs to ensure it is sustainable.
