Fewer alerts: By using analytics and AI to correlate alerts and identify the most serious events, a SIEM cuts down on the number of incidents people need to review and analyze.Context: Because a SIEM collects data across all the technology in the organization, it helps connect the dots between individual incidents to identify sophisticated attacks.Log aggregation: A SIEM collects the log data and correlates alerts, which analysts use for threat detection and hunting.Without a SIEM it would be extremely difficult for a SOC to achieve its mission. This may be difficult for teams that don’t focus on security operations all day, every day. With regular training and well-documented processes, the SOC can address a current incident quickly-even under extreme stress. Because they are continuously monitoring the network and analyzing alert data, they are more likely to catch threats earlier than a team that’s spread among several other priorities. SOCs can also limit the business impact when an attack does occur.

Using its knowledge of the broader cybersecurity environment as well as its understanding of internal weaknesses and business priorities, a SOC helps an organization develop a security roadmap that aligns with the long-term needs of the business. Both attackers and the defense community frequently develop new technologies and strategies, and it takes time and focus to manage all the change.
