The answer: All of the above.
SIEM benefit: Unified log collection
Break down silos and establish a single source of truth.
This one is nearly universal. Any SIEM system provides you with a single, detailed log of almost every bit of data moving around your business systems. There are no more issues with silos, as every log from every connected system is replicated on the SIEM, and usually in real time. If you need to track something, you can do it from here.
SIEM benefit: Faster incident response
Detect and respond in real time with correlation and automation.
Modern SIEM systems do more than log logs. They analyze that data in real time, looking for anomalies, weaknesses, and patterns associated with unwanted access. Because the system correlates events from all over your system, it can both spot unwanted data manipulation more quickly and it can track unauthorized users as they move through your systems.
SIEM benefit: Compliance and audit readiness
Pre-built dashboard, retention policies, and immutable logs.
Almost all SIEM systems come with canned reports and pre-configured dashboards. These contain all of the factors that businesses and other organizations need to see, and are a great place to start when designing your own custom reports and dashboards.
SIEM benefit: Threat-hunting enablement
Dig deeper with advanced query language and saved searches.
Many of the best SIEMs have their own query languages that let you speed up complex searches and even some remedial fixes. Bespoke queries and search tools let you parse mountains of data very quickly, filtering out only those anomalies or detections that interest you at one particular moment.
SIEM benefit: Business risk reduction
Minimize breach costs and reputational damage.
Simply put, data breaches and cybersecurity attacks cost you money. Sometimes huge amounts of it, and not just in terms of assets compromised or destroyed, or even compensation to your customers. They are hits to your most vital and irreplaceable asset—your reputation. A good SIEM system can dramatically reduce the risk of a data breach from occurring, and can reduce the severity and duration of that breach if it does occur. It’s almost certain to save you more money than you could spend on it.
For most organizations, ROI isn’t exactly easy to gauge. More than two-thirds (71%) report finding ROI somewhat or extremely difficult to measure. Only 28% find identity protection ROI not at all difficult to measure.
