Antivirus software tells you when it catches a known virus. But what about everything else: the failed login attempts at 3 AM, the unusual file transfer, the login from a country your business has never worked with? That is where SIEM comes in.
What Does SIEM Stand For?
SIEM stands for Security Information and Event Management. It is a system that continuously collects and analyzes security data from across your business, your computers, servers, firewalls, Microsoft 365, and other cloud services, and looks for patterns that suggest something is wrong.
How SIEM Works
Think of SIEM as a digital alarm system. Instead of one camera watching one door, SIEM pulls information from every entry point into your business at once: network traffic, email activity, user logins, and file access, and correlates it. When it spots something that looks suspicious, like a login from an unfamiliar location or a sudden spike in failed password attempts, it generates an alert so someone can investigate before it turns into a bigger problem.
Why Small Businesses in Austin Need SIEM
SIEM used to be a tool only large corporations and government agencies could afford, requiring dedicated security teams and expensive infrastructure. Cloud technology and managed services have changed that. Today, a small or mid-sized Austin business can get the same kind of visibility a large enterprise has, without building an internal security operations center from scratch.
SIEM vs. Antivirus: What Is the Difference?
Antivirus software looks for known threats on a single device. SIEM looks across your entire environment for patterns and behavior that indicate a threat, even one that has never been seen before. Most businesses need both: antivirus and endpoint detection and response (EDR) on individual devices, and SIEM tying the bigger picture together.
