Why SIEM is required?

  • SIEM tools are designed to use the log data to generate insights into past attacks and events.
  • A SIEM identifies an attack that has happened and checks how and why it happened.
  • SIEM detects attack activity and assesses the threat based on the past behavior of the network.
  • A SIEM system provides the ability to distinguish between legitimate use and a malicious attack.
  • SIEM tool also allows to increase a system’s incident protection and avoid damage to network structures and virtual properties.
  • SIEM tool also helps companies to comply with a variety of industry cyber management regulations.
  • SIEM systems provide the best way to meet this regulatory requirement and provide transparency over logs.

How much does SIEM cost?

SIEMs are deployed across various industries: financial, healthcare, retail, and manufacturing sectors, which all cover various types of cost structures. Here are the cost which is associated with any SIEM system.

  • Hardware: SIEM appliance costs or server costs for installation
  • Software: It covers the cost of SIEM software or agents for data collection
  • Support: Regular annual costs of maintenance of software and appliances.
  • Professional Services: It includes professional services for installation and ongoing tuning.
  • Intelligence Feeds: Threat intelligence feeds which provide information on adversaries

How does SIEM work?

A SIEM mainly works with closely related purposes: to collect, analyze, store, investigate, and develop reports on log and other data. These reports are used for incident response, forensics, and regulatory compliance purposes.

It also helps you analyse the event data in real time, allowing for early detection of targeted attacks, advanced threats, and data breaches.

Incorporated threat intelligence helps advanced analytics to correlate events that could signal a cyberattack is underway. The system will alert you about the threat and suggest responses to mitigate the attack, like shutting down access to data or machines and applying a missing patch or update. If you’re interested in even more advanced and proactive solutions, consider checking out some of the best cybersecurity companies that can offer comprehensive protection measures tailored to your specific needs.
