Hello Splunk users. Splunk for fast processing of big data. It is also widely used in the field of increasingly sophisticated cyber security. Gartner's Magic Quadrant for SIEM (Security Information and Event Management) product categories has positioned Splunk as a leader for the seventh time in a row, placing it at the top of the ranking for "Ability to Execute."

Splunk's ability to search data at high speed against cyberattacks and system abuse has been proven, and Merpay is also using it to execute fraud detection rules.

Due to the new virus, remote work is increasing. I think Splunk will be useful as a "zero trust" monitoring and auditing SIEM when using external systems. Please feel free to contact us.
See you soon! Happy Splunking!!
