CTI-Ops is a Cyber Threat Hunting Service offered by the Analyst team from CTI Labs @ Marlabs to help customers detect and identify timely, relevant, context-rich and accurate cyber threats to answer generic and specific security concerns. CTI-Ops service includes searching iteratively through collected data or external data sources to detect advanced threats that evade traditional security solutions. CTI-Ops is a Human driven search for one or more segments of a cyber-attack conducted by an adversary, using tools, information and investigative techniques. It is not just waiting for an alert to be fired from a piece of technology. It also co-relates attacks and alerts to gain targeted intelligence.
