Response automation is a major part of the pitch, so pre-approved SOAR actions and rollback rules should be documented before go-live.. DFIR and payment forensic services are adjacent SISA services, so buyers should confirm what investigation and response work is included in MDR. | Public pages do not publish response SLAs or named default response actions.. The public MDR page says mitigation is immediate where possible, but does not specify what Tesorion can do without customer approval..
