We also conducted threat hunting analysis to look for suspicious, malicious activity.


Based on the current evidence, we do not believe that any Optiv information or client information, related to services provided by Optiv, was impacted by this event. We will continue to monitor the situation and deploy additional countermeasures, controls and patches when they become available. If Optiv becomes aware of any incidents related to CVE-2021-44228 which affect our clients or their data, we will notify impacted customers without delay.


Optiv delivers strategic and technical expertise to more than 7,000 organizations across every major industry.  We take into account the diverse range of security strategy, planning, risk management, threat modeling, monitoring, operations, governance and controls to ensure that our environment remains secured and protected appropriately. Specifically, we receive regular threat feeds from multiple credible sources and a dedicated team performs due diligence to review, analyze and monitor relevant indicators of compromise (IOCs) on an ongoing basis. Additionally, we perform internal and external security assessments regularly to ensure that gaps, if any, are remediated in a timely manner. Lastly, we work with an independent third party annually to obtain a comprehensive due diligence packet that includes a SOC2 Type II attestation as well as assessments such as the SIG questionnaire and a PCI-DSS SAQ-D, amongst others.


Optiv is committed to securing our environment and protecting our clients. For more information about this vulnerability, please see Optiv’s Global Threat Intelligence Center (GTIC) Advisory and list of Log4j vulnerable vendors.
