You will work closely with product managers and legal/privacy partners to ensure incident response standards like NIST and SANS are woven into our lifecycle. You will also produce actionable intelligence by filtering and correlating data from indicators of compromise (IOCs) using platforms like Splunk and CrowdStrike. The secure systems and practices you establish will have a real and lasting impact on upholding the integrity of the data entrusted to HubSpot. By evaluating customer impact on threats and maintaining relationships with industry contacts for intelligence sharing, you will directly contribute to a secure experience for every customer—enabling them to focus on running and growing their business with confidence.
