He then spent 18 years at Microsoft in a series of security platform, cloud, product and engineering leadership roles.
From Microsoft he moved to Google, where he served as a Director and built the Google Cloud Security Engineering organization over three years, working within Google's Security and Privacy organization on public cloud security engineering.
Cross next joined Oracle, where he spent six and a half years as Chief Information Security Officer for the Oracle SaaS Cloud Security organization, holding the title of Senior Vice President.
Atlassian appointed Cross as its Chief Information Security Officer after his time at Oracle, and the company's announcement noted his earlier security leadership roles at Google and Microsoft.
He is also a Venture Partner with Rain Capital VC.

Security communications at Atlassian
As Atlassian's CISO, Cross has used the company's community forum to announce product security features directly to customers. In July 2025 he introduced malware scanning for file uploads across Jira, Confluence and Trello, explaining that the feature scans every new attachment using a combination of in-house and third-party detection tools and flags malicious files with a warning before download, with findings available to administrators through the audit log.
David Cross wrote, "In direct response to your valuable feedback, my team has successfully deployed our new malware scanning solution."
In June 2026, Cross announced the second edition of Atlassian's Rovo Security & Trust White Paper, describing it as a document built with security, privacy and product experts to help customers adopt Rovo AI features while addressing AI-specific security, privacy and compliance concerns, available through Atlassian's Trust Portal.
