Creednz was created at the intersection of finance & cyber security. By leveraging internal financial data sets enriched with externally curated intelligence, Creednz enables finance teams to make informed payment decisions in real-time. Treasury, Accounts Payable and Vendor Management teams operate in silos without access to complete transaction data during payment runs. As an API-first company, data from your ERPs, TMS, Vendor Management, and Accounts Payable becomes accessible and actionable in real-time.

Every security team has a backlog of known issues: dormant accounts that should be disabled, expired certificates, employees with access they no longer need, overexposed data. Some of these are flagged by existing tools. Many are buried, and visible only when you connect context across systems that dont normally talk to each other. Either way, the team knows the types of problems are out there. What they cant do is find all of them, find the capacity to act on them, figure out who owns each one, understand what breaks if they change it, and actually fix it across different systems and different teams at the pace the backlog demands. Surf does all of that. We connect to your identity, cloud, HR, IT, data and security systems, continuously surface issues that no single tool can see and understand on its own, build a real-time map of who owns what and what depends on what, and then use AI agents to drive each fix to completion – with your team approving every step.
