Impart Security’s $12M Raise Tackles ‘Last Mile’ of Application Protection

In enterprise security, there’s an awkward silence that inevitably follows one question: “Can we set it to auto-block in production?”

Jonathan DiVincenzo, CEO and co-founder of Impart Security, has seen that silence play out many times. Now, his company, courtesy of $12 million, from a Series A led by Madrona Ventures, that they’ve finally solved what he calls “the last mile problem in application security.”

For years, security teams have been stuck choosing between two evils: leaving applications vulnerable to attack, or risking system instability by deploying untrusted automated tools in production. The result is often a defensive stance: monitor-only modes and watered-down protections that offer limited real-world security. “Most security teams I speak with enable a few generic rules but can't implement anything beyond that due to the high cost of tuning, maintenance, and ongoing management,” DiVincenzo said on the company’s launch blog.

Impart Security’s approach looks to break from this mold. The company offers what it calls an Application Detection and Response (ADR) Engineering Platform, a programmable system that allows users to safely design, test, and deploy AI-driven security controls tailored to their applications. Unlike legacy “black box” tools that generate endless alerts with little context, Impart gives security teams the means to actively shape their defenses in real-time production environments.
