Impart Security Raises $12M Series A for Production-Trusted AI Security Platform

SAN FRANCISCO--(BUSINESS WIRE)--Impart Security today announced the general availability of the industry's first Application Detection and Response Engineering Platform, which security teams trust to build autonomous workflows for production environments. The launch comes alongside a $12 million Series A funding round led by Madrona Ventures, with participation from CRV and 8-Bit Capital. As a result of the financing, Madrona Managing Director Karan Mehandru has joined the board.
Impart's breakthrough platform already protects major enterprises, including a major financial services firm and a global entertainment conglomerate, by defending against threats in real-time without requiring human oversight, achieving what security experts called impossible until now.
"This isn't just about better security tools—we're fundamentally changing how enterprises engineer application protection," said Jonathan DiVincenzo, CEO of Impart Security. "When AI can be trusted to manage production changes without oversight, it transforms from an assistant into an autonomous operator. That's the difference between traditional approaches to application security and genuine business transformation."
The Fundamental Problem – Enterprise security teams have long been trapped in an impossible tradeoff: allowing attacks through or risking production outages. Traditional security solutions force teams to choose between robust protection and system stability, leading most organizations to operate with minimal security settings rather than risk disrupting critical business operations. This defensive posture leaves applications vulnerable to the very threats security teams are tasked to prevent.
The Breakthrough: Programmable WASM Rules – While fully autonomous application security has been promised for years, trust and safety concerns have prevented real-world deployment. Impart's platform leverages WebAssembly isolation technology to create secure sandbox environments where security teams, assisted by AI agents, can design, develop, and test security rules against live traffic patterns without risk of lateral movement or production impact. Not only does WASM provide secure isolation, but it's also highly performant with ahead-of-time compilation and portable across platforms. This foundational innovation unlocks unparalleled safety and agility in Impart's platform, allowing security teams to rapidly iterate and deploy security controls in production environments with unprecedented speed and confidence.
Early results demonstrate the impact: Impart's AI has successfully deployed over 2,400 security rules across customer environments, reducing average deployment time from 18 days to 45 minutes while maintaining 99.97% uptime—better than most human-managed security systems.
"We've evaluated every AI native security platform on the market, but they all had the same fatal flaw: they still required human review for production changes," said Chris Castaldo, CISO at Crossbeam. "Impart is the first platform our team trusts to make autonomous production changes. In three months, it's caught dozens of attack patterns our previous tools missed entirely while never causing a single service disruption."
Autonomous Security Engineering at Scale – Impart's platform deploys a growing number of specialized AI agents that function as a coordinated team of application security engineers, including:
Traffic Inspector – Continuously inspects traffic flows to identify behavioral patterns and baselines
Detection Engineer – Spots anomalies and potential threats as they emerge in real-time
Security Architect – Develops and tests security rules within isolated sandbox environments
Rule Engineer – Adapts defenses based on new attack vectors and threat intelligence
The technology recently proved its value during a sophisticated application attack targeting multiple Impart customers simultaneously. While traditional security teams would have required days to analyze the attack pattern and deploy a virtual patch, Impart's AI identified the threat signature, generated custom detection rules, and deployed protection across all affected environments within minutes of the initial attack.
Investor Validation After Rigorous Technical Diligence – "We evaluated dozens of AI security companies, but Impart was the only one that stood out because of its breadth, depth, and usability," said Karan Mehandru, Managing Director at Madrona. "Every enterprise we speak with desperately wants to leverage the incredible benefits of AI and unlock innovation, yet none of that is possible without a comprehensive security platform that is proactive, fully autonomous, AI-native, and ultimately removes the burden from security teams who are drowning in point tools. The feedback we received from multiple CISOs we spoke with was unambiguous and overwhelmingly positive about Impart's differentiation as a product and their leadership team, led by Jonathan DiVincenzo. It is clear to us that Impart has solved the last mile problem that had previously limited AI from being truly transformative in enterprise and from deploying applications into production."
Industry Transformation Ahead – The Series A funding will accelerate Impart's expansion into three key enterprise segments: financial services, healthcare, and infrastructure providers—industries where security speed directly impacts business operations. The company is also launching partnerships with major cloud platforms and channel partners to integrate autonomous security capabilities directly into enterprise deployment pipelines.
"We're thrilled to partner with Karan and the team at Madrona," said DiVincenzo. "As we enter our next phase of growth, Karan's go-to-market expertise will be invaluable as we expand our sales and marketing efforts while continuing to strengthen the platform that has resonated so strongly with the market."
