Impart Security, a cybersecurity company pioneering AI-powered autonomous application protection, has raised $12m in a Series A funding round.
The investment was led by Madrona Ventures, with participation from CRV and 8-Bit Capital. As part of the deal, Madrona managing director Karan Mehandru has joined Impart’s board.
The company has developed a platform designed to revolutionise application detection and response by automating security engineering in production environments. By leveraging advanced AI and WebAssembly (WASM) technology, the system enables enterprises to defend applications in real time without human intervention.
Impart plans to use the funding to drive expansion into critical enterprise sectors including financial services, healthcare, and infrastructure. The company also aims to deepen its go-to-market strategy through strategic partnerships with cloud providers and channel partners, further embedding its security platform into enterprise deployment pipelines.
The platform is already being used by major global enterprises, including a leading financial institution and a major entertainment company. Impart’s technology stands out by enabling security teams to deploy AI agents that act autonomously in production settings, allowing for faster and more secure responses to evolving cyber threats.
These AI agents include specialised roles such as traffic inspectors, detection engineers, and rule engineers. Together, they work as a digital team, identifying anomalies, generating tailored security rules, and enforcing them across environments—all with minimal disruption to operations. During a recent attack affecting multiple clients, Impart’s system detected the threat, created a custom rule set, and deployed protections in minutes—something that typically takes human teams days.
Impart Security CEO Jonathan DiVincenzo said, “This isn’t just about better security tools—we’re fundamentally changing how enterprises engineer application protection. 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 platform’s performance has already shown results, with over 2,400 security rules deployed across customer environments. Deployment times have dropped from 18 days to just 45 minutes, all while maintaining 99.97% uptime.
Crossbeam CISO Chris Castaldo said, “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. Impart is the first platform our team trusts to make autonomous production changes.”
Karan Mehandru, managing director at Madrona, added, “We evaluated dozens of AI security companies, but Impart was the only one that stood out because of its breadth, depth, and usability.”
ThreatSpike, a cyber company specialising in unified security platforms, has recently raised $14m in Series A funding to support its global growth and accelerate innovation.
The round was led by Expedition Growth Capital. As part of the deal, Will Sheldon, partner at Expedition, and Emily Orton, co-founder of Darktrace, have joined the company’s board of directors.
Founded in 2011 by Adam and Kate Blake, ThreatSpike provides end-to-end cybersecurity solutions designed to eliminate the complexity and costs associated with fragmented legacy tools. The platform combines managed detection and response services, as well as continuous penetration testing, to offer businesses complete visibility and protection.
