AI Pentesting Platform

HQ

Tel Aviv, Israel

VC Partners

Novee is the first continuous offensive AI penetration testing platform engineered to mimic a real attacker – autonomously, and at scale. It combines the continuous coverage of scanners with the depth of real penetration testing – chaining vulnerabilities, reasoning about business logic, and validating only what's actually exploitable.

It tests across web, mobile, desktop, and LLM-powered applications, identifying risk the moment it's introduced. Unlike other tools, Novee doesn't stop at detection. Every finding is proven, prioritized by business impact, and paired with tailored remediation guidance and automatic retesting to verify the fix.

Cloud Security Control Plane

HQ

Seattle, USA

VC Partners

Cloud security has long prioritized detection. It has never had an architecture layer that makes insecure states structurally impossible. As AI-augmented attackers operate at machine speed and every engineering team adopts AI services that existing controls were never designed to govern, that gap has become one of the most consequential and under addressed exposures in cloud security today.

Native is the Cloud Security Control Plane, using the built-in security controls across AWS, Azure, Google Cloud, and OCI: it is the system enterprises use to enforce secure-by-design architecture at scale, before adversaries exploit what was never enforced at the architectural level. It translates security outcomes into consistent, predictably enforced provider-native guardrails across cloud providers, simulates real-world impact before deployment, and keeps enforcement current as providers and the organization evolve.

AI-Native Identity Security

HQ

As enterprise environments grow more complex, identity governance has outgrown legacy tools. The bottleneck has shifted from having the data to being able to act on it. Opti turns identity governance from a periodic, manual process into a continuous operation across all access types, including human, non-human, and agentic identities. Purpose-built AI models power risk remediation, access administration, and automated user access reviews. Teams define governance policies in plain English, and Opti translates them into live actionable logic that adapts as the environment changes. It deploys in hours, not months, across cloud and on-prem environments. Opti is the exclusive IAM security partner for AWS Security Hub Extended and has been named by Gartner in the emerging identity governance landscape.

Autonomous Security is a security layer purpose-built for the agentic era. While traditional EDRs monitor binaries, we monitor AI intent where agents interact with your system. Our platform provides real-time oversight to intercept prompt injections and neutralize malicious or vulnerable MCP servers, skills, and plugins before they compromise the endpoint and run different guardrails on top of everything.

With native agents protecting thousands of Mac, Windows, and Linux machines, we offer proven scale combined with a proprietary secure cloud for sandboxed MCP execution. By auditing the source code, dependencies, and configurations of every non-binary software, we close the visibility gap that leaves traditional security blind to semantic threats. Furthermore, our integrated token vault hyper-secures all tokens and secrets to prevent token theft incidents.
