| Nokod Security | Nokod delivers an application security platform for low-code / no-code custom applications and Robotic Process Automation (RPA). As part of their digital transformation initiatives, most large organizations have adopted low-code /no-code and RPA platforms (e.g. Microsoft PowerApps, Outsystems, UiPath, ServiceNow, Salesforce, etc.),without any insight as to whether these newly developed applications introduced vulnerabilities, malicious activity or compliance violations. This new attack surface is uncovered by the current application security stack. The Nokod platform allows organizations to govern their low-code / no-code custom applications and automations, and manage their cyber security and compliance risk stemming from these applications by streamlining security into the application’s lifecycle. The platform discovers the organization’s low-code / no-code applications, reveals security issues, detects vulnerabilities, and offers auto remediation. With Nokod, companies can now be confident that their digital transformation programs scale in a secure and compliant manner. The company is co-founded by Yair Finzi, CEO (previously co-founder of SecuredTouch, acquired by Ping Identity) and Amichai Shulman, CTO (previously co-founder of Imperva). | $8M | Seed | Jun 29, 2023 |  |
