Interloper
A cybersecurity testing tool built for NGOs and local CSOs. It helps teams identify vulnerabilities in web applications and APIs and understand how to fix them—without needing specialist security expertise.

Challenge
NGOs and local CSOs manage sensitive and operational data but often lack access to affordable cybersecurity expertise. Existing testing tools can be expensive, overly technical, or difficult to deploy, leaving smaller organisations unable to identify and address vulnerabilities.
Solution
Interloper provides guided workflows for testing web applications and APIs, understanding potential security issues and acting on the findings. It combines automated security checks with plain-language results and practical remediation guidance designed for NGO teams.
Key features
Cybersecurity testing for NGO teams
Guided workflows allow NGO IT, product, and development teams to run scans without specialist penetration-testing expertise.
Automated web and API scanning
Check for common vulnerabilities, including injection flaws, broken access controls, insecure authentication, missing security headers, and other configuration weaknesses.
Actionable reports and guidance
Prioritise findings by severity and explain the issue, evidence, potential impact, and recommended next steps. Results can be exported in PDF and JSON formats.
Flexible deployment
Designed to support local execution and self-hosted web deployment, helping organisations keep sensitive vulnerability data within their own infrastructure.
