This is our comprehensive "black-box" assessment, designed for the majority of business-critical web applications. It is ideal for testing applications with multiple user roles (e.g., users, managers, administrators) and complex business logic. We simulate the actions of a real-world attacker to identify vulnerabilities that could compromise your application and its data.

Who is this for? Businesses needing to satisfy regulatory obligations (PCI DSS, ISO 27001), meet tender or customer security requirements, and proactively secure their primary web platforms.

Methodology: A thorough, manual penetration test based on OWASP and NIST standards, conducted by a senior certified penetration tester.

Deliverable: A comprehensive penetration testing report detailing all findings with a clear remediation plan, and a formal Certificate of Penetration Testing to share with your clients and stakeholders.

This is our premium continuous security assessment, designed to integrate natively into modern DevSecOps workflows. Traditional point-in-time annual penetration tests are obsolete the moment a new feature is deployed, while automated scanners produce massive "alert fatigue" and false positives that engineers hate.

Our Event-Driven PTaaS solves this by continuously monitoring your CI/CD pipeline and cloud infrastructure for changes (the "deltas"). We use AI to filter out the noise, while our senior human penetration testers manually exploit and verify the high-risk changes in real-time.

Who is this for? CTOs, VPs of Engineering, and CISOs at B2B SaaS companies, FinTechs, HealthTechs, and cloud-native scale-ups needing to satisfy continuous compliance requirements (SOC 2, PCI DSS, ISO 27001) without slowing down their engineering teams.

Methodology: Continuous Delta Testing. We perform targeted, manual penetration testing sprints exclusively on newly deployed code and infrastructure, aligned with OWASP and NIST standards.

This is our all-in-one "glass-box" security assessment, combining elite services into a single, unified engagement. This package provides the highest level of assurance for your most critical applications. It combines a "black-box" Application Penetration Test, a "white-box" Source Code Review, and a "white-box" Cloud Security Review (AWS, Azure, or GCP).

This holistic approach identifies vulnerabilities from the outside-in (like an attacker) and the inside-out (like a privileged insider), from the first line of code to the cloud infrastructure it runs on.

Who is this for? Organisations with business-critical, cloud-native applications processing highly sensitive data that need to satisfy the highest level of regulatory, customer, and board-level security scrutiny.

APIs are the nervous system of modern digital business, connecting your data, mobile apps, and partners. However, they are also the #1 target for sophisticated cyber attacks. At Lean Security, we move beyond basic scanning to provide an expert-led penetration test for your API applications.

We test modern REST, GraphQL, and legacy SOAP services to identify critical vulnerabilities that standard automated tests miss.

Methodology: A hybrid approach combining automated test efficiency with deep-dive manual testing based on the OWASP API Security Top 10.

Designed for business-critical desktop applications (Windows, macOS) and mobile applications (iOS, Android) that process or handle sensitive customer, financial, or healthcare data. It provides the assurance that this data is protected both on the user's device and during transit to your servers.

Our assessment provides a comprehensive 'grey-box' review. We analyse the installed application to find client-side vulnerabilities like insecure local data storage, weak encryption, and potential for reverse engineering. We then rigorously test the backend APIs to ensure that all data is securely transmitted, authenticated, and authorised.

Methodology: Based on the OWASP Mobile Application Security Verification Standard (MASVS) and recommendations from NIST.
