WEB APPLICATION PENETRATION TEST

LEAN SECURITY uses the comprehensive penetration testing methodology to assess the security of the web application and identify the security risks. The methodology is based on OWASP and NIST recommendation. Various tools and the techniques are used to discover the vulnerabilities within the target web application. Each application is manually audited by an experienced penetration tester with the assistance of penetration testing tools such as the Burp Suite. The audit attempted to identify not just common classes of security vulnerabilities, but also vulnerabilities specific to the application itself.

Also known as Source Code Analysis, Static Code Analysis is usually done as part of white-box testing or Code Review. It’s performed at the Security Development Lifecycle’s implementation phase. Static Code Analysis usually pertains to the running of SCA tools that try to underline possible vulnerabilities in non-running or static source code by using methods like Data Flow Analysis and Taint Analysis. Ideally, security flaws would be found by such tools with a high level of confidence that what’s detected is really an error, but this not enough for many forms of application security flaws. Such tools, thus, often function as aids for analysts to help them determine security relevant parts of code so that they can detect errors more effectively.

MOBILE APPLICATION PENETRATION TEST

Our comprehensive demand to this mobile application testing is to see and determine the entire technology pile including network, server and client. This comprehensive and holistic approach is utilized so that unwanted vulnerabilities detected in the component can be utilized while testing the server. Before the testing begins, we facilitate full installation of application and carry out inclusive walk-through utilizing several functions available. We identify ways on how components work altogether and leverage the flow as assessment takes place continuously. 

Your organisation's internet-facing perimeter is the frontline in its defence against cyber threats. It is the collection of servers, services, and applications that are publicly visible and accessible to anyone in the world—including malicious attackers. This external infrastructure is under constant, automated scanning and targeted attacks, 24/7.

A single misconfigured firewall, an unpatched server, or an exposed administrative login can provide an attacker with the initial foothold they need to breach your entire network. Our External Infrastructure Penetration Test simulates the actions of a real-world attacker to identify and validate these critical vulnerabilities before they are exploited.

API Security Assessment

APIs (Application Programming Interfaces) are the engine of modern digital business. They power your mobile apps, connect your cloud services, and handle the critical data exchange between your business and your customers. Unlike traditional websites, APIs are designed for direct, programmatic interaction, making them a prime target for sophisticated attackers.

Because APIs expose application logic and direct data access, they are susceptible to unique and severe vulnerabilities that standard security scans often miss. A single flaw in an API can lead to a catastrophic data breach. Our specialised API Security Assessment focuses on finding and fixing these critical vulnerabilities—from broken authorisation flaws to complex injection attacks—ensuring the backbone of your business is secure.

Threat Modelling Service

Are you building security into your new applications from day one, or treating it as an afterthought? How do you identify critical security flaws in the design of a new feature, before a single line of code is even written? Do you know the true cost of fixing a vulnerability found in production versus one caught on the whiteboard?

Lean Security’s Threat Modelling service shifts your organisation's security from reactive to proactive. This isn't a standard penetration test on finished code; it is a collaborative analysis of your application's design. We help your team identify architectural flaws and potential attack paths before they become expensive and time-consuming problems to fix. This is about making a strategic investment in secure-by-design principles to build fundamentally resilient applications.
