Web Security Audits Objectives

Web Security Audits Objectives

Web applications maintain one of the main entry points for attackers whose aim is to compromise the security of the organization which can lead to reputation damage.

This exposure to both external and internal agents make the web application a target of constant threats using classic techniques or more modern techniques that are constantly evolving. Implementing regular security audits is a priority to contain these types of threats.

Web Security Audit Benefits

The benefits offered by our web security services include the identification of the following things:

  • Web server configuration and infrastructure vulnerabilities.

  • Application vulnerabilities, verifying all types of injections and advanced techniques on your entry points.

  • Software vulnerability and framework with known weaknesses.

  • Vulnerabilities related to business application logic that cannot be identified by automatic tools.

  • Specific security tests adapted to multiple types of web assets and technologies such as eCom, APIs, management portals, PSD2, CMS,CRM, etc.

Web Security Audit Benefits


Our security audits maximize the detection of real threats that may put the security of your information managed by the web application and its infrastructure at risk. To achieve this objective, we apply an extensive and exhaustive battery of tests that include both recognized and open methodologies (OWASP), as well as specially crafted tests that are designed in a creative way by our expert team. This way, the analyses performed allow us to comprehensively identify weaknesses related to the server infrastructure, whether it be from inadequate programming, specific business logic or simply the absence of good security practices to provide a more in-depth defense.

OWASP Methodology

As a part of the web security testing, Tarlogic makes use of international proven methodologies such as OWASP (Open Web Application Security Project). This applies an open and collaborative methodology that is periodically updated and used as a reference to web application security audits. At Tarlogic, we rely on the OWASP methodology in all our web security audits to analyze and assess risks through more than 90 specific controls.

Specific Tests

Our team of experts have put a considerable amount of effort into understanding the business logic of analyzed web applications. This has allowed us to design specific tests that take into account the possible workflows of the information managed between interrelated web functionalities, and to identify vulnerabilities that would have been impossible to detect using automated tools.

We also carry out tests related to the latest techniques and trends in the fields of web security, including the specific architecture of the analyzed application.

Frequently asked questions about website security audit

What is a website security audit?

Web security audits consist of the identification of vulnerabilities on web assets such as websites of different sizes, from static websites to corporate platforms, intranet, e-commerce, APIs, and any component of the web; also, in the scenarios where it is agreed in the scope, the evaluation of the systems that support the applications, middleware, and backend.

The audit exercises are based on security analysis methodologies, which are internationally used, such as OWASP Security Project, for the evaluation of the security controls, or the usage of numerous tests that allows evaluating whether a web asset complies with the required security measures or if it requires a review by the technical teams, to mitigate possible weaknesses that may affect the security.

As complementary techniques, security scans of a web application are carried out to identify all the public and private resources available and accessible remotely to analyze their behavior towards anomalous data inputs.

All security tests can be performed both anonymously, pretending to be an external user to the organization without access, or authenticated, with one or more valid users in the web application.

The outcome of a web security audit is the list of technical vulnerabilities that pose a threat to the application, the list of the security controls used and whether they have passed, as well as a detailed set of recommendations to be applied at different levels: application level, source code, architecture, configuration, or the infrastructure itself.

How much cost a website security audit?

To understand the cost of a web security audit, it is required to understand the complexity of the web, which fundamentally depends on three variables:

  • Number of resources exposed by the application.
  • The complexity and size of the web, if it is a transactional website that requires users with different roles and privileges.
  • The methodology to follow in the security review: Black box (without any information on the application or the users to simulate an external attack), white box (with more information and with tests authenticated with username and password) or mixed.
  • The need to use a specific analysis methodology (OWASP, WASC, etc.) or specific security controls.

The best approach to assess the effort is to access the web application so that our web security experts can estimate the effort required to fully analyze the application.

Depending on the complexity of the web and the depth of the work to be perfomed, the cost may vary from 3,000€ and 30,000€. The cost as well as the type of exercise will depend on whether the work consists on a one-shot web security audit or if a verification of the corrected vulnerabilities is included, or if the client wishes to have a recurring service with a broader scope.

We advise our clients to choose the best approach for their needs and expectations in order to ensure that the application is secured.

What is the goal of a web security audit?

The objective during a security audit is to identify configuration problems, development problems or problems on the logic of the application that may allow, for example, unauthorized access to information managed by a system or unauthorized actions that are not permitted to a user, such as to impersonate another user or to take control of the web server or the application database.
