What is pentesting
When we are talking about the definition of pentesting we refer to the Spanish term ” penetration test or examination ” to refer to the procedure of attacking a computer system to detect possible vulnerabilities or cybersecurity failures.
In this way, we are talking about a ‘hack’ carried out by cybersecurity experts and that, unlike those we know from the news, is completely legal and has the backing of those responsible for the company or organization to undertake.
Is pentesting the same as a security audit? Although both processes are linked to the company’s cybersecurity strategy, they do not refer to the same thing. With the security audit we detect vulnerabilities in our cybersecurity, while pentesting goes one step further and exploits those vulnerabilities to check what effects a cyber attack would have on our system.
The importance of pentesting lies in testing, in a controlled way, the same tools that cybercriminals would use in a computer attack against the company. Dig deeper into this topic with this interview to cybersecurity expert David Santos
The importance of pentesting in a security strategy
Why is pentesting important in a security strategy in companies? The first reason is obvious: because we test the reliability of the organization’s cybersecurity measures and tools.
In the same way, this test offers us reliable results when faced with a ‘real’ cyberattack that details the response of our computer security systems, as well as the level of updating of the tools available to the organization.
In this same plane, thanks to a penetration test we can check the real effects of a cyberattack on our computer system and measure what reaction capacity the company would have if it occurred . Do you know these signals to detect a cyberattack in your company?
All this in a context marked by constant security threats and increasingly critical attacks on corporate security systems on a global scale. In 2018, our country received more than 38,000 attacks of which almost one hundred were “critical”.

Phases and types of pentesting
What are the pentesting modalities that are available to companies and what phases must be completed to obtain a good diagnosis of the organization’s cybersecurity? About the phases of a pentesting process, it consists of at least these points:
- Collection of information on all computer security systems, programs, protocols, permissions … In the same way, technical analysis with tools such as Nmap (port scanning), FOCA (metadata analysis) or PassiveRecon (for websites), among others.
- Search for vulnerabilities from the information collected in the first step of pentesting.
- Exploitation of vulnerabilities and subsequent analysis of the information and the effects it has had on the security system and equipment, as well as data on response time.
- Preparation of reports specifying which vulnerabilities have been found and how they have been exploited. Analysis of the state of the security systems and programs, recommendations and measures to solve the detected problems.
In the same way, depending on the needs of the company, different types of pentesting analysis can be established:
- White box pentesting : Collects all the information about the system, the application or the architecture. According to experts, it is the most complete pentesting.
- Black box pentesting : It is almost like a blind test and the closest to follow the characteristics of an external attack. Their performance is the most similar to that of cybercriminals.
- Gray box pentesting : this modality of penetration examination would be a combination of the previous two. The information that has been collected is analyzed and, based on the data, the vulnerabilities in the system are exploited. This is the most recommended by experts for a complete analysis of the company’s cybersecurity.
