Penetration Testing

Modern-day hacking goes far beyond the standard cybersecurity measures and bypass even regulations and security requirements. Organisations are put on the line and they must ensure their systems, clients, employees, and processes are protected from DDoS attacks, phishing, malware, ransomware, and even for the worse – the threats of piracy violation and terrorism. And if the business fails to do that? Everything can be discredited – their brand, reputation, and value. This will harm the commercial operations and of course – the revenue streams.

There are a lot of solutions out there that are marketed to businesses as cures for all cybersecurity problems. Looking at the sector, we can say that penetration testing is the best prevention if you want to ensure your cybersecurity with realistic, practical and popular tools. It is proven in time and gives concrete results in strengthening cybersecurity defenses.

Penetration Testing (or PenTest) can be also described by the term Ethical hacking

 What it does for an organisation is that it can help the detection of the weak spots in its cyber defenses. After the vulnerable places for attacks are mapped out, a report with recommendations is provided. It describes the measures that need to be taken to improve cybersecurity and ensure no future threats and potential risks of breaches.

We, at WiserSec, have a tailor-made approach when it comes to penetration testing. We approach each client specifically and address the needs they have and the issues they struggle with. This allows us to conduct the PenTesting on shorter notice, which results in better prices for the organisation.

Black-box testing

In this type of testing, the cybersecurity experts will put themselves in the role of any random hacker out there that has taken your system on their radar. However, in this case, there won’t be any internal information available to them. This type of penetration testing targets more common vulnerabilities from the outside of the organisation and tests their defenses.

When black-box testing is carried out, the experts in cybersecurity have to infiltrate your organization and hack your systems.

Grey-box testing

In the scenario of grey-box testing, the experts carrying out the penetration test have limited information about the system that is in place. This type of knowledge mainly involves the average use and the elevated privileges. In that way, the person that carries out the test can target the more important systems. Those that have a higher value for the organisation. And as a registered user he or she will be able to simulate a cyber attack from someone that has long-term access to the network of the company.

White-box testing

As you can imagine here the person doing the testing knows a lot about the systems he or she is attacking. Here the tools that take place can include code analyzers and debuggers having knowledge about vessel and shore sides such as: 

  • Schema;
  • Source code;
  • OS details;
  • IP addresses.

All of this information allows for discovering, and analyzing system-wide vulnerabilities that can be both internal and external. 

Network services testing

As part of the penetration testing, the network services testing targets specifically things like:


  • Individual computers of employees; 
  • Network printers;
  • Routers; 
  • Firewalls.

Wireless network testing

In post-Covid-19 times more and more companies moved to work online and offer flexibility to their employees. However, this has its risks, and here comes wireless network testing. This type of penetration testing focuses on potential rogue access points and weak security algorithms. Part of the process here are things like information leakage, session hijacking, and wireless sniffing.

Web application testing

As the name suggests, this type of penetration testing checks the vulnerability of web applications. The process goes through every aspect of a web application and determines if there is any security risk. In recent years cyber attacks on such types of apps have increased.

In this case, the experts that do the penetration testing will identify cyberattack vectors that can be used to target and affect web applications, hosting infrastructure, and data management of the organisation.

Social engineering testing

Cyberattacks often are the result of a mistake made by someone from the staff of the organisation. This is where social engineering testing comes in. When it is carried out, it focuses on specific things like how employees might react to attacks that can cause a breach like: 

  • phishing email campaigns;
  • spear-phishing emails;
  • over-the-phone attacks (vishing);
  • SMS attacks (smishing). 
  • The good cybersecurity experts will go further and even do physical impersonation and verbal intimidation.

Client-Side testing

Here the focus is on any client-side software and devices and the vulnerabilities they carry. The cybersecurity experts will check for potential breaches that may harm your organisation from external applications you use.

Segmentation testing

Segmentation testing is not so familiar but it is a very important part of penetration testing. It involves the segmentation and the usage of the networks by the organisation. While there are some with lower levels of security, they can still compromise the ones that have high security.
