Why do you need a penetration test?

To effectively protect yourself against hacker attacks, penetration tests can give a clear picture of the system’s security situation. We give six reasons why organizations need regular pentests:

Protection against Loss
of reputation

A penetration test reveals weak points and checks how vulnerable a system is. Together with the customer, security measures are then taken to protect data in the event of an actual attack by malicious hackers.

Protection of data and
intellectual property

A penetration test, conducted by an independent third party, reduces the risk of an attack and thus protects against a possible loss of reputation.

Fulfilling legal obligations

Sensitive data require special protection. In the context of IT governance, numerous legal requirements require the proper operation of an information security management system.

Recommendations for safeguarding measures

Anyone who has a penetration test carried out receives a detailed report that enables your IT management team to understand the risks of the current situation and gives IT specialists recommendations for specific security measures.

Quality management

Many companies set up internal QM systems to ensure the quality of services and products. In addition to code reviews for software products, penetration testing can be used to check and measure the reliability of information technology.

Certifications and Compliance

For certain industries and processes, it is necessary to meet standards. For example, companies that conduct credit card transactions must comply with the PCI data security standard. To achieve compliance, it is necessary to check systems by an independent third party. A security level proven by a penetration test is a clear competitive advantage here.

Types of penetration testing

Types and models of penetration testing that we offer

Qualified experts from ESKA can check and test vulnerabilities in all types in different infrastructure directions. There are several types of penetration testing:

How it works

How our white hackers work 

A penetration test is usually roughly divided into six phases:

Fill 1 (1).png

Scanning phase

Fill 1 (2).png


Research of all artifacts and resources related to the customer (domain names, IPs, 3d party resources) including from Darknet. Сoordination of test objectives, scope, test methods, and devices.

At this stage, we are looking for open paths to computers and resources. The system is "touched" for the first time. Here we are attempting to obtain information from different sources.

This phase often runs at the same time as stage 2. Its goal is to get real, useful information through the security check.  At this stage, we search for suitable exploits, conduct detailed network analysis, hash cracking, and coordinate further attacks.

Evaluation and

Post-implementation review

Here we conduct the verification tests (exploitation of vulnerabilities, circumvention of security measures and active intrusion, man-in-the-middle attacks, post-exploitation, etc.)
Then we repeat levels 2 to 4.

To be able to realistically assess the actual security situation, a detailed report is necessary. During the final analysis, we evaluate and document the results, make the summary and presentation, and listing of weak points, and give recommendations for countermeasures.

We will provide specific recommendations for your further actions required and support you in their implementation if needed. We will check all corrections and improvements to make sure that our recommendations work in right way.

What we done

Case Studies in Industries

Each month, we usefully close our projects. Here is the list of our recent ones.

Penetration test for the international insurance company

The main goal of this penetration test was an examination of the client's infrastructure through the third party for possible issues that could affect the security of the applications, infrastructure and privacy of its users. The assessment also checks and evaluates security configurations that ensure the confidentiality, integrity, and availability of the client's company sensitive data and other resources.

Platform that provides people management solution for the SMB market

Our customer, a young startup with a strong customer case, asked us to conduct testing and provide an independent report on their vulnerability assessment. The web application was evaluated, and we provided it with a detailed report on its security status.
In the future, that report helped them confirm their level of security and raised the level of trust of their future customers.

The Logistics company wanted to check mobile application before launch

A dominant Logistic provider finished their new mobile application, developed by 3rd party contractor, and requested to check the security level of this mobile application.
As a result, our customers get the confirmation of the level of protection of the mobile application, recommendations for improving the level of security, and contractors' qualifications.

A financial company decided to improve its security

An international investment services company is constantly working with customers' crucial data and must ensure their security and safety.
In the future, the company was able to significantly increase the level of security and ensure the security of its customers.
