Internal pentest for business security

Internal penetration testing is the search for vulnerabilities in a corporate network through safe modeling of attacks from the inside. The service allows you to assess resilience to insider threats and strengthen protection.

The test covers internal services, servers, databases, accounts, and access management systems.

  • Environment analysis
    We identify key test objects, take infrastructure specifics into account, and select optimal testing scenarios.
  • Insider attack simulation
    We simulate hacker actions to identify vulnerabilities and assess the company’s resilience to insider threats and hidden risks.
  • Reporting and recommendations
    We provide a structured report with a technical section, conclusions for management, and advice on strengthening cybersecurity.

Features of cybersecurity testing
What an internal pentest checks

Internal penetration testing covers key objects of corporate infrastructure, takes into account specifics and required depth of testing, and does not affect business processes or resource stability.

The test is relevant for companies of any field and scale, helping to identify hidden threats that attackers may exploit after gaining access to the infrastructure from the inside.

  • Access and authentication testing: we test the reliability of passwords, accounts, access policies, and multi-factor authentication.
  • Analysis of internal services and network: we check segmentation, server and database configurations, and the security of internal APIs and services.
  • Infrastructure resilience assessment: we identify possibilities for privilege escalation, lateral movement across the network, and compromise of critical systems.

What our clients get
Advantages of internal pentest

Penetration testing shows what an attacker can do once they gain access to the corporate network. Simulating hacker actions helps reveal hidden risks, assess the level of protection against insider attacks, and strengthen the security of critical systems.

By ordering an internal pentest, you will get:

  1. A real security picture – we will assess the objective state of your cybersecurity.

  2. Prioritized recommendations – we will provide clear steps to eliminate vulnerabilities.

  3. Improved digital protection – after implementing our recommendations.

  4. Free retest – after eliminating risks, we will recheck the system’s security.

  5. Strengthened reputation – the pentest will confirm the company’s serious approach to security.

  6. Compliance with standards - our report will help in preparation for audits and certifications.
Cybersecurity check results
Internal pentest report
After completing penetration testing, we provide a detailed report describing identified vulnerabilities, risk levels, and recommendations for their elimination. The document contains technical details for IT specialists and a concise summary for management.

How we work on a project
Datami’s approach to internal pentest

We combine international standards and our own experience to ensure the most accurate security testing results.

The testing approach is chosen individually for each project, taking into account the specifics of the client’s infrastructure and business processes.

Black-box
Different scenarios

We apply white-, grey-, and black-box approaches depending on client tasks and access levels.

Gray-box
Combination of methods
Automated scanning for quick coverage and manual tests for detecting complex threats.
White-box
International standards

We follow OWASP, PTES, OSSTMM, NIST for accuracy and transparency of the obtained results.

Security issues inside the network
Vulnerabilities detected by internal pentest
01.
Lack of network segmentation
Users gain direct access to servers, databases, or critical services without isolation.
example_1
02.
Vulnerable applications
Legacy systems and web applications without updates and proper testing contain critical flaws.
example_2
03.
Excessive access rights
Employees have access to resources irrelevant to their role, for example, financial data.
example_3
04.
Active Directory vulnerabilities
Errors in AD open the way to privilege escalation, Kerberoasting, poorly secured GPOs, or delegations.
example_4
05.
Weak credentials
Passwords are simple or outdated, standard accounts are used, and there is no multi-factor authentication.
example_5
06.
Lack of event monitoring
Attacks go unnoticed due to weak event logging or the absence of effective EDR/SIEM.
example_6
07.
Lateral movement
An attacker can move across the network between machines, approaching critical systems.
example_7
08.
Dangerous services
Open databases, interfaces, or APIs without authorization or access control.
example_8
09.
Former employee accounts
Inactive or compromised accounts remain available for login.

Frequently asked questions

Yes, it is relevant for companies of any scale. Attackers often choose the least protected targets, so even small companies should check their security.

We recommend conducting it at least once a year, as well as after significant infrastructure changes, implementation of new systems, or after security incidents.

The duration depends on the company’s scale and the number of objects to be tested. On average, the test takes from several days to two weeks.

Penetration testing simulates attacker actions and shows real risks. An audit checks whether policies and processes comply with standards requirements.

Yes. The test is carried out in controlled conditions, does not affect business processes, and does not interfere with service operation.

The price depends on the number of objects, the complexity of the infrastructure, and the depth of testing.

No. We conduct testing without stopping business processes — all actions are agreed upon in advance and carried out without risk to system stability.
