Pentest
Security Evaluation via Attack Simulation
How does it work?
Pentest (Intrusion Testing) is a specialized service that simulates real cyber attacks to identify technical and logical vulnerabilities in an organization’s systems, applications, networks and devices. More than simple scans, Zerum’s Pentest uses advanced methodologies and offensive human intelligence to assess the company’s real level of exposure, enabling proactive corrections before flaws are exploited by attackers.

simulated real exposure with depth
Zerum’s Pentest goes beyond automated scans: it simulates real attacks with human offensive intelligence. The assessment is tailor-made, taking into account the context of your organization and respecting controlled intrusion levels.

customized attacks on your environment
Each scenario is adjusted to the business’s risk profile. Web applications, APIs, internal networks, the cloud, mobile devices and other vectors are tested, always with a focus on identifying critical flaws with real exploitation potential.

certified and experienced specialists
The tests are conducted by a highly qualified team with certifications such as OSCP, CEH and other advanced training. More than ethical hackers, they are offensive analysts with practical experience in high-level simulations.

risk analysis based on real impact
The vulnerabilities found are assessed based on their impact on the business, using recognized frameworks such as CVSS and MITRE ATT&CK. This allows patches to be prioritized based on actual risk, not just technical volume.

practical reports and remediation consultancy
After running the tests, you receive clear, structured reports with evidence, impacts and actionable recommendations. Zerum also supports you in validating the corrections, ensuring that the mitigation was successful.

More
benefits
compliance with standards and audits
Pentest helps meet the security requirements of standards such as LGPD, ISO 27001, PCI-DSS and others. The reports provide technical and executive documentation to prove the effectiveness of defenses during internal or external audits.

strengthening the offensive security culture
As well as identifying flaws, the service acts as an educational element for IT and security teams. It encourages an active defense mentality and prepares the team to react better to real threats.

evolving security with continuous reassessment
After the corrections have been made, Zerum carries out new tests to validate the effectiveness of the actions implemented. This guarantees a cycle of continuous improvement in the organization’s security maturity.

Questions and answers
Vulnerability analysis is an automated scan to identify known flaws, while Pentest goes further, actively exploiting these flaws and simulating real attacks to understand their impact and the possibilities of effective intrusion. Pentest provides a more accurate view of the real risk, including logical and technical flaws.
The Pentest is conducted in strict compliance with the scope and intrusion limits agreed with the client, in order to minimize any operational impact. In critical cases, tests are carried out in controlled environments or outside business hours to avoid interruptions.
The main types of Pentest are:
White Box Testing: The professional has complete access to the environment’s information, such as source code, architectures, credentials and documentation. This allows for an in-depth and detailed analysis, focusing on internal technical and logical vulnerabilities.
Black Box: The professional has no prior information about the environment and acts as an external attacker, trying to discover flaws only from public information and reconnaissance techniques. It assesses the exposed surface and the ability to defend against external attacks.
Grey Box (Grey Box Test): Combines elements of the previous two. The professional receives limited information, such as some credentials or data from the environment, simulating an attacker with partial access, such as a malicious employee or an attacker who has already compromised part of the network.
Yes. After delivering the reports, the Zerum team offers consulting sessions to validate the corrections applied and can carry out reassessments to ensure that the vulnerabilities have been effectively mitigated.
Yes, many clients opt for a combined approach, starting with a Pentest Black Box to map external risks, followed by a White Box for detailed internal analysis, or even carrying out a Grey Box to focus on specific internal threats. This combination offers a more complete and robust view of the organization’s security.
