Professional Penetration Testing Services
NIST Security Services provides quality pen testing services encompassing web application penetration testing, mobile application penetration testing, and network penetration testing. As a company operating in the USA and the EU, with a strong focus on Germany, we are a trusted partner for companies seeking to protect their web and mobile applications, as well as networks and cloud infrastructures.
Our Offering
Black Box Pentesting
We provide black box pen testing services, when we have no access to the source code or internal design of the system, and rely on public information such as the system’s behavior, inputs, and outputs.
Grey Box Pentesting
We conduct grey box pentests, when we have some knowledge or information about the target system from different sources, such as previous tests, but not complete access to its internal workings.
White Box Pentesting
We conduct white box pentests, when we have complete information about the target system, including its architecture, source code, and access to sensitive data, to allow deeper examination.
Clouds
We assess AWS, Azure, and other cloud computing environments to identify vulnerabilities such as misconfigured access controls, weak authentication mechanisms, and insecure data storage, and provide recommendations for your IT team.
Networks
We assess networks, IT systems, and infrastructure to identify vulnerabilities such as misconfigured access controls, weak authentication mechanisms, unpatched systems, and others, reducing the risk of data breaches or other security incidents.
Why Penetration Testing?
Web and mobile apps, networks, and cloud infrastructures are prime targets for cybercriminals, making security a top priority for organizations handling sensitive user data. A penetration test simulates real-world attacks on your digital assets, exposing potential weaknesses in areas such as data storage, API security, authentication, and session management. By identifying these vulnerabilities proactively, we help you prevent data breaches, protect user information, and maintain regulatory compliance across industries.
Penetration Testing Process
We use a combination of manual and automated methods to simulate real-world attacks on applications, systems, and networks. Typically pen testing projects include the following stages:
- Information Gathering: We collect essential details about your digital assets, such as platform, API endpoints, architecture, and potential risks within connected services.
- Vulnerability Scanning: Using a suite of tools, we scan the target to identify known vulnerabilities.
- Exploitation: We attempt to exploit identified vulnerabilities to determine how an attacker might gain unauthorized access to your infrastructure, app, or sensitive data. This phase focuses on goal-specific risks such as for instance, insecure session management, weak API security, and cryptographic flaws.
- Privilege Escalation: Once initial access is gained, we explore ways to escalate privileges within the app to access more sensitive data or functionalities, demonstrating the potential impact of each vulnerability.
- Maintaining Access: We evaluate ways in which an attacker might retain access to your network or app. This stage highlights persistence methods that attackers could use to stay undetected.
- Reporting: Our reports are thorough and developer-friendly, offering clear technical and business insights into the identified vulnerabilities. Each report includes:
1. A detailed attack narrative that explains how potential attacks could unfold, helping your team understand the risks.
2. Specific remediation recommendations that are practical and actionable.
3. Compliance information to help meet standards such as OWASP, CREST, NIST, and other relevant frameworks in mobile security.
Our Certifications
Deliverables
- Executive Summary: A high-level overview of the pen test results.
- Test Plan: A document outlining the scope, objectives, and approach of the pentest.
- Detailed Technical Report: A comprehensive report documenting all findings and recommendations, including descriptions of vulnerabilities and their impact, proof of concept, and remediation recommendations.
- Vulnerability Assessment: A comprehensive list of all vulnerabilities discovered during the pen testing, including a prioritization of findings based on risk and impact.
- Evidence: Screenshots, log files, and other evidence supporting the findings and recommendations in the report.
- Action Plan: A plan for remediating and mitigating the vulnerabilities identified during the pentest, including timelines and responsible parties.
A presentation or briefing for the relevant stakeholders, including a summary of the findings and recommendations, and any recommendations for further action could be prepared. After a follow-up pen testing to check whether all identified vulnerabilities were removed, we issue a Pentest Certificate, which can be used for compliance audits and customer communications.

Penetration Testing Methodologies
Our penetration testing services follow established methodologies to ensure thorough and effective security assessments. We utilize standards and frameworks specific to our targets, including OWASP (Web and Mobile Security Testing Guides), NIST, SANS Penetration Testing Methodology, CREST, and PTES. These methodologies provide a comprehensive approach to identifying and addressing more specific vulnerabilities, covering areas like data storage, API security, session management, cryptography, etc.
Tools
Our experts tailor their tools based on the testing type—whether a black box, gray box, or white box—and the unique features of our targets. We use a variety of industry-standard tools, including Nmap, Metasploit, Nessus, Burp Suite, sqlmap, OWASP ZAP, Wireshark, and Kali Linux, alongside specific tools such as IronWASP, Acunetix, Beef, Red Team Toolkit (RTTK), EternalBlue, and more. This robust toolset enables us to simulate real-world attacks and uncover potential security flaws in web, mobile, network, and cloud environments.
