Priorisierung von IT-Risiken
With a penetration test you can determine which existing vulnerabilities have the greatest impact on your web applications and network. on your web applications and network. Use your resources and time more efficiently.
Training of the internal IT team
The results of a pentest support the own team - e.g. system admins - to avoid some error sources in the future. A penetration test can reveal errors in configuration and programming.
Implementation of Security Policy
Are important patches missing or are applications and operating systems not hardened? If your pentesters can show that applications and network areas with good implementation have fewer security vulnerabilities, this often has the effect of motivating them to follow the security guidelines.
Detection of vulnerabilities
Penetration tests attack your network and web applications like a hacker would - but without causing any damage. This allows you to find and fix vulnerabilities before the attackers do.
Protect your most important data and the trust of your customers
Company and customer data is considered the lifeblood of a business and can be extremely damaging in the wrong hands. With a pentest, your company can better protect its data assets and, if possible, prevent attacks.
Increase the effectiveness of your security investments
Often, our penetration testers uncover unused potential of existing security technologies. The performance of security systems can often be significantly increased as a result.
Investments in security measures should always be supported with concrete evidence to demonstrate the value to the business. By showing your leadership team the value of an investment, you can justify your need for more resources.
Konsequenzen eines Understand Cybersecurity Incidents
Penetration testing gives you unvarnished feedback on the possible consequences of an IT security incident such as a ransomware attack.
Regulations such as PCI-DSS, but also ISO 27001/2 and others, may require regular penetration tests. Some contractual regulations may also contain such a requirement.
Steps for a Penetration Test
The project schedule is planned and prepared during the joint kick-off meeting. Among other things, the following points will be discussed:
- Reconciliation of contact details
- Test period with start date and end date
- Review of the exact handling and scoope of the pentest
- Technical presentation by the customer (test subject)
- Making technical details available (e.g. documentation of components, accesses)
- Agreement on the environment of the pentest and the exact methodology
Penetration Test Execution
Now the security test takes place. Here, it usually consists of one (or more) commissioned test modules.
- Internal Network Penetration Test
- External Network Penetration Test
- Web Application & Web-API penetration test
- Cloud Penetration Testing
- Wireless Penetration Test
- Red Teaming
- IoT/Hardware Security Assessment
- Active Directory Security Assessment
The test results are compiled in a report. This will include, among others, the sections listed below:
- Summary of the results and description of the framework of the project
- Listing and description of security vulnerabilities found with risk assessment and remediation actions
- Proof documentation on the security vulnerabilities, screenshots if necessary
The penetration test and its result are discussed in a final meeting with all parties involved. We understand very well that the discovered and documented security vulnerabilities are only the first step. Concrete measures for the improvement of IT security must be derived and also implemented.

Check what damage hackers can do to you with a penetration test.
As a pentester and ethical hacker, we emulate attacks on corporate IT using the same tools and methods that criminal organizations use every day in Essen, Germany, Europe and worldwide.
So erreichen Sie uns
A penetration test, or "pentest" for short, is a security check that emulates an attack by a malicious party on a network or application to identify security vulnerabilities. This test is coordinated in advance and conducted in such a way that no system is damaged. At the end of the test, you will receive a report that includes the problems and vulnerabilities found, along with suggestions on how to fix them.
Both penetration testing and automated vulnerability scanning are useful tools for identifying technical risks and security vulnerabilities.
Although they are different testing methods, they complement each other and should both be performed.
A vulnerability scan is an automated, low-cost method for testing common network and server vulnerabilities. This is sometimes referred to as automated pen testing. There are many automated tools available, and most can be easily configured by the end user to scan for published vulnerabilities on a scheduled basis. While an automated vulnerability scan is very efficient and cost-effective at identifying common vulnerabilities such as missing patches, service misconfigurations, and other known vulnerabilities, they are not as accurate at verifying the correctness of vulnerabilities, nor do they fully determine impact through exploitation. Automated scanners are more prone to reporting false positives (falsely reported vulnerabilities) and false negatives (unidentified vulnerabilities, especially those affecting web applications). Automated vulnerability scanning is mandated by the Payment Card Industry Data Security Standard (PCI DSS).
Well-known vulnerability scanners include and OpenVAS. Examples of scanners that specialize in finding web application vulnerabilities are Netsparker Security Scanner and Acunetix Vulnerability Scanner.
A penetration test focuses on the environment as a whole. In many ways, it picks up where scanners leave off to provide a comprehensive analysis of the entire security posture. Although scripts and tools are used by a penetration tester, their use is largely limited to reconnaissance activities. The majority of a penetration test is manual in nature. A penetration test identifies vulnerabilities that scanners cannot detect, such as vulnerabilities in wireless systems, vulnerabilities in web applications, and vulnerabilities that have not yet been disclosed. In addition, a penetration test involves attempts to securely exploit vulnerabilities, escalate privileges, and ultimately demonstrate how an attacker could gain access to sensitive information assets. Penetration testing also often involves the use of company-specific "test scenarios."
Penetration testing and automated vulnerability scans both serve a purpose, and both types of tests belong in a comprehensive vulnerability assessment program. Automated vulnerability scans should be performed at regular intervals, ideally at least weekly, while network penetration tests should be scheduled quarterly or when significant changes to the environment are planned.
In black-box testing, the pentester attempts to attack the target without any prior knowledge of addresses, systems, applications and processes. The main argument for this approach is that this scenario comes closest to the real world and thus simulates a real attack scenario. However, this is only partially true because a real attacker does not have just a week or two like a contracted pentester, but has the entire time, including months or years, to prepare the attack. In fact, some of the most successful hacker attacks have taken place over a period of up to 12 months.
This bias means that black-box testing is often inconclusive and gives customers a false sense of security. Redlings therefore recommends black-box testing only in exceptional cases. The argument that attackers (must) implement a black-box approach also only works to a limited extent, since a long preparation time can lead to extensive internal informtions.
As with any business service, the cost of a penetration test varies significantly depending on several factors.
significantly depending on several factors.
Scoping details such as network IP addresses, complexity and number of (web) applications and employees for social engineering are key factors in determining project size. Taking these variables into consideration, our team works diligently to, align the scope details with your organization's security requirements.
Nevertheless, some empirical values that can serve as an initial guide can be mentioned. A high-quality, professional pentest performed by experts usually costs usually from about €10,000, but can be for large projects also significantly above this amount.
Redlings also offers discounts for multi-year contracts ("continuous pentesting") to ensure, that your company has a consistent pentesting partner, and can can stretch the security budget further.
The scope of a penetration test should always be jointly adapted to the specifics of the company as well as the system to be tested.
In the case of a Web application, the scope often consists of the server and operational landscape as well as the user interfaces and APIs. Often, there are enterprise applications that have been specifically was written and that you want to have looked at.
Other considerations also play a role in a network pentest. In particular, the scope you choose should include mission-critical systems that would Could compromise security in the event of a compromise, e.g. because they store sensitive data, such as user information, passwords or customer data.
An IT security audit examines the security of a company's IT systems from a holistic perspective. Security threats can arise not only from attacks, but also from technical incidents, organizational deficiencies or force majeure.
Security audits often take place as part of an ISMS (information security management system) and examine not only technical security elements but also compliance with the company's own standards and guidelines, security processes, employee training (keyword information security awareness) and similar aspects. Some security audits also include elements of a vulnerability scan.
However, a security audit usually does not go into as much technical detail as a manual penetration test.
