Your advantages at a glance
With our penetration tests and security audits, Redlings reliably identifies security vulnerabilities that put our customers at risk. Benefit from our experienced penetration testers.
Our Cyber Security Experts
Over many years, our pentest experts have gained experience in performing technical security audits and penetration tests. Ongoing training and qualifications ensure that they are always up to date with the latest the latest attack techniques.
Who we are
Redlings is a EU/Germany-based company specializing in penetration testing.
Ensure your defenses are up to current threats. With our manual deep-dive engagements, we identify security vulnerabilities security vulnerabilities that put customers at risk. Through our Continuous Collaborative Testing service offering, we take a long-term security approach and work with our customers to ensure that their security posture is constantly improving.
Every Redlings pentest is subject to strict guidelines and ethical principles.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
- Pentest Network (internal)
- Pentest Network (external)
- Web Application & Web-API penetration test
- Active Directory Security Assessment
- Cloud Pentests
- Social Engineering
- IoT/Hardware Security Assessment
- Wifi Pentest
The test results are compiled in a report. This will include, among others, the sections listed below:
- Short version of the results and presentation of the framework parameters
- List and presentation of the detected security issues with assessment of the risk as well as suggestions for correction
- Detailed documentation of discovered security vulnerabilities
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 Hamburg, 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.
One question that is not asked often enough is how much of the testing is automated
and how much is manual. Automated tools, especially at the beginning of a project, can save
save a pentester a lot of time and their use also depends on the project.
However, experience shows that about 90-95% of the pentest is "manual work".
This is not to say that automated vulnerability scanners do not add value; Vulnerability scans are quick and easy tools that should be used on a regular basis to should be used to identify missing patches or outdated software in larger environments.
In a white-box test, the pentester receives all relevant information about the target system(s). The advantage is that this approach saves time - and thus costs. It is also generally true that white-box tests are more effective in improving the security of IT systems and should usually be preferred.
Generally speaking, black-box testing can be a suitable means of uncovering security issues against a specification (e.g., a Web API interface), but is very poorly suited to identifying flaws within specific components. In the latter case, white-box testing should be the preferred means.
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.
Similar to cost, the duration of penetration testing depends on several factors. Penetration testing is a hands-on assessment that does not lend itself to short, quick sprints. At Redlings, we tend to have pentesting projects start at week or so, but many projects can extend over a much longer period of time. extend over a significantly longer period of time.
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.
