Every Redlings pentest is subject to strict guidelines and ethical principles.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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
- Red Teaming
- Active Directory Security Assessment
- IoT/Hardware Security Assessment
- Social Engineering
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 results of the performed pentest are discussed in a final meeting. We are aware that the aware that the security problems found are only a first step. Concrete follow-up measures to to increase security must be defined and 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 Köln, 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.
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.
This can vary - depending on the type of pentest. However, the following points are often part of the scope or the mutually reached agreement:
- Target systems (IP/host name) or IP address spaces
- Test periods as well as contact persons
Cloud providers such as AWS, Azure, and Google have provided blanket consent forms for certain areas, but this may vary by provider. In principle, one must be available if the systems to be tested are not on your own infrastructure. It is often useful to involve the system managers concerned in the planning process at an early stage so that the "pentest" is not perceived as an attack but as a potential analysis for improving IT security. To be honest, we are not interested in showing that we can hack a company, but to uncover potential for improvement in the IT landscape in a collaborative working atmosphere, deriving and prioritizing measures and improving IT security as effectively and efficiently as possible.
Admittedly, this is not so easy - if someone tells you that they only work with the best pentesters, this may be difficult to verify.
that they only work with the best pentesters, it may be difficult to verify.
Pentesters with more experience and more extensive training
are often more expensive. Just remember that you get what you pay for.
Beware of pentesters who offer prices that are too good to be true.
They are probably not doing a thorough job.
I suggest looking for penetration testers who have one or - better - several recognized
Among the most respected (and costly) certifications in security circles in the in the field of penetration testing are the certifications of Offensive Security (esp. OSCP - Offensive Security Certified Professional, OSCE - Offensive Security Certified Expert) and SANS/GIAC.
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.
At the beginning of the process, we try to familiarize ourselves with your company and the scope of work
so that we are able to provide an accurate quote.
We gather this information on purpose so that we don't come back
and ask for more testing time (and additional costs).
The more information you are willing to share with us,
the better we can provide an estimate.
However, some customers want a black box approach, where only a limited amount of information is provided, to simulate a real attack and the response to it. In this case, we still need to capture the size/complexity, that is required for testing, and therefore have some fundamental questions about scope.
