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.
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.
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.
Training of the internal IT team
The results of a penetration test can help your developers and administrators make fewer mistakes. A pentest detects misconfigurations, programming errors and other vulnerabilities.
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.
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.
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.
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.
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
- Wireless Penetration Test
- Social Engineering
- Cloud Penetration Testing
- Red Teaming
- Active Directory Security Assessment
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 Düsseldorf, 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.
The terms "penetration tester" (also "pentester" for short), "white hat hacker" and "ethical hacker" are often used interchangeably. The terms "ethical hacker" and "white hat hacker" cover all hacking activity aimed at improving IT security. What they all have in common is that activities that are illegal or do not comply with the Code of Ethics are refrained from.
Formally, a penetration test is only an "ethical hack" with very clearly agreed rules, a formal procedure as well as a defined goal.
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.
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.
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.
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.
