Security is just an IIIusion

Even companies with excellent protective measures realise that in cyberspace 100% security is not achievable. There are a lot of more or less mature security products and processes, but the number of existing vulnerabilities in software lies in an astronomic range. And security products are no exception.

SERPENTEQ strives to help companies in detecting and mitigating vulnerabilities holistically and systematically. We want our customers to know all critical risk and to make the right decisions for their business based on that knowledge. This only works when we as consultants discuss benefits and limitations of security measures in an open and honest way.

We want to express this philosophy of an open and honest approach with our maxim "Security is just an IIIusion".

What we offer

  • wb_incandescent

    Awareness Workshops for Managers (SQ-AWM)

    We have seen many security initiatives where companies spent months testing but "overlooked" their entire SAP landscape. Because management frequently doesn't know that the SAP landscape is more complex than any other part of their IT infrastructure.

    We offer 1/2 day awareness workshops that help managers understand the magnitude of risks in their SAP landscape.

    Cyber-Security Assessments / Penetration Tests (SQ-CSA)

    Cyber-crime is a growth industry. Therefore cyber-security is a must-have for all companies in order to protect their competitive advantage, productivity and good image. In defense against cyber-attacks, there is no second chance. Our experienced experts can provide you with a 360° view of your SAP cyber-risks.

    We offer comprehensive assessments of critical and exposed systems in your IT/SAP landscape.

    Code Reviews (SQ-CORE)

    It only takes one coding flaw for a hacker to break into your most critical systems. We have reviewed millions of lines of code for various types of implementation, design and architecture flaws. We are deeply familiar with the benefits and limitations of code scanners. And we are convinced that when it comes to critical applications, there is no substitute for a human tester's ability of lateral thinking.

    We offer manual code analysis of critical applications (SAP, HANA, Web) for C/C++, ABAP, Java and other web scripting languages.

    Custom Security Trainings (SQ-CST)

    The only thing worse than making mistake is repeating mistakes. In every Cyber-Security Assessment we uncover vulnerabilities and provide advice to mitigate them. But companies benefit even more from our work, if they send their teams to our customized trainings that teach them how to avoid the exact vulnerabilities found on their systems in the future.

    We offer 2-5 days customized security workshops that provide developers with detailed knowledge of the most dangerous and most common mistakes found in their applications.

Who we are

Our team comprises experienced security analysts that have reported several hundred so-called "Zero Day" vulnerabilities in standard software to the respective vendors and helped mitigating them. We present stunning output from our research in professional articles, at security conferences and workshops on a regular basis. Our core area of security expertise lies in SAP technologies and code audits of exposed systems of any technological kind.
