Your Website Security Audit
JOUO provides you with insights into the security of your website and whether it meets general legal requirements. We use publicly accessible data for our analyses. We not only provide you with this data in a clearly structured format, we also explain it to you. You also receive specific recommendations for action if weaknesses are found.
With JOUO you can monitor and improve the compliance of your website - without any IT knowledge.
Your individual audit
JOUO analyses the security and compliance of your website with legal requirements
Monitor your security
JOUO informs you on your security vulnerabilities and how you can fix them.
JOUO gives you insights into the information about your server providers. This includes, among others:

Found security vulnerabilities

Open ports

IP addresses and providers

Server locations

Mail server configuration
For each vulnerability found by JOUO, we explain why it can be problematic and what you can do specifically to improve your security.

Check legal requirements
With JOUO you can find out whether your website fulfils the general legal requirements according to data protection laws.
The legal requirements include, for example:

Mandatory URLs
imprint, terms and conditions and data protection sites

Valid SSL certificate
encrypted connection between browser and web server

Externally integrated resources
fonts, plugins or data from other websites
Now new: The JOUO TOMs!
for data protection laws
According to the GDPR, for example, a company is obliged to document its technical and organisational measures (TOMs) to protect personal data.
With JOUO, you can easily create TOMs, automatically add all vulnerabilities and export a joint PDF.



In addition:
Infrastructure Documentation
as PDF for export
You can automatically export the data that JOUO has collected from your website in form of a PDF report for each of your TOMs. This allows you to document your website infrastructure at any time, for both internal and external purposes (e.g. requests in connection with data protection laws).

Also new:
The Shadow Mode
Your digital camouflage shield when things get serious.
Have you found vulnerabilities with JOUO? Then take a deep breath - and go into shadow mode. Before the vulnerability becomes a threat, we encapsulate your affected systems. Inconspicuously and without interrupting operations - and with maximum protection.



We explain everything you need to know
JOUO is self-explanatory and can be used without IT knowledge
Whether general terms or individual matters - we explain it to you. In JOUO, we not only provide you with general explanations in short info texts, but also explain the found weaknesses and give you specific recommendations for action.
Why JOUO is also a compliance tool
JOUO not only checks whether your website meets legal requirements, but can also be used to document your vulnerabilities. After all, security is an important building block for compliance. With our features such as the data history, the Infrastructure Documentation or the JOUO TOMs, JOUO offers great support for your company's compliance.

This can cause the following damage to your company...
JOUO has already scanned...
The scan of a website includes not only the website itself, but also all associated IP addresses and the underlying page content and metadata records. As a result, the figures for page content and metadata records are much higher than for the audit itself.

All data secure in Germany
JOUO was developed in Germany through and through. But that's not all: JOUO stores all data exclusively on German servers, which are certified in accordance with DIN EN ISO/IEC 27001:2017. The operation is carried out by employees of [j]karef GmbH exclusively in Germany.
This means that your data is subject to German data protection law, there is no access by foreign intelligence services and there is physical control over the server locations. The ISO 27001 certificate of the servers is also the highest international standard for information security.

What can JOUO do that others can't?
No IT knowledge required - we explain everything
Not only do we have high-quality analysis results, we also make them understandable for everyone. JOUO is very versatile and suitable for all people.
Data history of your vulnerabilites
The special thing about JOUO is that it not only displays and saves the current status, but also saves all history data. You have a clear overview in the vulnerability history. If you need more detailed historic data, just contact us!
Generate TOMs like no other
Our offer is unique because we can automatically generate a list of your service providers (e.g. web hosting providers) using the JOUO Audit, so you can ensure that your TOMs are complete. You can also duplicate TOMs so that you don't always have to re-enter everything. With our TOMs you can save days of work!
Ongoing further development
JOUO has already come a long way and more is to come. Our development team is constantly working on enhancements that will offer you even better support.

FAQ
What will be scanned for an audit of ‘a website’?
When we talk about "a website", we don't mean a single page (e.g. not just "jouo.de/imprint") but all pages and content that are linked to the domain (in our example: everything that belongs to "jouo.de"). What exactly this is depends on the structure of your website. The JOUO audit shows you everything that belongs to your website.
Which of my data can a hacker see?
A hacker can recognise technical details, server information and potential security vulnerabilities from public data on your website. This enables them to exploit vulnerabilities. The information collected serves as the basis for customised cyberattacks that can lead to data loss, financial damage or reputational damage.
What is the difference between a website and a web page?
A web page is a single page on the Internet, while a website is the entire Internet presence. A website consists of several web pages, just as a book consists of several pages. The website is the complete work, the web page a single page of it.
