Sustainable security culture

Awareness technology

  • Awareness Engine
  • Employee Security Index (ESI® )
  • Patented Spear-Phishing-Engine
  • Security Hub

Special focus on protection of employee- & data privacy

Every technology is designed to enrich human beings. If a person is able to use a technology, he can achieve great things.

There is often the feeling that IT security in general does the opposite: IT security systems prevent the user of being productive and users are the biggest threat to IT security.

We believe that it is time to reunite IT security with the user.

We believe that by empowering themselves, people can regain the freedom and confidence to do more with modern technology.

We believe that every person makes an important contribution to everyone’s IT security. Therefore, we want to start with the human factor and thus together make our digital society and economy secure.

For a safe society and against fake news

IT-Seal supports „Journalismus macht Schule“

As an IT security company, we are committed to a sustainable security culture. We are not only active on behalf of our customers, but also want to help society as a whole to develop a culture of security.

That’s why we support the “Journalismus macht Schule” (JMS) project, which raises young people’s awareness of fake news and other risks on the Internet: For every new customer acquired, we donate to the Verein zur Förderung von Informations- und Nachrichtenkompetenz e.V. (Association for the Promotion of Information and News Literacy), thus financing one awareness workshop for each school class.
