during a cyberattack?

As an organization, you want to respond swiftly to risks like cyberattacks. Such attacks often occur due to security vulnerabilities in your company's software. But how do you ensure that you can be reached when there is a vulnerability in your web server? The Digital Trust Center has introduced security.txt as a solution.

What is security.txt?

Security.txt is a simple text file containing your contact information that you place on your web server. This file makes it easy for cybersecurity researchers to reach you, enabling you to protect your company and take swift action in the event of a cyber threat. With security.txt, notifications go directly to the appropriate person.

Implementing security.txt in 3 simple steps:

  1. Determine the Recipient: Decide who should receive the notifications—your company or your IT service provider.
  2. Create the File: Visit, fill out the form, and generate the text file. This file will contain the contact address for security vulnerabilities and the expiration date.
  3. Deploy the File: On your web server, create a directory named .well-known and place the file there.

Now you understand how important and simple it is to implement security.txt. We highly recommend implementing security.txt as soon as possible. For more information about security.txt, visit the Digital Trust Center. Need help with the implementation? Contact us at
