SPF (websec.nu)
v=spf1 include:_true.websec.nu -allA missing, incorrect or weak SPF record poses enormous risks:
Email spoofing: Without an SPF record, there is a risk that attackers can send spoofed emails on behalf of the domain.These spoofed emails can be used to carry out phishing attacks, which can steal sensitive information such as usernames, passwords or financial data, or malicious code such as ransomware to distribute.
Deliverability problems: If the SPF record is missing or corrupted, this can lead to significant problems with email deliverability, email filters and spam -Filters can classify domain names without a valid SPF record as suspicious and treat emails from these senders as potential spam or block them.
Reputation damage: If fake emails in the If a domain name is sent, this can permanently damage reputation and trust. Especially if customers and business partners are harmed as a result and it becomes known that this could have been avoided.

IT basic protection for your domain
The security of your domain and all associated services is a cardinal task. The legislator requires the monitoring of essential risks, not only through the applicable data protection and other legal framework. In the IT-Grundschutz Compendium (February 2021) the Federal Office for Information Security (BSI) has defined numerous measures to optimally secure domains and the associated services.
Failure to comply with IT basic protection involves a significantly increased risk of current dangers such as spoofing, identity theft or DNS-DDoS. In addition to financial damage, reputational damage is often the result, which can permanently damage the image of the company. There is also a risk that insurance companies will refuse to pay in the event of damage because the necessary protective measures have not been taken and the status of the technology has not been implemented.
