Using the Electronic Court and Administration Mailbox (EGVP) with NoSpamProxy

Digitization has also led to fundamental changes in the legal and administrative sectors. One of the most important developments was the introduction of the Electronic Court and Administration Mailbox (EGVP), which enabled the secure exchange of documents between citizens, companies, lawyers, authorities, and courts. The EGVP has since been replaced by specialized electronic mailboxes such as beA, beN, beBPo, beSt, and eBO—each with a clearly defined scope of application. The following overview shows the development from the original EGVP to today’s solutions and explains how they work in practice.

Phishing with fake automobile brochures

The used car trade is booming like never before—especially online. The multitude of platforms and digital marketplaces makes business easier, but also attracts criminals. Prospective buyers are always potential targets for fraudsters who use increasingly sophisticated scams to try to obtain money or sensitive data. One particularly dangerous scam is phishing with fake car catalogs. Victims receive seemingly professional offers in the mail, but these are actually the work of organized cybercriminals.

Email penetration tests: How secure is your email security?

Email remains the number one gateway for cyberattacks. Whether phishing, malware, or targeted manipulation—the threats are constantly evolving. This makes it all the more important for companies to regularly review their email security. Email penetration tests are an effective way to do this. They simulate real attack scenarios and uncover vulnerabilities. This gives organizations a clear assessment of how resilient their communications infrastructure really is – and where urgent improvements are needed.

Sandbox explained: Why it is indispensable in modern email security

Cybercriminals are using increasingly sophisticated methods to attack companies and individuals via email. They often cleverly disguise their threats in seemingly harmless attachments or links. Conventional virus scanners are increasingly reaching their limits, as new, unknown malware can slip past them. This is where the concept of sandboxing comes in. Suspicious email content is executed in an isolated, virtual test environment so that even unknown attacks can be detected and repelled before they cause damage. In this blog article, you will learn how sandboxing works as an integral part of modern email security strategies, why it is indispensable in times of zero-day threats, and how the 32Guards Sandbox can provide you with lasting protection.
