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.
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.
One of the most dangerous tactics used in cyber attacks is to send seemingly harmless links in emails that only lead to phishing sites or malware after they have been received. Traditional spam filters and virus scanners quickly reach their limits here, as they only check emails once when they are received. But what happens if the link later becomes dangerous? This is exactly where Time-of-Click Protection (ToC Protection) comes in. In this article, we show you how Time-of-Click Protection works, why it is indispensable for companies, and how it is integrated into URL Safeguard in NoSpamProxy.
Since the introduction of DMARC (Domain-based Message Authentication, Reporting and Conformance) in 2015, the protocol has established itself as an integral part of email security. However, with the increasing complexity of email infrastructures and ever new requirements for interoperability and clarity, it was time for an update. This update is called DMARCbis and brings with it some significant changes.
Authenticated Received Chain (ARC) complements existing authentication methods such as SPF, DKIM and DMARC and ensures that emails can also be reliably verified for forwarding or via mailing lists. ARC offers decisive advantages for delivery security, especially in cloud-based environments. In this article, you can find out why it is worth activating ARC now, and how you can easily implement it in NoSpamProxy.
SVG files seem harmless, after all, they are known as simple graphics for the web and design. But it is precisely this underestimation that makes them particularly attractive to cyber criminals. Manipulated SVGs are increasingly being used to spread malicious code or steal login data. Find out how these attacks work and how you can effectively protect yourself against them.
Email is and remains the most popular gateway for cyber attacks. Traditional spam filters are no longer sufficient. Modern threats such as targeted phishing, CEO fraud or ransomware are so sophisticated that they can bypass conventional protection mechanisms. This is exactly where Advanced Threat Protection (ATP) comes in: as an intelligent, multi-layered defense mechanism against current attack scenarios. NoSpamProxy includes a wide range of ATP functions as standard, which do not require additional licensing. Read our blog article to find out why ATP is so important and why NoSpamProxy effectively protects you and your company against threats.
A company’s success is also based on a strong focus on customer satisfaction and sustainable support. Customer Success Management (CSM), which accompanies and supports customers from day one, plays a key role in this. Today we talk to Tim Kaleja, Competence Lead Customer Success at NoSpamProxy, about the opportunities and challenges in customer dialog and what makes Customer Success Management at NoSpamProxy so special.
