Notably, SpamHero doesn't need to be informed about the validity of your domain's email addresses. Instead, it learns directly from your domain's email activity throughout the trial phase. Unlike other systems that depend on complex algorithms vulnerable to spammer tactics, SpamHero utilizes a rule-based spam filtering approach. This method encompasses millions of continuously updated rules, maintained around the clock by both automated systems and dedicated human experts. Additionally, we incorporate well-known virus scanners to effectively prevent viruses, a practice common among many spam filtering solutions.

More than 90% of targeted cyber attacks begin with spear phishing emails, underscoring the urgent requirement for enhanced mail server security. Unfortunately, many current security measures, such as the basic protections found in Microsoft® Exchange™ 2013 and 2016, rely on outdated pattern file updates that mainly detect traditional malware. These approaches often fall short in their ability to identify malicious URLs or document exploits, which are common in sophisticated attacks and advanced persistent threats (APTs). On the other hand, ScanMail™ Suite for Microsoft® Exchange™ takes a proactive stance against highly targeted email threats and spear phishing by utilizing advanced document exploit detection, a superior web reputation system, and sandboxing, all integral to a customized APT defense strategy that competitors do not offer. Additionally, ScanMail stands out by providing the capability to block conventional malware through its advanced email, file, and web reputation technologies, coupled with global threat intelligence gathered from the Trend Micro™ Smart Protection Network™ cloud-based security, thereby delivering extensive protection for your mail server.

Introviz provides cutting-edge, patented solutions aimed at addressing the increasing risks posed by cybersecurity threats to corporate systems. The struggle for IT security has its roots in efforts that began decades ago at key network entry points, such as routers and firewalls. Traditionally, many organizations have depended on adept network engineers to protect against cyber threats, which often results in an illusory sense of safety. However, in recent times, the landscape of cybersecurity threats has shifted toward the less monitored "back door" entry points, particularly via employees' web browsers. As workers connect to various networks—whether at work, home, or in public—there’s a risk that they may inadvertently allow external trackers and advanced zero-day malware into the corporate environment. Conventional defenses like Anti-Virus software, VPNs, and firewalls prove insufficient in managing the risks linked to browser content. As a result, web browsers have become a main channel for phishing attacks and malware entry, raising the alarming possibility of threats spreading from individual devices to the broader corporate network. This evolution highlights the urgent requirement for sophisticated protective strategies specifically designed to address vulnerabilities associated with web browsers, ensuring that organizations can better safeguard their digital infrastructures. Enhanced awareness and training for employees about these risks will also be critical in fortifying defenses against potential cyber intrusions.
