Press Releases

Oct 29, 2021 -- United States - Guardian Digital the premier open-source email security company, is using a unique combination of transparent, community-powered open-source development, expert ongoing system management and support services and real-time cybersecurity business insights to address increasingly sophisticated, ever-evolving email threats like spear phishing, ransomware and zero-day attacks.

The Modern Threat Landscape Is Complex & Dynamic

Over 90% of the cyberattacks and breaches that cripple businesses of all sizes daily with data loss, extensive downtime and severe, lasting reputational harm can be attributed to phishing. Zero-day attacks - or attacks exploiting a vulnerability before developers have had the opportunity to release a fix for it- are also becoming increasingly prevalent and problematic. Seventy-four percent of threats detected in Q1 of 2021 were zero day malware, or malware that does not match any existing antivirus signature, and thus goes undetected by traditional signature-based antivirus and endpoint security solutions.

The pandemic has led to an increased reliance on cloud email - which is highly vulnerable to attack without critical additional security defenses in place - to accommodate remote workers, providing cyber thieves with the ideal environment to launch malicious attacks designed to steal credentials, compromise accounts and spread dangerous ransomware. The homogeneous architecture of popular cloud platforms like Microsoft 365 and Google Workspace makes it easy for attackers to bypass static native email protection. Cyber criminals can open any account, test their methods until they are able to bypass default filters, and reuse these methods in attacks targeting thousands of different accounts. Many of these scams employ social engineering tactics to manipulate psychology and stealthy fileless techniques to evade detection, making them even more likely to be successful. It is no surprise that despite the built-in email security provided by Microsoft Exchange Online Protection (EOP) in Microsoft 365, 85% of users have experienced an email data breach in the past year.

In this heightened digital threat environment, intuitive, adaptive email security defenses are needed to prevent attacks and make email safe for business, and the open-source development model provides a superior vehicle for engineering the caliber of protection required to combat modern phishing campaigns and zero-day exploits.

Open Source: A Powerful, Yet Underutilized Weapon in the Fight Against Phishing & Zero-Day Attacks

Since the inception of the Internet, Open Source has played a critical role in the development of the technologies and protocols that secure communications, and continues to power the Internet to this day. Email is powered by open standard protocols like SPF, DMARC and DKIM, and 67% of all web servers worldwide run on the open-source Linux OS. That being said, open-source development is shockingly underutilized in the realm of email security - and holds great promise in the ongoing fight against phishing and zero-day attacks.

In the collaborative, transparent open-source development model, developers, programmers, engineers and community members worldwide work together for the greater good to create, test and improve upon software and technology. The “many eyes” of the open-source community constantly scrutinizing open-source code results in exceptionally secure products and solutions, as vulnerabilities are rapidly identified and eliminated.

In an open-source model applied to the development of email security solutions, emails gathered from millions of systems from around the world are used to identify patterns and perform large-scale tests on filters and frameworks that have been developed to block malicious email. Results are then distributed back to the community, where the insight gathered is incorporated into millions of systems worldwide. The Open-Source Intelligence (OSINT) gathered in this process results in real-time updates that help to contain and remedy new phishing campaigns and zero-day vulnerabilities discovered in one part of the world before they have a chance to spread.

Unlike in a proprietary development model, open-source email security providers can freely tap into global resources, tools and intelligence shared within the vibrant open-source community, equipping them with the input required to engineer exceptionally secure, resilient and cost-efficient solutions capable of evolving and growing quickly and easily to remain ahead of the threats that challenge their defenses.
