Redefining Business Email Security: Guardian Digital's Innovative Open-Source Strategy

Jul 10, 2023 -- N.J. Guardian Digital today announced its solution to the rise in phishing and zero-day attacks threatening businesses via its comprehensive email protection system, EnGarde Cloud Email Security.

Today’s email-borne cyberattacks are more targeted and evasive than ever before, and Guardian Digital’s own data from millions of emails received and analyzed confirms Fundera’s findings that phishing-related threats are growing rapidly. Fundera reported a 424% increase in new small business cyber breaches last year, over 90% which can be attributed to a phishing email according to Verizon.

EnGarde offers businesses complete phishing and zero-day attack protection at competitive prices through a unique combination of transparent, collaborative open-source development, expert ongoing system monitoring, and real-time cybersecurity business insights.

Open Source: An Underused Tool Against Cybercrime

Open source has been instrumental in establishing secure internet communication since the Internet's birth, with influential roles in email delivery and powering 96% of the top million web servers worldwide. However, it's surprisingly underused in email security, providing potential solutions to phishing and zero-day attacks.

The open-source development model involves a global community creating, testing, and refining technology. This "many eyes" approach ensures high security levels as potential vulnerabilities are quickly found and fixed.

In an open-source approach to email security, emails from millions of worldwide systems identify patterns and support extensive testing on malicious email blocking filters. The feedback given is integrated into systems across the globe. This Open-Source Intelligence (OSINT) provides real-time updates to halt and resolve novel phishing attacks and zero-day vulnerabilities before widespread propagation.

Unlike proprietary models, open-source email security providers can leverage shared global resources and intelligence, empowering them to develop secure, resilient, and affordable solutions that can swiftly adapt to stay ahead of evolving threats.
