Advocating the Benefits of Open Source for Email Security

Guardian Digital is the premier open-source email security company and a strong proponent of the open-source development model. We were founded as an internet security provider and have since narrowed our focus to email security because cyber threats to businesses primarily originate in email. Guardian Digital relies on highly secure purpose-based open-source programs that provide customers with the most effective and comprehensive email security solutions. These solutions are designed to offer businesses reliable protection against the latest and most sophisticated email security threats. As an active contributor to the Linux community and as the sponsor of LinuxSecurity.com — the go-to resource for news, information, and articles on Linux and open source — Guardian Digital strives to educate society on the myriad benefits that open source offers both to enterprises and individuals.



Open-source development is transparent and collaborative. Developers are able to access code and communicate with other experts in the open-source community. They discuss the development of features and work together to solve problems. The collaboration that is inherent to open-source development leads to exceptional levels of innovation and results in the highest quality products.


Open source products are often more secure than proprietary alternatives. The visibility of open-source code provides developers and engineers with access to open-source projects. As a result, open-source experts around the world are able to review and improve upon open-source programs. Because open-source products are thoroughly reviewed by the community, vulnerabilities are detected and fixed very rapidly. This results in exceptionally secure products.


Freedom and Flexibility

Open-source programs are standards based and freely accessible.  Thus, individuals and enterprises can avoid the risk of vendor lock-in by choosing open-source solutions. By contrast, using proprietary software can force people and businesses to continue relying on a product. Even if they are unsatisfied or if the product price increases, they lack the flexibility and freedom to escape, 

Cost Effective

Open-source products are not free, but they are more cost effective than proprietary solutions. For instance, proprietary software requires licensing fees, which automatically drive the prices of proprietary products up compared to the prices of alternative open-source options. Additionally, upgrading your proprietary software generally requires either a new license or a new software suite.


Community Values

Following old business principles of ownership, proprietary products are developed with the main goal of benefitting the vendor. Modern and flexible, open-source developers aim to create products that are as effective and useful to the community as possible. Open-source engineering is supported by a community that shares the common goal of creating and improving solutions so that they will offer the most benefits possible to both businesses and society as a whole. Moreover, the vast and vibrant atmosphere that surrounds open-source development has much more to offer in terms of innovation and problem solving than small private groups working on proprietary solutions.

Becoming Increasingly Popular

More enterprises and individuals than ever before are choosing open-source solutions over proprietary products. This increase in popularity is providing the open-source community with support and resources, enabling open-source development to continue evolving and improving. As a result, open-source products maintain a leading edge over often stagnant and outdated proprietary technology.


The Future of Digital Security Is Open Source

According to ZDNet, 78 percent of companies of all sizes across industries are now choosing open-source software over alternative proprietary solutions. This trend is likely to grow as more businesses recognize the competitive advantage that open-source solutions offer in terms of product quality, security, and freedom from vendor lock-in. Guardian Digital is extremely pleased that open-source software is becoming increasingly prevalent and that a large percentage of the tech society, and by extension our broader communities, are benefiting from open-source development.
