What is security.txt used for?

By MailChannels | 3 minute read


In the ever-evolving landscape of cybersecurity, where new threats emerge with daunting frequency, it’s critical for organizations to foster an environment of open collaboration and swift communication. Enter security.txt, a beacon of hope for infrastructure providers and security professionals alike. This proposed standard, simple yet profoundly impactful, is paving the way for a more secure digital world. But what exactly is security.txt, and why is it becoming an indispensable tool in the arsenal against cyber threats?

For those just dipping their toes into the complex world of cybersecurity, security.txt serves as a guidepost. It’s a text file, placed at a well-known path on a website, that spells out how to report security vulnerabilities. This straightforward approach not only makes the lives of security researchers easier but also signals a company’s commitment to protecting its digital assets. 

At MailChannels, we’ve seen firsthand the benefits of adopting this protocol—from enhancing communication clarity to building community trust.  We believe adopting security.txt is not just good practice, but essential for infrastructure providers:

1. Clarity in Communication: It offers a clear and standardized way for security researchers to contact us. In the complex landscape of cyber threats, effective communication channels can mean the difference between a quickly resolved issue and a full-blown security incident.

2. Demonstrating Commitment to Security: By implementing security.txt, we send a strong message to our customers and the industry at large that we are committed to the security of our systems and are proactive in our approach to identifying and mitigating vulnerabilities.

3. Streamlining the Disclosure Process: The file can include directives such as contact information, encryption keys for secure communication, and policies around vulnerability disclosure. This streamlines the process for researchers, making it easier for them to report issues without unnecessary hurdles.

4. Building Community Trust: Engaging with the security research community in a transparent and positive manner helps build trust. It shows that we value their contributions and are serious about working together to secure our infrastructure.

5. Legal Protection: Properly configured, security.txt can also include legal statements that protect both the reporter and the company during the disclosure process, ensuring that well-intentioned research is not met with unwarranted legal action.

At MailChannels, we understand that security is a journey, not a destination. Implementing security.txt is just one of the many steps we are taking to ensure that our infrastructure remains secure, resilient, and trustworthy. We encourage other infrastructure providers to join us in this initiative, enhancing the security ecosystem for everyone.
