Quick Answer
DuoCircle continued its sponsorship of Let's Encrypt for a second consecutive year in March 2019\. Let's Encrypt is a free, automated, open Certificate Authority run by the nonprofit Internet Security Research Group (ISRG), funded entirely by sponsorships. DuoCircle uses Let's Encrypt SSL certificates inside its Advanced Threat Defense system; the certificates are issued for client domains so users have a verifiable SSL indicator when clicking through to safe links from email. Sponsorship places DuoCircle alongside Cisco, Facebook, and Google in supporting ISRG's mission to make encrypted connections universal.

_Duocircle, a web-based email security solutions company, has chosen to sponsor Let’s Encrypt for the second year in a row. Let’s Encrypt is a service provided by the non-profit Internet Security Research Group. Let’s Encrypt gives people free digital certificates because they want to create a more secure and privacy-respecting web._
**San Diego, CA, March 22, 2019**, DuoCircle is an integrated, cloud-based email security solutions company. DuoCircle is sponsoring Let’s Encrypt for the second year in a row.
Let’s Encrypt is a free, automated and open certificate authority (CA), run for the public’s benefit. It’s a service provided by the Internet Security Research Group (ISRG). Let’s Encrypt provides the digital certificates domains need in order to enable HTTPS (SSL/TLS) for their websites, for free. They do so because they want to create a more secure and privacy-respecting web.
[DuoCircle](/) is sponsoring Let’s Encrypt for a second year because the company prioritizes privacy and understands the need for encryption on the web. “We are passionate advocates for free speech and the need to make encrypted connections ubiquitous online,” said Brad Slavin, CEO of DuoCircle. ISRG, which provides Let’s Encrypt, is a non-profit organization. As such, it relies on sponsorships like those from DuoCircle to be able to offer its service for free. “It’s nice to be in the same category as world class organizations like Cisco, Facebook and Google in sponsoring such an important organization as Let’s Encrypt,” said Mr. Slavin.
Email is still the number one threat vector for malware, ransomware and business email compromise. Today’s most pressing cybersecurity challenge is reliably and accurately detecting and blocking threatening emails before they can do damage.
Forging an email is surprisingly easy. Today’s cybercriminals have no problem forging emails from reputable, well-known companies or even from executives within the corporations they seek to attack. This makes it difficult for employees to determine which emails to trust. Only a comprehensive threat detection system, that can determine the origin servers of incoming emails, can reliably verify incoming messages. Let’s Encrypt’s SSL certificates are a key component in offering this protection.

DuoCircle is not a web hosting company which benefits directly from issuing SSL certificates. However, in the enterprise IT environment, the risk of phishing and domain name forgery is high.
DuoCircle combines Let’s Encrypt certificates with their Advanced Threat Defense technology. When combined with Advanced Threat Defense, it gives users an immediate way to reliably verify safe emails. “We specifically engineered our Advanced Threat Defense system, for malware and Phish Protection, to utilize Let’s Encrypt SSL certificates for our client domains,” said Mr. Slavin.
