I support
Let's Encrypt because
I'm a security nerd.”

JOIN TIMMY. BE A NERD.

AS A PRIVACY-RESPECTING ORGANIZATION, WE KNOW AS LITTLE AS POSSIBLE ABOUT ALL OF OUR SUPPORTERS AND SUBSCRIBERS. AS SUCH, WHILE SOMEONE NAMED TIMMY MAY INDEED BE A NERD AND SUPPORT US, THE TIMMY ABOVE ISN'T A REAL PERSON AND HIS TESTIMONIAL IS NOT AN ACTUAL ONE.

THOUSANDS OF PEOPLE AROUND THE WORLD MAKE OUR IMPACT POSSIBLE.

THANK YOU FOR CONSIDERING SUPPORTING OUR WORK TO PROVIDE ENCRYPTION FOR EVERYBODY.
