Who is the tl;dr sec community?

The tl;dr sec newsletter community is full of passionate security professionals who want to stay at the top of their game by keeping up with the latest security news, tools, resources, and current research at top security conferences.

Subscribers vary from hands-on security professionals working as application security engineers or SOC analysts, to security managers, to heads of application or product security, as well as CISOs, CSOs, security founders, and a VC or two.

What Does Sponsorship Look Like?

You can include a brief blurb about a job opening, your product, or your company that will be included in an issue of tl;dr sec.

This blurb will be included in:

The blurb will be placed right before the newsletter summary section block in the newsletter and blog post.

Note that the full text of the sponsor-provided blurb may not easily fit on social media platforms and may need to be condensed.

Your company, if desired, will be @Referenced on the relevant social media platform.

Clarifying What “Sponsorship” Means
Currently the unit of sponsorship is per tl;dr sec issue, as opposed to what conferences or some other media outlets do (e.g. having the homepage have a list of sponsors at the bottom that stays up for a few quarters / year, etc.) If you’re interested in a cross-issue, tl;dr sec-wide type sponsorship, reach out and we can discuss this further.

But as of today, what companies are doing is pre-purchasing a specific number of  “issues” up front and then selecting dates over one or more quarters to include ads in.

Sounds Great, How Can I Make This Happen?

Fantastic, we look forward to working with you!

Engagement Metrics: What I’ll Share

In order for you to better evaluate the ROI of your sponsorship, tl;dr sec will provide the following metrics for the issues you sponsor:

  • The number of unique users who opened the email
  • The number of unique users who clicked the sponsored link
  • The number of impressions and engagements on the associated tweet and LinkedIn Post

The privacy and trust of tl;dr sec subscribers is of paramount importance to us.

Thus, tl;dr sec will not provide:

  • The names, email addresses, or any other information about any tl;dr sec subscriber, including users who engaged with the newsletter sponsor link
  • Any information about users who engaged with the sponsored tweet thread or LinkedIn post

As there is a trailing window of when users open emails and see social media posts, tl;dr sec will provide these metrics approximately one week after the sponsored issue. Please let us know if there is a specific point in time that is most useful for you.

What Prior Sponsors are Saying

I’m not surprised tl;dr sec sells out far in advance - I was afraid that might be the case based on how well our own ads performed! :) We really did get quite a bit of attention from them, so congrats on the high quality readership!

tl;dr sec is one of our best performing venues. We’ll buy as many sponsored issues as you’ll sell us!
