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. Currently there’s just 1 sponsor blurb per issue.

Sounds Great, How Can I Make This Happen?

Fantastic, we look forward to working with you!

Reach out to newsletter AT tldrsec.com and we’ll work out the details 🎉

Sponsorship Details

Sponsoring the tl;dr sec newsletter entails a brief blurb (400-600 characters) about your product or an open job description that will be included in the tl;dr sec newsletter, blog, and social media posts + the call-to-action link.

Here are some illustrative templates.

Note: requirements and limitations for job and product ads may be changed at any time, but these changes will not be applied to already purchased sponsored issues except in very rare cases.

What Sort of Engagement Should I Expect?

Here are a few relevant metrics, please let me know if you there’s other info I can provide:


  • tl;dr sec currently has ~7,500 subscribers.
    • Given its current growth rate, I’d project 6K by March-ish 2021. I’m hoping for 10K by EOY, but we’ll see 🙂
  • tl;dr sec’s audience tends to be fairly technically minded, but ranges from ICs to Heads of AppSec/CloudSec/etc. all the way up to CISOs, VCs, and founders.
  • The companies represented are fairly diverse, from small start-ups to massive FAANG companies, from San Francisco Bay Area-based tech companies to healthcare, finance, and government.
  • Many readers are based out of the U.S., but there are readers all over the world.


  • Email open rates have consistently been ~40-50%.
  • The Twitter and LinkedIn posts announcing the issue typically receive 1K-5K and 1K-1.5K impressions, respectively.
  • Usually 11%-20% of readers click on at least one link in the email (~17% or so on average).
  • From email data alone (not including tldrsec.com or social media data), sponsor links typically range from ~10 - ~100 clicks.

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.

Terms and Conditions

From us:

  • tl;dr sec reserves the right to refuse sponsorship requests for any reason.
  • Sponsorship blurbs will be contained in a clearly demarcated section, and sponsoring an issue does not give any influence over the rest of the newsletter.
    • A competitor’s newly released tool, blog post, or talk may be referenced in the issue you sponsor.
    • Similarly, an article that negatively covers your company or product may be included in the issue you sponsor.
  • tl;dr sec will not officially endorse a company, product, or job description.
  • If you purchase a sponsorship of multiple issues at a time, you must use all of them within one year of purchase, else they are forfeited.

From you:

  • Your company placing an ad in tl;dr sec does not imply that your company endorses tl;dr sec or its views. It’s merely an ad placement.

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!
