It's this time of the year again ... kicking off the planning of SecAppDev 2026! While we work hard on an amazing program and immersive experience, you can already sign up for the 2026 edition using a blind bird discount. Hope to see you there! secappdev.org/ #appsec

Super excited to hear @evacide talk about Threat Modeling at @SecAppDev - such a fantastic speaker!

And it’s time to kick off @SecAppDev in Leuven, Belgium!

Speaking at #secappdev this week! secappdev.org/2025/speakers/…

SecAppDev is a full week software security course taught by a wide variety of educators from all over the world. I’m a huge fan of this course. I’m thrilled to be teaching there this year. It’s been over a decade since I joined SecAppDev’s staff. secappdev.org/2025/sessions/…

We've added a couple more speakers and a workshop to the line-up. The rest of the program is "under construction", and more details will appear online soon! Our early bird still runs till the end of the month. Hope to see you all at SecAppDev 2025! #appsec secappdev.org/

Bart Preneel will be giving a lecture at @SecAppDev this year, grab your seat now: secappdev.org/2025/speakers/…

Few people in cybersecurity have made as much real-world impact as Eva Galperin. Her work against stalkerware and surveillance tech has changed the game for online privacy. We are so excited to have her at SecAppDev 2025! More info and registration on secappdev.org

GO BELGIUM #SecAppDev

After 20 years in cybersecurity I never felt like I fit in. I’m not really a developer anymore and I was never a traditional security professional. My main expertise these days is PowerPoint, research and education. It’s been a joy carving my own path. It’s been incredibly fun. I feel like I cheated, bypassing most of the steps that many security professionals have had to pass through. Hard steps. While most spent years grinding as a pentester, developer or manager, I was making sure my PowerPoints looked pretty. As I sit here watching the keynote at #SecAppDev I realize just how fortunate I have been at @Manicode. Thank to you to everyone who has supported me over the past few decades. Friends, fellow professors, the OWASP community, and my amazing customers who have had faith in me and my business to work with their developer teams. This year was my biggest year at @Manicode. We keep growing slowly and continue to teach AppSec to developers one live class at a time and will continue to do so for many years to come. #greatful #gratitude #GratitudeDaily

Looking forward to speak at SecAppDev 2024 next week (twice!) Pick your poison: safe sandboxing of JavaScript code, or learning about the ins and outs of Ethereum and Solidity.

SecAppDev 2024 is only 2 weeks out, and the program is looking 🔥 We have two amazing keynotes lined up, along with 20 technical deep-dive sessions and 4 one-day hands-on workshops. We only have a handful of seats left, so don't hesitate too long! buff.ly/2JbEioy #appsec

Scaling software security is quite a challenge, and #OWASP #SAMM is a highly valuable project that can help you in this space. Learn all about it from Aram Hovsepyan at SecAppDev 2024. #appsec #infosec buff.ly/4a3Keek

None else than the ever-entertaining @manicode will talk about securing #React applications at SecAppDev 2024. Don't miss these valuable insights into React security. buff.ly/3ULbJVX #appsec #infosec

Learn how Google applies "Security Signals" to manage security at scale at SecAppDev 2024. Slawomir "Slawek" Goryczka will dive into the framework by using strict CSP as an example. More info available here: buff.ly/4bne26O #appsec #infosec

Agreed, it's really important and not really looked after. I gave a lecture at @SecAppDev and a speech at @ljcjug. Suprisingly, big conferences do not cater for this, but it's good that @Devoxx do! I shall submit next time :)

.@aghabagherloo wrote a blog post on the session "Security Engineering for Machine Learning" presented by Dr. Gary McGraw at #SecAppDev 2023. Check it out here: esat.kuleuven.be/cosic/blog/…

🚨 New video! 📽️ I use a #Rust app🦀 to explain how you can use Fetch Metadata to prevent cross-origin attacks like CSRF. I learned about this in a lecture by @we1x at #SecAppDev! youtu.be/vxz2eK9y0I4

SecAppDev 2023 was a blast with a week of enriching security insights! Slides are available on each of the lecture pages: buff.ly/45mSBRg Excited for next year's edition, which takes place in the week of June 3rd, 2024. Stay tuned! #SecAppDev2024
