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
In good tradition, we're cooperating with the Cyber Security Coalition to host an experience sharing day. This separate event offers great insights into appsec in case you can't make it to SecAppDev. Registration and information available here: registration.invitedesk.com/p/en/xfdl86Er2… #appsec
Did you know that SecAppDev offers an unparalleled appsec experience? You will not find an AppSec course with such a great value for money. Don't believe us? Check out the program for 2025 and grab a seat! secappdev.org/2025/schedule/ #appsec #infosec
Our workshop program is complete and is looking amazing if you ask us. These hands-on workshops, taught by highly skilled security experts, are the perfect way to hone your security skills. EB discounts still available for one more week! secappdev.org/2025/workshops/ #appsec #infosec
The program for SecAppDev 2025 is 🔥🔥🔥 We have just dropped our first batch of lectures, so go check it out at secappdev.org/2025/lectures/ Remember, the early bird discount runs for 2 more weeks, so make sure to grab your seat! #appsec #infosec
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
Spot the difference! 👀 We goofed up and used the wrong speaker headshot in our last post. Our bad! The correct image is below—thanks for keeping us on our toes! #AttentionToDetail #Oops
We are so excited to announce the next batch of speakers for SecAppDev. This line-up is a great start to maybe our best program yet! Our early-bird discount runs until April 30th, and we also offer 50% discounts to SMEs. All info on secappdev.org #appsec #infosec
