My betrayal list 👀💻☕️
→ “No budget for security this year - but we’re buying an AI platform.”
→ “This should only take a sprint”
→ “We’ll add auth later.”
→ Unpatched AI features quietly running in test environments.
→ “Can security approve this by EOD?”
→ That one ‘temporary’ AWS key from 2019 that’s now part of production folklore.
→ Vendors promising “end-to-end visibility.”
→ Compliance teams celebrating green checkmarks on broken controls.
→ Slack going down mid-incident.
What is on yours?? 👇🏾 (this is a safe zone 👀 😅 )

✨ Happy Onam to everyone celebrating!
🌍 “The thing I miss most about home isn’t the big festivals, it’s the little things only people from your town understand.” 👇🏾
Growing up, I never thought much about holidays.
I was the rebel kid, i would skip church events, resist family gatherings, and brush off festivals. To me, it all felt forced.
But now in my 30s, after years of being raised in India, Australia and now growing old in the U.K., my perspective has shifted.
I’ve come to see how much joy these celebrations bring not just my own, but also those of others. I grew up as a Christian surrounded by Hindus, Sikhs, Muslims, Jews, and so many others religions and cultures.
The beauty of the place was that
everyone had migrated from another town/country brought their own food, traditions, and ways of celebrating
and somehow, we all shared them.
Back then, I didn’t see the point.
Now, I feel grateful for those times and miss it on such days.
Because sometimes it’s not the big moments you long for...
but the tiny cultural details that remind you of where you came from.
And I’ve realized this isn’t just me.
Over the years,
I’ve met people from small towns in America, Ireland, the U.K., India, Australia and beyond.
Almost everyone who’s moved away for better opportunities or another reason shares a similar story:
➡️ There’s always a piece of your hometown you quietly miss.
Whether it’s a local festival.
A dish only your town makes a certain way.
Or even just a phrase that only makes sense back home.
Today, I find myself celebrating festivals like Onam - a 10-day harvest celebration from Kerala where families serve up to 35 dishes on a banana leaf.
As a child, I never valued it.
Today, as I pass food along the table to my loved ones, new friends and old,
it feels like a way to stay connected to my roots while
celebrating the diversity of others around me and
in some ways making this cool for other rebel kids who may not see it the same way today but 1 day will.
✨ Happy Onam to everyone celebrating!

ChatGPT-5 is dropping next month (Aug 2025),
almost 2 years after GPT-4 (Mar 2023).
But GPT-3.5 → GPT-4 took just 4 months 👀
🧠 How often should companies update their AI strategy?
The pace isn't linear, but the disruption is.
Can your AI strategy keeping up?

Learning about the Cloud Security & Cloud Pentesting space in UK & Europe from Nordic leaders and @nojonesuk 👇🏾
As part of the Nordic Security tour for @CloudSecurityPodcast , the last stop in the tour is Copenhagen and speaking to leaders in Pharma, Bank & more made me realise that in a lot of ways there is a gap in what cloud security should be vs what it is between the US, UK & Europe.
Some of the findings include
- CSPM or CNAPP is not always the answer e.g the CSPM alerts (if you use one of the mature ones like @paloaltonetworks , @wizsecurity , @Sentinelone-inc & others) are great start but there is a work required on top to know if the Risk value is actually accurate for the business
- Cloud Security D&R is a maturing space with Managed SOC fielding a lot of the Cloud detections and response.
- I also had a chance to talk to Nick Jones who i have known for a while through the Cloud Security community and we broke down what Cloud Pentesting looks like in the UK & Europe region and also where is a good place for people to start e.g it is easier to start with what you already know with cloud pentesting. If your pentesting scopes are usually based on crown jewels stick with that but include cloud too. More on this in an episode coming soon.
Curious if this is different to your experience in the Nordics across - Oslo, Stockholm, Helsinki? (comment below)
PS - That's the end of the Nordics tour too, thank you to everyone from our customer advisory and community who took the time to meet us and share their experience. Special shoutout to Marcus, Christian, Rami & others for the coffee chats & hugs too.
See you soon London - yes i missed you & i am bringing some codroid pants with me 😅 ❤️
