🎓 Celebrating our newest Doctors!

As part of TalTech - Tallinna Tehnikaülikool's 108th anniversary celebrations on 17 September, 89 new doctors were promoted - including 16 researchers who defended their doctoral theses in the TalTech IT-teaduskond (School of IT).

Today, we want to give a special shoutout to three members of our cybersecurity research community:
🎓 Dr Marko Arik
🎓 Dr Rajesh Kalakoti
🎓 Dr Gabor Visky

A doctoral journey takes years of curiosity, persistence, hard work, countless questions, and probably more than just a few late nights. Seeing three of our own reach this milestone and stand up on that stage is something we are genuinely proud of ❤️

Their research contributes to the advancement of cybersecurity and information technology... but beyond the research and the titles, we are proud of the people and researchers they have become along the way.

And this achievement is never a solo effort. A big congratulations also goes to their supervisors, whose guidance, support and countless discussions helped make these journeys possible 👏

Marko, Rajesh and Gabor... congratulations, Doctors! We are incredibly proud of you and honoured to celebrate this remarkable achievement with you. Your dedication, curiosity and perseverance inspire us, and we look forward to seeing where your research journeys take you next.🖤

MENTE ET MANU. 🧠✋

🎉 Our Cybersecurity MSc Programme welcomes a record-breaking cohort of 63 new students!

We have a reason to celebrate! 🥳 This autumn, a record-breaking 63 new students will begin their studies in the Cybersecurity Master's programme at TalTech - Tallinna Tehnikaülikool - 39 from Estonia and 24 from abroad. 🌍

This is the largest intake we have had in a long time and the closest we have come to the enrolment limits set for our programme. We are especially happy to see such a strong international presence once again, with almost 40% of our new students coming from outside Estonia.

63 new students means 63 new stories, experiences and perspectives that will enrich our programme and student community. 💙 Having such an international cohort also creates a great opportunity to learn not only from our lecturers, but from each other by sharing experiences, knowledge and different perspectives on cybersecurity.

A big thank you to everyone who has contributed to making the programme attractive to students both in Estonia and internationally!

Congratulations to all of us, and a very warm welcome to our new IVCM students! 👋🎓

A new academic year, a new cohort and a record-breaking start... let’s make it a great one! 🚀

📚 Kooliaeg on jälle algamas? Mõtle enne, kui postitad.

Esimene koolipäev on tähtis sündmus iga noore elus. Uus koolikott, suured naeratused ja uhked vanemad - täiesti mõistetav, et tahaks seda rõõmu ka sotsiaalmeedias teistega jagada.

Enne kui vajutad nuppu „Postita“, mõtle korraks, kui palju infot sa tegelikult jagad...

Väldi postitustes järgmisi andmeid:

❌ Lapse täisnimi
❌ Kooli nimi või logo
❌ Klassijuhataja või õpetaja nimi
❌ Kodu aadress või muud asukohta tuvastavad detailid
❌ Sünnikuupäev või vanus
❌ Klass, tunniplaan või muu koolikorraldust puudutav info
❌ Fotod, millel on näha õpilaspilet, nimekaart või muu isiklik teave
❌ Koolivorm või riided, millel on selgelt nähtav kooli logo või mis on konkreetsele koolile iseloomulikud
❌ Huviringid, mida õpilane võib huviga oodata

✅ Hea nipp: Kui soovid teha traditsioonilise"esimese koolipäeva" foto, võta enne pildistamist koolivest või muu äratuntav koolivormi osa seljast ära. Tavaline särk või kampsun jätab mälestuse sama eriliseks, kuid ei reeda, millises koolis laps käib. Samuti oleks hea vältida pilte kooli ees või klassipingis kus on nähtavad ka teised õpilased.

Iga killuke isiklikku infot aitab võõrastel sinu lapse kohta tervikpilti kokku panna. Kurjategijad, petised ja veebikiskjad võivad näiliselt süütuid detaile kasutada usaldusväärse täiskasvanu kehastamiseks, turvaküsimustele vastuste äraarvamiseks või lapse usalduse võitmiseks.

🤍 Tähista olulist päeva, kuid kaitse oma lapse privaatsust 🤍

Turvaline kooliaasta algab mitte ainult kooliväravas, vaid ka internetis.

Jaga rõõmu, mitte isiklikke andmeid.

The Summer School Chronicles of USA and Moldova: Tallinn, Cybersecurity & Questionable Amounts of Fun ☀️🔐

This time around, we decided to do things differently. No weekly recaps. No "Week 1: We survived" followed by "Week 2: Somehow still alive." Instead, we're pulling the whole adventure together in one glorious summer-school-sized recap.

As always, we started with the basics: a tour of Tallinn and a tour of TalTech - Tallinna Tehnikaülikool. Because before we could unleash our students into the world of Estonian cybersecurity, they first needed to know where they were, where they were going, and, most importantly, where to find coffee and sustenance.

Then came the lectures. Lots and lots of lectures. Cybersecurity, technology, fascinating discussions and the occasional moment of "I'm sure this will make sense eventually." Spoiler: it usually did... we hope 🤞

But the classroom was only one part of the adventure.

We once again had the chance to visit some truly amazing places and meet some incredible people. A massive BIG UPS to NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE), CR14, TalTech Eesti Mereakadeemia (Maritime Academy), and e-Estonia for welcoming us and giving our students a peek behind the curtain of Estonia's cyber and technology ecosystem.

And then there were the secret visits 🤫.
We can't talk about those.
We can't tell you where we went.
We can't tell you what we saw.
We can only say...
They were EPIC.

Moving swiftly on. 👀

Our annual trip to Narva was next, where students got to experience a very different side of Estonia and see what life is like living right next door to our rather large neighbour. A city full of history, culture and a distinctly different atmosphere... and, naturally, plenty of opportunities to contemplate geopolitics while pretending you were only there for the sightseeing.

And then came the .

Because apparently we hadn't packed enough into the summer already.

Tallinn was in full football mode, with Freedom Square turning into the place to be for match nights. Students had the chance to watch the games together, cheer for their teams, and experience the age-old tradition of suddenly becoming a professional football analyst because you watched approximately 17 minutes of the match.

Argentina? Spain? Whoever you supported - for a little while, we were all united.

Well...

Until the referee made a questionable decision 👉 then all bets were off.

And so, somewhere between cybersecurity lectures, Tallinn adventures, secret missions, Narva trips and World Cup drama, the Summer School came to an end.

We arrived as students and organisers from different places.

We left with new friends, new knowledge, new memories - and possibly a few stories that will remain classified for the foreseeable future.

Until next summer. 🔐☀️⚽

Thank you to ESTDEV - Estonian Centre for International Development for helping finance our students from UTM - Universitatea Tehnica a Moldovei 💜

How we turned a national cybersecurity strategy workshop in Malta into a conversation about space. 🛰️🌍🔐

On 9 July, we joined Malta's vibrant cybersecurity community to discuss where the country's cybersecurity strategy has been, where it's going, and why the answer might occasionally involve looking up. 🚀

Stealing the spotlight was Johanna Kasenurm, Cybersecurity MSc student at TalTech IT-teaduskond, who took the audience on a journey from Earth to orbit and back again. She shared what we've been building at TalTech in the fields of space and space cybersecurity, why satellites need cyber protection too, and how securing something in space is a very different game from securing your average laptop or server.

Then came our favourite part: the room collectively discovering just how much of everyday life runs on things flying above our heads.

📡 Navigation? Satellites.

📡 Communications? Satellites.

📡 A surprising amount of modern life? Also satellites.

And once everyone realised this, the next question naturally followed:

"So… what happens if someone (cyber)attacks them?"

Exactly. 💡

The discussion quickly went from space is cool to space is critical infrastructure. We also explored how today's cybersecurity strategies fit with the space sector and why the next generation of strategies might need to reserve a seat at the table for orbit.

A huge thank you to the amazing Maltese cybersecurity community and National Cybersecurity Coordination Centre MT for the warm welcome, brilliant discussions, and curiosity. We left with new ideas, new connections, and the feeling that a few more people now look at the night sky and think:

"Hmm… we should probably secure that too." ✨🛰️

🌍🚁🛰️ Somewhere between land and space...

On June 19, our group took a short break from securing the digital world and exploring the space domain to spend a day in the sky at MTÜ Kuri Kotkas' drone flying training.

With beautiful weather overhead, our electronic eagles spread their wings as we learned the art of drone piloting - searching for objects in nature, delivering payloads to targets, and discovering that the airspace between Earth and orbit is a pretty fun place to be.

The day was filled with new skills, great company, and plenty of laughter. Most importantly, we strengthened our teamwork while adding another layer to our ever-growing toolbox.

After all, if your research spans from cyberspace to outer space, it only makes sense to make a stop in the sky every now and then. 😉🚁🛰️

Last week, Microsoft Teams couldn't tell us who was actually online.

This week, it won't matter.

As Mid-Summer approaches, security teams, IT admins, and office workers everywhere are preparing for the most effective digital detox of the year. Laptops will close. Notifications will be ignored. Teams statuses will finally start reflecting reality.

Unlike last week's outage, where online looked offline and offline looked online, the sea of grey dots you'll see over the next few days is likely to be completely accurate.

Across the country, people are disappearing into forests, summer cottages, saunas, and lakeside BBQs, leaving inboxes, chat channels, and security dashboards wondering where everybody went.

For a few glorious days, the biggest mystery won't be whether Teams is reporting someone's status correctly.

It'll be whether Mid-Summer can finally deliver a rain-free day.

Happy Mid-Summer to everyone enjoying the rarest cybersecurity control of all: an entire organization being genuinely offline. ☀️🔥🌿

𝐖𝐡𝐚𝐭 𝐢𝐟 𝐭𝐡𝐞 𝐛𝐢𝐠𝐠𝐞𝐬𝐭 𝐚𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞 𝐢𝐧 𝐜𝐲𝐛𝐞𝐫 𝐰𝐚𝐫𝐟𝐚𝐫𝐞 𝐢𝐬𝐧'𝐭 𝐛𝐞𝐭𝐭𝐞𝐫 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲... 𝐛𝐮𝐭 𝐚𝐜𝐜𝐞𝐩𝐭𝐢𝐧𝐠 𝐭𝐡𝐚𝐭 𝐲𝐨𝐮'𝐫𝐞 𝐭𝐡𝐞 𝐬𝐦𝐚𝐥𝐥𝐞𝐫 𝐚𝐧𝐝 𝐧𝐢𝐦𝐛𝐥𝐞𝐫 𝐟𝐨𝐫𝐜𝐞?

AI has flipped the script of cyber conflicts. Attacks are faster, cheaper, and increasingly automated. Defence can't rely on doing more of the same.

So what's the alternative?

Drawing on nearly two decades of Estonia's frontline cyber defence experience, our new , 𝐍𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐂𝐲𝐛𝐞𝐫 𝐑𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞 𝐢𝐧 𝐭𝐡𝐞 𝐀𝐠𝐞 𝐨𝐟 𝐀𝐈, lays out a doctrine for asymmetric cyber defence: how nations can make attacks less rewarding, defence more resilient, and crises less likely to happen.

Developed by experts from TalTech - Tallinna Tehnikaülikool, Nortal, Justiits- ja Digiministeerium / Ministry of Justice and Digital Affairs and Riigi Infosüsteemi Amet // Estonian Information System Authority (NCSC-EE) and other key players in Estonian private and public sector, the paper turns real-word experience into six practical policy moves for the already booming AI era.

If you're interested in cybersecurity, AI, national resilience or digital government - this is a conversation worth joining!

🚨🧠CYBER ALERT: THESIS DEFENCE SEASON HAS ENTERED THE CHAT🧠🚨

Somewhere inside TalTech IT-teaduskond, a very specific kind of chaos is about to begin:

📅 1–3 June
🎓 Master’s in Cybersecurity Thesis Defences
⚠️ Level: “systems are safe, but our nerves are not”

This is not just another academic milestone... this is the moment where two (or more) years of late nights all converge into a single point of truth:
✨the defence room✨

To every student stepping into that room:

You are not starting this journey here - you are finishing it at the point it has been building toward for two years. Every assignment, lab, and thesis iteration has been a build-up, even the frustrating ones that felt like detours at the time.

So, as you face the questions, the follow-ups, and the inevitable “can you clarify your methodology?”, remember: you already did the hardest part. You built something real, defended it against uncertainty, and made it through the process that got you here.

Good luck to everyone defending! May your arguments be clear, your systems stable, and your nerves only slightly unencrypted.

And most importantly: trust the work you’ve already done.
