Hello and welcome to our coverage of InfoSecurity Europe 2025!

Held at London's Excel center, Infosec 2025 (as everyone actually calls it) is one of the biggest security-focused events on the calendar, packed with big names, informative talks, and news from the biggest firms around.

We're here in London and live on the ground for Infosec 2025 - here's what we've seen so far!

"Harvest now, decrypt later" is a huge talking point. The industries most at risk (unsurprisingly) are the 'critical national' warns Daniel Cuthbert - panel participant and cybersecurity expert. That means healthcare, finance, and telecoms could face serious difficulties in a PQC (post-quantum cryptography) world.

There's a myth, panel expert and Lastwall CEO Karl Holmqvist explains, that quantum computers can break any encryption. But really, at the moment, quantum computers can decrypt several commonly used encryptions - encryption will look different in the age of quantum, but it could still be effective. Cryptography will remain an important facet of cybersecurity for a long, long time - he argues.

Next, it's 'Quantum computing v Cybersecurity' - chaired by BBC News' Joe Tidy. Here, cybersecurity is described as an 'Arms Race' - although not everyone think that terminology is helpful!

Now, we're listening to Professor Brian Cox who's talking us through the link between cosmology and cybersecurity and computing. General relativity, the theory of space and time, and cosmology all link closely to quantum computing - with complex mathematics, data sets, and quantum mechanics.

There's a quick look back to how far cybersecurity has come in the last 30 years before Cluley explains that hackers aren't girlfriend-less men in garages anymore (his words!), but are serious, state sponsored actors - outlining an almost unrecognisable evolution in that InfoSec has helped to guide security experts through.

We're now seated for a super packed keynote, plenty of people are standing - so this is clearly a popular one! We're about to hear from Graham Cluley, host of the Smashing Security Podcast who'll introduce us all to Infosec's 30th year!

We're heading in to the show now!

As you can see from our pictures, the theme of Infosec 2025 is "Building a Safer Cyber World" - something you can bet we'll hear more about over the next few days.
