Quantum computing has been surrounded by hype, uncertainty, and bold predictions. Some claim it will instantly break all encryption. Others dismiss it as a distant future concern.
In this NEVERHACK webinar, Louis Zezeran (Host, NEVERHACK Estonia) brings together three experts to provide clarity—cutting through the noise and focusing on what truly matters for organizations today.
Joining him are:
Together, they explore quantum computing from three critical angles: understanding the technology, assessing real-world risk, and building a practical roadmap for readiness.
The conversation begins with Guillaume Tassin, who provides a clear and accessible explanation of quantum computing.
Rather than positioning it as just a faster computer, Guillaume emphasizes that it is fundamentally different. While classical computers process information step by step, quantum computers can evaluate multiple possibilities simultaneously. This allows them to solve certain problems exponentially faster than today’s systems.
One of the most important implications of this capability is its impact on cryptography. Encryption methods that would take classical computers hundreds of years to break could, in theory, be solved in minutes with a sufficiently powerful quantum machine .
However, Guillaume also grounds the discussion in reality. Today’s quantum computers are:
They are not yet ready to disrupt global cybersecurity.
But that doesn’t mean organizations can ignore them.
Guillaume introduces the concept of “harvest now, decrypt later,” which becomes a central theme throughout the session.
The idea is simple:
This is particularly relevant for data that must remain secure over long periods—such as government communications, intellectual property, and personal data.
The risk is not immediate—but it is already in motion.
The discussion then shifts to Kalev Pihl, who brings decades of experience in digital identity and cryptographic systems.
Kalev provides a critical counterbalance to the hype, emphasizing that quantum risk is often overstated in popular discussions.
He explains that:
Kalev also highlights the complexity of real-world systems. For example, breaking a digital signature is not as simple as cracking a key—there are multiple layers of validation, including hashing, timestamping, and legal context.
One of his most valuable insights is that security is not purely technical—it is also societal.
Even if cryptographic systems are compromised:
This perspective reframes the discussion from pure technical risk to broader system resilience.
In the final segment, Marco Berardi focuses on what organizations should actually do.
His message is clear:
Post-quantum readiness is a process—not a product.
Marco outlines a structured three-phase approach:
Organizations must identify:
This includes evaluating:
This is often the most overlooked step.
Organizations need to map:
Without this visibility, migration cannot succeed.
This involves:
Marco emphasizes the importance of:
A key theme across the discussion is that the biggest challenge is not technology—it’s visibility and maturity.
Organizations that already have:
will be far better positioned to adapt.
Those without these foundations will face a much steeper challenge.
Kalev adds an important historical perspective: this is not the first time cryptography has evolved.
The industry has already gone through multiple transitions:
And while these transitions were not perfect, they were successful.
The same will happen with post-quantum cryptography.
A consistent message across all speakers is the importance of timing.
This is not an emergency—but it is not something to delay.
Regulatory guidance and industry expectations suggest:
Given the complexity of enterprise environments, this timeline is closer than it appears.

Iga kord, kui ettevõte kaotab kümneid või sadu tuhandeid eurosid petuarvete, võltsitud maksekorralduste või ärikirjapettuse tõttu, kasutatakse sama väljendit: “langeti küberrünnaku ohvriks.” Ehk oleks aeg rääkida ausalt: tegu ei olnud tehniliselt keeruka rünnakuga, vaid rünnak algas hästi üles ehitatud manipulatsiooniga, mille eesmärk oli panna inimene uskuma, et ta teeb argiseid ja hädavajalikke toiminguid.

Neverhacki ründava turbe juht Kaspar Jüristo pälvis Eesti esimesel riiklikul konkursil Digiauhinnad 2026 “Hea häkkeri” tunnustuse. Auhinna eesmärk on tunnustada nn valge kaabu eksperte, kelle töö aitab avastada kriitilisi turvanõrkusi enne, kui neid jõuavad ära kasutada kurjategijad. Kolmapäeval, 27. mail Telliskivi loomelinnakus toimunud pidulikul galal kuulutati välja Eesti esimese riikliku konkursi Digiauhinnad 2026 võitjad. Rambivalgusesse […]
Tehnoloogia areneb kiiremini, kui regulatsioonid ja inimeste teadmised järele jõuavad. Pettused muutuvad usutavamaks, tööriistad võimsamaks ja nende kasutamisega kaasnev mugavus kasvab samuti kiiresti, kirjutab Ronnie Jaanhold. Arst kuulab patsienti, keskendub ja küsib täpsustavaid küsimusi. Ta ei kirjuta midagi üles, sest vestlus salvestatakse ning tehisintellekt koostab sellest ise haigusloo. Arstil jääb nüüd rohkem aega patsiendi jaoks, […]
