This year’s Cybersecurity Summit 2025, held at Microsoft, was dominated by a single topic – phishing. Attacks that used to look amateurish have now turned into precise manipulation. Artificial intelligence, deepfakes and psychological tricks are making people the weakest link in even the best protected organisations.
The event was moderated by Ondřej Kubeček, Sales Director of System4U, and representatives of the company together with guests presented specific approaches to deal with this new reality.
Human.exe: attack without code
Jan Marek from Cyber Rangers took care of the opening, who in his lecture Human.exe showed how easy it is to “hack” a person.
“We can secure the technology. We can’t provide the people,” was heard in the hall.
He showed attacks where deepfakes, voice clones and personalised messages generated by artificial intelligence take the place of exploits.Phishing is no longer spam, but psychologically accurate manipulation.
Identity as a key
Roman Přikryl, teamleader of the System4U security and IAM team , followed up on the human factor.
He explained that user identity is the most valuable asset today – and its compromise is a frequent target of phishing.
Thanks to adaptive authentication, attacks can be detected before they cause damage:
“We track signals from logins – location, device, history. If something doesn’t match, access is blocked immediately,” said Přikryl.
A password is not enough. Neither does an MFA.
Ladislav Blažek, Technical Director of System4U, demonstrated a practical attack that can bypass multi-factor authentication.
He showed that the real defence is contextual security – combining identities, devices and network into one system, such as SecuRadar.
Network, device, human: the new security triangle
Daniel Vodrážka, infrastructure teamleader of System4U, closed the summit with a presentation on modern network security.
“The firewall is no longer enough. We need to understand the context – who is connecting, from where and why,” he summarised.
The new approaches can instantly isolate a device when a malicious link is clicked and prevent the attack from spreading further.
GoodAccess and new cooperation
Martin Čížek, Co-founder & CPO of GoodAccess, which is developing a European SASE/ZTNA platform available as a cloud service, was also part of the program.
GoodAccess focuses on simple and affordable remote connection security and identity-based access management.
The summit also announced the launch of a strategic collaboration between System4U and GoodAccess that will combine the benefits of SecuRadar and GoodAccess – i.e. surveillance, Zero Trust and secure access in one ecosystem.
The Cybersecurity Summit 2025 made it clear: Phishing is not just email. It’s psychology. And modern defence must combine technology, identity and human education.
